Abstract
Description
Technical Field
[0001] This application relates to the field of equipment assembly technology, and in particular to an electronic device. Background Technology
[0002] With the continuous development of electronic technology, more and more electronic devices are becoming miniaturized, which means that the space left for components in electronic devices is getting smaller and smaller. This has also led some electronic devices to adopt more flexible assembly methods. Snap-fit structures are a common choice for many products. Snap-fit structures are also a widely used connection method, and a relatively economical, effective, simple, and convenient connection method.
[0003] A well-designed snap-fit structure allows for rapid assembly and disassembly of components, sometimes without the need for tools. However, there is a risk that the snaps may spring open when the product is dropped or subjected to external impact, leading to connection failure and rendering the product inoperable. Therefore, preventing the snap-fit structure from opening to improve the reliability of electronic devices is an important issue. Utility Model Content
[0004] The purpose of this application is to provide an electronic device that can help avoid the pop-out phenomenon of the snap-fit structure, thereby improving the reliability of the electronic device.
[0005] To address the aforementioned technical problems, embodiments of this application provide an electronic device. The electronic device includes a housing, a bracket, and a circuit board. The housing has a receiving cavity and multiple limiting portions located within the receiving cavity. The bracket is disposed within the receiving cavity and has a mounting surface and multiple latches. Each latch includes a main body protruding from the surface of the bracket and an engaging portion protruding from one side of the main body, the engaging portion being spaced apart from the mounting surface. The circuit board abuts against the mounting surface and has multiple cutout areas corresponding one-to-one with the multiple latches. The engaging portion of each latch passes through the corresponding cutout area and abuts against the side of the circuit board away from the mounting surface. The multiple limiting portions correspond one-to-one with the multiple latches, each limiting portion being located on the side of the corresponding latch's main body away from the engaging portion and positioned along the latch's spring-opening path.
[0006] The electronic device provided in this application has a limiting part provided within the receiving cavity of the housing. The circuit board is mounted on a bracket via a snap-fit structure and is fixed in place by the snap-fit structure. The engaging part of the snap-fit abuts against one side of the circuit board, while the limiting part is located on the side of the main body of the snap-fit away from the engaging part. Furthermore, the limiting part is located on the snap-fit's spring-opening path, thus restricting the snap-fit's spring-opening. This creates a barrier near the snap-fit, preventing deformation and avoiding spring-opening of the snap-fit structure, thereby improving the reliability of the electronic device.
[0007] In some embodiments, the circuit board includes a first edge and a second edge disposed opposite to each other, with a portion of a plurality of cutout areas disposed adjacent to the first edge and another portion of the plurality of cutout areas disposed adjacent to the second edge. This disperses the plurality of cutout areas, ensuring the stability of the circuit board when mounted on a support.
[0008] In some embodiments, at least some of the multiple latches are arranged opposite each other, with the engaging portions of the oppositely arranged latches located on sides close to each other. This allows the circuit board to be positioned relative to each other from opposite directions, thus providing a limiting effect.
[0009] In some implementations, portions of the multiple snap-fits are located on the same straight line, and the engaging portions of the snap-fits on the same straight line are located on the same side of the line. This simplifies the circuit board assembly process by arranging some snap-fits along a straight line.
[0010] In some implementations, the bracket is provided with guide posts, and the circuit board is provided with through holes corresponding to the guide posts, through which the guide posts pass. In this way, the guide posts can guide the assembly of the circuit board and achieve a positioning effect.
[0011] In some embodiments, the housing includes a first part and a second part connected together. The first part has a receiving cavity and an opening communicating with the receiving cavity, and the second part covers the opening. In this way, the housing can be formed by using an outer shell and a cover, which simplifies the assembly structure of the housing.
[0012] In some embodiments, both the first and second parts are provided with limiting portions. This allows the limiting portions to be distributed across different parts of the housing to accommodate the engagement direction of the latches on the bracket.
[0013] In some embodiments, the limiting portion is a rib provided in the first part and / or the second part. In this way, by providing ribs to form a limiting portion, the shell structure is strengthened while the buckle is limited.
[0014] In some implementations, the first part and the second part are detachably connected. This detachable connection reduces the difficulty of assembling the housing and facilitates disassembly.
[0015] In some implementations, the cutout area is a notch or through-hole provided on the edge of the circuit board. This allows for the creation of cutout areas at different locations by providing notches or through-holes on the circuit board to cooperate with clips. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.
