Description

Technical Field

[0001] The utility model relates to a battery, in particular to a positive and negative electrode same-direction mounting structure, a battery and an electrical device. Background Art

[0002] With the invention of electricity, human society entered the era of electrification. Currently, an increasing number of devices are becoming intelligent and electronic, and batteries are the energy source for these devices. Current cylindrical steel-cased batteries have oppositely oriented positive and negative poles, while capacitive batteries have the same orientation. However, due to their structural characteristics, capacitive batteries are less safe than polymer batteries and steel-cased batteries, limiting their application.

[0003] Batteries with positive and negative poles in the same direction are convenient for the production and assembly of electronic products and the individual disassembly of batteries. With the introduction of the European Battery Act, they will be used more and more in the future (traditional batteries with positive and negative poles in different directions, corresponding to the battery compartments of electronic products, require separate electrical connectors to be connected to both ends of the battery, such as the battery compartments of remote controls, flashlights and mice).

[0004] The traditional method of converting polymer batteries to have the positive and negative electrodes in the same direction is to achieve this goal by welding them to the wires. The welding process has the following main disadvantages:

[0005] 1. The current welding process is prone to forming false welds when welding batteries, causing battery failure.

[0006] 2. When current batteries are welded using a welding process, the high temperature of welding can easily damage the battery structure, causing damage to the battery, resulting in bulging, flatulence, short circuit and fire.

[0007] 3. When the current battery adopts welding technology, the consistency of the welding points is difficult to control, resulting in poor consistency of the internal resistance of the battery.

[0008] 4. When the current battery adopts welding technology, manual welding is required, which has low welding efficiency. In addition, some of the gases generated during welding are harmful and will harm the health of employees. In addition, the proficiency of welders is different, and the consistency of products is difficult to control.

[0009] 5. Current batteries are soldered with tin, which is a precious metal with limited reserves. Utility Model Content

[0010] The purpose of the present utility model is to overcome the above-mentioned problems and provide a positive and negative electrode same-direction installation structure, which can realize the same-direction layout of positive and negative electrodes without welding, which can not only protect the battery structure, but also improve the stability and consistency of the product.

[0011] Another object of the present invention is to provide a battery and an electrical device.

[0012] The purpose of the utility model is achieved through the following technical solutions:

[0013] A positive and negative electrode same-direction installation structure, comprising a positive and negative electrode same-direction plate, an intermediate conductive block and an electrode lead-out piece;

[0014] The intermediate conductive block is fixedly arranged on one side of the positive and negative electrode same-direction plates and is electrically connected to the positive and negative electrode same-direction plates;

[0015] The electrode lead-out member is electrically connected to the positive electrode and / or the negative electrode of the battery cell. The electrode lead-out member is in direct contact with the intermediate conductive block in a non-fixed manner to form electrical conduction.

[0016] In a preferred embodiment of the present invention, an elastic support structure for promoting the electrode lead-out member to fit with the middle conductive block is provided below the electrode lead-out member.

[0017] Furthermore, the elastic support structure is an elastic gasket or spring with protrusions.

[0018] Furthermore, the elastic supporting structure is an elastic insulating layer formed after the liquid material solidifies.

[0019] Through the above structure, an adaptive elastic force can be applied to the electrode lead-out piece, so that the electrode lead-out piece and the intermediate conductive block are in stable contact, which can effectively solve the problem of unstable contact between the positive and negative poles of the battery and the positive and negative poles of the plate, and can effectively increase the contact area between the two and improve the consistency of the product.

[0020] In a preferred embodiment of the present invention, a first lead-out electrode and a second lead-out electrode are provided on the other side of the positive and negative electrode plates in the same direction, and the outermost ends of the first lead-out electrode and the second lead-out electrode are located at different heights, which can prevent short circuit.

[0021] A battery comprises a shell, a battery cell arranged in the shell, and a positive and negative electrode same-direction mounting structure.

[0022] In a preferred embodiment of the present invention, the positive and negative electrodes in the same direction are fixedly connected to the inner cavity wall of the shell through an adhesive.

[0023] In a preferred embodiment of the present invention, the housing is provided with a stopper protruding from the inner wall; the positive and negative electrode alignment plates are located between the stopper and the battery cell. This allows the positive and negative electrode alignment plates and the intermediate conductive block to be secured within the housing, allowing the intermediate conductive block to directly contact the electrode lead-out member.

[0024] A preferred embodiment of the present invention is that the positive and negative electrodes of the battery cell are respectively connected to different electrode lead-out pieces, wherein the electrode lead-out piece connected to the positive electrode of the battery cell is longer and goes around from the positive electrode side of the battery cell to the negative electrode side of the battery cell.

