Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a fixture for testing seat massage airbags. Background Technology

[0002] In the production and R&D of automotive seats, conducting airtightness and burst pressure tests on the built-in massage airbags is a crucial step in ensuring product quality and safety. According to relevant testing standards, airtightness tests often require simulating the actual working state of the airbag within the seat, applying a certain load and limiting its expansion height; while burst tests require the airbag to be securely fixed in a rigid structure to test the maximum pressure it can withstand.

[0003] Currently, most existing testing fixtures are specialized clamps designed for specific types of airbags, resulting in poor versatility. When testing airbags of different sizes or models is required, the fixtures need to be replaced or remanufactured, leading to high testing costs and low efficiency. More importantly, many existing fixtures cannot simultaneously meet the following three core requirements: 1. The distance between the upper and lower plates can be easily adjusted and locked to accommodate airbags of different thicknesses or expansion heights; 2. The standard required counterweight load can be easily applied to the upper plate during airtightness testing; 3. Sufficiently rigid locking can be provided during burst testing to prevent fixture failure when the airbag bursts.

[0004] Therefore, there is an urgent need to develop a universal fixing clamp that can take into account height adjustment, load application, and secure locking. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a simple, easy-to-operate, versatile, and durable fixing clamp for testing seat massage airbags.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixture for testing a seat massage airbag includes a base plate with a vertically positioned positioning post on the base plate. A slider with a locking function is slidably mounted on the positioning post. An upper plate is connected to the slider and is arranged parallel to and opposite to the base plate. The slider includes a locking bearing sleeved on the positioning post, a collar connected to the locking bearing, a locking bolt for positioning on the collar, and a handle connected to the locking bolt.

[0008] As a preferred embodiment of this invention, the number of positioning posts is four, which are located at the four corners of the base plate.

[0009] As a preferred embodiment of this invention, the locking bearing is provided with multiple sets of ball bearings inside.

[0010] As a preferred embodiment of this invention, when the locking bolt is tightened, the end of the locking bolt presses against the surface of the positioning post, thereby locking the slider in its current position.

[0011] As a preferred embodiment of this invention, the surface area of ​​the upper plate is larger than the horizontal projected area of ​​the massage airbag of the seat to be tested.

[0012] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are:

[0013] 1. This utility model provides a fixture for testing massage airbags in a chair. The fixture is height-adjustable and highly versatile. By loosening the locking bolts of the slider, the distance between the upper plate and the fixed base plate can be easily adjusted, thereby adapting to the needs of airtightness testing of massage airbags of different sizes and expansion heights. This achieves "one fixture for multiple uses" and significantly improves the versatility of the tooling.

[0014] 2. The present invention provides a fixture for testing a seat massage airbag, which facilitates the application of load: when conducting an airtightness test, a standard counterweight of corresponding weight can be placed directly on the upper surface of the upper plate according to standard requirements, which can conveniently achieve a fixed load test on the airbag and simulate its real working conditions.

[0015] 3. The present invention provides a fixture for testing seat massage airbags, which has reliable locking and is suitable for burst testing: When conducting burst testing, after adjusting the upper plate to press the airbag tightly (or leaving a gap according to standard requirements), tighten the locking bolts of all sliders to firmly lock the upper plate on the positioning column, forming a rigid closed space, which can effectively withstand the high pressure generated when the airbag bursts and ensure test safety.

[0016] 4. The present invention provides a fixture for testing a seat massage airbag, which is sturdy and durable: the all-metal structure design ensures that the fixture has sufficient mechanical strength and stability, can withstand long-term and repeated test operations, especially the repeated impact of the burst test, and has a long service life.

[0026] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 4 , Figure 1 This is a perspective view of an application example of this utility model. Figure 2 This is the front view of an application example of this utility model. Figure 3 This is a top view of an application example of this utility model. Figure 4This is a perspective view of the slider in an application example of this utility model. This utility model provides a fixture for testing seat massage airbags, including a base plate 1, positioning posts 2, sliders 3, and an upper plate 4. The base plate 1 and upper plate 4 are preferably square metal plates. Four cylindrical metal positioning posts 2 are vertically arranged at the four corners of the base plate 1, forming the supporting and guiding frame of the entire fixture. A slider 3 with a locking function slides on each positioning post 2. The upper plate 4 is fixedly connected to the slider 3. The upper plate 4 is parallel to and opposite to the base plate 1. The seat massage airbag to be tested is placed between the base plate 1 and the upper plate 4. The surface area of ​​the upper plate 4 is larger than the horizontal projected area of ​​the seat massage airbag to be tested, ensuring effective coverage and restriction of the airbag.

[0028] The slider 3 includes a locking bearing 31, a collar 32, a locking bolt 33, and a handle 34. The locking bearing 31 is sleeved on the positioning post 2. The locking bearing 31 has multiple sets of ball bearings (not shown) inside for sliding up and down. The collar 32 is connected to the locking bearing 31. The locking bolt 33 is located on the collar 32 for positioning. The handle 34 is connected to the locking bolt 33. When the locking bolt 33 is tightened, the end of the locking bolt 33 presses against the surface of the positioning post 2, generating a huge frictional force, which locks the slider 3 in the current position. When the locking bolt 33 is loosened, the frictional force disappears, and the upper plate 4 can be pushed by hand to make all the sliders 3 slide up and down synchronously along the positioning post 2, thereby changing the distance between the upper plate 4 and the fixed base plate 1 and adjusting it to the required height.

[0029] The following will refer to Figures 1 to 4 The working principle of this utility model will be explained.

[0030] When conducting the airtightness test, first place the massage air bag to be tested on the fixed base plate 1, then loosen the locking bolt 33, adjust the upper plate 4 to the height required by the standard (or make the upper plate 4 lightly touch the air bag), and finally place a counterweight of the specified weight on the upper surface of the upper plate 4 to start the test.

[0031] When conducting the burst test, the gas bag is first placed on the fixed base plate 1, and the upper plate 4 is adjusted to the predetermined position (usually by pressing the gas bag tightly or leaving a very small gap). Then, the locking bolts 33 on all the sliders 3 are tightened to ensure that the upper plate 4 is completely locked, and then the burst pressure test is carried out.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
