Description

Technical Field

[0001] This invention relates to the field of high and low temperature testing equipment, and more specifically, to a high-load explosion-proof integrated environmentally friendly high and low temperature testing equipment. Background Technology

[0002] The core of high and low temperature shock and damp heat cycling tests is to "simulate real environmental stress, accurately control test parameters, and verify performance and safety in all dimensions." Differentiated test designs are made for the product characteristics of batteries and electronic appliances (such as SOC control and explosion protection for batteries, and power-on load and sealing tests for electronic appliances). The entire process follows national / industry standards. At the same time, through failure analysis after testing, product design improvements are deduced, ultimately improving the environmental reliability of products.

[0003] Existing high and low temperature testing devices are mostly standardized, single-category adaptable designs, primarily developed around the testing needs of conventional electronic appliances or single-specification batteries. When faced with complex scenarios such as testing multiple types of samples in the same chamber, cross-testing of multiple national / industry standards, coupled testing under extreme conditions, and continuous testing of high-risk samples, technical shortcomings emerge in core dimensions such as temperature field control, safety protection, interface linkage, structural adaptation, and program compatibility. They cannot meet the stringent testing requirements of different national / industry standards, nor can they adapt to the special safety requirements of multiple types of samples, such as explosion-proof and short-circuit protection. Ultimately, this leads to distorted test data and potential safety hazards in the testing process. Summary of the Invention

[0030] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Refer to the instruction manual appendix Figures 1 to 3 A high-load explosion-proof integrated environmentally friendly high and low temperature test device includes an explosion-proof enclosure. The main enclosure consists of a main enclosure 1 and a secondary enclosure 2. Both sides of the main enclosure 1 are connected to door panels 13 via hinges. An electrical protection system is installed on the door panels 13, including cable brackets 14. An external interface 15 is provided on the door panels 13. A lock 16 connects the door panels 13 and the main enclosure 1. A ventilation port 17 is provided on the top of the main enclosure 1. A safety explosion-proof system is installed on the top of the main enclosure 1. The explosion system includes a pressure relief port 18, which is located on one side of the ventilation port 17. Explosion-proof chains 19 are installed on both the main housing 1 and the door panel 13. A temperature field regulation system is installed on the auxiliary housing 2, which includes a windproof water pump 21. Water inlet and outlet pipes 22 are provided on one side of the windproof water pump 21. An air storage tank 25 is installed inside the auxiliary housing 2. A refrigeration temperature control system is installed at the bottom of the auxiliary housing 2, which includes a condenser 26. A CO2 compressor 27 is provided on one side of the condenser 26.

[0032] It should be noted that the main housing 1 has a test chamber inside. The main housing 1 and the auxiliary housing 2 are made of explosion-proof stainless steel and lined with ceramic fiber insulation layer, which can withstand high temperature of up to 1500℃. The door panel 13 is located in the middle of the main housing 1. The cable bracket 14 is located on one side of the external interface 15, and multiple sets of cable brackets 14 are arranged vertically. The lock 16 includes an electromagnetic bolt lock and a safety lock, which are used to lock the main housing 1 and the door panel 13. The gas tank 25, the condenser 26 and the CO2 compressor 27 are all connected to the test chamber of the main housing 1.

[0033] A control panel 11 is installed at one end of the main housing 1, and an observation window 12 is embedded in the control panel 11.

[0034] It should be noted that the control panel 11 is equipped with a touch screen, supports programmed temperature curves, data recording and remote communication, which facilitates automated management, and the observation window 12 is embedded with a transparent plate.

[0035] The electrical protection system includes a communication board 23, which is installed at one end of the sub-box 2. A leakage current switch 24 is installed on one side of the sub-box 2.

[0036] It should be noted that the communication board 23 uses existing remote communication technology, and the leakage current switch 24 connects the power supply line and internal electrical components.

[0037] The main housing 1 is equipped with a three-color light, and both the main housing 1 and the auxiliary housing 2 are equipped with casters at the bottom.

[0038] It should be noted that the three-color lights are used to provide light signals, and the casters facilitate the movement of the main housing 1 and the auxiliary housing 2.

