Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, and in particular to a motherboard assembly, a programming structure, a smart host, and a smart wearable device. Background Technology

[0002] In related technologies, when a smart wearable device (such as a smartwatch or smart bracelet) experiences an unexpected interruption or software corruption during normal flashing, the system of the smart wearable device may become unusable. In such cases, forced flashing of the smart wearable device is required. Based on this, some smart wearable devices with flip-type SIM card slots have a flashing button on the motherboard. The SIM card slot can be flipped open to expose the motherboard for SIM card installation and removal, and the flashing button can be exposed to operate the smart wearable device to enter forced flashing mode.

[0003] However, for smart wearable devices that use side-insertion SIM cards, since the SIM card is inserted from the side of the smart host, the motherboard cannot be exposed when the SIM card is installed or removed. Therefore, a programming button needs to be set on the outside of the smart host to force programming the smart wearable device. However, due to the small size of the smart host, it is not possible to add a programming button on the outside of the smart host, making it difficult to force programming for side-insertion smart wearable devices.

[0043] This invention discloses a motherboard assembly, a programming structure, a smart host, and a smart wearable device. The device is installed in a mounting slot via an external fixture to electrically connect the card cover and the power connector. The low-level signal of the card cover is transmitted to the programming interface of the motherboard, enabling forced programming.

[0044] Example 1

[0045] Please refer to the following: Figure 1 and Figure 2 This is a schematic diagram of the structure of a motherboard assembly 100 provided in Embodiment 1 of the present invention. The motherboard assembly 100 includes a motherboard 10, a cover 11, and a power connector 12. The motherboard 10 has a programming interface (not shown). The cover 11 is disposed on the motherboard 10 and is grounded. A mounting groove 10a is provided between the cover 11 and the motherboard 10. The mounting groove 10a is used to install a card tray or an external fixture. The power connector 12 is disposed on the motherboard 10 and is located in the mounting groove 10a. The power connector 12 is electrically connected to the programming interface.

[0046] When a card tray is installed in the mounting slot 10a, the motherboard 10 is electrically connected to the SIM card carried in the card tray. When an external fixture is installed in the mounting slot 10a, the card cover 11 is electrically connected to the external fixture, and the connector 12 is electrically connected to the external fixture.

[0047] In this embodiment, a card cover 11 is provided on the motherboard 10, and an installation slot 10a is provided between the card cover 11 and the motherboard 10 for installing a card tray or an external fixture. A power connector 12 is provided on the motherboard 10 and electrically connected to the programming interface of the motherboard 10, and the card cover 11 is grounded. Thus, when a card tray is installed in the installation slot 10a, the motherboard 10 is electrically connected to the SIM card carried by the card tray, and the SIM card can communicate with the motherboard 10. When an external fixture is installed in the installation slot 10a, the external fixture is electrically connected to the card cover 11 and the power connector 12. At this time, the low-level signal of the card cover 11 being grounded is transmitted to the programming interface of the motherboard 10 via the power connector 12 using the external fixture. After receiving the low-level signal, the programming interface enables the motherboard 10 to enter forced programming. When this motherboard component 100 is applied to a smart wearable device, there is no need to set up an additional programming button, and the difficulty of implementing forced programming in a smart wearable device is relatively low.

[0048] Furthermore, in this embodiment, the motherboard assembly 100 is designed such that the SIM card can be used normally by installing the card tray in the mounting slot 10a. When the motherboard assembly 100 needs to be forcibly programmed, the SIM card can be removed from the mounting slot 10a, and an external fixture can be used to replace the card tray so that the programming interface of the motherboard 10 can receive a low-level signal to force programming. This achieves structural reuse. The overall structure of the motherboard assembly 100 is relatively simple, and there is no need to add additional slots or mounting slots 10a or other structures for installing external fixtures.

[0049] The cassette can be made of insulating materials, such as plastic or rubber, while the external fixture can be made of conductive materials or have conductive materials coated on its surface, such as copper, aluminum, or metal alloys.

[0050] In some embodiments, the cover 11 is provided with a connecting portion 111. When an external fixture is installed in the mounting slot 10a, the connecting portion 111 is used to abut against the external fixture to make contact and conduct. In this way, when the external fixture is installed in the mounting slot 10a, the external fixture can abut against the connecting portion 111 to make contact and conduct, thereby enabling the low-level signal of the cover 11 being grounded to be transmitted to the programming interface of the motherboard 10 via the power connector 12. After receiving the low-level signal, the programming interface can enable the motherboard 10 to enter forced programming.

