Description

Technical Field

[0001] This invention relates to the field of vehicle power supply technology, and in particular to a vehicle power supply with an easy-to-maintain and easy-to-remove mechanism. Background Technology

[0002] A vehicle-mounted integrated power supply is a power distribution system that integrates power generation, charging, and current conversion functions, adapting to the power needs of various types of electronic devices in vehicles. It is widely used in ground vehicles and civilian new energy vehicles, and its core function is to provide stable and efficient power support for various electrical equipment such as observation and targeting equipment, communication systems, and radar, ensuring continuous operation of equipment in complex environments. By integrating multiple input sources, intelligently distributing power, and dynamically adjusting output, it meets the voltage and power requirements of different devices, serving as a core support for the information and intelligent upgrading of modern vehicles.

[0003] Current vehicle power systems have many technical shortcomings: In terms of heat dissipation, traditional power supplies adopt a linear architecture with dense components and long wiring. Heat is easily accumulated during power conversion, and existing heat dissipation structures are unable to quickly dissipate heat. Especially in low-temperature environments or high-load conditions, excessive temperature rise can easily lead to performance degradation. Some power supplies lack targeted thermal management design and have insufficient stability in high-temperature or low-temperature environments.

[0004] In terms of maintenance and testing, traditional power systems are composed of multiple tightly coupled subsystems, with complex structures and close hierarchical relationships. Local faults require shutdown for troubleshooting, making maintenance processes cumbersome and time-consuming. They lack intelligent diagnostic methods, rely on manual offline testing, resulting in low fault detection and isolation rates and easy ambiguity in fault location. They also have low modularity, making component replacement inconvenient and maintenance costs high, making it difficult to meet the needs of rapid maintenance under complex operating conditions.

[0005] With the surge in the number of electronic devices in vehicles, the requirements for power supply stability, adaptability, and maintainability are becoming increasingly stringent. Existing technologies can no longer meet these needs, and there is an urgent need to develop an integrated vehicle power supply system with efficient heat dissipation, intelligent diagnostics, and convenient maintenance features. Summary of the Invention

[0006] The technical problem this invention aims to solve is that current vehicle-mounted cables have limited heat dissipation efficiency and low maintenance and inspection efficiency.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a vehicle power supply with an easy-to-maintain loading and unloading mechanism, including a main housing and several power supply bodies. Several internal support limiting plates for supporting the power supply bodies are fixedly installed inside the main housing. Lateral telescopic openings are symmetrically opened on both sides of the main housing corresponding to the positions of the internal support limiting plates. An electrically controlled flip-closing cover is hinged inside the lateral telescopic opening. An electrically controlled flip detection frame is movably installed inside the electrically controlled flip-closing cover. Electrically controlled translation guide rails are symmetrically opened on the inner wall of the main housing. Electrically controlled magnetic translation blocks are movably installed on the electrically controlled translation guide rails.

[0008] The main housing has symmetrically arranged outer storage slots on both sides of the lateral telescopic opening. The electrically controlled flip-close cover includes a flip-close cover hinged to the lateral telescopic opening and an inner adjusting support rod connected inside the outer storage slot. The extended end of the inner adjusting support rod is movably connected to the flip-close cover, and the angle of the flip-close cover is adjusted by telescoping.

[0009] The internal support limiting plate has an internal heat exchange channel with a serpentine structure, and the outer wall of the main shell has a lateral heat exchange channel with the serpentine structure. The inlet and outlet of the internal heat exchange channel are connected to the lateral heat exchange channels on both sides.

[0010] The flip-close cover plate has a side-sinking groove that cooperates with the electrically controlled flip detection frame.

[0011] The electrically controlled flip detection frame includes a lateral assembly frame fixed on both sides of the side-to-side sinking groove, a flip detection frame body, an embedded motor fixed at both ends of the flip detection frame body, and an embedded optical detection probe. The embedded optical detection probe is fixedly installed on the flip closing cover body and the inner wall of the flip detection frame body.

