Description

Technical Field

[0001] This invention relates to the technical field of slide rail spring structures for motor loads, and particularly to a slide rail spring structure for motor loads. Background Technology

[0002] In the production process of electronic products, ensuring the quality of electronic products is of paramount importance. The quality of electronic products directly affects their sales volume. Therefore, functional testing of electronic products must be carried out during the production process. In the existing micro motor testing, most methods involve adding weights to the motor under test or placing a counterweight motor at the motor load end. This design results in an overall larger longitudinal dimension, increased site costs, and, from the perspective of testing, additional noise impacts beyond the noise generated by the motor itself.

[0003] Chinese patent CN214795116U discloses a noise testing device for a micro motor under load, comprising a hysteresis brake, a base, and a connecting shaft. One end of the base has a groove, and the hysteresis brake is disposed in the groove. The other end of the base has a motor. The base also has a channel, one end of which communicates with the groove, and the other end of which penetrates the end face of the base. The connecting shaft is disposed in the channel, with one end connected to the hysteresis brake and the other end connected to the motor. The test motor is connected to the hysteresis brake through a coupling and the connecting shaft, thereby realizing hysteresis load and conducting noise testing. However, this structure is installed and fixed longitudinally, requiring a lot of space in the site. Moreover, the hysteresis brake is expensive, and the cost for large-scale multi-line testing is large, resulting in low practical application effectiveness. Summary of the Invention

[0006] Furthermore, the load module includes a limiting component, a slide rail component, and a load component. The limiting component is fixedly connected to the flip plate, the slide rail component slides relative to the flip plate, and the load component is fixedly connected to the slide rail component and connected to the output end of the test motor. The limiting component and the slide rail component are mutually limiting and cooperating.

[0009] Furthermore, the slide rail assembly includes an X-axis slide rail, two sets of Y-axis slide rails, and a connecting plate. The two sets of Y-axis slide rails are disposed on the flip plate, and the X-axis slide rails are disposed below the connecting plate. Both ends of the connecting plate are provided with first sliders, and a plurality of first sliders are corresponding to slide and engage with the Y-axis slide rails. The load module is in sliding engagement with the X-axis slide rails.

[0010] Furthermore, the connecting plate is provided with a plurality of positioning blocks, and the flip plate is provided with locking components that limit and cooperate with the plurality of positioning blocks.

[0011] Furthermore, the load assembly includes two sets of fixing blocks, two sets of fixing rings, a rotating shaft, and a transmission component. The two sets of fixing blocks are fixedly connected to the connecting plate. The two sets of fixing rings are correspondingly sleeved at both ends of the rotating shaft, and both ends of the rotating shaft are respectively fixedly connected to the two sets of fixing rings.

[0021] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a fixed plate 1, a base 2, a flip plate 3, and a load module 4. The base 2 is disposed on the fixed plate 1, the flip plate 3 is movably connected to the base 2, the load module 4 is disposed on the flip plate 3, the flip plate 3 is press-fitted with the test motor, and the load module 4 is snap-fitted with the output end of the test motor. The fixed plate 1 is provided with a plurality of positioning pins, which are corresponding to and guide the test motor. The base 2 is provided with a rotating lug, through which a connecting rod is inserted. The flip plate 3 is connected in series with the connecting rod and rotates around the rotating lug. The flip plate 3 is provided with a buckle. The device features a locking block that engages with a latch. During testing, the latch locks with the locking block, pressing the test motor firmly. When inserting or removing the motor, pressing the latch releases it from the locking block, allowing the flip plate 3 to flip open. The flip plate 3 also has several positioning posts made of resin, offering good wear resistance and preventing scratches on the motor's surface. Springs and guide posts connect the positioning posts to the flip plate 3, allowing for some floating during pressing and effectively preventing rigid pressure from damaging the motor's surface. When the flip plate 3 locks, the positioning posts float and press the test motor firmly, achieving Z-axis positioning and fixation. The device employs a purely mechanical flip-top structure. The flip plate 3 opens and locks around the base 2, and the folding flip clamps and fixes the test motor, reducing the overall longitudinal length and improving space utilization. The structure is compact and efficient. The positioning posts and pins guide, position, and press the test motor, further improving installation efficiency. The floating positioning posts also provide a certain amount of buffering, effectively preventing excessive downward pressure from damaging the test motor's surface.

[0022] like Figure 2As shown, in this embodiment, the load module 4 includes a limiting component 41, a slide rail component 42, and a load component 43. The limiting component 41 is fixedly connected to the flip plate 3, the slide rail component 42 slides relative to the flip plate 3, and the load component 43 is fixedly connected to the slide rail component 42 and connected to the output end of the test motor. The limiting component 41 and the slide rail component 42 are mutually limiting.

[0023] like Figure 3 As shown, in this embodiment, the limiting component 41 includes at least two sets of first limiting blocks 411 and at least two sets of second limiting blocks 412. A plurality of first limiting blocks 411 are disposed on one side of the flip plate 3, and a plurality of second limiting blocks 412 are correspondingly disposed opposite to and fixedly connected to the flip plate 3. Both the first limiting blocks 411 and the second limiting blocks 412 engage with the slide rail assembly 42 for limiting. Both the first and second limiting components are L-shaped structures and are fixed to the flip plate 3 by screws. By using the first limiting blocks 411 and the second limiting blocks 412 to rigidly limit the slide rail assembly 42, the slide rail assembly 42 can slide between the first limiting blocks 411 and the second limiting blocks 412. The adjustable distance is controllable and effective, and it is compatible with test motors of different sizes, exhibiting good compatibility.

