[0034] The embodiments of this application are described in detail below. Examples of these 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 intended to explain this application, and should not be construed as limiting this application.

[0035] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0038] Electronic devices can refer to device structures that internally house multiple electronic components; for example, the electronic components inside an electronic device include, but are not limited to, batteries, circuit boards, buzzers, and sensors. Electronic devices have a wide range of applications, and depending on the different electrical components they contain, they can be used as alarm devices, detection devices, identification devices, and many other purposes. In related technologies, electronic devices are typically used by hand or mounted on the side or top wall of a supporting structure; therefore, electronic devices are subject to the risk of being dropped. When an electronic device is dropped, its internal electronic components are easily damaged under impact, leading to malfunction. Therefore, improving the internal stability of electronic devices to reduce the probability of damage from drops is an urgent problem to be solved.

[0039] Based on the above considerations, in order to solve the problem of electronic devices being easily damaged when dropped in related technologies, an electronic device is designed. By limiting and accommodating a large circuit board within a limiting and accommodating groove, the stability of the circuit board is improved. At the same time, an elastic abutment part is provided on the cover of the protective cover, which abuts against the battery to improve the stability of the battery connection to the circuit board. In this way, by improving the assembly stability of the large circuit board and simultaneously improving the connection stability of the heavy battery, the internal impact resistance of the electronic device is effectively improved when dropped, thereby effectively reducing the probability of damage to the electronic device when dropped.

[0040] The electronic device provided in this application will now be described in detail with reference to specific embodiments.

[0041] Please refer to Figures 1 to 7 This application provides an electronic device 1000, including a housing 100, a circuit board 200, and a power module 300; the housing 100 includes a first housing 110 and a second housing 120, which are connected and overlap each other; a limiting component 400 is provided on the side of the first housing 110 facing the second housing 120, and the limiting component 400 and the first housing 110 enclose a limiting receiving groove 111; the circuit board 200 is limited and accommodated within the limiting receiving groove 111; the power module 300... Module 300 includes a battery 310 and a protective cover 320. The battery 310 is disposed on the circuit board 200 and electrically connected to the circuit board 200. The protective cover 320 includes a covering portion 321 and two connecting portions 322 disposed on opposite sides of the covering portion 321. The covering portion 321 is disposed on the other side of the battery 310 opposite to the circuit board 200, and the connecting portions 322 are connected to the circuit board 200. The covering portion 321 is also provided with an elastic abutting portion 321a, which abuts against the battery 310.

[0042] Here, the housing 100 refers to the encapsulation structure of the entire electronic device 1000 used to house electronic components.

[0043] The housing 100 includes a first housing 110 and a second housing 120; the first housing 110 and the second housing 120 can be fastened together to protect the internal electronic components. Optionally, the first housing 110 and the second housing 120 can be two independent parts, and the first housing 110 and the second housing 120 can be formed into one piece by closing; or, the first housing 110 and the second housing 120 can be hinged to form one piece.

[0044] The limiting component 400 is used to enclose and form a limiting receiving groove 111 with the first housing 110; the limiting component 400 includes, but is not limited to, a limiting block, a limiting plate, a limiting protrusion, a limiting buckle, and other structures. The circuit board 200 is limited and received within the limiting receiving groove 111, and the limiting component 400 can perform a locking and limiting function on the circuit board 200, so that the circuit board 200 is fixedly assembled between the first housing 110 and the limiting component 400.

[0045] The limiting component 400 is disposed on the side of the first housing 110 facing the second housing 120. Optionally, the limiting component 400 can be connected to the first housing 110 by means of fastener fixation, heat fusion fixation, integral molding, etc. In this way, when the first housing 110 and the second housing 120 are closed and connected, the limiting component 400 and the circuit board 200 housed in the limiting receiving groove 111 can be located inside the first housing 110 and the second housing 120.

[0046] The power module 300 includes a battery 310 and a protective cover 320; it should be understood that the battery 310 in this embodiment may refer to a button cell battery, which is electrically connected to the circuit board 200 to provide power.

[0047] The protective cover 320 is used to cover and protect the battery 310. The protective cover 320 includes a covering part 321 and a connecting part 322; wherein, the covering part 321 is disposed on the other side of the battery 310 opposite to the circuit board 200, so that the covering part 321 can cover the battery 310 and provide protection for the battery 310; that is, a battery compartment for accommodating the battery 310 can be formed between the covering part 321 and the circuit board 200.

