Description

Technical Field

[0001] The present invention relates to the technical field of data loaders, and more specifically, to a portable data loader and a usage method thereof. Background Art

[0002] A portable data loader is a device used for quickly and safely transmitting and loading data, and is usually used in fields such as aviation, military, and industrial automation. Its main function is to transfer data from one system to another system, for example, loading flight plans, software updates, or log data into aircraft, missiles, or other electronic devices.

[0003] In order to meet the usage requirements in different scenarios, portable data loaders are usually designed into two types: plug-in type and battery-swapping type. The plug-in device is powered by an external power supply and is suitable for use in fixed locations for a long time; while the battery-swapping device realizes mobile power supply through replaceable batteries and is applicable to outdoor or mobile environments. However, the battery-swapping portable data loader has significant defects in the waterproof performance of the battery swapping compartment. In the prior art, the waterproof design of the battery swapping compartment mainly relies on rubber sealing rings. However, the rubber sealing rings are prone to wear or deformation during the process of frequently replacing batteries, resulting in a decline in waterproof performance. As a result, the battery compartment of the portable data loader that mainly relies on rubber sealing rings for waterproofing is prone to water ingress, thereby damaging the internal electrical equipment. Therefore, it is necessary to propose a portable data loader and a usage method to solve the above problems. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a portable data loader and a usage method thereof, which can solve the problem of insufficient waterproof performance of some portable data loaders that mainly rely on sealing rings for waterproofing in the prior art.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] 1. By improving the battery compartment and the battery box into a matching cylindrical structure, the cylindrical design can significantly reduce the gap between the battery compartment and the battery box. Together with the adjustable screw-fixed cover and the sealing ring, the basic sealing performance is enhanced. When sliding the cover, its linkage mechanism not only triggers the mechanical locking function - driving the Z-shaped block to cooperate with the control groove through a long rod, driving the locking block to fix the positioning block to prevent the battery box from shaking, but also synchronously activates the airbag sealing mechanism: using the gear-rack transmission, the pressing rod is driven to push the piston to compress the inert gas, expanding the ring-shaped airbag to abut against the inner wall of the battery compartment, forming a waterproof barrier to isolate the entry of external water; moreover, a ring groove is provided inside the battery compartment, and the expanded airbag ring can be embedded in the ring groove to increase the contact area between the airbag ring and the battery compartment. The inert gas not only avoids the risk of oxidation and corrosion but also enables the airbag to have the characteristics of repeated charging and discharging. Combined with the nested design of the locking structure, the airbag ring, and the ring groove, the sealing contact area is expanded, further improving the sealing and waterproof performance between the battery compartment and the battery box.

[0018] 2. When the inert gas expands the airbag ring, it also drives the telescopic cylinder to slide through air pressure, thereby driving the sealing plate to insert into the positioning groove and abut against the arc-shaped inner wall of the positioning groove to initially seal the positioning groove. At the same time, aiming at the problem that the upper and lower sides of the sealing plate are easily worn when the sealing plate inserts into the positioning groove, expandable outer expansion plates and top plates are designed on the upper and lower sides of the sealing plate. When the sealing plate inserts into the positioning groove, the top plate contracts and does not contact the inner wall of the positioning groove, avoiding the reduction of sealing performance due to long-term friction. At the same time, using the air pressure introduced into the inflation cavity by the inert gas, the outer expansion plate and the top plate expand outwards, and the top plate closely adheres to the upper and lower straight-edge inner walls of the positioning groove, forming an actively pressed elastic sealing interface. To further strengthen the waterproof effect, sealing gaskets are provided on the end of the sealing plate and the surface of the top plate. Driven by gas pressure through the linkage of calipers, connecting plates, and springs, the arc-shaped side strips and straight-edge strips are urged to squeeze the sealing gaskets to form multiple folds. These folds not only extend the microscopic path of water penetration but also use material elasticity and surface tension to construct a dynamic barrier, achieving all-round and multi-level waterproof protection of the positioning groove and significantly improving the waterproof effect of the sealing plate on the positioning groove.

[0038] The power supply mechanism 3 further includes an electric core 32 installed inside the battery box 31. A positioning block 33 is installed on the side surface of the end of the battery box 31 extending into the battery compartment 15. The positioning block 33 is slidably connected inside the positioning slot 16. A first spring 36 is installed in the pumping cavity 34, and the piston column 35 is elastically connected to the inside of the pumping cavity 34 through the first spring 36.

[0039] Inside the main body 11, a control mechanism 7 is installed. The control mechanism 7 includes a long rod 71 slidably connected inside the main body 11. The front end of the long rod 71 is located inside the sliding groove 13. A fifth spring 72 is sleeved on the long rod 71. A first rack 73 is installed on the side of the long rod 71. A Z-shaped block 74 is installed at the tail end of the long rod 71. A lock block 75 is slidably connected inside the main body 11. A regulation groove 76 is provided through the lock block 75, and the Z-shaped block 74 is slidably connected inside the regulation groove 76.

