Technical Field

[0001] This application relates to the field of fasteners, and more specifically, to a fastener, housing, battery, and device. Background Technology

[0002] With the development of communication technology, consumers have increasingly higher requirements for the reliability of mobile terminals.

[0067] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0068] With the development of communication technology, consumers have increasingly higher requirements for the reliability of mobile terminals. The batteries used in mobile devices are typically fixed to the device using bolts. However, when the device is subjected to drops or impacts, the bolts can withstand significant impact forces, causing the electrical connection between the battery and the device to loosen. After prolonged use and multiple drops or impacts, the loosening of the bolts may cause the device to fail to start.

[0069] To address at least one problem in the prior art, this patent proposes a fastener comprising a body, a connecting portion, and a force-bearing portion. Both the connecting portion and the force-bearing portion are connected to the body and are spaced apart. The connecting portion is fixedly connected to a device, and the force-bearing portion abuts against the device. When the fastener is subjected to an impact force, the impact force borne by the force-bearing portion can be dissipated through the device it abuts against. Thus, a portion of the impact force borne by the fastener is absorbed through the contact between the force-bearing portion and the device, reducing the impact force borne by the connecting portion.

[0070] It should be noted that when the connecting part is connected to the equipment but not in contact with it, i.e., the connection between the connecting part and the equipment is not secure, if the force-bearing part is sandwiched between the two surfaces of the equipment, the impact force on the fastener will be entirely borne by the force-bearing part. This ensures that the connection between the connecting part and the external equipment is unaffected by the impact force, or that the impact force is minimal. When the connecting part also abuts against the equipment, it will also bear some impact force. In this case, the impact force borne by the force-bearing part will reduce the impact force borne by the connecting part, resulting in a more reliable and less prone to loosening connection between the connecting part and the external equipment.

[0071] It should be noted that when a fastener is installed on an object and the object is fixedly connected to the equipment through the fastener, the force-bearing part is in contact with the equipment. When the equipment is subjected to vibration, impact, drop, or other operating conditions, an impact force will be generated between the object and the equipment. This impact force may cause the connection between the object and the equipment to loosen. When the force-bearing part is in contact with the equipment or sandwiched between two surfaces of the external equipment, the impact force borne by the force-bearing part can be effectively dissipated by the abutment structure, so that the connection will not loosen due to the large impact force and the fixed connection with the external equipment.

[0072] Based on this, the fastener provided in this application can reliably fix objects and external equipment using a small number of fasteners. This not only saves production costs by reducing the number of fasteners, but also simplifies the assembly process. By assembling a small number of fasteners, the fixed connection between the object and the external equipment can be highly reliable, and the fixed connection can still be maintained even in the event of multiple drops or impacts.

[0073] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0074] Please see Figure 1 , Figure 2 and Figure 3 The fastener 100 includes a body 130, a connecting part 110, and a force-bearing part 120. The connecting part 110 and the force-bearing part 120 are both fixedly connected to the body 130, and the connecting part 110 and the force-bearing part 120 are spaced apart.

[0075] It should be noted that the "interval setting" refers to the fact that the force-bearing part and the connecting part, which serve as force-bearing surfaces, are spaced apart. That is, the part of the force-bearing part that abuts against the equipment and the connecting part are spaced apart, thus ensuring that the fastener has multiple force-bearing surfaces. When the connecting part and the force-bearing part are not spaced apart, that is, when the connecting part and the force-bearing part cannot separately bear and dissipate the force, the force borne by the fastener will still be concentrated at the connecting part, causing the connecting part to bear all the impact force of the fastener.

[0076] The connecting part 110 is provided with a through hole 111 extending through the connecting part 110 along its thickness direction. The through hole 111 is suitable for inserting fasteners to fix and connect with the equipment. The connecting part 110 and the force-bearing part 120 are arranged at intervals. When the fixing part 100 is subjected to a large impact force due to external forces such as falling, the force-bearing part 120 can bear part of the impact force. Thus, the impact force borne by the fixing part 100 is shared by the force-bearing part 120, thereby reducing the impact force borne by the connecting part 110. The fixed connection between the connecting part 110 and the external equipment is more reliable and less prone to loosening.