[0028] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," and "joining" 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0029] As electronic devices continue to become smaller and lighter, simpler and more convenient snap-fit structures are being used to connect the various components. For example, in portable storage devices such as USB flash drives and external hard drives, or in small positioning devices, snap-fit mechanisms are used on plastic parts to secure circuit boards. This snap-fit connection effectively secures the components in their positions and simplifies assembly, allowing for disassembly and assembly without the need for tools.
[0030] However, because the movement of the snap-fit structure is not completely restricted, it is prone to popping open due to external influences. This can cause the secured components to detach, rendering the product malfunctioning and affecting its reliability.
[0031] To avoid affecting product reliability due to instability in the snap-fit structure, some embodiments of this application provide an electronic device. The component assembly structure in the electronic device is optimized, forming a restraining structure after component assembly. This restraining structure is located on the path of the snap-fit's release. This makes the product's reliability more stable. Even if the product is dropped or subjected to external impact, the snap-fit will not deform and release due to the structural restraint, providing a stable fixing effect on the component.
[0032] The following is combined with Figures 1 to 9 This application describes the structure of an electronic device provided in some embodiments.
[0033] like Figures 1 to 9As shown, some embodiments of this application provide an electronic device including a housing 11, a bracket 12, and a circuit board 13. The housing 11 has a receiving cavity 101 and a plurality of limiting portions 102 located within the receiving cavity 101. The bracket 12 is disposed within the receiving cavity 101, and has a mounting surface 121 and a plurality of latches 122. Each latch 122 includes a main body portion 1221 protruding from the surface of the bracket 12, and an engaging portion 1222 protruding from one side of the main body portion 1221. The engaging portion 1222 is spaced apart from the mounting surface 121. The circuit board 13 abuts against the mounting surface 121. The circuit board 13 has a plurality of hollow areas 131 corresponding one-to-one with the plurality of latches 122. The engaging portion 1222 of each latch 122 passes through the corresponding hollow area 131 and abuts against the side of the circuit board 13 away from the mounting surface 121. Multiple limiting parts 102 correspond one-to-one with multiple latches 122. Each limiting part 102 is located on the side of the main body 1221 of the corresponding latch 122 away from the engaging part 1222, and is located on the spring-opening path of the latch 122.
[0034] The housing 11 is the encapsulation part of the electronic device, forming the mounting base for other components. Simultaneously, the housing 11 protects other components, preventing them from being easily affected by external factors. The receiving cavity 101 is the mounting space formed inside the housing 11, capable of accommodating other components. The overall outer contour of the housing 11 can be set into a regular cuboid shape, prism shape, or cylinder shape, or it can be set into an irregular irregular shape. A limiting part 102 is provided within the receiving cavity 101 of the housing 11, forming a limiting structure that can be used to limit the latches 122 on other components.
[0035] The bracket 12 is a component in the electronic device used to mount the circuit board 13. The bracket 12 facilitates the assembly of the circuit board 13. After the circuit board 13 mates with the bracket 12 to form a single unit, the bracket 12 can then be inserted into the receiving cavity 101 of the housing 11. The bracket 12 is provided with mounting surfaces 121, which can be continuous or distributed, meaning the circuit board 13 can mate with the same area on the bracket 12 or with different areas. Threaded holes can be provided at the mounting surfaces 121 for fastener assembly, achieving a fixed connection between the circuit board 13 and the bracket 12. A receiving space can be formed in the middle portion of the bracket 12 to avoid obstructing components on the circuit board 13. Simultaneously, the bracket 12 can have notches to avoid obstructing connectors on the circuit board 13. A latch 122 is provided on the bracket 12, including a main body 1221 protruding from the surface of the bracket 12 and an engaging portion 1222 protruding from one side of the main body 1221. The buckle 122 has elastic deformation characteristics, which can deform when subjected to external pressure and return to its original shape after the external force is removed.
[0036] Circuit board 13 is an important part of the electronic device. Circuit board 13 can be used to arrange circuits to achieve specific functions. One side surface of circuit board 13 abuts against the mounting surface 121 of bracket 12. Circuit board 13 has a cutout area 131 for a portion of the latch 122 to pass through. After circuit board 13 is installed in place, the engaging portion 1222 of latch 122 abuts against the opposite side surface of circuit board 13 to fix circuit board 13. At the same time, after bracket 12 is installed into housing 11, limiting portion 102 inside housing 11 is located adjacent to latch 122 and on the spring-opening path of latch 122, restricting the spring-opening of latch 122. This prevents latch 122 from malfunctioning.
