Description

Technical Field

[0001] This invention relates to the technical field of energy storage emergency charging boxes for new energy vehicles, specifically an energy storage emergency charging box for new energy vehicles. Background Technology

[0002] Although the driving range of new energy vehicles has increased from 100-200km in the early days to the mainstream 400-600km, users' range anxiety has not been completely eliminated. Traditional energy replenishment solutions, including fixed charging piles and battery swapping stations, all rely on grid access or fixed sites, and cannot achieve mobile and scenario-based emergency energy replenishment. This demand gap has directly driven the technological research and development of energy storage emergency charging boxes.

[0003] A new energy vehicle energy storage emergency charging box with patent publication number CN120327259A includes an outer shell, an end cover, and battery cells. When the end cover is connected to the outer shell, the abutment at the bottom of the end cover can press down on the pad and the fixing compartment. At the same time, the transmission rack on the abutment drives the corresponding transmission gear, causing the transmission screw to rotate and drive the corresponding first and second sliding plates to move towards each other. This allows the first and second sliding plates to clamp the middle of the outer side of the corresponding battery cell. Meanwhile, the pressure bar on the abutment can abut against the corresponding wedge. The wedge presses the corresponding pressure block and flips it over, thereby forming a contact positioning of the end of the corresponding battery cell. In this way, when the end cover and the outer shell are assembled and positioned, the ends and outer sides of multiple sets of battery cells inside can be positioned simultaneously, thus realizing quick and convenient disassembly and assembly between multiple sets of battery cells.

[0004] However, the aforementioned energy storage emergency charging box for new energy vehicles does not have a buffer device for the battery cells. When installing the battery cells, the battery cells will come into contact with the bottom surface of the outer casing. When the workers are installing the battery cells, it is difficult to ensure that the battery cells are placed inside gently. As a result, the battery cells are prone to impact with the outer casing during installation, which can cause damage to the battery cells. Summary of the Invention

[0009] According to the above technical solution, the stabilizing device includes an L-shaped plate, a fixed spring, a pressure plate, a pressing block, and a stop block. The L-shaped plate is fixedly connected to the bottom surface of the end cap, and the fixed spring is fixedly connected to the bottom surface of the L-shaped plate. When the L-shaped plate moves downward, it compresses the fixed spring.

[0010] According to the above technical solution, the pressure plate is fixedly connected to the end of the fixed spring away from the L-shaped plate, the extrusion block is fixedly connected to the upper surface of the pressure plate, the extrusion block penetrates the L-shaped plate and is slidably connected at the penetration point, the stop block is slidably connected to the bottom surface of the end cap, and the pressure plate moves upward to drive the extrusion block to slide.

[0011] According to the above technical solution, the side wall of the outer shell is provided with a heat dissipation device to promote heat dissipation. The heat dissipation device includes a sliding plate, a moving block, a return spring, a push block, a baffle, a top rod, a rain shield, and a sealing plate. The sliding plate is slidably connected to the upper surface of the positioning plate.

[0012] According to the above technical solution, the moving block is fixedly connected to the side wall of the sliding plate near the pressure plate, one end of the return spring is fixedly connected to the side wall of the sliding plate away from the pressure plate, the other end of the return spring is fixedly connected to the inner wall of the outer shell, and the push block is fixedly connected to the side wall of the sliding plate away from the pressure plate.

[0014] This invention provides an energy storage emergency charging box for new energy vehicles. It has the following beneficial effects: 1. This invention incorporates a buffer device. During battery cell installation, it works in conjunction with a limiting strip, positioning plate, fixing plate, buffer spring, and placement plate to support and slow down the battery cells, thereby achieving a buffering effect. This prevents the battery cells from impacting the bottom surface of the inner wall of the outer casing when placed into the positioning plate, thus avoiding damage to the battery cells. It also solves the problem of battery cells easily sliding down rapidly due to gravity and impacting the outer casing when directly installed. Simultaneously, the invention utilizes a long rod, hinge block, fixing block, straightening block, and sliding rod to straighten and position the battery cells, preventing misalignment between the battery cells and the positioning holes on the positioning plate. This avoids misalignment or wobbling of the battery cells at the positioning plate, which could lead to poor contact and solves the problem of battery cells easily wobbling inside the battery box, causing poor contact.

