Description

Technical Field

[0001] This utility model relates to a battery discharge device. Background Technology

[0002] Currently, the main treatments for tumors include surgery, radiotherapy, and chemotherapy, but all have corresponding drawbacks. For example, radiotherapy and chemotherapy can cause side effects and kill normal cells. Using electric fields to treat tumors is also at the forefront of research. Tumor Treating Fields (TTF) is a method that applies a low-intensity, medium-frequency alternating electric field to cancer cells, thereby interfering with the mitotic process of cancer cells, inhibiting mitosis, and inducing apoptosis, thus achieving a therapeutic effect. The electric field therapy equipment used to treat tumors mainly includes a tumor electric field therapy device main unit and electrode patches electrically connected to the main unit. The electrode patches are applied to the skin corresponding to the lesion, thus applying the alternating electric field to the tumor tissue area for electric field tumor therapy.

[0003] Existing tumor electric field therapy devices can be powered by plugging in batteries to improve portability. Batteries need to be discharged during manufacturing. Existing battery discharge equipment connects the battery to be tested to the battery and discharges it. It is equipped with an indicator unit that can issue corresponding indication information after the battery discharge is completed, so that the tester can remove the battery from the battery discharge equipment in time to prevent the battery from being over-discharged.

[0004] However, the discharge modules in existing battery discharge devices generate high temperatures during the discharge process. Although they are generally equipped with heat dissipation designs, they cannot accurately monitor the internal temperature of the battery discharge device, and there is still a risk that the internal electrical components may be damaged due to excessive temperature.

[0005] Therefore, existing battery discharge equipment needs to be improved to solve the above problems. Utility Model Content

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of implementations consistent with some aspects of this application.

[0022] refer to Figures 1 to 8 As shown, this utility model relates to a battery discharge device 100 for discharging multiple batteries 200. It has a generally box-shaped outer shell 10 consisting of a shell body 11 and a shell cover 12 covering the shell body 11. The shell body 11 is provided with a main control board 20 and an indicator board 40, a battery plug-in board 30, a temperature control module 60, a first cooling fan 16, a second cooling fan 17, and a discharge module 51, which are electrically connected to the main control board 20. Furthermore, the shell body 11 is also provided with a power module 70 electrically connected to the temperature control module 60, a power interface module 80 electrically connected to the power module 70, and a heat sink 50 located on the discharge module 51.

[0023] The battery connector board 30 is electrically connected to the discharge module 51 via the main control board 20 and is configured to be electrically connected to the battery 200 that needs to be discharged and to discharge the corresponding battery 200. The indicator board 40 is configured to indicate the discharge state of the corresponding battery 200. The main control board 20 is configured to control the discharge module 51 to discharge the corresponding battery 200, and to collect the voltage of the corresponding battery 200 and control the indicator board 40 to indicate the discharge state of the corresponding battery 200 according to the voltage. The temperature control module 60 has a temperature protection threshold and can monitor the temperature of the heat sink 50 in real time. When the temperature control module 60 detects that the real-time temperature of the heat sink 50 exceeds the set temperature protection threshold, it can cut off the power supply from the power module 70 to the main control board 20 and issue an alarm, thereby cutting off the power supply path of the main control board 20 and causing the other electrical components electrically connected to the main control board 20 to stop working. The power module 70 is configured to be electrically connected to the temperature control module 60, and then electrically connected to the main control board 20 to supply power to the battery discharge device 100.

[0024] Continue to refer to Figure 2 As shown, in this embodiment, one side of the cover 12 is pivotally connected to a corresponding part of the body 11 via at least two connectors 18, allowing the cover 12 to be opened or closed relative to the body 11. The connectors 18 can be connecting shafts or hinges. The outer casing 10 may also be provided with two housing latches 14 located on opposite sides. These latches 14 are used to connect the body 11 and the cover 12, and when locked, they can fix the cover 12 to the body 11, preventing the cover 12 from opening relative to the body 11 due to improper operation during testing, thus preventing external dust and moisture from entering the electrical components inside the outer casing 10 and causing damage.

