Description

Technical Field

[0001] The utility model belongs to the technical field of charging boxes, and relates to an intelligent charging box, in particular to an intelligent charging box for dynamic electrocardiogram devices. Background Technique

[0002] Existing dynamic electrocardiogram devices generally have a lithium battery with a relatively small built-in capacity. When the battery of the electrocardiogram device has a low power, it needs to be charged by plugging an external charging cable into a power source, and the charging stops automatically after being fully charged. Only by plugging and unplugging the charging cable again can it be detected whether the electrocardiogram device needs to be charged. After the electrocardiogram device is placed for half a year, the self-power consumption is completed, which will cause over-discharge of the battery, resulting in physical damage, thus greatly reducing the battery life. Since the dynamic electrocardiogram device needs to be attached to the human body to collect electrocardiograms, and most of the dynamic electrocardiogram devices are made of silica gel, it is very important to keep the dynamic electrocardiogram recorder clean. The electrocardiogram device placed anywhere may be polluted by the external environment, or may be in a state of excessive bending or stretching, which will affect the product life. Therefore, an intelligent charging box is designed to overcome the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and to provide an intelligent charging box with a simple and reasonable structure, which can well protect the electrocardiogram device and the internal battery, ensure the natural placement of the electrocardiogram device, can keep it in a clean state, and can also prevent it from being contaminated by other corrosive liquids and causing damage to the electrodes, thus greatly improving the service life.

[0004] The utility model is realized by the following technical solutions: An intelligent charging box, which includes a charging box body. The charging box body is composed of an upper box body and a lower box body. The upper box body and the lower box body are connected by a connecting shaft provided on one side, and a locking device is provided on the other side opposite to the connecting shaft. The upper box body and the lower box body are locked by the locking device. A groove for placing the electrocardiogram device is opened inside the lower box body. A plurality of limiting grooves are opened in the groove, and a chamber for placing the battery and the control board is opened at the bottom. The chamber is covered by a bottom plate.

[0005] Preferably: A plurality of limiting strips and fixing seats are opened inside the lower box body. The control board is fixedly installed in the limiting strips and the fixing seats, and the control board is fixed in the area surrounded by the plurality of limiting strips. The control board is connected to the battery on one side through a cable. Two through holes penetrating the lower box body are opened at the control board. A contact is installed in the through hole. One end of the contact is fixed on the control board, and the other end is installed in the through hole. A contact groove facing the electrocardiogram device is provided above. The electrocardiogram device is charged by the contact contacting the contact groove. An indicator light hole and a TYPE-C charging hole are also opened on the side edge of the lower box body for placing the indicator light and the TYPE-C interface.

[0006] Preferably, a power control chip, an MCU control chip, an output chip, and a voltage detection chip are installed on the control board. The MCU control chip is respectively connected to the power control chip, the output chip, and the voltage detection chip. The power control chip is connected to the battery, the TYPE-C interface, and the contact. When the power control chip controls the battery and the TYPE-C interface, the battery in the box is charged. When the power control chip controls the battery and the contact, the battery in the box discharges to charge the electrocardiogram device. The voltage detection chip is connected to the battery in the box and the contact. When it detects that the battery in the box or the electrocardiogram device has a low power level, it feeds back through the MCU control chip to the output chip to make the indicator light flash or directly starts the power control chip to charge the electrocardiogram device.

[0007] Preferably, a Hall element is also installed on the control board, and the locking device is a magnet and an iron sheet provided on the upper box body and the lower box body. A Hall switch is formed between the magnet and the Hall element. The Hall switch is connected to the MCU control chip. When the upper box body is opened, the Hall voltage changes. The MCU control chip controls the power control chip to start the voltage detection chip of the charging box to detect the power level of the battery in the box. The output chip displays the indicator light for 3S to indicate a low power level to remind the user to charge.

[0008] Preferably, the magnet in the upper box body is fixed in a card slot on the side of the upper box body facing the lower box body, and the iron sheet in the lower box body is installed in a groove below the lower box body and corresponds to the magnet in the upper box body.

