Therefore, it is particularly necessary to design a mobile solid-state hard drive with better portability. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0022] Figure 1 is a schematic block diagram of a mobile solid state hard disk according to an embodiment of the present application, such as Figure 1 As shown, the mobile solid-state hard disk includes a hard disk body 10 and a device fixing device 20.

[0023] In this embodiment, the power supply component is used to supply power to various components (including storage module, main control module, wireless signal transceiver module, etc.) inside the hard disk body under the control of the main control module. The storage module is used to store data received through the wireless signal transceiver module under the control of the main control module, or read the internally stored data and send it to the wireless signal transceiver module. The main control module is used to determine whether to write data to the storage module or read data from the storage module based on the interaction with the electronic device. The wireless signal transceiver module is used to receive data from a matching electronic device or send data to the electronic device under the control of the main control module.

Figure 2 Schematically shows the location of each device fixture on the housing 210 when the device fixture includes an adaptive telescopic bracket 220 and a magnetic element 230 or a vacuum suction cup 240. In practical applications, the location of the device fixture on the housing can be determined according to the application scenario. Figure 2 The wiring port on the lower side of the housing 210 can be used to charge the battery in the mobile solid-state hard disk. In this embodiment, the specification and type of the wiring port are not specifically limited.

[0029] The mobile solid-state hard disk provided in the embodiment of the present application realizes the wireless transmission and storage function of data through the power supply component, storage module, main control module and wireless signal transceiver module arranged in the hard disk body, and does not need to connect the hard disk body and the electronic device through USB wire, thus realizing true wireless transmission and facilitating user use. In addition, by fixing the device fixing device on the outside of the hard disk body for fixing the electronic device, the mobile solid-state hard disk can be fixed on the electronic device without damaging the electronic device, thus avoiding affecting the service life of the USB interface of the electronic device, and realizing a mobile solid-state hard disk with better portability.

[0030] In one embodiment, Figure 3 As shown, the power supply component 110 includes a battery 1110 and a power module 1120 connected to each other. The power module 1120 is connected to the storage module 120, the main control module 130 and the wireless signal transceiver module 140 respectively. It should be noted that, Figure 3 is Figure 1 The schematic block diagram obtained by refining the power supply component 110 based on , therefore, Figure 3 Zhongyu Figure 1 For the connection relationship between the parts with the same number, please refer to Figure 1 , I will not go into details here.

[0031] In this embodiment, the battery is used to provide electrical energy. The power module is used to convert the electrical energy into the voltage value required by each component. Optionally, the power module is composed of an internal coil, a DC-DC (Direct Current-Direct Current, a DC to DC power supply, which can convert electrical energy of one voltage value into electrical energy of another voltage value in a DC circuit) and an LDO (Low Dropout regulator, a low voltage difference linear regulator, an electronic component used to control the output voltage of a circuit).

[0032] In one embodiment, Figure 4 As shown, the power supply component 110 also includes an energy receiving module 1130 and an energy supply switching module 1140. The energy supply switching module 1140 is connected to the battery 1110, the energy receiving module 1130 and the power supply module 1120 respectively. It should be noted that, Figure 4 is Figure 3 The schematic block diagram obtained by refining the power supply component 110 based on , therefore, Figure 4 Zhongyu Figure 3 For the connection relationship between the parts with the same number, please refer to Figure 3 , I will not go into details here.

[0033] In this embodiment, the energy receiving module is used to obtain the electric energy required by the mobile solid-state hard disk. The energy supply switching module is used to select whether to power the power module through a battery or through an energy receiving module. When the mobile solid-state hard disk is fixedly set on an electronic device, the power module can interact with the power supply through the internal coil of the power module and the wireless coil built into the electronic device, and then convert the power into a fixed voltage value through DC-DC and LDO after obtaining the electric energy, and supply the components that need the voltage for use, so as to achieve the purpose of providing different required voltages for the entire mobile solid-state hard disk; or, when the mobile solid-state hard disk is not fixed on the electronic device or the electronic device does not have an electric energy transmitting coil, the power supply module is powered by switching to a battery through the energy supply switching module. Optionally, electronic devices include but are not limited to mobile phones, tablet computers, etc. The energy supply switching module can be a Switch (physical switch) module.

