Description

Technical Field

[0001] This utility model relates to a heat dissipation structure, specifically a heat dissipation structure for a vehicle-mounted mobile energy storage cabinet, belonging to the technical field of mobile energy storage cabinets. Background Technology

[0002] Pickup trucks, with their advantages of maneuverability, strong off-road capability, and adaptable cargo bed load capacity, have become one of the core carriers for mobile energy storage cabinets. The mobile energy storage cabinet is installed at the rear of the pickup truck bed and houses a lithium-ion battery pack as the core of energy storage. In non-working or charging scenarios, external power is connected through the energy storage cabinet's charging interface. The electrical energy is converted into a suitable charging current and voltage for the battery pack by the internal charging management module and gradually stored in the individual battery cells. The battery management system monitors the voltage, charge, and temperature of each battery cell in real time to prevent overcharging and ensure that the battery pack completes energy storage safely, reserving energy for subsequent power supply.

[0003] For example, patent CN216794324U discloses a portable energy storage cabinet for power inspection vehicles. Although this patent achieves fixed mounting of the energy storage cabinet and the power inspection vehicle through connecting components, it does not include targeted auxiliary heat dissipation components. When the mobile energy storage cabinet is installed in the truck bed, the open structure of the truck bed exposes it directly to the complex environment. Under the summer sun, a high-temperature sealed space can easily form inside the truck bed. Coupled with the concentrated heat generated by the battery pack when the energy storage cabinet is powered under high load, relying solely on natural ventilation is not enough to dissipate the heat in time. This will not only lead to a sharp drop in battery charging and discharging efficiency and frequent high-temperature failures of the equipment, but also, with long-term operation, may cause battery thermal runaway due to heat accumulation, posing a serious safety hazard. Summary of the Invention

[0004] The purpose of this utility model is to provide a heat dissipation structure for a vehicle-mounted mobile energy storage cabinet in order to solve the above problems. The support frame forms a lateral ventilation gap between the energy storage cabinet and the support frame. When the motor drives the fan to run, the external cold air can quickly enter the mounting frame through the gap of the support frame, and then be introduced into the interior of the energy storage cabinet through the heat dissipation cover plate. The internal hot air is discharged in the opposite direction through the heat dissipation cover plate and the mounting frame, and is quickly diffused with the help of the ventilation space formed by the support frame, so as to avoid the accumulation of hot air on the side wall of the energy storage cabinet.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a heat dissipation structure for a vehicle-mounted mobile energy storage cabinet, comprising an energy storage cabinet and a support mechanism installed at the bottom of the energy storage cabinet, a protective mechanism fixed on the support mechanism, and two support frames symmetrically fixed on the protective mechanism. The heat dissipation mechanism is characterized in that: a heat dissipation mechanism is installed on the part of the energy storage cabinet near the support frame, the heat dissipation mechanism including a heat dissipation cover plate and a mounting frame; the heat dissipation cover plate is fixedly installed on the side wall of the energy storage cabinet near the support frame by bolts; the heat dissipation cover plate communicates with the interior of the energy storage cabinet; two mounting frames are symmetrically fixedly connected to the heat dissipation cover plate; the mounting frames communicate with the interior of the energy storage cabinet; a motor is fixedly installed inside the mounting frame; and a fan is fixedly connected to the output end of the motor via a coupling.

[0006] Preferably, the support mechanism includes a support base and a sliding plate, the energy storage cabinet is snapped into the inside of the sliding plate, the sliding plate is slidably connected to the support base, and the two ends of the sliding plate that contact the support base are arranged with an inclined structure.

[0007] Preferably, the support mechanism further includes ball bearings, and two sets of ball bearings are symmetrically and rotatably installed in the support base, and the ball bearings are in rolling connection with the slide plate.

[0008] Preferably, the support mechanism further includes locking rods, two locking rods are symmetrically fixedly connected to the bottom end of the energy storage cabinet, a rotating rod is rotatably connected to the support base near the locking rods, the rotating rod is engaged with the locking rods, and a rotating block is threaded onto the locking rods.

