Description

Technical Field

[0001] This invention relates to the technical field of battery boxes, and particularly to a modular, plug-in battery box housing. Background Technology

[0002] Modular plug-in battery housings are battery casings that integrate modular design and plug-in structure, and are widely used in energy storage systems, electric vehicles, rail transportation, and other fields. This design not only improves the installation efficiency and maintenance convenience of battery systems, but also enhances the system's flexibility and scalability. The following sections will elaborate on the characteristics, structural design, and applications of modular plug-in battery housings from several aspects.

[0003] Chinese patent CN221327983U discloses a prefabricated energy storage battery rack structure, including a support frame assembly, fixing column assemblies, and limiting mounting brackets. Two sets of support frame assemblies are provided, spaced apart, and positioned within a battery cabinet. Multiple fixing column assemblies are provided, spaced apart along a second direction, and mounted on the support frame assemblies. Any two adjacent fixing column assemblies, together with the two sets of support frame assemblies, form a space for accommodating the battery box. Multiple limiting mounting brackets are provided, each positioned within the space, for limiting and securing the battery box. This design aims to address the problem of poor battery box securing effect of existing battery cabinet mounting brackets.

[0004] However, the aforementioned battery box has some shortcomings in actual use:

[0005] 1. Traditional charging compartments have a fixed capacity and cannot accommodate batteries from different brands and models of electric vehicles. This results in the need for multiple charging devices for different batteries, which is costly and inconvenient to carry. Furthermore, the existing battery boxes have a relatively simple design and poor applicability.

[0006] 2. Secondly, when the battery box is placed externally, especially in summer when the outside temperature is high, the battery will generate a lot of heat during charging. Traditional charging cases lack targeted heat dissipation design, which can easily lead to overheating of the battery. This not only reduces charging efficiency but may also cause safety hazards such as bulging and fire. In addition, most existing battery boxes are one-piece structures that cannot be disassembled or flexibly adjusted.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing battery boxes. Summary of the Invention

[0008] To address the above problems, this invention provides a modular, pluggable battery box housing, employing the following technical solution:

[0009] A modular plug-in battery box housing includes four sets of stationary vertical frames, which are arranged in a rectangular shape, and an installation area is formed between the four sets of vertical frames.

[0010] The horizontal limiting frame is slidably installed on the inner wall of the four sets of vertical frames at equal intervals from top to bottom along the height direction of the vertical frame.

[0011] The vertical limiting frame is slidably installed on the inner wall of the horizontal limiting frame at equal intervals along the length direction of the horizontal limiting frame.

[0012] The horizontal and vertical limiting frames are arranged to form several accommodating chambers for battery insertion and installation.

[0013] There is a first adjusting component between the horizontal limiting frame and the vertical frame, and a second adjusting component between the vertical limiting frame and the horizontal limiting frame.

[0014] Five sets of interlocking sealed cabinets are installed on the outer walls of the four sets of vertical frames. A set of easy-to-open and close sealed cabinet doors are also provided on the outer walls of the four sets of vertical frames. The sealed cabinets and the sealed cabinet doors form a protective layer.

[0015] The transverse limiting frame is also equipped with internal and external heat circulation components and a constant temperature module installed inside the transverse limiting frame to intercept heat and maintain constant temperature.

[0016] Preferably, the lateral limiting frame includes two sets of first lateral sleeve rods and two sets of second lateral sleeve rods, wherein splicing frames are installed at the beginning and end of the two first lateral sleeve rods, and the other two second lateral sleeve rods have insertion interfaces for splicing frames to be inserted.

[0017] A stabilizing block is installed inside the second horizontal sleeve rod and at the position of the two insertion interfaces. The stabilizing block has a movable groove along its length. An elastic snap-fit ​​spring is integrally installed in the movable groove of the stabilizing block. A snap-fit ​​groove for snap-fit ​​spring to snap on is opened on the splicing frame.

