Description

Technical Field

[0001] This invention relates to the field of aging test technology, specifically to a loading bin for an OBC-loaded feedback water-cooled aging platform. Background Technology

[0002] In the field of electronic product aging technology, OBC load-fed feedback water-cooled aging platforms are commonly used to conduct aging tests on electronic products. However, existing OBC load-fed feedback water-cooled aging platforms typically only have one or more loading chambers of fixed size, making it difficult to adapt to aging tests of electronic products of different specifications. Utility model with announcement number CN210982505U discloses a loading chamber for an OBC load-fed feedback water-cooled aging platform, including an aging chamber, an electrical control cabinet, and a water circulation cabinet. This allows the size of the loading chamber to be adjusted according to actual needs, greatly improving the practicality of the aging chamber.

[0003] Although this device has the advantages mentioned above, it still has the following drawbacks in practical use: 1) When the interior of the aging chamber is divided using partitions and loading plates, the small spaces at the partitions will exist independently, which can easily affect the internal airflow and temperature transfer, resulting in poor actual aging test results and efficiency. 2) The loading plate is fixed by the insertion of the limiting cylinder and the limiting hole. However, the axial sliding insertion can easily lead to insufficient stability of the loading plate. In particular, when the electronic product is removed, the friction between the two can easily cause the limiting cylinder to dislodge, resulting in the loading plate and the electronic product falling and being damaged.

[0004] Therefore, improvements are needed to address the problems that still exist in the use of existing devices. Summary of the Invention

[0014] Beneficial effects This invention provides a loading bin for an OBC (On-Board Charge) water-cooled aging platform. Compared with the prior art, it has the following advantages: (1) By setting up a separation mechanism, the connecting plate and the slider can slide in the adjustment groove, the circular groove and the sliding groove, so that the rotating rod can adjust the size of the separation space longitudinally. At the same time, by using multiple rotating rods as a group, it is possible to facilitate the loading and unloading of electronic products by rotating them, and the gap between the rotating rods can facilitate the flow of air and the transfer of temperature inside the test chamber, thereby improving the effect and efficiency of aging test.

[0015] (2) By setting up a synchronization component, the transmission connection of the chain and sprocket can enable each set of rotating rods to rotate in the same direction and at the same speed, so as to facilitate the feeding and unloading of electronic products. At the same time, by using the sliding sleeve of the gear and the gear, the radial limit of one of the rotating rods can be achieved. Then, by the combination of the chain and sprocket, all the rotating rods can be kept stable, thereby maintaining the stability of the electronic products inside the test box. At the same time, by using the difference in outer diameter of the rotating roller and the rotating rod, the working space of the gear sleeve and sprocket can be provided, avoiding contact with the electronic products and affecting the feeding and unloading problem.