[0009] Preferably, the part of the rotating rod that contacts the locking rod has an arc-shaped structure, and the rotating block abuts against the side wall of the rotating rod.

[0010] Preferably, the protective mechanism includes a positioning plate and uprights. Two uprights are symmetrically fixedly connected to the support base. The positioning plate is fixedly installed between the two uprights by bolts. The energy storage cabinet is located in the middle of the positioning plate and the uprights.

[0011] Preferably, the protective mechanism further includes a protective plate, which is fixedly connected between the two uprights, and a pad is adhered to the part of the protective plate near the support frame.

[0012] Preferably, the end of the protective plate away from the support frame is arranged with an inclined structure, and the top of the protective plate is provided with a number of grooves at equal intervals.

[0013] The beneficial effects of this utility model are as follows: The symmetrical distribution of the support frame provides precise installation space for the mounting frame and heat dissipation cover, making use of the empty area around the support frame and avoiding installation position conflicts between the heat dissipation cover, mounting frame and other parts, ensuring that the various structures do not interfere with each other during assembly, improving the overall assembly efficiency of the energy storage cabinet. At the same time, when maintaining the heat dissipation components later, there is no need to adjust the position of the support frame or the overall position of the energy storage cabinet, further ensuring the convenience of installation and fixation. The distribution of the support frame will not block the air inlet and outlet ports of the mounting frame, forming a lateral ventilation gap between the side wall of the energy storage cabinet and the support frame. When the motor drives the fan to run, external cold air can quickly enter the mounting frame through the gap of the support frame, and then be introduced into the interior of the energy storage cabinet through the heat dissipation cover. The internal hot air is discharged in the opposite direction through the heat dissipation cover and mounting frame, and quickly diffuses with the help of the ventilation space formed by the support frame, avoiding the accumulation of hot air on the side wall of the energy storage cabinet, significantly improving heat dissipation efficiency, and ensuring that the internal components of the energy storage cabinet operate at a suitable temperature.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] Please see Figures 1-7 As shown, a heat dissipation structure for a vehicle-mounted mobile energy storage cabinet includes an energy storage cabinet 1 and a support mechanism 3 installed at the bottom of the energy storage cabinet 1. A protective mechanism 2 is fixed on the support mechanism 3, and two support frames 5 are symmetrically fixed on the protective mechanism 2. A heat dissipation mechanism 4 is installed on the part of the energy storage cabinet 1 near the support frames 5. The heat dissipation mechanism 4 includes a heat dissipation cover 401 and a mounting frame 402. The heat dissipation cover 401 is fixed to the side wall of the energy storage cabinet 1 near the support frames 5 by bolts. The ventilation holes on the heat dissipation cover 401 are aligned with the heat dissipation vents inside the energy storage cabinet 1. Bolts are passed through the mounting holes of the heat dissipation cover 401 and the threaded holes on the side wall of the energy storage cabinet 1. Tightening the bolts clockwise can fix the heat dissipation cover 401, which facilitates later disassembly and maintenance, and the sealing of the bolt connection can prevent... External rainwater and dust are prevented from entering the interior through the gap between the heat dissipation cover 401 and the energy storage cabinet 1. The heat dissipation cover 401 is connected to the interior of the energy storage cabinet 1. Two mounting frames 402 are symmetrically fixed on the heat dissipation cover 401. The mounting frames 402 are connected to the interior of the energy storage cabinet 1. A motor 403 is fixed inside the mounting frame 402. The output end of the motor 403 is fixedly connected to a fan 404 through a coupling. When the energy storage cabinet 1 generates heat during operation and the internal temperature reaches a preset threshold, the power supply of the motor 403 inside the mounting frame 402 is started. After the motor 403 is powered on, the output end drives the fan 404 to rotate at high speed through the coupling. The suction force generated by the rotation of the fan 404 causes external cold air to enter the interior of the mounting frame 402 through the gap between the support frames 5.