[0018] Preferably, a stabilizing post is installed on the side wall of the first transverse sleeve, and the stabilizing post is inserted into the second transverse sleeve. A stabilizing hole is opened on the second transverse sleeve for the stabilizing post to be inserted.

[0019] Preferably, the vertical limiting frame includes two sets of first vertical sleeve rods and two sets of second vertical sleeve rods, and the first and second vertical sleeve rods have the same structure as the first and second horizontal sleeve rods.

[0020] Preferably, the second adjusting component includes a fixed rail installed on the second horizontal sleeve rod, and two sets of symmetrically distributed fixed slide rails installed along the height direction of the vertical limiting frame. The fixed slide rails are sleeved on the fixed rails, and locking screws are screwed onto the fixed rails. The locking screws are slidably disposed on the fixed rails, and strip grooves are provided on the fixed rails for the locking screws to slide.

[0021] A locking spring is slidably fitted on the locking screw, and a locking washer is installed on the locking spring. The locking washer abuts against the fixed track, and the elastic force of the locking spring controls the locking washer to abut against the outer wall of the fixed track.

[0022] Preferably, the first adjusting component includes a connecting frame installed on two vertical frames on the same side, two sets of vertical rods connected between the connecting frames installed on the two vertical frames on the same side, and a loop frame slidably installed on the two vertical rods. The loop frame is connected to the corresponding horizontal limiting frame, and a locking bolt is screwed onto the loop frame.

[0023] Preferably, heat dissipation holes are provided on one side of both the horizontal and vertical limiting frames, and both the horizontal and vertical limiting frames are hollow structures.

[0024] The ventilation holes of the horizontal and vertical limiting frames are connected by movement.

[0025] Preferably, a power supply cabinet is also mounted on the sealed cabinet. The power supply cabinet has several power supply wires extending from the inside to the outside. A power supply plug is installed at the end of the power supply wire away from the power supply cabinet. The power supply plug is located on the mounting bracket. Two sets of plug-in pins are symmetrically installed on the back side of the mounting bracket. The plug-in pins drive the mounting bracket to engage with the heat dissipation holes of two adjacent horizontal limit frames to realize the loading of the power supply plug. The mounting bracket is a telescopic structure.

[0026] Preferably, the heat circulation component includes a heat dissipation frame that is slidably inserted and installed on the second transverse sleeve of the transverse limiting frame. Several cooling fans are installed at equal intervals on the heat dissipation frame. The cooling fans are connected to the power supply cabinet through wires. Heat dissipation holes for outward heat dissipation are opened on the heat dissipation frame.

[0027] Preferably, a constant temperature layer is laid on the inner side of the sealed cabinet and the sealed cabinet door. The constant temperature layer includes a constant temperature sponge in the middle and heat insulation foil attached to both sides. Four sets of conveying frames are installed at the four corners of the constant temperature layer. Conveying pipes are connected to the four sets of conveying frames. The end of the conveying pipe away from the conveying frame abuts against the horizontal limiting frame and the vertical limiting frame.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] I. Existing battery boxes mostly adopt welded or integral molding structures, which are not only inconvenient to transport, but also require replacement of the entire box when partial damage occurs, resulting in high maintenance costs. In contrast, the modular splicing design of this invention shows significant advantages in installation, transportation, and maintenance. It can not only be disassembled and reassembled for easy transportation, but also allows for the replacement of partial components during maintenance, greatly improving the economy and convenience of maintenance.

[0030] Second, the No. 1 and No. 2 adjustment components of the present invention cooperate with each other, and through the coordinated adjustment of "height and width", they form a three-dimensional adjustable accommodating chamber, thereby enabling the installation and storage of batteries of different sizes, which greatly improves the applicability of the device.

[0031] Third, the cooperation between the internal and external heat circulation components and the constant temperature module of the present invention, through the heat dissipation frame and the fan to construct a forced convection heat dissipation channel, enables the heat generated by the battery to be quickly dissipated, avoiding the decrease in charging efficiency and safety hazards caused by high temperature.