[0077] It should be noted that the force-bearing part 120 may also be provided with through holes or other structures. That is, in some embodiments, the external appearance of the force-bearing part 120 is the same as that of the connecting part 110. During assembly, the force-bearing part 120 does not need to be fixedly connected to the device through other components. Of course, in actual manufacturing, holes are usually not drilled in the force-bearing part, as this would increase production costs and time costs. Therefore, the force-bearing part 120 of this application can not only improve the connection reliability between the fastener and the device, but also save production costs and time costs.

[0078] In some embodiments, the connection between the connecting part 110 and the device is not necessarily a fastening connection; it can also be a snap-fit ​​connection or other connection methods. For example, a snap-fit ​​part can be provided on the connecting part, and a fastening part can be provided on the device. Snapping the snap-fit ​​part into the fastening part can also achieve a fixed connection between the connecting part and the device. Alternatively, when both the connecting part and the device are made of weldable materials, such as metal, they can also be welded together. It should be noted that common connection methods in the prior art are all within the scope of protection of this application, and the connection method between the connecting part and the device is not specifically limited.

[0079] In some embodiments, multiple force-bearing parts 120 are provided, and / or multiple connecting parts 110 are provided. Providing multiple force-bearing parts 120 can distribute the impact force on the object more widely, and providing multiple connecting parts 110 can increase the reliability of the fixed connection between the object and external equipment.

[0080] It should be noted that the number of force-bearing parts 120 and the number of connecting parts 110 can be flexibly set, depending on factors such as the weight, size, production cost, and installation space of the external equipment and the object to be fixedly connected.

[0081] In some embodiments, the fastener 100 has multiple sides, and the connecting portion 110 can be respectively provided on different sides. Similarly, the force-bearing portion 120 can also be respectively provided on different sides. Due to the uncertainty of the structural form of the device it is installed on, the arrangement of the main body is also highly flexible.

[0082] refer to Figure 1 The main body 130 is a regular elongated shape. In this case, the connecting parts 110 and 120 are set on the same side. However, in some cases, the main body 130 can be in the shape of a bend, such as a U-shape, a square shape, a ring shape, an elliptical ring shape, etc. In this case, the connecting parts 110 and the force-bearing parts 120 can adjust their connection positions with the main body 130 according to the specific shape of the main body 130. No specific restrictions are made here.

[0083] For example, in some embodiments, reference is made to... Figure 3 The main body 130 is a sheet-like structure. In this case, the force-bearing part 120 and the connecting part 110 can be respectively set on two opposite sides, so that the fixed connection between the fastener 100 and the equipment can be more reliable.

[0084] It should be noted that the fastener 100 is usually a one-piece molded part, with the body 130, the connecting part 110 and the force-bearing part 120 having the same thickness. This simplifies the production cost and manufacturing process of the fastener 100 and improves its adaptability.

[0085] Of course, the thicknesses of the main body 130, the connecting part 110, and the force-bearing part 120 can also be different. The thicknesses of the three parts need to be adapted to the equipment and can be set flexibly.

[0086] It should be noted that in some cases, the body needs to be fixedly connected to the object. Therefore, the thickness of the body needs to be related to the relevant characteristics of the object to some extent. For example, if the body needs to be welded to the object, the thickness of the body needs to be appropriately thicker to ensure the success rate of the welding.

[0087] In some embodiments, the connecting portion 110 and the force-bearing portion 120 have the same thickness. The consistency of their thicknesses can improve the adaptability of the fastener 100 and at the same time facilitate production and simplify the production process.

[0088] In some embodiments, the thickness of the connecting portion 110 may be less than the thickness of the force-bearing portion 120. For example, when both the connecting portion 110 and the force-bearing portion 120 are disposed between two surfaces of the device, the thickness of the force-bearing portion 120 is greater, which ensures that the force-bearing portion 120 abuts against the two surfaces of the external device during assembly. Because the thickness of the connecting portion 110 is less than the thickness of the force-bearing portion 120, the connecting portion is not completely abutting against the two surfaces. The impact force borne by the fastener 100 will be mainly borne by the force-bearing portion 120 and dissipated through the abutting two surfaces. At this time, the fastener's fastening effect on the connecting portion 110 and the external device is not as reliable as when the connecting portion 110 is completely abutting against the two surfaces, but it can still solve the problem of loosening of the fastening connection between the connecting portion and the external device to a certain extent.

