Technical Field
[0001] This utility model relates to the field of electronic equipment technology, and in particular to an electronic equipment motherboard and electronic equipment. Background Technology
[0002] Electronic devices refer to devices or apparatuses that use electronic technology to achieve specific functions. Their core characteristic is that they process and manipulate electrical signals through electronic circuits (such as integrated circuits, semiconductor components, etc.). Common electronic devices include chargers, smartphones, televisions, stereos, headphones, etc.
[0003] Currently, some existing electronic devices are quite large, take up a lot of space, and are not easy to store. Therefore, how to reduce the size of electronic devices is one of the topics that the industry needs to study. Utility Model Content
[0004] This invention provides an electronic device motherboard and an electronic device, which solves the technical problem of how to reduce the size of electronic devices.
[0005] The first aspect of this application provides an electronic device motherboard, comprising: a main substrate; electronic components disposed on one side of the main substrate; and a contact spring terminal or a conductive annular groove disposed on the other side of the main substrate, wherein the contact spring terminal or the conductive annular groove is used for sliding electrical connection with a telescopic wire module.
[0006] In some embodiments, the thickness of the main substrate is in the range of 0.6 mm to 0.8 mm.
[0007] In some embodiments, the main substrate is provided with a plurality of contact spring terminals on the side away from the electronic components, the first end of each contact spring terminal is electrically connected to the main substrate, and the second end of each contact spring terminal has a gap with the main substrate.
[0008] In some embodiments, each of the contact spring terminals includes an electrical contact point for electrical connection with the telescopic wire module, and the distance between the electrical contact point and the main substrate is in the range of 2mm to 3mm.
[0009] In some embodiments, the plurality of contact spring terminals include a first power terminal, a second power terminal, a first data terminal, a second data terminal, and a third data terminal; the first data terminal, the second data terminal, and the third data terminal are located between the first power terminal and the second power terminal, and the width of the first power terminal and the second power terminal is greater than the width of the first data terminal, the second data terminal, and the third data terminal.
[0010] In some embodiments, the widths of the first power terminal and the second power terminal are in the range of 0.48 mm to 0.65 mm.
[0011] In some embodiments, the widths of the first data terminal, the second data terminal, and the third data terminal are in the range of 0.28 mm to 0.45 mm.
[0012] In some embodiments, a terminal mounting portion is further included. The terminal mounting portion is connected to the side of the main substrate facing away from the electronic components. The terminal mounting portion is equipped with a contact spring terminal. The terminal mounting portion has a flat plate structure, and its thickness direction is consistent with the thickness direction of the main substrate.
[0013] In some embodiments, the thickness of the terminal mounting portion is in the range of 0.4 mm to 0.6 mm.
[0014] A second aspect of this application provides an electronic device, comprising: the aforementioned electronic device motherboard; and a retractable cable module capable of extending or retracting a data cable, wherein the contact spring terminal or the conductive annular groove of the electronic device motherboard is slidably electrically connected to the retractable cable module.
[0015] This invention provides an electronic device motherboard with contact spring terminals or conductive annular grooves as electrical connection structures. This allows the electronic device motherboard to be directly and slidably electrically connected to a retractable cable module. Therefore, when an electrical connection with the retractable cable module is required, a terminal board for electrically connecting the electronic device motherboard and the retractable cable module is eliminated, saving space occupied by the terminal board and reducing the space required for the internal cavity of the electronic device, thus contributing to a smaller size of the electronic device including the motherboard. Furthermore, placing the electronic components on the side of the main substrate facing away from the contact spring terminals or conductive annular grooves avoids the need for larger contact spring terminals to contact the retractable cable module when there are larger electronic components. This simplifies the design of the contact spring terminal size and structure. Moreover, the elastic deformation of the contact spring terminals may cause localized stress concentration on the main substrate; the facing away arrangement disperses the mechanical load, reducing the probability of damage to the solder joints of electronic components.

[0038] Electronic devices refer to devices or apparatuses that utilize electronic technology to achieve specific functions. Their core characteristic is the processing and manipulation of electrical signals through electronic circuits (such as integrated circuits and semiconductor components). Common electronic devices include chargers, smartphones, televisions, stereos, and headphones. With the continuous development of electronic devices, ongoing research is needed not only in their functionality but also in their miniaturization.
[0039] Many electronic devices have a motherboard, which serves as a physical carrier and connects core components such as the CPU (Central Processing Unit), memory, graphics card, and hard drive through slots and interfaces. The structure of the motherboard affects the overall size of the electronic device. This application aims to reduce the size of electronic devices by improving the motherboard structure. To this end, this application provides an electronic device motherboard. Electronic devices using this motherboard can eliminate the need for terminal boards, thereby reducing the space occupied by the internal cavity of the electronic device and thus helping to reduce the size of the electronic device including the motherboard.
[0040] The electronic device motherboard of this application embodiment can be applied to any electronic device that needs to use a motherboard, including but not limited to chargers, smartphones, walkie-talkies, satellite phones, routers, laptops, desktop computers, tablets, printers, scanners, copiers, televisions, audio equipment, headphones, projectors, cameras, camcorders, smartwatches, fitness trackers, smart speakers, smart door locks, thermostats, etc.
[0041] Below, refer to Figures 1 to 16 Some embodiments of this application will be described in detail.
[0042] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting each other includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figures 1 to 16In the illustrated embodiments, the first direction, the second direction, and the third direction are given as examples where they intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as follows... Figures 1 to 5 , Figures 8 to 12 As shown by the arrows in the diagram, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction.
[0043] The first aspect of this application provides an electronic device motherboard 2, such as... Figures 1 to 5 As shown, the electronic device motherboard 2 includes a main substrate 21, electronic components 20, and contact spring terminals 22 or conductive annular grooves 621. The electronic components 20 are located on one side of the main substrate 21; the contact spring terminals 22 or conductive annular grooves 621 are located on the other side of the main substrate 21. The contact spring terminals 22 or conductive annular grooves 621 are used for sliding electrical connection with the telescopic wire module 6.