[0015] 2. This invention includes a stabilizing device. When the outer casing is closed, the L-shaped plate, fixing spring, and pressure plate work together to press and fix the battery cells, preventing them from sliding freely inside the casing and causing repeated impacts that could damage them and render them unusable. This solves the problem of the battery cells easily sliding and being impacted inside the casing due to the lack of a fixing mechanism. Furthermore, when fixing the battery cells, the pressure plate is further secured by a squeezing block and a stop block, preventing the pressure plate from being compressed again by the inertia of the sliding battery cells, which could lead to loosening of the connection between the battery cells and the device or poor contact. This solves the problem that the fixing spring still has some compression space, making it difficult to fix the pressure plate securely.

[0016] 3. This invention is equipped with a heat dissipation device. When the end cover is fixed, it works in conjunction with a sliding plate, a moving block, a return spring, a push block, and a top rod to open the baffle, thereby opening the heat dissipation vents on the side wall of the outer casing. This promotes heat dissipation inside the electrical box and prevents damage to internal electrical components caused by poor heat dissipation when the electrical box is completely closed. This solves the problem of poor heat dissipation when the electrical box is closed. When the baffle is opened to expose the heat dissipation vents, a rain shield and a sealing plate are used to shield the connection between the baffle and the outer casing and the gaps. This prevents rainwater and snow from entering the electrical components inside the electrical box during rainy or snowy weather, thus solving the problem of poor sealing at the heat dissipation vents and easy leakage of rain and water.

[0019] 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.

[0020] Please see Figures 1-7One embodiment of the present invention is: an energy storage emergency charging box for new energy vehicles, including an outer shell 1, a socket 2 provided on the surface of the outer shell 1, the socket 2 being electrically connected to electrical components inside the outer shell 1, an end cover 3 penetrating through the upper surface of the outer shell 1 and fitting snugly at the penetration point, a screw penetrating through the end cover 3 and being rotatably connected at the penetration point, the screw penetrating through the upper surface of the outer shell 1 and being threadedly connected at the penetration point, rotating the screw to unscrew and pull it out, opening the end cover 3, and a buffer device for buffering the battery cells is provided inside the outer shell 1.

[0021] The buffer device includes a limiting strip 41, a positioning plate 42, a fixing plate 43, a buffer spring 44, a placement plate 45, a long rod 46, a hinge block 47, a fixing block 48, a straightening block 49, and a sliding rod 410. The limiting strip 41 is fixedly connected to the inner wall of the outer shell 1, and the positioning plate 42 is slidably connected to the inner wall of the outer shell 1. The bottom surface of the positioning plate 42 is in contact with the upper surface of the limiting strip 41. The positioning plate 42 is placed inside the outer shell 1 and slides downward inside the outer shell 1 until it contacts the limiting strip 41. The limiting strip 41 supports the positioning plate 42. The battery cells are inserted one by one into the through holes of the positioning plate 42. The fixing plate 43 is fixedly connected to the bottom of the positioning plate 42. On the surface of the fixed plate 43, a buffer spring 44 is fixedly connected to the upper surface of the fixed plate 43, and a placement plate 45 is fixedly connected to the end of the buffer spring 44 away from the fixed plate 43. When the battery cell moves downward to the placement plate 45, the weight of the battery cell pushes the placement plate 45 downward. When the placement plate 45 moves downward, it compresses the buffer spring 44. The elastic force of the buffer spring 44 counteracts the downward gravity of the battery cell, slowing down the downward movement of the battery cell and buffering the downward placement surface of the battery cell. This prevents the downward acceleration of the battery cell due to gravity from increasing and causing it to collide with the outer casing 1. A long rod 46 is fixedly connected to a protrusion on the side wall of the placement plate 45. On the upper surface, when the placement plate 45 moves downward under the weight of the battery cells, it causes the long rod 46 to slide downward as well. The long rod 46 passes through the positioning plate 42 and is slidably connected at the point of penetration. The hinge block 47 is hinged to the end of the long rod 46 away from the placement plate 45. When the long rod 46 slides downward, it causes the hinge block 47 to rotate. The fixing block 48 is fixedly connected to the upper surface of the positioning plate 42. The straightening block 49 is hinged to the end of the hinge block 47 away from the long rod 46. The sliding rod 410 is fixedly connected to the side wall of the straightening block 49. The sliding rod 410 passes through the fixing block 48 and is slidably connected at the point of penetration. When the hinge block 47 rotates, it pulls the straightening block 49 to slide towards the battery cells. Two sets of... The straightening blocks 49 slide towards the battery cell, moving closer to each other to position and straighten the battery cell on both sides. After the battery cell is placed, the end cap 3 is placed on top and fixed with screws. When installing the battery cell, this buffer device, together with the limit strip 41, positioning plate 42, fixing plate 43, buffer spring 44 and placement plate 45, supports and slows down the battery cell, thereby achieving the effect of buffering the battery cell and preventing the battery cell from impacting the bottom surface of the inner wall of the outer shell 1 when it is placed into the positioning plate 42, which would cause damage to the battery cell. This solves the problem that the battery cell is prone to sliding down quickly due to gravity and impacting the outer shell 1 when it is directly installed. While buffering the battery cells, the long rod 46, hinge block 47, fixing block 48, straightening block 49 and sliding rod 410 are used to straighten and position the battery cells, so as to avoid the battery cells from not fitting the positioning holes of the positioning plate 42, which would cause the battery cells to be tilted or shake at the positioning plate 42, resulting in poor contact of the battery cells. This solves the problem that the battery cells are easy to shake inside the battery box and cause poor contact.

