Description

Technical Field

[0001] The utility model relates to the technical field of battery compartments, in particular to a battery compartment module and a battery swapping cabinet with the battery compartment module. Background Art

[0002] With the development of sharing technology, intelligent battery swapping cabinets have emerged in various cities. Nowadays, the main means of transportation for food deliverymen and couriers are two-wheeled or three-wheeled electric vehicles. Leasing lithium batteries for use in electric vehicles is the mainstream solution for current food deliverymen and couriers. The intelligent battery swapping cabinet mainly includes a cabinet body and a battery compartment module arranged in the cabinet body. The battery compartment module includes a battery compartment for charging the battery. The user can charge the battery by putting the battery into the battery compartment so that the battery contacts the charging socket.

[0003] For a battery swapping cabinet with a battery compartment module, since the battery generates a relatively large amount of heat during charging in the battery compartment, in order to prevent the battery from exploding and causing a fire during the charging process, it is usually necessary to set a sprinkler head in the battery compartment for spraying water when the temperature in the battery compartment is abnormal.

[0004] Taking the intelligent battery swapping cabinet as an example, in the prior art, the sprinkler head is usually supplied with water by a water supply pipe arranged on the back of the battery swapping cabinet. See Figure 1 , Figure 1 which is a battery swapping cabinet provided by the prior art, where 1 represents the cabinet body, 2 represents the battery compartment module, 3 represents the water supply device (31 represents the water storage tank, 32 represents the water delivery pipe), and 4 represents the drainage device (41 represents the water guide groove, 42 represents the drainage pipe). Figure 1 In , the water in the water delivery pipe 32 is drained into the sprinkler heads arranged at the top of each battery compartment through each capillary tube connected thereto. Obviously, this water supply structure results in many pipes in the battery swapping cabinet, a complex structure, and a cramped internal space. In addition, due to many capillary tubes for drainage, in order to ensure normal water supply to each battery compartment, multiple water pumps will be set to ensure the water supply pressure, which further increases the cost of the battery swapping cabinet. Utility Model Content

[0005] In view of this, the purpose of the present utility model is to overcome the deficiencies of the prior art and provide a battery compartment module and a battery swapping cabinet with the battery compartment module to solve the problems of complex structure and high cost of the fire-fighting water supply pipe in the battery compartment in the prior art.

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will describe the technical solutions of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0036] The following will further describe the technical solutions of the present invention in detail through the accompanying drawings and embodiments.

[0037] Embodiment 1

[0038] Refer to Figures 2A - 2D and Figure 3 A battery compartment module 100 provided for an embodiment of the present invention includes a battery compartment and a compartment cover 21. The battery compartment is a cavity with one open side surrounded by a left side plate 11, a right side plate 12, a top plate 14, a bottom plate 13, and a back plate 16. The compartment cover 21 is disposed at the opening of the cavity;

[0039] A spray pipe 24 is provided at the opening. One end of the spray pipe 24 penetrates and inserts into the upper end of the left side plate 11, and the other end penetrates and inserts into the upper end of the right side plate 12. The top plate 14 abuts between the spray pipe 24 and the back plate 16;

[0040] A spray head 25 is provided on the spray pipe, and the water spray port of the spray head 25 faces the inside of the cavity. A drain hole B is provided at the connection between the back plate 16 and the bottom plate 13.

[0041] It should be noted that:

[0042] 1. The length of the top plate is less than the lengths of the left side plate and the right side plate. Since the left side plate and the right side plate are arranged oppositely, and the length of the top plate is less than the lengths of the left side plate and the right side plate, after the top plate is installed, the top plate will be shorter than the left side plate and the right side plate, forming a notch; installing the spray pipe at the notch can prevent the spray pipe from blocking the opening of the cavity, so that it does not affect the normal entry and exit of the battery into the battery compartment.

[0043] 2. When the battery compartment module is installed, it is inclinedly arranged in the battery swapping cabinet in a form with the inside lower and the outside higher at a preset inclination angle; at the connection between the back plate and the bottom plate of each battery compartment, a drainage port is provided; each battery compartment module is equipped with a drainage groove, which is arranged on the back of each layer of battery compartments and is attached to the water outlet direction of the drainage port.

[0044] It can be understood that the technical solution provided in this embodiment, by setting a spray pipe at the opening of the battery compartment cavity and directly connecting the spray pipe to the water source, can realize that the fire fighting waterway directly enters the battery compartment from the front of the battery compartment to extinguish the fire. Compared with the prior art where a spray head is provided at the top of the battery compartment and water is supplied by capillary drainage from the main water supply pipe at the back of the battery compartment, the intricate capillary tubes are eliminated, greatly simplifying the structure and waterway design of the battery compartment.