[0025] Furthermore, two intermediate conductive blocks are provided and are directly connected to the two electrode lead-out pieces respectively.

[0026] Furthermore, the thicknesses of the two middle conductive blocks are different.

[0027] In a preferred embodiment of the present invention, the inner cavity of the housing includes a mounting cavity for mounting the positive and negative electrode plates. The diameter of this mounting cavity is larger than the diameter of the inner cavity body, and the mounting cavity is provided with a retaining groove surface to limit the position of the positive and negative electrode plates. This structure allows the positive and negative electrode plates to be precisely mounted in position, using the retaining groove surface as a reference, ensuring close contact between the intermediate conductive block and the electrode lead-out member without excessively squeezing the battery cell, thus protecting the battery cell structure.

[0028] In a preferred embodiment of the present invention, a plurality of disassembly notches are provided on the shell at positions corresponding to the positive and negative electrode plates in the same direction. The positive and negative electrode plates in the same direction can be pried open with a crowbar to recycle the battery cells.

[0029] An electrical device comprises the battery, and the battery is used to provide electrical energy.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The positive and negative electrodes in the same direction installation structure of the present invention are installed in the same direction by setting an intermediate conductive block between the positive electrode or the negative electrode of the battery cell of the positive and negative electrode same direction plate battery, and directly contacting the intermediate conductive block with the positive electrode or the negative electrode of the battery cell. This can achieve the same direction layout of the positive and negative electrodes without welding, which can not only protect the battery structure, but also improve the stability and consistency of the product.

[0032] 2. Since there is no need for welding, the electrodes and batteries can be made into standard parts and then crimped, which can stably improve the consistency of the products and increase production efficiency.

[0033] 3. By placing the positive and negative plates in different planes, the fire caused by the short circuit between the positive and negative poles of the battery can be effectively solved.

[0034] 4. By converting the electrodes to different thicknesses after the same measurement, it is possible to effectively avoid the same intermediate conductive block of the positive and negative plates in the same direction from contacting both electrodes at the same time during production, causing a short circuit and fire in the battery. It can also ensure better contact between the battery cell electrodes and the intermediate conductive block.

[0035] 5. By setting the intermediate conductive blocks of the positive and negative plates in the same direction to different thicknesses, it is possible to effectively avoid the same intermediate conductive block of the positive and negative plates in the same direction from contacting both electrodes at the same time during production, causing a short circuit and fire in the battery. It can also allow the intermediate conductive block to better contact with the battery cell electrodes.

[0036] 6. Place the battery upside down (positive pole at the bottom, negative pole at the top). The type-C shell of the charging port can be made into the negative pole, and the shell can be used to directly contact the negative pole of the battery, eliminating the need for an insulating layer between the positive and negative poles of the battery and the PCB board in the traditional design.

[0037] 7. Place a layer of elastic supporting insulating material on the side of the battery close to the positive and negative poles in the same direction. The insulating material plays a role of fixing and insulating, which can effectively prevent the positive and negative poles of the battery from contacting, and prevent the negative pole of the battery from contacting the aluminum-plastic film of the battery cell, and fix the positive and negative pole positions of the battery to prevent the battery and PCB board from being misaligned during assembly.

[0041] Figure 4 It is a cross-sectional view of another embodiment of the battery of the present invention. DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0043] Example 1

[0044] See also Figure 1-3 The electrical device of this embodiment includes a battery for providing electrical energy. The battery includes a shell 1, a battery cell 2 arranged in the shell 1, and a positive and negative electrode same-direction installation structure.

[0045] The positive and negative electrode same-direction installation structure includes a positive and negative electrode same-direction plate 3 (which can be a PCB board, etc.), an intermediate conductive block 4 and an electrode lead-out piece 5; the intermediate conductive block 4 is fixedly arranged on the positive and negative electrode same-direction plate 3 and is electrically connected to the positive and negative electrode same-direction plate 3; there are two intermediate conductive blocks 4; there are two electrode lead-out pieces 5 and they are in direct contact with the two intermediate conductive blocks 4 respectively to form electrical conduction; the positive and negative poles of the battery cell 2 are respectively connected to different electrode lead-out pieces 5, wherein the electrode lead-out piece 5 connected to the positive pole of the battery cell 2 is longer and goes around from the positive pole side of the battery cell 2 to the negative pole side of the battery cell 2.

[0046] Specifically, when equipped with a charging port, since the shell 1 of the TYPEC charging port is the negative pole, the battery must be placed upside down in the shell 1, with the positive pole of the battery at the bottom of the shell 1 and the negative pole at the head of the shell 1 (the side away from the positive and negative poles is the bottom, and the side close to them is the head).

