Description

Technical Field

[0001] The present invention relates to the technical field of battery components, and in particular to a battery and an electronic device. Background Art

[0002] With the continuous development of electronic devices, compact portable electronic devices such as portable smart phones or watch-type mobile terminals have gradually emerged, and the power source of the portable electronic terminal is an indispensable part.

[0003] Currently, most portable electronic devices need to be worn on the user's body. For example, some portable electronic devices need to be worn on the wrist. Most of the existing portable electronic devices worn on the wrist use the method of a wristband, and the battery of the portable electronic device is installed in the main body part.

[0004] However, the volume of such portable electronic devices is generally large, and there is an urgent hope in the industry for a completely flexible portable electronic device, such as a wristband-type portable electronic device, which can be worn on the user's body without the need to separately configure a wristband, and the portable electronic device also has a smaller volume of the main body part. Summary of the Invention

[0005] The present invention provides a battery and an electronic device, which can effectively solve the above or other potential technical problems.

[0006] The first aspect of the present invention is to provide a battery, which includes connection pieces and a plurality of battery units; the connection pieces are provided with a plurality of installation positions and connection segments connecting adjacent installation positions at intervals in a first direction, and the battery units are correspondingly arranged in the installation positions; the battery unit includes a housing and a battery core element accommodated in the housing; the housing of the battery unit is connected to the connection piece.

[0007] In an optional embodiment according to the first aspect, the connection piece forms a plurality of bending parts at intervals in the first direction, and an installation position is formed between two adjacent bending parts. It should be noted that by forming a plurality of bending parts at intervals along the length direction of the connection piece, an installation position is formed between two adjacent bending parts, that is, in this way, the method of forming the installation position is simple and easy to operate. At the same time, the bending parts can be used as intervals to separate two battery units, and due to the structural characteristics of the bending parts, they have a certain ductility, which can help the entire connection piece to be bent.

[0008] In an alternative embodiment according to the first aspect, the highest point of the top end of the bent portion is not higher than the top surface of the battery cell disposed within the mounting position. It should be noted that making the highest point of the top end of the bent portion not higher than the top surface of the battery cell disposed within the mounting position facilitates separating adjacent battery cells to form the mounting position, while saving the material of the connecting piece, thereby saving costs and reducing the overall weight of the battery assembly, making it easier to achieve a lightweight product.

[0009] In an alternative embodiment according to the first aspect, the width of the bent portion is 0.5 mm - 5 mm.

[0010] In an alternative embodiment according to the first aspect, the material of the connecting piece is at least one of stainless steel, nickel-cobalt-iron alloy, manganese-nickel-copper alloy, or nickel-chromium-iron alloy. It should be noted that stainless steel, nickel-cobalt-iron alloy, manganese-nickel-copper alloy, or nickel-chromium-iron alloy are all bendable materials with good electrical conductivity. Using the above materials to make the connecting piece can ensure the electrical conductivity and bending function of the connecting piece.

[0011] In an alternative embodiment according to the first aspect, the battery cells are electrically connected in series or in parallel through the connecting piece.

[0012] In an alternative embodiment according to the first aspect, the housing is composed of a top shell, side walls, and a mounting position. One end of the side wall is connected to the top shell, and the other end is connected to the mounting position to form a receiving cavity for accommodating the battery cell components. It should be noted that in this embodiment, the housing is composed of a top shell, side walls, and a mounting position, that is, the mounting position is used as the bottom wall of the housing, and together with the top shell and side walls, it forms a receiving cavity for accommodating the battery cell components. Such a setting can directly utilize the material of the mounting position. Compared with a complete housing, when the entire housing is installed in the mounting position, the setting method in the present application saves more materials and reduces the overall weight of the battery.