[0034] In one embodiment, the energy receiving module may include a coil. Optionally, the coil is a wireless receiving coil. In addition, in practical applications, other suitable coils may be selected according to the application scenario.

[0035] In one embodiment, when the energy receiving module includes a wireless receiving coil, Figure 5 As shown, the energy supply switching module 1140 includes a pressure sensor 410 and an energy supply switching switch 420 connected to each other. The energy supply switching switch 420 is connected to the battery 1110, the energy receiving module 1130 and the power supply module 1120 respectively. It should be noted that, Figure 5 is Figure 4 The schematic block diagram obtained by refining the energy supply switching module 1140 on the basis of FIG. Figure 5 Zhongyu Figure 4 For the connection relationship between the parts with the same number, please refer to Figure 4 , I will not go into details here.

[0036] In this embodiment, the pressure sensor is used to detect the pressure on the mobile solid-state hard disk and obtain the pressure detection result. Therefore, when the pressure detection result is not zero, the energy receiving module and the power module are connected through the power supply switching switch to obtain the electric energy required by the mobile solid-state hard disk from the electronic device through the wireless receiving coil, and the electric energy is provided to the power module. When the pressure detection result is zero, the battery and the power module are connected through the power supply switching switch to power the power module through the battery. Among them, if the pressure detection result is not zero, it means that the mobile solid-state hard disk is fixed on the electronic device. At this time, the wireless receiving coil in the mobile solid-state hard disk can obtain electric energy from the electronic device to power the mobile solid-state hard disk; if the pressure detection result is zero, it means that the mobile solid-state hard disk is not fixed on the electronic device. At this time, the mobile solid-state hard disk needs to be powered by the battery inside the mobile solid-state hard disk.

[0037] In this embodiment, by setting an energy receiving module and a power supply switching module in the mobile solid-state hard disk, the power supply method of the mobile solid-state hard disk is no longer single, and the effect of providing the mobile solid-state hard disk with the required power for operation is achieved through a battery or a wireless receiving coil.

[0038] In one embodiment, Figure 6 As shown, a distance measuring module 150 and a signal enhancement module 160 are provided in the hard disk body 10. The signal enhancement module 160 is provided between the main control module 130 and the wireless signal transceiver module 140, and the signal enhancement module 160 is respectively connected to the main control module 130, the wireless signal transceiver module 140, the distance measuring module 150 and the power supply component 110. The distance measuring module 150 is connected to the power supply component 110. It should be noted that Figure 6 is Figure 1 The schematic block diagram obtained by refining the hard disk main body 10 on the basis of Figure 6 Zhongyu Figure 1 For the connection relationship between the parts with the same number, please refer to Figure 1 , I will not go into details here.

[0039] In an alternative embodiment, if Figure 7 As shown, the distance measuring module 150 may include a pressure detection circuit 1510 and a signal conversion circuit 1520 connected to each other. The pressure detection circuit 1510 is connected to the power supply component 110, and the signal conversion circuit 1520 is connected to the signal enhancement module 160 and the power supply component 110 respectively. It should be noted that Figure 7 is Figure 6 The schematic block diagram obtained by refining the ranging module 150 based on , therefore, Figure 7 Zhongyu Figure 6 For the connection relationship between the parts with the same number, please refer to Figure 6 , I will not go into details here.

[0040] Among them, the pressure detection circuit is used to detect the pressure on the mobile solid-state hard disk and obtain the pressure detection result, so as to process the pressure detection result into a digital signal through the signal conversion circuit, and then output the digital signal to the signal enhancement module. The signal enhancement module is used to determine whether to turn on the signal enhancement mode based on the received digital signal and the preset signal threshold. When the signal enhancement mode is turned on, the wireless signal received by the wireless signal transceiver module is enhanced. The power supply component can supply power to the pressure detection circuit and the signal conversion circuit.

