Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, the present invention provides a low-temperature start-up performance cyclic testing device for a seat motor, comprising: Base 1; The low temperature test chamber 2 is installed on the base 1. The low temperature test chamber 2 is used to place the motor under test 5 and keep the motor under test 5 at the test temperature. A sleeve is provided on one side of the low temperature test chamber 2, and the output shaft of the motor under test 5 extends out of the low temperature test chamber 2 through the sleeve. The test assembly includes a load unit 3, which includes a magnetic powder brake 31. The magnetic powder brake 31 is mounted on the base 1 and is located outside the low-temperature test chamber 2. The magnetic powder brake 31 is coaxially connected to the output shaft of the motor under test 5.

[0018] In this embodiment, a low-temperature test chamber 2 is set up so that the motor can be placed inside the low-temperature test chamber 2 during the test. The output shaft of the motor under test 5 can be extended out of the chamber and connected to the load unit 3 through the sleeve on one side of the low-temperature test chamber 2, thereby realizing the simulation of the motor's starting performance test in a low-temperature environment and ensuring the authenticity of the motor's various parameters and performance data.

[0019] like Figures 1 to 4 As shown, in one embodiment, the low-temperature test chamber 2 is provided with an installation mechanism, which includes a first mounting base 21 and a second mounting base 22. The first mounting base 21 is connected to the low-temperature test chamber 2, and the second mounting base 22 is used to install the motor under test 5. The motor under test 5 is connected to the first mounting base 21 through the second mounting base 22.

[0020] In this embodiment, the installation mechanism is set up to achieve the effect of quick disassembly and assembly of the motor 5 under test, thereby improving the stability of the test. Specifically, the motor is installed on the second mounting base 22, and then the second mounting base 22 is quickly connected to the first mounting base 21, thereby improving the disassembly and assembly effect of the motor 5 under test.

[0021] like Figures 2 to 4 As shown, in one embodiment, the first mounting base 21 is provided with a first limiting part 211, a limiting member 212, and a quick-release member 213. One end of the limiting member 212 is rotatably connected to the first mounting base 21, and the other end of the limiting member 212 is connected to the first mounting base 21 via the quick-release member 213. The first limiting part 211 and the limiting member 212 together form a limiting area to prevent the second mounting base 22 from moving relative to the first mounting base 21. The second mounting base 22 is installed within the limiting area.

[0022] In this embodiment, the other end of the limiting member 212 is quickly connected to the first mounting base 21 by the quick-release member 213, so that the first limiting part 211 and the limiting member 212 together form a limiting area, thereby achieving the effect of quick assembly and disassembly of the second mounting base 22 and the first mounting base 21.

[0023] Specifically, the second mounting base 22 is a mounting plate, and the motor under test 5 is fixed on the mounting plate by fasteners. The first limiting part 211 is a limiting groove, which limits the periphery of the mounting plate and limits the direction of the mounting plate from the limiting groove by the limiting part 212, so as to prevent the mounting plate from detaching from the limiting groove, thereby achieving the effect of quick assembly and disassembly of the first mounting plate, the second mounting plate and the motor under test 5.

[0024] It should be noted that multiple mounting plates can be configured to install the motor 5 under test separately, thereby achieving the effect of rapid turnover, disassembly and assembly, and testing.

[0025] In one embodiment, the first mounting base 21 has a locked state and an unlocked state; When the first mounting base 21 is in the locked state, the quick-release member 213 is connected to the first mounting base 21 to fix one end of the limiting member 212 connected to the quick-release member 213 to the first mounting base 21, so that the limiting member 212 and the first limiting part 211 together form a limiting area. When the first mounting base 21 is in the unlocked state, the quick-release member 213 disengages from the first mounting base 21, so that the end of the limiting member 212 connected to the quick-release member 213 rotates around the other end to move away from the first mounting base 21, so that the second mounting base 22 can enter the first limiting part 211 or disengage from the first limiting part 211.

[0026] In one embodiment, an electronic control component is also included, which includes a power module mounted on the base 1. The low-temperature test chamber 2 is provided with a through hole, and the motor under test 5 is electrically connected to the power module through the through hole. The power module is used to supply power to the motor under test 5.