[0047] The following combination Figures 1-13 This application will be described in further detail.

[0048] This modular plug-in battery box housing is designed to solve the problems of flexible adaptation, efficient heat dissipation and convenient power supply for electric vehicle batteries of different sizes. Through the modular plug-in structure, the housing space can be dynamically adjusted. Combined with the heat circulation system and adjustable power supply components, it can meet the charging needs of high-frequency and multi-specification batteries.

[0049] Reference Figure 1 As shown, a modular plug-in battery box housing includes four sets of stationary vertical frames 1, which are arranged in a rectangular shape, and an installation area is formed between the four sets of vertical frames 1.

[0050] The vertical frame 1 is the supporting foundation of the entire shell, used to fix the horizontal limiting frame 2 and the vertical limiting frame 3, and to bear the weight of the sealing and protective components.

[0051] Four sets of stationary vertical frames 1 are arranged in a rectangular pattern. Each set of vertical frames 1 is made of high-strength aluminum alloy with a hollow interior to reduce weight. The surface is anodized, providing corrosion resistance and wear resistance (suitable for outdoor environments with heavy rain and dust).

[0052] The horizontal limiting frame 2 is slidably installed on the inner wall of the four sets of vertical frames 1 at equal intervals from top to bottom along the height direction of the vertical frame 1.

[0053] The vertical limiting frame 3 is slidably disposed at equal intervals on the inner wall of the horizontal limiting frame 2 along the length direction of the horizontal limiting frame 2;

[0054] The horizontal and vertical limiting frames 2 and 3 are arranged in a longitudinal and transverse manner to form several accommodating chambers 4 for battery insertion and installation.

[0055] A first adjusting component 5 is provided between the horizontal limiting frame 2 and the vertical frame 1, and a second adjusting component 6 is provided between the vertical limiting frame 3 and the horizontal limiting frame 2.

[0056] The horizontal limiting frame 2 is distributed along the height direction of the vertical frame 1, used to separate the receiving chambers 4 of different heights, and to provide an installation base for the vertical limiting frame 3.

[0057] The vertical limiting frame 3 is distributed along the length of the horizontal limiting frame 2, and intersects with the horizontal limiting frame 2 to form a receiving chamber 4, which is used to separate batteries of different widths.

[0058] The height of the vertical limiting frame 3 matches the width of the horizontal limiting frame 2, allowing it to fit precisely into the gap between the two sets of horizontal limiting frames 2, forming a closed receiving chamber 4. A heat dissipation hole 40 is also provided on the side facing the receiving chamber 4, corresponding to the position of the heat dissipation hole 40 on the horizontal limiting frame 2; when the vertical limiting frame 3 moves, the heat dissipation holes 40 of both can be aligned to connect, forming a complete heat dissipation channel.

[0059] Reference Figure 1 and Figure 2 As shown, five sets of interlocking sealed cabinets 10 are installed on the outer walls of the four sets of vertical frames 1. A set of sealed cabinet doors 11 that are easy to open and close is also provided on the outer walls of the four sets of vertical frames 1. A protective layer is formed between the sealed cabinets 10 and the sealed cabinet doors 11.

[0060] The sealed cabinet 10 consists of 5 sets of snap-fit ​​panels (1 set on the top surface and 4 sets on the sides). The main body is made of cold-rolled steel plate, and the surface is treated with phosphate and then coated with epoxy powder. Two sealed cabinet doors 11 are hinged on the sealed cabinet 10. Magnetic sealing strips are installed on the edge of the door frame of the sealed cabinet doors 11, which cooperate with the iron suction strips on the edge of the sealed cabinet 10.

[0061] Furthermore, the two sealed cabinet doors 11 are equipped with waterproof and dustproof mechanical locks, and the sealed cabinet doors 11 are equipped with a touch screen controlled by a chip. The opening and closing of the waterproof and dustproof mechanical locks on the two sealed cabinet doors 11 are controlled by the touch screen, and the sealed cabinet doors 11 are connected to a monitoring device connected to the touch screen.

