Detailed implementation manner

[0018] The present invention will be further described in detail below in conjunction with embodiments: Embodiment

[0019] As Figures 1-12 shown, the present invention provides a battery assembly for an electric medical device and an electric medical device, including a lithium battery 11. A heat dissipation sleeve 12 is fixedly connected to the surface of the lithium battery 11. A phase change material storage column 13 is arranged inside the heat dissipation sleeve 12. An insertion block 14 is fixedly connected to the surface of the heat dissipation sleeve 12. A slot 15 is opened on the surface of the heat dissipation sleeve 12. A mounting bracket 16 is fixedly connected to the end of the heat dissipation sleeve 12. A power supply contact 17 is fixedly connected inside the mounting bracket 16. One end of the power supply contact 17 is fixedly connected to a fuse 18. The other end of the fuse 18 is fixedly connected to the pole at the end of the lithium battery 11. An auxiliary battery bin mechanism is arranged inside the electric device. A main battery bin mechanism is arranged at the bottom of the electric device. A power supply conversion mechanism is arranged inside the electric device. The electric device includes a mounting shell 21. A drive motor 22 is fixedly connected inside the mounting shell 21. One end of the rotating shaft of the drive motor 22 is fixedly connected to a bone saw blade 23. A control button 24 for controlling the drive motor 22 is arranged on the surface of the mounting shell 21. A card slot 25 is opened on the surface at the lower end of the mounting shell 21.

[0020] In this embodiment, according to the size of the battery compartment of the electric medical device, the insertion block 14 in two adjacent battery units is inserted into the slot 15. After combining multiple battery units into a battery assembly, the battery assembly is then placed into the main battery compartment and the auxiliary battery compartment, so that the power supply contact 17 contacts the contact plate. The battery assembly is fixed in the main battery compartment and the auxiliary battery compartment through the first cover 33 and the second cover 43. Under the action of the first spring 432, the second contact plate 433 is pushed to abut against the other end of the battery assembly, improving the tightness of the connection between the power supply contact 17 and the contact plate, making the power supply of the battery assembly more stable. During the power supply process of the lithium battery 11, when the lithium battery 11 becomes overheated due to discharging, the phase change material in the phase change material storage column 13 is heated and melted, absorbing the heat generated during the discharging of the lithium battery 11, preventing the lithium battery 11 from overheating. When a single lithium battery 11 in the battery assembly fails, the fuse 18 is blown by an excessive current, cutting off the power supply of the faulty lithium battery 11, and the remaining lithium batteries 11 can continue to be used normally. During replacement, only the insertion block 14 needs to be pulled out of the slot 15 to remove the faulty lithium battery 11 for replacement, without replacing the entire battery assembly.

An installation frame 16 is fixedly connected to the end of the heat dissipation sleeve 12. A power supply contact 17 is fixedly connected inside the installation frame 16. One end of the power supply contact 17 is fixedly connected to a fuse 18. The other end of the fuse 18 is fixedly connected to the pole at the end of the lithium battery 11. A secondary battery compartment mechanism is arranged inside the electric appliance, a main battery compartment mechanism is arranged at the bottom of the electric appliance, and a power supply conversion mechanism is arranged inside the electric appliance. The electric appliance includes an installation shell 21. A drive motor 22 is fixedly connected inside the installation shell 21. One end of the shaft of the drive motor 22 is fixedly connected to a bone saw blade 23. A control button 24 for controlling the drive motor 22 is arranged on the surface of the installation shell 21. A card slot 25 is formed on the surface at the lower end of the installation shell 21. A connecting piece 47 is inserted into the inner wall of the insertion sleeve 44. One end of the connecting piece 47 is fixedly connected to a clamping block 48. The surface of the clamping block 48 abuts against the inner wall of the card slot 25. A third spring 49 is sleeved on the surface of the connecting piece 47. One end of the third spring 49 is fixedly connected to one side of the clamping block 48. The other end of the third spring 49 is fixedly connected to the inner wall of the insertion sleeve 44. The power supply conversion mechanism includes a power-on board 51. The bottom of the power-on board 51 abuts against the top of the connection contact plate 46. The top of the power-on board 51 is connected by a wire to a first power supply block 52 with an arc-shaped groove on its surface. A second power supply block 53 with an arc-shaped groove on its surface is arranged above the first power supply block 52. The second power supply block 53 is electrically connected to the first contact plate 32 through a wire. The inner wall of the arc-shaped groove on the surface of the first power supply block 52 abuts against a conversion contact block 54. The surface of the conversion contact block 54 is connected by a wire to a large capacitor 55. The large capacitor 55 is electrically connected to the control button 24 through a wire. One side of the conversion contact block 54 is fixedly connected to a telescopic rod 57. One end of the telescopic rod 57 is fixedly connected to a pushing block 56. The surface of the pushing block 56 is slidably connected to the inside of the installation shell 21. A fourth spring 58 is movably sleeved on the surface of the telescopic rod 57. One end of the fourth spring 58 is fixedly connected to one side of the conversion contact block 54. The other end of the fourth spring 58 is fixedly connected to the surface of the pushing block 56.