[0016] (3) By setting a limit unit, the output end of the piston rod extends and drives the abutment block to move when the internal air pressure of the piston rod increases during the test. The abutment block then improves the stability of the connection between the abutment block and the gear sleeve through the contact action of the inclined surface and the gear sleeve, thereby further improving the stability of the roller and electronic products.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-5 This invention provides a technical solution: a loading bin for an OBC-loaded feedback water-cooled aging platform. The test chamber 1 is constructed using an existing aging chamber structure. Inside the test chamber 1, a partitioning mechanism is provided, including rotating rods 2. The outer surface of the rotating rods 2 is movably connected to the interior of the test chamber 1. At least three rotating rods 2 are arranged at equal intervals on a horizontal plane, grouped together. The number of rotating rods 2 is determined based on the internal space of the test chamber 1 and the specifications of the electronic products. Sliding sliders 4 are embedded and rotatably connected at both ends of the rotating rods 2. Fixed plates 5 are provided on the outer sides of both ends of the rotating rods 2. A groove 6 is formed on one side of the outer surface of the fixed plates 5. The width and depth of the groove 6 are the same as the length and width of the sliding slider 4, but the inner length of the groove 6 is greater than the thickness of the sliding slider 4. The outer surface of the sliding slider 4 is slidably connected to the interior of the groove 6. An adjustment groove 7 is formed on the other side of the outer surface of the fixed plate 5. The inner width of the adjustment groove 7 is smaller than the inner width of the groove 6. The interior of the adjustment groove 7 is connected to the interior of the groove 6. A through rotating groove 8 is formed in the body of the sliding slider 4. The groove 8 has a slot 9 inside, the diameter of which is greater than that of the rotating groove 8, but the shaft of the rotating groove 8 is greater than that of the slot 9, so as to play an axial limiting role. The slot 9 is rotatably connected to a circular plate 10. The circular plate 10 can rotate through its outer arc surface and can achieve axial limiting through its cooperation with the slot 9. The body of the circular plate 10 is fixedly connected to a connecting plate 11. The connecting plate 11 is fixedly connected to multiple circular plates 10 to connect the sliders 4 on one side of each set of rotating rods 2. The outer surface of the connecting plate 11 is rotatably connected to the interior of the rotating groove 8, the sliding groove 6 and the adjusting groove 7 respectively. The adjusting groove 7 has a circular groove 12 inside, the inner diameter of which is the same as that of the rotating groove 8, and multiple circular grooves are arranged at equal intervals along the longitudinal direction. The outer surface of the connecting plate 11 is rotatably connected to the interior of the circular groove 12. The two ends of the connecting plate 11 are provided with arc edges. The arc edges of the connecting plate 11 limit the sliders 4 longitudinally by abutting against the interior of the circular groove 12.

[0021] Both sides of the inner side of the circular groove 12 are movably connected to the arc plates 13. The two arc plates 13 and one end of the connecting plate 11 can be assembled into a cylindrical shape, and the outer arc surface is provided with external threads. The outer surfaces of the two arc plates 13 are movably connected to the outer surfaces of the connecting plate 11. The outer surfaces of the two arc plates 13 are fixedly connected to the clamping plates 14. The width of the clamping plates 14 is the same as the inner width of the adjustment groove 7, so as to axially limit the connecting plate 11 through the arc plates 13. The outer surfaces of the two clamping plates 14 are radially engaged with the inner side of the adjustment groove 7.

[0022] The connecting plate 11 is threadedly connected to the arc edge with a threaded sleeve 15. The threaded sleeve 15 has an internal thread, and the inside of the threaded sleeve 15 is threadedly connected to the outer surface of the two arc plates 13 respectively.

[0023] A synchronization component 3 is provided on the outside of the rotating rod 2. The synchronization component 3 includes a rotating roller 31. The outer diameter of the rotating roller 31 is larger than the outer diameter of the rotating rod 2. The working space can be provided by the difference in outer diameter. The body of the rotating roller 31 is fixedly connected to the outer surface of the rotating rod 2. The outer surface of the rotating roller 31 is rotatably connected to the inside of the test box 1. A sprocket 32 ​​is provided on one side of the outer surface of the rotating roller 31. The sprocket 32 ​​is fixed on one side of the outer surface of each group of rotating rods 2. The outer surfaces of the sprockets 32 are connected by a chain 33. The cooperation of the sprockets 32 can keep the rotating rods 2 of each group synchronized.

[0024] A gear 34 is provided on the other side of the outer surface of the roller 31. The outer surface of the gear 34 is fixedly connected to the outer surface of the slider 4. The body of the gear 34 is rotatably connected to the other side of the outer surface of one of the rotating rods 2. A toothed sleeve 35 is slidably connected to the outer surface of the gear 34. The toothed sleeve 35 has internal teeth. By meshing with the teeth of the gear 34, the radial limit of the rotating rod 2 and the roller 31 is achieved. The toothed sleeve 35 is slidably sleeved on the outer surface of one of the rotating rods 2. A spring rod 37 is fixedly connected to the outer surface of the toothed sleeve 35. The spring rod 37 can easily control the connection between the toothed sleeve 35 and the gear 34 by elastic extension and retraction. The outer surface of the spring rod 37 is embedded and fixedly connected to the outer surface of the roller 31.