[0041] Optionally, the signal conversion circuit can be an ADC (Analogue to Digital Converter) conversion circuit. Exemplarily, when the size of the pressure detection result is positively correlated with the size of the digital signal, the signal enhancement module can determine not to turn on the signal enhancement mode when the digital signal is greater than or equal to a preset signal threshold; the signal enhancement module can determine to turn on the signal enhancement mode when the digital signal is less than a preset signal threshold. Among them, if the pressure detection result is large, it means that the mobile solid-state hard drive is relatively close to the electronic device (such as the mobile solid-state hard drive is fixed on the electronic device). At this time, the distance between the two is short, the path loss is small, and the external interference is also small. The quality of the transmission signal will be better, so there is no need to turn on the signal enhancement mode to ensure the signal quality. On the contrary, it is necessary to turn on the signal enhancement mode to ensure the signal quality.

[0042] Optionally, the pressure detection circuit and the signal conversion circuit may be an internal circuit of a pressure sensor, that is, the distance measurement module may include a pressure sensor whose internal circuit includes a pressure detection circuit and a signal conversion circuit.

[0043] In an optional embodiment, the ranging module may include a ranging sensor and a microprocessor connected to each other, the ranging sensor is connected to the power supply assembly, and the microprocessor is connected to the signal enhancement module and the power supply assembly respectively. In this embodiment, the ranging sensor is used to measure the distance between the mobile solid-state hard disk and the electronic device, obtain the distance detection result, and send the distance detection result to the microprocessor, and the microprocessor is used to send an enable signal to the signal enhancement module when it is determined that the distance detection result is greater than or equal to the preset distance threshold (that is, when the mobile solid-state hard disk is far away from the electronic device). At this time, the signal enhancement module is successfully enabled to turn on the signal enhancement mode. The signal enhancement module is used to enhance the wireless signal received by the wireless signal transceiver module. When the microprocessor determines that the distance detection result is less than the preset distance threshold, it does not send an enable signal to the signal enhancement module. At this time, the signal enhancement module fails to enable, and the signal enhancement module will not enhance the passing signal. The power supply assembly can power the ranging sensor and the microprocessor.

[0044] Optionally, the signal enhancement module keeps receiving instructions from the ranging module, and when receiving an enable signal from the ranging module, the signal enhancement mode is turned on. The ranging sensor includes but is not limited to an optical ranging sensor (such as a laser ranging sensor), an infrared ranging sensor, and an ultrasonic ranging sensor. The signal enhancement module can select RTS5461.

[0045] In this embodiment, by arranging a distance measurement module and a signal enhancement module in the hard disk body, the effect of adaptive distance amplification of the signal is achieved, and the stability of signal transmission can be ensured when the mobile solid-state hard disk is far away from the electronic device.

[0046] In one embodiment, Figure 4 Based on the mobile solid state hard disk shown in FIG. 1 , if the hard disk body 10 is provided with a distance measurement module 150 and a signal enhancement module 160, then Figure 8 As shown, the signal enhancement module 160 can be arranged between the main control module 130 and the wireless signal transceiver module 140, and the signal enhancement module 160 can be connected to the main control module 130, the wireless signal transceiver module 140, the ranging module 150 and the power module 1120 respectively. The ranging module 150 is connected to the power module 1120. It should be noted that, Figure 8 is Figure 4 The schematic block diagram obtained by refining the hard disk main body 10 on the basis of Figure 8 Zhongyu Figure 4 For the connection relationship between the parts with the same number, please refer to Figure 4 , I will not go into details here.