[0048] Optionally, the cover 321 can be made of stainless steel; stainless steel has superior structural strength, and the stainless steel cover 321 has a lower probability of breaking in the event of a drop.

[0049] One end of the connecting part 322 is connected to the covering part 321, and the other end of the connecting part 322 is connected to the circuit board 200; thus, the covering part 321 is fixedly mounted on the circuit board 200 through the connecting part 322.

[0050] Optionally, the connecting part 322 can be connected to the circuit board 200 by means of fastener connection, bonding, welding, etc. The connecting part 322 and the cover part 321 can be integrally formed, so that the overall structural strength of the protective cover 320 is better.

[0051] The cover portion 321 is also provided with an elastic abutment portion 321a; optionally, the elastic abutment portion 321a may be, but is not limited to, an elastic abutment sheet, a spring, or other elastic structures. The number of elastic abutment portions 321a may be one, two, or more. The cover portion 321 is fixedly mounted relative to the circuit board 200, and at the same time, the elastic abutment portion 321a can abut against the battery 310; thus, the battery 310 can be relatively fixed to the circuit board 200 under the action of the elastic abutment portion 321a; and in the event of a collision or impact, the elastic abutment portion 321a can form a certain buffering effect according to its own elasticity, thereby reducing the probability of a rigid collision between the heavy battery 310 and the circuit board 200 and the cover portion 321.

[0052] The electronic device 1000 provided in this application improves the stability of the circuit board 200 by limiting and accommodating the larger circuit board 200 within the limiting and accommodating groove 111. At the same time, an elastic abutment portion 321a is provided on the cover portion 321 of the protective cover 320, and the elastic abutment portion 321a abuts against the battery 310 to improve the stability of the battery 310 connected to the circuit board 200. In this way, by improving the assembly stability of the larger circuit board 200 and simultaneously improving the connection stability of the heavier battery 310, the internal impact resistance of the electronic device 1000 is effectively improved when it is dropped, thereby effectively reducing the probability of damage to the electronic device 1000 when it is dropped.

[0053] Please refer to Figures 1 to 7 In some embodiments, the covering portion 321 has a weight-reducing hole 321b, and the end of the elastic abutting portion 321a used for abutting is directly opposite the weight-reducing hole 321b.

[0054] Optionally, one or more weight-reducing holes 321b may be formed on the covering portion 321; the weight-reducing holes 321b may be, but are not limited to, round holes, rectangular holes, strip holes, etc. The weight-reducing holes 321b may be formed at any location on the covering portion 321, for example, they may be formed at the center of the covering portion 321, or they may be formed off-center from the center of the covering portion 321.

[0055] For example, in some embodiments, only one weight-reducing hole 321b may be formed on the covering part 321, and the weight-reducing hole 321b is located at the center of the covering part 321; the cross-sectional area of ​​the weight-reducing hole 321b is greater than 0.1 and less than or equal to 0.5 of the total surface area of ​​the covering part 321, so that the weight-reducing effect of the weight-reducing hole 321b can be achieved, while also reducing the impact on the strength of the covering part 321.

[0056] In this embodiment, the elastic contact portion 321a can be formed at any location of the covering portion 321, for example, it can be formed on the surface of the covering portion 321 or on the inner wall surface of the weight reduction hole 321b.

[0057] The end portion of the elastic abutment portion 321a used for abutment is directly opposite the weight reduction hole 321b, that is, in the axial direction of the weight reduction hole 321b, the projection of the end portion of the elastic abutment portion 321a is within the range of the weight reduction hole 321b. In this way, the end portion of the elastic abutment portion 321a used for abutment can be exposed through the weight reduction hole 321b to facilitate observation of the elastic abutment portion 321a abutting against the battery 310.

[0058] With this configuration, the overall weight of the cover 321 is reduced by opening the weight-reducing hole 321b, so that the cover 321 is lighter in the event of a drop, and the probability of the cover 321 being damaged during a drop is also lower.

[0059] Please refer to Figures 1 to 7 In some embodiments, the thickness of the covering portion 321 is h, where 0.25mm ≤ h ≤ 0.3mm.

[0060] In this embodiment, the thickness h of the covering portion 321 is set to be greater than or equal to 0.25 mm and less than or equal to 0.3 mm; thus, the covering portion 321 has sufficient thickness to cover and protect the battery 310, and at the same time, it can effectively reduce the risk of excessive weight and cost impact caused by the covering portion 321 being too thick.

