Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, specifically a battery temperature resistance testing device. Background Technology

[0002] New energy batteries refer to devices that utilize renewable energy (such as solar and wind power) or low-carbon energy (such as lithium-ion and sodium-ion) to store and release energy. It is a technology capable of converting and storing energy, providing crucial support for the large-scale application of renewable energy. During the manufacturing process, temperature resistance testing devices are used to test the limits of the new energy batteries' cold and heat resistance.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a battery temperature resistance testing device, including a housing 1, a movable door 2, a cooler 3, a heater 4, a shelf 5, an adsorber 6, and a sealing plug 7.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the housing 1 is hollow, with an opening on one side. A movable door 2 is rotatably connected to the opening side of the housing 1. A cylinder 21 is fixed to the bottom of the movable door 2 near the housing 1. A pressing rubber plate 22 is fixed to the output end of the cylinder 21. The cylinder 21 drives the pressing rubber plate 22 to move back and forth inside the housing 1, so that the pressing rubber plate 22 can press the new energy battery and limit its movement. A refrigerator 3 and a heater 4 are fixed on the adjacent sides of the opening side of the housing 1, respectively. A cold air vent 11 is opened on the side wall of the housing 1 where it connects to the refrigerator 3, and a hot air vent (not shown) is opened on the side wall of the housing 1 where it connects to the heater 4. A first air inlet 31 is opened on the refrigerator 3, and a second air inlet 4 is opened on the heater 4. 0. The cooler 3 cools the air through the first air inlet 31 and then introduces it into the housing 1 through the cold air outlet 11 to conduct cold resistance tests on the new energy battery. The heater 4 heats the air through the second air inlet 40 and then introduces it into the housing 1 through the hot air outlet to conduct heat resistance tests on the new energy battery. Both the cooler 3 and the heater 4 are existing technologies. The middle of the outer wall of the heater 4 is fixed with a first button 41, a second button 42, and a third button 43 along the Z-axis. Display screens 44 are fixed on both sides of the outer wall of the heater 4. The first button 41 can control the switch of the heater 4, the second button 42 can control the switch of the cooler 3, and the third button 43 can control the switch of the cylinder 21. The relevant controls are completed by the cooperation of the control mechanism. The control program is existing technology.

[0029] like Figure 2 As shown, the bottom of the box 1 is provided with multiple sliding grooves 12 along the X-axis. The sliding grooves 12 are slidably connected to the shelf 5 by the moving strip 13. The shelf 5 is provided with a handle 51 on the outside of the shelf 5, which makes it easy to pull out the shelf 5 and convenient to place new energy batteries.

[0030] like Figure 1 , Figure 4As shown, a vent 14 is provided through the top wall of the housing 1. An adsorber 6 is fixed inside the vent 14. A sealing plug 7 is detachably connected to the top of the adsorber 6. The adsorber 6 includes a treatment box 61, snap-fit ​​strips 62, and adsorption strips 63. The treatment box 61 is fixed inside the vent 14. The treatment box 61 is hollow from top to bottom. Multiple snap-fit ​​strips 62 are fixed at stepped intervals on the top of the treatment box 61. Adsorption strips 63 are fixed at the bottom of each snap-fit ​​strip 62. The adsorption strips 63 can adsorb most of the odor in the gas, thereby reducing the emission of odor. At the same time, the adsorption strips 63 are not arranged on the same horizontal line, which can leave a lot of gaps in the vent 14 to facilitate exhaust.

[0031] like Figure 1 As shown, a thermosensitive color-changing material strip 15 is fixed on the top of the heating unit 4 on the box 1. When the inside of the box 1 is in a high-temperature state, the thermosensitive color-changing material strip 15 can change color to warn the staff; the thermosensitive color-changing material strip 15 is rectangular.

[0032] In use, open the movable door 2, pull out the shelf 5, place the new energy battery on the shelf 5, and then push it into the box 1. Close the movable door 2 and use the third button 43 to activate the cylinder 21, causing the cylinder 21 to move back and forth inside the box 1. This allows the pressure rubber plate 22 at the end of the cylinder 21 to push the rear side of the new energy battery against the inner rear wall of the box 1, thus limiting the position of the new energy battery. Then, activate the cooler 3 using the second button 42, allowing outside air to enter the cooler 3 through the first air inlet 31. The generated cold air enters the box 1 through the cold air outlet 11. The accumulation of a large amount of cold air lowers the temperature inside the box 1, thus conducting a cold resistance test on the new energy battery. When a heat resistance test is required, use the heater 4 to heat the air. The accumulation of a large amount of hot air increases the temperature inside the box 1, thus conducting a heat resistance test on the new energy battery. The thermochromic material strip 15 changes color according to the temperature of the chamber 1, allowing staff to more intuitively understand the internal temperature of the chamber 1. The thermochromic material strip 15 is relatively inexpensive (compared to a temperature sensor) and is directly attached to the chamber 1. The color change can alert staff to temperature changes, without requiring precise temperature readings, thus serving as a warning to prevent staff from approaching the chamber 1. After work is completed, the sealing plug 7 is opened, and the gas inside the chamber 1 is discharged through the vent 14. At the same time, the treatment box 61 at the upper end of the vent 14 is equipped with an adsorption strip 63, which can adsorb most of the odor in the gas, thereby reducing odor emissions. Prioritized exhaust can prevent hot or cold air from rushing towards staff when the movable door 2 is opened, effectively preventing harm to staff. The vent 14 has a relatively large diameter, which can quickly discharge the hot and cold air inside the chamber 1.