[0022] In this embodiment, during operation: The screw is rotated, unscrewed, and pulled out. The end cover 3 is opened, and the end cover 3 and its internal stabilizing device are removed. The positioning plate 42 is placed inside the outer shell 1, allowing it to slide downwards until it contacts the limiting strip 41. The limiting strip 41 supports the positioning plate 42. Battery cells are inserted one by one into the through holes of the positioning plate 42. When the battery cells move downwards to the placement plate 45, their weight pushes the placement plate 45 downwards. As the placement plate 45 moves downwards, it compresses the buffer spring 44. The restoring elasticity of the buffer spring 44 counteracts the downward force of gravity on the battery cells, slowing their downward movement and buffering the downward placement surface of the battery cells. This prevents the battery cells from accelerating downwards due to gravity and colliding with the outer shell 1. When the placement plate 45 is subjected to… When the battery cell moves downwards due to gravity, it causes the long rod 46 to slide downwards as well. When the long rod 46 slides downwards, the hinge point between the long rod 46 and the hinge block 47 also moves downwards. The end of the hinge block 47 away from the long rod 46 is hinged to the straightening block 49. The straightening block 49 is restricted by the sliding rod 410 and can only slide on the side wall of the fixed block 48. Therefore, the position of the hinge point between the hinge block 47 and the straightening block 49 remains unchanged in the vertical direction. When the hinge point between the long rod 46 and the hinge block 47 moves downwards, the hinge block 47 itself also rotates. The rotation of the hinge block 47 pulls the straightening block 49 to slide towards the battery cell. Both sets of straightening blocks 49 slide towards the battery cell and move closer to each other, positioning and straightening the battery cell on both sides. After the battery cell is placed, the end cap 3 is put on and fixed with screws.