[0044] For example, the contact spring terminal 22 is disposed on the side of the main substrate 21 facing away from the electronic component 20.
[0045] For example, a conductive annular groove 621 is provided on the side of the main substrate 21 facing away from the electronic component 20.
[0046] Electronic components 20 disposed on the main substrate 21 include, but are not limited to, resistors, capacitors, inductors, semiconductor elements, sensors, etc.
[0047] For example, the main substrate 21 may be, but is not limited to, a printed circuit board.
[0048] The contact spring terminal 22 and the conductive annular groove 621 serve as an electrical connection structure, allowing the electronic device motherboard 2 to be directly slidably electrically connected to the retractable cable module 6. This eliminates the need for a terminal board for electrically connecting the electronic device motherboard 2 and the retractable cable module 6, saving space and reducing the footprint of the internal cavity of the electronic device, thus contributing to a smaller overall size of the electronic device, including the motherboard. Furthermore, placing the electronic component 20 on the side of the main substrate 21 facing away from the contact spring terminal 22 or the conductive annular groove 621 avoids the need for a larger contact spring terminal 22 to contact the retractable cable module 6 when a large electronic component 20 is present. This simplifies the design of the contact spring terminal 22's size and structure. Moreover, the elastic deformation of the contact spring terminal 22 can cause localized stress concentration on the main substrate 21; its facing away from the main substrate disperses the mechanical load, reducing the likelihood of damage to the solder joints of the electronic component 20.
[0049] In some embodiments of this application, such as Figure 5 As shown, the thickness H3 of the main substrate 21 is in the range of 0.6 mm to 0.8 mm.
[0050] For example, such as Figure 5 As shown, the thickness H3 of the main substrate 21 can be, but is not limited to, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, 0.7mm, 0.71mm, 0.72mm, 0.73mm, 0.74mm, 0.75mm, 0.76mm, 0.77mm, 0.78mm, 0.79mm, and 0.8mm.
[0051] By limiting the thickness H3 of the main substrate 21 to the range of 0.6mm to 0.8mm, the thickness H3 of the main substrate 21 is relatively small, which reduces the space occupied by the electronic device motherboard 2 in the thickness direction, and facilitates the miniaturization of the electronic device 100 including the electronic device motherboard 2; and the thickness H3 of the main substrate 21 is not too small, so as to meet the size requirements for setting up and arranging circuits.
[0052] Preferably, the thickness H3 of the main substrate 21 is in the range of 0.6 mm to 0.7 mm.
[0053] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the main substrate 21 has a plurality of contact spring terminals 22 on the side away from the electronic components 20. The first end of each contact spring terminal 22 is electrically connected to the main substrate 21, and the second end of each contact spring terminal 22 has a gap with the main substrate 21.
[0054] In the embodiments of this application, "multiple" means two or more.
[0055] The first end of each contact spring terminal 22 is electrically connected to the main substrate 21, and the second end of each contact spring terminal 22 has a gap with the main substrate 21, thereby providing space for the contact spring terminal 22 to undergo elastic deformation, enabling the contact spring terminal 22 to achieve the function of elastic contact; and when the contact spring terminal 22 is in contact with the telescopic wire module 6, an electrical connection can be achieved.
[0056] In some embodiments of this application, such as Figures 3 to 5 As shown, each contact spring terminal 22 includes an electrical contact point 220 for electrical connection with the telescopic wire module 6, and the distance H2 between the electrical contact point 220 and the main substrate 21 is in the range of 2mm to 3mm.
[0057] For example, see Figure 5The point of the contact spring terminal 22 that is farthest from the main substrate 21 is called the electrical contact point 220. The distance H2 between the electrical contact point 220 and the main substrate 21 can also be considered as the dimension of the overall structure including the contact spring terminal 22 and the terminal mounting part 23 on which the contact spring terminal 22 is mounted in the thickness direction of the main substrate 21.
[0058] For example, the distance H2 between the electrical contact 220 and the main substrate 21 can be, but is not limited to, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3mm.
[0059] Thus, by setting the distance H2 between the electrical contact 220 and the main substrate 21 to be in the range of 2mm to 3mm, the gap between the main substrate 21 and the retractable cable module 6 is relatively small when the contact spring terminal 22 is electrically connected to the retractable cable module 6, which further helps to reduce the space occupied, thereby facilitating the miniaturization of the electronic device 100 including the electronic device motherboard 2; and the distance between the electrical contact 220 and the main substrate 21 is not too small to reduce the risk of short circuit, and surface mount components such as resistors and capacitors can also be arranged in the space between the main substrate 21 and the retractable cable module 6, making reasonable use of space.
[0060] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the plurality of contact spring terminals 22 include a first power terminal 221, a second power terminal 222, a first data terminal 223, a second data terminal 224, and a third data terminal 225; the first data terminal 223, the second data terminal 224, and the third data terminal 225 are located between the first power terminal 221 and the second power terminal 222, and the width of the first power terminal 221 and the second power terminal 222 is greater than the width of the first data terminal 223, the second data terminal 224, and the third data terminal 225.
[0061] Understandably, the first power terminal 221 and the second power terminal 222 are used to transmit current. The first data terminal 223, the second data terminal 224, and the third data terminal 225 are used to transmit digital or analog signals.
[0062] By placing the first data terminal 223, the second data terminal 224, and the third data terminal 225 between the first power terminal 221 and the second power terminal 222, a symmetrical and compact structure is formed, reducing the overall space occupied and facilitating integration on the main substrate 21. Furthermore, the widened design of the first power terminal 221 and the second power terminal 222 improves current carrying capacity, reduces resistance and heat generation, and enhances the stability of high-current transmission. Meanwhile, the narrower first data terminal 223, second data terminal 224, and third data terminal 225 meet signal transmission requirements and adapt to the low-interference requirements of high-frequency signals.