[0062] Reference Figure 3 , Figure 4 and Figure 5 As shown, the lateral limiting frame 2 includes two sets of first lateral sleeve rods 20 and two sets of second lateral sleeve rods 21. The first and last ends of the two first lateral sleeve rods 20 are equipped with splicing frames 22, while the other two second lateral sleeve rods 21 have insertion interfaces 23 for splicing frames 22 to be inserted.

[0063] A stabilizing block 24 is installed inside the second horizontal sleeve rod 21 and at the position of the two insertion interfaces 23. The stabilizing block 24 has a movable groove along its length. An elastic snap-fit ​​spring 25 is integrally installed in the movable groove of the stabilizing block 24. A snap-fit ​​groove 26 is opened on the splicing frame 22 for snap-fit ​​spring 25 to snap into.

[0064] The transverse limiting frame 2 adopts a splicing structure. Each set includes two first transverse sleeve rods 20 and two second transverse sleeve rods 21, and the cross-sections of the first transverse sleeve rods 20 and the second transverse sleeve rods 21 are U-shaped structures.

[0065] When the horizontal limiting frame 2 is spliced, the splicing frame 22 on the two second horizontal sleeve rods 21 is inserted into the two insertion interfaces 23 at the beginning and end of the first horizontal sleeve rod 20, and the splicing frame 22 abuts against the stabilizing block 24. At this time, the snap-fit ​​spring pieces 25 on both sides of the stabilizing block 24 will be deformed by compression and abut against the snap-fit ​​groove 26 of the splicing frame 22.

[0066] Align the splicing frame 22 with the insertion interface 23, ensuring that the stabilizing column 27 is coaxial with the stabilizing hole. Apply axial force to push the sleeve rod, and the splicing frame 22 is inserted into the insertion interface 23. The snap-fit ​​spring 25 is deformed by compression. When the splicing frame 22 is inserted into the stabilizing block 24, the snap-fit ​​spring 25 springs into the snap-fit ​​groove 26, producing a "click" feedback sound, and the initial fixation is completed.

[0067] Reference Figure 5 and Figure 6 As shown, a stabilizing post 27 is installed on the side wall of the first transverse sleeve 20. The stabilizing post 27 is inserted into the second transverse sleeve 21. A stabilizing hole is opened on the second transverse sleeve 21 for the stabilizing post 27 to be inserted.

[0068] When the first transverse sleeve 20 and the second transverse sleeve 21 are assembled, the stabilizing post 27 installed on the first transverse sleeve 20 will be inserted into the stabilizing hole on the second transverse sleeve 21, further improving the stability between the first transverse sleeve 20 and the second transverse sleeve 21. This ultimately achieves the assembly of the transverse limiting frame 2.

[0069] Reference Figure 7 As shown, the vertical limiting frame 3 includes two sets of first vertical sleeve rods 30 and two sets of second vertical sleeve rods 31. The first vertical sleeve rod 30 and the second vertical sleeve rod 31 have the same structure as the first horizontal sleeve rod 20 and the second horizontal sleeve rod 21.

[0070] The structure of the vertical limiting frame 3 is similar to that of the horizontal limiting frame 2, including two first vertical sleeve rods 30 and two second vertical sleeve rods 31. The installation method of the first vertical sleeve rod 30 and the second vertical sleeve rod 31 of the vertical limiting frame 3 is the same as the installation method of the first horizontal sleeve rod 20 and the second horizontal sleeve rod 21. The only difference between the two is that the horizontal limiting frame 2 is horizontally distributed, while the vertical limiting frame 3 is vertically distributed.

[0071] Furthermore, the horizontal limiting frame 2 and the vertical limiting frame 3 form a crisscrossing grid structure. Both the vertical limiting frame 3 and the horizontal limiting frame 2 can be quickly disassembled and installed.