[0089] In some embodiments, the force-bearing portion 120 is provided on both sides of the connecting portion 110, so that the force-bearing portion 120 can share more of the impact force borne by the fastener 100, thereby reducing the impact force borne by the connecting portion 110 and making the fixed connection between the connecting portion 110 and the external device more stable.

[0090] Please see Figure 1 and Figure 2 The fastener 100 is provided with two force-bearing parts 120, which are alternately arranged with the connecting part 110. The two force-bearing parts 120 are respectively located on both sides of the connecting part 110, so that the impact force borne by the fastener 100 can be more evenly distributed to the force-bearing parts 120 and the connecting part 110. When the impact force borne by the fastener 100 is uneven, the impact force is prevented from being locally borne by the connecting part 110.

[0091] Furthermore, the minimum distance between the connecting part 110 and the two adjacent force-bearing parts 120 is equal, so that the impact force borne by the fastener 100 can be more evenly distributed on the two force-bearing parts 120.

[0092] It should be noted that multiple force-bearing parts can be set on only one side of the connecting part 110 to share the impact force borne by the fastener. For example, if there is one connecting part and two force-bearing parts, and the two force-bearing parts are set on the same side of the connecting part and spaced apart, the two force-bearing parts 120 can still share part of the force of the fastener, thereby improving the reliability of the connection between the fastener and the equipment.

[0093] In some embodiments, the connecting portion 110 and / or the force-bearing portion 120 extend in a direction away from the body.

[0094] The extension direction of the connecting part 110 and the force-bearing part 120 is usually determined by the structure of the equipment, because the connecting part 110 and the force-bearing part 120 need to be connected or in contact with the equipment.

[0095] Therefore, the connecting portion 110 and the force-receiving portion 120 can extend in a direction away from the body 130 or in a direction closer to the body 130. For example, if the connecting portion 110 and / or the force-receiving portion 120 are extended in a direction closer to the body, then in the thickness direction of the body 130, the orthographic projection of the connecting portion 110 and / or the force-receiving portion 120 at least partially coincides with the projection of the body 130.

[0096] Of course, the connecting part 110 and the force-bearing part 120 can extend closer to the main body and the other away from the main body. There is no specific restriction on the extension direction of the connecting part 110 and the force-bearing part 120. As long as the connecting part 110 and the force-bearing part 120 can be connected or abutted with the equipment after extension, they are all within the scope of protection of this application and no specific restriction is made here.

[0097] This application shows an embodiment in which both the connecting portion 110 and the force-bearing portion 120 extend in a direction away from the body 130.

[0098] In some embodiments, the thickness direction of the body 130 and the thickness direction of the connecting part 110 are at an angle, and / or the thickness direction of the body 130 and the thickness direction of the force-bearing part 120 are at an angle. With this setting, it is possible to adapt to the connection of various objects and various devices, making the fixed connection between objects and devices more reasonable, saving equipment space, and improving assembly efficiency.

[0099] As mentioned above, the extension direction of the connecting part 110 and the extension direction of the force-bearing part 120 do not need to be consistent. Their functions are to connect with and abut against the equipment respectively. The connecting part 110 and the force-bearing part 120 can be designed separately according to the structural characteristics of the equipment. That is, the thickness direction of the body 130 can be at an angle to the thickness direction of one of these two parts. As long as the embodiment can achieve the adaptation to the object and the adaptation to the equipment, it is within the protection scope of this application.

[0100] In some embodiments, the thickness direction of the body 130 and the included angle between the thickness directions of the two can also be the same, that is, the extension directions of the two are the same. This makes the assembly of the connecting part 110, the force-bearing part 120 and the device more convenient and optimizes the assembly process.