[0040] Inside the main body 11, a pressing mechanism 8 is installed. The pressing mechanism 8 includes a pressing rod 81 slidably connected inside the main body 11, and the long rod 71 passes through the pressing rod 81. A second rack 82 is installed at the top of the pressing rod 81. A small gear 83 and a large gear 84 are installed inside the main body 11. The small gear 83 is installed at the bottom of the large gear 84, and the small gear 83 is meshed and connected with the first rack 73, and the large gear 84 is meshed and connected with the second rack 82.

[0041] Most of the detachable batteries of traditional portable data loaders are designed in a rectangular shape. Because rectangular batteries have high space utilization and larger capacity, the rectangular design may cause many right angles in the battery compartment for installing the battery, which are prone to leaving gaps. Coupled with the aging of the sealing ring for sealing and waterproofing at the battery compartment opening, the sealing performance is reduced, and the probability of water entering the battery compartment is greatly increased.

[0042] In order to further improve the waterproof performance of the portable data loader, on the premise of originally installing the sealing ring 17, the battery compartment 15 is designed to be cylindrical, and the battery box 31 and the battery cell 32 are designed into corresponding cylindrical structures. The battery cell 32 is installed inside the battery box 31, and the battery box 31 is installed inside the battery compartment 15, making the battery compartment 15 and the battery box 31 fit more closely, which can effectively reduce the gap between the battery compartment 15 and the battery box 31, and to a certain extent reduce the possibility of moisture penetrating into the interior of the battery compartment 15.

[0043] When installing the battery box 31, first turn the screw 23 on the screw seat 22 to release the screw 23 from the screw hole 14, and then slide the cover 21 to the right (in accordance with the attached Figure 1In the shown orientation, the cover 21 slides inside the opening slot 12 and drives the secondary plate slider 25 on the secondary plate 24 to slide in the sliding slot 13 until the cover 21 slides to the rightmost end of the opening slot 12, exposing the battery compartment 15. Then, the battery box 31 with the battery cell 32 installed inside is inserted into the battery compartment 15. Finally, the electrodes at the bottom of the battery cell 32 are in contact with the energized contacts inside the main unit 11, thus turning on the power supply. Slide the cover 21 in the reverse direction along the original path to re-cover the battery compartment 15 with the cover 21, that is, the screw 23 on the screw seat 22 aligns with the screw hole 14 inside the opening slot 12 again. Rotate the screw 23, and the screw 23 is threadedly connected to the screw hole 14 again and presses the screw seat 22 tightly, making the cover 21 tightly contact the surface of the main unit 11. A sealing ring 17 is arranged around the battery compartment 15. By installing the cover 21 in the way of threaded connection between the screw 23 and the screw hole 14, the tightness of the cover 21 against the sealing ring 17 can be freely adjusted as needed, thus facilitating the control of the sealing performance of the cover 21 for the battery compartment 15.

[0044] There is a drawback in that the battery compartment 15 and the battery box 31 are designed as a cylindrical structure, that is, it is impossible to accurately grasp the angle of each insertion of the battery box 31 into the battery compartment 15, so it is impossible to ensure that the electrodes of the battery cell 32 accurately contact the corresponding energized contacts. Therefore, a positioning slot 16 with the same depth as the battery compartment 15 is provided inside the main unit 11 beside the battery compartment 15, and a positioning block 33 is arranged on the bottom side of the battery box 31. Each time the battery box 31 is inserted into the battery compartment 15, first align the positioning block 33 with the positioning slot 16. When the battery box 31 slides in the battery compartment 15, the positioning block 33 slides in the positioning slot 16. In this way, it can be ensured that each time the battery box 31 is installed, the angle of the battery box 31 is accurate, and the electrodes at the bottom of the battery cell 32 can accurately contact the corresponding energized contacts. After the battery box 31 is installed, the positioning block 33 reaches the deepest part of the positioning slot 16. During the process of the cover 21 sliding to the left side of the opening slot 12, it still drives the slider 25 to slide inside the sliding slot 13 through the secondary plate 24. When the cover 21 is about to slide to the end point, the slider 25 contacts the ejected long rod 71 and pushes the long rod 71 into the main unit 11. The long rod 71 compresses the fifth spring 72. During the process of the long rod 71 sliding into the main unit 11, it drives the Z-shaped block 74 at its end to move synchronously, so that the upward pushing head of the Z-shaped block 74 squeezes the upper inclined surface of the regulation slot 76 (as shown in the attached drawings of the specification Figure 5 As shown, let the upper end of the Z-shaped block 74 be the upward pushing head and the lower end be the downward pushing head, and the inclined surfaces at the corresponding positions of the regulation slot 76 are the upper inclined surface and the lower inclined surface), as shown in the attached drawings of the specification Figure 3 As shown, the above process drives the lock block 75 to slide into the positioning slot 16, thus contacting the positioning block 33 and preventing the positioning block 33 from sliding freely, and then locking the battery box 31, avoiding the problem that the battery box 31 accidentally shakes during the use of the main unit 11, resulting in unstable connection between the electrodes on the battery cell 32 and the energized contacts, and at the same time providing a guarantee for improving the sealing performance and waterproof performance in the follow-up.

