Description

Technical Field

[0001] This utility model relates to the field of testing technology for new energy battery equipment, and in particular to an airtightness testing device for a housing. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Battery pack thermal management for new energy vehicles can be mainly divided into four categories: natural cooling, air cooling, liquid cooling, and direct cooling. Liquid cooling and air cooling both require circulation within the battery pack to dissipate heat, thus necessitating a sealed, dustproof, and waterproof battery pack. However, the airtightness testing of battery packs mostly relies on instruments to determine whether the pack is sealed. Existing airtightness testing equipment is inconvenient in terms of material loading and unloading during testing, severely impacting its usability. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0026] First, using sections 1-3, the overall structure of this airtightness testing device for a housing will be described. Figure 1 This is a three-dimensional structural diagram of the present invention. Figure 2 This is a three-dimensional schematic diagram of the feeding fixture 3 in this utility model. Figure 3 This is a three-dimensional schematic diagram of the top pressing mechanism 4 in this utility model.

[0027] The airtightness testing equipment for the enclosure includes a support platform 1, an airtightness testing chamber 2, a feeding fixture 3, a top clamping mechanism 4, and a PLC control system, wherein:

[0028] The PLC control system is electrically connected to the electrical components inside the equipment to coordinate and control the operation of the equipment, so as to realize the automatic detection of the airtightness of the enclosure.

[0029] The support platform 1 is rectangular in shape and is used to install the airtightness test chamber 2;

[0030] The airtightness test chamber 2 is a box with an internal space. The airtightness test chamber 2 is located on the top surface of the support platform 1. The airtightness test chamber 2 is equipped with airtightness testing instruments and components. When the box 100 is transported into the airtightness test chamber 2, the airtightness test chamber 2 can test the airtightness of the box 100.

[0031] The loading fixture 3 is movably mounted on the support platform 1. The airtightness test chamber 2 has an opening for the loading fixture 3 to move into the interior of the airtightness test chamber 2.

[0032] The loading fixture 3 includes a support base 301, a first side clamping mechanism, and a second side clamping mechanism. The bottom of the support base 301 is movably mounted on the support platform 1. The first side clamping mechanism is installed on the first side of the support base 301 to clamp the first side, and the second side clamping mechanism is installed on the second side of the support base 301. When it is necessary to test the airtightness of the housing 100, the housing 100 can be mounted on the support base 301, and the first and second side clamping mechanisms can clamp the housing 100. Then, the support base 301 moves the housing 100 together into the airtightness test chamber 2 for airtightness testing.

[0033] The top pressing mechanism 4 is located inside the support platform 1 and is used to press the top of the box 100. Through the cooperation of the top pressing mechanism 4, the first side pressing mechanism and the second side pressing mechanism, the box 100 can be pressed onto the support base 301. After the air tightness testing instrument inside the air tightness testing chamber 2 completes the air tightness test of the box 100, the top pressing mechanism 4 rises and the support base 301 drives the box 100 to move out of the air tightness testing chamber 2. The loading and unloading of the box 100 is convenient and facilitates the air tightness test of the box 100.

[0034] In some embodiments, such as Figure 2-3 As shown, two slide rails 5 are installed on the support platform 1, spaced apart. A slider 6, adapted to the slide rails 5, is installed at the bottom of the support base 301. The number and position of the sliders 6 are matched with the slide rails 5, and the sliders 6 are slidably mounted on the slide rails 5. In this embodiment, through the cooperation of the slide rails 5 and the sliders 6, the support platform 1 can reciprocate on the support platform 1.

[0035] In some embodiments, such as Figure 3 As shown, a drive mechanism is installed on the support platform 1 and at the bottom of the support base 301. The drive mechanism can drive the support base 301 to reciprocate along the slide rail 5. The drive mechanism is a drive cylinder 17, which can be a multi-cylinder assembly. The output end of the drive cylinder 17 is fixedly connected to one side of the support base 301.

[0036] In this embodiment, the support platform 1 is provided with a mounting slot for installing the drive cylinder 17. The drive cylinder 17 is installed in the mounting slot and is electrically connected to the PLC control system. When the housing 100 on the support platform 1 needs to be tested for air tightness, the PLC control system controls the drive cylinder 17 to start. The drive cylinder 17 can move the support platform 1 and the housing 100 on the support platform 1 into the air tightness test chamber 2. Then, the air tightness test instrument in the air tightness test chamber 2 is used to test the air tightness of the housing 100. After the air tightness test is completed, the drive cylinder 17 can move the support platform 1 and the housing 100 on the support platform 1 to the outside of the air tightness test chamber 2, thereby realizing automatic feeding and automatic unloading, improving convenience and ease of use.

[0037] In some embodiments, such as Figure 2 As shown, the first side clamping mechanism includes a first cylinder 7 and a first pressure plate 8. The first cylinder 7 is installed on the first side of the support base 301, and the first pressure plate 8 is installed on the output end of the first cylinder 7. The second side clamping mechanism includes a second cylinder 9 and a second pressure plate 10. The second cylinder 9 is installed on the second side of the support base 301, and the first side and the second side are arranged adjacent to each other.

[0038] In this embodiment, both the first cylinder 7 and the second cylinder 9 are electrically connected to the PLC control system. When performing an airtightness test, the PLC control system controls the first cylinder 7 and the second cylinder 9 to start. The first cylinder 7 drives the first pressure plate 8 to press the first side of the housing 100 tightly. The second cylinder 9 drives the second pressure plate 10 to press the second side of the housing 100 tightly, thereby firmly pressing the housing 100 onto the support platform 1.

[0039] In some embodiments, such as Figure 3 As shown, the top pressing mechanism 4 includes a lifting cylinder 111, a lower pressing platform 11, and several elastic pressing heads 12. The lifting cylinder 111 is installed on the top surface of the airtightness test chamber 2, the lower pressing platform 11 is located inside the airtightness test chamber 2, the output end of the lifting cylinder 111 is installed on the top surface of the lower pressing platform 11, and the several elastic pressing heads 12 are arranged at intervals on the bottom surface of the lower pressing platform 11. In this embodiment, the PLC control system is electrically connected to the lifting cylinder 111. Under the control of the PLC control system, the lifting cylinder 111 can drive the lower pressing platform 11 and the several elastic pressing heads 12 on the lower pressing platform 11 to press the top of the chamber 100.

[0040] In some embodiments, such as Figure 3As shown, the lower pressure platform 11 is equipped with a guiding mechanism, which includes guide rails 13 and sliding sleeves 14. There are four guide rails 13, with their upper and lower ends installed around the perimeter of the airtightness testing chamber 2. The guide rails 13 are mounted on the support platform 1, and the sliding sleeves 14 are fixedly connected to the lower pressure platform 11. The sliding sleeves 14 can be sleeved onto the guide rails 13, allowing the lower pressure platform 11 to reciprocate up and down along the length of the guide rails 13. In this embodiment, the cooperation between the guide rails 13 and the sliding sleeves 14 guides the lower pressure platform 11, ensuring the accuracy of the pressure position of the lower pressure platform 11 on the chamber 100.

[0041] In some embodiments, such as Figure 3 As shown, four limiting posts 15 are installed at the bottom of the pressing platform 11. The top ends of the four limiting posts 15 are fixedly installed to the bottom of the pressing platform 11. A connector 16 adapted to the limiting posts 15 is installed on the top surface of the support base 301. When the pressing platform 11 is pressed down, the bottom ends of the limiting posts 15 are inserted into the top opening of the connector 16. In this embodiment, through the cooperation of the limiting posts 15 and the connector 16, the pressing platform 11 can be pressed down more precisely onto the support base 301.
