Description

Technical Field

[0001] This utility model relates to the field of battery swapping cabinet technology, and in particular to a battery swapping cabinet with automatic door closing. Background Technology

[0002] With the increasing popularity of personal transportation such as electric bicycles and electric motorcycles, providing convenient and fast battery replacement services for these devices has become increasingly important. Battery swapping stations, as self-service battery swapping stations specifically designed for electric vehicles, play a crucial role in urban transportation. Users can quickly replace the depleted batteries in their electric vehicles using these facilities without having to wait a long time for charging to complete. However, some operational problems have been discovered in practical applications, one of which is that users occasionally forget to close the battery swapping station door after replacing the battery.

[0003] Forgetting to close the cabinet door can not only expose internal equipment to external environmental factors (such as dust and moisture), but also pose safety hazards, such as unauthorized personnel touching internal components or malicious damage. Furthermore, an open door can disrupt the user experience, especially during peak hours. When multiple users consecutively use the same battery swapping cabinet, the previous user's failure to close the door directly impacts the subsequent user's workflow. Most existing battery swapping cabinets rely on manual door closing, which, while simple and direct, fails to address the root causes of negligence.

[0004] To address the aforementioned issues, we propose an automatic door-closing battery swapping cabinet. This cabinet can automatically close its door after a certain period of time. Summary of the Invention

[0005] To overcome the drawbacks of users forgetting to close the cabinet door, which can cause internal equipment to be affected by the external environment and lead to safety hazards, and also affect the normal use of other users, this utility model provides an automatic door closing battery swapping cabinet. This battery swapping cabinet can automatically close after the door has been open for a certain period of time.

[0006] The technical solution of this utility model is as follows: an automatic closing battery swapping cabinet, including a battery swapping cabinet body, a sunshade fixedly connected to the top of the battery swapping cabinet body, the battery swapping cabinet body being divided into two cavities, partitions evenly distributed in each of the two cavities being fixedly connected, mounting shafts evenly distributed in each of the battery swapping cabinet body being fixedly connected, a cabinet door being rotatably connected to the mounting shafts, and also including evenly distributed fixing blocks, which are fixedly connected to the two cavities of the battery swapping cabinet body, hollow cylinders being fixedly connected to the fixing blocks, piston rods being slidably connected inside the hollow cylinders, strip rails being fixedly connected to the piston rods, and elastic elements connecting the piston rods and adjacent hollow cylinders, an air inlet pipe with a one-way valve being connected to the hollow cylinders, an air outlet pipe with a one-way valve being connected to the hollow cylinders, the air outlet pipe being smaller than the air inlet pipe, heat dissipation components for ventilation and heat dissipation being provided on the battery swapping cabinet body and cabinet door, and guide components for preventing battery friction being provided on the partitions.

[0007] In one embodiment, the battery swapping cabinet has equidistantly distributed heat dissipation holes with an inclined structure that is higher on the inside and lower on the outside, in order to prevent water from flowing into the cabinet.

[0008] In one embodiment, the cabinet door has a slotted groove.

[0009] In one embodiment, a protruding rod is fixedly connected to the cabinet door, and the protruding rod is inserted into the adjacent strip rail.

[0010] In one embodiment, the heat dissipation assembly includes a horizontally symmetrical mounting plate fixedly connected to the battery swapping cabinet. Equally spaced temperature sensors are fixedly connected to the mounting plate, extending into the battery swapping cabinet. An alarm is fixedly connected to the top of the battery swapping cabinet. A guide rod is fixedly connected to the cabinet door, and horizontally symmetrical baffles are slidably connected to the guide rod. An electric guide rail is fixedly connected to the cabinet door, slidably connecting to two adjacent baffles. A cooling fan is fixedly connected to the cabinet door. The alarm, cooling fan, and electric guide rail are electrically connected to adjacent temperature sensors.

[0011] In one embodiment, the guide assembly includes a laterally symmetrical slide rail, which is fixedly connected to a partition plate. A slider is slidably connected inside the slide rail, and a support plate is fixedly connected between the laterally symmetrical sliders. A roller is rotatably connected to the front of the partition plate.

[0012] The beneficial effects are: 1. When the cabinet door is turned forward and opened, the piston rod slides forward and draws outside air into the hollow cylinder through the larger air intake pipe. The elastic element deforms. After the battery is replaced, the staff pushes the cabinet door to turn backward and close it. If the staff forgets to close the cabinet door, the elastic element resets and drives the piston rod to slide backward, thereby controlling the cabinet door to turn backward and close. Moreover, because the air intake pipe is small, the piston rod slides backward slowly due to the rebound of the elastic element without external pressure, so it will not affect the staff's inspection and replacement of batteries. In this way, the cabinet door can be automatically closed after a certain period of time, avoiding damage to the battery swapping cabinet and safety hazards caused by leaving the door open.

[0013] 2. When the temperature sensor detects that the temperature of the battery swapping cabinet is higher than the safe range, the temperature sensor will control the alarm to sound an alarm. At the same time, the electric guide rail controls the baffle to open, and the cooling fan will operate to allow air circulation in the battery swapping cabinet compartment, thereby dissipating heat from the battery swapping cabinet.

