Description

Technical Field

[0001] This utility model relates to automotive parts testing equipment, and more particularly to an automotive parts vibration testing device with a dust circulation structure. Background Technology

[0002] When a car travels in a dusty environment, dust can easily enter the vibrating components, causing malfunctions or jamming noises, necessitating testing with a testing device. Patent document CN115265977A discloses a vibration testing device, comprising a vibration table body, a transmission assembly, and a drive assembly. Springs are embedded near the corners of the upper part of the vibration table body, and a rectangular carrier plate is embedded at the upper end of each spring. The transmission assembly is connected to the lower end of the carrier plate near its four corners, and its vertical movement drives the carrier plate to vibrate. The drive assembly is installed inside the vibration table body and connected to the transmission assembly, driving the transmission assembly to move vertically. The connection position between the transmission assembly and the carrier plate corresponds to the position of the springs, thus better counteracting the reaction force generated by the springs and increasing the area covered by the force, enhancing stability. However, this testing device can only perform vibration testing independently of dustproof testing and cannot simulate the actual driving conditions of a car. Therefore, it is necessary to optimize the structure of this testing device to overcome the aforementioned shortcomings. Utility Model Content

[0006] A support assembly assembly is mounted in the frame via connectors and has an internal assembly space.

[0007] A shielding and protective assembly is installed in a support assembly and has an internal receiving space;

[0008] A vibration receiving assembly is located between the support assembly assembly and the shielding protection assembly, and cooperates with a drive mechanism, which drives the vibration receiving assembly to vibrate between the support assembly assembly and the support assembly assembly.

[0009] The dust-carrying and dust-collecting assembly is located in the shielding and protective assembly and is connected to the vibration receiving assembly. It has a dust-raising space and a dust-returning space inside. The automotive parts can be placed in the dust-raising space. The vibration receiving assembly drives the dust-carrying and dust-collecting assembly and the automotive parts it carries to vibrate.

The transition partition component divides the containment space inside the shielding and protection component, so that it is connected to the dust-generating space and the dust-returning space respectively.

[0011] The dust circulation component has a dust inlet connected to the dust return space of the dust storage component and a dust outlet connected to the dust emission space of the dust storage component. The dust circulation component transports the dust in the dust storage component to the dust emission space, so that the dust comes into contact with the automotive parts.

[0012] Specifically, the supporting assembly components include:

[0013] A support base plate is arranged laterally and installed in the frame via a connector, with a clearance opening in its middle.

[0014] The shielding and protection components include:

[0017] Vibration receiving components include:

[0018] A vibration stage is located in an obstruction opening and cooperates with a drive mechanism. Its top protrudes from above the support base plate, and the drive mechanism drives the vibration stage to vibrate.

[0019] The dust collection assembly includes:

[0020] The carrier has a dust storage chamber inside, which forms a dust return space. Its top has a support platform for placing automotive parts, which forms a dust emission space. The support platform has through holes, and the dust emission space is connected to the dust return space through the through holes, so that the dust remaining after contact with the automotive parts enters the dust storage chamber through the through holes.

[0021] The transition separation component includes:

[0022] A separating membrane is located above the carrier base. Its outer edge is joined to the inner wall of the shield side panel, and its inner edge is joined to the outer wall of the carrier base. The separating membrane separates the containment space formed by the shield side panel and the protective top panel, allowing it to communicate with the dust-generating space and the dust-returning space respectively.

[0023] The dust recycling components include:

[0024] A circulating fan is located on the outside of the shield side panel;

[0025] The dust inlet pipe passes through the side panel of the cover and extends into the dust storage chamber inside the carrier body, and is connected to the air inlet of the circulating fan.

[0026] The dust outlet pipe passes through the side panel of the cover and points to the top of the carrier body. It is connected to the air outlet of the circulating fan. The circulating fan draws the dust in the dust storage chamber out from the dust inlet pipe and transports it from the dust outlet pipe to the carrier body and the car parts it carries.

[0027] The advantages of this utility model are:

[0028] This testing device, through the cooperation of a vibration receiving component and a dust-collecting component, can simulate the vibration and dust environment that automotive parts may encounter during driving. This helps to evaluate the durability and reliability of parts under actual use conditions. The dust circulation component allows dust to circulate between the dust-generating space and the dust-returning space, which not only reduces dust waste but also ensures continuous contact between dust and automotive parts, thus providing a more comprehensive test of the dustproof performance of the parts. Since dust circulation and vibration testing are performed simultaneously, testing efficiency can be greatly improved. By adjusting parameters such as vibration frequency and dust concentration, testing conditions can be precisely controlled to meet the testing needs of different parts. Attached Figure Description