[0072] Reference Figure 8 and Figure 9 As shown, specifically, the second adjusting component 6 includes a fixed rail 60 installed on the second horizontal sleeve rod 21, and two sets of symmetrically distributed fixed slide rails 61 installed on the vertical limiting frame 3 along the height direction. The fixed slide rails 61 are sleeved on the fixed rails 60, and locking screws 62 are screwed onto the fixed rails 60. The locking screws 62 are slidably disposed on the fixed rails 60, and the fixed rails 60 have strip-shaped grooves 63 for the locking screws 62 to slide.

[0073] A locking spring 64 is slidably sleeved on the locking screw 62, and a locking washer 65 is installed on the locking spring 64. The locking washer 65 abuts against the fixed track 60, and the elastic force of the locking spring 64 controls the locking washer 65 to abut against the outer wall of the fixed track 60.

[0074] The fixed track 60 is installed on the second horizontal sleeve rod 21 of the two horizontal limit frames 2 at the top and bottom of the entire device, and the fixed track 60 is provided with a strip groove 63.

[0075] Several sets of vertical limiting frames 3 are equipped with fixed slide rails 61 at both ends, and the fixed slide rails 61 abut against the fixed track 60. Locking screws 62 are screwed onto the fixed slide rails 61 and pass through the strip grooves 63 of the fixed track 60 to ensure the stability of the vertical limiting frames 3 and enable them to move along the strip grooves 63 of the fixed track 60.

[0076] The locking screw 62 is screwed onto the fixed slide rail 61. The longer the locking screw 62 is exposed to the outside, the smaller the squeezing force of the locking spring 64 and the locking washer 65 on the fixed track 60. At this time, the force required to push the vertical limit frame 3 to move is smaller, and the vertical limit frame 3 moves more easily. Conversely, the shorter the distance of the locking screw 62 exposed to the outside, the greater the squeezing force of the locking spring 64 and the locking washer 65 on the fixed track 60. At this time, the force required to push the vertical limit frame 3 to move is greater, and the vertical limit frame 3 moves more difficult.

[0077] The vertical limiting frame 3 can slide along the fixed track 60; after adjusting to the target position, tighten the locking screw 62, the spring is compressed, and the locking washer 65 is pushed to tightly abut against the fixed track 60, and the vertical limiting frame 3 is fixed by friction; the distance between two adjacent sets of vertical limiting frames 3 can be adjusted arbitrarily to adapt to batteries of different widths.

[0078] Reference Figure 10 As shown, the first adjusting component 5 includes a connecting frame 50 installed on two vertical frames 1 on the same side. Two sets of vertical rods 51 are connected between the connecting frames 50 installed on the two vertical frames 1 on the same side. A loop frame 52 is slidably installed on the two vertical rods 51. The loop frame 52 is connected to the corresponding horizontal limiting frame 2. A locking bolt 53 is also screwed onto the loop frame 52.

[0079] The connecting frame 50 is snapped onto two vertical frames 1 on the same side to limit and fix the vertical frames 1. The connecting frame 50 is also provided with a vertical rod 51, and several horizontal limiting frames 2 are slidably set on the vertical rod 51 through the loop frame 52.

[0080] Loosen the locking bolts 53 on the loop frame 52, and the loop frame 52 can slide up and down along the vertical rod 51, driving the horizontal limit frame 2 to move synchronously; after adjusting to the target height, tighten the locking bolts 53 so that it abuts against the vertical rod 51 to achieve fixation.

[0081] The spacing between two adjacent sets of horizontal limiting frames 2 can be adjusted within a certain range to accommodate batteries of different thicknesses.

