Description

Technical Field

[0001] This invention belongs to the field of power supply technology, specifically an integrated intelligent DC power supply based on supercapacitors. Background Technology

[0002] Supercapacitor modules are the core energy storage units of integrated intelligent DC power supplies and are key to ensuring the overall performance, charging efficiency and safety of the power supply. Currently, the mainstream connection method between supercapacitor modules (especially modules composed of multiple individual units) and circuit boards still relies on soldering processes.

[0003] However, in some scenarios, such as when the power supply is used for extended periods in complex conditions like in vehicles, mobile devices, and industrial environments, it is subjected to long-term vibration stress. This can easily lead to fatigue cracks in the solder joints, resulting in increased connection resistance, localized overheating, and even complete detachment, causing electrical connection failure. To address the connection reliability issues caused by vibration, existing technologies have proposed several improvement solutions. For example, the solution disclosed in patent document CN207425639U improves the vibration-resistant structure of the supercapacitor cell itself by setting an interlocking connection between the cell and the current collector, utilizing the elastic deformation of the metal current collector to buffer vibration and prevent solder joint detachment. Reference CN213583526U focuses on the mechanical fixation of the entire module, such as using a detachable interconnect positioning cover to clamp the suspended end of the capacitor. However, these solutions have obvious limitations: the former mainly strengthens the internal structure of the capacitor but does not solve the problem of shock resistance and maintainability of the interface connection between the entire module as a whole unit and the external power system; the latter focuses more on physical fixation and does not involve active pressure maintenance and rapid switching functions of electrical connection points, and its reliability will decrease after repeated disassembly and assembly. Therefore, this application provides an integrated intelligent DC power supply based on supercapacitors to solve the above problems. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an integrated intelligent DC power supply based on a supercapacitor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated intelligent DC power supply based on a supercapacitor, comprising a main body, a supercapacitor module, and a charge / discharge management circuit. The main body includes an electrically connected circuit board and a mounting base. The charge / discharge management circuit is disposed on the circuit board and includes at least a DC input interface, a control unit, and a DC output interface for controlling the charging and discharging process of the supercapacitor module. It also includes a module connection mechanism, which includes a mounting base, a manual pressing mechanism disposed on the mounting base, and a module locking seat. The pressure plate of the receiving mechanism is made of conductive material and is electrically connected to the DC output interface of the charge / discharge management circuit; the module locking seat is used to accommodate the supercapacitor module, and the manual pressing mechanism is used to detachably press and fix the supercapacitor module, and make the electrodes of the supercapacitor module electrically connected to the pressure plate, thereby connecting the supercapacitor module to the charge / discharge circuit formed by the charge / discharge management circuit; the main body also includes a cover plate, the cover plate is provided with an upper fastening mechanism, and the upper fastening mechanism includes a pressure plate fixed to the bottom arm of the cover plate, and the module locking seat is fixed to the mounting base.

[0006] In the above technical solution, preferably, the lower positioning mechanism includes a second inner groove and a first inner groove formed within the module locking seat. A slide rod is slidably connected between the second inner groove and the first inner groove. A placement plate is fixedly connected to the top of the slide rod, and a limit plate is fixedly connected to the bottom of the slide rod. A compression spring located in the first inner groove is provided at the bottom of the limit plate. A hollow block is fixedly connected within the second inner groove. Several movable grooves are formed on the peripheral sidewall of the hollow block. Each of the several movable grooves is fixedly connected to a mounting rod, and each of the several mounting rods is slidably connected to a gear. Each gear has a fixed positioning clamping arm at its outer end, and several racks are fixedly connected to the side wall of the slide bar, with the racks meshing with several gears. The positioning clamping arms are multiple and arranged in a ring, and have an L-shaped structure. By using the gears and racks, the supercapacitor module is first placed on the placement plate between the multiple positioning clamping arms in the module locking seat for pre-positioning. When the cover plate is installed, the pressure plate on the bottom wall of the cover plate presses onto the supercapacitor module, causing the supercapacitor module to gradually move downwards. Simultaneously, the placement plate... As the sliding rod moves downward, the meshing of the rack and gear on the sidewall of the sliding rod causes the positioning clamping arm to rotate inward. The top of the positioning clamping arm gradually increases the pressure on the supercapacitor module. Simultaneously, multiple positioning clamping arms press synchronously, automatically positioning the offset supercapacitor module to the center position for automatic adjustment and fixation. When maintenance is required, the cover plate is first opened and the module is removed. At this time, the supercapacitor module is released from the pressure plate, and the compression spring that was compressed resets, causing the sliding rod to reset. The meshing of the rack and gear on the sidewall of the sliding rod causes multiple positioning clamping arms to unfold outward. By ejecting the supercapacitor module and unfolding multiple positioning clamping arms, it is convenient for staff to remove the supercapacitor module for maintenance and replacement. Several extension plates are fixedly connected to the sidewall of the placement plate. These extension plates are located between several positioning clamping arms. By setting extension plates on the sidewall of the placement plate, the area of ​​the placement plate is increased without affecting the positioning clamping arms, thus accommodating supercapacitor modules of different sizes.

