Description

Technical Field

[0001] This utility model relates to the technical field of automotive component testing equipment, specifically to an ice water impact testing device. Background Technology

[0002] During winter vehicle operation, cold ground water can splash onto hot automotive system components. Rapid temperature changes can cause materials with different coefficients of thermal expansion to crack or seals to fail, leading to vehicle performance and safety issues. Therefore, in the production and research of automotive products, ice water impact tests are conducted to test the durability of automotive products in environments with extreme temperature changes.

[0003] Common ice-water impact tests include two methods: spraying and immersion. To increase the practicality of ice-water impact test chambers, common ice-water impact test chambers not only include a low-temperature impact chamber, but also a high-temperature chamber that can subject the specimen to high-temperature impact. First, the specimen is placed in the high-temperature chamber and heated to the required test temperature. Then, the specimen is removed from the high-temperature chamber and placed in the low-temperature chamber for ice-water impact testing. After the test time is up, the specimen is removed for testing.

[0004] The transfer of the specimen from the high-temperature chamber to the low-temperature chamber relies on manual operation, which not only reduces the convenience of the ice-water impact test, but also reduces the accuracy of the test results due to the specimen coming into contact with the external environment during the transfer, thus reducing the test efficiency of the ice-water impact test.

[0005] To address the aforementioned technical problems, existing technology, known as a "chill-water impact test chamber," provides a chill-water testing device. This device includes a chamber with a partition plate dividing it into an upper high-temperature chamber and a lower low-temperature chamber. A heating element is located within the high-temperature chamber, and a chilled water tank is located within the low-temperature chamber. A vertically adjustable basket is installed within the chamber. A connecting opening for the basket is provided on the partition plate, and a control mechanism at the opening controls its opening and closing. Initially, the basket is located in the high-temperature chamber. The specimen is placed inside the basket. Once the specimen reaches a specified temperature, the moving end of the linear drive extends, increasing the chain length between the basket and the sprocket. Simultaneously, the basket moves downwards under its own weight, causing the chain to move downwards, which in turn rotates the sprocket until the basket is inside the chilled water tank, completing the impact test.

[0006] This device eliminates the need to remove the specimen from the high-temperature chamber and place it in the low-temperature chamber, improving the convenience of the ice-water impact test. Furthermore, the specimen remains within the chamber throughout the transfer process, unaffected by the external environment, thus enhancing the accuracy and efficiency of the test results. However, this device also presents some challenges. The basket containing the components enters the low-temperature chamber from top to bottom. While this works well for individual components, it is less effective for electrically powered products. The test requires the application of both high-voltage and low-voltage DC power. During the lifting and lowering process, the high- and low-voltage wiring harnesses of electrically powered products are susceptible to water ingress and electrical leakage due to external forces, posing a risk to equipment and personnel. Utility Model Content

[0007] The purpose of this application is to address the shortcomings of the aforementioned background technology and provide an ice-water impact testing device.

[0008] The technical solution of this application is: a water-ice impact testing device, comprising,

[0011] According to the ice-water impact testing device provided in this application, the driving structure includes a top plate and a bottom plate fixed to the bottom of the cooling water tank; a scissor brace for driving the top plate to rise and fall is provided between the top plate and the bottom plate.

[0012] According to the ice-water impact testing device provided in this application, the bottom of the high-temperature chamber is provided with a through hole for the cooling water tank to pass through; the through hole is provided with an isolation structure to isolate the cooling water tank and the high-temperature chamber when the cooling water tank does not enter the high-temperature chamber.

[0013] According to the ice-water impact testing device provided in this application, the isolation structure includes a flap; one end of the flap is rotatably hinged to the side wall of the through hole, and the other end seals and isolates the high-temperature chamber and the cooling water tank when flipped to a horizontal state.

[0014] According to the ice-water impact testing device provided in this application, two sets of oppositely arranged flaps are provided at the through hole, and the ends of the two sets of flaps abut together to seal the through hole when flipped to a horizontal state.

[0017] The advantages of this application are: 1. The ice water impact test device of this application is designed with a movable cooling water tank, which can raise the cooling water tank when ice water impact test is required so that the product to be tested is immersed in the cooling water tank.

