Description

Technical Field

[0001] The utility model belongs to the technical field of seat airbag ECU detection, and in particular relates to a seat airbag ECU testing device. Background Art

[0002] The airbag ECU in a car refers to a module that controls the change of airbag gas. For example, the airbag ECU can quickly inflate the airbag. However, the airbag ECU controls the inflation of the airbag by detonating the airbag, such as the door lock safety performance test system in a car collision test in the publication (announcement) No. CN116879649A.

[0003] At present, airbags in cars are no longer limited to airbags used to protect passengers. Airbags are also installed in car seats, and multiple airbags are installed. By inflating and deflating these airbags, better support and massage functions can be achieved. To control these airbags, a seat airbag ECU is needed. The seat airbag ECU is an integrated module that can be connected to the air pump and airbag through the main interface and the auxiliary interface respectively, and then by controlling the switch of the internal air valve, the pumped gas flows into the corresponding airbag, which is equivalent to the role of transferring gas between the air pump and the airbag.

[0004] Before the seat airbag ECU is assembled with the seat, it needs to be tested for air tightness and ECU function. Currently, there is no special device for performing such test on the seat airbag ECU. Manual testing requires manually inserting multiple air pipes into the main joint and the auxiliary joint for air tightness test, unplugging the air pipes after the air tightness test, and inserting the test plug into the port for ECU function test, and unplugging the plug after the ECU function test. Therefore, the test efficiency is limited and it is difficult to cope with the situation of a large number of tests. For this reason, the present application proposes a seat airbag ECU testing device. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments of ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0030] Example

It should be noted that the number of gas detection sub-joints 300 in the figure is only for reference and does not represent the actual number. The gas detection main joint 200 is a two-way joint, one end of which is connected to the gas source and the other end is connected to the main interface of the ECU; the gas detection sub-joint 300 is a two-way joint, one end is externally connected and the other end is connected to the sub-interface of the ECU. After the gas detection main joint 200 and the gas detection sub-joint 300 are connected to the seat airbag ECU, the seat airbag ECU is subjected to an airtight test according to the set test procedure. The test procedure and the airtight test method are prior art and do not belong to the protection scope of this application. After the test is completed, the air test main connector 200 and the air test auxiliary connector 300 are retracted, and the seat air bag ECU is released, and the seat air bag ECU can be taken out.

[0038] like Figure 6 As shown, the power measurement horizontal limit assembly 920 may include: a power measurement positioning plate 921, which is arranged on the surface of the power measurement limit platform 910; by setting the power measurement positioning plate 921, it can be aligned with a side of the seat airbag ECU setting port, thereby ensuring that the seat airbag ECU is placed on the power measurement limit platform 910 with the correct orientation. A power measurement limit protrusion 922 is arranged on the surface of the power measurement limit platform 910 and is spaced apart from the power measurement positioning plate 921, so as to clamp the ECU when the ECU is aligned with the power measurement positioning plate 921. In at least one embodiment, as Figure 6 and Figure 3 As shown, the function test limit convex part 922 includes a plurality of columnar convex parts and two block convex parts. When the seat airbag ECU is placed on the function test limit platform 910 in the correct orientation, it can be just caught by these function test limit convex parts 922, so as to be limited in the horizontal direction. When the top surface of the horizontally limited seat airbag ECU is abutted by the vertical limit plate 950, it is fixed.

A test plug 800, which is arranged on the transition plate 940, is suitable for being inserted into the port of the ECU when the vertical limit plate 950 is driven to abut against the top surface of the ECU.

[0040] like Figure 6 As shown, the power measurement substrate 520 is disposed on a slider of the power measurement guide rail 530 to ensure that the power measurement driving member 510 drives the power measurement substrate 520 to move in an accurate direction.

It should be noted that the number of power measurement auxiliary connectors 700 in the figure is only for illustration and does not represent the actual number. The power measurement main connector 600 is a two-way connector, one end of which is connected to the air source and the other end is connected to the main interface of the ECU; the power measurement auxiliary connector 700 is a two-way connector, one end of which is externally connected and the other end is connected to the auxiliary interface of the ECU.

The tester puts the first seat airbag ECU into the airtight test fixing assembly 400 on the bottom layer, and immediately puts the second seat airbag ECU into the airtight test fixing assembly 400 on the second layer, and then immediately puts the third seat airbag ECU into the functional test fixing assembly 900 on the bottom layer, and then immediately puts the fourth seat airbag ECU into the functional test fixing assembly 900 on the second layer, and so on. The cycle is repeated to reduce waiting time and further improve test efficiency.