[0007] In the above technical solution, preferably, an inner conductive rod is fixed at the center of the slide bar, and a first elastic contact piece that can move within the mounting base is fixed at the bottom end of the inner conductive rod. The placement plate is provided with a slot and a guide groove. A second elastic contact piece is fixedly connected in the slot. After the supercapacitor module is installed, the conductive rod at the bottom end of the supercapacitor module is inserted into the slot and pressed into contact with the second elastic contact piece to achieve electrical connection.

[0008] In the above technical solution, preferably, a first protective pad is fixedly connected to the placement plate, and a second protective pad is fixedly connected to the end of the positioning clamping arm away from the gear. By setting the first and second protective pads, the protective pads are made of rubber. On the one hand, the protective pads can protect the supercapacitor module when they come into contact with the supercapacitor module, avoiding wear on the supercapacitor module. On the other hand, they can improve friction, thereby preventing the supercapacitor module from shifting when the pressure ring is tightened.

[0009] In the above technical solution, preferably, a third lead screw is fixedly connected to the mounting base, and the third lead screw is threadedly connected to the first inner groove. Several fixed rods arranged at equal intervals are fixedly connected to the mounting base. A rotating seat is rotatably connected to the outer end of the module locking seat. Fixed feet that slide and engage with several fixed rods are fixedly connected to the peripheral side wall of the rotating seat. By setting the third lead screw, the module locking seat and the third lead screw can be threadedly engaged by rotating the module locking seat. At the same time, the rotating seat at the outer end of the module locking seat slides and engages with the fixed rods. Therefore, when the module locking seat is rotated, the compressibility of the compression spring can be adjusted, which is conducive to adjusting the required pressure according to the processing needs.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. This invention integrates a mechanical module connection mechanism with a high-performance charge and discharge management circuit into a single solution. The connection mechanism provides a stable, low-impedance electrical interface with vibration resistance for the charge and discharge circuit, solving the problem that traditional welding or bolt connections are prone to loosening, leading to increased contact resistance or even failure in vibration and shock environments such as vehicles and industries.

[0012] 2. By setting up a lower fastening mechanism, the present invention allows operators to simultaneously complete the entire process of electrical connection, locking and unlocking, and ejection of the supercapacitor module by manually pressing down and lifting up, thereby simplifying operation, reducing maintenance threshold and time costs, and improving power supply availability.