[0051] For example, when an external fixture is installed in the mounting slot 10a, the connecting part 111 is also used to abut against the external fixture to fix the external fixture along the first direction x. When a card holder is installed in the mounting slot 10a, the connecting part 111 is used to abut against the card holder to fix the card holder along the first direction x, wherein the first direction x is the insertion direction of the mounting slot 10a for installing the card holder or the external fixture. Thus, when the external fixture is inserted into the mounting slot 10a along the first direction x to be installed in the mounting slot 10a, the external fixture elastically abuts against the connecting part 111. On the one hand, the connecting part 111 electrically connects the external fixture to the card cover 11, thereby enabling the low-level signal of the card cover 11 being grounded to be transmitted to the programming interface of the motherboard 10 via the power connector 12. After receiving the low-level signal, the programming interface enables the motherboard 10 to enter forced programming. On the other hand, the connecting part 111 can fix the external fixture and the card cover 11 to each other along the first direction x, thereby preventing the external fixture from shifting position during the programming process, which would cause the contact between the external fixture and the card cover 11 to fail, thus leading to programming failure. Furthermore, when the motherboard assembly 100 is not forcibly programmed, the card tray can be installed in the mounting slot 10a so that the SIM card carried in the card tray is electrically connected to the motherboard 10, thereby realizing communication between the SIM card and the motherboard 10. At this time, the connecting part 111 can fix the card tray and the card cover 11 to each other along the first direction x, thereby preventing the card tray from shifting position and causing the electrical connection between the SIM card and the motherboard 10 to fail, which would lead to the disconnection of communication between the SIM card and the motherboard 10.

[0052] In some embodiments, such as Figure 2 and Figure 3As shown, the connecting part 111 includes a first elastic part 111a and a second elastic part 111b. The first elastic part 111a and the second elastic part 111b are respectively disposed on both sides of the cover 11 along the second direction y. When the mounting groove 10a is fitted with an external fixture, the first elastic part 111a and the second elastic part 111b are used to elastically abut against both sides of the external fixture along the second direction y to fix the external fixture along the first direction x. The first elastic part 111a and / or the second elastic part 111b are used to contact and communicate with the external fixture. When the mounting groove 10a is fitted with a card holder, the first elastic part 111a and the second elastic part 111b are used to elastically abut against both sides of the card holder along the second direction y to fix the card holder along the first direction x. The second direction y is perpendicular to the first direction x. Thus, when the external fixture is inserted into the mounting slot 10a along the first direction x to be installed in the mounting slot 10a, the first elastic part 111a and the second elastic part 111b elastically abut against the two sides of the external fixture along the second direction y, respectively. On the one hand, the first elastic part 111a and / or the second elastic part 111b electrically connect the external fixture to the card cover 11, thereby enabling the low-level signal of the card cover 11 grounded to be transmitted to the programming interface of the motherboard 10 through the power connector 12. After receiving the low-level signal, the programming interface enables the motherboard 10 to enter forced programming. On the other hand, the first elastic part 111a and the second elastic part 111b can jointly clamp the external fixture, fixing the external fixture and the card cover 11 to each other along the first direction x, thereby preventing the external fixture from shifting position during the programming process, which would cause the contact between the external fixture and the card cover 11 to fail, thus leading to programming failure. Furthermore, when the motherboard assembly 100 is not forcibly programmed, the card tray can be installed in the mounting slot 10a to make the SIM card carried in the card tray electrically connected to the motherboard 10, thereby realizing communication between the SIM card and the motherboard 10. At this time, the first elastic part 111a and the second elastic part 111b are respectively elastically abutted against the two sides of the card tray along the second direction y, thereby clamping the card tray together and fixing the card tray and the card cover 11 together along the first direction x, thereby preventing the card tray from shifting position and causing the electrical connection between the SIM card and the motherboard 10 to fail, which would lead to the disconnection of communication between the SIM card and the motherboard 10.

[0053] For example, the card cover 11 includes a main body 11a and two extensions 11b. The two extensions 11b extend from two opposite edges of the main body 11a along the second direction y in a direction away from the main body 11a. The side of the two extensions 11b away from the main body 11a is connected to the motherboard 10, so that the main body 11a and the motherboard 10 are spaced apart and a mounting groove 10a is formed. The main body 11a and / or the two extensions 11b are grounded. In this way, the connection of the two extensions 11b to the motherboard 10 creates a gap between the main body 11a and the motherboard 10, thereby forming a mounting groove 10a between the main body 11a and the motherboard 10. The extensions 11b can serve as sidewalls of the mounting groove 10a, thereby protecting the card tray or external fixture installed in the mounting groove 10a, especially protecting the SIM card carried in the card tray.