[0027] In this embodiment, a power module is installed on the base 1 and placed inside the low-temperature test chamber 2 to ensure test safety. A through hole is provided on the low-temperature test chamber 2 so that the electrical connection wires (i.e., power wires, power cords) of the motor under test inside the low-temperature test chamber 2 can be electrically connected to the power module through the through hole, thereby ensuring that the motor under test 5 can be tested normally.

[0028] The power module can be a socket or a programmable DC power supply.

[0029] As needed, the electronic control components also include a PLC module, which is electrically connected to the magnetic powder brake 31 and the power supply module respectively, thereby enabling real-time adjustment of the load torque of the magnetic powder brake 31 to meet the testing requirements of various scenarios (such as simulating seat resistance curves), and to realize the on / off start / stop control of the motor 5 under test, thereby ensuring the start / stop test work at low temperature.

[0030] like Figure 2 As shown, in one embodiment, a closable material inlet 23 is formed on one side of the low-temperature test chamber 2.

[0031] In this embodiment, the second mounting base 22 and the motor under test 5 can be conveniently removed and placed through the material handling port 23.

[0032] Specifically, a door is provided on the outside of the low temperature test chamber 2. The door is rotatably connected to the low temperature test chamber 2 to block the material inlet 23 or to separate it from the material inlet 23 so that the material inlet 23 is opened when the motor to be tested 5 is replaced; after the replacement is completed, the material inlet 23 is closed.

[0033] like Figures 1 to 2 As shown, in one embodiment, a bearing is installed at the sleeve, and the output shaft of the motor under test 5 is rotatably connected to the sleeve through the bearing.

[0034] In this embodiment, by setting a bearing at the sleeve opening, the test effect of the motor under test 5 is avoided, and the gas temperature of the low temperature test chamber 2 is prevented from exchanging with the external air temperature through the sleeve opening, thereby reducing energy consumption and improving resource utilization.

[0035] like Figures 1 to 2 As shown, in one embodiment, the load unit 3 further includes a speed reducer 32; The test assembly also includes a data acquisition unit, which includes a torque and speed sensor 41. The input terminal of the torque and speed sensor 41 is connected to the motor under test 5. The torque and speed sensor 41 is connected to the magnetic powder brake 31 through a reducer 32.

[0036] In this embodiment, the fluctuation of the magnetic powder brake 31 can be eliminated by setting the speed reducer 32, and the torque data is collected and processed by the torque speed sensor 41 in order to obtain the various performance test results of the motor 5 under test.

[0037] like Figures 1 to 2 As shown, in one embodiment, a third mounting base 6 is also included. The third mounting base 6 is mounted on the base 1. The third mounting base 6 is provided with a first mounting part 61 and a second mounting part 62. The first mounting part 61 is used to mount the magnetic powder brake 31, and the second mounting part 62 is used to mount the speed reducer.

[0038] The third mounting base 6 is connected to the base 1 by fasteners.

[0039] In one embodiment, the data acquisition unit further includes a temperature sensor mounted on the housing of the motor 5 under test, which is used to detect the temperature of the motor 5 under test.

[0040] In this embodiment, by installing a temperature sensor on the motor housing, the temperature of the motor 5 under test can be detected, so as to test the effect at different temperatures.

[0041] In one embodiment, the data acquisition unit further includes a power analyzer connected to the power input side of the motor under test 5, and the power analyzer is used to detect the power parameters of the motor under test 5.

[0042] In this embodiment, a power analyzer is set up and connected to the power input side of the motor under test 5, thereby realizing the changes in the electrical parameters of the motor under test 5 during the test. The electrical parameters include voltage, current, power, etc.

[0043] Depending on the requirements, the test component may also include a data receiving unit, which is electrically or signal-connected to the data acquisition unit to receive the data acquired by the data acquisition unit for subsequent processing.

[0044] Depending on the requirements, the test assembly may also include a data processing unit, which is electrically or signal-connected to the data receiving unit to process the data received by the data receiving unit in order to analyze the performance indicators of the motor, etc.