[0101] For example, please refer to Figure 1In the third direction Y, the thickness directions of the connecting portion 110 and the force-receiving portion 120 are the same, and the thickness direction of the body forms a 90° angle with the thickness directions of the connecting portion 110 and the force-receiving portion 120. In this case, the body 130 is suitable for connecting to the sidewall of the battery. The connecting portion and the fixing portion can be provided in the second mounting portion 2100 of the device. In some embodiments, the thickness direction of the body 130 is the same as the thickness direction of the connecting portion 110 and the force-receiving portion 120. Please refer to [reference needed]. Figure 2 and Figure 3 The fastener 100 can be located on the side of the object, or on the upper or lower surface of the object.

[0102] It should be noted that the external shape of the object is not fixed; it could be a regular square, circle, or other irregular shape. Figure 1 , Figure 2 , Figure 3 This application only shows some embodiments. Other embodiments of the fastener 100 can be designed according to the external device and the object to be fixedly connected, and no specific limitation is made here.

[0103] In some embodiments, the force-bearing part 120 and the connecting part 110 may have a height difference in their thickness direction. In this case, the force-bearing part 120 abuts between the two surfaces of the device, which can also reduce the impact force on the connecting part 110.

[0104] In some embodiments, the connecting portion 110 and the force-receiving portion 120 extend in the same direction, such as... Figure 1 and Figure 2 The connecting portion 110 and the force-bearing portion 120 protrude from the body 130 in the same direction. This allows the distance between the connecting portion 110 and the force-bearing portion 120 to be smaller, and the force-bearing portion 120 to better distribute the impact force borne by the fastener.

[0105] It should be noted that the body 130 of this application may also have a bent portion. In this case, when the force-bearing portion 120 and the connecting portion 110 are connected to the body 130, their extension directions may have an angle to meet the connection requirements of various types of objects and external devices.

[0106] In some embodiments, the thickness direction of the body 130 is the same as the thickness direction of the connecting portion 110 and / or the force-bearing portion 120, referring to... Figure 3 The main body 130 may be provided with a connecting part 110 and a force-bearing part 120 on its periphery. The main body can also be fixedly connected to an object and the object can be connected to an external device through a fastener 100. It should be noted that, in this case, the main body 100 has a large area and can be used as a surface of the object, without specific limitations.

[0107] Please see Figures 1-2In some embodiments, the fastener 100 includes two force-bearing parts 120 and a connecting part 110. The connecting part 110 is located between the two force-bearing parts 120. In this case, the force-bearing parts 120 located on both sides of the connecting part 110 can distribute the impact force borne by the connecting part 110 more evenly and efficiently.

[0108] Furthermore, the two force-bearing parts 120 adjacent to the connecting part 110 are equidistant from the connecting part 110. This improves the compatibility of the fastener 100 with external devices and also enhances the reliability of the force-bearing parts 120.

[0109] This application also provides a housing 300, which includes a housing 200 and a fastener 100 provided in this application. The fastener 100 and the housing 200 are fixedly connected. The housing 300 of this application can be fixedly connected to the device through the fastener 100.

[0110] In some embodiments, the housing 300 includes a plurality of fasteners 100, which are spaced apart, thereby enabling a fixed connection between the housing 300 and the device through the plurality of fasteners 100, thus improving the reliability of the fixed connection between the housing 300 and the device.

[0111] In some embodiments, the housing 200 includes a first wall 210 and a second wall 220 disposed opposite to each other, and at least two fasteners 100 are respectively connected to the first wall 210 and the second wall 220. The two fasteners 100 are respectively connected to the first wall 210 and the second wall 220, and the connecting portion 110 is fixedly connected to different parts of the external device, thereby improving the connection reliability between the housing 300 and the external device.

[0112] In some embodiments, please refer to Figure 4 The housing 300 includes four fasteners 100. Two fasteners 100 are spaced apart on the first wall surface 210, and two fasteners 100 are spaced apart on the second wall surface 220. When the housing 200 is long, that is, when the first wall surface 210 and the second wall surface 220 extend in a long direction, two fasteners 100 are spaced apart on the first wall surface 210 and the second wall surface 220, respectively, which can improve the reliability of the fixed connection between the housing and the equipment.

[0113] Further reference Figure 4 The fasteners 100 are symmetrically arranged along the central axis of the housing 200. The central axis of the housing 200 can be the central axis extending in its length direction or the central axis in its width direction.