[0019] As a technical optimization of this utility model, the support mechanism 3 includes a support base 301 and a sliding plate 302. The energy storage cabinet 1 is snapped into the interior of the sliding plate 302. The sliding plate 302 is slidably connected to the support base 301. The two ends of the sliding plate 302 that contact the support base 301 are set with an inclined structure. Two sets of ball bearings 306 are symmetrically rotatably installed inside the support base 301. The rolling connection of the ball bearings 306 replaces the sliding friction between the sliding plate 302 and the support base 301, greatly reducing the resistance when the sliding plate 302 is pushed into the support base 301 or when the position of the energy storage cabinet 1 is subsequently adjusted, making the installation easier. The ball bearings 306 are slidably connected to the sliding plate 302, and the bottom end of the energy storage cabinet 1 is symmetrically fixed. Two locking rods 305 are connected. A rotating rod 303 is rotatably connected to the support base 301 near the locking rod 305. The rotating rod 303 is engaged with the locking rod 305. A rotating block 304 is threaded on the locking rod 305. The part of the rotating rod 303 that contacts the locking rod 305 is set with an arc surface structure. The rotating block 304 abuts against the side wall of the rotating rod 303. The rotating rod 303 is squeezed and fixed by the rotating block 304 and cannot be separated from the locking rod 305 in the opposite direction. Through the progressive compression of the threads, the engagement force between the rotating rod 303 and the locking rod 305 can be maintained continuously, avoiding the rotating rod 303 from loosening due to vehicle bumps. The energy storage cabinet 1 is firmly locked from the bottom to prevent it from shifting back and forth on the slide plate 302.

[0020] As a technical optimization of this utility model, the protective mechanism 2 includes a positioning plate 203 and uprights 204. Two uprights 204 are symmetrically fixedly connected to the support base 301, and two support frames 5 are symmetrically fixed. This not only provides a lateral space reference, but also enhances the overall strength of the uprights 204 through its own rigid structure, preventing the uprights 204 from bending due to external forces. The positioning plate 203 is fixedly installed between the two uprights 204 by bolts. The energy storage cabinet 1 is located in the middle of the positioning plate 203 and the uprights 204. The protective plate 201 is fixedly connected between the two uprights 204. A pad 202 is glued to the part of the protective plate 201 near the support frame 5. The design of the pad 202 glued to the side wall of the protective plate 201 can buffer external collisions in subsequent use and prevent the protective plate 201 from directly contacting the energy storage cabinet 1 and causing scratches. The end of the protective plate 201 away from the support frame 5 is set with an inclined structure, and several grooves are provided at equal intervals on the top of the protective plate 201.