[0047] In one embodiment, Fig. 9 As shown, a printed circuit board 170 is also provided in the hard disk body 10, and the printed circuit board 170 is fixedly provided inside the hard disk body 10. The power supply component 110, the storage module 120, the main control module 130, the wireless signal transceiver module 140, the ranging module 150 and the signal enhancement module 160 are provided on the printed circuit board 170. It should be noted that Fig. 9 is Figure 6 The schematic block diagram obtained by refining the hard disk main body 10 on the basis of Fig. 9 Zhongyu Figure 6 For the connection relationship between the parts with the same number, please refer to Figure 6 , I will not go into details here.

[0048] Optionally, refer to Figure 2 The structural schematic diagram of the mobile solid-state hard drive shown in the figure can set the printed circuit board on the inner wall inside the shell. By fixing the printed circuit board on the inner wall of the shell of the hard drive body, each component is closer to the electronic device, which is conducive to better realizing the function of the mobile solid-state hard drive.

[0049] Below, Figure 8 Taking the mobile solid state drive shown in the figure as an example, the working principle of the mobile solid state drive is explained in detail:

[0050] In use Figure 8When the mobile solid-state hard disk is used as an external storage device of an electronic device, the mobile solid-state hard disk needs to be fixed on the electronic device through a device fixing device. For example, if the electronic device is a mobile phone and the device fixing device is an adaptive telescopic bracket, the mobile solid-state hard disk needs to be fixed on the back of the mobile phone using the adaptive telescopic bracket.

[0051] When the mobile solid-state hard disk is fixed on an electronic device, first of all, it is necessary to see whether the energy receiving module in the mobile solid-state hard disk can obtain electrical energy. If the energy receiving module can obtain electrical energy, the energy supply switching module connects the energy receiving module and the power supply module to supply energy to each component in the mobile solid-state hard disk with the electrical energy obtained by the energy receiving module. If the energy receiving module cannot obtain electrical energy, the energy supply switching module connects the battery and the power supply module to supply energy to each component in the mobile solid-state hard disk through the battery. The power supply module can convert electrical energy into the voltage required by each component.

[0052] When each component in the mobile solid-state hard disk operates stably based on the voltage provided by the power module, the distance measurement module detects the pressure on the mobile solid-state hard disk, obtains the pressure detection result, and processes the pressure detection result into a digital signal, thereby outputting the digital signal to the signal enhancement module. The signal enhancement module determines whether to turn on the signal enhancement mode according to the received digital signal and the preset signal threshold.

[0053] When the signal enhancement module turns on the signal enhancement mode, the wireless signal received by the wireless signal transceiver module is enhanced by the signal enhancement module and then sent by the main control module to the storage module for storage. The signal read by the main control module from the storage module is enhanced by the signal enhancement module and then transmitted by the wireless signal transceiver module.

[0054] When the signal enhancement module does not turn on the signal enhancement mode, the wireless signal received by the wireless signal transceiver module passes through the signal enhancement module and is sent by the main control module to the storage module for storage. The signal read by the main control module from the storage module passes through the signal enhancement module and is transmitted by the wireless signal transceiver module.

[0055] The mobile solid-state hard disk provided in the embodiment of the present application realizes the wireless transmission and storage function of data through the power supply component, storage module, main control module and wireless signal transceiver module arranged in the hard disk body, and does not need to connect the hard disk body and the electronic device through USB wire, thus realizing true wireless transmission and facilitating user use. In addition, by fixing the device fixing device on the outside of the hard disk body for fixing the electronic device, the mobile solid-state hard disk can be fixed on the electronic device without damaging the electronic device, thus avoiding affecting the service life of the USB interface of the electronic device, and realizing a mobile solid-state hard disk with better portability.

[0056] In summary, specific embodiments of the present subject matter have been described. Other embodiments are within the scope of the appended claims. In some cases, the actions recorded in the claims can be performed in a different order and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or sequential order shown to achieve the desired results. In some embodiments, multitasking and parallel processing can be advantageous.

[0057] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device.