[0045] When multiple battery compartment modules are connected in series, the battery compartment modules on the same layer can share the same spray pipe. After the spray pipe is filled with water, it can supply water to each battery compartment on the same layer. Compared with the prior art where multiple capillary tubes are used to drain water from the back of the battery swapping cabinet to supply water to the spray head, the technical solution provided in this embodiment greatly simplifies the fire fighting water supply line of the battery compartment and saves product costs.

[0046] In specific practice, referring to Figures 2A - 2D and Figure 3 , the cabin cover 21 is a rolling shutter door 21, and a motor 17 with a speed reducer is provided on the back plate 16;

[0047] A sliding seat 22 is provided on the top plate 14. A lead screw 221 driven by the motor 17 to rotate is provided on the sliding seat 22. A slider 223 penetrates through the lead screw. The slider 223 is connected to the middle of the upper end of the rolling shutter door 21 and is used to pull the rolling shutter door 21 to move back and forth above the spray pipe 24 to open or close the opening of the cavity.

[0048] It should be noted that the rolling shutter door is an existing product, which is composed of multiple long strip-shaped curtain boards. The whole rolling shutter door has a certain flexibility and can be bent. The left and right ends of the rolling shutter door are slidably matched with the slide rails through rollers. There is no need to repeat its structure too much this time.

[0049] Under normal conditions, the rolling shutter door is located in the front side of the opening of the cavity to close the opening of the cavity; when it is necessary to take out or place the battery, the motor drives the lead screw to rotate, and the rotation of the lead screw drives the slider to move back and forth along the lead screw. The slider drives the whole rolling shutter door to move upward to open the opening of the cavity. By setting a rolling shutter door controlled by the motor to move up and down, when taking and placing the battery, it is only necessary to open or close the rolling shutter door, without repeatedly opening the cabinet door, which not only reduces the design difficulty of the cabinet door, but also improves the service life of the battery swapping cabinet.

[0050] In specific practice, refer to 2A- Figure 2D , the top plate 14 is a groove-shaped structure with a middle depression, the sliding seat 22 is arranged in the depression of the groove-shaped structure, and the top of the sliding seat 22 is lower than the top heights of the left side plate 11 and the right side plate 12.

[0051] The advantage of this setting is that the outer shape of the battery compartment module is regular, which is convenient for the battery compartment module to be placed into the battery swapping cabinet.

[0052] In specific practice, refer to Figures 2A - 2B , the left side plate 11 and the right side plate 12 are respectively provided with slide rails 23 at the opening. The slide rails 23 extend from the bottom of the opening of the left side plate 11 and the right side plate 12 to the top of the opening, and cross the water inlet hole A of the spray pipe 24, and extend to a preset distance from the back plate 16 of the top plate 14; the left and right ends of the rolling shutter door 21 are respectively slidably matched with the slide rails 23.

[0053] It can be understood that the setting of the slide rail is to play a guiding role in the up and down movement of the rolling shutter door.

[0054] It can be understood that the technical solution provided by this embodiment, through the ingenious design of the positional relationship between the spray pipe and the rolling shutter door, only requires a round hole to be opened on each of the left side plate and the right side plate to install the spray pipe, and the end of the spray pipe forms a water inlet hole A (see Figure 2A and Figure 2B shown), without modifying the installation position of the existing rolling shutter door, improving the feasibility of installation implementation and the compactness of the structure, with good user experience and high satisfaction, and greatly facilitating the product update and upgrade.

[0055] In specific practice, refer to Figure 2A , at the front and rear ends of the lead screw 221, a first Hall switch 18 and a second Hall switch 19 are respectively arranged beside;

[0056] The first Hall switch 18 is used to detect whether the rolling shutter door 21 is pulled to the preset opening position to ensure that the opening of the cavity is opened; the second Hall switch 19 is used to detect whether the rolling shutter door 21 is pulled to the preset closing position to ensure that the opening of the cavity is closed.

[0057] It can be understood that the setting of the first Hall switch 18 and the second Hall switch 19 improves the reliability of the opening and closing of the rolling shutter door.

[0058] See Figure 2A , a slide bar 222 is further arranged in the sliding seat 22, and the slide bar 222 is parallel to the lead screw 221;

[0059] The first Hall switch 18 and the second Hall switch 19 are respectively arranged at both ends of the slide bar 222.