[0023] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the interior of the outer shell 1 is provided with a stabilizing device for easy fixing. The stabilizing device includes an L-shaped plate 51, a fixing spring 52, a pressure plate 53, a pressing block 54, and a stop block 55. The L-shaped plate 51 is fixedly connected to the bottom surface of the end cap 3. A magnet is fixed inside the L-shaped plate 51. The end cap 3 drives the L-shaped plate 51 to move downward. The fixing spring 52 is fixedly connected to the bottom surface of the L-shaped plate 51. When the L-shaped plate 51 moves downward, it drives the fixing spring 52 to move downward. The pressure plate 53 is fixedly connected to the end of the fixing spring 52 away from the L-shaped plate 51. The fixing spring 52 carries... The moving pressure plate 53 also moves downwards. When the pressure plate 53 contacts the battery cell, it stops moving downwards, while the end cap 3 continues to move downwards. The fixing spring 52 is compressed by the interaction force between the pressure plate 53 and the end cap 3. The restoring force of the fixing spring 52 applies a downward pushing force to the pressure plate 53, making the bottom surface of the pressure plate 53 fit tightly against the upper surface of the battery cell and applying downward pressure to fix the battery cell. The pressing block 54 is fixedly connected to the upper surface of the pressure plate 53. The pressing block 54 passes through the L-shaped plate 51 and is slidably connected at the penetration point. When the pressure plate 53 contacts the battery cell and stops, the end cap 3 continues to move downwards. During movement, the pressure plate 53 moves upward relative to the end cover 3. As the pressure plate 53 moves upward, it pushes the pressing block 54 to slide upward as well. The stop block 55 is slidably connected to the bottom surface of the end cover 3. The stop block 55 is made of iron. When the end cover 3 is removed, the stop block 55 is reset by the attraction of the magnet inside the L-shaped plate 51. When the pressing block 54 slides upward to the stop block 55, the pressing block 54 pushes the stop block 55 to slide away from the L-shaped plate 51. The stop block 55 slides until its upper surface is in contact with the upper surface of the inner wall of the outer shell 1. When the stop block 55 is in contact with the upper surface of the inner wall of the outer shell 1, the pressing block 54 is tightly connected to the stop block 55. The tight fit is also relatively fixed. The pressing block 54, together with the stop block 55, fixes the pressure plate 53 to prevent the pressure plate 53 from shaking inside the outer shell 1, causing the battery cells to repeatedly collide with the pressure plate 53. When the outer shell 1 is closed, this stabilizing device, together with the L-shaped plate 51, the fixing spring 52 and the pressure plate 53, presses and fixes the battery cells to prevent the battery cells from sliding up and down unrestricted inside the battery box, which would cause the battery cells to repeatedly collide and be damaged inside the battery box, making the battery cells unusable. This solves the problem that there is no fixing mechanism inside the battery box, and the battery cells are easy to slide and be impacted repeatedly inside. When fixing the battery cells, the pressing block 54 and the stop block 55 are used to further fix the pressure plate 53, thereby preventing the pressure plate 53 from being affected by the inertia of the battery cells sliding and compressing the fixing spring 52 again, which would cause the connection between the battery cells and the equipment to become loose or have poor contact. This solves the problem that the fixing spring 52 still has a certain amount of compression space and is difficult to fix the pressure plate 53.

[0024] The outer casing 1 has a heat dissipation device on its side wall to promote heat dissipation. The heat dissipation device includes a sliding plate 61, a moving block 62, a return spring 63, a push block 64, a baffle 65, a push rod 66, a rain shield 67, and a sealing plate 68. The sliding plate 61 is slidably connected to the upper surface of the positioning plate 42. The moving block 62 is fixedly connected to the side wall of the sliding plate 61 near the pressure plate 53. When the pressure plate 53 moves to the moving block 62, the pressure plate 53 pushes the moving block 62 to move away from the pressure plate 53. The movement of the moving block 62 causes the sliding plate 61 to slide. One end of the return spring 63 is fixedly connected to the side wall of the sliding plate 61 away from the pressure plate 53. The other end of the return spring 63 is fixedly connected to the inner wall of the outer casing 1. The sliding plate 61 slides to compress the return spring 63. When the end cover 3 is removed and the battery is taken out, the moving block 62 is no longer pushed by the pressure plate 53. At the same time, the sliding plate 61 is reset by the restoring force of the return spring 63, which drives the moving block 62 to reset as well. The push block 64 is fixedly connected to the side wall of the sliding plate 61 away from the pressure plate 53. The sliding plate 61 slides to drive the push block 64 to move away from the pressure plate 53. The side wall of the outer casing 1 is provided with a heat dissipation vent. The baffle 65 is hinged to the upper surface of the heat dissipation vent. The push rod 66 is fixedly connected to the baffle 64. 5. Near the side wall of push block 64, when push block 64 moves to push rod 66, push rod 66 to rotate around the hinge point between baffle 65 and outer casing 1. The rotation of push rod 66 causes baffle 65 to rotate and open, opening the heat dissipation vents on the side wall of outer casing 1 to promote internal heat dissipation. Rain shield 67 is fixedly connected to both sides of baffle 65. When baffle 65 rotates, it also drives rain shield 67 to rotate. When baffle 65 is open, rain shield 67 blocks rain from entering the electrical box from the heat dissipation vents during use in rainy or snowy weather. Sealing plate 68 is slidably connected to the outer wall of outer casing 1. When baffle 65 rotates... When opened, the side wall of the baffle 65 slides against the side of the sealing plate 68, and the baffle 65 pushes the sealing plate 68 to slide upward. The sealing plate 68 fits tightly against the outer shell 1, blocking the hinge between the baffle 65 and the outer shell 1. When the end cover 3 is fixed, the heat dissipation device, together with the sliding plate 61, the moving block 62, the return spring 63, the push block 64, and the top rod 66, pushes the baffle 65 to open, opening the heat dissipation vents on the side wall of the outer shell 1, thereby promoting the heat dissipation effect inside the electrical box and preventing the electrical box from being difficult to dissipate heat after being completely closed, which could lead to damage to the internal electrical components. This solves the problem of difficult heat dissipation after the electrical box is closed. When the baffle 65 is opened to expose the heat dissipation vent, the rain shield 67 and the sealing plate 68 work together to shield the connection and gap between the baffle 65 and the outer casing 1, thereby preventing rain and snow water from entering through the connection and gap between the baffle 65 and the outer casing 1 during rainy or snowy weather, which could damage the electrical components inside the electrical box. This solves the problem of poor sealing at the heat dissipation vent, which easily leads to rain and water leakage.