[0039] In this embodiment, the specific implementation scenario is as follows: A refrigeration temperature control system composed of a condenser 26 and a CO2 compressor 27 provides a basis for precise high and low temperature control and rapid temperature change. Using CO2 refrigeration reduces energy consumption by 30%. A temperature field regulation system composed of an air exchange port 17, a windproof water pump 21, and inlet and outlet water pipes 22 ensures uniform temperature and humidity and condensation control. Using a PID algorithm, the temperature resolution reaches 0.01℃, and the uniformity is ≤2℃. It can achieve precise control of ±0.5℃ within a temperature range of -70℃ to +150℃, with a heating and cooling rate of 1-10℃ / min. A safety explosion-proof system composed of a pressure relief port 18, an explosion-proof chain 19, and a gas storage tank 25 provides multiple protections against thermal runaway of the test sample. It can instantly relieve pressure in the event of a sample explosion to prevent shock wave leakage. An electrical protection system composed of a cable bracket 14, an external interface 15, a communication board 23, and a leakage current switch 24 provides additional protection. The explosion-proof enclosure ensures electrical safety, multi-device linkage, and reliable data transmission. In the military and aerospace industries, it can be used for extreme environmental reliability testing of special materials, ammunition, and electronic components, simulating harsh conditions such as high and low temperatures and vacuum. In the petrochemical industry, it can be used to evaluate the thermal stability and explosion-proof performance of chemical materials, valves, and electronic components in flammable and explosive gas environments. In the automotive and electronics industries, it can be used to test batteries and electronic appliances under high and low temperature shock and damp heat cycling to verify their performance and safety. In the food and biopharmaceutical industries, it can precisely control temperature in drug synthesis and food processing to ensure component stability and prevent microbial growth. Through the coordinated work of various systems, the explosion-proof enclosure can meet the testing requirements of various types of samples according to national / industry standards, and can also adapt to the special safety requirements of various types of sample testing, such as explosion-proof and short-circuit protection, ensuring the accuracy of test data and the safety of the testing process.

[0040] In existing technologies for high-temperature shock testing of battery cells, the cells must be placed inside a transport basket and cannot directly contact the inner chamber of the test chamber. The specific steps are as follows: First, the battery cell sample is pre-treated by fully insulating the tabs and cleaning the outer shell. Then, the transport basket is pre-positioned by placing a customized insulated transport basket on the test bench, leveling the basket, and confirming that the positioning holes are not blocked / deformed and that there are no metal debris inside the basket. Next, the sensor is attached by attaching a high-temperature resistant probe to the middle section of the battery cell shell and fixing it with high-temperature insulating adhesive. The probe does not cover the positioning hole, and only one probe is attached to each battery cell. Then, the battery cell with the probe attached is vertically placed into the positioning hole, ensuring that there is no hard compression between the bottom of the battery cell and the bottom of the positioning hole, no contact between the shell and the hole wall, and that the tabs are all facing upwards. Finally, the spacing of the positioning hole array is controlled to be ≥3cm. The top of the battery cell should be at least 5cm from the top edge of the transfer basket, and the battery cell should be at least 2cm from the inner wall of the basket, with no contact whatsoever. This ensures that the high-temperature air duct penetrates the battery cell completely. Next, the wiring is arranged so that the temperature monitoring wire is led out along the cutout of the transfer basket. The wiring should not entangle the battery cell or block the positioning holes. The wiring is fixed on the outside of the basket, with a wire length extension allowance of at least 10cm. Finally, the transfer basket is placed into the test area / transfer track of the impact test chamber, ensuring that the basket and track are not loose or stuck. The transfer basket is placed in the center of the chamber, at least 5cm from the inner wall / high-temperature air vent, without blocking the air duct and pressure relief port. When placing the battery cell in the transfer basket, it is required to be placed upright to prevent rolling, with each cell independently positioned, without loosening during transfer, without obstruction of the temperature, and with the tabs fully insulated.

[0041] Some drone battery compartments have streamlined, irregularly shaped structures adapted to the fuselage. Their power battery modules require the use of rectangular cells of different lengths and widths, as well as cylindrical cells of different diameters. However, the positioning hole diameter of the universal transfer basket in the existing technology is fixed, which can only load cells with the same value for testing. Therefore, multiple sets of transfer baskets need to be customized according to the cells with the same value in the power battery module, which not only affects the accuracy of the test results, but also increases the test cost.

[0042] Refer to the instruction manual appendix Figures 3 to 11 The main housing 1 has a mobile cart 3 installed inside, and a transfer basket 4 is slidably mounted on the mobile cart 3. A carrier plate assembly 7 is installed at the bottom of the transfer basket 4. The transfer basket 4 is used to place the battery cells 5.

[0043] It should be noted that the mobile vehicle 3 moves the transfer basket 4 within the test chamber of the main housing 1, and battery cells 5 of different diameters and lengths can be placed on the transfer basket 4.

[0044] The mobile vehicle 3 includes a main seat 31, a guide rail 32 is mounted on the main seat 31, a guide rail 33 is mounted on the output end of the guide rail 32, a transfer basket 4 is mounted on the output end of the guide rail 33, and a drive seat 34 is mounted on the bottom of the main seat 31.