[0025] Combination Figures 3 to 5As shown, a vertical partition plate 15 is provided inside the main body 11 along the front-to-back direction. The partition plate 15 divides the installation space (unlabeled) inside the main body 11 into a first cavity 111 for accommodating the heat sink 50 and the discharge module 51, and a second cavity 112 for accommodating the main control board 20, the indicator board 40, the battery connector board 30, the temperature control module 60, the power module 70, and the power interface module 80. The partition plate 15 is provided with a wire-passing hole 150 connecting the first cavity 111 and the second cavity 112 to facilitate the connection and wiring of the above-mentioned electronic components. The heat sink 50 is generally rectangular in shape, and the discharge module 51 is located at its bottom. The discharge module 51 includes multiple discharge loads RL, and multiple heat dissipation fins 52 are arranged side by side on the side of the heat sink 50 opposite to the discharge module 51. The size of the heat sink 50 is slightly smaller than the size of the bottom shell wall of the main body 11 corresponding to the first cavity 111. The front and left and right sides of the heat sink 50 are closely attached to the inner wall of the main body 11 and the partition plate 15. The rear side of the heat sink 50 and the inner wall of the housing 11 form an open space (unlabeled) to accommodate four first cooling fans 16 arranged in a row. The housing 11 is provided with corresponding first air outlets 160 for each of the four first cooling fans 16, which are used to exhaust the heat generated by the multiple discharge loads RL located at the bottom of the heat sink 50 through the radiation of multiple heat dissipation fins 52 and then through the airflow of the four first cooling fans 16 to the outside of the housing 11.

[0026] Combination Figure 4 and Figure 6As shown, the battery connector plate 30 is located at the front of the second cavity 112, and has twelve battery sockets 31 arranged in a four-row, three-column array. The battery connector plate 30 also has a battery compartment 32 corresponding to each row of battery sockets 31. Each battery compartment 32 has a corresponding battery insert 33 corresponding to the three battery sockets 31 in the corresponding row. That is, each battery compartment 32 has three battery inserts 33. Each battery insert 33 has a battery socket 34 with a shape corresponding to the outer shell of the battery 200. The cover 12 has four strip-shaped first openings 121 corresponding to the four battery compartments 32. When the cover 12 is closed to the body 11, the battery inserts 33 in each battery compartment 32 are exposed in the corresponding first opening 121, and the bottom of each battery insert 33 exposes the corresponding battery socket 31. The tester can insert the battery 200 into the corresponding battery insert 33 through the battery socket 34 and connect it to the corresponding battery socket 31 on the battery connector plate 30. When the cover 12 is closed relative to the main body 11, the main control board 20, the indicator board 40, and the power module 70 are located at the rear end of the second cavity 112. Specifically, the power module 70 is fixed to the partition plate 15, the main control board 20 is located to the right of the power module 70, and the indicator board 40 is located directly above the main control board 20. A second cooling fan 17 is also provided on the rear inner wall of the main body 11 corresponding to the power module 70. A second air outlet 170 is provided on the main body 11 corresponding to the second cooling fan 17 to exhaust the heat generated by the electrical components located in the second cavity 112 to the outside of the main body 11 via the second cooling fan 17.

[0027] refer to Figure 4 and Figure 5As shown, the indicator panel 40 is provided with multiple sets of sound and light indicator units 41. Each set of sound and light indicator units 41 includes a light-emitting diode D1 and a buzzer B1. In this embodiment, the indicator panel 40 is provided with twelve sets of sound and light indicator units 41. Each set of sound and light indicator units 41 corresponds to a battery socket 31. The main control board 20 is electrically connected to the indicator panel 40 through wires (not shown) to realize the electrical connection between the main control board 20 and the multiple sets of sound and light indicator units 41. The cover 12 has twelve sets of clearance holes 13 corresponding to the twelve sets of sound and light indicator units 41. Each set of clearance holes 13 includes a first clearance hole 131 and a second clearance hole 132. Each first clearance hole 131 corresponds to the light-emitting diode D1 of each set of sound and light indicator units 41, allowing the light-emitting diode D1 to pass through the first clearance hole 131 and protrude from the cover 12. Each second clearance hole 132 corresponds to the buzzer B1 of each set of sound and light indicator units 41, allowing the buzzer B1 to pass through the second clearance hole 132 and protrude from the cover 12, making it convenient for testers to observe the light emitted by the light-emitting diode D1 and hear the sound emitted by the buzzer B1. In other optional embodiments, the clearance holes 13 can also be single holes, with each clearance hole 13 corresponding to a set of sound and light indicator units 41, that is, each set of light-emitting diode D1 and buzzer B1 is arranged to be exposed in a corresponding clearance hole 13. The temperature control module 60 is roughly rectangular and located on the left side of the indicator plate 40. Above it is a display screen 61, which is used to display the temperature of the heat sink 50 monitored by the temperature control module 60.

