Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment, and more particularly to a micro power supply applied to a minimalist base station. Background Art

[0002] In existing communication base station power supply systems, micro power sources are typically fixed to piles or electrical boxes using a wall-mounted assembly method, forming a continuous power supply network through distributed layout. For example, the invention patent with announcement number CN117040057B discloses a household wall-mounted energy storage power source, whose technical solution includes: an energy storage power source body, an upper mounting hole, matching bearings, a rotating threaded rod, a limit block and other structural components, and the device is wall-mounted by threaded fastening.

[0003] However, this technical solution has the following significant defects in actual engineering applications:

[0004] Safety hazards of working at height: When the equipment is installed in a suspended high position (such as an electrical box over 5 meters high), maintenance or replacement requires workers to climb to a high place and perform complex operations such as unpacking, unlocking tools (such as disassembly with a screwdriver), and taking and placing equipment. This results in prolonged stay time at height and a significantly increased risk of falling.

[0005] Low operational efficiency: Traditional threaded fastening structures rely on manual removal and installation of screws one by one, and single maintenance takes up to 15 to 30 minutes, seriously affecting base station operation and maintenance efficiency.

[0006] Insufficient emergency response capabilities: In the event of a sudden failure, the cumbersome disassembly process delays equipment replacement and may cause power supply network interruption, which does not meet the "minute-level" emergency maintenance requirements for communication base stations.

[0007] It is particularly noteworthy that the installation structure of existing wall-mounted power supplies does not take into account the particularity of high-altitude scenarios and lacks a quick disassembly and assembly mechanism, resulting in high operation and maintenance costs and safety risks. Therefore, it is urgent to develop a base station micro power supply installation solution that supports quick disassembly and assembly to solve the above technical pain points.

[0039] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The micro power supply for a minimalist base station involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Reference Figures 1-12 The present invention provides a micro power supply for use in a minimalist base station, comprising a power supply cabin 1, a hatch of the power supply cabin 1 being hinged with a left-right symmetrically arranged double-door 2, a power supply base 4 being installed on the rear side wall of the inner cavity of the power supply cabin 1, and a storage power supply 3 electrically connected to the power supply base 4 being provided on the front side; the outer periphery of the storage power supply 3 is detachably covered with a constraint frame 5, and the left and right ends of the constraint frame 5 are respectively installed with symmetrically arranged telescopic guide assemblies 6, and the ends of the telescopic guide assembly 6 form abutment with the guide rails 7 provided on the left and right side walls of the power supply cabin 1, and the retractable assemblies 8 are symmetrically assembled on the upper and lower sides of the inner cavity of the power supply cabin 1, and the retractable assembly 8 is detachably connected to the constraint frame 5 through a connector 9, and except for the back side of the power supply cabin 1, two groups of traction assemblies 10 distributed up and down are symmetrically assembled on its circumferential periphery, and a push-pull device for driving the retractable assembly 8 to perform shape transformation is also provided in the rear cavity of the power supply cabin 1.

[0041] In this embodiment, it should be specifically noted that a fastening ring 11 is fixed to the back side of the power supply compartment 1. The end of the fastening ring 11 extends out of the power supply compartment 1 and is provided with an elastically expandable notch. The power supply compartment 1 is injection-molded using a high-toughness engineering aluminum alloy. The notch can be elastically deformed to adapt to columns of different diameters. The radial locking force is applied by fastening bolts on both sides of the notch to achieve rigid fixation of the device at any height position of the column.