[0037] The electronic device provided in some embodiments of this application has a limiting part 102 provided in the receiving cavity 101 of the housing 11. The circuit board 13 is mounted on the bracket 12 by a snap-fit structure and is fixed by the snap-fit structure. The snap-fit part 1222 of the latch 122 abuts against one side of the circuit board 13, while the limiting part 102 is located on the side of the main body 1221 of the latch 122 away from the snap-fit part 1222. Furthermore, the limiting part 102 is located on the spring-opening path of the latch 122 and can limit the spring-opening of the latch 122. Thus, a barrier is formed near the latch 122, preventing the latch 122 from deforming and avoiding the latch 122 from springing open, thereby improving the reliability of the electronic device.
[0038] In some embodiments, such as Figure 4 and Figure 5 As shown, the circuit board 13 may include a first edge 132 and a second edge 133 disposed opposite to each other, a portion of a plurality of cutout areas 131 disposed adjacent to the first edge 132, and another portion of the plurality of cutout areas 131 disposed adjacent to the second edge 133.
[0039] The first edge 132 and the second edge 133 are partial edges of the circuit board 13, and the cutout areas 131 are distributed at different edges of the circuit board 13. By distributing the cutout areas 131, the stability of the circuit board 13 when mounted on the bracket 12 can be ensured. The circuit board 13 can engage with the clips 122 on the bracket 12 at different positions. The circuit board 13 can be set in a regular shape such as rectangular, square, or circular, or it can be set in an irregular shape. Multiple cutout areas 131 can be distributed at the corners of the circuit board 13, thereby forming a locking structure in the direction surrounding the center of the circuit board 13, providing an effective and stable fixing effect for the assembly of the circuit board 13. Figure 4 and Figure 5As shown, the number of cutout areas 131 and latches 122 is set to four. The four cutout areas 131 are distributed on both sides of the circuit board 13, and the two cutout areas 131 on the same edge are set far apart from each other. Thus, without affecting the components on the circuit board 13, the cooperation between the cutout areas 131 and the latches 122 forms an effective and stable limiting effect on the circuit board 13.
[0040] In addition, such as Figures 3 to 5 As shown, at least some of the multiple latches 122 can be arranged opposite each other, and the engaging portions 1222 of the oppositely arranged latches 122 are located on the side that are close to each other.
[0041] In other words, multiple latches 122 can be grouped into pairs, with the two latches 122 in the same group maintaining a relative position. This causes the engaging portions 1222 of the two opposing latches 122 to face each other, thus limiting the movement of the circuit board 13 from opposite directions. This prevents the circuit board 13 from easily moving relative to the bracket 12 after it engages with it. The number of opposing latches 122 can be two, four, or six. In practice, the engaging portions 1222 of the latches 122 can also face different directions, effectively limiting the assembly position of the circuit board 13.
[0042] In some embodiments, portions of the plurality of latches 122 may be located on the same straight line, and the engaging portions 1222 of the latches 122 located on the same straight line are located on the same side of the straight line.
[0043] like Figure 4 and Figure 5 As shown, some of the latches 122 are arranged along a straight line, and the engaging portions 1222 of the latches 122 located on the same straight line face the same direction. In this way, the cooperation between the individual latches 122 restricts the movement of the circuit board 13 toward the side of the main body 1221 of the latch 122 away from the engaging portion 1222, preventing the latches 122 from disengaging. Figure 4 and Figure 5 In the illustrated configuration, multiple latches 122 are positioned along the corners of the circuit board 13. The engaging portions 1222 of two latches 122 located near the first edge 132 of the circuit board 13 face opposite directions, as do the engaging portions 1222 of two latches 122 located near the second edge 133 of the circuit board 13. Simultaneously, two latches 122 are aligned on the same straight line, with their engaging portions 1222 facing the same side. The other two latches 122 are positioned opposite each other. This interlocking of the multiple latches 122 reduces the assembly difficulty of the circuit board 13 while ensuring a secure hold after assembly.