[0012] The electrically controlled translation guide rail includes an embedded guide rail fixed to the inner wall of the main housing and an electrically controlled lead screw installed inside the embedded guide rail.

[0013] The electrically controlled magnetic translation block includes an internally threaded translation seat threaded onto an electrically controlled lead screw and an elastic electromagnet fixed on the internally threaded translation seat.

[0014] The power supply body has lateral adjustment grooves on both sides of its outer wall, and a sliding telescopic block that cooperates with an elastic electromagnet is slidably assembled inside the lateral adjustment groove.

[0015] The internal threaded translation seat has a laterally open magnetically controlled telescopic groove inside, and the elastic electromagnet includes an electromagnet that is slidably assembled at the opening of the magnetically controlled telescopic groove and an iron spring installed inside the electromagnet.

[0016] The bottom edge of the main housing has a downward-protruding bottom stabilizing bracket, and a bottom liquid cooling tank with internal heat exchanger and circulation pump is installed at the center of the bottom of the main housing.

[0017] The beneficial effects of this invention are:

[0018] (1) The present invention is equipped with an electrically controlled translation guide rail, an electrically controlled magnetic translation block and a sliding telescopic block of the power supply body to realize the electrically controlled loading and unloading of the power supply body. No manual plugging and unplugging is required, which greatly improves the loading and unloading efficiency of the power supply body and reduces the operating intensity of maintenance personnel. At the same time, the magnetic connection method combined with the elastic structure ensures stable connection and no hard wear during disassembly and assembly, thus extending the service life of the equipment.

[0019] (2) The electrically controlled flip-closing cover can realize the electrically controlled opening and closing of the lateral telescopic port, and the opening and closing angle can be flexibly adjusted by the inner adjusting support rod. It provides sufficient operating space and bottom support for the installation and removal of the power supply body, and can also achieve the sealing protection of the lateral telescopic port when the equipment is running normally, so as to prevent dust, water vapor and other impurities from entering the main shell and affecting the operation of the equipment.

[0020] (3) The electrically controlled flip detection frame integrates an embedded optical detection probe, which can realize online non-contact detection while the power supply body moves outward. Fault diagnosis can be completed without manually disassembling the power supply body. The detection angle can be flexibly adjusted by the embedded motor, and the detection range is fully covered, which greatly improves the efficiency and accuracy of fault detection and realizes rapid fault location and isolation.

[0021] (4) The internal heat exchange channel and the side heat exchange channel with the bottom liquid cooling box are combined to form a closed-loop liquid cooling heat dissipation system. The serpentine layout of the heat exchange channel greatly increases the heat exchange contact area. The heat dissipation liquid is driven by the circulating pump to achieve rapid circulation, which can quickly remove the heat generated by the power supply body. This effectively solves the problem of heat accumulation in traditional vehicle power supplies and improves the operating stability of the equipment under high load and extreme temperature conditions.

[0022] (5) The overall equipment adopts an electronic control design, each functional component is independently assembled and electronically controlled in linkage. The structure is compact and reasonable. The bottom stable support improves the stability of the equipment under vehicle bumpy conditions. The linkage control of each electronic control component realizes the intelligent operation of the equipment, which is adapted to the intelligent development needs of modern vehicles.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The vehicle-mounted power supply with an easy-to-maintain loading and unloading mechanism described in this invention has a main housing 1 as the mounting support base for the entire device. The main control module 18 integrated inside is electrically connected to the electrically controlled flip-closing cover 5, the electrically controlled flip detection frame 6, the electrically controlled translation guide rail 7, the electrically controlled magnetic translation block 8, and the circulation pump in the bottom liquid cooling box 17, realizing centralized control and linkage operation of each electronic control component. The bottom stabilizing bracket 16 is an integrally formed structure with the main housing 1 and is distributed around the bottom perimeter of the main housing 1 to improve the placement stability of the device under vehicle bumpy conditions. The internal support limiting plate 3 is made of hard thermally conductive metal and is welded and fixed to the inside of the main housing 1. Several internal support limiting plates 3 are equidistantly arranged along the length of the main housing 1 to form several support positions for the power supply body 2, realizing the modular assembly of the power supply body 2.