[0025] The toothed sleeve 35 is provided with a limiting unit 36 ​​on its outside. The limiting unit 36 ​​includes a stop block 361. The outer surface of the stop block 361 is slidably connected to the inside of the test box 1. The bottom of the stop block 361 is provided with an inclined surface 362. The inclined surface 362 faces the toothed sleeve 35 and the slider 4. The toothed sleeve 35 is kept in contact with the gear 34 by the inclined abutment action. The outer surface of the inclined surface 362 is movably connected to the outer surface of the toothed sleeve 35. The outer surface of the inclined surface 362 is provided with a clamping groove 363. The inner width of the clamping groove 363 is the same as the diameter of the rotating rod 2. The upper part of the inner wall is provided with an arc surface to improve the force bearing capacity and stability of the stop block 361 by increasing the contact range with the surface of the rotating rod 2. The inside of the clamping groove 363 is movably connected to the outer surface of the rotating rod 2.

[0026] A piston rod 364 is fixedly connected to the outer surface of the abutment block 361. An active gas is installed inside the piston rod 364. During the aging test, the active gas is heated and collided to increase the gas pressure inside the piston rod 364, causing its output end to slide outward to drive the abutment block 361 to move and abut against the toothed sleeve 35. A support plate 365 is fixedly connected to one end of the piston rod 364. The outer surface of the support plate 365 is fixedly connected to the outer surface of the slider 4.

[0027] A tension spring 366 is sleeved on the outside of the piston rod 364. The tension spring 366 can maintain the compression state of the output end of the piston rod 364 when it is stationary by its own elastic force. The two ends of the tension spring 366 are fixedly connected to the outer surface of the stop block 361 and the support plate 365, respectively.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: When aging tests are required on electronic products, first, according to the appearance and size of the electronic product, hold one end of the connecting plate 11 and let it slide up and down inside the adjustment groove 7. Then, through the action of the circular plate 10, the slider 4 moves synchronously inside the slide groove 6 to adjust the height of the rotating rod 2 and the rotating roller 31 inside the test chamber 1. When the connecting plate 11 is slid to the circular groove 12 at the corresponding height, rotate the connecting plate 11 by 90° so that its two arc edges rotate into the circular groove 12. The slider 4 and the rotating rod 2 are supported by the contact with the inner wall of the circular groove 12. Then, place two arc plates 13 symmetrically inside the circular groove 12. The radial limit of the connecting plate 11 is completed by the contact of the arc plates 13 and the connecting plate 11, and the contact of the clamping plate 14 and the adjustment groove 7. Then, screw the screw sleeve 15 on one end of the arc plates 13 and the connecting plate 11 so that the two limit each other, thereby completing the height fixation of the rotating rod 2. Next, the electronic product to be tested is placed inside the test chamber 1 and supported by the rotating roller 31 on the surface of the rotating rod 2. Then, the reverse sliding sleeve 35 is used to disengage it from the gear 34, while compressing the output end of the spring rod 37. The electronic product is then pushed inward, and the rotation of the rotating rod 2 and the rotating roller 31 allows the electronic product to slide completely into the test chamber 1. Subsequently, the sleeve 35 is released and reset by the spring return of the output end of the spring rod 37, so that the sleeve 35 slides onto the outside of the gear 34. Through the meshing of the teeth, the rotation of the outermost rotating rod 2 is restricted. Then, through the transmission connection of the sprocket 32 ​​and the chain 33, all the rotating rods 2 in the same group are radially limited, thereby improving the stability of the electronic product. During the test, as the internal temperature of the test chamber 1 rises, the active gas inside the piston rod 364 heats up and expands, causing the internal air pressure of the piston rod 364 to rise. This causes the output end of the piston rod 364 to slide out, thereby causing the stop block 361 to descend and approach the toothed sleeve 35. The stop block 361 then abuts against one side of the toothed sleeve 35 through the inclined surface 362 and one side surface, keeping the toothed sleeve 35 fitted outside the gear 34. This further improves the stability of the rotating roller 31 and the electronic product. Furthermore, when the stop block 361 descends, the clamping action of the clamping groove 363 and the rotating rod 2 enhances the stability and force resistance of the abutment against the toothed sleeve 35.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