[0013] 3. By setting a first protective pad and a second protective pad, the present invention can protect the supercapacitor module when the protective pad contacts the supercapacitor module, avoiding wear on the supercapacitor module. On the other hand, it can improve friction, thereby preventing the supercapacitor module from shifting when the pressure ring is tightened. By setting a module locking seat and a third lead screw thread engagement, the compressibility of the compression spring can be adjusted when the module locking seat is rotated, which is conducive to adjusting the required pressure according to processing needs.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0029] like Figures 1 to 12 As shown, this invention provides an integrated intelligent DC power supply based on supercapacitors, including a main body 1, a supercapacitor module 9, and a charge / discharge management circuit. The main body 1 includes an electrically connected circuit board 3 and a mounting base 2. The charge / discharge management circuit is disposed on the circuit board 3 and includes at least a DC input interface, a control unit, and a DC output interface for controlling the charging and discharging process of the supercapacitor module 9. It also includes a module connection mechanism, which includes the mounting base 2, a manual pressing mechanism disposed on the mounting base 2, and a module locking seat 16. The pressure plate 11 of the manual pressing mechanism is made of conductive material and is electrically connected to the DC output interface of the charge / discharge management circuit. The module locking seat 16 is used to accommodate the supercapacitor module 9. The manual pressing mechanism is used to detachably press and fix the supercapacitor module 9 and make the electrodes of the supercapacitor module 9 electrically connected to the pressure plate 11, thereby connecting the supercapacitor module 9 into the charge / discharge circuit formed by the charge / discharge management circuit. The body 1 also includes a cover plate 4, on which an upper fastening mechanism is provided. The upper fastening mechanism includes a pressure plate 11 fixed to the bottom arm of the cover plate 4, and the module locking seat 16 is fixed to the mounting base 2. The charge and discharge management circuit is integrated on the circuit board 3, and its core may include, but is not limited to, a bidirectional DC-DC converter, a voltage and current sampling module, a microprocessor control unit, and necessary protection circuits (not shown separately in the figure). The DC output terminal of the charge and discharge management circuit is connected to the manual crimping machine through printed circuit board traces or flexible conductive busbars. The pressure plate 11 of the structure enables electrical connection. During use, an external power source (such as an AC adapter or generator) or load is connected to the charging and discharging management circuit through the corresponding interface on the main body 1. When charging is required, the charging and discharging management circuit controls the external electrical energy to flow to the clamped supercapacitor module 9 through the pressure plate 11 after being converted by the circuit. When discharging is required, the electrical energy stored in the supercapacitor module 9 is output to the load through the pressure plate 11 and the circuit. The module connection mechanism can not only be physically fixed, but also serve as a circuit node that can be quickly plugged in and unplugged in the charging and discharging circuit.

[0030] The lower positioning mechanism includes a second inner groove 21 and a first inner groove 20 formed within the module locking seat 16. A slide rod 25 is slidably connected between the second inner groove 21 and the first inner groove 20. A placement plate 32 is fixedly connected to the top of the slide rod 25, and a limit plate 23 is fixedly connected to the bottom of the slide rod 25. A compression spring 24 located in the first inner groove 20 is provided at the bottom of the limit plate 23. A hollow block 26 is fixedly connected within the second inner groove 21. Several movable grooves 27 are formed on the periphery of the hollow block 26. Mounting rods 28 are fixedly connected to each of the movable grooves 27, and gears 29 are slidably connected to each of the mounting rods 28. Positioning clamping arms 30 are fixedly connected to the outer ends of each of the gears 29. Several racks 31 are fixedly connected to the periphery of the slide rod 25, and the racks 31 mesh with the gears 29. The positioning clamping arms 30 are multiple and arranged in a ring, and each positioning clamping arm 30 has an L-shaped structure. With gear 29 and rack 31, in use, the supercapacitor module 9 is first placed on the placement plate 32 between multiple positioning clamping arms 30 in the module locking seat 16 for pre-positioning. When the cover plate 4 is installed, the pressure plate 11 on the bottom wall of the cover plate 4 presses on the supercapacitor module 9, causing the supercapacitor module 9 to gradually move down. At the same time, the placement plate 32 drives the slide rod to move down. Since the rack 31 and gear 29 on the side wall of the slide rod 25 mesh, the positioning clamping arm 30 rotates inward when the slide rod 25 moves down. The top of the positioning clamping arm gradually increases the pressure on the supercapacitor module. At the same time, multiple positioning clamping arms 30 press synchronously, which can automatically position the offset supercapacitor module 9 to the middle position for automatic adjustment and fixation. When maintenance is required, the cover plate 4 is first opened and the module is removed. At this time, the supercapacitor module 9 is released from the pressure of the pressure plate 11, and the compression spring 24 that was compressed returns to its original position.

[0031] An inner conductive rod 10 is fixed at the center of the slide bar 25. A first elastic contact piece that can move within the mounting base 2 is fixed at the bottom end of the inner conductive rod 10. A slot 5 and a guide groove 6 are provided on the placement plate 32. A second elastic contact piece 7 is fixedly connected in the slot 5. After the supercapacitor module 9 is installed, the conductive rod 8 at the bottom end of the supercapacitor module 9 is inserted into the slot 5 and pressed into contact with the second elastic contact piece 7 to achieve electrical connection.

[0032] Several extension plates 35 are fixedly connected to the side wall of the placement plate 32. The extension plates 35 are located between several positioning clamping arms 30. By setting extension plates 35 on the side wall of the placement plate 32, the area of ​​the placement plate 32 is increased without affecting the positioning clamping arms 30, so as to adapt to supercapacitor modules 9 of different sizes.

