Description

Technical Field

[0001] This utility model relates to the field of automotive seat quality inspection, and in particular to a handheld automotive seat memory motor inspection device. Background Technology

[0002] Automotive seat motors come in two types: memory motors and non-memory motors. They are extremely similar in appearance. During assembly on the production line, workers may mistakenly install non-memory motors onto seats requiring memory motors, causing product malfunction. Because memory motors are more expensive than non-memory motors, some suppliers may also mix non-memory motors with memory motors for sale. Current technology distinguishes between memory and non-memory motors by using an oscilloscope and a series rheostat to detect waveform display. However, this method has drawbacks: oscilloscopes are bulky and expensive, allowing only a small number of seats to be sampled for testing, resulting in low efficiency and an inability to significantly ensure product quality stability. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by developing a handheld automotive seat memory motor testing device. The technical solution adopted by this utility model is as follows: a handheld automotive seat memory motor testing device, characterized by comprising a housing 1, a hook 2, a circuit board 12, a voltage comparison module 13, and a battery 16; the housing 1 includes an upper housing 8 and a lower housing 9; the hook 2 is hinged to the lower housing 9; the circuit board 12, the voltage comparison module 13, and the battery 16 are respectively disposed within the housing 1; a toggle switch 3, an indicator light 4, and a buzzer 5 are respectively fixedly disposed on the upper housing 8; a winding frame 15 is disposed within the housing 1; the shaft of the handwheel 7 passes through the side of the lower housing 9 and is fixedly connected to the winding frame 15; a sheathed cable 14... One end of the cable is soldered to the circuit board 12, and the other end passes through the center hole of the winding frame 15 and through the lower housing 9; the sheathed cable 14 is inserted into the junction box 17 at one end outside the outer housing 1 and is connected to three other sheathed cables, the ends of each sheathed cable being connected to the first plug 18, the second plug 19 and the third plug 20 respectively; a charging port 10 is provided on the lower housing 9; anti-slip rubber pads 6 are fixedly pasted on both sides of the lower housing 9; a magnet 11 is fixedly set on the lower part of the lower housing 9; the toggle switch 3, indicator light 4, buzzer 5, circuit board 12, charging port 10, voltage comparison module 13 and battery 16 are electrically connected.

[0004] The advantages of this utility model are as follows: by using a battery-powered voltage comparison module to connect the indicator light and the buzzer, compared with the existing oscilloscope testing device, the size is reduced, the cost is lowered, and it is easy to carry. This allows the device to be used handheld in the seat warehouse for testing, shortening the testing time, increasing the testing range, and effectively improving the consistency of product quality.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0013] like Figures 1 to 4As shown, this utility model includes: a housing 1, a hook 2, a circuit board 12, a voltage comparison module 13, and a battery 16; the housing 1 includes an upper housing 8 and a lower housing 9; the hook 2 is hinged to the lower housing 9; the circuit board 12, the voltage comparison module 13, and the battery 16 are respectively disposed inside the housing 1; a toggle switch 3, an indicator light 4, and a buzzer 5 are respectively fixedly disposed on the upper housing 8; a winding frame 15 is disposed inside the housing 1; the shaft of the handwheel 7 passes through the side of the lower housing 9 and is fixedly connected to the winding frame 15; one end of the sheathed wire 14 is soldered to the circuit board 12. The other end of the cable passes through the center hole of the winding frame 15 and through the lower housing 9; the sheathed cable 14 is inserted into the junction box 17 at one end outside the outer housing 1 and connected to the other three sheathed cables, the ends of each sheathed cable being connected to the first plug 18, the second plug 19 and the third plug 20 respectively; a charging port 10 is provided on the lower housing 9; anti-slip rubber pads 6 are fixedly pasted on both sides of the lower housing 9; a magnet 11 is fixedly set on the lower part of the lower housing 9; the toggle switch 3, indicator light 4, buzzer 5, circuit board 12, charging port 10, voltage comparison module 13 and battery 16 are electrically connected.

[0014] Figure 5 This is a circuit diagram of the electronic component of this utility model.

[0015] Memory motors have two more pins than non-memory motors. One end of these pins connects to the inside of the motor, and the other end connects to the dual-channel voltage comparison module. A 180-ohm resistor is connected in series with these pins. An indicator light and a buzzer are connected to pins - and 5 of the voltage comparison module. It should be noted that some non-memory motors have the same number of pins as memory motors; therefore, the number of pins is not the standard for distinguishing between memory and non-memory motors. Based on the operating characteristics of the voltage comparison module, the internal potentiometer needs to be adjusted initially. After adjustment, if the indicator light illuminates and the buzzer sounds an alarm, it is ultimately identified as a memory motor; otherwise, it is identified as a non-memory motor. The voltage between the CH1+ and - pins of the dual-channel voltage comparison module is the reference voltage. Generally, the reference voltage can be adjusted to between 9.5 and 10V by adjusting potentiometer 1. If potentiometer 1 is damaged, potentiometer 2 can be used for adjustment; both potentiometers have the same function.

[0016] In specific operations, such as Figure 6 As shown, the worker first hangs the device on the headrest rod 21 on the seat back 22 using hook 2. If the seat back to be tested does not have a headrest rod 21, the device can be magnetically attached to the seat metal frame using magnet 11 at the rear of the lower housing 9. The worker rotates handwheel 7 to release the sheathed wire 14 from the housing 1. After reaching the required length, the worker selects one of the first plug 18, the second plug 19, or the third plug 20 and inserts it into the motor socket of the seat to be tested. Figure 6 Taking the testing of the backrest motor 23 as an example, the testing principle for other motors is the same. Typically, three motors need to be tested on a single seat; therefore, the first plug 18, the second plug 19, and the third plug 20 of this device correspond to the different shaped connectors of these three motors. The worker inserts the first plug 18 into the connector of the backrest motor 23, turns on the toggle switch 3, and the testing process begins. According to the principle described above, if the backrest motor 23 is a memory motor, the indicator light 4 will illuminate, and the buzzer 5 will sound an alarm, confirming that the backrest motor 23 is indeed a memory motor.

[0017] If a non-memory motor is detected, the worker will mark the seat so that it can be replaced with a memory motor in the future.

[0018] After the inspection is completed, the worker rotates the handwheel in the opposite direction to retract the sheathed wire. The sheathed wire is wound around the winding frame, leaving only the junction box, a shorter sheathed wire, and the plug outside the outer casing. This makes the device easy to carry and store, and effectively prevents the sheathed wire from getting tangled or damaged.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of the present utility model.