[0034] One side of the flip-closed cover body 51 is hinged to the edge of the lateral telescopic opening 4. The outer storage groove 9 is symmetrically opened on the upper and lower sides of the lateral telescopic opening 4. One end of the inner adjusting support rod 52 is hinged to the inner wall of the outer storage groove 9, and the other end is movably hinged to the inner wall of the flip-closed cover body 51. The inner adjusting support rod 52 is an electric telescopic rod. The telescopic movement of its telescopic end can drive the flip-closed cover body 51 to flip around the hinge point.

[0035] The lateral sinking groove 12 is located at the center of the flip-closed cover plate body 51. The lateral assembly frame 61 is welded and fixed to the inner walls of both sides of the lateral sinking groove 12. The embedded motor 63 is bolted to the end of the lateral assembly frame 61. Its output end passes through the lateral assembly frame 61 and is connected to the end of the flip detection frame 62. The embedded optical detection probe 64 is evenly distributed on the inner wall of the flip detection frame 62 and the inner wall of the flip-closed cover plate body 51. It is bolted to the flip detection frame 62 and electrically connected to the main control module 18.

[0036] The embedded guide rail 71 is bolted to the inner wall of the main housing 1 and is symmetrically distributed on both sides inside the main housing 1. The two ends of the electric control screw 72 are rotatably connected to the ends of the embedded guide rail 71 through bearings. One end of the electric control screw 72 is connected to a drive motor, which is electrically connected to the main control module 18. The inner side of the internal threaded translation seat 81 is provided with a slot that matches the embedded guide rail 71 and slides and engages with the embedded guide rail 71. The center of the internal threaded translation seat 81 is provided with a threaded hole that engages with the threaded sleeve of the electric control screw 72. The magnetic control telescopic groove 15 of the elastic electromagnet 82 is opened on the outer wall of the internal threaded translation seat 81. The electromagnet body 821 is slidably sealed with the magnetic control telescopic groove 15. The iron spring 822 is nested inside the magnetic control telescopic groove 15, and its two ends abut against the inner wall of the magnetic control telescopic groove 15 and the inner wall of the electromagnet body 821, respectively. The electromagnet body 821 is electrically connected to the main control module 18.

[0037] Lateral adjustment slots 13 are symmetrically opened on both outer walls of the power supply body 2. The sliding telescopic block 14 is made of magnetic metal and is slidably assembled with the lateral adjustment slot 13. A return spring is provided between the sliding telescopic block 14 and the inner wall of the lateral adjustment slot 13 to realize the elastic extension and retraction of the sliding telescopic block 14. When the electromagnet body 821 is energized, it generates magnetic force, which can attract the sliding telescopic block 14 to extend along the lateral adjustment slot 13 and fit against the electromagnet body 821, realizing the fixed cooperation between the power supply body 2 and the electrically controlled magnetic translation block 8.

[0038] The internal heat exchange channel 10 is located inside the internal support limiting plate 3 and has a serpentine through structure. Its inlet and outlet both extend to the inner wall of the main shell 1. The lateral heat exchange channel 11 is located inside the outer wall of the main shell 1 and also has a serpentine through structure. Its two ends are sealed and connected to the inlet and outlet of the internal heat exchange channel 10, respectively. The bottom liquid cooling box 17 is bolted to the bottom of the main shell 1. Its internal circulation pump is electrically connected to the main control module 18. The outlet of the bottom liquid cooling box 17 is sealed and connected to the inlet of the lateral heat exchange channel 11, and the inlet is sealed and connected to the outlet of the lateral heat exchange channel 11, forming a closed-loop liquid cooling heat dissipation channel.