[0024] In this embodiment, both the first limiting block 411 and the second limiting block 412 are provided with a plurality of magnetic elements 413. The plurality of magnetic elements 413 are magnetically engaged with the slide rail assembly 42. The magnetic elements 413 on the first limiting block 411 and the magnetic elements 413 on the slide rail assembly 42 repel each other, while the magnetic elements 413 on the second limiting block 412 and the magnetic elements 413 on the slide rail assembly 42 attract each other. The magnetic elements 413 on the first limiting block 411, the second limiting block 412 and the slide rail assembly 42 are all permanent magnets. The structure of the magnetic elements 413 guides and positions the slide rail assembly 42 during movement, so that the slide rail assembly 42 always maintains a magnetic force close to the second limiting block 412, preventing the transmission component 434 from disengaging from the output end of the test motor during movement.

[0025] like Figure 4As shown, in this embodiment, the slide rail assembly 42 includes an X-axis slide rail 421, two sets of Y-axis slide rails 422, and a connecting plate 423. The two sets of Y-axis slide rails 422 are disposed on the flip plate 3, and the X-axis slide rail 421 is disposed below the connecting plate 423. Each end of the connecting plate 423 is provided with a first slider 424, and several first sliders 424 are slidably engaged with the Y-axis slide rails 422. The load module 4 is slidably engaged with the X-axis slide rail 421, and the two sets of Y-axis slide rails 422 are fixed to a first limit. Between the positioning block 411 and the second limiting block 412, a second slider is provided on the X-axis slide rail 421. The second slider is connected to the transmission component 434. A number of permanent magnets that cooperate with the magnetic components 413 of the first limiting block 411 and the second limiting block 412 are correspondingly provided on the connecting plate 423. The permanent magnets on the side of the connecting plate 423 closer to the first limiting block 411 have the same magnetic pole as the magnetic components 413 of the first limiting block 411, and the permanent magnets on the side of the connecting plate 423 closer to the second limiting block 412 have opposite magnetic poles to the magnetic components 413 of the second limiting block 412.

[0026] In this embodiment, the connecting plate 423 is provided with a plurality of positioning blocks 425, and the flip plate 3 is provided with locking members 426 that cooperate with the plurality of positioning blocks 425. The positioning blocks 425 are provided with arc-shaped limiting platforms, which are made of soft rubber and have good elasticity. The locking members 426 are provided with V-shaped grooves that are adapted to the arc-shaped limiting strips. The connecting plate 423 slides along the Y-axis slide rail 422 to drive the transmission member 434 to approach and engage with the output end of the test motor. After engagement, the positioning blocks 425 and the locking members 426 are in a cooperating state, limiting and fixing the connecting plate 423 to prevent displacement during the load test.

[0027] like Figure 5As shown, in this embodiment, the load assembly 43 includes two sets of fixing blocks 431, two sets of fixing rings 432, a rotating shaft 433, and a transmission component 434. The two sets of fixing blocks 431 are fixedly connected to the connecting plate 423. The two sets of fixing rings 432 are correspondingly sleeved on both ends of the rotating shaft 433, and both ends of the rotating shaft 433 are respectively fixedly connected to the two sets of fixing rings 432. The transmission component 434 is connected to the slide rail assembly 42 and slides in cooperation with the rotating shaft 433. The lower end of the transmission component 434 is engaged with the output end of the test motor. The rotating shaft 433 is provided with two sets of load elastic elements 435, and one end of each set of load elastic elements 435 is connected to... The fixed ring 432 is press-fitted, and the other ends of the two sets of load elastic elements 435 are push-fitted with the transmission element 434. The fixed block 431 is provided with a grommet screw, which is press-fitted with the fixed ring 432. Rotating the grommet screw adjusts the stroke of the fixed ring 432 on the reference axis to control the load provided by the load spring. The transmission element 434 is provided with an opening adapted to the rotating shaft 433. The lower end of the transmission element 434 is provided with a clearance slot, which is engaged with the output end of the test motor. When the output end of the test motor moves, it drives the transmission element 434 to reciprocate on the rotating shaft 433. The load elastic elements 435 located on both sides of the transmission element 434 continuously provide load force.

[0028] In this embodiment, the end of the transmission component 434 away from the test motor is provided with a gripping component 436. The two ends of the gripping component 436 are provided with grooves, the transmission rod is provided with an extension section, and the gripping component 436 is provided at one end of the extension section, so that the operator can pull the transmission component 434 to slide out or engage with the output end of the test motor on the Y-axis slide rail 422.

[0029] like Figure 2 As shown, in this embodiment, the flip plate 3 is also provided with a flip cover spring 5. One end of the flip cover spring 5 is pressed and engaged with the base 2, and the other end of the flip cover spring 5 is pushed and connected to the flip plate 3. The flip cover spring 5 is a torsion spring.

[0030] Working principle of the invention:

[0031] The test motor is guided into the fixed plate 1 along the positioning pin. The flip plate 3 falls around the base 2. The positioning pin presses the test motor. The buckle locks the flip plate 3 onto the fixed plate 1. The operator pulls the transmission component 434 to bring it close to the first limit block 411. Then, the transmission component 434 is moved and its lower end engages with the output end of the test motor. When the lower end of the transmission component 434 engages with the output end of the test motor, the positioning block 425 and the locking block are in a limit engagement state.

[0032] When the test motor receives the excitation signal, it starts to rotate. The output end of the test motor drives the transmission component 434 to reciprocate along the X-axis. During the reciprocating motion, the load elastic components 435 located on both sides of the transmission component 434 alternate between compression and release states, continuously applying load force.

[0033] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