[0009] Preferably, a lifting part is also provided on the outer side of the magnet on the upper box body and the lower box body. The lifting part on the upper box body is a protruding handle, and the lifting part of the lower box body is two limiting strips, which play a role in limiting and anti-slip and facilitate opening the box body.

[0010] The beneficial effects of the present utility model are as follows: By placing the electrocardiogram device in the charging box for charging, this charging method can well ensure that the dynamic electrocardiogram device (recorder) itself for electrocardiogram acquisition attached to the human body after charging is clean. Moreover, when stored in the charging box for charging, physically, the recorder can be kept free from external forces, in a clean state, and prevent contamination by other corrosive liquids from causing damage to the electrodes. And, the MCU control chip on the control board of the present utility model can automatically replenish the power of the device to ensure the product life. The charging box of the present utility model adopts a low-power design and usually operates in a low-power mode to save power. When the state of opening and closing the upper box body changes, or when the power level of the dynamic electrocardiogram recorder is lower than the set threshold, the MCU will be awakened to work, display the charging state, and automatically enter the low-power state again when charging is completed and there is no operation, thus greatly reducing unnecessary energy waste.

Moreover, when stored in the charging box for charging, physically, the recorder can be kept free from external forces, remain clean, and prevent being contaminated by other corrosive liquids, causing damage to the electrodes.

[0020] As Figure 4As shown in the figure, multiple limiting strips 10 and fixing seats 11 are provided inside the lower box body 2. A control board 7 is fixedly installed inside the limiting strips 10 and the fixing seats 11. The control board 7 is fixed within the area surrounded by the multiple limiting strips 10. The control board 7 is connected to a battery 6 on one side through a cable 12. Two through holes 13 penetrating the lower box body 2 are provided on the control board 7. A contact 14 is installed inside the through hole 13. One end of the contact 14 is fixed on the control board 7, and the other end is installed in the through hole 13. The contact 14 is directly opposite to a contact slot of the electrocardiogram device (not shown in the figure) above. By contacting the contact slot with the contact 14, the electrocardiogram device is charged. An indicator light hole and a TYPE-C charging hole are also provided on the side of the lower box body 2 for placing an indicator light 15 and a TYPE-C interface 16.

[0021] As Figure 5 shown, a power control chip 17, an MCU control chip 18, an output chip 19, and a voltage detection chip 20 are installed on the control board 7. The MCU control chip 18 is respectively connected to the power control chip 17, the output chip 19, and the voltage detection chip 20. Among them, the power control chip 17 is connected to the battery 6, the TYPE-C interface 16, and the contact 14. When the power control chip 17 controls the battery 6 and the TYPE-C interface 16, the battery 6 inside the box is charged. When the power control chip 17 controls the battery 6 and the contact 14, the battery 6 inside the box discharges to charge the electrocardiogram device. The voltage detection chip 17 is connected to the battery 6 and the contact 14 inside the box. When it detects that the battery 6 or the electrocardiogram device has a low power, it feeds back to the output chip 19 through the MCU control chip 18 to make the indicator light 15 flash or directly start the power control chip 17 to charge the electrocardiogram device.

[0022] A Hall element 21 is also installed on the control board 7, and the locking device is two magnets 22 provided on the upper box body 1 and the lower box body 2. A Hall switch 27 is formed between the magnet 22 and the Hall element 21. The Hall switch 27 is connected to the MCU control chip 18. When the upper box body 1 is opened, the Hall voltage changes. The MCU control chip 18 controls the power control chip 17 to start the voltage detection chip to detect the power of the battery 6 inside the charging box. The output chip 19 displays the indicator light 15 for 3S to prompt a low power, which is used to remind the user to charge. The Hall switch in the present utility model is a prior art, so its working principle will not be described in detail.