[0047] Furthermore, the thicknesses of the two middle conductive blocks 4 are different.

[0048] See also Figure 1-3 An elastic support structure 6 is provided below the electrode lead-out member 5 to facilitate the electrode lead-out member 5 to fit with the intermediate conductive block 4 .

[0049] Furthermore, the elastic supporting structure 6 is an elastic gasket or spring with protrusions.

[0050] Furthermore, the elastic support structure 6 is an elastic insulating layer formed after the liquid material solidifies. The specific operation is to inject the liquid material into the end of the battery, use the solid-liquid reaction in the chemistry to directly generate the elastic insulating layer, and bend the electrode lead-out piece 5 after the battery solidifies.

[0051] Through the above structure, an adaptive elastic force can be applied to the electrode lead-out member 5, so that the electrode lead-out member 5 and the intermediate conductive block 4 are in stable contact, which can effectively solve the problem of unstable contact between the positive and negative poles of the battery and the positive and negative poles of the plate, and can effectively increase the contact area between the two to improve the consistency of the product.

[0052] See also Figure 1 A first lead-out electrode 3-1 and a second lead-out electrode 3-2 are provided on the other side of the positive and negative electrode same-direction plate 3. The outermost ends of the first lead-out electrode 3-1 and the second lead-out electrode 3-2 are located at different heights, which can prevent short circuit.

[0053] See also Figure 1-3 The positive and negative electrode plates 3 are fixedly connected to the inner wall of the housing 1 by adhesive. In this way, the positive and negative electrode plates 3 and the intermediate conductive block 4 can be fixed in the housing 1, and the intermediate conductive block 4 is in direct contact with the electrode lead-out member 5.

[0054] See also Figure 1-3 The inner cavity of the housing 1 includes a mounting cavity for mounting the positive and negative electrode directional plates 3. The diameter of this mounting cavity is larger than the diameter of the inner cavity body, and a retaining groove surface is provided in this mounting cavity to limit the position of the positive and negative electrode directional plates 3. Through this structure, the retaining groove surface serves as a reference, and the positive and negative electrode directional plates 3 can be precisely installed in position, ensuring close contact between the intermediate conductive block 4 and the electrode lead-out member 5 without excessively squeezing the battery cell 2, thereby protecting the battery cell 2 structure.

[0055] See also Figure 1-2 The shell 1 is provided with a plurality of disassembly notches 1-2 at positions corresponding to the positive and negative electrode plates 3. The positive and negative electrode plates 3 can be pried open with a crowbar to recycle the battery cells 2.

[0056] Example 2

[0057] See also Figure 4 Unlike Example 1, this embodiment features a stopper 1-1 protruding from the inner wall of the housing 1; the positive and negative electrode directional plates 3 are located between the stopper 1-1 and the battery cells 2. After the battery cells 2 and the positive and negative electrode directional plates 3 are placed within the housing 1, the outer wall of the housing 1 near the opening is rolled to form a recessed portion (stopper 1-1). The mechanical force of the stopper 1-1 then presses the positive and negative electrode directional plates 3 with the intermediate conductive blocks 4 together with the battery's electrode lead-out members 5.

[0058] Example 3

[0059] Different from Example 1, in addition to the positive and negative ends in the same direction (this end face is responsible for electrical connection with the electronic device used), the shell of this embodiment is provided with a PCBA charging module end at the other end of the battery (this end face is responsible for charging the battery). Two intermediate conductive blocks of different thicknesses are provided on the side of the positive and negative ends in the same direction that contacts the battery, which are responsible for connecting to the electrode lead-out pieces corresponding to the two electrodes of the battery. The two intermediate conductive blocks of different thicknesses on the other side of the PCBA charging module are responsible for connecting to the electrode lead-out pieces corresponding to the two electrodes of the battery. (Since the output end does not pass through the PCBA, this setting can only provide charging protection for the battery)

[0060] Example 4

[0061] Unlike Example 1, two intermediate conductive blocks of different thicknesses are installed on the side where the positive and negative terminals in the same direction contact the battery. The first intermediate conductive block is responsible for connecting to the battery's electrode lead-out piece, and the second intermediate conductive block is connected to the electrode lead-out piece of the PCBA. (Because the output terminal passes through the PCBA, this arrangement can protect the battery both during charging and discharging.)

[0062] Example 5

[0063] Different from Example 1, the shell of the TYPEC charging port in the PCBA charging module is a negative electrode intermediate conductive block, which is connected to one pole of the battery.

[0064] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
