Description

Technical Field

[0001] This utility model relates to the field of impact testing of electronic water pumps, and in particular to a fixing fixture for impact testing of electronic water pumps. Background Technology

[0002] With the rapid development of new energy vehicles such as pure electric vehicles and hybrid vehicles, electronic water pumps have been widely used. Compared with traditional mechanical water pumps, electronic water pumps are driven by electric motors or other electric drive devices, converting electrical energy into mechanical energy to propel water or other liquids. They have advantages such as small size and automatic speed adjustment according to engine power conditions, making them a key component of new energy vehicles. However, electronic water pumps are subject to various mechanical stresses during operation, such as vibration and impact. In particular, during vehicle operation, road bumps, engine vibration, and even vehicle collisions can impact the water pump, potentially causing damage to the pump's mechanical structure and a decrease in sealing performance. Therefore, impact testing of electronic water pumps is an essential test.

[0003] Currently, in existing technologies, the fixtures on impact testing platforms are arranged in a cubic shape, such as... Figure 1 and Figure 2 As shown, this fixture is difficult and costly to manufacture. During testing, it is used to measure the impacts on the electric water pump in the ±X-axis, ±Y-axis, and +Z-axis directions, but it cannot simulate the impact test of the electric water pump under vehicle rollover conditions. Utility Model Content

[0005] This utility model proposes a fixing fixture for impact testing of electronic water pumps, including a base mounted on an impact testing platform, a first fixing part and a second fixing part for mounting the electronic water pump to be tested, the first fixing part being fixed longitudinally on the base, the second fixing part being adjustablely mounted on the first fixing part, and the second fixing part being perpendicular to the electronic water pump mounting surface on the first fixing part.

[0006] Preferably, the first fixing part has a plurality of first through holes for installing an electronic water pump or connecting to the second fixing part, and the first through holes are arranged in an array.

[0007] Preferably, the second fixing part includes a mounting plate and a fixing plate, the fixing plate being vertically fixed on the mounting plate; the fixing plate has a second through hole corresponding to the first through hole for connecting the first fixing part; the mounting plate has a plurality of third through holes for mounting an electronic water pump.

[0008] As described above, the fixing fixture for impact testing of electronic water pumps disclosed in this utility model has the following beneficial effects:

[0009] This invention achieves omnidirectional impact testing of the electronic water pump by adjusting the second fixing part to the first fixing part, with the electronic water pump mounting surface on the second fixing part perpendicular to the electronic water pump mounting surface on the first fixing part.

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0021] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0022] like Figures 1 to 7 As shown, an embodiment of a fixture for impact testing of an electronic water pump includes a base 100 mounted on an impact testing platform, a first fixing part 200 and a second fixing part 300 for mounting the electronic water pump under test. The first fixing part 200 is fixed longitudinally to the base 100, and this fixing method includes, but is not limited to, welding. The second fixing part 300 is adjustablely disposed on the first fixing part 200, and the second fixing part 300 is perpendicular to the electronic water pump mounting surface on the first fixing part 200. The first fixing part 200 and the second fixing part 300 are connected by, but are not limited to, threaded connections. When testing the electronic water pump, the orientation of the first fixing part 200 can be adjusted to perform impact testing on the electronic water pump in all directions (i.e., ±X-axis, ±Y-axis, and ±Z-axis directions). It should be noted that the first fixing part 200 and the second fixing part 300 can be separately mounted on the impact testing platform to fix the electronic water pump.

[0023] In use, when performing impact tests on the electronic water pump in the ±X-axis direction, the base 100 is fixedly mounted to the impact test bench with bolts. Since the first fixing part 200 is fixed to the base 100 longitudinally (i.e., in the Z-axis direction), the test can be started independently using the first fixing part 200. The electronic water pump to be tested is then installed sequentially on the front and back side walls of the first fixing part 200 according to the test sequence. Then, the impact force is applied by driving the impact test platform through the impact test equipment to rapidly descend the first fixing part 200, thereby achieving the impact test on the electronic water pump in the ±X-axis direction.

[0024] When performing an impact test on the electric water pump in the ±Z axis direction, the second fixing part 300 is fixedly connected to the first fixing part 200 in the first posture by bolts (e.g. Figure 3As shown in the diagram, the second fixing part 300 is provided with mounting surfaces for the electronic water pump along the ±Z axis. The electronic water pumps to be tested are installed sequentially on the mounting surfaces of the second fixing part 300 along the ±Z axis in the test sequence. The impact testing equipment drives the impact testing platform to rapidly descend the first fixing part 200 to apply impact force, thereby achieving impact testing of the electronic water pumps in the ±Z axis direction.

[0025] When performing an impact test on the electric water pump along the ±Y axis, adjust the second fixing part 300 to change it from the first posture to the second posture, and then fix the first fixing part 200 to it with bolts (e.g., Figure 7 As shown, the mounting surface of the second fixing part 300 along the ±Z axis direction is changed to the mounting surface along the ±Y axis direction. The electronic water pump under test is installed sequentially on the mounting surface of the second fixing part 300 along the ±Y axis direction according to the test sequence. The impact testing equipment drives the impact testing platform to rapidly descend the first fixing part 200 to apply impact force, so as to realize the impact test of the electronic water pump in the ±Y axis direction.

[0026] In one embodiment, the first fixing part 200 has a plurality of first through holes 210 for mounting an electric water pump or connecting to the second fixing part 300. The first through holes 210 are arranged in an array to improve connection stability. During installation, the electric water pump or the second fixing part 300 can be fixedly connected by bolts through the first through holes 210.

[0027] In one embodiment, the second fixing part 300 includes a mounting plate 310 and a fixing plate 320, with the fixing plate 320 vertically fixed to the mounting plate 310. The fixing plate 320 has a second through hole 321 corresponding to the first through hole 210, which is used to connect to the first fixing part 200. The mounting plate 310 has a plurality of third through holes 311 for mounting an electronic water pump.

[0028] In use, the fixing plate 320 is attached to one side of the first fixing part 200, aligning the second through hole 321 with the first through hole 210. Bolts are then used to fix the fixing plate 320 to the first fixing part 200 sequentially through the first through hole 210 and the second through hole 321. When the posture of the mounting plate 310 needs to be adjusted, the bolts connecting the fixing plate 320 and the first fixing part 200 can be removed. After adjusting the mounting plate 310 from the first posture to the second posture, the fixing plate 320 is then fixed to the first fixing part 200 with bolts. Regardless of whether the impact test of the electronic water pump is performed in the ±Y-axis or ±Z-axis direction, the electronic water pump under test must be mounted on the corresponding mounting surface of the mounting plate 310.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