[0023] The magnet 22 in the upper box body 1 is fixed in the card slot 23 on the side of the upper box body 1 facing the lower box body 2. The magnet 22 in the lower box body 2 is installed in the groove 26 below the lower box body 2 and corresponds to the magnet 22 in the upper box body 1. A lifting part is also provided on the outer side of the magnet 22 on the upper box body 1 and the lower box body 2. The lifting part on the upper box body 1 is a protruding handle 24, and the lifting part of the lower box body 2 is two limiting strips 25, which play a limiting role and facilitate opening the box body. The utility model is convenient to open and close through the provided handle and two limiting strips.

[0024] The functional characteristics of the utility model are as follows:

[0025] 1. Intelligent detection and supplementary power

[0026] The intelligent charging box of the utility model can, through the built-in control board and the MCU control chip, detect the power of the dynamic electrocardiogram recorder in real time. When the power is lower than the set threshold, the MCU control chip feeds back to the output chip to make the indicator light 15 flash or directly start the power control chip to charge the electrocardiogram device, ensuring that the power of the dynamic electrocardiogram device (recorder) is sufficient, protecting the product's battery life, preventing physical damage to the battery caused by over-discharge and inability to support the claimed battery life. At the same time, when the user takes out the dynamic electrocardiogram recorder at any time, it can be directly used without prior charging, which is convenient for the user.

[0027] After the dynamic electrocardiogram recorder is fully charged, the charging will automatically stop to prevent battery damage caused by overcharging the battery. The charging will restart automatically when the power is lower than the threshold next time. This charging method greatly saves power costs and increases the service life of the charging box.

[0028] Through the setting and detection of the threshold, frequent charging of the electrocardiogram recorder is prevented, shortening the battery life of the electrocardiogram recorder. At the same time, it also avoids the charging box repeatedly waking up the MCU to work and consuming power.

[0029] 2. Intelligent status reminder

[0030] The intelligent charging box of the utility model is internally provided with a Hall switch, which consists of a magnet embedded in the upper box body and a Hall element on the control board. Under the condition that the charging box is not connected to an external power supply, when the upper box body is opened, the Hall voltage changes, and the charging box starts to detect the power of the battery inside the box. The indicator light displays for 3S to prompt whether the power is low, so as to remind the user to charge.

[0031] Battery charging status indication inside the box: orange and green dual-color light

[0032] 1) When connected to an external power supply, the orange light is always on: charging; the green light is always on: fully charged;

[0033] 2) When the external power supply is removed, the light goes out.

[0034] When the upper cover changes from closed to open state:

[0035] Orange light is always on: When the battery level ≥ 20%, it is always on for 3 s and then goes out;

[0036] Orange light blinks: When the battery level is lower than 20%, it blinks for 3 s (blinking once per second) and then goes out;

[0037] Off: No power or malfunction;

[0038] ECG recorder charging status indication: Orange light, always on: Charging; Off: Fully charged.

[0039] 3. Low-power design (in a low-power state when fully charged)

[0040] The intelligent charging box of the present utility model adopts a low-power design and usually operates in a low-power mode to save power. When the state of the upper box body changes during opening and closing, or when the battery level of the dynamic ECG recorder is lower than the set threshold, the MCU will be awakened to work, display the charging status, and automatically enter the low-power state again after charging is completed and there is no operation. This method ensures the effective utilization of the charging box battery and achieves a longer service life.

[0041] 4. Integration of physical storage and charging functions

[0042] The dynamic ECG device (recorder) needs to be attached to the human body to collect ECG. It is very important to keep the dynamic ECG recorder clean. Most of the dynamic ECG recorders are made of silicone material. If they are in a state of being bent or stretched too much for a long time during storage, or in a dirty environment, it will affect the product life.

[0043] The present utility model stores the dynamic ECG device (recorder) in the designed intelligent charging box. Physically, it can not only keep the recorder free from external forces, but also keep it clean, and prevent it from being contaminated by other corrosive liquids and causing damage to the electrodes. Functionally, the charging box can automatically replenish the power of the device to ensure the product life.