[0061] Please refer to Figures 1 to 7 In some embodiments, the connecting portion 322 includes a first pin portion 322a and a connected second pin portion 322b. The first pin portion 322a is connected to the connecting portion 322. A positioning hole 201 is provided on the circuit board 200. The width of the first pin portion 322a is d, the width of the second pin portion 322b is f, and the width of the positioning hole 201 is g, wherein d > g > f. The second pin portion 322b is inserted into the positioning hole 201, and the first pin portion 322a abuts against and is connected to the circuit board 200.

[0062] It should be understood that the first pin portion 322a and the second pin portion 322b refer to two parts of the connecting portion 322, that is, the first pin portion 322a is the part of the connecting portion 322 that is close to the cover portion 321, and the second pin portion 322b is the other part of the connecting portion 322 that is away from the cover portion 321.

[0063] For example, in some embodiments, the connecting portion 322 may be in the form of a sheet structure, the first pin portion 322a and the second pin portion 322b are respectively in the form of rectangular sheet structures, and the rectangular area of ​​the first pin portion 322a is larger and the rectangular area of ​​the second pin portion 322b is smaller.

[0064] The circuit board 200 has a positioning hole 201 for positioning and inserting the second pin portion 322b. Thus, when the first pin portion 322a is fixedly connected to the circuit board 200, the second pin portion 322b is positioned and inserted into the positioning hole 201, effectively improving the stability of the entire connection portion 322. Exemplarily, in some embodiments, when the second pin portion 322b is a rectangular sheet structure, the positioning hole 201 can be a strip-shaped hole to facilitate the insertion of the second pin portion 322b.

[0065] It should be understood that by setting the size relationship between the width d of the first pin portion 322a, the width f of the second pin portion 322b, and the width g of the positioning hole 201 as: d > g > f; during the assembly process, the second pin portion 322b can be positioned and inserted into the positioning hole 201, and the first pin portion 322a moves into the positioning hole 201 along with the second pin portion 322b until the second pin portion 322b abuts against the end of the circuit board 200 at the opening of the positioning hole 201, and then the second pin portion 322b is fixedly connected to the circuit board 200.

[0066] Optionally, the second pin portion 322b and the circuit board 200 can be connected by means of bonding, soldering, or other methods. In this embodiment, soldering can be used for connection and fixation to improve the connection stability between the second pin portion 322b and the circuit board 200.

[0067] Please refer to Figures 1 to 7 In some embodiments, a chamfer 322c is formed at the connection between the first pin portion 322a and the second pin portion 322b, and the radius of the chamfer 322c is r, 0.5mm≤r≤1mm.

[0068] The connection point between the first pin portion 322a and the second pin portion 322b refers to the connection point formed between the surface of the first pin portion 322a that is away from the cover portion 321 and the surface of the second pin portion 322b that intersects with it.

[0069] Chamfer 322c refers to the bevel cutting process performed at the connection between the first pin portion 322a and the second pin portion 322b, which is used to remove the sharp or right angle edge formed at the connection between the first pin portion 322a and the second pin portion 322b to form a curved surface.

[0070] It should be understood that, since the first pin portion 322a and the second pin portion 322b are sheet structures, both the first pin portion 322a and the second pin portion 322b have a certain degree of elasticity; under impact or shock conditions, the first pin portion 322a and the second pin portion 322b will collide or rub against the circuit board 200. Therefore, by forming a chamfer 322c at the connection point of the first pin portion 322a and the second pin portion 322b, the gap between the connection point of the first pin portion 322a and the second pin portion 322b and the circuit board 200 is reduced, thereby reducing the probability of the first pin portion 322a and the second pin portion 322b wobbling relative to the circuit board 200. Thus, the probability of friction or collision between the first pin portion 322a and the second pin portion 322b and the circuit board 200 can be effectively reduced.

[0071] In this embodiment, the radius at the chamfer 322c is limited to greater than or equal to 0.5 mm and less than or equal to 1 mm; thus, the fit between the first pin portion 322a and the second pin and the circuit board 200 is better.

[0072] Please refer to Figures 1 to 7 In some embodiments, the length of the second pin portion 322b is k, where 3mm ≤ k ≤ 4mm.

[0073] Understandably, the length k of the second pin portion 322b refers to the distance from one end of the second pin portion 322b that connects to the first pin portion 322a to the opposite end of the second pin portion 322b that is away from the first pin portion 322a.

[0074] In this embodiment, the length k of the second pin portion 322b is limited to greater than or equal to 3mm and less than or equal to 4mm. This ensures the depth of the second pin portion 322b inserted into the positioning hole 201, and also reduces the probability of the second pin portion 322b being too long and therefore prone to shaking.