[0114] It should be noted that the reference Figure 4When the housing 200 has a first wall 210 and a second wall 220, the thickness direction of the body 130 can be the same as the thickness direction of the first wall 210 and / or the second wall 220, so that the body 130 and the first wall 210 and / or the second wall 220 are in surface contact, increasing the area of ​​the fixed connection. At this time, the thickness direction of the body 130 is at an angle to the thickness direction of the connecting part 110 and the force-bearing part 120.

[0115] In some embodiments, the thickness direction of the body 130 may not be the same as the thickness direction of the first wall surface 210 and / or the second wall surface 220, as shown in the reference. Figure 6 The main body 130 is fixedly connected to a side wall away from the connecting part 110 and the first wall surface 210 and / or the second wall surface 220. The connection area between the main body 130 and the first wall surface 210 and / or the second wall surface 220 is reduced, but the production cost of the fastener 100 is reduced, which can enhance the market competitiveness of the fastener 100.

[0116] In some embodiments, the housing 200 has an opening, and the body 130 is adapted to be fixedly connected to the housing 200. Furthermore, this fixed connection can close the opening. See also... Figure 3 and Figure 5 The outer shell 300 can be assembled by welding the main body 130 and the shell 200, which simplifies the assembly process of the outer shell 300.

[0117] It should be noted that 200 can be the middle frame. In this case, the housing 200 has two openings that are arranged opposite each other. The fastener 100 and the housing 200 are fixedly connected to close one of the openings. At this time, the outer shell 300 has one opening. After the battery cell is installed into the outer shell 300, the opening of the outer shell 300 is closed with a cover plate, and a usable battery can be produced.

[0118] In some embodiments, the fixing member 100 may also be a structural member with a receiving cavity and an opening. In this case, the housing 200 may be a cover plate. The housing 200, which serves as the cover plate, and the fixing member 100 with a receiving cavity and an opening are fixedly connected. Furthermore, the housing 200, which serves as the cover plate, can close the opening of the fixing member 100 with a receiving cavity, thus forming a battery with a closed receiving cavity.

[0119] This application also provides a battery 1000, which includes a casing 300 and a battery cell provided in this application. The casing 300 has a receiving cavity, and the battery cell is disposed in the receiving cavity. The battery 1000 of this application can be fixedly connected to the device 2000 through the connecting part 110, and the force-bearing part 120 bears part of the impact force of the fixing member 100, so that the fixed connection between the connecting part 110 and the device 2000 is more reliable and less prone to loosening.

[0120] In some embodiments, the battery 1000 further includes a protection board assembly 400. The battery has a polarity element, and the protection board assembly 400 is electrically connected to the polarity element. The protection board assembly 400 enables the electrical connection between the battery 1000 and the device.

[0121] Furthermore, the battery is provided with polarity components including a positive electrode and a negative electrode, which can be at least one of a tab, a post, and a housing. After the battery cell is housed in the receiving cavity of the housing 300, the polarity components are usually electrically connected to the battery cell, and pass through the housing 200 and extend to the outside of the housing to facilitate the assembly of the electrical connection.

[0122] Furthermore, the protection board assembly 400 will be equipped with relevant components for realizing information control, acquisition and monitoring of the battery, as well as connectors, which are used to connect with the device 2000 to realize the electrical connection between the protection board assembly 400 and the device 2000.

[0123] It should be noted that, in some embodiments, the protection board assembly 400 includes a connector and a protection board. One end of the connector is connected to the polarity component, and the other end of the connector is connected to the protection board. The connector can not only realize the electrical connection between the polarity component and the protection board, but also improve the setting flexibility of the protection board when the connector is a flexible component. At the same time, it can improve the layout flexibility of the device 2000. The connector can make the protection board placed in the layout space of the device 2000, thereby improving the energy density of the battery.

[0124] This application also provides a device 3000, which includes a device 2000 and a mounting portion 2100. The device 3000 also includes at least one of the fastener 100, housing 300, and battery 1000 provided in this application, and is disposed in the mounting portion 2100. The connecting portion 110 is connected to the mounting portion 2100.

[0125] In some embodiments, the fastener 100 is not only a connecting tool, but the body 130 of the fastener 100 is itself a functional component, that is, the body 130 itself is an object that needs to be connected to the device. In this case, the fastener 100 and the device 2000 are fixedly connected, and the device protected by this application can be produced.

