The application provides a test system, which comprises a test platform 30 and an article 100 to be tested, wherein the test platform 30 is used for performing waterproof test on the article 100 to be tested.

The test platform 30 may be classified into a plurality of waterproof test classes such as IPX1 to IPX9 according to the waterproof test classes, and the waterproof test requirements of each waterproof test class are different. Illustratively, using a waterproof test grade of IPX9K as an example, the liquid sprayed by the test platform 30 may be a pressurized heated liquid. In some alternative embodiments, the test platform 30 with a waterproof test rating of IPX9K may meet the following test criteria:

standard one: the water flow rate may be between 14L/min and 16L/min, the water pressure may be between 8000kPa and 10000kPa, the water temperature may be between 75 ℃ and 85 ℃, the rotational speed of the component for carrying the object 100 to be tested may be between 6r/min and 7r/min, the injection time at each position may be 30s at 0 °, 30 °, 60 °, 90 °, 100 ° -150 °.

And (2) a second standard: for small test articles 100 having a maximum dimension of no more than 250mm, the water temperature may be between 75 ℃ and 85 ℃, and the rotational speed of the components for carrying the test article 100 may be between 6r/min and 7r/min, with spraying at 0 °, 30 °, 60 °, 90 °, 100 ° -150 °. For a large-sized article 100 to be measured with a maximum size of 250mm or more, in the case of meeting the standards of a small-sized article 100 to be measured, it is also necessary to spray from all directions to cover the entire surface of the article 100 to be measured, and the spray angle should be as perpendicular to the spray surface as possible, and the distance between the liquid outlet 321 and the article 100 to be measured is between 150mm and 200 mm. The area calculation can be calculated according to the object to be measured 100, the duration of each square meter test is 1min, and the object to be measured 100 is sprayed for a minimum of 3min.

The article to be tested 100 may include, but is not limited to, the battery 1, the battery cell 10, other electrical products requiring corresponding waterproof performance, etc., and the following embodiments mainly describe the article to be tested 100 as the battery 1.

The battery 1 mentioned in the art can be classified into a disposable battery and a rechargeable battery according to whether it is rechargeable or not. Disposable batteries (Primary batteries) are also known as "disposable" batteries and galvanic cells, because they cannot be recharged for use after their charge has been exhausted and can only be discarded. Rechargeable batteries are also known as secondary (Secondary Battery) or secondary, accumulator batteries. The rechargeable battery is made of different materials and process from the primary battery, and has the advantages of being capable of being recycled for multiple times after being charged, and the output current load force of the rechargeable battery is higher than that of most of the primary batteries. The types of rechargeable batteries that are currently common are: lead acid batteries, nickel hydrogen batteries, and lithium ion batteries. The lithium ion battery has the advantages of light weight, large capacity (the capacity is 1.5-2 times of that of the nickel-hydrogen battery with the same weight), no memory effect and the like, and has very low self-discharge rate, so that the lithium ion battery is widely applied even though the price is relatively high. Lithium ion batteries are also widely used in pure electric vehicles and hybrid vehicles at present, and the capacity of the lithium ion batteries used for the purposes is relatively slightly low, but the lithium ion batteries have larger output and charging currents, longer service lives and higher cost.

In the embodiments of the present application, the battery 1 described refers to a rechargeable battery or a disposable battery. Hereinafter, embodiments of the present disclosure will be described mainly by taking a lithium ion battery as an example. It should be appreciated that the disclosed embodiments are applicable to any other suitable type of rechargeable battery. The battery 1 according to the embodiments disclosed in the present application may be directly or indirectly applied to a suitable device to supply power to the device.

In the embodiment of the application, the battery 1 can be used as an operating power supply of a vehicle, and can also be used as a driving power supply of the vehicle to supply driving power for the vehicle instead of or in part of fuel oil or natural gas.

