[0018] In this embodiment, unless otherwise specified, all methods used are conventional methods.

[0019] Example: See Figures 2 to 5 This embodiment provides a novel quick-release battery device 1 for an instrument. The device includes a device body 11, a battery pack 12, and a first PCBA board 13. The battery pack 12 is electrically connected to the first PCBA board 13 and is both internally disposed in the device body 11. An electrode needle mounting base 111 is provided extending outward from the device body 11; The first PCBA board 13 is electrically connected to several sets of battery electrode pins 14, which are disposed in the electrode pin mounting base 111 to meet both power supply and creepage requirements. Both ends of the device body 11 are provided with elastic disassembly and assembly mechanisms. The elastic disassembly and assembly mechanisms have a first state in which the device is elastically compressed to detach from the instrument, and a second state in which the device is elastically released to install the device onto the instrument.

[0020] Preferably, the elastic disassembly mechanism includes an elastic disassembly base and a buckle 15. The buckle 15 is elastically installed in the elastic disassembly base by a spring 16. That is, by pressing or releasing the buckle 15, under the deformation or reset action of the spring 16, the buckle 15 moves laterally in the elastic disassembly base to achieve disassembly or installation. The end of the elastic mounting base away from the device body 11 is provided with a pressing hole, which is adapted to the buckle 15 to enable pressing or releasing the buckle 15; When the buckle 15 is pressed, it causes the spring 16 to deform under pressure, triggering the first state. When the buckle 15 is released, it causes the spring 16 to reset, triggering the second state.

[0021] Furthermore, the buckle 15 includes an integrally formed pressing end and a locking end. The pressing end abuts against the spring 16 and is adapted to be disposed in the pressing hole. The pressing direction of the pressing end is parallel to the compression direction of the spring 16. The locking end extends from the elastic mounting base to realize installation on the instrument.

[0022] Specifically, when the buckle 15 is in the first state, that is, when the pressing end is pressed through the pressing hole, the spring 16 is compressed and deformed, causing the locking end to detach from the instrument, thereby realizing the disassembly of the new instrument quick-release battery device. When the buckle 15 is in the second state, the pressing end approaches the pressing hole under the reset action of the spring 16. At this time, the locking end also approaches the slot of the instrument, realizing the installation of the new instrument quick-release battery device.

[0023] Preferably, the battery pack 12 includes a battery compartment, a battery cover, and a battery string disposed within the battery compartment. The battery cover is detachably mounted on the battery compartment. The battery string is formed by connecting several groups of batteries 121 end to end with positive and negative terminals connected in series. The beginning and end of the battery string are electrically connected to the first PCBA board 13 via connectors 17. Specifically, the battery compartment is movably installed and removed from the device body 11. When the cover of the body is removed, the battery compartment can be taken out according to the actual use, and then the battery cover can be opened to replace the battery string. The beginning and end of the battery string are electrically connected to the connectors 17 via positive and negative terminals, respectively.

[0024] Preferably, the battery string includes several battery packs arranged in series and stacked, and adjacent battery packs are electrically connected by vertical positive and negative electrode plates 122. Each of the battery packs includes several groups of batteries 121 connected in series with their positive and negative electrodes connected end to end. Adjacent batteries 121 are electrically connected by horizontal positive and negative electrode plates 123.

[0025] Preferably, a horizontal isolation plate is provided between adjacent battery packs, and a vertical isolation plate is provided between adjacent batteries 121, which effectively improves the installation stability and anti-cross-current performance between batteries 121. The device body 11 also includes an upper body cover and a lower body cover that are assembled and disposed thereon. The electrode needle mounting base 111 is formed by extending outward from the lower body cover. The elastic disassembly and assembly mechanisms are all disposed at both ends of the upper body cover. The creepage path is formed sequentially along the horizontal isolation plate, the vertical isolation plate, the battery compartment and the top cover of the main body, which effectively increases the creepage distance and meets the creepage distance and electrical clearance requirements from the battery 121 to the outside of the device body 11.

[0026] See Figures 1 to 2 This embodiment also discloses an instrument, which includes the novel instrument quick-release battery device 1 described above.

[0027] Preferably, the instrument further includes a second PCB board 21, which is electrically connected to a plurality of spring pins 22 for electrical connection with the battery electrode pins 14. The number of spring pins 22 is equal to the number of battery electrode pins 14. Specifically, when the new instrument quick-release battery device is installed in the instrument, the spring pins 22 contact the battery electrode pins 14 to achieve electrical connection, thereby meeting the power supply requirements of the instrument.

[0028] Preferably, the instrument further includes a slot adapted to the elastic disassembly mechanism to enable the novel quick-release battery device to be installed or detached from the instrument; specifically, when the novel quick-release battery device is installed in the instrument, the locking end of the buckle 15 is engaged in the slot to enable the installation of the novel quick-release battery device.

[0029] Furthermore, a pressing clearance groove is provided on the instrument corresponding to the elastic disassembly mechanism, so that the operator can make clearance when pressing the elastic disassembly mechanism.

[0030] The assembly and installation of the new instrument quick-release battery device includes the following steps: Step 1: Install the first PCBA board 13 into the lower cover of the main body, wherein the battery electrode needle 14 is installed in the electrode needle mounting base 111; Step 2: Install the spring 16 and the buckle 15 into the elastic mounting base, wherein the pressing end is positioned in the pressing hole under the elastic action of the spring 16, and the locking end extends out from the elastic mounting base; Step 3: Install several sets of batteries 121 in the battery compartment, wherein the positive and negative terminals of the several sets of batteries 121 are connected in series to form a battery string. Step 4: Place the battery compartment in the upper cover of the main body and connect the connector 17 to the first PCBA board 13 to achieve electrical connection between the battery string and the first PCBA board 13. Step 5: Assemble the lower cover of the main body onto the upper cover of the main body and secure it with screws, then assemble the battery cover to complete the assembly of the new instrument quick-release battery device. Step 6: Press the assembled new instrument quick-release battery device into the instrument. At this time, the battery electrode needle 14 is in contact with the spring needle 22 to realize the electrical connection between the battery string and the second PCBA board 21. When the pressing end is pressed, the spring 16 is deformed by pressure, and the locking end enters the slot. After the new instrument quick-release battery device is placed in place, the pressing end is released, and under the reset action of the spring 16, the locking end is locked in the slot, thereby realizing the installation of the new instrument quick-release battery device.