[0045] Although the battery case 31 fits more closely to the battery compartment 15, it is still difficult to well avoid water from penetrating into the battery compartment 15, causing problems such as short circuit. Therefore, during the process of the slider 25 pushing the long rod 71, the fifth spring 72 drives the first rack 73 to move, the first rack 73 drives the pinion 83 to rotate, the pinion 83 drives the large gear 84 to rotate, increasing the torque, so that the moving distance of the second rack 82 meshed with the large gear 84 increases. The second rack 82 drives the pressing rod 81 to horizontally pass through the positioning groove 16 and insert into the inside of the side of the battery case 31 (a notch is provided in the middle of the pressing rod 81 to avoid interfering with the long rod 71 during its own sliding process), squeezing and pushing the piston column 35 to slide inside the air pumping cavity 34, compressing the first spring 36 inside the air pumping cavity 34. There is inert gas inside the air pumping cavity 34. When the piston column 35 slides inside the air pumping cavity 34, the inert gas is pushed into the connecting pipe 41, and then evenly filled into the airbag ring 44 through the distribution cavity 42 and the distribution pipe 43, causing the annular airbag ring 44 on the outer surface of the battery case 31 to bulge, intercepting between the battery compartment 15 and the battery case 31. Once the battery compartment 15 gets water, the inflated airbag ring 44 forms a barrier, blocking between the battery compartment 15 and the battery case 31, reducing the amount of water penetrating deep into the battery compartment 15, and improving the sealing performance and waterproof effect. After the lock block 75 locks the positioning block 33, the position of the airbag ring 44 is exactly aligned with the annular groove 18 provided inside the battery compartment 15. When the airbag ring 44 expands, the airbag ring 44 exactly fills into the annular groove 18. In this way, the surface area of mutual contact between the airbag ring 44 and the inside of the battery compartment 15 increases, further improving the sealing effect.

[0046] Embodiment 2 is an explanatory description made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 11 , a second sealing mechanism 5 is installed inside the battery case 31. The second sealing mechanism 5 includes a telescopic cylinder 51 and a second spring 52 installed inside the battery case 31. The telescopic cylinder 51 is elastically connected to the battery case 31 through the second spring 52, and the telescopic cylinder 51 is slidably connected inside the connecting pipe 41. A sealing plate 53 is installed at the end of the telescopic cylinder 51, and the sealing plate 53 is slidably connected inside the battery case 31. An air inflation cavity 54 is provided inside the sealing plate 53, and the air inflation cavity 54 is communicated with the telescopic cylinder 51. Outer expansion plates 55 are slidably connected inside both sides of the sealing plate 53, and the inner ends of the outer expansion plates 55 are slidably connected inside the air inflation cavity 54. A top plate 56 is installed at the outer ends of the outer expansion plates 55.

[0047] An enhancement mechanism 6 is provided on the sealing plate 53. The enhancement mechanism 6 includes a sealing gasket 61 provided on the cylindrical surface of the sealing plate 53 and the surface of the top plate 56. Two arc-shaped side strips 62 are symmetrically arranged on both sides of the cylindrical surface of the sealing plate 53, and both sides corresponding to the sealing gasket 61 are respectively installed inside the two arc-shaped side strips 62. Two connecting plates 63 are symmetrically installed inside both the sealing plate 53 and the outward expansion plate 55, and one ends of the two connecting plates 63 are respectively symmetrically installed on the two arc-shaped side strips 62. A third spring 64 is installed between the two connecting plates 63. A caliper 65 is installed inside the sealing plate 53. The caliper 65 abuts against the other ends of the two connecting plates 63. An air push rod 66 is installed on the caliper 65. The end of the air push rod 66 is slidably connected inside the inflation cavity 54. A fourth spring 67 is sleeved on the air push rod 66. Two straight side strips 68 are symmetrically installed on the surface of the top plate 56. Both sides of the sealing gasket 61 on the surface of the top plate 56 are respectively installed inside the two straight side strips 68, and one ends of the two connecting plates 63 inside the outward expansion plate 55 are respectively installed on the surfaces of the corresponding straight side strips 68. Protrusions 69 are installed at the other ends of the connecting plates 63 inside the outward expansion plate 55. The third spring 64 is installed inside the protrusions 69.