[0063] In some embodiments of this application, the widths of the first power terminal 221 and the second power terminal 222 are in the range of 0.48 mm to 0.65 mm.
[0064] For example, the width of the first power terminal 221 can be 0.48mm, 0.49mm, 0.50mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, or 0.65mm. The width of the second power terminal 222 can be 0.48mm, 0.49mm, 0.50mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, or 0.65mm.
[0065] Thus, by setting the width of the first power terminal 221 and the second power terminal 222 to be in the range of 0.48mm to 0.65mm, the current carrying requirements of conventional power transmission can be met, while avoiding the risk of increased resistance and overheating caused by excessive narrowness.
[0066] In some embodiments of this application, the widths of the first data terminal 223, the second data terminal 224, and the third data terminal 225 are in the range of 0.28 mm to 0.45 mm.
[0067] For example, the width of the first data terminal 223 can be, but is not limited to, 0.28mm, 0.29mm, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, or 0.45mm. The width of the second data terminal 224 can be, but is not limited to, 0.28mm, 0.29mm, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, or 0.45mm. The width of the third data terminal 225 may be, but is not limited to, 0.28mm, 0.29mm, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, and 0.45mm.
[0068] Thus, by setting the width of the first data terminal 223, the second data terminal 224 and the third data terminal 225 to be in the range of 0.28mm to 0.45mm, the width is narrower, which can adapt to the requirements of high frequency signal transmission, reduce parasitic capacitance and crosstalk, improve the impedance matching performance of the data terminals, and also reduce the space occupied, which is conducive to the compactness of the contact spring terminals 22.
[0069] In some embodiments, such as Figure 4 and Figure 5 As shown, the electronic device motherboard 2 also includes a terminal mounting part 23. The terminal mounting part 23 is connected to the side of the main substrate 21 facing away from the electronic components 20. The terminal mounting part 23 is equipped with contact spring terminals 22. The terminal mounting part 23 has a flat structure and its thickness direction is consistent with the thickness direction of the main substrate 21.
[0070] For example, the terminal mounting portion 23 is made of plastic, which may be, but is not limited to, flame-retardant polycarbonate or polybutylene terephthalate. The plastic body can effectively isolate adjacent contact spring terminals 22, prevent short circuits or leakage, and has flame-retardant properties.
[0071] By providing the terminal mounting portion 23, the contact spring terminal 22 is mounted on one side of the main substrate 21. Furthermore, by designing the terminal mounting portion 23 as a flat plate, the space occupied by the terminal mounting portion 23 itself is reduced. Additionally, the thickness direction of the terminal mounting portion 23 is aligned with the thickness direction of the main substrate 21, which reduces the overall thickness of the structure formed by the terminal mounting portion 23 and the main substrate 21, thereby reducing the size of the electronic device motherboard 2 and facilitating the miniaturization of the electronic device 100 including the electronic device motherboard 2.
[0072] For example, each terminal mounting part 23 is equipped with a plurality of contact spring terminals 22, and all contact spring terminals 22 installed in the same terminal mounting part 23 are distributed sequentially at intervals along the width direction of the contact spring terminals 22 and are arranged parallel to each other.
[0073] In some embodiments of this application, such as Figure 4 As shown, the terminal mounting portion 23 has five insertion slots arranged at intervals. The two outermost insertion slots are for inserting the first power terminal 221 and the second power terminal 222, respectively. The three middle insertion slots are for inserting the first data terminal 223, the second data terminal 224, and the third data terminal 225. The insertion slots extend through the main substrate 21 in a direction intersecting the thickness direction. The first and second ends of each contact spring terminal 22 extend from the two ends of their corresponding insertion slots. This reduces the possibility of contact between adjacent contact spring terminals 22, thereby reducing the probability of mutual interference between the contact spring terminals 22.
[0074] In some embodiments of this application, the thickness H1 of the terminal mounting portion 23 is in the range of 0.4 mm to 0.6 mm.
[0075] For example, the thickness H1 of the terminal mounting portion 23 can be, but is not limited to, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, 0.45mm, 0.46mm, 0.47mm, 0.48mm, 0.49mm, 0.5mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, or 0.6mm.
[0076] Thus, by setting the thickness H1 of the terminal mounting portion 23 to be in the range of 0.4mm to 0.6mm, the thickness H1 of the terminal mounting portion 23 is set to be relatively thin, reducing the space occupied, and also meeting the size requirements for installing the contact spring terminal 22.
[0077] In some embodiments of this application, such as Figure 4 and Figure 5As shown, a plurality of terminal mounting portions 23 are mounted on one side of the main substrate 21. Each terminal mounting portion 23 is equipped with a first power terminal 221, a second power terminal 222, a first data terminal 223, a second data terminal 224 and a third data terminal 225.
[0078] This configuration improves the reliability of the electrical connection between the electronic device motherboard 2 and the retractable cable module 6.
[0079] For example, such as Figure 4 and Figure 5 As shown, the terminal mounting portion 23 is fixed to the surface of the main substrate 21 facing away from the electronic components 20. The contact spring terminal 22 is a bent strip structure. One end of the contact spring terminal 22 is inserted into the terminal mounting portion 23 and connected to the printed circuit in the main substrate 21. The other end extends away from the main substrate 21 towards the terminal mounting portion 23, bends, and then extends towards the main substrate 21, so that part of the contact spring terminal 22 forms an approximately V-shaped structure. The bend of this approximately V-shaped structure is the electrical contact point 220, which elastically abuts against the electrical adapter plate 62. The terminal mounting portion 23 is equipped with a plurality of contact spring terminals 22, and the main substrate 21 is equipped with a plurality of contact spring terminals 22.
[0080] A second aspect of this application provides an electronic device 100, such as... Figures 3 to 5 As shown, the electronic device 100 includes the aforementioned electronic device motherboard 2 and retractable cable module 6. The retractable cable module 6 can pull out or retract the data cable 5. The contact spring terminal 22 or conductive annular groove 621 of the electronic device motherboard 2 is slidably electrically connected to the retractable cable module 6.
