[0017] In an optional embodiment according to the second aspect, the connecting section is a bent section, and the protrusion of the bent section is oriented in the direction of the groove depth of the receiving groove. It should be noted that the connecting section is a bent section, and the connecting section is located between two adjacent receiving grooves, that is, a bent section is provided between two adjacent receiving grooves, and the protrusion of the bent section is oriented in the direction of the groove depth of the receiving groove. The bent section can serve as a spacer to separate the two receiving grooves, and due to the structural characteristics of the bent portion, it has a certain degree of ductility, which can facilitate bending of the entire shell.

[0018] In an optional embodiment according to the second aspect, the highest point of the top of the bent section is no higher than the outer bottom surface of the receiving groove. It should be noted that this facilitates reducing the overall thickness of the housing, saving housing material, saving costs, and reducing the overall weight of the housing, thereby achieving a lightweight product.

[0019] In an optional embodiment according to the second aspect, a sealing cover for sealing the receiving groove is provided at the opening of the receiving groove. It should be noted that the provision of the sealing cover can form the receiving groove into a sealed space. In this case, the battery cell unit is accommodated in the receiving groove and the sealing cover is welded. The receiving groove and the sealing cover together form the outer shell of the battery cell component, thereby ensuring the structural stability of the battery cell component.

[0020] In an optional embodiment according to the second aspect, the battery cell components are all electrically connected in series or in parallel via the shell substrate.

The negative tab of the battery cell body and the adapter can be welded or snap-fitted. Welding ensures the stability of the connection between the battery cell body and the adapter; snap-fitting the negative tab of the battery cell body to the adapter facilitates removal of the battery cell body from the adapter. The adapter and the bottom of the accommodating groove can also be welded or clamped. When the adapter is welded to the bottom of the accommodating groove, the stability of the connection between the adapter and the accommodating groove can be ensured; when the adapter is clamped to the bottom of the sinking groove, the adapter and the battery cell body can be easily removed from the bottom of the sinking groove.

[0057] Currently, most portable electronic devices are worn on the user's body, for example, some are worn on the wrist. Existing wrist-worn portable electronic devices often use wristbands, with the battery installed within the main body. Such electronic devices require the battery to be curved to conform to their shape. However, these portable electronic devices are generally large, causing significant discomfort to the user, thus reducing the user experience.

[0058] In view of this, the shell provided in the embodiment of the present application is unable to be bent according to the needs of the user according to the portable electronic devices in the prior art. A shell base is provided, and a plurality of receiving grooves for installing energy storage components are arranged at intervals on the shell base, which facilitates the dispersed arrangement of the energy storage components. The entire shell base can be bent into a preset shape according to the specific needs of the user, and then it is convenient to match the part to be worn, which can effectively meet the needs of the user.

[0059] Specifically, the shell provided by the embodiment of the present disclosure includes a shell base material; the shell base material includes at least two receiving grooves spaced apart along a first direction and a connecting section connecting adjacent receiving grooves; the receiving grooves include skirt portions symmetrically arranged along a second direction; the length of the connecting section is greater than the width of the skirt portion. The shell provided by the present disclosure includes a shell base material, and at least two receiving grooves are spaced apart on the shell base material. During use, the energy storage component can be installed in the receiving groove, which satisfies the need to install multiple energy storage components together. At the same time, the entire shell base material can be bent into a preset shape according to the specific needs of the user, thereby facilitating the fit of the shell base material to the part to be worn, effectively meeting the needs of the user.

[0060] Figure 1 This is a schematic diagram of the structure of the first housing provided by the embodiment of the present disclosure. Figure 1 The shell provided in the embodiment of the present application includes a shell substrate 11; the shell substrate 11 includes at least two accommodating grooves 113 spaced apart along a first direction and a connecting section 117 connecting adjacent accommodating grooves 113; the accommodating grooves 113 include skirt portions 118 symmetrically arranged along a second direction; the length of the connecting section 117 is greater than the width of the skirt portion 118.

[0061] It should be noted that in this embodiment, the first direction and the second direction are perpendicular to each other. It is understandable that the specific positional relationship between the first direction and the second direction is not limited here. In other specific embodiments, the first direction and the second direction can be set to different directions according to user needs, that is, set at an angle.

[0062] The shell provided by the present disclosure includes a shell substrate 11, and the shell substrate 11 includes at least two accommodating grooves 113 spaced apart along a first direction and a connecting section 117 connecting adjacent accommodating grooves 113. Exemplarily, the material of the shell substrate 11 can be a flexible material, which is convenient for the user to bend it into a preset shape according to needs during use. Furthermore, the shell substrate 11 can be set to a conductive material for electrically connecting multiple energy storage components through the shell substrate 11. Exemplarily, the shell substrate 11 can be at least one of stainless steel, nickel-cobalt-iron alloy, manganese-nickel-copper alloy or nickel-chromium-iron alloy. It can be understood that the conductivity of the shell substrate 11 is not limited here. In other specific embodiments, the shell substrate 11 can also be made of non-conductive material according to user needs. In this case, multiple battery cell bodies can be connected by wires.