[0039] This invention uses the main control module 18 as the control core and achieves three core functions—precise magnetic control loading and unloading, online optical inspection, and closed-loop liquid cooling—through the coordinated operation of the electronic control components. Magnetic control translation achieves precise positioning through lead screw transmission and guide rail guidance; optical inspection achieves fault diagnosis through non-contact optical imaging and feature recognition; and liquid cooling achieves rapid heat removal through efficient heat exchange in a serpentine flow channel. Each functional module operates independently and can be coordinated and controlled through the main control module 18, thus realizing the intelligent, modular, and easy-to-maintain operation of the vehicle power supply as a whole.

[0040] The core positioning principle of magnetic translation is the screw and nut drive + guide rail sliding engagement, which, together with the pulse number control of the main control module 18, realizes the linear precise positioning of the electrically controlled magnetic translation block 8. The positioning accuracy is determined by the lead of the electrically controlled screw 72 and the pulse number of the drive motor.

[0041] Key positioning parameters: The lead of the electric control screw 72 is 5mm, the matching drive motor is a stepper motor with a step angle of 1.8°, a single pulse corresponds to 0.01 rotations of the electric control screw 72, and the corresponding translation distance of the internal thread translation seat 81 is 0.05mm. The overall magnetic control translation positioning accuracy is ±0.05mm; the straightness error of the embedded guide rail 71 is ≤0.02mm / m, ensuring the straightness of the translation process.

[0042] Positioning control principle: The main control module 18 sends a specified number of pulse signals to the stepper motor of the lead screw 72 according to the assembly station coordinates of the power supply body 2. The stepper motor completes the rotation of the corresponding angle according to the number of pulses, driving the lead screw 72 to rotate. Through the threaded engagement of the lead screw nut, the rotational motion of the lead screw 72 is converted into the linear translational motion of the internal thread translation seat 81. At the same time, the sliding engagement between the internal thread translation seat 81 and the embedded guide rail 71 restricts the rotational motion of the internal thread translation seat 81, retaining only the linear translational freedom along the embedded guide rail 71, realizing the guiding limit during the translation process and avoiding deviation.

[0043] The operation process of magnetic control: When it is necessary to cooperate with the power supply body 2, the main control module 18 sends an energizing signal to the electromagnet body 821. The electromagnet body 821 is energized and generates magnetic force. Under the action of magnetic force, it overcomes the elastic force of the iron spring 822 and slides into the magnetic control telescopic groove 15. At the same time, the sliding telescopic block 14 that attracts the power supply body 2 extends along the lateral adjustment groove 13, so that the sliding telescopic block 14 and the electromagnet body 821 fit tightly and are inserted into the magnetic control telescopic groove 15, thereby fixing the power supply body 2 and the electrically controlled magnetic translation block 8. When it is necessary to disengage, the main control module 18 cuts off the power supply to the electromagnet body 821. The magnetic force disappears, and the elastic force of the iron spring 822 pushes the electromagnet body 821 to retract to the opening position of the magnetic control telescopic groove 15. At the same time, it squeezes the sliding telescopic block 14 to reset and retract in the lateral adjustment groove 13, thereby separating the two.

[0044] The core principle of optical inspection is machine vision optical imaging + fault feature recognition. The embedded optical inspection probe 64 collects optical images of the surface and interface of the power supply body 2 and transmits them to the main control module 18 for image preprocessing and fault feature matching, so as to realize online non-contact fault detection of the power supply body 2. It can detect fault types such as appearance damage, interface oxidation, and abnormal heating of the power supply body 2.

[0045] Key detection parameters: The embedded optical detection probe 64 is an industrial high-definition CMOS camera with a pixel resolution of 2 million, an acquisition frame rate of 30fps, a detection focal length of 50-200mm, a detection field of view of 60°, a detection distance of 10-50cm, and an image transmission rate of 100Mbps; the embedded motor 63 is a servo motor with a rotation accuracy of ±0.1°, which can drive the flip detection frame 62 to achieve a 0-180° flip adjustment; the detection response time is ≤1s, and the fault identification accuracy is ≥98%.