[0081] For example, the electronic device motherboard 2 has a contact spring terminal 22, and the telescopic cable module 6 has a conductive annular groove 621 that elastically contacts the contact spring terminal 22, thereby realizing a sliding electrical connection between the electronic device motherboard 2 and the telescopic cable module 6.
[0082] For example, the electronic device motherboard 2 has a conductive annular groove 621, and the telescopic cable module 6 has a contact spring terminal 22 that elastically contacts the conductive annular groove 621, thereby realizing a sliding electrical connection between the electronic device motherboard 2 and the telescopic cable module 6.
[0083] In some embodiments of this application, such as Figures 1 to 3 As shown, the electronic device 100 also includes a connector 3, which is electrically connected to the main substrate 21 and is used for electrical connection to a power source.
[0084] The connector 3 is a mechanical structure used to connect with the power supply. After the connector is plugged in, the two are electrically connected, so that the current in the power supply can be electrically connected through the connector 3, the electronic device motherboard 2 and the telescopic cable module 6 in sequence.
[0085] In some embodiments of this application, such as Figure 3 As shown, the connector 3 includes a pin mounting base 31 and a pin 32 mounted on the pin mounting base 31. The pin mounting base 31 is connected to the housing 1. One end of the pin 32 is electrically connected to the main substrate 21, and the other end is used to connect with a power supply.
[0086] For example, pin 32 is fixedly connected to pin mounting base 31.
[0087] For example, the pin 32 is movably connected to the pin mounting base 31. This movable connection can be either a rotational connection or a sliding connection. The pin 32 can switch between an extended position and a retracted position. When the pin 32 is in the extended position, its extension direction is perpendicular to the outer surface of the pin mounting base 31, allowing it to be inserted into a power socket for charging. When the pin 32 is in the retracted position, it is housed in a receiving groove on the outer surface of the pin mounting base 31, reducing the space occupied by the pin 32 and further reducing the space occupied by the electronic device 100. The movable connection structure between the pin 32 and the pin mounting base 31 can refer to existing technology and will not be described in detail here.
[0088] In some embodiments of this application, such as Figures 1 to 3 As shown, the electronic device 100 also includes a housing 1, which has a receiving cavity inside. The electronic device motherboard 2 is fixed in the receiving cavity, and the telescopic cable module 6 is rotatably mounted on the housing 1 and at least partially received in the receiving cavity. The electronic device motherboard 2 and the telescopic cable module 6 are distributed sequentially along the first direction X.
[0089] In some embodiments of this application, such as Figure 9 As shown, the telescopic cable module 6 includes a data cable 5, a rotating wheel 61, and an electrical adapter plate 62. The data cable 5 is wound around the rotating wheel 61, which can rotate around its central axis in two opposite clockwise directions to wind or unwind the data cable 5. The electrical adapter plate 62 is connected to one end of the rotating wheel 61 along the axial direction of the rotating wheel 61. The electrical adapter plate 62 extends beyond the rotating wheel 61 radially. On the side of the electrical adapter plate 62 away from the rotating wheel 61, multiple conductive annular grooves 621 are spaced apart. The multiple conductive annular grooves 621 are in elastic contact with multiple contact spring terminals 22 of the electronic device motherboard 2.
[0090] It should be noted that the data cable 5 is wound around the outer circumference of the rotating wheel 61. The end of the data cable 5 closest to the center of the rotating wheel 61 is called the connecting end 51, and the end furthest from the center of the rotating wheel 61 is called the movable end 52. This means that the movable end 52 extends or shortens as the rotating wheel 61 unwinds or rewinds the data cable 5. The movable end 52 has a charging connector 53, which is used to connect to a device to be charged. The device to be charged is any device that needs power to maintain normal operation, and can be, but is not limited to, mobile phones, tablets, laptops, rechargeable headphones, etc.
[0091] The rotation of the rotating wheel 61 allows for the winding or unwinding of the movable end of the data cable 5. Winding facilitates storage of the electronic device 100, while unwinding allows the charging connector 53 of the data cable 5 to be pulled to a more distant location, improving operational convenience. Furthermore, the electrical adapter plate 62 is electrically connected to the mainboard 2 of the electronic device via a conductive annular groove 621, enabling its conductive function. The electrical adapter plate 62 is connected to one end of the rotating wheel 61 along its axial direction and extends radially beyond the rotating wheel 61, acting as a baffle to prevent the data cable 5 from dispersing to one side of the rotating wheel 61, improving the stability of the data cable 5's extension and retraction. The electrical adapter plate 62 also serves as an electrical connector to other modules, thus reducing the number of components, minimizing space usage, and further facilitating the miniaturization of the electronic device 100. In addition, the conductive annular groove 621 is configured as a groove, so that the electrical contact point 220 of the contact spring terminal 22 of the electronic device motherboard 2 extends into the conductive annular groove 621. The conductive annular groove 621 plays a limiting role and improves the stability of the electrical connection between the two.
[0092] For example, the connection end 51 of the data cable 5 is electrically connected to the side of the electrical adapter plate 62 where the conductive annular groove 621 is provided, or the connection end 51 of the data cable 5 is electrically connected to the side of the electrical adapter plate 62 away from the conductive annular groove 621.
[0093] In some embodiments of this application, such as Figures 6 to 8 As shown, the electrical adapter plate 62 has an electrical connection position 622 on the side opposite to the conductive annular groove 621, and the electrical connection position 622 is electrically connected to one end of the data cable 5.
[0094] It is understandable that the electrical connection point 622 is electrically connected to the connection end 51 of the data cable 5.
[0095] For example, the electrical connection 622 is soldered to the connection end 51 of the data line 5.