[0042] The front cavity of the power supply compartment 1 is provided with a flared area, the front inner width of which is at least greater than the inner width of the rear cavity; the guide rails 7 extend outwardly parallel to the side walls of the power supply compartment 1, forming an outwardly flared section in the flared area, thereby increasing the spacing between the guide rails 7 on both sides; this enables the telescopic guide assembly 6 to elastically extend and retract along the guide rails 7: in the rear cavity of the power supply compartment 1, it is in a condensed state, closely adhering to the guide rails 7, and when entering the flared area, it adaptively extends outward, significantly reducing the pressure between the two and providing lateral operating space for disassembly and assembly of the constraint frame 5;

[0043] A dynamic fit gap is provided between the outer side of the energy storage power source 3 and the inner cavity of the power source chamber 1. The telescopic guide assembly 6, the connector 9 and the retractable assembly 8 are integrated and installed in this space. The layout satisfies the freedom of movement and interference margin required for the coordinated action of the three.

[0044] The power supply base 4 is provided with a power transmission end and a charging end, and an electrical interface for docking is provided between the energy storage power supply 3 and the power supply base 4;

[0045] The bottom of the power supply base 4 adopts a dual-mode power supply design:

[0046] Transmission end: connected to the electrical equipment through a standardized connector (model: IEC 60320-C13), outputting an alternating current with a rated voltage of 220V±5% / 50Hz;

[0047] Charging end: Equipped with an MC4 photovoltaic interface, it supports docking with a photovoltaic array with a maximum open-circuit voltage of 42V. It has a built-in MPPT charging controller (conversion efficiency ≥ 97%) to achieve maximum power point tracking and storage of photovoltaic power.

[0048] The electrical interface between the energy storage power supply 3 and the power supply base 4 adopts an anti-misinsertion structure (compliant with IP67 protection level), and its electrical parameters are:

[0049] Interface model: Anderson Powerpole SB120

[0050] Rated current: 120A DC / 240A peak

[0051] Contact impedance: ≤0.5mΩ

[0052] Plug and unplug life: 10,000 cycles;

[0053] The push-pull device uses a linear drive mechanism, specifically composed of a servo motor, a lead screw, and a limit slider: the servo motor drives the lead screw to rotate through a coupling, and the limit slider (pre-tightened and anti-backlash treated) mounted on the lead screw is rigidly connected to the distance beam 806, converting the motor's rotational torque into linear motion of the slider (the direction of motion is parallel to the lead screw axis), thereby accurately controlling the forward / reverse displacement of the distance beam 806, and further driving the retractable assembly 8 to complete the specified shape-changing action; the push-pull device can be replaced with other drive mechanisms with equivalent functions;

[0054] In this article, all the positional relationships we discuss about front, back, left, and right are based on Figure 1-Figure 3 These directions are defined by the perspective presented. They have no actual geographical or physical meaning. They are merely a reference framework to help readers understand the content of the article more intuitively. In this way, we can more clearly show the relative position relationship between the various parts, making the entire discussion process easier to understand and follow. Please note that this custom direction identification is only for internal use in this article and does not represent any absolute direction or position in the real world.

[0055] Reference Figure 3-Figure 5 The telescopic guide assembly 6 includes an arm tube 601, a telescopic arm 602, a roller 603 and an elastic member 604, wherein the bottom plate of the arm tube 601 is installed on the left and right sides of the constraint frame 5, and can be fixed to the side wall of the outer frame 501 by bolts. The telescopic arm 602 is movably inserted into one end of the tube cavity of the arm tube 601, and the telescopic arm 602 is elastically connected to the elastic member 604 built into the arm tube 601. The end of the telescopic arm 602 away from the elastic member 604 is equipped with a roller 603.

[0056] In this embodiment, it should be specifically explained that the roller 603 is embedded in the guide rail 7 to form a stable sliding fit, achieve precise guidance, and ensure that the roller 603 does not undergo radial displacement or axial derailment during movement. At the same time, the assembly interface between the telescopic arm 602 and the roller 603 is provided with an anti-loosening structure to maintain connection reliability.