This application provides a through hole at the bottom of the high-temperature chamber and an isolation structure at the through hole location, which can effectively block heat transfer between the cooling water tank and the high-temperature chamber. The high-temperature ambient temperature and the low-temperature chilled water temperature do not affect each other, which not only makes the temperature uniformity of the high-temperature chamber and the cooling water tank better, but also saves energy; it avoids the cooling water tank and the high-temperature chamber being connected, which would cause the temperature to affect each other, resulting in large differences in temperature uniformity and more energy consumption.

[0020] 4. The isolation structure of this application is extremely simple. The through hole can be well sealed by the partition. When flipped to the horizontal state, it can effectively block the heat transfer between the cooling water tank and the high temperature chamber.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] This application relates to an ice-water impact testing device. The testing device of this application is used to conduct ice-water impact tests on products. The testing device of this application can complete the ice-water impact test of the product while keeping the product under test stationary. The energized product and high and low voltage wiring harnesses remain in the same position during the immersion ice-water impact test, which reduces the possibility of water entering the waterproof plugs and sealing rings on the product and wiring harness due to external forces, and improves the safety of equipment and personnel.

[0033] Specifically, such as Figures 1-2 As shown, the ice-water impact testing apparatus of this application includes a high-temperature chamber 1 and a cooling water tank 2. The high-temperature chamber 1 is a hollow chamber structure that creates a high-temperature environment inside. A shelf 3 is provided inside the high-temperature chamber 1 for placing the test parts. The test parts are placed inside the shelf 3 and are exposed to the high-temperature environment inside the high-temperature chamber 1. The cooling water tank 2 is a hollow chamber located below the high-temperature chamber 1, creating a low-temperature environment for the internal components. The cooling water tank 2 has an opening at the top and a drive structure at the bottom for vertically moving the cooling water tank 2 into the high-temperature chamber 1, thus allowing the shelf 3 to enter the cooling water tank 2. The cooling water tank 2 is a movable structure, capable of entering the high-temperature chamber 1 to conduct ice-water impact tests on the parts inside the shelf 3 when necessary.

[0034] In the actual test, the parts to be tested are placed in the shelf 3, the wiring harnesses and other connecting structures on the parts are connected, and the wiring harnesses are connected to the external power supply of the high temperature chamber 1. The high temperature chamber 1 constructs a high temperature environment. After the high temperature environment constructed by the high temperature chamber 1 and the cooling water temperature in the cooling water tank 2 reach the set requirements, it is maintained for 1 hour. Then, within 20 seconds, the cooling water tank 2 is driven vertically upward into the high temperature chamber 1 through the drive structure, so that the parts in the shelf 3 are completely immersed in the ice water in the cooling water tank 2. This is maintained for 5 minutes to complete the ice water impact test.

[0035] In some embodiments of this application, the above-described driving structure has been optimized, such as... Figures 1-2 As shown, the driving structure of this embodiment includes a top plate 4 and a bottom plate 5 fixed to the bottom of the cooling water tank 2. A scissor brace 6 for driving the top plate 4 to rise and fall is provided between the top plate 4 and the bottom plate 5. The top plate 4 and the bottom plate 5 are provided with a sliding groove structure. The upper and lower ends of the scissor brace 6 are slidably connected in the sliding groove. When it is necessary to adjust the vertical height of the top plate 4, the included angle of the scissor brace 6 can be changed to make the upper and lower ends of the scissor brace 6 slide in the corresponding sliding groove, thereby adjusting the vertical height between the top plate 4 and the bottom plate 5.

[0036] In practical applications, this driving structure is not the only one that can be used. Other lifting driving structures can also be used, as long as they can meet the requirement of adjusting the vertical movement of the cooling water tank 2.

[0037] In other embodiments of this application, the structure of the high-temperature chamber 1 described above has been optimized, specifically, as follows: Figures 1-2 As shown, in order to facilitate the entry and exit of the cooling water tank 2 into the high-temperature chamber 1, a through hole is provided at the bottom of the high-temperature chamber 1 for the cooling water tank 2 to pass through. An isolation structure is provided at the through hole to isolate the cooling water tank 2 from the high-temperature chamber 1 when the cooling water tank 2 does not enter the high-temperature chamber 1.