[0028] The cover 12 is also provided with a second opening 122 corresponding to the temperature control module 60. The shape and size of the second opening 122 are similar to the shape and size of the bottom of the temperature control module 60. The shape and size of the display screen 61 are slightly larger than the shape and size of the second opening 122. With this arrangement, the temperature control module 60 can pass through the second opening 122 from outside the cover 12 and enter the second cavity 112 and be electrically connected to the main control board 20 through a wire (not shown). The display screen 61 can be mounted at the second opening 122 and exposed outside the cover 12, making it convenient for testers to observe the temperature of the heat sink 50 displayed on it.

[0029] Combination Figure 7 As shown, the rear sidewall of the housing 11, corresponding to the second cavity 112, also has a third opening 123. The power interface module 80 is a rectangular block located at the third opening 123. It has a power interface 81 and a power switch 82 both exposed outside the housing 11. The power interface module 80 passes through the third opening 123 into the second cavity 112 and is electrically connected to the power module 70 via a wire (not shown). The power interface 81 is configured to be electrically connected to a power adapter (not shown) to supply power to the battery discharge device 100.

[0030] Back Figure 3As shown, the shell body 11 is also provided with multiple heat dissipation grilles 90 corresponding to the electrical components in the first cavity 111 and the second cavity 112. Each heat dissipation grille 90 is composed of multiple small heat dissipation holes (unlabeled) penetrating the shell body 11. Specifically, the shell body 11 is provided with a first heat dissipation grille 91 on the front side wall and bottom wall corresponding to the first cavity 111, and a second heat dissipation grille 92 is provided on the bottom wall corresponding to the power module 70 and the main control board 20 in the second cavity 112, so as to further improve the heat dissipation efficiency of the electrical components in the first cavity 111 and the second cavity 112.

[0031] When the battery discharge device 100 discharges the battery 200, the audible and visual indicator unit 41 exposed on the casing 12 indicates the discharge state of the corresponding battery 200. The discharge state of the battery 200 can include whether the battery 200 is discharging, whether the battery 200 has finished discharging, or whether the actual voltage of the battery 200 is less than the preset discharge voltage of the battery 200. The "preset discharge voltage" refers to the voltage at which the battery 200 is to be finally discharged, which is preset in the program of the main control board 20. During discharge detection, the battery discharge device 100 is connected to the adapter and the battery 200 is inserted into the battery compartment 32 from the battery socket 34. The battery socket 30 detects the actual voltage of the battery 200 (i.e., the voltage of the battery 200 when it is not discharged) and transmits the voltage signal to the main control board 20. After the main control board 20 analyzes the voltage signal, it can determine that a battery 200 is connected to the battery discharge device 100. The main control board 20 compares the actual voltage of the battery 200 with the preset discharge voltage. If the actual voltage of battery 200 is greater than the preset discharge voltage, the main control board 20 controls the discharge module 51 to conduct the discharge circuit so that the discharge module 51 discharges the corresponding battery 200. At the same time, the main control board 20 controls the light-emitting diode D1 of the sound and light indicator unit 41 to flash to indicate that the battery 200 is discharging, thereby reminding the tester that the battery 200 is discharging. After the battery 200 discharges to the preset discharge voltage, the main control board 20 controls the discharge module 51 to cut off the discharge circuit so that the battery 200 stops discharging. At the same time, the main control board 20 controls the light-emitting diode D1 of the sound and light indicator unit 41 to stay lit and the buzzer B1 to sound continuously to indicate that the battery 200 has finished discharging, thereby reminding the tester that the battery 200 has been discharged to the target capacity (i.e., the preset discharge voltage). The tester can then remove the battery 200 from the battery compartment 32. After the battery 200 is removed, the buzzer B1 will stop sounding and the light-emitting diode D1 will turn off. If the actual voltage of battery 200 is less than or equal to the preset discharge voltage, the main control board 20 controls the LED D1 of the sound and light indicator unit 41 to stay lit and the buzzer B1 to sound continuously, so as to remind that the actual voltage of battery 200 is less than the preset discharge voltage of battery 200, indicating that the battery 200 connected to the battery discharge device 100 has an incorrect charge.

[0032] The battery discharge device 100 provided by this utility model can perform discharge tests on multiple batteries 200. By setting the discharge module 51 on the heat sink 50 and additionally setting the temperature control module 60 electrically connected to the main control board 20, the heat dissipation efficiency is effectively enhanced and the discharge efficiency is improved. At the same time, it also has the function of automatically terminating the discharge when the temperature is too high. This can prevent the internal temperature of the device from being too high and damaging the electrical components under abnormal conditions. It can also avoid the situation where high temperature is conducted to the outer shell and burns the operator, thus improving the safety of the device.

[0033] The above are merely preferred embodiments of this application and are not intended to limit this application.