[0013] In an alternative embodiment according to the first aspect, the housing is composed of a top shell, side walls, and a bottom shell. One end of the side wall is connected to the top shell, and the other end is connected to the bottom shell to form a receiving cavity for accommodating the battery cell components; the bottom shell is connected to the connecting piece. It should be noted that when the housing is directly set to include a top shell, side walls, and a bottom shell, with one end of the side wall connected to the top shell and the other end connected to the bottom shell to form a receiving cavity for accommodating the battery cell components, it is convenient to independently install the battery cell in the mounting position. When one of the battery cells fails, it is convenient to remove the battery cell for replacement. Compared with the above situation where the mounting position is used as the bottom wall of the housing, this setting method facilitates the replacement and repair of the battery cell. And since the overall structure of the battery cell is already stably sealed, there is no need to assemble on the connecting piece, so the overall structure is more stable, more convenient to use, and makes the overall assembly process of the battery simpler and easier to operate, improving the assembly efficiency.

[0014] In an alternative embodiment according to the first aspect, the connecting piece is provided with a plurality of through holes. It should be noted that providing a plurality of through holes in the connecting piece facilitates making it in a hollow shape, which is conducive to cooling the battery unit. At the same time, setting a plurality of through holes in the connecting piece can effectively reduce the weight of the connecting piece, facilitate the realization of the overall lightness of the battery, and further achieve material saving and cost reduction.

[0015] In an alternative embodiment according to the first aspect, the cell component includes a cell body, a positive tab and a negative tab provided on the cell body; the negative tab is provided on the bottom case and is electrically connected to the mounting position. At the same time, in this application, the cell component includes a cell body, a positive tab and a negative tab provided on the cell body; the negative tab is provided on the bottom case and is electrically connected to the mounting position, that is, in this application, the battery unit is arranged on the bottom case through the negative tab and is electrically connected to the mounting position of the negative tab, that is, the negative tabs of each battery unit arranged on the bottom case are connected together through the mounting position on the connecting piece.

[0016] In an alternative embodiment according to the first aspect, both the positive tab and the negative tab are provided on the bottom case; the bottom case is provided with a first conductive hole, and a second conductive hole is provided at a position corresponding to the first conductive hole on the mounting position; the positive tab sequentially passes through the first conductive hole and the second conductive hole and protrudes outside the connecting piece. It should be noted that when both the positive tab and the negative tab of the battery unit are provided on the same side of the battery unit by arranging both the positive tab and the negative tab on the bottom case, at this time, the negative tab of the battery unit arranged on the bottom case is electrically connected to the connecting piece, and the positive tab of the battery unit protrudes outside the connecting piece through the first conductive hole provided on the bottom case and the second conductive hole provided on the mounting position, which is convenient for connecting the electronic device to be powered.

[0017] In an alternative embodiment according to the first aspect, the positive tab is provided on the side wall or the top case.

[0018] In an alternative embodiment according to the first aspect, the edge of the mounting position is provided with a fillet, and there is a gap between the edge of the bottom case and the fillet. It should be noted that providing a fillet at the edge of the mounting position facilitates installing the battery unit on the bottom surface of the mounting position. Setting a gap between the edge of the bottom case and the fillet can effectively prevent the edge of the bottom case from getting stuck on the side wall of the fillet, thus avoiding the situation where the bottom of the bottom case cannot be connected to the bottom surface of the mounting position.

[0019] In an alternative embodiment according to the first aspect, the gap is 0.1 mm - 0.5 mm.

[0020] The second aspect of the present invention is to provide an electronic device including the above-mentioned battery.

[0021] The battery provided by the embodiments of the present disclosure includes connection tabs and a plurality of battery cells; the connection tabs are provided with a plurality of mounting positions at intervals in a first direction and connection segments connecting adjacent mounting positions, and the battery cells are correspondingly arranged in the mounting positions; the battery cells include a housing and a battery core element accommodated in the housing; the housing of the battery cell is connected to the connection tab. In the battery provided by the present disclosure, a battery cell is arranged on each mounting position, the housing of the battery cell is connected to the connection tab, and the plurality of battery cells are connected together through the connection tab. At the same time, the entire battery assembly can be bent into a preset shape according to the specific needs of the user, so as to be easily fitted to the part to be worn, effectively meeting the needs of the user.

[0022] Since the battery and the electronic device provided by the present disclosure include the above battery, they also have the above technical effects.

