Description

Technical Field

[0001] This invention relates to a power conversion device, and more particularly to a ruggedized DC-DC power conversion device for harsh environments, belonging to the technical field of power conversion devices. Background Technology

[0002] A power conversion device is a device that stably converts one DC voltage into another DC voltage; it only converts DC to DC.

[0003] Existing power conversion devices have problems such as being inconvenient to place multiple decorative devices in one device for reinforcement and strengthening during use, and the placement height is also inconvenient to adjust.

[0004] To overcome the problems of existing power conversion devices being inconvenient for reinforcing multiple assembly devices within a single unit and for adjusting the placement height, a ruggedized DC-DC power conversion device for harsh environments is needed, with further improvements and optimizations. Summary of the Invention

[0005] The main objective of this invention is to overcome the problems in the prior art, such as the inconvenience of placing multiple assembly devices in one device for reinforcement and strengthening during use, and the inconvenience of adjusting the placement height, and to provide a ruggedized DC-DC power conversion device for harsh environments.

[0006] The objective of this invention can be achieved by adopting the following technical solution: A ruggedized DC-DC power converter for harsh environments includes a power conversion component body for conversion, wherein the power conversion component body is fixedly connected within a reinforcement body of the conversion device; The four corners of the main body of the conversion device reinforcement are respectively equipped with bottom limit rods, and a screw is rotatably installed inside the bottom limit rod. An assembly limit rod is installed on the top of the screw. The main body of the power converter is fixedly connected to the bottom limit rod and the assembly limit rod at the four corners. A positioning sleeve is fitted on the assembly limit rod of the first set of power converter main bodies. The second set of power converter main bodies is stacked on the positioning sleeve and so on. The main body of the conversion device reinforcement has outer and inner reinforcing ribs distributed on three sides. This structure allows users to flexibly adjust the number of layers in the power conversion component according to actual power requirements, without needing to redesign the overall housing. This significantly improves the adaptability and expandability of the device and reduces the development cost of multi-specification power devices. The outer reinforcing ribs distributed around the three sides of the inner side of the main body of the reinforcement component, together with the detachable inner reinforcing ribs, form a double reinforcement structure of "outer frame + inner support". The outer reinforcing ribs improve the overall rigidity of the shell and prevent deformation; the inner reinforcing ribs can be precisely filled according to the gap between the power conversion component and the shell, forming all-round support for the power conversion component, effectively absorbing vibration and impact, preventing displacement and loosening during operation, and improving the reliability and service life of the device. The four corner assembly limit rods and positioning sleeves work together to provide a precise positioning benchmark for each layer of the power conversion component, avoiding eccentricity and misalignment during stacking and ensuring coaxiality and perpendicularity after multi-layer installation. At the same time, they improve the stability of the overall stacked structure, prevent inter-layer shaking, and ensure the stable operation of the power conversion component.

[0007] Preferably, the inner reinforcing rib within the outer reinforcing rib is a detachable structure. After the power conversion component body is placed inside the conversion device reinforcement body, the inner reinforcing rib is positioned to abut against the gap between the conversion device reinforcement body and the power conversion component body. This close-fitting support between the inner reinforcing rib and the power conversion component body further eliminates installation gaps, ensuring the installation accuracy of the power conversion component. Simultaneously, it reduces the risk of dust and moisture intruding through gaps, improving the protective performance of the device. The inner reinforcing ribs adopt a detachable structure, allowing for flexible selection of appropriate specifications based on actual gaps during installation. No prefabrication is required, resulting in greater adaptability. For subsequent maintenance or replacement of the power converter, only the inner reinforcing ribs need to be removed to take out the power converter, without disassembling the entire housing, which greatly simplifies the maintenance process and reduces maintenance costs.

[0008] Preferably, a limiting rail is installed at one side opening of the main body of the conversion device reinforcement component, and a filler block and a partition are superimposed and installed inside the limiting rail. The filler block and partition inside the limiting rail can precisely fill the opening gap of the main body of the reinforcement component, while simultaneously providing lateral restraint to the main body of the power conversion component, preventing lateral displacement during installation or use. Preferably, the power conversion component body has abutments and heat dissipation vents distributed on it, and the abutments on the first group and the power conversion component body of the second group are separated by a partition structure.

[0009] Preferably, a power conversion interface opening and closing component is installed on one side of the main body of the power conversion component, and the power conversion interface opening and closing component is a flip-opening and closing structure.

[0010] Preferably, the partition is separated by a filler block, and the cavity between the partition and the filler block corresponds to the opening and closing part of the power conversion interface.

[0011] Preferably, the assembly limiting rod is fitted with a positioning sleeve that is adjustable according to the partition height, the four corners of the main body of the conversion device reinforcement are provided with positioning holes, the top of the main body of the conversion device reinforcement is covered with a sealing plate, and the four corners of the sealing plate are provided with connection holes.

[0012] Preferably, the positioning sleeve on the assembly limiting rod is a T-shaped hollow structure, and the bottom limiting rod is placed inside the bottom limiting rod for splicing connection.

[0013] Beneficial technical effects of the present invention: This invention provides a ruggedized DC-DC power conversion device for harsh environments. By using four corner limiting rods and positioning sleeves, the main body of the power conversion component can be stacked in multiple layers. The number of layers can be flexibly adjusted according to power requirements to adapt to different scenarios and reduce development costs.

[0014] The outer reinforcing ribs and the detachable inner reinforcing ribs form a dual support structure, which not only improves the rigidity of the shell, but also accurately fills the gaps for support, effectively resists vibration and prevents loosening, extends the service life of the device, and strengthens the overall rigidity of the equipment.

