Description

Technical Field

[0001] This utility model belongs to the field of automotive parts testing technology, specifically relating to an automotive air conditioning testing system that simulates a sandstorm environment. Background Technology

[0002] Automobiles are a common means of transportation in the current transportation field. Automobiles are mainly composed of multiple parts, including generators, chassis, braking systems and wheels. In order to ensure the comfort of driving, air conditioning is installed in the car to regulate the interior temperature. Before being installed in the car, the air conditioning system needs to undergo multiple testing procedures to calculate and test its operating life, operating efficiency, etc., including testing the air conditioning system under extreme weather conditions.

[0003] When air conditioners are tested in extreme weather, most tests focus on their operational stability in extremely cold or hot conditions. Current testing procedures do not include testing for air conditioners in dusty environments. In particular, with the deterioration of the environment, some cities experience dusty weather. Sand particles and other particulate matter in the dust can affect the air intake of the air conditioner. Existing air conditioner testing systems do not monitor this environment, which affects the overall performance of the car's air conditioner. Utility Model Content

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A car air conditioning testing system simulating a sandstorm environment includes a support base and a storage chamber. The storage chamber is installed on the support base and contains sand particles for subsequent testing. The main body of the car air conditioner is located on the side of the support base. The main body of the car air conditioner is an existing car air conditioner. A quantitative conveying component is installed below the storage chamber to quantitatively discharge the sand particles in the storage chamber. Below the quantitative conveying component is a sand delivery component that allows the sand particles to flow at a specific wind speed. The quantitative conveying component and the sand delivery component allow the sand particles to flow into the air intake port of the main body of the car air conditioner at a specific flow rate and a specific flow velocity.

[0007] As a preferred technical solution of this utility model, the quantitative conveying component includes an outer shell, a drive motor and a feeding auger. The outer shell is installed below the storage bin, and the feeding auger is rotatably installed inside the outer shell. The drive motor is installed at the end of the outer shell and is connected to the feeding auger. An inlet hole is provided at the connection between the outer shell and the storage bin, and a discharge hole is provided on one side of the outer wall of the outer shell. The discharge hole is located directly above the sand conveying component.

[0008] As a preferred technical solution of this utility model, the outer diameter of the feeding auger is fitted with the inner diameter of the outer shell, and the feeding auger will stably and quantitatively transport the sand particles entering from the inlet hole when it rotates.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0024] like Figure 1 and Figure 2 The diagram shows a schematic of the automotive air conditioning test system simulating a sandstorm environment in this embodiment. The test system installs the automotive air conditioner at a target location and, under specific wind conditions and sand volume, blows sand and other particulate matter into the air intake of the automotive air conditioner to test its stability under sandstorm conditions. The test system includes a support base 1, a storage chamber 2, and a quantitative conveying component 3. The storage chamber 2 is mounted on the support base 1 and contains sand particles required for subsequent testing. The quantitative conveying component 3 is installed at the bottom of the storage chamber 2, and it outputs a quantitative amount of sand particles from the storage chamber 2. A sand delivery component 4 is located below the quantitative conveying component 3, which blows the sand particles discharged from the quantitative conveying component 3, causing them to move along a specific path. The end of the sand delivery component 4 is equipped with the automotive air conditioner body 5, which inputs sand particles into the air intake of the automotive air conditioner body 5 to test its stability under specific wind conditions and sand volume.

[0025] In this embodiment, the storage chamber 2 mainly consists of a rectangular collection chamber and a conical discharge chamber. The rectangular collection chamber is installed on the support base 1. The rectangular collection chamber is a cylindrical structure with openings at the top and bottom. A conical discharge chamber is installed at the bottom opening of the rectangular collection chamber. The conical discharge chamber can guide the sand particles to be discharged in a concentrated manner at the top of the conical discharge chamber, which facilitates the subsequent quantitative conveying component 3 to receive and convey the sand particles.

[0026] As attached Figure 3 and Figure 4As shown, this is a schematic diagram of the quantitative conveying component 3 in this embodiment. The quantitative conveying component 3 includes an outer shell 31, a drive motor 32, and a feeding auger 33. The outer shell 31 is installed below the storage bin 2. The outer shell 31 is a hollow, closed cylindrical structure. An inlet hole is provided at the connection between the outer shell 31 and the storage bin 2. Sand particles are input into the outer shell 31 through the inlet hole. The drive motor 32 is installed at the end of the outer shell 31. The feeding auger 33 is installed at the output end of the drive motor 32. The feeding auger 33 rotates inside the outer shell 31. When sand particles enter the outer shell 31, the drive motor 32 drives the feeding auger 33 to rotate. Under the rotation of the feeding auger 33, the sand particles inside the outer shell 31 are quantitatively and stably conveyed. A discharge hole is provided on the side wall of the outer shell 31. The discharge hole is located directly above the sand conveying component 4. The sand particles conveyed inside the outer shell 31 are discharged through the discharge hole and enter the sand conveying component 4.

[0027] In this embodiment, the rotation speed of the feeding auger 33 is linked to the sand conveying flow rate. By controlling the rotation speed of the feeding auger 33, the purpose of quantitatively outputting sand can be achieved.

[0028] As attached Figure 5 and Figure 6 As shown, this is a structural schematic diagram of the sand feeding assembly 4 in this embodiment. The sand feeding assembly 4 includes a mounting base 41, a blower body 42, a sand inlet pipe 43, and an air outlet pipe 44. The mounting base 41 is provided on the side of the support base 1, and the blower body 42 is mounted on the mounting base 41. The sand inlet pipe 43 is installed at the air inlet end of the blower body 42. The opening at the end of the sand inlet pipe 43 is located directly below the discharge hole. Sand particles discharged from the discharge hole fall directly into the sand inlet pipe 43. The air outlet end of the blower body 42 is installed with an air outlet pipe 44. Sand particles are output through the air outlet pipe 44, and a conveying pipe 45 is installed at the end of the air outlet pipe 44. The air intake hood 46 is fitted onto the end of the car air conditioning unit 5. Sand particles transported by the exhaust pipe 44 enter the car air conditioning unit 5 under the guidance of the transport pipe 45 and the air intake hood 46. When the blower body 42 is running, the flow rate of the sand particles is controlled by the operating power of the blower body 42 itself, which simulates the situation of sand particles flying in the environment. A support frame 47 is set below the car air conditioning unit 5. The support frame 47 supports and installs the end of the car air conditioning unit 5, so that the car air conditioning unit 5 is stably attached to the end of the air intake hood 46, and assists the car air conditioning unit 5 in receiving sand particles.

[0029] In this embodiment, the air outlet pipe 44, the conveying pipe 45, and the air inlet hood 46 constitute a conveying assembly. The conveying assembly is used to assist sand particles in entering the air inlet of the car air conditioning unit 5 stably, so as to facilitate subsequent testing of the operating effect of the car air conditioning unit 5 in a sandstorm environment.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