Figure 2 FIG. 5 is a schematic diagram of the overall structure of the first battery provided by the embodiments of the present disclosure in the second state. Figure 3 FIG. 6 is a schematic diagram of the overall structure of the first battery provided by the embodiments of the present disclosure in the third state; please refer to Figure 1 、 Figure 2 and Figure 3 The battery provided by the embodiments of the present application includes a connecting piece 11 and a plurality of battery units 13; the connecting piece 11 is provided with a plurality of mounting positions 111 and connecting segments connecting adjacent mounting positions 111 at intervals in a first direction, and the battery units 13 are correspondingly arranged in the mounting positions 111; the battery unit 13 includes a housing and a battery cell element housed in the housing; the housing of the battery unit 13 is connected to the connecting piece 11.

[0057] The battery provided by the present disclosure includes a connecting piece 11, and the connecting piece 11 is provided with a plurality of mounting positions 111 and connecting segments connecting adjacent mounting positions 111 at intervals in a first direction. The connecting piece 11 provided by the present disclosure is the connecting piece 11, and the connecting piece 11 can be bent into the shape required by the user according to the needs of the user.

[0058] Exemplarily, the connecting piece 11 can be a conductive material, and the battery units 13 are electrically connected through the connecting piece 11. It should be noted that the specific connection method of the battery units 13 is not limited here. In other specific embodiments, the battery units 13 can be electrically connected through wires according to the needs of the user.

[0059] Exemplarily, the material of the connecting piece 11 is at least one of stainless steel, nickel-cobalt-iron alloy, manganese-nickel-copper alloy, or nickel-chromium-iron alloy. It should be noted that stainless steel, nickel-cobalt-iron alloy, manganese-nickel-copper alloy, or nickel-chromium-iron alloy are all bendable materials with good electrical conductivity. Using the above materials to make the connecting piece 11 can ensure the electrical conductivity and bending function of the connecting piece 11. It can be understood that the specific material of the connecting piece 11 is not limited here. In other specific embodiments, according to the specific needs of the user, the connecting piece 11 can also be made of other materials that can meet the electrical conductivity and bending functions.

[0060] Figure 4 The following is a schematic structural diagram of the connecting piece of the first battery provided by the embodiment of the present disclosure. Please refer to Figure 4 , exemplarily, the connecting piece 11 is provided with a plurality of bending parts 112 at intervals along the first direction, and an installation position 111 is formed between two adjacent bending parts 112. It should be noted that by arranging a plurality of bending parts 112 at intervals along the length direction of the connecting piece 11, an installation position 111 is formed between two adjacent bending parts 112. That is, in this way, the method of forming the installation position 111 is simple and easy to operate. At the same time, the bending part 112 can be used as a spacer to separate two battery units 13, and due to the structural characteristics of the bending part 112, it has a certain ductility, which helps the entire connecting piece 11 to be bent. It can be understood that the specific method of forming the installation position 111 on the connecting piece 11 is not limited here. In other specific embodiments, according to the needs of the user, other methods can also be used to form the installation position 111 on the connecting piece 11. It should also be noted that at this time, the bending part 112 is also a connecting section connecting two adjacent installation positions 111.

[0061] Exemplarily, in this embodiment, the connecting piece 11 is strip-shaped. It should be noted that setting the connecting piece 11 to be strip-shaped is convenient for forming the installation position 111 on the connecting piece 11. At the same time, setting the connecting piece 11 to be strip-shaped is convenient for bending it into a ring shape, which is convenient for wearing. Specifically, in this embodiment, the connecting piece 11 has a rectangular structure. It can be understood that the specific shape of the connecting piece 11 is not limited here. In other specific embodiments, the specific shape of the connecting piece 11 is not limited, and according to the needs of the user, the specific shape of the connecting piece 11 can be set to other strip-shaped with irregular edges.

[0062] Exemplarily, the shape of the bending part 112 can be set to be arc-shaped. It should be noted that setting the bending part 112 to be arc-shaped is convenient for the force to be relatively uniform during the bending process and has a certain resilience, so that the overall connecting piece 11 is convenient to be bent and is convenient to restore to its original shape, which is beneficial to bending into other preset shapes again.