[0096] This design reduces the likelihood of the data cable 5's connection end 51 contacting the conductive annular groove 621, thereby reducing the risk of a short circuit. Furthermore, by placing the electrical connection point 622 on the side facing the rotating wheel 61, the need for the data cable 5 to extend to the electrical adapter plate 62 away from the rotating wheel 61 is avoided, thus shortening the length of the data cable 5. It also eliminates the space occupied by the portion of the data cable 5 extending to the electrical adapter plate 62 away from the rotating wheel 61, further facilitating the miniaturization of the electronic device 100.
[0097] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, the electronic device 100 also includes a limiting plate 63, which is connected to the end of the rotating wheel 61 away from the electrical adapter plate 62. The limiting plate 63 extends beyond the rotating wheel 61 radially. The portion of the limiting plate 63 and the portion of the electrical adapter plate 62 extending radially beyond the rotating wheel 61 forms a winding groove 60 between the limiting plate 63 and the outer peripheral surface of the rotating wheel 61. The portion of the data cable 5 wound around the rotating wheel 61 is accommodated in the winding groove 60.
[0098] With this configuration, the limiting plate 63 acts as a baffle that prevents the data cable 5 from spreading away from the electrical adapter plate 62, thus reliably confining the data cable 5 wrapped around the outer circumference of the rotating wheel 61 within the winding groove 60 and improving the stability of the data cable 5's extension and retraction operation.
[0099] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the limiting plate 63 and the rotating wheel 61 are integrally formed, and / or, of the rotating wheel 61 and the electrical adapter plate 62, one has a plug groove 623 and the other has a plug protrusion 612. The plug protrusion 612 is inserted into the plug groove 623 and heat-fused together.
[0100] For example, such as Figure 10 As shown, the limiting plate 63 and the rotating wheel 61 are integrally formed. This improves the reliability of their connection, saves assembly steps, and increases production efficiency.
[0101] For example, such as Figure 9 As shown, of the two components, the rotating wheel 61 and the electrical adapter plate 62, one has a insertion groove 623 and the other has an insertion protrusion 612. The insertion protrusion 612 is inserted into the insertion groove 623 and heat-fused together. The rotating wheel 61 and the electrical adapter plate 62 are connected by the insertion protrusion 612 and the insertion groove 623, which improves the reliability of the connection and makes the connection operation convenient.
[0102] In some embodiments of this application, such as Figure 9 and Figure 10As shown, a receiving groove 611 is formed on the surface of the rotating wheel 61 facing the electrical adapter plate 62. One end of the data cable 5 passes through the receiving groove 611 from the outer periphery of the rotating wheel 61 and is electrically connected to the electrical connection position 622.
[0103] In this way, the receiving slot 611 can accommodate a part of the data cable 5, so that the connection end 51 of the data cable 5 is electrically connected to the electrical connection position 622 within the receiving slot 611, avoiding the connection point from being exposed, reducing the risk of the connection point being broken due to contact with other components, and also reducing the occupation of external space, which is conducive to the miniaturization of the retractable cable module 6, thereby facilitating the miniaturization of the electronic device 100 including the retractable cable module 6.
[0104] In some embodiments of this application, the orthographic projection of the electrical connection position 622 along the axial projection of the wheel 61 falls entirely within the orthographic projection range of the receiving groove 611.
[0105] This improves the adequacy of the connection between the data cable 5 connector 51 and the electrical connector 622, and also avoids the risk of short circuits caused by the exposed electrical connector 622 making electrical contact with other components.
[0106] In some embodiments of this application, such as Figure 9 As shown, the receiving groove 611 contains a resilient reset member 64 that can drive the rotating wheel 61 to wind up the data cable 5.
[0107] Optionally, the resilient reset element 64 can be made of a metallic or non-metallic material. Non-metallic materials can be, but are not limited to, polyoxymethylene.
[0108] For example, the elastic reset member 64 is connected between the housing and the rotating wheel 61. The elastic reset member 64 can apply an elastic reset force to the rotating wheel 61. The direction of the elastic reset force is opposite to the winding direction of the data cable 5 on the rotating wheel 61. The winding direction refers to the direction from the connection end 51 of the data cable 5 along the direction surrounding the rotating wheel 61 to the moving end.
[0109] Thus, with the elastic reset member 64, when the rotating wheel 61 rotates in the first clockwise direction, the movable end of the data cable 5 extends outward. After the force driving the movable end of the data cable 5 to extend outward is removed, the rotating wheel 61 can rotate in the second clockwise direction, opposite to the first clockwise direction, under the action of the elastic reset member 64, thereby winding the movable end onto the rotating wheel 61. In this way, the elastic reset member 64 enables the rotating wheel 61 to automatically wind up the movable end, eliminating the need for manual rotation of the rotating wheel 61, saving manpower, and improving the user experience. Furthermore, the rotating wheel 61 has a receiving groove 611 for accommodating the elastic reset member 64, saving the space occupied by the elastic reset member 64 within the housing's receiving cavity, and also improving the stability of the elastic reset member 64's installation.
[0110] In some embodiments of this application, the elastic reset member 64 is made of metal, and an insulating partition 65 blocks the side of the elastic reset member 64 facing the electrical adapter plate 62.
[0111] For example, the elastic reset element 64 includes, but is not limited to, a spring or a torsion spring.
[0112] For example, the insulating partition 65 may be made of, but is not limited to, plastic or polyurethane.
[0113] For example, the metal material used for the elastic reset member 64 can be, but is not limited to, carbon spring steel, alloy spring steel, stainless steel, copper alloy, and nickel-based alloy.
[0114] The elastic reset member 64 is made of metal, which improves its durability and extends its service life. Furthermore, an insulating partition 65 is provided on the side of the elastic reset member 64 facing the electrical adapter plate 62, reducing the likelihood of the elastic reset member 64 coming into contact with the electrical connection point 622 and minimizing the chance of the elastic reset member 64 affecting current transmission.
[0115] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, the insulating partition 65 is accommodated in the receiving groove 611.