[0063] For example, the thickness of the housing substrate 11 can be set to be less than 200 microns. It is understood that in other specific embodiments, the thickness of the housing substrate 11 can be set to other sizes according to user needs, for example, equal to or greater than 200 microns.

[0064] Figure 3 This is a schematic diagram of the structure of the first type of battery cell element provided by the embodiment of the present disclosure at a first viewing angle. Figure 3 For example, the receiving groove 113 can be a rectangular groove, and the battery cell element 13 can be a rectangular body that matches the shape of the rectangular groove. It is understood that the specific shapes of the receiving groove 113 and the battery cell element 13 are not limited here. In other specific embodiments, the receiving groove 113 can also be configured as other shapes, such as a circular groove or an elliptical groove, according to user needs, and the battery cell element 13 can be adaptively configured as a cylindrical or elliptical cylinder, etc.

[0065] For example, multiple receiving slots 113 are arranged at equal intervals. It should be noted that arranging multiple receiving slots 113 at equal intervals facilitates the overall structure of the housing to be compact and rationally arranged, and ensures the uniformity of the specifications of the installation positions, facilitates the uniformity of the battery cell components 13, and ensures the stability of the structure.

[0066] Exemplarily, the bottom of the receiving groove 113 is set as a horizontal surface. It should be noted that the bottom of the receiving groove 113 is set as a horizontal surface to facilitate the stable reception of the battery cell element 13.

[0067] The housing's receiving groove 113 includes skirt portions 118 symmetrically arranged along the second direction. The length of the connecting section 117 is greater than the width of the skirt portion 118. It should be noted that the provision of the skirt portion 118 ensures the structural strength of the receiving groove 113, preventing deformation of the housing substrate 11 constituting the receiving groove 113 and squeezing of the energy storage component within the receiving groove 113. Furthermore, it provides sufficient welding area for the subsequent welding of the sealing cover 114. By setting the length of the connecting section 117 to be greater than the width of the skirt portion 118, the connection strength of each receiving groove 113 can be enhanced while reducing the overall volume of the housing.

[0068] Exemplarily, the connecting section 117 connects the skirt portions 118 of adjacent receiving grooves 113. It should be noted that the connecting section 117 connects the skirt portions 118 of adjacent receiving grooves 113 to better play a supporting and holding role.

[0069] For example, the connecting section 117 is provided with a plurality of through holes. It should be noted that providing a plurality of through holes on the connecting section 117 can facilitate forming a hollow shape, thereby facilitating cooling of the battery element or telecommunications device installed in the receiving groove 113. At the same time, providing a plurality of through holes can effectively reduce the weight of the housing, facilitate achieving a lightweight housing as a whole, and further achieve material conservation and cost reduction.

[0070] Exemplarily, the plurality of through holes provided on the connecting section 117 are distributed in a rectangular array. Exemplarily, the cross-sectional shape of the through holes can be set to a circular or polygonal shape. It is understood that the specific cross-sectional shape of the through holes is not limited here. In other specific embodiments, the cross-sectional shape of the through holes can be set to an elliptical or other irregular shape according to user needs.

[0071] For example, the connecting section 117 is a bent section 112, and the protrusion of the bent section 112 is oriented toward the depth direction of the receiving groove 113. It should be noted that the connecting section 117 is a bent section 112, and the connecting section 117 is located between two adjacent receiving grooves 113, that is, the bent section 112 is provided between the two adjacent receiving grooves 113, and the protrusion of the bent section 112 is oriented toward the depth direction of the receiving groove 113. The bent section 112 can serve as a spacer to separate the two receiving grooves 113, and due to the structural characteristics of the bent portion, it has a certain degree of ductility, which can help the entire shell to bend.

[0072] For example, the highest point of the top of the bent section 112 is not higher than the outer bottom surface of the receiving groove 113. It should be noted that this is convenient for reducing the overall thickness of the housing, saving housing materials, saving costs, and reducing the overall weight of the housing, thereby making the product lightweight.

[0073] For example, the shape of the bending section 112 can be an arc. It should be noted that setting the shape of the bending section 112 to an arc facilitates relatively uniform force during the bending process and has a certain degree of resilience, making it easy for the entire shell to bend and restore its original shape, which is conducive to bending again into other preset shapes.

[0074] For example, the housing substrate 11 is in the shape of an elongated strip, and the receiving groove 113 is a groove punched out along the length of the elongated strip. It should be noted that the elongated shape of the housing substrate 11 facilitates bending into a ring shape for easier wearing. It is understood that the specific shape of the housing substrate 11 is not limited here. In other specific embodiments, the housing substrate 11 can also be configured in other shapes according to user needs.

