Description

Technical Field

[0001] The utility model relates to the technical field of seat motor detection, in particular to a seat motor noise detection device. Background Art

[0002] Seat motor testing technology encompasses multiple disciplines, including mechanical engineering, electronic engineering, and control systems. It is primarily used in seat adjustment systems in industries such as automotive, aviation, and home furnishings. With technological advancements and continuous innovation, the importance of seat motor testing is growing. As market demands for product quality increase, various industries are developing standards and specifications to ensure that seat motors meet performance, safety, and environmental requirements. Noise levels are often a key metric for evaluating equipment performance. High noise levels can indicate mechanical failure, wear, or design flaws. Therefore, noise testing can identify potential issues promptly, ensuring product quality standards and ensuring product consistency across batches.

[0003] Among many existing technologies, Chinese patent application CN207318081U discloses a car seat motor loading test device, in which more than two connecting pair fixing seats are distributed on the fixed base, and a connecting pair is hinged on a connecting pair fixing seat, and each connecting pair is hinged to the connecting base. One of the connecting pairs is provided with a gear rotating pair on the connecting base side, and a seat motor locating pin is provided on the connecting base next to the gear rotating pair. A clamping cylinder is installed on the connecting base, and a clamping head for positioning and clamping the seat motor is installed on the clamping cylinder. A weight box for carrying weights is provided on the connecting base.

[0004] However, this patent application first pre-positions the car seat motor to the connecting base through a positioning pin, and at the same time places weights in a weight box to simulate a load, and then starts the seat motor, and judges whether the seat motor product is qualified by manually listening to the noise during the movement. The simulated load during the detection of this patent application is fixed, and the load cannot be increased in real time. It is necessary to add weights to the weight box multiple times to detect whether the seat motor is operating within the designed load range. The process is cumbersome and unsafe, and also increases the detection time. In addition, the error of judging by manually listening to the noise is large, and data under different loads cannot be obtained to analyze the performance of the seat motor under different loads. It is impossible to evaluate the noise impact and work efficiency of the seat motor based on the test results under different loads to determine whether improvement or maintenance is needed.

[0005] Based on this, the present invention designs a seat motor noise detection device to solve the above problem. Utility Model Content

Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figures 1-6A seat motor noise detection device includes a mounting base 1, a test assembly 2 for fixing a seat motor 4 and detecting the noise of the seat motor 4 under load is mounted on the mounting base 1, a counterweight switching assembly 3 for providing different weights to the test assembly 2 to simulate different loads is mounted on the mounting base 1, and the test assembly 2 is connected to the seat motor 4;

[0030] The counterweight switching assembly 3 includes a counterweight block 31, a cone 32, and a switching assembly 33. The counterweight block 31 has multiple groups of equal spacing arranged vertically. The cone 32 is connected to the test assembly 2. The inner wall of the cone 32 is in contact with the outer wall of the counterweight block 31. The counterweight block 31 is connected to the switching assembly 33.

[0031] When the present invention is used, the seat motor 4 is mounted on the test assembly 2 and fixed by the test assembly 2. The seat motor 4 is started and the test assembly 2 simulates the use scenario and is tested by the test assembly 2. Then the switching assembly 33 drives the counterweight 31 to fall into the cone 32 to gradually increase the load. During the seat motor 4 detection process, the test assembly 2 simulates the use scenario and there will be a horizontal displacement of the cone 32 to prevent the counterweight 31 from falling off. The cone 32 realizes a gradual increase in load to facilitate the detection of the operating noise of the seat motor 4 under different loads, ensuring that the seat motor 4 can work normally under the rated load and there is no excessive noise. By analyzing the performance of the seat motor 4 under different loads, it can be determined whether it is operating within the design range. According to the test results under different loads, the noise impact and work efficiency of the seat motor 4 are evaluated to determine whether improvement or maintenance is needed.

The second limiting rods 293 are arranged in three groups in a circular array and are plugged into the upper limit holes of the seat motor 4. The front end of the second limiting rods 293 is fixedly connected to the rear end surface of the mounting plate 292, and the rear end surface of the mounting plate 292 is in contact with the front end surface of the seat motor 4.

[0036] When the present invention is used, the shaft at the output end of the seat motor 4 is inserted into the groove provided on the connecting block 25, and the gear at the output end of the seat motor 4 is meshed with the sector tooth 26, and then the driving cylinder 291 is started, and the driving cylinder 291 drives the mounting plate 292, and the mounting plate 292 drives the second limiting rod 293 to be inserted into the upper limit hole of the seat motor 4 to limit the angle of the seat motor 4, and then the mounting plate 292 presses the seat motor 4 against the seat motor 4 to stabilize the seat motor 4 in the test position. When the seat motor 4 is inserted, the auxiliary rod 24 is used to support the right end of the seat motor 4 for quick movement. The seat motor 4 is placed at a corresponding angle so that the second limit rod 293 is accurately engaged. After the limit is completed, the seat motor 4 is started.

[0040] When the present invention is in use, the reduction motor 337 is started, and the reduction motor 337 drives the tightening wheel 335 to tighten or release the steel rope 331. When a load needs to be applied, the reduction motor 337 drives the tightening wheel 335 to release the steel rope 331, and the left end of the steel rope 331 drops.
