Description

Technical Field

[0001] This utility model relates to the field of EMB pedal simulator testing technology, and in particular to a pedal simulator testing fixture. Background Technology

[0002] With the development of automotive braking systems to the EMB (Electromechanical Braking) stage, pedal simulators were completely decoupled from the rest of the system, with only control lines connecting them. However, pedal simulators exist in two types: integrated (where the pedal simulator and brake pedal are integrated) and non-integrated (where only the pedal simulator is present, excluding the brake pedal). These two types differ significantly in size and shape, causing considerable inconvenience to the design of testing fixtures and equipment.

[0003] To improve installation efficiency and equipment compatibility, further reduce costs, and increase equipment utilization, this utility model designs a set of test fixtures that can be compatible with both integrated and non-integrated pedal simulators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pedal simulator testing fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pedal simulator testing fixture includes a first mounting plate, mounting rods fixed at the four corners of the bottom outer wall of the first mounting plate, a second mounting plate fixed at the bottom outer wall of the mounting rods, extension rods fixed at the four corners of the bottom outer wall of the second mounting plate, a third mounting plate fixed at the bottom outer wall of the extension rods, and an electric telescopic rod fixed at the top outer wall of the first mounting plate. The output shaft of the electric telescopic rod passes through the top outer wall of the first mounting plate, and a push rod is fixed to the output shaft of the electric telescopic rod. The push rod has an internal threaded hole at its bottom outer wall.

[0007] As a further embodiment of this utility model: the inner wall of the internal threaded hole is connected to a second threaded rod by a thread, and a quick-change push head is fixed to the outer wall of the bottom of the second threaded rod.

[0008] As a further improvement of this utility model: a connecting rod is fixed to the inner wall of the quick-change push head, and a bearing is provided on the outer wall of the connecting rod.

[0009] As a further embodiment of this utility model: the inner wall of the internal threaded hole is connected to a first threaded rod by a thread, and an adjusting fork pusher is fixed to the outer wall of the first threaded rod.

[0010] As a further embodiment of this utility model: a mounting block is fixed to the outer wall of the second mounting plate, and a non-integrated pedal is fixed to the outer wall of the mounting block.

[0011] As a further improvement of this utility model, an integrated pedal is fixed to the top outer wall of the third mounting plate by threads.

[0012] As a further improvement of this utility model: a reinforcing angle iron is fixed to the outer wall of the mounting rod, and the bottom outer wall of the reinforcing angle iron is fixed to the top outer wall of the second mounting plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Staff can replace the corresponding adjusting fork pusher and quick-change pusher with threads according to the experimental testing needs, so that the testing fixture can accurately test integrated and non-integrated pedals; reinforcing the angle iron can improve the stability of the overall structure of the mounting rod and the second mounting plate, thereby improving the overall stability of the testing fixture during operation.

[0015] 2. During testing, the integrated pedal requires the push rod to directly push the pedal to reciprocate. The second threaded rod on the outer wall of the quick-change push head is threaded onto the internal threaded hole at the bottom of the push rod. The thread allows for easy replacement of the quick-change push head. At the same time, the bearing on the connecting rod on the inner wall of the quick-change push head can effectively reduce the friction between the contact surface of the quick-change push head and the integrated pedal, thereby improving the accuracy of the integrated pedal test.

[0016] 3. The non-integrated pedal and the pedal are separate. Therefore, the non-integrated pedal does not have a brake pedal when it is tested. The non-integrated pedal can be installed on the mounting block by mounting bolts. The mounting block is installed on the second mounting plate. Since the non-integrated pedal does not have a brake pedal, the push rod can directly push the pedal simulator to reciprocate through the adjusting fork push head. Attached Figure Description

[0025] Example 1

[0026] A pedal simulator testing fixture, such as Figure 1-3 As shown, the system includes a first mounting plate 1, mounting rods 2 are fixed at the four corners of the bottom outer wall of the first mounting plate 1, a second mounting plate 7 is fixed at the bottom outer wall of the mounting rods 2, extension rods 4 are fixed at the four corners of the bottom outer wall of the second mounting plate 7, a third mounting plate 6 is fixed at the bottom outer wall of the extension rods 4, an electric telescopic rod 11 is fixed at the top outer wall of the first mounting plate 1, the output shaft of the electric telescopic rod 11 passes through the top outer wall of the first mounting plate 1, a push rod 16 is fixed at the output shaft of the electric telescopic rod 11, and an internal threaded hole 17 is opened on the bottom outer wall of the push rod 16.