[0038] like Figures 1-2 As shown, the isolation structure includes a flap 7, one end of which is rotatably hinged to the side wall of the through hole, and the other end of which seals the through hole to isolate the high-temperature chamber 1 and the cooling water tank 2 when flipped to a horizontal state. In addition, in this embodiment, two sets of flaps 7 are provided at the through hole, which are arranged opposite to each other. When the two sets of flaps 7 are flipped to a horizontal state, their ends abut together to seal the through hole.

[0039] The flap 7 is connected to the through hole through a hinged structure. When the cooling water tank 2 needs to enter the high temperature chamber 1, the cooling water tank 2 passes through the through hole vertically. The upper end of the cooling water tank 2 pushes the flap 7 upward and passes through the through hole into the high temperature chamber 2. The flap 7 is placed on both sides of the cooling water tank 2. When the ice water impact test is completed, the cooling water tank 2 moves vertically downward under the drive of the drive structure. The cooling water tank 2 moves out of the high temperature chamber 1 through the through hole. The flap 7 closes onto the through hole under the action of gravity, completing the closure of the through hole and blocking the cooling water tank 2 and the high temperature chamber 1.

[0040] The high-temperature chamber 1 and the cooling water tank 2 are isolated from each other by a flap 7, so that the high-temperature ambient temperature and the low-temperature ice water temperature do not affect each other. This not only makes the temperature uniformity of the high-temperature chamber 1 and the cooling water tank 2 better, but also saves energy. It avoids the high-temperature chamber 1 and the cooling water tank 2 being connected, which would cause the temperature to affect each other, resulting in large differences in temperature uniformity and more energy consumption.

[0041] In a preferred embodiment of this application, the internal structure of the high-temperature chamber 1 described above has been further optimized, such as... Figure 1 As shown, the shelf 3 in this embodiment is a hollow frame structure with an open top. It is essentially a square frame structure formed by connecting multiple rod-like structures. The open top facilitates the placement of components. This embodiment is not limited to this type of square frame structure composed of rod-like structures; other hollow forms are also possible, such as a square frame structure made of flat plates with multiple small holes. The key is to ensure that after the shelf is immersed in the ice water in the cooling water tank 2, the ice water can quickly enter the shelf 3.

[0042] Two sets of support rods 8 are arranged horizontally inside the high-temperature chamber 1. The two sets of support rods 8 are placed on both sides of the upper end of the shelf 3 and fixedly connected to the upper end of the shelf 3. The two sets of support rods 8 suspend the shelf 3 inside the high-temperature chamber 1, placing the shelf 3 in the exact center of the high-temperature chamber 1. The support rods 8 also serve as a limiting structure for the rise of the cooling water tank 2. That is, after the cooling water tank 2 passes through the through hole into the high-temperature chamber 1, and rises to its upper end and contacts the support rod 8, it can be considered that the cooling water tank 2 has risen to its correct position.

[0043] When the ice-water impact testing device of this application is actually tested, the component to be tested is placed in the shelf 3, the wiring harness and other connection structures on the component are connected, and the wiring harness is connected to the external power supply of the high temperature chamber 1. The high temperature chamber 1 constructs a high temperature environment. After the high temperature environment constructed by the high temperature chamber 1 and the cooling water temperature in the cooling water tank 2 reach the set requirements, it is maintained for 1 hour. Then, within 20 seconds, the top plate 4 is pushed vertically upward by the drive scissor brace 6. The upper end of the cooling water tank 2 passes through the through hole and pushes the top plate 7 upward and flips it upward. The cooling water tank 2 passes through the through hole and completely enters the high temperature chamber 1 until the cooling water tank 2 moves up to the shelf 3 and completely falls into the cooling water tank 2. The shelf 3 is completely immersed in the ice water in the cooling water tank 2. The ice water permeates the shelf 3 and soaks the component in the shelf 3. It is maintained for 5 minutes to complete the ice-water impact test of the component.

[0044] The top plate 4 is driven to move downward by the scissor brace 6. The top plate 4 and the cooling water tank 2 move downward until the cooling water tank 2 completely passes through the through hole and moves out of the high temperature chamber 1. The flip plate 7 automatically flips to a horizontal state under the action of gravity and covers the through hole, thus sealing the high temperature chamber 1.