[0045] It should be noted that the transfer basket 4 can move along the X-axis and Z-axis on the main seat 31 via guide rail 1 32 and guide rail 2 33, and the bottom of the main seat 31 is equipped with casters.

[0046] The top of the transfer basket 4 is detachably installed with a top plate 41, and a ventilated plate 42 is provided on the top plate 41. Ventilated plates 42 are also embedded around the transfer basket 4.

[0047] It should be noted that the top plate 41 has several sets of ventilated plates 42, and the ventilated plates 42 are mesh plate components.

[0048] The top plate 41 is fixedly provided with a guide block 43, and at least two sets of guide blocks 43 are provided on both sides of the bottom of the vent plate 42. A movable block 44 is slidably provided on the guide block 43, and the movable block 44 is located on the outside of the battery cell 5.

[0049] It should be noted that the side of the guide block 43 corresponding to the movable block 44 is a slope, the side of the movable block 44 corresponding to the guide block 43 is a slope, and the side of the movable block 44 away from the guide block 43 is a vertical surface.

[0050] A pull rod assembly 6 is threaded onto the top plate 41. The bottom end of the pull rod assembly 6 is rotatably connected to the slider 61. The guide block 43 and the movable block 44 both have an installation port 45 inside. The top end of the movable block 44 has a groove 46. The slider 61 slides laterally along the inside of the groove 46.

[0051] It should be noted that the pull rod assembly 6 and the slider 61 are rotatably connected by a T-shaped cross section. Rotating the pull rod assembly 6 can push the movable block 44 to slide obliquely downward along the inclined surface of the guide block 43, so that the two sets of movable blocks 44 are brought closer to each other. The mounting port 45 is used to install the sensor, and the wiring is arranged through the mounting port 45 of the guide block 43.

[0052] The carrier plate assembly 7 includes a long carrier plate 71, one end of which is fixedly connected to a short carrier plate 72. Both the long carrier plate 71 and the short carrier plate 72 are provided with positioning holes 73, and a pad 74 is fitted onto the positioning holes 73.

[0053] It should be noted that the shape of the positioning hole 73 is set to a circle, rectangle or other shape according to the shape of the battery cell, and the height of the multiple sets of pads 74 is different.

[0054] In this embodiment, the specific implementation scenario is as follows: Open the door panel 13, pull the main seat 31 outward from the test chamber of the main housing 1, insert the battery cell 5 into the vent plate 42, insert the bottom of the longer battery cell 5 into the positioning hole 73, and prop up the shorter battery cell 5 with the pad 74 to ensure that the tops of all battery cells 5 are aligned and at least one-third of the top is exposed outside the top plate 41, so as to position and prevent tipping through the top plate 41. Twist the pull rod assembly 6, and slide the slider 61 laterally along the inside of the slide groove 46 to push the movable block 44 equipped with the sensor diagonally downward until the vertical surface of the movable block 44 contacts the battery. The sensor at the mounting port 45 is brought into contact with the surface of the cell 5 to position the cell 5. Then, the main seat 31 is placed back into the test chamber of the main housing 1. The X-axis and Z-axis positions of the transfer basket 4 are adjusted by the guide rail 1 32 and guide rail 2 33 to move it to the test point. The transfer basket 4 can accommodate rectangular cells of different lengths and widths, as well as cylindrical cells of different diameters. The actual cell arrangement of the battery module can be reproduced through the carrier plate assembly 7, which can better reproduce the actual arrangement of cells with different values ​​in the battery module for testing. This not only provides accurate test results but also saves testing costs.

[0055] Working principle: First, open the door panel 13 and pull the main seat 31 out of the test chamber of the main body 1.

[0056] Second, insert the battery cell 5 into the vent plate 42. Insert the bottom of the long battery cell 5 into the positioning hole 73, and prop up the short battery cell 5 with the pad 74 to ensure that the tops of all the battery cells 5 are aligned and that at least one-third of the top is exposed outside the top plate 41.

[0057] Third, turn the pull rod assembly 6 to slide the slider 61 laterally along the inside of the slide groove 46, and push the movable block 44 with the sensor on it diagonally downward until the vertical surface of the movable block 44 contacts the surface of the battery cell 5, so that the sensor at the mounting port 45 abuts against the surface of the battery cell 5 and positions the battery cell 5.

[0058] Fourth, the main seat 31 is then placed back into the test chamber of the main housing 1, and the X-axis and Z-axis positions of the transfer basket 4 are adjusted by guide rail 1 32 and guide rail 2 33 to move it to the test point.

[0059] V. Finally, start the corresponding systems of the main chamber 1 and the auxiliary chamber 2 to conduct high and low temperature impact tests.

[0060] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