[0075] The present disclosure also provides a battery, including a shell and a battery cell element 13, the shell including a shell substrate 11; the shell substrate 11 includes at least two receiving grooves 113 spaced apart along a first direction and a connecting section 117 connecting adjacent receiving grooves 113; the battery cell element 13 is accommodated in the receiving grooves 113; the battery cell elements 13 in adjacent receiving grooves 113 are connected through the shell substrate 11. The battery provided by the present disclosure includes a battery cell unit, which is installed in the receiving groove 113. During use, the battery cell unit can be installed in the receiving groove 113, which satisfies the need to install multiple energy storage components together. At the same time, the entire shell substrate 11 can be bent into a preset shape according to the specific needs of the user, so as to facilitate the fit with the part to be worn, which can effectively meet the needs of the user.

[0076] Exemplarily, the receiving slots 113 include skirt portions 118 symmetrically arranged along the second direction; the length of the connecting section 117 is greater than the width of the skirt portion 118. It should be noted that setting the length of the connecting section 117 greater than the width of the skirt portion 118 can enhance the connection strength of each receiving slot 113 while reducing the overall volume of the housing.

[0077] Exemplarily, the connecting section 117 connects the skirt portions 118 of adjacent receiving grooves 113. It should be noted that the connecting section 117 connects the skirt portions 118 of adjacent receiving grooves 113 to better play a supporting and holding role.

[0078] Exemplarily, the material of the shell substrate 11 can be a flexible material, which is convenient for the user to bend it into a preset shape according to needs during use. Furthermore, the shell substrate 11 can be set to a conductive material for electrically connecting multiple energy storage components through the shell substrate 11. Exemplarily, the shell substrate 11 can be at least one of stainless steel, nickel-cobalt-iron alloy, manganese-nickel-copper alloy or nickel-chromium-iron alloy. The thickness of the shell substrate 11 can be set to less than 200 microns. It can be understood that in other specific embodiments, the thickness of the shell substrate 11 can be set to other sizes according to user needs, for example, equal to or greater than 200 microns.

[0079] For example, the connecting section 117 is provided with a plurality of through holes. It should be noted that providing a plurality of through holes on the connecting section 117 can facilitate forming a hollow shape, thereby facilitating cooling of the battery element or telecommunications device installed in the receiving groove 113. At the same time, providing a plurality of through holes can effectively reduce the weight of the housing, facilitate achieving a lightweight housing as a whole, and further achieve material conservation and cost reduction.

[0080] For example, the connecting section 117 is a bent section 112, and the protrusion of the bent section 112 is oriented toward the depth direction of the receiving groove 113. It should be noted that the connecting section 117 is a bent section 112, and the connecting section 117 is located between two adjacent receiving grooves 113, that is, the bent section 112 is provided between the two adjacent receiving grooves 113, and the protrusion of the bent section 112 is oriented toward the depth direction of the receiving groove 113. The bent section 112 can serve as a spacer to separate the two receiving grooves 113, and due to the structural characteristics of the bent portion, it has a certain degree of ductility, which can help the entire shell to bend.

[0081] For example, the highest point of the top of the bent section 112 is not higher than the outer bottom surface of the receiving groove 113. It should be noted that this is convenient for reducing the overall thickness of the housing, saving housing materials, saving costs, and reducing the overall weight of the housing, thereby making the product lightweight.

[0082] Exemplarily, a sealing cover 114 for sealing the accommodating groove 113 is provided at the opening of the accommodating groove 113. It should be noted that the sealing cover 114 is provided to form a sealed space in the accommodating groove 113. In this case, the battery cell unit is accommodated in the accommodating groove 113, and the sealing cover 114 is welded. The accommodating groove 113 and the sealing cover 114 together constitute the outer shell of the battery cell element 13, thereby ensuring the structural stability of the battery cell element 13. It can be understood that the energy storage component accommodated in the accommodating groove 113 is not limited here. In other specific embodiments, the battery cell can be adaptively installed in the accommodating groove 113 according to the needs of the user. The battery cell element 13 here is a bare battery cell, that is, a bare battery cell composed of a positive electrode, a negative electrode and a diaphragm. The bare battery cell is formed into a battery cell after liquid injection and packaging. In other words, the battery cell element 13 can be placed in the accommodating groove 113 disclosed in the present application to form a battery cell, or a battery cell can be placed directly. For example, when a battery cell is installed in the receiving groove 113 , the sealing cover 114 is not required. The battery cell is installed in the receiving groove 113 , and the depth of the receiving groove 113 is greater than or equal to the thickness of the battery cell.