In some embodiments, the shape of the battery 1 may include, but is not limited to, square, cylindrical, or any other shape. The battery 1 may include a housing 20 and a battery cell 10, the battery cell 10 being accommodated within the housing 20. The case 20 serves to provide a receiving space for the battery cell 10, and the case 20 may take various structures. In some embodiments, the housing 20 may include a first portion 21 and a second portion 22, the first portion 21 and the second portion 22 overlapping each other, the first portion 21 and the second portion 22 together defining an accommodating space for accommodating the battery cell 10. The second portion 22 may be a hollow structure with one end opened, the first portion 21 may be a plate-shaped structure, and the first portion 21 covers the opening side of the second portion 22, so that the first portion 21 and the second portion 22 together define an accommodating space; the first portion 21 and the second portion 22 may be hollow structures each having an opening at one side, and the opening side of the first portion 21 is engaged with the opening side of the second portion 22.

The casing 20 may be made of a material having a certain hardness and strength, so that the casing 20 is not easy to deform when being extruded and collided, and the safety performance of the battery cell 10 is improved, for example, the material of the casing 20 may include, but is not limited to, a steel casing, an aluminum casing, a plastic casing (such as polypropylene), a composite metal casing (such as a copper-aluminum composite casing), or an aluminum-plastic film. The housing 20 may take any shape, for example, the shape of the housing 20 includes, but is not limited to, square, cylindrical, prismatic, etc. The housing 20 may be an internally hollow structure, and the interior of the housing 20 may be used to house electrodes, electrolytes, and sensor assemblies, among other things.

Among them, the waterproof test of the battery 1 is understood to be the waterproof test of the case 20 of the battery 1. When the test platform 30 is used to perform the waterproof test on the article 100 to be tested, water needs to be sprayed to the article 100 to be tested from various angles of the article 100 to be tested, and how to perform the omnibearing and effective water spraying test on the article 100 to be tested through a simple structure is a problem to be solved.

Based on the above technical basis, the present application provides a test platform 30, where the test platform 30 includes a turntable 200, the turntable 200 has a first rotation axis 210, and the turntable 200 is used for driving the to-be-tested object 100 placed on the turntable 200 to rotate around the first rotation axis 210. The turntable 200 has a rotation function, and the turntable 200 may be rotated by a driving device such as a motor, etc., and illustratively, the entire turntable 200 may be rotated about the first rotation axis 210, or only a part of the turntable 200 for placing the object 100 to be measured may be rotated about the first rotation axis 210. The first rotation axis 210 may be a center line of the turntable 200, or any line parallel to and not coincident with the center line of the turntable 200, when the article 100 to be measured is placed on the turntable 200, the center line of the article 100 to be measured may be coincident with the first rotation axis 210, so as to reduce the risk that the article 100 to be measured is separated from the turntable 200 during the rotation process.

The test platform 30 further comprises a liquid outlet device 300, the liquid outlet device 300 comprising a nozzle holder 310 and a nozzle assembly 320, the nozzle holder 310 being connected to the nozzle assembly 320, a liquid outlet 321 of the nozzle assembly 320 being directed towards the object to be tested 100, the nozzle holder 310 defining a movement path 311, the nozzle assembly 320 being movable along the movement path 311 relative to the nozzle holder 310 for rotating the nozzle assembly 320 about a second axis of rotation 330 perpendicular to the first axis of rotation 210.

The nozzle assembly 320 can be used to spray liquid from the liquid outlet 321 to the object 100 to be tested, so as to perform a waterproof test on the object 100 to be tested. When the article 100 to be measured is placed on the turntable 200, the liquid outlet 321 of the nozzle assembly 320 faces the article 100 to be measured, and when the article 100 to be measured rotates around the first rotation axis 210, if the number of the nozzle assemblies 320 is one, the nozzle assemblies 320 can be sprayed on the peripheral surface of the article 100 to be measured even if the angle of the nozzle assemblies 320 is not changed.