[0060] Preferably, the slider 223 is an L-shaped slider. The long side of the L-shaped slider penetrates through the lead screw 221, the short side of the L-shaped slider is slidably arranged on the slide bar 222, and a magnet 20 is installed on the short side. The magnet 20 faces the detection surfaces of the first Hall switch 18 and the second Hall switch 19.

[0061] It can be understood that in the technical solution provided in this embodiment, the first Hall switch and the second Hall switch not only have the position detection function, but also have the limit function to limit the sliding position of the slider on the lead screw. The ingenious design of the first Hall switch, the second Hall switch and the slider structure increases the reliability of the opening and closing of the rolling shutter door, and at the same time makes the structure of the sliding seat compact, occupies less space and is convenient for deployment and implementation.

[0062] See Figure 2C , heating guide bars 26 are arranged on both the left side plate 11 and the right side plate 12; the heating guide bars 26 extend longitudinally inward along the left and right side walls of the battery compartment; the heating guide bars 26 are used to heat the battery at low temperature.

[0063] Preferably, there are two heating guide bars 26, which are symmetrically arranged on the left and right side walls of the battery compartment.

[0064] It can be understood that the setting of the heating guide bars ensures that the battery can work normally in a low-temperature environment and improves the reliability of the battery swapping cabinet.

[0065] See Figure 2A , a roller slide rail 15 is arranged on the bottom plate 13 along the battery inlet and outlet direction, and the roller slide rail 15 extends longitudinally inward along the bottom wall of the battery compartment; the roller slide rail 15 is used to limit the battery placed in the battery compartment, and at the same time change the sliding friction of the battery entering and leaving the battery compartment into rolling friction to reduce friction.

[0066] Preferably, there are two roller slide rails 15, which are arranged on the bottom wall of the battery compartment at a preset interval.

[0067] It should be noted that the roller slide rail 15 is a slide rail provided with a roller assembly.

[0068] It should be noted that as Figure 2B shown, a temperature sensor is also provided in the battery compartment module provided in this embodiment. The settings of the temperature sensor and the heat dissipation holes in the respective drawings are only examples, and the installation positions thereof are not specifically limited.

[0069] It can be understood that in the technical solution provided in this embodiment, by providing a roller slide rail along the battery access direction on the inner wall of the cavity and providing a spray pipe and a spray head for fire safety, on the premise of ensuring battery safety, when extracting and inserting the battery, the sliding friction is changed to rolling friction through the roller slide rail, which is beneficial to reducing friction, saving effort and improving the service life of the battery.

[0073] A charging module 200 is provided on the outer wall of the back plate of the battery compartment module 100, and a control board 300 connected to the charging module 200.

[0074] It should be noted that Figure 4 the battery swapping cabinet given is only an example, and does not mean that it is limited to this form of battery swapping cabinet. A charging module is provided on the outer wall of the back plate of the battery compartment module, and the charging module is used to charge the battery in the battery compartment.

[0075] It can be understood that in the technical solution provided in this embodiment, since it includes a battery compartment module, and the battery compartment module is provided with a spray pipe at the opening of the battery compartment cavity, and the spray pipe is directly connected to the water source, the fire fighting waterway can directly enter the battery compartment from the front of the battery compartment to extinguish the fire. Compared with the prior art in which a spray head is provided on the top of the battery compartment and water is supplied by capillary drainage from the main water supply pipe on the back of the battery compartment, the intricate capillary tubes are omitted, greatly simplifying the structure and waterway design of the battery compartment.

[0076] After multiple battery compartment modules are connected in series, the battery compartment modules on the same layer can reuse the same spray pipe. After the spray pipe is filled with water, it can supply water to each battery compartment on the same layer. Compared with the prior art in which multiple capillary tubes are used to drain water to the spray head from the back of the battery swapping cabinet, the technical solution provided in this embodiment greatly simplifies the fire-fighting water supply line of the battery compartment and saves product costs.

[0077] Furthermore, through the ingenious design of the positional relationship between the spray pipe and the rolling shutter door, only one round hole needs to be opened on each of the left side plate and the right side plate to install the spray pipe. The end of the spray pipe forms a water inlet hole, and there is no need to modify the installation position of the existing rolling shutter door, which improves the feasibility of installation implementation and the compactness of the structure, with good user experience and high satisfaction, and greatly facilitates the product update and upgrade.

[0078] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