[0082] Reference Figure 11 , Figure 12 and Figure 13 As shown, a power supply cabinet 90 is also mounted on the sealed cabinet 10. Several power supply wires extend from the inside to the outside of the power supply cabinet 90. A power supply plug 91 is installed at the end of the power supply wire away from the power supply cabinet 90. The power supply plug 91 is located on the mounting bracket 92. Two sets of plug-in pins are symmetrically installed on the back side of the mounting bracket 92. The plug-in pins drive the mounting bracket 92 to engage with the heat dissipation holes 40 of the two adjacent transverse limiting frames 2 to realize the loading of the power supply plug 91. The mounting bracket 92 is a telescopic structure.

[0083] The power supply cabinet 90 is a known existing structure, which contains a charger module and a control board. The charger module is used to charge each battery.

[0084] The control board features voltage regulation, current limiting, overcharge protection, and short-circuit protection. It represents a known existing structure.

[0085] The power plug 91 is compatible with common electric vehicle battery interfaces (triangular plug, round plug, T-type plug) and allows for quick replacement of the plug head (connected via a snap-fit).

[0086] It uses flame-retardant ABS material for the plug shell and H62 brass for the pins. It also features a structure to prevent misinsertion and an electric shock protection door.

[0087] In practice, the power plug 91, mounting bracket 92, and connector are movable structures, and the power supply wires connected to their back sides can be pulled and stretched. It should be noted that the connector is not marked in the diagram.

[0088] When the battery is inserted into the receiving chamber 4 between the horizontal limiting frame 2 and the vertical limiting frame 3, the charging port of the battery is located on the side wall or handle, not at the tail of the battery. At this time, the power plug 91, the mounting bracket 92 and the plug post can be pulled out, and the power plug 91 can be directly inserted into the charging port of the battery. Then, the power plug 91 and the battery are inserted into the receiving chamber 4 to charge the battery.

[0089] Furthermore, the horizontal limiting frame 2 and the vertical limiting frame 3 can be adjusted in position. Therefore, when the size of the battery to be charged is different, the horizontal limiting frame 2 and the vertical limiting frame 3 can be adjusted in advance to the size structure that is more common in the market. Since batteries are updated very quickly, when the existing size cannot meet the new battery size, technicians can actively adjust the position of the horizontal limiting frame 2 and the vertical limiting frame 3 when maintaining the equipment, thereby adjusting the receiving chamber 4 that accommodates the battery.

[0090] This greatly improves the applicability and flexibility of the device.

[0091] Modular adjustment allows it to adapt to electric vehicle batteries of different specifications and sizes, solving the problem of "one compartment for one use" in traditional charging compartments, reducing the cost of using the equipment, and improving their charging convenience.

[0092] The modular design shortens assembly time, and the adjustable power plug 91 allows for temporary battery charging without additional tools, improving work efficiency.

[0093] Reference Figure 13 As shown, specifically, heat dissipation holes 40 are provided on one side of both the horizontal limiting frame 2 and the vertical limiting frame 3, and both the horizontal limiting frame 2 and the vertical limiting frame 3 are hollow structures.

[0094] The heat dissipation holes 40 of the horizontal limiting frame 2 and the vertical limiting frame 3 are connected by movement.

[0095] The heat circulation component 7 includes a heat dissipation frame 70 that is slidably inserted and installed on the second horizontal sleeve 21 of the horizontal limiting frame 2. Several cooling fans 71 are installed at equal intervals on the heat dissipation frame 70. The cooling fans 71 are connected to the power supply cabinet 90 through wires. Heat dissipation holes 40 are opened on the heat dissipation frame 70 to dissipate heat outward.

[0096] The interior of the horizontal and vertical limiting frame 3 is a through hollow channel, and four spiral guide ribs are set on the inner wall of the channel to guide the orderly flow of air; the heat dissipation hole 40 faces the side wall of the receiving chamber 4 to ensure that the heat of the battery can be directly carried away when the gas flows.

[0097] A graphene thermally conductive coating is sprayed onto the inner surface of the hollow structure of the limiting frame to accelerate heat transfer.

[0098] It should be noted that a removable nylon dust filter is installed on the outside of the heat dissipation frame 70, which is fixed by clips and can be cleaned and replaced regularly.