[0048] When the airbag ring 44 expands to improve the sealing and waterproof performance between the battery box 31 and the battery compartment 15, the positioning groove 16 communicated with the battery compartment 15 also needs to be waterproofed. When the inert gas in the air pumping cavity 34 is pressed into the communicating pipe 41, the air pressure pushes the telescopic cylinder 51 inside the communicating pipe 41 to slide outwards from the battery box 31 (a disc for increasing resistance is provided at the end of the telescopic cylinder 51 to increase the pressure so that the air flow drives the telescopic cylinder 51 to slide inside the communicating pipe 41, but the diameter of the disc is smaller than the inner diameter of the communicating pipe 41 to prevent the disc from completely blocking the flow of inert gas). The telescopic cylinder 51 drives the sealing plate 53 to slide out from the inside of the battery box 31 and insert into the positioning groove 16. The shape of the end of the sealing plate 53 fits the arc-shaped inner wall of the positioning groove 16, and the end of the sealing plate 53 can well fit the inner wall of the positioning groove 16, thus blocking the arc-shaped end of the positioning groove 16 and preventing external water from entering from the arc-shaped side of the positioning groove 16.

[0049] Since the sealing plate 53 is horizontally inserted into the positioning groove 16, the upper and lower sides of the sealing plate 53 rub against the upper and lower sides of the positioning groove 16 for a long time, which will inevitably reduce the sealing performance of the sealing plate 53 to the positioning groove 16. Therefore, expandable outer expansion plates 55 and top plates 56 are designed on the upper and lower sides of the sealing plate 53. When the outer expansion plate 55 drives the top plate 56 to contract, when the sealing plate 53 is inserted into the positioning groove 16, the top plate 56 does not contact the upper and lower inner walls of the positioning groove 16, thus avoiding friction and reducing wear of the top plate 56. The telescopic cylinder 51 is also designed as a hollow structure, which is communicated with the inflatable cavity 54 inside the sealing plate 53. A part of the inert gas passing through the communication pipe 41 passes through the telescopic cylinder 51, enters the inflatable cavity 54, and pushes the outer expansion plates 55 on both sides of the sealing plate 53, so that the outer expansion plates 55 drive the top plates 56 to more tightly abut against the upper and lower inner walls of the positioning groove 16 (the upper and lower inner walls are straight edges), thereby ensuring the waterproof performance of the upper and lower sides of the positioning groove 16.

[0050] During the whole process after the battery box 31 is installed inside the battery compartment 15, the piston rod 35 is always squeezed by the pressing rod 81, that is, the piston rod 35 in the air pumping cavity 34 always applies pressure to the inert gas, ensuring that the inert gas expands the airbag ring 44, presses the telescopic cylinder 51, and fills the inflatable cavity 54, so that the outer expansion plates 55 drive the top plates 56 to abut against the upper and lower inner walls of the positioning groove 16.

[0051] Relying solely on the piston rod 35 to apply pressure to the inert gas to make the surfaces of the sealing plate 53 and the top plate 56 abut against the inner wall of the positioning groove 16, so as to achieve the waterproof effect of the positioning groove 16 is still lacking. Therefore, sealing gaskets 61 are provided on the end of the sealing plate 53 and the surface of the top plate 56. The sealing gaskets 61 are made of silicone or Teflon materials and have good anti-aging and elasticity. When the inert gas enters the inflatable cavity 54 and pushes the outer expansion plates 55, it also pushes the air push rods 66. The air push rods 66 compress the fourth springs 67 and drive the calipers 65 to squeeze the two connecting plates 63, so that the two connecting plates 63 approach each other. The connecting plates 63 drive the corresponding arc-shaped side strips 62 to move and compress the third springs 64. The two arc-shaped side strips 62 relatively squeeze the sealing gasket 61, causing the sealing gasket 61 to wrinkle; similarly, during the process of the outer expansion plate 55 sliding outward from the sealing plate 53, the inner wall of the sealing plate 53 squeezes the convex blocks 69 protruding from both sides of the outer expansion plate 55, so that the convex blocks 69 drive the corresponding connecting plates 63 to slide inward into the outer expansion plate 55, compress the corresponding third springs 64, and the connecting plates 63 drive the corresponding straight-edge strips 68 to approach each other, squeezing the sealing gasket 61 on the inner side of the straight-edge strips 68, also causing wrinkles. The wrinkles of the sealing gasket 61 form a complex path, increasing the resistance to water penetration and delaying or preventing the passage of water; moreover, the microscopic structure of the wrinkles may utilize the surface tension of water to prevent water from passing through the contact surface between the sealing gasket 61 and the positioning groove 16, further improving the waterproof performance of the sealing plate 53 to the positioning groove 16.
