Description

Technical Field

[0001] The utility model relates to the field of push rod motor testing equipment, in particular to a push rod motor life testing device. Background Art

[0002] The automatic door opening technology in a steam oven is a technology that uses a push rod motor to drive the oven door to open. After the food in the oven is heated, the oven door can be automatically opened for the user to take out the food, eliminating the step of manually opening the oven door. The push rod motor is the main equipment that can achieve automatic door opening. Therefore, the performance of the push rod motor needs to be tested when the oven is assembled. During the test, the thrust performance of the push rod motor is emphasized. However, currently only a single push rod motor is usually tested, and the detection efficiency is low.

[0003] In response to the above problems, the prior art, such as a Chinese utility model patent with patent number ZL202021266729.0 (publication number CN212932879U) "A push rod motor life test device" discloses a test device that can test the service life of multiple push rod motors at the same time. In the device, multiple push-pull force simulation tooling is provided and connected one-to-one with the push rod motors to be tested. The resistance encountered by the push rod motor when pushing the push rod is adjusted by adjusting the compression degree of the spring. The test device in this patent can test multiple push rod motors at the same time, thereby improving the test efficiency. However, when setting up multiple push-pull force simulation tooling, it is necessary to ensure that the movements of each tooling do not interfere with each other, so a certain distance needs to be maintained between each other, which makes the overall space larger and the space utilization rate is low.

When there are multiple push rod motors and they need to be applied to the steam oven, the test device needs to have the function of being able to test multiple push rod motors at the same time. Therefore, it will be beneficial to provide a push rod motor life test device with high test efficiency. The structure of the push rod motor life test device will be described below:

[0034] See also Figure 1 to Figure 2 The push rod motor life test device includes a bottom plate 1, a first fixed plate 2, a first suction generating member 3, a second fixed plate 4, a second suction generating member 5, a trigger member 6, a first counter 7 and a second counter 8, wherein the first fixed plate 2 is arranged on the bottom plate 1, the first suction generating member 3 is arranged on the first fixed plate 2, the second fixed plate 4 is arranged on the bottom plate 1 and has a spacing with the first fixed plate 2, the second suction generating member 5 is arranged on the second fixed plate 4, and the trigger member 6 can be moved back and forth between the first fixed plate 2 and the second fixed plate 4, and can cooperate with the first suction generating member 3 and the second suction generating member 5 by suction; the first counter 7 is used to record the number of times the trigger member 6 is away from the first fixed plate 2; the second counter 8 is used to record the number of times the trigger member 6 is away from the second fixed plate 4. The shells of the first counter 7 and the second counter 8 are both made of high temperature resistant materials, so that the push rod motor life test device can be tested in a high temperature environment to simulate the high temperature environment inside the steam oven; the first push rod motor is installed on the outside of the first fixed plate 2, and the second push rod motor is installed on the outside of the second fixed plate 4.

[0035] The first suction force generating member 3 is a magnet, the first fixed plate 2 and the second fixed plate 4 are both non-magnetic materials, and the trigger member 6 is an iron material that can be magnetically attracted to the magnet. The second suction force generating member 5 is also a magnet, and the first fixed plate 2 and the second fixed plate 4 are both made of aluminum alloy.

[0036] The first fixed plate 2 is provided with a plurality of mounting grooves 21 on one side close to the trigger member 6, and the first suction generating member 3 has a plurality of mounting grooves 21 disposed in the mounting grooves 21. The provision of the plurality of mounting grooves 21 allows the user to adjust the suction between the first suction generating member 3 and the trigger member 6 by controlling the number of the first suction generating members 3 in the mounting grooves 21, which facilitates the user to simulate the door pushing force of the steam oven. Similarly, the second fixed plate 4 is also provided with a plurality of mounting grooves 21 on one side close to the trigger member 6, and the second suction generating member 5 has a plurality of mounting grooves 21 disposed in the mounting grooves 21.

A positioning groove 22 is recessed on the side of the first fixed plate 2 or the second fixed plate 4 opposite to the limit block 421, and the limit block 421 is adapted to and horizontally faces the positioning groove 22. The matching relationship between the limit block 421 and the positioning groove 22 allows the trigger member 6 to maintain a vertical posture every time it moves between the first fixed plate 2 and the second fixed plate 4, preventing the trigger member 6 from being tilted when the posture moves.

[0040] A first support block 11 for mounting a push rod motor is provided on the bottom plate 1.