[0025] In this embodiment, during operation: when the end cap 3 closes downwards from above the outer casing 1, the end cap 3 drives the L-shaped plate 51 downwards. As the L-shaped plate 51 moves downwards, it also drives the fixing spring 52 downwards. The fixing spring 52 drives the pressure plate 53 downwards as well. When the pressure plate 53 contacts the battery cell, it stops moving downwards, while the end cap 3 continues to move downwards. The fixing spring 52 is compressed by the interaction force between the pressure plate 53 and the end cap 3. The restoring elastic force of the fixing spring 52 applies a downward pushing force to the pressure plate 53, causing the bottom surface of the pressure plate 53 to fit tightly against the upper surface of the battery cell, applying downward pressure to the battery cell and fixing it in place. When the pressure plate 53 contacts the battery cell and stops, the end cap 3 continues to move downwards. When the pressure plate 53 moves upward relative to the end cover 3, the pressure plate 53 pushes the pressing block 54 to slide upward as well. When the pressing block 54 slides upward to the stop block 55, the inclined surface of the pressing block 54 slides against the side of the stop block 55. The pressing block 54 pushes the stop block 55 to slide away from the L-shaped plate 51. The stop block 55 slides until its upper surface is in contact with the upper surface of the inner wall of the outer casing 1. When the stop block 55 is in contact with the upper surface of the inner wall of the outer casing 1, the pressing block 54 is also relatively fixed due to the tight cooperation with the stop block 55. The pressing block 54 and the stop block 55 fix the pressure plate 53 to prevent the pressure plate 53 from shaking inside the outer casing 1, which would cause the battery cells to repeatedly collide with the pressure plate 53.

[0026] The pressure plate 53 moves upward relative to the end cover 3. When the pressure plate 53 moves to the moving block 62, the side of the pressure plate 53 slides against the inclined surface of the moving block 62. The pressure plate 53 pushes the moving block 62 to move away from the pressure plate 53. The movement of the moving block 62 causes the sliding plate 61 to slide and compresses the reset spring 63. When the end cover 3 is removed and the battery cell is taken out, the moving block 62 is no longer pushed by the pressure plate 53. At the same time, the sliding plate 61 is reset by the restoring force of the reset spring 63, which also causes the moving block 62 to reset. The sliding plate 61 slides and causes the push block 64 to move away from the pressure plate 53. When the push block 64 moves to the top rod 66, the inclined surface of the push block 64 slides against the outer wall of the top rod 66. The top rod 66 is fixed to the side wall of the baffle 65. Hinged to the side wall of the outer casing 1, it can only rotate around the hinge point between the baffle 65 and the outer casing 1. Therefore, when the push block 64 moves to the push rod 66, it pushes the push rod 66 to rotate around the hinge point between the baffle 65 and the outer casing 1. The rotation of the push rod 66 causes the baffle 65 to rotate and open, opening the heat dissipation vent on the side wall of the outer casing 1 and promoting internal heat dissipation. When the baffle 65 rotates, it also drives the rain shield 67 to rotate. When the baffle 65 is open, the rain shield 67 blocks the side wall of the baffle 65 to prevent rain and snow from entering the electrical box from the heat dissipation vent during use in rainy or snowy weather. When the baffle 65 rotates and opens, the side wall of the baffle 65 slides against the side of the sealing plate 68. The baffle 65 pushes the sealing plate 68 to slide upward, and the sealing plate 68 fits tightly against the outer casing 1, blocking the hinge point between the baffle 65 and the outer casing 1.