[0054] Optionally, the first elastic portion 111a and the second elastic portion 111b are respectively disposed on the two extension portions 11b. In this way, by disposing the first elastic portion 111a and the second elastic portion 111b on the two extension portions 11b, when the external fixture or the card holder is installed into the mounting groove 10a, the first elastic portion 111a and the second elastic portion 111b can elastically abut against both sides of the external fixture along the second direction y or both sides of the card holder along the second direction y, and the fixing method and electrical connection method are simple and reliable.

[0055] In some embodiments, such as Figure 2 As shown, the power connector 12 is provided with a third elastic part 12a, which is electrically connected to the programming interface. When an external fixture is installed in the mounting slot 10a, the third elastic part 12a is used to elastically abut against the external fixture to make contact and conduct electricity. In this way, when the external fixture is installed in the mounting slot 10a, the external fixture can abut against the third elastic part 12a to make contact and conduct electricity with the power connector 12, thereby enabling the low-level signal of the card cover 11 grounded to be transmitted to the programming interface of the motherboard 10 via the power connector 12. After receiving the low-level signal, the programming interface can enable the motherboard 10 to enter forced programming.

[0056] For example, the connector 12 includes a fixing part 12b and a third elastic part 12a. The fixing part 12b is disposed on the motherboard 10 and located in the mounting groove 10a. The third elastic part 12a is disposed on the fixing part 12b. In this way, by fixing the part 12b on the motherboard 10, the fixing part 12b can provide a mounting position for the third elastic part 12a, and the third elastic part 12a can elastically deform relative to the fixing part 12b, thereby elastically abutting against the external fixture. The third elastic part 12a is used to realize the electrical connection between the external fixture and the programming interface of the motherboard 10.

[0057] In some embodiments, the motherboard assembly 100 further includes a spring contact group 13, which is disposed on the motherboard 10 and located in the mounting slot 10a. The spring contact group 13 has multiple spring contacts electrically connected to the motherboard 10. When a card tray is installed in the mounting slot 10a, the multiple spring contacts are used to electrically connect to the SIM card carried in the card tray. In this way, when the card tray is installed in the mounting slot 10a, the gold fingers of the SIM card carried in the card tray can elastically abut against the multiple spring contacts, and the gold fingers of the SIM card are electrically connected to the motherboard 10 using the spring contacts, thereby realizing communication between the motherboard 10 and the SIM card.

[0058] Embodiment 1 of the present invention provides a motherboard assembly 100. A card cover 11 is provided on the motherboard 10, and a mounting slot 10a is provided between the card cover 11 and the motherboard 10 for mounting a card tray or external fixture. A power connector 12 is provided on the motherboard 10 and electrically connected to the motherboard 10's programming interface, and the card cover 11 is grounded. Thus, when a card tray is installed in the mounting slot 10a, the motherboard 10 is electrically connected to the SIM card carried by the card tray, and the SIM card can communicate with the motherboard 10. When an external fixture is installed in the mounting slot 10a, the external fixture is electrically connected to the card cover 11 and the power connector 12. In this case, the external fixture transmits a low-level signal (card cover 11 grounded) to the programming interface of the motherboard 10 via the power connector 12. Upon receiving the low-level signal, the programming interface enables the motherboard 10 to enter forced programming. When this motherboard assembly 100 is applied to a smart wearable device, no additional programming button is required, and the forced programming of the smart wearable device is relatively easy.

[0059] Example 2

[0060] Please refer to the following: Figure 4 and Figure 5 This is a schematic diagram of a programming structure 200 provided in Embodiment 2 of the present invention, including an external fixture 20 and a motherboard assembly 100 in Embodiment 1. The external fixture 20 is installed in the mounting slot, the cover 11 is electrically connected to the external fixture 20, and the connector 12 is electrically connected to the external fixture 20.

[0061] In this embodiment, the card cover 11 and the power connector 12 are electrically connected by the external fixture 20, and the low-level signal of the card cover 11 is transmitted to the motherboard's programming interface to achieve forced programming.