[0126] It should be noted that device 2000 is a terminal that can realize its related functions, and housing 300 is a shell with a receiving cavity. The difference between device 2000 and housing 300 is already shown from their name definitions.

[0127] In some embodiments, a housing 300 needs to be mounted on the device 2000 to form a device with its functions. For example, a housing 300 with a connection portion 110 and a force-bearing portion 120 and having a cavity is provided on the device 2000, so that the device has the function of accommodating objects. Such a device is also within the protection scope of this application. In this case, the housing 300 is provided on the mounting portion 2100.

[0128] In some embodiments, the device 2000 is an electrical device, and the device 2000 is provided with a mounting portion 2100 to accommodate the battery 1000. The device 2000 and the battery 1000 are electrically connected so that the battery 1000 supplies power to the device 2000.

[0129] In some embodiments, the mounting portion 2100 is provided with a first mounting hole 2121, the battery 1000 is disposed in the mounting portion 2100, and the fastener 500 passes through the through hole 111 and is fastened to the first mounting hole 2121. The fastener 500 achieves a fixed connection between the battery 1000 and the device 2000.

[0130] The battery 1000 used in the device 3000 of this application is provided with a force-bearing part 120. The force-bearing part 120 shares the impact force of the fixing part 100. When the device 3000 is subjected to impact force due to conditions such as falling, especially when subjected to a large impact force, the force-bearing part 120 bears the impact force, thereby reducing the impact force of the connecting part 110 and making the fastening connection between the fastener 500 and the device 2000 more reliable.

[0131] In some embodiments, reference Figure 8 The mounting section 2100 includes a first mounting section 2110, a second mounting section 2120 and a third mounting section 2130.

[0132] The housing 200 is disposed in the first mounting part 2110, the connecting part 110 and the force-bearing part 120 are disposed in the second mounting part 2120, and the second mounting part 2120 is provided with a first mounting hole 2121; the protective plate assembly 400 is at least partially disposed in the third mounting part 2130.

[0133] In some embodiments, the second mounting portion 2120 is provided with a plurality of first grooves 2123, the connecting portion 110 and the force-bearing portion 120 are provided in the first grooves 2123, at least a portion of the first grooves 2123 are provided with first mounting holes 2121, and at least a portion of the first mounting holes 2121 and through holes 111 are correspondingly provided. By setting the connecting portion 110 in the first grooves 2123, and the fastener 500 passing through the through holes 111 and being fastened to the first mounting holes 2121, a fixed connection between the battery 1000 and the device 2000 is achieved.

[0134] In the thickness direction of the device 2000, the orthographic projections of the connecting part 110 and the force-receiving part 120 are both within the orthographic projection of the first groove 2123.

[0135] Furthermore, the first groove 2123 is provided with a shape corresponding to the connecting part 110 and the force-receiving part 120, so that the first groove 2123 can also limit the connecting part 110 and the force-receiving part 120 in the direction perpendicular to its thickness, thereby further improving the connection reliability and stability of the battery 1000 and the device 2000.

[0136] In some embodiments, in the first direction Y, the depth H3 of the first groove 2123, the connecting portion 110 having a first maximum thickness H1, and the force-bearing portion 120 having a second maximum thickness H2; H3≤H1 and / or H3≤H2. It should be noted that the connecting portion 110 and the force-bearing portion 120, after being disposed in the first groove 2123, need to protrude from the second mounting portion 2120, or the connecting portion 110 and the force-bearing portion 120, after being disposed in the first groove 2123, need to remain flush with the second mounting portion 2120 in the first direction. When the first shell portion is disposed on the device 2000, the first shell portion covers the mounting portion 2100, and at least a portion of the surface of the first shell portion facing the mounting portion 2100 can abut against the connecting portion 110 and / or the force-bearing portion 120. Of course, the first groove 2123 has a recessed bottom, and the side of the connecting portion 110 and / or the force-bearing portion 120 away from the first shell portion abuts against the recessed bottom.

[0137] The first direction Y is the thickness direction of device 2000.

