Of course, the drawings described below are merely embodiments of the present invention, and those skilled in the art can think of other drawings based on the drawings provided without any creative effort.

[0025] The present invention will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method or functional transformations made by those skilled in the art based on these embodiments are within the protection scope of the present invention.

[0026] In each of the drawings of the present invention, for convenience of illustration, the dimensions of some of the structures or parts are exaggerated relative to other structures or parts, and these are merely for illustrating the basic structure of the subject matter of the present invention.

[0027] 1 to 5, a battery assembly 100 of the present invention includes a battery pack 1 and a plurality of connection pieces 2 electrically connected to the battery pack 1. The electrical connection can be achieved by welding or a conductive adhesive.

[0028] The battery pack 1 includes at least two series-connected batteries 11. Preferably, at least two batteries 11 are stacked, and the number of the batteries 11 can be adjusted according to a desired output voltage.

[0029] In one embodiment, the battery 11 is a button-type silver oxide battery, which has a small volume and can meet the security requirements of the medical capsule 200 in terms of safety and stability.

[0030] The multiple connection pieces 2 include a positive electrode connection piece 21 electrically connected to the positive electrode 111 of the battery pack 1, a negative electrode connection piece 22 electrically connected to the negative electrode 112 of the battery pack 1, and an intermediate connection piece 23 electrically connected to both the positive electrode 111 of one of any two adjacent batteries 11 and the negative electrode 112 of the other. Therefore, the total voltage of the battery pack 1 can be output by the positive electrode connection piece 21 and the negative electrode connection piece 22, and a partial voltage of the battery pack 1 can be output by cooperation between one of the positive electrode or the negative electrode and the intermediate connection piece 23, thereby realizing the supply of power to different electric elements, or the supply of different voltages to the same electric element as necessary.

[0031] "Outputting a voltage of a part of the assembled battery 1" means that the assembled battery 1 includes at least two batteries 11 connected in series, and outputs the voltage of N of the batteries 11 through cooperation between one of the positive electrode or the negative electrode and the intermediate connector 23, where N is an integer equal to or less than the total number of batteries 11 included in the assembled battery 1. For example, when the assembled battery 1 includes two batteries 11 connected in series, it can output the voltage of one battery 11.

[0032] The number of batteries 11 connected in series between the intermediate connection piece 23 and the positive electrode connection piece 21 and the number of batteries 11 connected in series between the intermediate connection piece 23 and the negative electrode connection piece 22 can both be adjusted according to the desired output voltage. For example, when one battery 11 is connected in series between the intermediate connection piece 23 and the positive electrode connection piece 21, or when one battery 11 is connected in series between the intermediate connection piece 23 and the negative electrode connection piece 22, the voltage of a single battery 11 can be output.

[0033] The connection piece 2 further includes a welded portion 24 that is welded to the battery 11, and an output portion 25 that is connected to the welded portion 24. Usually, the welded portion 24 and the output portion 25 are integrally provided, and the output portion 25 can be bent into a desired shape so as to be easily mounted inside the medical capsule 200. The connection piece 2 here includes the positive electrode connection piece 21, the negative electrode connection piece 22, and the intermediate connection piece 23.

[0034] 1, 2 and 3, the positive electrode connection piece 21 and the negative electrode connection piece 22 have a similar structure, and their welded parts 24 are circular to facilitate multi-point welding with the battery pack 1 and improve the stability of the welding. The welded parts 24 include a plurality of welded points, for example, the welded parts 24 include at least four welded points, and are welded by soldering, high-pressure spot welding or laser spot welding, which can improve the stability of the power supply. The output parts 251, 252 are rod-shaped and easily bendable.

[0035] In the preferred solution, the connection between the connecting piece 2 and the electrode of the battery 11 is made by spot welding, and laser spot welding is preferred due to its high consistency and high degree of automation. Soldering is used between the connecting piece 2 and a PCB (Printed Circuit Board) or a load electric element to maintain the stability of the welding.

[0036] As shown in FIGS. 1 and 4, the intermediate connection piece 23 has a rod shape as a whole, and after its welded parts are welded to two adjacent batteries 11, it is laminated between the two batteries 11.

[0037] Furthermore, the connection piece 2 is a nickel-plated SPCC (Cold Rolled Steel, general-purpose cold rolled steel plate and strip), nickel piece, or copper piece, which can be welded to the electrodes of the battery 11, the PCB board, and the load electric element. A pure nickel piece is preferred because it can effectively avoid soldering defects. The pure nickel piece is formed from pure nickel, which is generally referred to in the industry, and does not only refer to pure nickel with a nickel content of 100%, but may contain a trace amount of impurities that cannot be eliminated in the refining process.

[0038] The output portion 251 of the positive electrode connection piece 21 and the output portion 252 of the negative electrode connection piece 22 extend toward the side of the battery pack 1 where the positive electrode 111 or the negative electrode 112 is located, and are welded to the same PCB board. The output portion 253 of the intermediate connection piece 23 extends toward the other side of the battery pack 1. The output portion 253 of the intermediate connection piece 23 is connected to a certain load electric element, and can output a partial voltage of the entire battery pack 1 to the load electric element in cooperation with the PCB board.