[0027] The inner wall of the internal threaded hole 17 is connected to a second threaded rod 15 by a thread, and a quick-change push head 12 is fixed to the bottom outer wall of the second threaded rod 15.

[0028] A connecting rod 18 is fixed to the inner wall of the quick-change push head 12, and a bearing 13 is provided on the outer wall of the connecting rod 18;

[0029] The inner wall of the internal threaded hole 17 is connected to the first threaded rod 10 by thread, and the outer wall of the first threaded rod 10 is fixed with the adjusting fork pusher 9.

[0030] The second mounting plate 7 has a mounting block 3 fixed to its outer wall, and a non-integrated pedal 5 is fixed to the outer wall of the mounting block 3;

[0031] An integrated pedal 14 is fixed to the top outer wall of the third mounting plate 6 by threads.

[0032] First, the integrated pedal 14 is installed on the third mounting plate 6 using mounting bolts. The third mounting plate 6 is then installed on the second mounting plate 7 via an extension rod 4. The entire fixture is then installed on the mounting rod 2. During testing, the integrated pedal 14 requires the push rod 16 to directly push the pedal to reciprocate. The second threaded rod 15 on the outer wall of the quick-change push head 12 is threaded onto the internal threaded hole 17 at the bottom of the push rod 16. This thread allows for easy replacement of the quick-change push head 12. Simultaneously, the bearing 13 on the connecting rod 18 on the inner wall of the quick-change push head 12 effectively reduces friction between the contact surfaces of the quick-change push head 12 and the integrated pedal 14, thereby improving the accuracy of the integrated pedal 14 test.

[0033] The non-integrated pedal 5 is separate from the pedal, so the non-integrated pedal 5 does not have a brake pedal when it is tested. The non-integrated pedal 5 can be installed on the mounting block 3 by mounting bolts. The mounting block 3 is installed on the second mounting plate 7. Since the non-integrated pedal 5 does not have a brake pedal, the push rod 16 can directly push the pedal simulator to reciprocate through the adjusting fork push head 9. The staff can replace the corresponding adjusting fork push head 9 and quick-change push head 12 by thread according to the experimental test needs, so that the test fixture can accurately test the integrated pedal 14 and the non-integrated pedal 5.

[0034] like Figure 1-3 As shown, a reinforcing angle iron 8 is fixed to the outer wall of the mounting rod 2, and the bottom outer wall of the reinforcing angle iron 8 is fixed to the top outer wall of the second mounting plate 7; the reinforcing angle iron 8 can improve the stability of the overall structure of the mounting rod 2 and the second mounting plate 7, thereby improving the stability of the test fixture as a whole during operation.

[0035] Working principle: First, the integrated pedal 14 is installed on the third mounting plate 6 by mounting bolts. The third mounting plate 6 is installed on the second mounting plate 7 by extension rod 4. The entire fixture is installed on mounting rod 2. During the test, the integrated pedal 14 needs to be pushed by push rod 16 to make reciprocating motion to complete the test. The second threaded rod 15 on the outer wall of the quick-change push head 12 is installed on the internal threaded hole 17 at the bottom of push rod 16 by threads. The quick-change push head 12 can be easily replaced by threads.

[0036] The non-integrated pedal 5 is separate from the pedal. Therefore, the non-integrated pedal 5 does not have a brake pedal when it is tested. The non-integrated pedal 5 can be installed on the mounting block 3 by mounting bolts. The mounting block 3 is installed on the second mounting plate 7. Since the non-integrated pedal 5 does not have a brake pedal, the push rod 16 can directly push the pedal simulator to reciprocate through the adjusting fork push head 9.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