[0138] It should be noted that if at least a portion of the surface of the first shell facing the mounting portion 2100 only abuts against the force-bearing portion 120, when the fastener 100 is to be dislodged from the device in the direction of the opening of the mounting portion, the force-bearing portion 120 will bear the impact force of the fastener 100, making it difficult for the fastener to separate from the device, and also improving the reliability of the connecting portion 110 and the device 2000.

[0139] In some embodiments, the connector of the protection plate assembly 400 may be located in the third mounting portion 2130, and the protection plate of the protection plate assembly 400 may be located in other layout spaces of the device 2000. This allows the third mounting portion 2130 to occupy less space in the mounting portion 2100, thereby increasing the space of the first mounting portion 2110 and thus increasing the energy density of the battery.

[0140] Of course, if the fastener 100 or the housing 300 provided in the mounting section 2100 does not include the protective plate assembly, then there is no need to provide a third mounting section.

[0141] In some embodiments, the device 3000 further includes a pressure plate 600, which is disposed on the mounting portion 2100 and on the side of the force-bearing portion 120 away from the device 2000, so that the force-bearing portion 120 is disposed between the mounting portion 2100 and the pressure plate 600; the force-bearing portion 120 and the pressure plate 600 abut against each other, and / or the force-bearing portion 120 and the mounting portion 2100 abut against each other.

[0142] In some embodiments, the pressure plate 600 is provided with a through hole 601, and the through hole 601 and the through hole 111 are correspondingly provided. The fastener 500 passes through the through hole 601 and the through hole 111 in sequence and is fastened to the first mounting hole 2121. The connecting part 110 abuts between the mounting part 2100 and the pressure plate 600, or the connecting part 110 is provided between the mounting part 2100 and the pressure plate 600.

[0143] In some embodiments, when the connecting part 110 does not simultaneously abut against the pressure plate 600 and the mounting part 2100, but the force-bearing part 120 simultaneously abuts against the pressure plate 600 and the mounting part 2100, the impact force borne by the fastener 100 will be borne by the force-bearing part 120 and resolved through this abutment relationship.

[0144] In some embodiments, when the connecting part 110 simultaneously abuts against the pressure plate 600 and the mounting part 2100, and the force-bearing part 120 also simultaneously abuts against the pressure plate 600 and the mounting part 2100, the impact force borne by the fastener 100 will be jointly borne by the force-bearing part 120 and the connecting part 110 and resolved through this abutting relationship.

[0145] In some embodiments, reference Figure 8 The second mounting part 2120 also includes a second groove, and the pressure plate 600 is disposed in the second groove. The pressure plate can be limited in the direction perpendicular to the thickness of the device 2000 through the second groove.

[0146] In some embodiments, reference Figure 8 In the first direction Y, the orthographic projection of the pressure plate 600 and the orthographic projection of the housing 200 are completely misaligned to avoid the pressure plate 600 squeezing the battery 1000, thereby affecting the stability of the battery.

[0147] Of course, in the first direction Y, the orthographic projection of the pressure plate 600 is within the orthographic projection of the mounting part 2100, which also ensures that the pressure plate 600 does not affect the assembly of the device 2000 and improves the adaptability of the device.

[0148] In some embodiments, reference Figure 8The second mounting part 2120 is also provided with a second mounting hole 2122. The second mounting hole 2122 and the first groove 2123 are spaced apart. At least part of the through hole 601 and the second mounting hole 2122 are provided correspondingly. The fastener 500 passes through the through hole 601 and is fastened to the second mounting hole 2122, thereby realizing the fixed connection between the pressure plate 600 and the second mounting part 2120. The fixed connection between the pressure plate 600 and the device 2000 is more reliable, further improving the reliability of the fixed connection between the battery 1000 and the device 2000.

[0149] It should be noted that the pressure plate 600 can be a pressure strip, or a back plate or back shell for a sealing device. Any structural component that can provide a surface energy for the force-bearing part 120 to be used with the device 2000 can be used as the pressure plate 600 of this application. This application does not have specific restrictions on the shape and structure of the pressure plate.

[0150] The device 3000 in this application is not limited to mobile phones, vehicles, or laptops. Any device that can achieve a fixed connection and improve the reliability of the connection through the fasteners in this application is within the scope of protection of this application, and no specific limitations are made here.