[0024] In this embodiment, during the power supply of the main battery compartment, the remaining power of the internal battery assembly is detected by the power detection terminal 42, and the remaining power is displayed through the display screen. When the remaining power is low, the push block 56 is pushed to slide within the installation shell 21, and the conversion contact block 54 is pushed to move. Under the action of the arc-shaped groove on the surface of the first power supply block 52, the conversion contact block 54 compresses the telescopic rod 57 and the fourth spring 58. When the conversion contact block 54 disengages from the first power supply block 52, the power stored in the large capacitor 55 supplies power to the drive motor 22 briefly. The push block 56 is continuously pushed until the conversion contact block 54 moves into the arc-shaped groove on the surface of the second power supply block 53. Under the reaction force of the fourth spring 58, the conversion contact block 54 is pushed to tightly abut against the second power supply block 53, enhancing the tightness of its connection. At this time, the battery assembly in the auxiliary battery compartment gradually takes over the load and charges the large capacitor 55, thus realizing seamless conversion between the main and auxiliary battery compartments. After switching to the auxiliary battery compartment for power supply, the assistant pulls the connecting member 47 to disengage the clamping block 48 from the clamping groove 25. At this time, the main battery compartment can be removed for replacement. After the replacement is completed, the push block 56 is dialed back to its original position to restore the power supply state of the main battery compartment, thereby improving the battery life and making it more convenient to use.

[0025] Next, specifically describe the battery assembly for the electric medical device and the working principle of the electric medical device.

[0026] Such as Figures 1-12As shown, during use, according to the size of the battery compartment of the electric medical device, the insertion block 14 in two adjacent battery units is inserted into the slot 15. After combining multiple battery units into a battery assembly, the battery assembly is then placed into the main battery compartment and the auxiliary battery compartment, so that the power supply contact 17 contacts the contact plate, and the battery assembly is fixed to the main battery compartment and the auxiliary battery compartment through the first cover 33 and the second cover 43. Under the action of the first spring 432, the second contact plate 433 is pushed to abut against the other end of the battery assembly, improving the tightness of the connection between the power supply contact 17 and the contact plate, making the power supply of the battery assembly more stable. Subsequently, the bottom of the installation shell 21 is inserted into the interior of the insertion sleeve 44. Under the action of the contact between the bottom of the installation shell 21 and the arc surface of the latch 48, the latch 48 pushes the connecting member 47 to move outward and compresses the third spring 49. At the same time, the power-on plate 51 contacts the top of the connecting contact plate 46, pushing the connecting contact plate 46 downward and compressing the second spring 45. Under the thrust of the reaction force of the second spring 45, the connecting contact plate 46 contacts the power-on plate 51 more tightly. When the card slot 25 moves to one side of the latch 48, under the elastic force of the third spring 49, the latch 48 enters the card slot 25, thereby installing the main battery compartment at the bottom of the electric device. The main battery compartment outputs current through the connecting contact plate 46, enters the conversion contact block 54 in contact with the first power supply block 52 through the power-on plate 51, and then enters the large capacitor 55 under the guidance of the wire, and supplies power to the drive motor 22 through the control button 24. During use, hold the electric device and press the control button 24 to control the start of the drive motor 22, and drive the rotation of the bone saw blade 23 through the drive motor 22 for surgical treatment. During the power supply of the lithium battery 11, when the lithium battery 11 becomes too hot due to discharge, the phase change material in the phase change material storage column 13 melts when heated, absorbing the heat generated during the discharge of the lithium battery 11 to prevent the lithium battery 11 from overheating. When a single lithium battery 11 in the battery assembly fails, the fuse 18 is blown by an excessive current, cutting off the power supply of the faulty lithium battery 11, and the remaining lithium batteries 11 can continue to be used normally. During replacement, only need to pull out the insertion block 14 from the slot 15 to remove the faulty lithium battery 11 for replacement, without replacing the entire battery assembly. During the power supply of the main battery compartment, the remaining power of the internal battery assembly is detected by the power detection terminal 42 and the remaining power is displayed through the display screen. When the remaining power is less, push the push block 56 to make it slide in the installation shell 21 and push the conversion contact block 54 to move. Under the action of the arc-shaped groove on the surface of the first power supply block 52, the conversion contact block 54 compresses the telescopic rod 57 and the fourth spring 58. When the conversion contact block 54 disengages from the first power supply block 52, the power stored in the large capacitor 55 supplies power to the drive motor 22 for a short time. Continue to push the push block 56 until the conversion contact block 54 moves into the arc-shaped groove on the surface of the second power supply block 53. Under the reaction force of the fourth spring 58, the conversion contact block 54 is pushed to tightly abut against the second power supply block 53, enhancing the tightness of its connection.At this time, the battery module in the auxiliary battery compartment gradually takes over the load and charges the large capacitor 55, thus realizing seamless switching between the main and auxiliary battery compartments. After switching to the auxiliary battery compartment for power supply, the assistant pulls the connecting member 47 to disengage the latch 48 from the card slot 25. At this time, the main battery compartment can be removed for replacement. After the replacement is completed, the push block 56 is pushed back to its original position to restore the power supply state of the main battery compartment, thereby improving the battery life and making it more convenient to use.

[0027] The present invention has been generally and exhaustively described above. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, any modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