[0015] The detachable internal reinforcing ribs are highly adaptable and do not require prefabrication. When replacing power components during subsequent maintenance, there is no need to disassemble the entire housing, which greatly simplifies the process and reduces maintenance costs.

[0016] The filler block and partition inside the limit rail eliminate lateral gaps, and the inner reinforcing ribs provide close support, which not only improves installation accuracy but also reduces the intrusion of dust and moisture, thus enhancing protective performance.

[0017] The four corner limit rods and positioning sleeves provide a precise reference for multi-layer installation, avoid eccentricity and misalignment, ensure the coaxiality and stability of the stacked structure, and prevent inter-layer shaking. Attached Figure Description

[0020] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a ruggedized DC-DC power conversion device for harsh environments, including a power conversion component body 2 for conversion, wherein the power conversion component body 2 is fixedly connected inside the conversion device reinforcement component body 1; The four corners of the main body 1 of the conversion device reinforcement are respectively equipped with bottom limit rods 402, and screws 403 are rotatably installed inside the bottom limit rods 402. The top of the screws 403 is equipped with assembly limit rods 401. The power conversion component body 2 is fixedly connected to the bottom limit rod 402 and the assembly limit rod 401 at the four corners. The first set of power conversion component body 2 is fitted with a positioning sleeve 4 on the assembly limit rod 401. The second set of power conversion component body 2 is stacked on the positioning sleeve 4 and so on. The main body 1 of the conversion device reinforcement has an outer reinforcing rib 104 and an inner reinforcing rib 105 distributed on three sides around its inner side.

[0022] The inner reinforcing rib 105 within the outer reinforcing rib 104 is a detachable structure. After the power conversion component body 2 is placed into the conversion device reinforcement component body 1, the inner reinforcing rib 105 is placed to abut against the connection according to the gap between the conversion device reinforcement component body 1 and the power conversion component body 2.

[0023] A limiting rail 3 is installed at one side opening of the main body 1 of the conversion device reinforcement, and a filling block 301 and a partition plate 302 are superimposed and installed inside the limiting rail 3.

[0024] The power conversion component body 2 is provided with abutments 202 and heat dissipation vents 203, and the abutments 202 on the first group and the power conversion component body 2 on the second group are separated by a partition structure.

[0025] A power conversion interface opening and closing component 201 is installed on one side of the power conversion component body 2. The power conversion interface opening and closing component 201 is a flip-opening and closing structure.

[0026] The partition 302 is separated by a filler block 301, and the cavity between the partition 302 and the filler block 301 corresponds to the power conversion interface opening and closing component 201.

[0027] The assembly limiting rod 401 is fitted with a positioning sleeve 4 which is adjusted according to the partition height. The four corners of the main body 1 of the conversion device reinforcement are provided with positioning holes 101. The top of the main body 1 of the conversion device reinforcement is covered with a sealing plate 102, and the four corners of the sealing plate 102 are provided with connecting holes 103.

[0028] The positioning sleeve 4 on the assembly limiting rod 401 is a T-shaped hollow structure, and the bottom limiting rod 402 is placed inside the bottom limiting rod 402 for splicing connection.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, take the main body 1 of the reinforcement component and install the bottom limit rods 402 at the four corner mounting positions respectively. Screw the screw 403 into the bottom limit rod 402 and then fix the assembly limit rod 401 on the top of the screw 403 to complete the pre-installation of the four corner limit components. Check the inside of the main body 1 of the reinforcement component to confirm that the outer reinforcing ribs 104 are distributed around three sides and the inner reinforcing ribs 105 are detachable and will not be installed for the time being. Place the first set of power conversion component body 2 into the reinforcement component body 1, align its four corners with the four corner assembly limit rods 401 respectively, and fix them in place. Observe the gap between the reinforcement component body 1 and the power conversion component body 2. Select the appropriate inner reinforcing rib 105 according to the gap size, embed it into the outer reinforcing rib 104, and press against the power conversion component body 2 to complete the gap filling and support. Place the positioning sleeve 4 on the assembly limiting rod 401 of the first power converter body 2, align the second power converter body 2 with the positioning sleeve 4 and the assembly limiting rod 401, and complete the four-corner fixed connection. Repeat the above operation of placing the positioning sleeve 4 and stacking the power converter body 2 until the required number of layers are installed. A limiting rail 3 is installed at the opening on one side of the main body 1 of the reinforcement component. Based on the remaining space at the opening, a filling block 301 and a partition 302 are sequentially installed inside the limiting rail 3, and the filling opening and the main body 2 of the power conversion component form an operating space.

[0030] Note: Before installation, check all components such as the main body of the reinforcement, limit rod, reinforcing rib, and positioning sleeve to ensure there is no deformation, stripped threads, or dimensional deviation, in order to avoid jamming or positioning failure after installation. After installing the main body of the power conversion component, the gap between it and the main body of the reinforcement component must be accurately measured first, and then the corresponding internal reinforcing ribs should be selected. It is strictly forbidden to forcibly install reinforcing ribs that do not match the size, so as to avoid squeezing and damaging the power component. When stacking power converters, ensure that the positioning sleeves of each layer are fully fitted with the assembly limit rods, and that the force is evenly distributed at the four corners. Avoid eccentricity or misalignment that could cause interlayer shaking or subsequent assembly difficulties. The inner reinforcing ribs must be fully embedded in the outer reinforcing ribs and tightly fitted with the main body of the power converter to prevent loosening, excessive gaps, loss of support and vibration resistance. The filling blocks and partitions in the limit rails must be installed in place to completely fill the opening gaps, preventing lateral displacement of the power components and avoiding excessive compression that could deform the shell.

[0031] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