The nozzle support 310 defines a movement path 311, and the nozzle assembly 320 can move along the movement path 311 relative to the nozzle support 310, so that the relative position between the nozzle assembly 320 and the article 100 to be measured can be adjusted only by moving the nozzle assembly 320, which can improve the convenience of moving the nozzle assembly 320 compared with moving the nozzle assembly 320 by moving the nozzle support 310, so as to adjust the relative position between the nozzle assembly 320 and the article 100 to be measured by a simpler structure. The movement path 311 may be a straight path, a curved path, or a movement path 311 formed by a straight plus curved line, so long as the nozzle assembly 320 can be rotated about the second rotation axis 330. The motion path 311 may be a complete circumferential path or a non-complete circumferential path, and illustratively, taking the motion path 311 as a circular arc path, the motion path 311 may include, but is not limited to, 1/4 circular motion, 1/2 circular motion, or the entire circular motion, with 1/4 circular motion enabling a smaller structure of the nozzle holder 310 and 1/2 circular motion enabling a larger coverage area of the nozzle holder 310.

Through the above embodiment, the liquid outlet 321 of the nozzle assembly 320 faces the article 100 to be tested, the turntable 200 drives the article 100 to be tested to rotate around the first rotation axis 210, and the nozzle assembly 320 and the nozzle support 310 can move relatively, so that the nozzle assembly 320 can rotate around the second rotation axis 330 perpendicular to the first rotation axis 210, and the relative position between the liquid outlet 321 of the nozzle assembly 320 and the article 100 to be tested can be adjusted in the three-dimensional space, so that the waterproof test can be performed on the article 100 to be tested through a simpler structure, the complexity of the test platform 30 is reduced, and the effectiveness of the waterproof test on the article 100 to be tested is improved.

Referring to fig. 3, fig. 3 is a schematic illustration of an assembly of nozzle holder 310 and nozzle assembly 320 according to one or more embodiments.

The nozzle holder 310 includes a first clamp plate 312 and a second clamp plate 313 disposed at a distance, the first clamp plate 312 and the second clamp plate 313 cooperate to form a movement path 311, the nozzle assembly 320 includes a nozzle 322 and a slider 324 coupled to the nozzle 322, the nozzle 322 being partially disposed between the first clamp plate 312 and the second clamp plate 313, the slider 324 moving on the movement path 311 to move the nozzle 322 on the movement path 311.

The first and second clamping plates 312 and 313 may be of the same structure at least at the portion where the movement path 311 is formed, so that the movement path 311 is formed by the cooperation of the first and second clamping plates 312 and 313, for example, when the movement path 311 is a circular arc and the movement path 311 is formed by the side edges of the first and second clamping plates 312 and 313, the radius of curvature of the side edges of the first and second clamping plates 312 and 313 for forming the movement path 311 may be the same to cooperatively form the movement path 311. The movement path 311 may be formed by the side edges of the first clamping plate 312 and the second clamping plate 313 facing away from the turntable 200, or the movement path 311 may be formed by the side edges of the first clamping plate 312 and the second clamping plate 313 facing the turntable 200.

The nozzle 322 is partially located between the first clamp plate 312 and the second clamp plate 313, for example, the nozzle 322 may be spaced apart from the first clamp plate 312 and the second clamp plate 313, or the nozzle 322 may be in contact with at least one of the first clamp plate 312 and the second clamp plate 313. In other embodiments, nozzle holder 310 may include only one clamp plate, with nozzle 322 on one side of the clamp plate, and the cooperation of first clamp plate 312 and second clamp plate 313 may provide better stability for sliding member 324 moving along motion path 311, while providing a clamp plate may provide a more compact overall structure. Therefore, the nozzle 322 is partially disposed between the first clamping plate 312 and the second clamping plate 313, so that the nozzle 322 can be limited by the first clamping plate 312 and the second clamping plate 313, and when the slider 324 drives the nozzle 322 to move on the movement path 311, the slider 324 can conveniently move relative to the nozzle bracket 310 along the sliding path, and the stability of the slider 324 is further increased.