[0083] Exemplarily, the battery cell components 13 are all electrically connected in series or in parallel through the shell substrate 11. It should be noted that the battery cell components 13 are all electrically connected in series or in parallel through the shell substrate 11. Here, the shell substrate 11 acts as a wire for series or parallel connection, eliminating the need for a dedicated wire, making the overall structure simpler. It should also be noted that the connection method of the multiple battery cell components 13 is not limited here. In other specific embodiments, the multiple battery cell components 13 can be connected in series or in parallel through the shell substrate 11 according to user needs, and can also be set to be partially connected in series and partially connected in parallel.

[0084] Figure 2This is a schematic diagram of the structure of the second housing provided in the embodiment of the present disclosure. Figure 2 , exemplarily, the battery further includes an adapter 12; the battery cell element 13 includes a battery cell body and a positive electrode ear 131 and a negative electrode ear provided on the battery cell body; the two sides of the adapter 12 are electrically connected to the negative electrode ear of the battery cell element 13 and the receiving groove 113 respectively. It should be noted that the negative electrode ear of the battery cell element 13 is connected to the shell substrate 11 through the adapter 12, and the positive electrode ear 131 of the battery cell element 13 is used to connect to the electronic device to facilitate power supply. The provision of the adapter 12 facilitates the connection between the battery cell element 13 and the receiving groove 113 through the adapter 12. When one of the battery cell elements 13 has a problem, it can be removed from the receiving groove 113 together with the adapter 12 for replacement. Exemplarily, when the battery element is set as a rectangular body structure, the adapter 12 can be adaptively set as a rectangular disc structure.

[0085] Figure 4 This is a schematic diagram of the structure of the first type of battery cell element provided by the embodiment of the present disclosure at a second viewing angle. Figure 4 For example, the positive electrode tab 131 and the negative electrode tab are both arranged on the bottom surface of the battery cell body; a first conductive hole 121 is provided at the bottom of the adapter 12, and a second conductive hole 1111 is provided at the position of the accommodating groove 113 corresponding to the first conductive hole 121; the positive electrode tab 131 passes through the first conductive hole 121 and the second conductive hole 1111 in sequence, and protrudes out of the shell substrate 11.

[0086] It should be noted that both the positive tab 131 and the negative tab are disposed on the bottom surface of the cell body; that is, when the positive tab 131 of the cell body and the negative tab of the cell body are disposed on the same side of the cell body, the negative tab of the cell body is electrically connected to the shell substrate 11 via the adapter 12. The positive tab 131 of the cell body protrudes outside the shell substrate 11 through the first conductive hole 121 provided at the bottom of the adapter 12 and the second conductive hole 1111 provided on the receiving groove 113, making it easy to connect to the electronic device to be powered. The negative tab of the cell body and the adapter 12 can be welded or clamped. When welding is used, the stability of the connection between the cell body and the adapter 12 can be ensured; when the negative tab of the cell body and the adapter 12 are clamped, the cell body can be easily removed from the adapter 12. The adapter 12 and the bottom of the accommodating groove 113 can also be welded or clamped. When the adapter 12 is welded to the bottom of the accommodating groove 113, the stability of the connection between the adapter 12 and the accommodating groove 113 can be ensured; when the adapter 12 is clamped to the bottom of the sinking groove, the adapter 12 together with the battery cell body can be easily removed from the bottom of the sinking groove.

[0087] Figure 5 This is a schematic diagram of the structure of the second type of battery cell element provided by the embodiment of the present disclosure. Figure 5 In other specific embodiments, to accommodate the structural requirements of electronic devices, the positive tab 131 can be positioned on the side or top surface of the cell body, while the negative tab can be positioned on the bottom surface of the cell body. When the positive tab 131 is positioned on the side of the cell body, a conductive hole for the positive tab 131 to pass through can be adaptively provided on the sidewall of the receiving groove 113 at a location corresponding to the positive tab 131.

[0088] Figure 6 This is a schematic structural diagram of the third housing provided by the embodiment of the present disclosure at a first viewing angle. Figure 7 This is a schematic diagram of the structure of the third housing provided by the embodiment of the present disclosure at a second viewing angle. Figure 6 and Figure 7 , exemplarily, the edge of the receiving groove 113 is provided with a rounded corner 116, and there is a gap between the edge of the adapter 12 and the rounded corner 116. It should be noted that the edge of the receiving groove 113 is provided with a rounded corner 116, which facilitates the installation of the battery cell body on the bottom surface of the receiving groove 113. Providing a gap between the edge of the adapter 12 and the rounded corner 116 can effectively prevent the edge of the adapter 12 from being stuck on the side wall of the receiving groove 113, thereby preventing the bottom of the adapter 12 from being unable to connect with the bottom surface of the receiving groove 113. Exemplarily, the gap is 0.1mm-0.5mm.