[0046] Detection process:

[0047] Detection Start: After receiving the detection command, the main control module 18 sends a telescopic signal to the inner adjusting support rod 52. The inner adjusting support rod 52 extends and pushes the flip-closed cover body 51 to flip around the hinge point to a preset angle. The preset detection opening and closing angle is 90°, so that the side telescopic port 4 is fully opened, providing an unobstructed view for detection.

[0048] Angle adjustment: The main control module 18 sends a rotation signal to the embedded motor 63, which drives the flip detection frame 62 to flip within the side assembly frame 61 until it is vertically upward, so that the lens of the embedded optical detection probe 64 is aligned with the detection area of ​​the power supply body 2 to be tested. The flip angle can be adjusted according to the detection requirements to achieve full-angle detection of the front, side and interface of the power supply body 2.

[0049] Image acquisition: The embedded optical detection probe 64 acquires optical images of the power supply body 2 at a frame rate of 30fps, and transmits the images to the main control module 18 in real time via a data cable;

[0050] Fault identification: The main control module 18 has a built-in fault feature database. After preprocessing the acquired images such as noise reduction, enhancement, and segmentation, it matches them with fault features in the database, such as damage, oxidation, and bulging. If the match is successful, it is determined to be the corresponding fault type and the fault information is fed back to the external terminal.

[0051] Detection and Reset: After the detection is completed, the main control module 18 sends a reset signal to the embedded motor 63, and the flip detection frame 62 is reset into the side sinking groove 12, keeping it in contact with the flip closing cover body 51; then the inner adjusting support rod 52 retracts, driving the flip closing cover body 51 to reset, realizing the sealing and closure of the side telescopic port 4.

[0052] The core principle of the heat dissipation system is the circulation of heat transfer medium. The internal support limiting plate 3 made of hard thermally conductive metal is used to conduct the working heat of the power supply body 2 to the internal heat exchange channel 10. Driven by the circulation pump in the bottom liquid cooling box 17, the heat transfer fluid circulates in the serpentine structure of the internal heat exchange channel 10 and the side heat exchange channel 11. The side heat exchange channel 11 is staggered and arranged on both sides of the main shell 1. Then the heat is carried out to the outside of the main shell 1, so as to achieve continuous cooling of the power supply body 2.

[0053] Core heat dissipation parameters: The heat dissipation fluid in the bottom liquid cooling tank 17 is an ethylene glycol aqueous solution with a volume concentration of 50% and an applicable temperature range of -30℃ to 100℃; the rated flow rate of the circulating pump is 8L / min and the rated head is 5m; the inner diameter of the internal heat exchange channel 10 and the side heat exchange channel 11 is 8mm, and the total heat exchange area of ​​the serpentine channel is 0.8m²; the heat dissipation power of the heat dissipation system is ≥500W, which can control the operating temperature of the power supply body 2 within the rated range of -20℃ to 60℃.

[0054] Heat dissipation operation process:

[0055] After the equipment is powered on, the main control module 18 sends a start signal to the circulation pump in the bottom liquid cooling tank 17, and the circulation pump starts to work.

[0056] The heat generated by the power supply body 2 during operation is directly conducted to the internal support limiting plate 3 that is attached to it. The internal support limiting plate 3 is made of hard thermally conductive metal with a thermal conductivity ≥400W / (m・K), which quickly conducts the heat to the inner wall of the internal heat exchange channel 10.

[0057] The circulating pump pumps the low-temperature heat exchange liquid in the bottom liquid cooling tank 17 from the outlet end into the lateral heat exchange channel 11. The low-temperature heat exchange liquid flows along the serpentine structure of the lateral heat exchange channel 11 to the inner heat exchange channel 10, where it exchanges heat with the inner wall of the inner heat exchange channel 10 and becomes a high-temperature heat exchange liquid after absorbing heat. The high-temperature heat exchange liquid flows back from the outlet of the inner heat exchange channel 10 to the lateral heat exchange channel 11 on the other side for external heat dissipation. Then, the cooled low-temperature heat exchange liquid is introduced upward into the upper inner heat exchange channel 10, and then until it reaches the innermost inner heat exchange channel 10. Finally, it flows back to the inlet end of the bottom liquid cooling tank 17 through the longitudinal return channel on the side wall of the main shell 1, completing the circulating liquid cooling operation.