[0075] Please refer to Figures 1 to 7 In some embodiments, the limiting component 400 includes a first limiting portion 410 and a second limiting portion 420. At least two first limiting portions 410 are spaced apart in the first direction X, and at least two second limiting portions 420 are spaced apart in the second direction Y. The at least two first limiting portions 410, the at least two second limiting portions 420 and the first housing 110 together enclose and form a limiting receiving groove 111. The first direction X intersects with the second direction Y.

[0076] The first limiting part 410 may be, but is not limited to, a limiting plate, a limiting block, a limiting protrusion, a limiting rib, or other structures. The number of the first limiting parts 410 may be any number of two, three, or more.

[0077] For example, in some embodiments, there are two first limiting portions 410, and the two first limiting portions 410 are spaced apart in the first direction X; in this way, the circuit board 200 can be locked between the two first limiting portions 410.

[0078] The second limiting part 420 may be, but is not limited to, a limiting plate, a limiting block, a limiting protrusion, a limiting rib, or other structures. The number of the second limiting parts 420 may be any number of two, three, or more.

[0079] For example, in some embodiments, there are two second limiting portions 420, and the two second limiting portions 420 are spaced apart in the second direction Y; in this way, the circuit board 200 can be locked between the two second limiting portions 420.

[0080] The first direction X intersects with the second direction Y; optionally, the first direction X and the second direction Y can be any two intersecting directions. For example, the first direction X and the second direction Y can be the length direction and the width direction of the first housing 110, respectively, and the first direction X and the second direction Y can be perpendicular to each other.

[0081] With this configuration, the circuit board 200 can be engaged in the intersecting first direction X and second direction Y, thus improving the assembly stability of the circuit board 200.

[0082] Please refer to Figures 1 to 7 In some embodiments, the limiting component 400 further includes a third limiting part 430 and a fourth limiting part 440; the third limiting part 430 is provided with a first latching part 431 protruding toward the limiting receiving groove 111, and at least two third limiting parts 430 are spaced apart in the first direction X, the circuit board 200 is located between the spaced at least two third limiting parts 430, and the first latching part 431 abuts against the side surface of the circuit board 200 facing away from the first housing 110.

[0083] And / or, the fourth limiting part 440 is provided with a second latching part (not shown in the figure) protruding toward the limiting receiving groove 111. In the second direction Y, at least two fourth limiting parts 440 are spaced apart. The circuit board 200 is located between the spaced-apart at least two fourth limiting parts 440, and the second latching part abuts against the side surface of the circuit board 200 facing away from the first housing 110.

[0084] The third limiting part 430 may be, but is not limited to, a limiting plate, a limiting block, a limiting protrusion, a limiting rib, or other structures. The number of the third limiting parts 430 may be any number of two, three, or more.

[0085] The third limiting part 430 is also provided with a first locking part 431 facing the limiting receiving groove 111; the first locking part 431 may be, but is not limited to, a block structure, a rod structure, a protrusion structure, etc., provided on the third limiting part 430. It should be understood that when the circuit board 200 is limited and engaged between the spaced third limiting parts 430, the first locking part 431 can abut against the side surface of the circuit board 200 facing away from the first housing 110, so as to achieve a locking effect on the circuit board 200 in the direction perpendicular to the first direction X and the second direction Y.

[0086] For example, in some embodiments, there are two third limiting portions 430, and the two third limiting portions 430 are spaced apart in the first direction X; the third limiting portions 430 protrude toward the limiting receiving groove 111 and form a first locking portion 431, wherein the first locking portion 431 may be in the form of a triangular block structure; in this way, the circuit board 200 can be inserted into the limiting receiving groove 111 along the inclined surface of the triangular block structure, and is locked onto the circuit board 200 along the bottom surface of the triangular block structure.

[0087] The fourth limiting part 440 may be, but is not limited to, a limiting plate, a limiting block, a limiting protrusion, a limiting rib, or other structures. The number of the fourth limiting parts 440 may be any number of two, three, or more.

[0088] And / or, the fourth limiting portion 440 is provided with a second locking portion facing the limiting receiving groove 111; the second locking portion may be, but is not limited to, a block structure, a rod structure, a protrusion structure, etc., provided on the fourth limiting portion 440. It should be understood that when the circuit board 200 is locked between the spaced fourth limiting portions 440, the second locking portion can abut against the side surface of the circuit board 200 facing away from the first housing 110, so as to achieve a locking effect on the circuit board 200 in the direction perpendicular to the first direction X and the second direction Y.