[0057] Reference Figure 2-Figure 4 、 Figure 6-Figure 12 The energy storage power supply 3 is enclosed and locked by two symmetrically arranged constraint frames 5. Each constraint frame 5 is composed of an outer frame 501, an isolation layer 502, and a connecting seat 503. The inner wall of the outer frame 501 is fixedly connected to the isolation layer 502 to form a bearing structure. The top and bottom end surfaces of the outer frame 501 are respectively rigidly connected to the connecting seat 503 through fasteners.

[0058] The retracting and unfolding assembly 8 is composed of a swing arm 801, a positioning shaft 802, a sliding sleeve 803, an angle adjustment shaft 804, a driving arm 805 and a distance beam 806, wherein the swing arm 801 is arranged crosswise up and down and is hinged through the positioning shaft 802 at its rear end, and the positioning shaft 802 is fixedly mounted on the upper and lower walls of the power supply cabin 1; the outer end of the swing arm 801 extends into the slide groove of the side wall of the power supply cabin 1 and can move along the slide groove, and a sliding sleeve 803 is sleeved on its surface and can slide axially along the swing arm 801, and the side of the sliding sleeve 803 close to the energy storage power supply 3 is rotatably connected to the angle adjustment shaft 804, and the surface of the angle adjustment shaft 804 is fixedly connected to the driving arm 805 extending to the connecting piece 9, and the angle adjustment shafts 804 arranged symmetrically on the left and right are connected by the distance beam 806, and the distance beam 806 and the driving arm 805 form a triangular frame, and the outer end of the driving arm 805 is rigidly connected to the connecting piece 9;

[0059] In this embodiment, it should be specifically noted that the isolation layer 502 adopts a semi-enclosed structure to cover and adhere to the circumferential side wall of the energy storage power supply 3, and is made of an insulating flexible material, specifically silicone rubber or polyvinyl chloride;

[0060] The length of the slideway of the power supply cabin 1 at least covers the circumferential motion radius of the swing arm 801 when it rotates around the positioning axis 802 to prevent interference during the movement of the mechanism. At the same time, the movable connection between the sliding sleeve 803 and the angle adjustment shaft 804 is preferably a rotating card-type structure. This design allows the sliding sleeve 803 to achieve adaptive angle adjustment, thereby accurately driving the cross-arranged swing arms 801 to dynamically converge toward the centerline of the device.

[0061] The connecting member 9 is composed of a buckle base 901 and a telescopic member 902. The buckle base 901 is fixedly connected to the telescopic member 902 at the end adjacent to the driving arm 805, and a buckle is provided on the other side to engage with the slot of the connecting seat 503.

[0062] The telescopic member 902 is configured as a plug-in double-tube body, which can realize relative telescopic movement within a quantitative stroke range; with the help of the connection between the telescopic member 902 and the drive arm 805, longitudinal displacement conditions can be created for the buckle base 901 to detach from the connecting seat 503.

[0063] Reference Figure 1-Figure 2 Each traction assembly 10 is symmetrically distributed along the center line of the power cabin 1, and its structure includes a fixed pulley 1001, a transition frame 1002 and a jumper cable 1003, wherein the fixed pulley 1001 is respectively arranged on the side of the flip node of the split hatch 2 and the power cabin 1 and on the rear side of the swing arm 801, and maintains a height difference with the swing arm 801; the transition frame 1002 is located on the transition path from the fixed pulley 1001 to the plane where the swing arm 801 is located; one end of the jumper cable 1003 is fixed to the split hatch 2, and the other end passes through multiple fixed pulleys 1001 and the transition frame 1002 in sequence and is connected to the outer end of the swing arm 801.

[0064] In this embodiment, it should be specifically explained that a rebound mechanism is provided between the double-leaf door 2 and the inner corner of the power supply compartment 1 , and the rebound mechanism is specifically a tension spring structure.