[0058] The loading and unloading of the power supply unit 2 is based on the precise positioning of the electrically controlled magnetic translation block 8. Through the linkage control of the main control module 18, the loading and unloading is automated without manual intervention. The entire process is completed by the main control module 18 according to the preset program. The loading and unloading time of a single power supply unit 2 is ≤30s, which is divided into two processes: installation and disassembly.

[0059] Power supply unit installation process:

[0060] Workstation opening: The main control module 18 controls the inner adjusting support rod 52 to extend, flips the closed cover plate body 51 to rotate 90°, and opens the lateral telescopic port 4; at the same time, it controls the electric control screw 72 to rotate, and moves the electric magnetic translation block 8 to the outer workstation of the lateral telescopic port 4 with a positioning accuracy of ±0.05mm.

[0061] Magnetic reset: The main control module 18 controls the electromagnet body 821 to be de-energized, and the iron spring 822 pushes the electromagnet body 821 to the opening position of the magnetic telescopic groove 15.

[0062] Docking and positioning: The power supply body 2 is inserted from the side telescopic port 4 so that the side adjustment slots 13 on both sides of the power supply body 2 are precisely aligned with the position of the electromagnet body 821 of the electrically controlled magnetic translation block 8. The main control module 18 achieves precise docking through the fine adjustment of the electrically controlled lead screw 72.

[0063] Magnetic control fixation: The main control module 18 controls the electromagnet body 821 to be energized, adsorbs the sliding telescopic block 14 to extend and fit with the electromagnet body 821, and synchronously brings the sliding telescopic block 14 into the magnetic telescopic groove 15, thereby fixing the power supply body 2 and the electrically controlled magnetic translation block 8.

[0064] Workpiece delivery: The main control module 18 controls the electric control screw 72 to rotate, which drives the internal thread translation seat 81 to move along the embedded guide rail 71, accurately delivering the power supply body 2 to the preset support position of the internal support limit plate 3, and completing the positioning and placement.

[0065] Sealing and closing: The magnetically controlled translation block 8 is reset, the main control module 18 controls the inner adjusting support rod 52 to retract, the flip-closed cover plate body 51 is reset, the lateral telescopic port 4 is sealed, and the installation is completed.

[0066] Power supply unit disassembly process:

[0067] Workstation opening: The main control module 18 controls the inner adjusting support rod 52 to extend and open the lateral telescopic port 4; at the same time, it controls the electric control screw 72 to rotate and accurately move the electric magnetic translation block 8 to the assembly station of the power supply body 2 to be disassembled, so as to achieve precise docking between the electromagnet body 821 and the sliding telescopic block 14.

[0068] Magnetic control fixation: The main control module 18 controls the electromagnet body 821 to be energized, adsorbing the sliding telescopic block 14, thereby fixing the power supply body 2 and the electrically controlled magnetic translation block 8.

[0069] Workstation extraction: The main control module 18 controls the electric control screw 72 to rotate in the opposite direction, driving the internal thread translation seat 81 to move along the embedded guide rail 71 towards the lateral telescopic port 4, so as to accurately extract the power supply body 2 from the support workstation of the internal support limit plate 3.

[0070] Magnetic separation: When the power supply body 2 is moved to the outer work position of the lateral telescopic port 4, the main control module 18 controls the electromagnet body 821 to be de-energized, the magnetic force disappears, and the electromagnet body 821 separates from the sliding telescopic block 14.

[0071] Removal and Reset: Take the power supply body 2 out from the side telescopic port 4. The main control module 18 controls the electric control screw 72 to rotate, driving the electric magnetic translation block 8 to reset to the initial position. Then, control the inner adjusting support rod 52 to retract, sealing the side telescopic port 4, and the disassembly is completed.
