Description

Technical Field

[0002] A defibrillator is a medical device that uses a strong pulse current to pass through the heart to eliminate arrhythmias and restore sinus rhythm. It is an essential first aid device for all departments of a hospital. Defibrillation is one of the most important steps in cardiopulmonary resuscitation. With the advancement of technology, some portable defibrillators have appeared on the market. These defibrillators can be used by non-professionals to rescue patients with sudden cardiac death. They are currently widely installed in public places such as airports, stadiums, and schools. Portable defibrillators are generally powered by batteries. When the battery is low, it needs to be charged. The usual way is to remove the battery from the defibrillator and install it on the impulse device for charging.

[0003] Most existing charging devices lack a locking mechanism. When placing a battery in a charging device for charging, if an external force slightly touches the battery, the battery and the charging device may become loose, causing charging interruption. In order to solve this problem, some charging devices have a cover plate attached to the outside of the battery during charging, and then the cover plate is snapped onto the charging device. Although this can reduce the probability of battery loosening, it also brings troubles to installation and removal, which inevitably affects the efficiency of use; and when not charging, it is also troublesome to store the cover plate, which is easy to get lost.

[0026] like Figure 1 , 2 As shown, a defibrillator battery charging device includes a charging seat 1, in which two charging slots 11 are provided. The charging slots 11 are used to place batteries for charging. The defibrillator battery charging device can charge two batteries at the same time. Each charging slot 11 is provided with a battery connector 2, which is used to be electrically connected to the battery, so as to facilitate charging the battery. A clamping mechanism and a limit block 3 are provided in the charging slot 11. The clamping mechanism is detachably connected to the battery and is used to clamp and fix the battery so that the battery can be fixed in the charging slot 11; the limit block 3 is movably connected to the charging seat 1, and the limit block 3 can be connected to the battery, so that the battery is fixed in the charging slot 11 during charging, so as to prevent the battery from loosening and causing charging interruption. An unlocking mechanism is provided on the charging seat 1, and the unlocking mechanism is connected to the limit block 3. The unlocking mechanism can drive the limit block 3 to extend or retract into the charging slot 11.

[0027] Specifically, when charging is required, the battery is inserted into the battery connector 2 of the charging slot 11 to electrically connect the battery to the battery connector 2; the battery is fixedly engaged with the snap-fit ​​mechanism, and then the unlocking mechanism is operated to extend the limit block 3 out of the charging slot 11 and abut against the battery; at this time, the battery is firmly held in the charging slot 11 for charging by the force of the snap-fit ​​mechanism and the limit block 3. After charging is completed, the limit block 3 is driven to retract into the charging slot 11 by operating the unlocking mechanism to disengage it from the abutment with the battery; the battery can then be pulled out of the snap-fit ​​mechanism and the battery connector 2 by holding the battery, thereby removing the battery from the charging stand 1.

[0028] In this embodiment, the snap-in mechanism includes snap-in blocks 4 symmetrically arranged on the left and right side walls of the charging slot 11, and the charging slot 11 is provided with two snap-in blocks 4 on the left and right side walls respectively, and the shape of the snap-in blocks 4 is adapted to the shape of the corresponding snap-in slots on the battery; when the battery is inserted into the battery connector 2, the snap-in blocks 4 can be respectively inserted into the corresponding snap-in slots on the battery, so that the battery can be fixed in the charging slot 11. In other embodiments, the snap-in mechanism can also be adaptively modified according to the specific shape of the battery, and it is only necessary to ensure that the snap-in mechanism can be detachably snap-in with the battery, for example: a snap-in slot is provided on the side wall of the charging slot 11, and a snap-in block 4 is provided on the outer side wall of the battery; and in other embodiments, the number of snap-in blocks 4 can also be any other number.

[0029] A charging connector 5 is provided on the side wall of the charging station 1. The charging connector 5 is electrically connected to the battery connector 2. The charging connector 5 is used to charge the battery with an external power source. In this embodiment, there are two types of charging connectors 5, which can be used for two different power adapters; in other embodiments, the charging connectors 5 can also be any other number and type.

[0030] like Figure 2-5 As shown, the unlocking mechanism includes a pressing member 6 and a connecting member 7. The two ends of the connecting member 7 are fixedly connected to the pressing member 6 and the limit block 3 respectively. The pressing member 6 is movably connected to the charging seat 1. By operating the pressing member 6, the connecting member 7 can be driven to move, thereby driving the limit block 3 to extend or retract the charging slot 11; the connecting member 7 is used to transmit the driving force. The connecting member 7 is in the shape of the letter "L" as a whole, and there are multiple reinforcing ribs 71 distributed at equal distances on the outer wall of the connecting member 7, thereby improving the structural strength of the connecting member 7 and ensuring the stability of the transmission. In other embodiments, the connecting member 7 can also be any other shape according to actual design requirements.