[0116] This not only improves the reliability of fixing the insulating partition 65, but also reduces the space occupied by the insulating partition 65 in the accommodating groove 611, further facilitating the miniaturization of the electronic device 100.
[0117] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the receiving groove 611 includes a first groove 6111 and a second groove 6112 separated by a partition plate 6110. The partition plate 6110 extends in a circumferential direction along the central axis surrounding the rotating wheel 61. The second groove 6112 surrounds the outer periphery of the first groove 6111. The elastic reset member 64 is accommodated in the first groove 6111. One end of the data cable 5 passes through the second groove 6112 from the outer periphery of the rotating wheel 61.
[0118] For example, the first groove 6111 shares a central axis with the rotating wheel 61.
[0119] For example, the electrical connection position 622 of the electrical adapter plate 62 is opposite to the second groove 6112 in the axial direction of the roller 61.
[0120] In this way, the elastic reset component 64 and the connecting end 51 are separated, which reduces the chance of them interfering with each other and facilitates their stable installation.
[0121] In some embodiments of this application, such as Figure 9 and Figure 10As shown, the insulating partition 65 includes a main body 651, which covers the opening of the first groove 6111.
[0122] By sealing the opening of the first groove 6111 by the main body 651, the elastic reset member 64 contained in the first groove 6111 is enclosed. This not only facilitates the installation stability of the elastic reset member 64, but also completely blocks the electrical connection position 622 between the elastic reset member 64 and the electrical adapter plate 62, thereby further reducing the probability that the elastic reset member 64 will affect the current transmission.
[0123] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the insulating partition 65 also includes an extension 652 extending from the main body 651 to the outer periphery, the extension 652 covering at least a portion of the opening of the second groove 6112.
[0124] By covering at least a portion of the opening of the second groove 6112 with the extension 652, the limiting effect of the connecting end 51 within the second groove 6112 is improved, thereby enhancing the fixing stability of the connecting end 51.
[0125] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the extension 652 has a notch 653, one end of the data line 5 passes through the second groove 6112 and exits through the notch 653, and is electrically connected to a plurality of electrical connection points 622.
[0126] By setting the notch 653, the connection end 51 of the data cable 5 extends from the second slot 6112 toward the electrical adapter board 62, thereby connecting the connection end 51 to the electrical connection position 622.
[0127] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the insulating partition 65 is formed as an integral structure.
[0128] This not only improves the connection strength between the main body 651 and the extension 652, but also saves assembly steps and increases production efficiency.
[0129] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the end of the partition plate 6110 facing the electrical adapter plate 62 has a connecting protrusion 6113, and the insulating partition plate 65 has a connecting groove 654. The connecting protrusion 6113 is inserted into the connecting groove 654 and heat-fused together.
[0130] By connecting the protrusion 6113 and the connecting groove 654 through insertion and heat fusion, the partition plate 6110 and the insulating partition plate 65 are fixedly connected together. That is, the insulating partition plate 65 is fixedly connected to the rotating wheel 61, which improves the insulation barrier effect of the insulating partition plate 65.
[0131] In some embodiments of this application, such as Figures 1 to 3 As shown, the housing 1 includes a bottom shell 11, a cover 12, and a side panel 13. The bottom shell 11 and the cover 12 are aligned along the first direction X. Both the bottom shell 11 and the cover 12 have notches 14 on the same side along the second direction Y that intersects with the first direction X. The notches 14 are aligned to form an opening. The side panel 13 closes the opening. The bottom shell 11, the cover 12, and the side panel 13 together form a receiving cavity. The movable end 52 of the data cable of the telescopic cable module passes through the side panel 13 and extends out of the housing 1.
[0132] During assembly, the portion of the data cable 5 wound around the rotating wheel 61 can be assembled into the bottom shell 11. The charging connector 53 of the data cable 5 can be passed through the through hole of the side panel 13. Then, the side panel 13 can be installed into the notch 14 of the bottom shell 11. After that, the cover 12 can be assembled into the bottom shell 11 and the side panel 13 along the first direction X, so that the side panel 13 closes the notch 14 of the cover 12, thereby realizing the assembly of the shell 1. In this way, the assembly operation of the electronic device 100 can be simplified, which is conducive to improving the production efficiency of the electronic device 100.
[0133] In some embodiments of this application, such as Figure 11 As shown, the edge of the side panel 13 is formed with an insertion groove 141 and / or an insertion protrusion 131 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion protrusion 131 and / or an insertion groove 141, and the insertion protrusion 131 and the insertion groove 141 are engaged and inserted.
[0134] For example, the edge of the side panel 13 is formed with an insertion groove 141 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion protrusion 131, which engages with the insertion groove 141.
[0135] For example, the edge of the side panel 13 is formed with an insertion protrusion 131 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion groove 141, the insertion protrusion 131 and the insertion groove 141 are engaged and inserted.
[0136] For example, the edge of the side panel 13 is formed with an insertion protrusion 131 and an insertion groove 141 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion groove 141 and an insertion protrusion 131. The insertion protrusion 131 of the side panel 13 is engaged with the insertion groove 141 of the notch 14, and the insertion groove 141 of the side panel 13 is engaged with the insertion protrusion 131 of the notch 14.
[0137] In this way, the side panel 13 is connected to the bottom shell 11 and the cover 12, and the assembly operation is convenient and the connection is reliable.
[0138] In some embodiments of this application, such as Figure 11 As shown, the bottom shell 11 has a protruding rod 111 extending from one end toward the shell cover 12 along the first direction X, and the shell cover 12 has a groove (not shown in the figure) that mates with the protruding rod 111.
[0139] For example, the cover 12 is inserted into the groove and heat-fused together.
[0140] For example, the cover 12 is interference-fitted with the groove.
[0141] For example, the cover 12 is fitted with the groove through a gap and bonded to it with an adhesive.