[0065] Working principle of the present invention:

[0066] The device has two working modes: power supply mode (corresponding to Figures 1-6 The structure shown) and disassembly mode (corresponding to Figure 7-12 The structural morphology shown);

[0067] In the power supply mode, the sleeve 803 slides along the surface of the swing arm 801 to the rear end position, and the two cross-stacked swing arms 801 are unfolded to the maximum inner angle state; the driving arm 805 drives the energy storage power supply 3 assembled inside the constraint frame 5 to fit tightly against the front side of the power supply base 4 through the traction action of the connector 9. At this time, the electrical interface arranged flush with the contact surface of the energy storage power supply 3 and the power supply base 4 forms a tight series connection, constructing a stable power supply circuit system; at the same time, the front end of the swing arm 801 swings to the rear end position of the slide groove of the power supply cabin 1, and no traction tension is applied to the cross-cable 1003, so that the double-door 2 remains closed under the action of the rebound mechanism, and the front end of the hatch of the power supply cabin 1 is completely closed, thereby realizing the protection function of the internal components of the power supply cabin 1;

[0068] When the equipment needs to be disassembled, repaired or replaced with a new battery, the equipment will switch from the power supply mode to the disassembly mode, and the output end of the push-pull device drives the fixed-distance beam 806 to move forward, which forms a rigid triangular frame with the driving arms 805 on both sides through the angle adjustment shaft 804, and pulls the constraint frame 5 and the energy storage power supply 3 locked inside it forward as a whole through the vertically arranged connecting piece 9. At the same time, the sleeve 803 can rotate relatively around the top of the angle adjustment shaft 804, and the telescopic guide assembly 6 can be displaced in the same direction as the constraint frame 5, forming an integrated motion system of the fixed-distance beam 806, the angle adjustment shaft 804, the sleeve 803, the driving arm 805, the connecting piece 9, the constraint frame 5, the energy storage power supply 3 and the telescopic guide assembly 6, so as to realize the automatic disconnection of the electrical interface between the energy storage power supply 3 and the power supply base 4 and cut off the circuit; during the movement, the sleeve 803 adaptively adjusts and The switching angle of the angle adjustment shaft 804 causes the left and right crossed swing arms 801 to converge toward the center line with the positioning shaft 802 as the axis, and the internal angle thereof continues to decrease, that is, the swing arm 801 swings along the slide groove toward the front cavity of the power supply cabin 1, causing the bridging cable 1003 that successively crosses the transition frame 1002 and the fixed pulley 1001 to overcome the elastic resistance and pull the split hatch 2 outward; during this period, the roller 603 end of the telescopic arm 602 abuts the guide rail 7, and the other end compresses the elastic member 604 in the arm tube 601, and uses the elastic potential energy to constrain the displacement trajectory of the energy storage power supply 3 to ensure that it is aligned with the electrical interface dimension of the power supply base 4; when the internal angle of the swing arm 801 reaches the minimum value, the energy storage power supply 3 is precisely positioned to the front end flared area of ​​the power supply cabin 1, the split hatch 2 is fully unfolded, the telescopic guide assembly 6 enters the outward expansion section of the guide rail 7, and the system completes the mode switching and enters the state to be disassembled;

[0069] In the disassembly and assembly mode, the telescopic arm 602 is driven by the elastic force of the elastic member 604 to drive the roller 603 to extend outward and adaptively abut the extended section of the guide rail 7, providing lateral operation space for the disassembly and assembly of the constraint frame 5; then the operator pulls the buckle base 901 away from the connecting seat 503, and with the help of the connection between the telescopic member 902 and the driving arm 805, the longitudinal displacement condition can be created for the buckle base 901 to detach from the connecting seat 503; when the connecting member 9 is unlocked, the energy storage power supply 3 locked in the constraint frame 5 remains in a hovering position through the telescopic guide assembly 6; finally, the connecting bolts between the outer frame 501 are removed, and the constraint frame 5 outside the energy storage power supply 3 is removed to complete the inspection or replacement, and the equipment is switched from the disassembly and assembly mode to the power supply mode according to the reverse operation process until the initial operation state is restored.

[0070] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, these should be included under the protection of the present invention.