[0063] Exemplarily, the highest point of the top end of the bending portion 112 is not higher than the top surface of the battery cell 13 disposed within the installation position 111. It should be noted that making the highest point of the top end of the bending portion 112 not higher than the top surface of the battery cell 13 disposed within the installation position 111 facilitates separating adjacent battery cells 13 to form the installation position 111, while saving the material of the connecting piece 11, thereby saving costs and reducing the overall weight of the battery assembly, which is conducive to making the product lightweight.

[0064] Exemplarily, a plurality of bending portions 112 are arranged at equal intervals. It should be noted that arranging a plurality of bending portions 112 at equal intervals facilitates making the overall structure of the connecting piece 11 compact and reasonably laid out, ensuring that the specifications of the installation positions 111 are unified, facilitating the use of unified battery cells 13, and ensuring the structural stability.

[0065] Exemplarily, the width of the bending portion 112 is from 0.5 mm to 5 mm. Exemplarily, in this embodiment, the width of the bending portion 112 is 2 mm. It should be noted that the width of the bending portion 112 is not confirmed here. In other specific embodiments, according to user requirements, the width of the bending portion 112 can be set to other appropriate values.

[0066] Exemplarily, the bottom surface of the installation position 111 can be set as a horizontal plane. It should be noted that in this embodiment, setting the bottom surface of the installation position 111 as a horizontal plane facilitates receiving the battery cell 13.

[0067] The battery provided by the present disclosure includes a battery cell 13, and the battery cell 13 includes a housing and an electric core element housed within the housing; the housing of the battery cell 13 is connected to the connecting piece 11. Exemplarily, the battery cells 13 are all connected in series or in parallel through the connecting piece 11. It should be noted that the connection method of the plurality of battery cells 13 is not limited here. In other specific embodiments, according to user requirements, the plurality of battery cells 13 can be connected in series or in parallel through the connecting piece 11, or can be set to be partially in series and partially in parallel.

[0068] Exemplarily, the housing is composed of a top case, side walls, and a mounting position 111. One end of the side walls is connected to the top case, and the other end is connected to the mounting position 111 to form a receiving cavity for accommodating the battery cell components. It should be noted that in this embodiment, the housing is composed of a top case, side walls, and a mounting position 111, that is, the mounting position 111 is used as the bottom wall of the housing, and together with the top case and side walls, it forms a receiving cavity for accommodating the battery cell components. This setting can directly utilize the material of the mounting position 111. Compared with a complete housing, when the entire housing is mounted on the mounting position 111, the setting method in this application saves more materials and reduces the overall weight of the battery. Exemplarily, in this embodiment, a plurality of through holes 115 may be provided on the connecting section of the connecting piece. It should be noted that by providing a plurality of through holes 115 on the connecting section, it is convenient to form a hollow shape, which is conducive to cooling the battery unit 13. At the same time, by providing a plurality of through holes 115 on the connecting section, the weight of the connecting piece 11 can be effectively reduced, which is convenient to realize the light weight of the whole battery, and further realizes material saving and cost reduction.

[0069] Exemplarily, the housing is composed of a top case, side walls, and a bottom case 12. One end of the side walls is connected to the top case, and the other end is connected to the bottom case 12 to form a receiving cavity for accommodating the battery cell components; the bottom case 12 is connected to the connecting piece 11. It should be noted that when the housing is directly set to include a top case, side walls, and a bottom case 12, with one end of the side walls connected to the top case and the other end connected to the bottom case 12 to form a receiving cavity for accommodating the battery cell components, it is convenient to independently mount the battery unit 13 on the mounting position 111. When one of the battery units 13 fails, it is convenient to disassemble the battery unit 13 for replacement. Compared with the above situation where the mounting position 111 is used as the bottom wall of the housing, this setting method is convenient for the replacement and maintenance of the battery unit 13. And since the overall structure of the battery unit 13 is already stably sealed, there is no need to assemble on the connecting piece 11, so the overall structure is more stable, more convenient to use, and makes the overall assembly process of the battery simpler and easier to operate, improving the assembly efficiency.