[0021] In use, the present invention is first slowly pushed into the sliding plate 302 to form a sliding connection with the support base 301. At this time, the rotatably mounted ball bearings 306 inside the support base 301 can make close contact with both ends of the sliding plate 302. The rolling connection of the ball bearings 306 replaces the sliding friction between the sliding plate 302 and the support base 301, greatly reducing the resistance when pushing the sliding plate 302 into the support base 301 or adjusting the position of the energy storage cabinet 1, making the installation easier. Lift the energy storage cabinet 1, align it with the engaging groove of the sliding plate 302, and lower it vertically. The sliding plate 302 is adapted to the bottom shape of the energy storage cabinet 1, which can quickly perform preliminary positioning of the energy storage cabinet 1 and prevent the energy storage cabinet 1 from shifting during installation. Rotate the side wall of the support base 301. The rotating rod 303 is positioned so that its curved end faces the locking rod 305 mounted on the bottom side wall of the energy storage cabinet 1. It is slowly rotated until the rotating rod 303 is fully engaged with the locking rod 305. Then, the rotating block 304 is picked up, aligned with the external thread of the locking rod 305, and rotated clockwise until the bottom of the rotating block 304 is firmly against the side wall of the rotating rod 303. The rotation is continued until there is no loosening. At this point, the rotating rod 303 is pressed and fixed by the rotating block 304, preventing it from detaching from the locking rod 305. The progressive compression of the thread maintains the engagement force between the rotating rod 303 and the locking rod 305, preventing the rotating rod 303 from loosening due to vehicle bumps and firmly locking the energy storage cabinet 1 from the bottom. To prevent it from shifting forward and backward on the slide plate 302; two uprights 204 are placed vertically and fixed with welding or bolts to form a rigid connection between the uprights 204 and the support base 301. Align the uprights 204 and push them in laterally to fix the protective plate 201 onto the uprights 204. Cover the side position of the top of the energy storage cabinet 1 with the positioning plate 203, and fix both ends of the positioning plate 203 to the two uprights 204 with bolts, so that the energy storage cabinet is within the enclosed space of the positioning plate 203, uprights 204 and support base 301, forming a 360-degree fixation to adapt to the bumpy environment of the vehicle; the design of the adhesive pad 202 on the side wall of the protective plate 201 can buffer external collisions in subsequent use and prevent the protective plate 201 from being damaged. Direct contact with the energy storage cabinet 1 causes scratches; the two support frames 5 are symmetrically fixed, which not only provides a lateral space reference, but also enhances the overall strength of the upright 204 through its own rigid structure, preventing the upright 204 from bending due to external force; the heat dissipation cover 401 is attached to the side wall of the energy storage cabinet 1 near the support frame 5, and the ventilation holes on the heat dissipation cover 401 are aligned with the heat dissipation vents inside the energy storage cabinet 1. The heat dissipation cover 401 can be fixed by passing the bolts through the mounting holes of the heat dissipation cover 401 and the threaded holes on the side wall of the energy storage cabinet 1 and tightening the bolts clockwise, which facilitates the later disassembly and maintenance. The sealing of the bolt connection can prevent external rainwater and dust from entering the interior through the gap between the heat dissipation cover 401 and the energy storage cabinet 1.The mounting frame 402 and the heat dissipation cover 401 are integrated by welding or bolting. The ventilation channel inside the mounting frame 402 is fully connected to the ventilation holes of the heat dissipation cover 401. The symmetrical alignment design of the mounting frame 402 and the heat dissipation cover 401 ensures that the ventilation paths of the two fans 404 are consistent, avoiding uneven heat dissipation on one side due to installation misalignment. The motor 403 is inside the mounting frame 402 and its housing is fixed with bolts. The shaft of the fan 404 is connected to the output end of the motor 403 through a coupling. The mounting frame 402 faces the opening of the gap in the support frame 5, reserving an unobstructed channel for the subsequent introduction of cold air by the fan 404, avoiding ventilation interference between the fan 404 and the support frame 5. When the energy storage cabinet 1 generates heat during operation and the internal temperature reaches a preset threshold, the power supply of the motor 403 inside the mounting frame 402 is activated. After the motor 403 is powered on, its output end drives the fan 404 to rotate at high speed through the coupling. The rotation of the fan 404 generates heat. Suction forces external cold air into the mounting frame 402 through the gaps between the support frames 5. The cold air then enters the heat dissipation cover 401 through the ventilation channels of the mounting frame 402, and is then guided into the energy storage cabinet 1 through the ventilation holes of the heat dissipation cover 401. There, it comes into contact with the heat-generating components such as batteries and circuit boards inside the energy storage cabinet 1, absorbing heat. The heated air, under the thrust of the continuously rotating fan 404, flows in the opposite direction through the heat dissipation cover 401 and the mounting frame 402, and finally exits through the gaps between the support frames 5, diffusing into the external environment, completing one heat dissipation cycle. The gaps between the support frames 5 provide a directional inlet for the cold air, and the elongated structure of the support frames 5 does not obstruct the airflow path, ensuring that the cold air can quickly and unimpededly enter the mounting frame 402. When the hot air is discharged, the open space around the support frames 5 also prevents the hot air from accumulating on the side walls of the energy storage cabinet 1, further improving the heat dissipation effect and ensuring that the internal components of the energy storage cabinet 1 operate within a safe temperature range.

[0022] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