[0044] In some embodiments, the mounting surface 121 of the bracket 12 may be provided with a guide post 123, and the circuit board 13 is provided with a through hole 134 corresponding to the guide post 123, through which the guide post 123 passes.
[0045] The guide post 123 serves a guiding function during the assembly of the circuit board 13. The number of guide posts 123 can be one or more, and they provide positioning during the assembly of the circuit board 13. The circuit board 13 can be installed by aligning the through holes 134 on the circuit board 13 with the positions of the guide posts 123 on the bracket 12, allowing the guide posts 123 to pass through the through holes 134 on the circuit board 13. This completes the engagement between the clip 122 and the circuit board 13.
[0046] like Figures 6 to 8 As shown, the housing 11 may include a first part 111 and a second part 112 connected together. The first part 111 is provided with a receiving cavity 101 and an opening 103 communicating with the receiving cavity 101. The second part 112 covers the opening 103.
[0047] In other words, the housing 11 adopts a front shell plus a rear cover form. The first part 111 of the housing 11 has an inner cavity and a snap fastener 122, and the second part 112 of the housing 11 is used to close the opening 103, thereby forming the encapsulation shell of the electronic device. Figure 9 As shown, after the bracket 12 is assembled with the circuit board 13, it can be inserted into the first part 111 of the housing 11. The first part 111 of the housing 11 can be provided with a guide structure within the receiving cavity 101 to guide the bracket 12 and restrict its installation position within the receiving cavity 101. Then, through the cooperation between the second part 112 and the first part 111, the bracket 12 is fixed within the receiving cavity 101. In practice, the housing 11 may also include two parts with internal cavities, which, after being connected, together form the receiving cavity 101. The housing 11 may also be in the form of a bottom shell plus a top cover, with the receiving cavity 101 formed on the bottom shell. Furthermore, when the circuit board 13 is provided with a connector, a protrusion 113 with an outlet can be provided in the first part 111 of the housing 11 to accommodate the connector's interface portion and protect it.
[0048] In some embodiments, both the first portion 111 and the second portion 112 of the housing 11 may be provided with a limiting portion 102.
[0049] In other words, when the engaging portion 1222 of the latch 122 faces different directions, in order to facilitate the limiting effect on the main body 1221 of the latch 122, the limiting portions 102 can be distributed at appropriate positions in the first part 111 and the second part 112. For example, when there are four latches 122 and four hollow areas 131, two of the limiting portions 102 can be placed in the first part 111 and the other two in the second part 112. This facilitates the movement of each limiting portion 102 into the corresponding latch 122 after the final assembly of the electronic device, thus limiting the movement of the main body 1221 of the corresponding latch 122 away from the engaging portion 1222 and preventing the latch 122 from popping open.
[0050] In addition, the limiting part 102 may be a rib provided in the first part 111 and / or the second part 112.
[0051] Ribs can be provided on the inner wall surfaces of the first portion 111 and / or the second portion 112 of the housing 11 to improve structural strength. Some of these ribs are positioned corresponding to the buckle 122 to form a limiting part 102, which can provide a blocking effect on the opposite side of the buckle 122. Figure 7 As shown, the first part 111 of the housing 11 can be provided with higher ribs to form a limiting part 102, which has a blocking effect on the snap-on opening of the buckle 122. Figure 8 As shown, the second part 112 of the housing 11 can be provided with ribs to prevent the buckle 122 from popping open.
[0052] In practice, the first part 111 and the second part 112 can be detachably connected.
[0053] In other words, a snap-fit structure can also be used to connect and fix the first part 111 and the second part 112 of the housing 11. This simplifies the cost of the electronic device and the assembly process of the housing 11. At the same time, it facilitates the disassembly of the housing 11 for inspection and maintenance of the internal parts of the electronic device.
[0054] In some embodiments, the cutout area 131 can be a notch or through hole provided on the edge of the circuit board 13.
[0055] Specifically, a cutout area 131 for the engagement of the latch 122 can be provided by creating through holes in the empty areas of the circuit board 13 or by creating notches at the edges of the circuit board 13. Through holes can help limit the latch 122, while notches can help the latch 122 disengage, allowing the circuit board 12 to be disassembled. By setting different types of engagement structures at different locations on the circuit board 12, the assembly effect of the circuit board 12 can be ensured while reducing the assembly difficulty of the circuit board 12.
[0056] Those skilled in the art will understand that the above embodiments are specific implementations of this application, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this application.