[0142] In this way, the bottom shell 11 and the cover 12 are fixedly connected, the connection operation is convenient, and the connection reliability is high.
[0143] In some embodiments of this application, such as Figure 12 As shown, a mounting post 112 is formed on one of the two shell walls opposite each other along the first direction X of the housing 1. The mounting post 112 passes through the limiting plate 63, the rotating wheel 61, the insulating partition 65, the electrical adapter plate 62, and the electronic device motherboard 2 in sequence, and is locked by fasteners 7. The electronic device motherboard 2 is fixedly connected to the housing 1. The limiting plate 63, the rotating wheel 61, the insulating partition 65, and the electrical adapter plate 62 can all rotate around the mounting post 112. The fasteners 7 can be, but are not limited to, bolts, screws, or rivets.
[0144] For example, the mounting post 112 is integrally formed into the bottom shell 11.
[0145] In some embodiments of this application, such as Figure 12 As shown, the connector 3 and the side panel 13 are positioned opposite each other along the second direction Y.
[0146] In some embodiments of this application, such as Figure 12 As shown, the outer contour of the housing 1 has a dimension along the second direction Y that is greater than that along the third direction, and the dimension along the third direction is not less than that along the first direction X.
[0147] In some embodiments of this application, such as Figure 3 As shown, the electronic device 100 also includes a positioning component 8 disposed on the telescopic cable module 6. The positioning component 8 is configured to selectively restrict the rotation of the rotating wheel 61 or release the restriction on the rotating wheel 61, so that the length of the portion of the data cable 5 extending out of the housing 1 is fixed or the length of the portion of the data cable 5 extending out of the housing 1 is adjustable.
[0148] By setting the positioning component 8, the length of the part of the data cable 5 extending out of the housing 1 can be fixed, so as to be suitable for charging devices in different positions and modes, thereby improving charging convenience.
[0149] In some embodiments of this application, such as Figure 13 and Figure 15 As shown, the positioning component 8 includes a first positioning structure 81 connected to the telescopic line module 6 and a second positioning structure 82 connected to the housing 1. The first positioning structure 81 shares a central axis with the rotating wheel 61. The first positioning structure 81 has at least one limiting groove 811 formed on the outer peripheral surface around its central axis. One end of the second positioning structure 82 is rotatably connected to the housing 1 around a rotation central axis parallel to the central axis of the rotating wheel 61, and the other end has a limiting protrusion 821. The limiting protrusion 821 is configured to be able to engage with or disengage from the limiting groove 811, thereby limiting the rotation of the rotating wheel 61 or allowing the rotating wheel 61 to rotate.
[0150] Thus, the interaction between the limiting card protrusion 821 and the limiting card groove 811 enables the switching of the rotatable or restricted rotation of the rotating wheel 61, thereby adjusting and fixing the length of the data cable 5 extending out of the housing 1.
[0151] For example, such as Figure 13 As shown, the first positioning structure 81 is located on the side of the limiting plate 63 facing away from the rotating wheel 61 and is integrally formed with the limiting plate 63.
[0152] For example, such as Figure 13 As shown, the second positioning structure 82 has a first connecting hole 822, and the bottom shell 11 of the housing 1 has a first connecting shaft (not shown in the figure) that is engaged with the first connecting hole 822, so that the second positioning structure 82 is rotatably connected to the bottom shell 11 around the first connecting shaft.
[0153] In some embodiments of this application, such as Figures 13 to 15As shown, the positioning component 8 also includes a third positioning structure 83. The third positioning structure 83 is configured to limit the second positioning structure 82 to a first rotational position during the outward extension of the data line 5, and to limit the second positioning structure 82 to a second rotational position during the inward retraction of the data line 5. The line connecting the rotation center of the second positioning structure 82 and the center of the rotating wheel 61 is used as a reference line. The first rotational position is located on the positive rotation side of the reference line, and the second rotational position is located on the negative rotation side of the reference line. When the second positioning structure 82 is positioned at the first rotational position by the third positioning structure 83, the limiting protrusion 821 disengages from the limiting slot 811. When the second positioning structure 82 is positioned at the second rotational position by the third positioning structure 83, the limiting protrusion 821 engages with the limiting slot 811.
[0154] like Figure 14 As shown in the diagram, the straight dotted line L represents the reference line, the curved dotted line M represents the forward rotation direction, and the curved dotted line N represents the reverse rotation direction. "The first rotation position is located on the forward rotation side of reference line L, and the second rotation position is located on the reverse rotation side of reference line L" means that the direction of rotation from reference line L to the first rotation position is the forward rotation direction M, and the direction of rotation from reference line L to the second rotation position is the reverse rotation direction N. That is, with... Figure 14 Taking the indicated orientation as an example, the first rotation position is located to the left of reference line L, and the second rotation position is located to the right of reference line L.
[0155] Thus, as the data cable 5 extends outward, the first positioning structure 81 rotates along the reverse rotation direction N with the rotating wheel 61, and the second positioning structure 82 rotates along the forward rotation direction M. When it is positioned at the first rotation position by the third positioning structure 83, the limiting card protrusion 821 disengages from the limiting card groove 811. Then, the second positioning structure 82 allows the first positioning structure 81 to continue rotating along the reverse rotation direction N, thereby allowing the rotating wheel 61 to rotate. As a result, the data cable 5 wrapped around the rotating wheel 61 can continue to extend outward, so that the length of the part of the data cable 5 extending out of the housing 1 continues to increase. When the length of the data cable 5 extending out of the housing 1 reaches a suitable level, the outward extension of the data cable 5 is stopped, and the data cable 5 turns inward to retract. The first positioning structure 81 rotates along the forward rotation direction M with the rotating wheel 61, and the second positioning structure 82 rotates along the reverse rotation direction N. When it rotates to the second rotation position where it is positioned by the third positioning structure 83, the limiting protrusion 821 engages with the limiting groove 811. The second positioning structure 82 then restricts the rotation of the first positioning structure 81, thereby restricting the rotation of the rotating wheel 61 along the forward rotation direction M, so that the data cable 5 no longer continues to retract, thus fixing the length of the data cable 5 extending out of the housing 1 that is wrapped around the rotating wheel 61.