[0039] 1 to 5, in one specific embodiment, the output portion 251 of the positive electrode connection piece 21 and the output portion 252 of the negative electrode connection piece 22 both extend toward the side where the positive electrode 111 of the battery pack 1 is located, and are welded to a PCB board. The output portion 253 of the intermediate connection piece 23 extends toward the side where the negative electrode 112 of the battery pack 1 is located.

[0040] Based on any of the above embodiments, the battery assembly 100 further includes an insulating assembly 3, and a person skilled in the art can understand that the insulating assembly 3 is provided between two components that need to be insulated to avoid short circuit. For example, the insulating assembly 3 is provided between adjacent batteries 11, or between the connection piece 2 and the battery 11, or between the battery 11 and the connecting piece 2. Battery pack 1and an adjacent PCB board, or between the battery assembly 100 and another adjacent electrical element.

[0041] Specifically, the insulating assembly 3 includes an annular insulating gasket 31 located around the negative electrode 112 of the battery 11, and the insulating gasket 31 is attached to the negative electrode 112 of the battery 11 so as to just cover the positive electrode portion around the negative electrode 112 of the battery 11, in order to avoid short-circuiting of the positive electrode region and the negative electrode region of the battery 11 by a device or other electrical contact. For example, the negative electrode 112 and the positive electrode portion around the negative electrode 112 can be isolated, or the connection piece 2 connected to the negative electrode 112 and the positive electrode portion around the negative electrode 112 can be isolated.

[0042] The insulating gasket 31 is a thin film made of adhesive-attached PET (polyethylene terephthalate), PVC (polyvinyl chloride), PP (polypropylene), or PA (polyamide) material. The thickness of the insulating gasket 31 is 0.01 mm to 0.5 mm, preferably 0.05 mm to 0.15 mm, which can achieve both good processing yield and excellent insulating properties.

[0043] As shown in Figs. 1 to 5, the output portion 251 of the positive electrode connection piece 21 and the output portion 252 of the negative electrode connection piece 22 both extend toward the side where the positive electrode 111 of the battery pack 1 is located, and the output portion 253 of the intermediate connection piece 23 extends toward the side where the negative electrode 112 of the battery pack 1 is located. Insulation is required between the negative electrode connection piece 22 and the side wall of the battery pack 1. The insulating assembly 3 further includes a first insulating piece 32 that is located on the side of the output portion 252 of the negative electrode connection piece 22 facing the battery 11 and insulates between the negative electrode connection piece 22 and the side wall of the battery pack 1. Preferably, the first insulating piece 32 is bent and extends to the side of the positive electrode connection piece 21 that is away from the battery pack 1, insulating and dividing the entire battery assembly 100 and the PCB board.

[0044] In this embodiment, if there is only one battery 11 between the welded portion of the intermediate connection piece 23 and the negative electrode 112 of the assembled battery 1, there is no need for insulation between the output portion 253 of the intermediate connection piece 23 and the side wall of the battery 11, and therefore an insulating piece may or may not be provided on the side of the output portion 253 of the intermediate connection piece 23 facing the battery 11. If there are at least two batteries 11 between the welded portion of the intermediate connection piece 23 and the negative electrode 112 of the assembled battery 1, it is necessary to provide an insulating piece on the side of the output portion 253 of the intermediate connection piece 23 facing the battery 11 in order to prevent the occurrence of a short circuit.

[0045] Alternatively, the output portion 251 of the positive electrode connection piece 21 and the output portion 252 of the negative electrode connection piece 22 both extend toward the side where the negative electrode 112 of the battery pack 1 is located, the output portion 253 of the intermediate connection piece 23 extends toward the side where the positive electrode 111 of the battery pack 1 is located, and the insulating assembly 3 further includes a second insulating piece located on the side of the output portion 251 of the positive electrode connection piece 21 facing the battery 11, and a third insulating piece located on the side of the output portion 253 of the intermediate connection piece 23 facing the battery 11.

[0046] The battery assembly 100 of the present invention can be used in a variety of medical capsules 200, including but not limited to vibratory capsules, endoscopy capsules, and the like.

[0047] 6 , the medical capsule 200 is a vibration capsule, and includes a shell 4, a vibration source 5 located in the shell 4, the battery assembly 100, and a control unit 6. The vibration source 5, the battery assembly 100, and the control unit 6 are fixed in the shell 4 by a fixing structure 7.

[0048] The shell 4 and the vibration source 5 are both made of any of the conventional technologies, and the battery assembly 100 is any of the above.

[0049] The control unit 6 includes a PCB board 61 and a reed switch 62 communicatively connected on the PCB board 61, the positive electrode connection piece 21 and the negative electrode connection piece 22 are both electrically connected to the PCB board 61, and the vibration source 5 is electrically connected to both the PCB board 61 and the intermediate connection piece 23, and therefore can output different voltages within the allowable voltage range of the vibration source 5.

[0050] As described above, the battery assembly 100 of the present invention can output the total voltage of the assembled battery 1 by the positive electrode connection piece 21 and the negative electrode connection piece 22, and can also output a portion of the voltage of the assembled battery 1 by cooperation between one of the positive electrode or the negative electrode and the intermediate connection piece 23. This makes it possible to supply power to different electric elements, or supply different voltages to the same electric element as necessary.

Those skilled in the art should take the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