[0033] A first protective pad 33 is fixedly connected to the placement plate 32, and a second protective pad 34 is fixedly connected to the end of the positioning clamping arm 30 away from the gear 29. By setting the first protective pad 33 and the second protective pad 34, the protective pads are made of rubber. On the one hand, the protective pads can protect the supercapacitor module when they come into contact with the supercapacitor module, avoiding wear on the supercapacitor module. On the other hand, they can improve friction, thereby preventing the supercapacitor module from shifting when the pressure ring is tightened.

[0034] A third lead screw 22 is fixedly connected to the mounting base 2. The third lead screw 22 is threadedly connected to the first inner groove 20. Several fixed rods 19 arranged at equal intervals are fixedly connected to the mounting base 2. A rotating seat 17 is rotatably connected to the outer end of the module locking seat 16. Fixed feet 18 that slide with several fixed rods 19 are fixedly connected to the side wall of the rotating seat 17. By setting the third lead screw 22, the module locking seat 16 and the third lead screw 22 can be threadedly engaged by rotating the module locking seat 16. At the same time, the rotating seat 17 at the outer end of the module locking seat 16 slides with the fixed rods 19. Therefore, when the module locking seat 16 is rotated, the compressibility of the compression spring 24 can be adjusted, which is conducive to adjusting the required pressure according to the processing needs.

[0035] The working principle and usage process of this invention are as follows: During installation, the supercapacitor module 9 is first placed on the placement plate 32 inside the module locking seat 16, positioning it between multiple ring-shaped positioning clamping arms 30 for pre-positioning; then the cover plate 4 of the main body 1 is closed and fixed by screwing or snap-fitting in the prior art; the pressure plate 11 made of conductive material on the bottom wall of the cover plate 4 is pressed down accordingly; during the pressing process, the supercapacitor module 9 pushes the placement plate 32 and the slide rod 25 fixedly connected to it to slide downward in the first inner groove 20 and the second inner groove 21 of the module locking seat 16, and the limiting plate 23 at the bottom of the slide rod 25 compresses the extrusion spring below it. Spring 24; simultaneously, the rack 31 fixed to the side wall of the slide bar 25 moves downward, driving the gear 29 meshing with it to rotate on the mounting rod 28, thereby causing the L-shaped positioning clamping arm 30 fixed to the outer end of the gear 29 to rotate synchronously towards the center with its mounting rod 28 as the axis, and the second protective pad 34 at its top presses against the outer wall of the supercapacitor module 9 from the side, realizing automatic centering and lateral locking; at the same time, the conductive rod 8 at the bottom of the supercapacitor module 9 is inserted into the slot 5 on the placement plate 32 and makes close contact with the second elastic contact piece 7 in the slot, while the bottom end of the inner conductive rod 10 in the center of the slide bar 25 is in contact with the inner conductive rod 10 in the mounting base 2. The first elastic contact piece makes contact, thus forming a complete electrical connection circuit: the current of the charge / discharge management circuit flows from the DC output interface of the circuit board 3 through the pressure plate 11 into the upper electrode of the supercapacitor module 9, flows out from the conductive plug 8 of its lower electrode inside the module, and flows sequentially through the second elastic contact piece 7, the placement plate 32, the slide rod 25, the inner conductive rod 10 and the first elastic contact piece, and finally flows back to the circuit board 3 to form a charge / discharge circuit; when the power supply is running in a vibrating environment such as in a vehicle or in industry, the continuous clamping force is maintained by the compression spring 24 through the above-mentioned transmission mechanism, thereby resisting vibration impact; when maintenance or replacement of the supercapacitor is required... When module 9 is in use, the cover plate 4 is opened, the pressure of the pressure plate 11 is removed, and the compressed compression spring 24 pushes the limit plate 23 and the slide bar 25 to return to their original position. The slide bar 25 drives the gear 29 to rotate in the opposite direction through the rack 31, causing the positioning clamping arm 30 to unfold outward and release the clamping of the module. At the same time, the placement plate 32 lifts the supercapacitor module 9 upward for easy removal and placement. In addition, by rotating the module locking seat 16 to make it threadedly engage with the third lead screw 22 on the mounting base 2, the overall height of the module locking seat 16 can be adjusted, thereby changing the pre-compression amount of the compression spring 24 to adapt to different models of supercapacitor modules or adjust the required locking pressure.