[0099] The heat generated during battery charging is transferred to the air in the chamber through convection. The hot air enters the hollow channel of the limiting frame through the heat dissipation hole 40 and flows to the heat dissipation frame 70 under the guidance of the spiral guide rib.

[0100] In practice, the heat dissipation frame 70 can be pulled out or installed in the slot of the transverse limiting frame 2, which facilitates the maintenance of the heat dissipation frame 70. When the battery is charging, the cooling fan 71 inside the heat dissipation frame 70 rotates. After the cooling fan 71 rotates, it begins to absorb heat on one side, which drives the heat to exchange with the outside air, thereby effectively controlling the temperature inside the entire structure and keeping it constant in a suitable environment.

[0101] Let's look again. Figure 11 and Figure 12 As shown, specifically, a constant temperature layer 80 is laid on the inner side of the sealed cabinet 10 and the sealed cabinet door 11. The constant temperature layer 80 includes a constant temperature sponge 82 set in the middle and heat insulation foil 81 attached to both sides. Four sets of conveying frames 83 are installed at the four corners of the constant temperature layer 80. Conveying pipes are connected to the four sets of conveying frames 83. The end of the conveying pipe away from the conveying frame 83 abuts against the heat dissipation holes 40 of the horizontal limiting frame 2 and the vertical limiting frame 3.

[0102] It should be noted that the temperature-regulating sponge 82 is composed of high-density polyurethane sponge. When its interior is filled with hot air, it can form a temperature-regulating layer. With the assistance of the heat-insulating foil 81 on both sides, it prevents rapid heat loss. When it is winter and the outside air is cold, the heat-insulating foil 81, together with the middle temperature-regulating layer 80, can effectively isolate the cavity where the battery is installed from the outside, preventing the internal battery temperature from being too low, which would lead to a decrease in battery charging performance.

[0103] Similarly, when the outside air is hot, the inside of the thermostatic sponge 82 is filled with cooler airflow. The heat-insulating tin foil 81, together with the middle thermostatic layer 80, can effectively isolate the cavity where the battery is installed from the outside, preventing the internal battery temperature from getting too high and causing the battery charging performance to decline.

[0104] The gas filling of the constant temperature sponge 82 is mainly provided through the conveying frame 83 and the conveying pipe. The conveying pipe absorbs the gas flowing in the horizontal limiting frame 2 and the vertical limiting frame 3, and conveys it to the constant temperature sponge 82 through the conveying frame 83.

[0105] During work:

[0106] Step 1: Adjust the bracket position. First, select the corresponding heat dissipation hole 40 on the horizontal limit frame 2 according to the battery width to determine the horizontal position. Move the horizontal limit frame 2 to the specified position. According to the battery interface depth, stretch and control the vertical limit frame 3 to determine the longitudinal length. At this time, adjust the longitudinal and transverse arrangement positions of the horizontal limit frame 2 and the vertical limit frame 3.

[0107] Step 2: Fix the power supply cabinet 90 to the side of the sealed cabinet 10 with bolts, connect the mains power, turn on the switch and check if the indicator light is normal, connect one end of the power supply wire to the output interface of the power supply cabinet 90 and tighten it, connect the other end to the power supply plug 91, select the corresponding plug according to the battery interface type, and check the equipment operation.

[0108] Insert the power plug 91 into the slot of the mounting bracket 92 and secure it to ensure that the plug is installed firmly.

[0109] Step 3: Connect the battery, open the cabinet door, put the battery into the chamber, and insert the power plug 91 into the battery interface (you will hear a "click" sound when it is in place).

[0110] Step 4: Start charging, close and lock the cabinet door, adjust the voltage setting on the power supply cabinet 90, and press the switch to start charging.

[0111] Step 5: After the battery is fully charged, the power supply cabinet 90 will automatically disconnect the power to the corresponding power plug 91, then open the cabinet door, unplug the plug, and take out the battery.

[0112] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