[0062] For example, such as Figure 5As shown, the external fixture 20 is provided with a first engaging portion 20a and a second engaging portion 20b on both sides along the second direction y. The first elastic portion 111a and the second elastic portion 111b are used to elastically abut against the first engaging portion 20a and the second engaging portion 20b respectively to fix the external fixture 20 along the first direction x. The first elastic portion 111a and / or the second elastic portion 111b are in contact with the external fixture 20 and conduct electricity. One end of the external fixture 20 along the first direction x is in contact with the electrical connector 12 and conduct electricity. In this way, the first elastic part 111a and the second elastic part 111b elastically abut against the first engaging part 20a and the second engaging part 20b, respectively. On the one hand, the first elastic part 111a and / or the second elastic part 111b are used to electrically connect the external fixture 20 and the card cover 11, so that the low-level signal of the card cover 11 grounded can be transmitted to the motherboard's programming interface through the power connector 12. After the programming interface receives the low-level signal, it can force the motherboard to enter the programming process. On the other hand, the first elastic part 111a and the second elastic part 111b can jointly clamp the external fixture 20, and the first elastic part engages with the first engaging part 20a, and the second elastic part engages with the second engaging part 20b. This fixes the external fixture 20 and the card cover 11 together along the first direction x, thereby preventing the external fixture 20 from shifting position during the programming process, which would cause the contact between the external fixture 20 and the card cover 11 to fail, thus leading to programming failure.

[0063] In some embodiments, the external fixture 20 includes a plug-in portion 21 and a gripping portion 22. The plug-in portion 21 is installed in the mounting groove, and the gripping portion 22 is disposed in the plug-in portion 21. A first engaging portion 20a and a second engaging portion 20b are respectively disposed on both sides of the plug-in portion 21 along the second direction y. One end of the plug-in portion 21 along the first direction x is in contact with the electrical connector 12 for conduction. The gripping portion 22 is disposed at the end of the plug-in portion 21 opposite to the electrical connector 12 and is used for the user to hold. In this way, by using the plug-in portion 21 to provide the first engaging portion 20a and the second engaging portion, and by installing the plug-in portion 21 in the mounting groove, the first engaging portion 20a and the second engaging portion 20b can elastically abut against the first elastic portion 111a and the second elastic portion 111b, respectively. Furthermore, the gripping portion 22 can provide a gripping position for the user, thereby better applying force to install or remove the plug-in portion 21 into or from the mounting groove, reducing operational difficulty.

[0064] For example, the external fixture 20 is provided with a clearance groove 20c, which corresponds to the spring sheet assembly. In this way, by using the clearance groove 20c to avoid the spring sheet assembly, when the external fixture 20 is installed into the mounting groove, interference between the external fixture 20 and the spring sheets of the spring sheet assembly can be avoided, which would cause the spring sheets to wear and lose conductivity.

[0065] Embodiment 2 of the present invention provides a programming structure 200, which is installed in the mounting slot 10a by an external fixture 20. The external fixture 20 electrically connects the card cover 11 and the power connector 12, and transmits the low-level signal of the card cover 11 to the programming interface of the motherboard, thereby enabling forced programming.

[0066] Example 3

[0067] The present invention provides a smart host 300 in embodiment 3. The smart host 300 includes a housing 30 and a motherboard assembly 100 of embodiment 1 or a programming structure 200 of embodiment 2. The motherboard assembly 100 is disposed inside the housing 30.

[0068] Please see Figure 6 and Figure 7 As shown, this embodiment uses the smart host 300, including the motherboard component 100 of embodiment two, as an example for explanation.

[0069] In some embodiments, the periphery of the housing 30 is provided with a slot 30a communicating with the interior of the housing 30. The slot 30a is used to insert a card tray to install the card tray into the mounting slot of the motherboard assembly 100, or the slot 30a is used to insert an external fixture to install the external fixture into the mounting slot of the motherboard assembly 100. In this way, by providing a slot 30a on the periphery of the housing 30 and using the slot 30a to communicate with the mounting slot, the card tray or external fixture can be inserted into the housing 30 from the position of the slot 30a, thereby installing it into the mounting slot, realizing the electrical connection between the SIM card of the card tray and the motherboard, or realizing the electrical connection between the external fixture and the card cover and the power connector, thereby enabling the low-level signal of the card cover to be transmitted to the programming interface of the motherboard, thus realizing forced programming.

[0070] Optionally, the slot 30a is located on one side of the housing 30 along the width or length direction of the smart host 300. This embodiment provides a method of setting slots at multiple different locations on the smart host 300, which can be selected according to the actual situation, and this embodiment does not make a specific limitation.

[0071] Among them, such as Figure 7 As shown, the width direction is the same as the first direction x, and the length direction is the same as the second direction y. Furthermore, the length direction of the smart host 300 is typically the same as the length direction of the wearable component (e.g., watch strap or watch band) connected to the smart host 300. That is, when the smart host 300 is worn on the user's wrist, the length direction of the smart host 300 is approximately the same as the length direction of the user's arm, while the width direction of the smart host 300 is approximately the same as the width direction of the user's arm. In this case, the SIM card of the smart host 300 is inserted via a side-insertion method.

[0072] Embodiment 3 of the present invention provides a smart host 300, which does not require an additional programming button and can be forcibly programmed using an external fixture.