[0031] Specifically, the charging stand 1 is provided with a mounting groove 12, one end of the pressing member 6 passes through the mounting groove 12 and is fixedly connected to the connecting member 7, and the other end of the pressing member 6 is provided with a pressing head 61, the pressing head 61 is integrally formed with the pressing member 6, and the pressing head 61 is slidably connected to the mounting groove 12. When in use, by operating the pressing head 61 to slide in the mounting groove 12, the pressing head 61 drives the pressing member 6 and the connecting member 7 to move, thereby driving the limit block 3 to extend or retract into the charging groove 11.

[0032] In order to enable the pressing member 6 to automatically reset, a reset mechanism is provided on the pressing member 6, and the reset mechanism is used to drive the pressing member 6 to extend out of the charging seat 1. When in use, when the user presses the pressing member 6, the pressing member 6 will squeeze the reset mechanism; when the user releases the pressing member 6, the pressing force on the pressing member 6 disappears, and the reset mechanism can push the pressing member 6 out of the charging seat 1.

[0033] The reset mechanism includes a reset spring 8, which is sleeved on the periphery of the pressing member 6, and one end of the reset spring 8 abuts against the pressing head 61, and the other end abuts against the upper end surface of the mounting slot 12. In the initial state, the pressing head 61 extends out of the upper end surface of the charging seat 1, and the limit block 3 also extends into the charging slot 11; when in use, the user presses the pressing head 61 to make the pressing head 61 slide down in the mounting slot 12, and the pressing head 61 will compress the reset spring 8, and at the same time, the pressing head 61 drives the connecting member 7 and the limit block 3 to move, so that the limit block 3 retracts into the charging slot 11; when the user releases the pressing head 61, the elastic force of the reset spring 8 will push the pressing head 61 to slide upward in the mounting slot 12, and the pressing head 61 drives the connecting member 7 and the limit block 3 to move, so that the limit block 3 re-extends into the charging slot 11.

[0034] A first sealing ring 9 is sleeved on the outer wall of the pressing head 61, and the first sealing ring 9 is slidingly and sealingly connected to the side wall of the mounting groove 12. The first sealing ring 9 can improve the sealing of the connection between the pressing head 61 and the charging base 1, prevent dust, water vapor, etc. from entering into the unlocking mechanism, improve the stability of the structure, and extend the service life.

[0035] A second sealing ring 10 is sleeved on the outer wall of the limit block 3, and the second sealing ring 10 is slidably and sealedly connected to the charging stand 1. The second sealing ring 10 can improve the sealing performance of the connection between the limit block 3 and the charging stand 1, prevent dust, water vapor, etc. from entering the unlocking mechanism, improve the stability of the structure, and extend the service life.

[0036] Working principle:

[0037] In the initial state, the pressing head 61 extends out of the upper end surface of the charging seat 1 , and the limiting block 3 extends into the charging slot 11 .

[0038] When the battery needs to be charged, first press the pressing head 61 so that the pressing head 61 slides down in the mounting slot 12. The pressing head 61 compresses the reset spring 8. At the same time, the pressing head 61 drives the connector 7 and the limit block 3 to move, so that the limit block 3 retracts into the charging slot 11. Then align the battery with the battery connector 2 and the clamping block 4, electrically connect the battery connector 2 to the battery, and insert the clamping blocks 4 into the clamping slots on the battery, so that the battery is limited in the charging slot 11. Then release the pressing head 61. Under the elastic force of the reset spring 8, the pressing head 61 is pushed to slide upward in the mounting slot 12. The pressing head 61 drives the connector 7 and the limit block 3 to move, so that the limit block 3 extends back into the charging slot 11 and abuts against the battery limit, firmly limiting the battery in the charging slot 11, so that the battery and the battery connector 2 are connected and fixed, ensuring that the battery will not loosen during the charging process. Then, it is connected to an external power source through the charging connector 5, and the battery is charged by the external power source.

[0039] When the battery needs to be removed after charging is completed, first press the pressing head 61 so that the pressing head 61 slides down in the installation slot 12. The pressing head 61 will compress the reset spring 8. At the same time, the pressing head 61 drives the connecting piece 7 and the limit block 3 to move, so that the limit block 3 retracts into the charging slot 11; at this time, the limit block 3 is disengaged from the limit on the battery, and the user can hold the battery to pull it out from the clamping block 4 and the battery connector 2, and remove the battery from the charging seat 1 to complete the charging of the battery.