[0089] For example, in some embodiments, there are two fourth limiting portions 440, and the two fourth limiting portions 440 are spaced apart in the second direction Y; the fourth limiting portions 440 protrude toward the limiting receiving groove 111 and form a second locking portion, wherein the second locking portion may be in the form of a triangular block structure; in this way, the circuit board 200 can be inserted into the limiting receiving groove 111 along the inclined surface of the triangular block structure, and is locked onto the circuit board 200 along the bottom surface of the triangular block structure.

[0090] Please refer to Figures 1 to 7In some embodiments, at least two third limiting portions 430 are staggered in the first direction X; and / or, at least two fourth limiting portions 440 are staggered in the second direction Y.

[0091] In the first direction X, at least two third limiting portions 430 are spaced apart and staggered; that is, the projections of the spaced third limiting portions 430 are separated in the first direction X. Exemplarily, in some embodiments, when there are two third limiting portions 430, the projections of the two third limiting portions 430 along the first direction X are separated, that is, one of the two third limiting portions 430 is located on one side of the first direction X and offset towards one side of the second direction Y, and the other of the two third limiting portions 430 is located on the opposite side of the first direction X and offset towards the opposite side of the second direction Y.

[0092] And / or, in the second direction Y, at least two fourth limiting portions 440 are spaced apart and staggered; that is, in the second direction Y, the projections of the spaced fourth limiting portions 440 are separated. Exemplarily, in some embodiments, when there are two fourth limiting portions 440, the projections of the two fourth limiting portions 440 in the second direction Y are separated, that is, one of the two fourth limiting portions 440 is located on one side in the second direction Y and offset towards one side in the first direction X, and the other of the two fourth limiting portions 440 is located on the opposite side in the second direction Y and offset towards the opposite side in the first direction X.

[0093] With this configuration, the first latch 431 on the third limiting part 430 and the second latch on the fourth limiting part 440 can limit and lock the circuit board 200. The misalignment of the first latch 431 and the second latch can effectively reduce the assembly difficulty of the circuit board 200.

[0094] Please refer to Figures 1 to 7 In some embodiments, one end of the first housing 110 is hinged to one end of the second housing 120. The first housing 110 is provided with a first latching part 112 at the hinged end, and the second housing 120 is provided with a second latching part 121 at the hinged end. The first latching part 112 and the second latching part 121 are engaged in a latching relationship. The second housing 120 is also provided with an abutting rib 122, which is configured to abut against the circuit board 200 when the first latching part 112 and the second latching part 121 form a latching connection.

[0095] In this embodiment, one end of the first housing 110 is hinged to one end of the second housing 120; thus, the first housing 110 and the second housing 120 can rotate around the hinge to realize the opening and closing operation between the first housing 110 and the second housing 120.

[0096] Meanwhile, the first housing 110 is provided with a first latching part 112 at the other end of the hinge, and the second housing 120 is provided with a second latching part 121 at the other end of the hinge; thus, when the first housing 110 and the second housing 120 rotate around the hinge and close together, the first latching part 112 and the second latching part 121 can form a latching connection, thereby realizing the closing connection operation of the first housing 110 and the second housing 120.

[0097] The first latching part 112 and the second latching part 121 engage with each other; that is, the first latching part 112 and the second latching part 121 can be interlocked to form a connection. Optionally, the first latching part 112 and the second latching part 121 can be a latching structure and a slot structure, respectively; for example, the first latching part 112 is a latching structure and the second latching part 121 is a slot structure; in this way, when the first housing 110 and the second housing 120 rotate around the hinge and close, the latching structure can be inserted into the slot structure and achieve a latching connection.

[0098] The second housing 120 is also provided with abutment ribs 122; optionally, the abutment ribs 122 may be, but are not limited to, columnar structures, plate-like structures, protrusion structures, etc.; the number of abutment ribs 122 may be one, two, or more than two. The abutment ribs 122 may be provided at any location on the side of the second housing 120 facing the first housing 110, as long as the abutment ribs 122 can abut against the circuit board 200 when the second housing 120 and the first housing 110 are closed.

[0099] With this configuration, when the first housing 110 and the second housing 120 are fitted together, the first latching part 112 and the second latching part 121 form a latching connection. At this time, the abutment rib 122 abuts against the circuit board 200 to further improve the installation stability of the circuit board 200. In the event of a collision or impact, the probability of the circuit board 200 shaking is lower.

[0100] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