[0014] 3. When replacing the battery, the battery moves back and forth supported by the tray, and the roller also prevents the battery from rubbing directly against the separator, thus preventing battery damage. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] Example 1: An automatic door closing battery swapping cabinet, such as Figures 1-9 As shown, the device includes a battery swapping cabinet 1, a sunshade 2, partitions 3, mounting shafts 4, a cabinet door 5, a fixing block 6, a hollow cylinder 7, a piston rod 8, a strip rail 81, an elastic element 9, an air inlet pipe 10, an air outlet pipe 101, a heat dissipation assembly, and a guide assembly. The rear side of the battery swapping cabinet 1 has equidistantly distributed heat dissipation holes with an inclined structure (higher inside, lower outside) to prevent water from flowing into the cabinet. The sunshade 2 is fixedly connected to the upper side of the battery swapping cabinet 1. The battery swapping cabinet 1 is divided into left and right cavities. Five equidistantly distributed partitions 3 are fixedly connected to each of the left and right cavities of the battery swapping cabinet 1. Five equidistantly distributed mounting shafts 4 are fixedly connected to the middle and left sides of the front side of the battery swapping cabinet 1. A cabinet door 5 is rotatably connected to the mounting shaft 4. A strip groove is opened on the right side of the cabinet door 5. Five equidistant fixed blocks 6 are fixedly connected to the left side of both cavities of the battery swapping cabinet 1. Hollow cylinders 7 are fixedly connected to the fixed blocks 6. Piston rods 8 are slidably connected inside the hollow cylinders 7. Strip rails 81 are fixedly connected to the front end of the piston rods 8. Protruding rods are fixedly connected to the upper left side of the rear side of the cabinet door 5. The protruding rods are inserted into the adjacent strip rails 81. Elastic elements 9 are connected between the piston rods 8 and the adjacent hollow cylinders 7. An air inlet pipe 10 with a one-way valve is connected to the rear side of the hollow cylinder 7. An air outlet pipe 101 with a one-way valve is connected to the upper rear side of the hollow cylinder 7. The air outlet pipe 101 is smaller than the air inlet pipe 10. The battery swapping cabinet 1 and the cabinet door 5 are equipped with heat dissipation components for ventilation and heat dissipation. The partition 3 is equipped with guide components to prevent battery friction.

[0027] When using this device, after unlocking the cabinet door 5, the operator can pull the cabinet door 5 forward through the slot to open it. When the cabinet door 5 rotates forward, it drives the piston rod 8 to slide forward through the strip rail 81. The elastic element 9 deforms, and as the piston rod 8 slides forward, external air is drawn into the hollow cylinder 7 through the larger air intake pipe 10. After the cabinet door 5 is open, the operator can remove the battery from the battery swapping cabinet 1 to replace the depleted battery. After the battery is replaced, the operator pushes the cabinet door 5 backward to close it. The backward rotation of the cabinet door 5 drives the piston rod 8 to slide backward through the strip rail 81. When the elastic element 9 resets, the piston rod 8 slides backward to expel the air in the hollow cylinder 7 through the smaller air outlet pipe 101. If the staff forgets to close the cabinet door 5, the piston rod 8 will also slowly slide backward through the strip rail 81 under the reset action of the elastic element 9, pulling the cabinet door 5 to rotate backward and close. Since the air inlet pipe 10 is small, the piston rod 8 slides backward slowly due to the rebound of the elastic element 9 without external pressure, so it will not affect the staff's inspection and battery replacement. In this way, the cabinet door 5 can be automatically closed after being opened for a certain period of time.

[0028] Example 2: Based on Example 1, such as Figure 1 , Figure 6 and Figure 7 As shown, the heat dissipation assembly includes a mounting plate 11, a temperature sensor 12, an alarm 13, a guide rod 14, a baffle 15, an electric guide rail 16, and a cooling fan 17. Mounting plates 11 are fixedly connected to both the left and right sides of the battery swapping cabinet 1. Five temperature sensors 12 are fixedly connected to the mounting plates 11 at equal intervals. The temperature sensors 12 extend into the battery swapping cabinet 1. An alarm 13 is fixedly connected to the upper side of the battery swapping cabinet 1. A guide rod 14 is fixedly connected to the lower front side of the cabinet door 5. A symmetrical baffle 15 is slidably connected to the guide rod 14. An electric guide rail 16 is fixedly connected to the upper front side of the cabinet door 5. The electric guide rail 16 is slidably connected to two adjacent baffles 15. A cooling fan 17 is fixedly connected to the cabinet door 5. The alarm 13, the cooling fan 17, and the electric guide rail 16 are electrically connected to the adjacent temperature sensors 12.

[0029] When using this device, the temperature sensor 12 can monitor the temperature of each compartment in the battery swapping cabinet 1. When the temperature sensor 12 detects that the temperature is higher than the safe range, the temperature sensor 12 will control the alarm 13 to operate and sound an alarm. At the same time, it will also control the operation of the electric guide rail 16 and the cooling fan 17. The electric guide rail 16 controls the two baffles 15 on the left and right to open, and the operation of the cooling fan 17 can make the air in the compartment of the battery swapping cabinet 1 circulate, thereby dissipating heat in the battery swapping cabinet 1. When the temperature returns to the normal range, the electric guide rail 16 controls the two baffles 15 to close, and the cooling fan 17 will turn off.

[0030] like Figure 8 and Figure 9As shown, the guide assembly includes a slide rail 18, a slider 19, a support plate 20, and a roller 21. The upper side of the partition 3 is fixedly connected to the left and right symmetrical slide rails 18. The slider 19 is slidably connected inside the slide rail 18. The support plate 20 is fixedly connected between the left and right sliders 19. The upper front part of the partition 3 is rotatably connected to the roller 21.

[0031] When the battery is placed into the battery swapping cabinet 1, the end of the battery entering the cabinet 1 is supported on the tray 20. At this time, the staff can push the battery backward, which will cause the tray 20 to move backward. The slider 19 then slides backward in the slide rail 18. As the battery moves backward, it rotates on the roller 21. The cooperation between the roller 21 and the tray 20 can prevent the battery from being damaged by friction with the separator 3 when picking up and putting down the battery.