[0156] In some embodiments of this application, such as Figures 13 to 15As shown, the third positioning structure 83 is configured to also limit the second positioning structure 82 to a third rotation position during the outward extension of the data line 5, and to limit the second positioning structure 82 to a fourth rotation position during the inward retraction of the data line 5. The third rotation position is located on the positive rotation side of the reference line, and the fourth rotation position is located on the negative rotation side of the reference line. When the second positioning structure 82 is positioned in the third rotation position or the fourth rotation position by the third positioning structure 83, the limiting protrusion 821 disengages from the limiting slot 811.
[0157] by Figure 14 Taking the indicated orientation as an example, the third rotation position is located to the left of reference line L, and the fourth rotation position is located to the right of reference line L. It can be understood that because the limiting protrusion 821 of the second positioning structure 82 in the second rotation position engages with the limiting groove 811, while the limiting protrusion 821 of the second positioning structure 82 in the fourth rotation position disengages from the limiting groove 811, the angle between the second rotation position and reference line L is smaller than the angle between the fourth rotation position and reference line L.
[0158] With this configuration, as the data cable 5 extends outward, the first positioning structure 81 rotates along the counter-rotation direction N with the rotating wheel 61, and the second positioning structure 82 rotates along the forward rotation direction M. When it rotates to the third rotation position where it is positioned by the third positioning structure 83, the limiting protrusion 821 disengages from the limiting groove 811. The second positioning structure 82 then allows the first positioning structure 81 to continue rotating along the counter-rotation direction N, thereby allowing the rotating wheel 61 to rotate. Consequently, the data cable 5 wound around the rotating wheel 61 can continue to extend outward, increasing the length of the portion of the data cable 5 extending out of the housing 1. When the outward extension of the data cable 5 stops and it turns inward to retract, the first positioning structure 81 rotates along the forward rotation direction M with the rotating wheel 61, and the second positioning structure 82 rotates along the counter-rotation direction N. During the rotation to the fourth rotation position where it is positioned by the third positioning structure 83, the limiting protrusion 821 remains disengaged from the limiting groove 811, allowing the data cable 5 to retract continuously until it is fully wound back to the bottom. Therefore, after using electronic device 100, the data cable 5 can be quickly rolled up, improving ease of use.
[0159] In some embodiments of this application, such as Figures 13 to 15As shown, the second positioning structure 82 has a first locking block 823 and a second locking block 824. The third positioning structure 83 is rotatably connected to the housing 1. The outer periphery of the third positioning structure 83 has multiple first locking slots 831 and multiple second locking slots 832. The multiple first locking slots 831 and multiple second locking slots 832 are circumferentially distributed around the rotation center axis of the third positioning structure 83 and are alternately arranged. The radial depth of the first locking slot 831 along the third positioning structure 83 is less than the radial depth of the second locking slot 832 along the third positioning structure 83. The shape of the first locking slot 831 matches the shape of the first locking block 823, and the shape of the second locking slot 832 matches the shape of the second locking block 824. The shapes are adapted to each other. The first locking block 823 can be engaged in the first locking slot 831 or the second locking slot 832, and the second locking block 824 can be engaged in the first locking slot 831 or the second locking slot 832. When the first locking block 823 is engaged in the first locking slot 831, the second positioning structure 82 is limited to the first rotation position. When the second locking block 824 is engaged in the first locking slot 831, the second positioning structure 82 is limited to the second rotation position. When the first locking block 823 is engaged in the second locking slot 832, the second positioning structure 82 is limited to the third rotation position. When the second locking block 824 is engaged in the second locking slot 832, the second positioning structure 82 is limited to the fourth rotation position.
[0160] Thus, during the outward extension of the data cable 5, when the first locking block 823 engages with the first locking groove 831, the second positioning structure 82 is limited to the first rotation position, and the data cable 5 can continue to extend outward. During the process of the data cable 5 stopping its extension and turning inward to retract, the second positioning structure 82 rotates along the reverse rotation direction N until the second locking block 824 engages with the first locking groove 831. Since the groove depth of the first locking groove 831 is shallow and the length of the second locking block 824 is long, the angle that the second positioning structure 82 rotates relative to the reference line L in the reverse rotation direction N is relatively small. The limiting locking protrusion 821 does not disengage from the limiting locking groove 811 and engages with each other, thereby limiting the rotation of the rotating wheel 61 and realizing the limitation of the retraction of the data cable 5. If it is necessary to retract the data cable 5 once, the data cable 5 can be stretched outward again while the second locking block 824 is engaged with the first locking slot 831 (the retraction of the data cable 5 is limited). The first locking block 823 can be engaged with the second locking slot 832. Then, the stretching of the data cable 5 is stopped and it is retracted. The second positioning structure 82 will be limited to the fourth rotation position where the second locking block 824 and the second locking slot 832 are engaged. At this time, the limiting locking protrusion 821 of the second positioning structure 82 and the limiting locking slot 811 of the first positioning structure 81 will disengage from each other, and the data cable 5 will be wound up to the bottom in one go.
[0161] In some embodiments of this application, such as Figures 13 to 15 As shown, the positioning component 8 also includes an elastic reset structure 84 that applies an elastic reset force to the second positioning structure 82.
[0162] For example, the resilient reset structure 84 is made of, but is not limited to, silicone material.
[0163] Thus, after the second positioning structure 82 rotates relative to the reference line L, the elastic reset structure 84 applies an elastic reset force to the second positioning structure 82, causing the second positioning structure 82 to rotate toward the reference line L, thereby forming a mutual locking force between the second positioning structure 82 and the third positioning structure 83, thereby realizing the length adjustment of the data line 5.
[0164] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
