Description

Technical Field

[0001] The present invention relates to a mobile wireless device and an electronic device, and in particular to a mobile wireless device and an electronic device with extended functions. Background Art

[0002] In the existing scenario, when users are outdoors, they use a Mobile Wireless Fidelity (WiFi; MiFi) device to provide network connection functions, but once they return home, they will switch to connecting to the home's Consumer Premise Equipment (CPE) to use the network functions. Invisibly, the MiFi device becomes a redundant device, resulting in a low utilization rate. In addition, the known MiFi device meets the requirements of portability and low power consumption, while the known CPE meets the requirements of high power and ultra-high-speed connection capabilities, and the two are completely different in terms of requirements. Currently, the market lacks a mobile wireless device and electronic device that can improve the utilization rate of products, increase overall performance, and save economic costs.

[0003] Therefore, it is necessary to provide a mobile wireless device and an electronic device with extended functions to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a mobile wireless device and an electronic device with expansion function, which allows users to carry a lightweight MiFi device when going out, and when returning home, they can be grouped and expanded into a CPE to enjoy the top enjoyment brought by high-speed network. Through grouping and expansion, the utilization rate of the product can be improved and the overall performance can be increased, and economic expenses can be saved to solve the problem of low utilization rate of conventional MiFi devices and extra expenses caused by the need to purchase MiFi devices separately because the requirements of MiFi devices are completely different from those of CPE.

[0005] According to one embodiment of the structural aspect of the present invention, a mobile wireless device with an expansion function is provided, which is used to connect a wireless expansion device, and includes a plurality of first antennas, a wireless communication module and at least one connection port. The wireless communication module is connected to these first antennas. The at least one connection port is connected to the wireless communication module, and the at least one connection port is used to detachably connect to at least one second antenna of the wireless expansion device, so that the wireless communication module performs wireless transmission through at least a portion of these first antennas and the at least one second antenna.

[0006] According to another embodiment of the structural aspect of the present invention, an electronic device is provided, which includes a mobile wireless device with an extended function and a wireless extension device. The mobile wireless device with an extended function includes a plurality of first antennas, a wireless communication module and at least one connection port. The wireless communication module is connected to these first antennas. This at least one connection port is connected to the wireless communication module. The wireless extension device can be detachably connected to the mobile wireless device with an extended function and includes at least one second antenna. This at least one connection port of the mobile wireless device with an extended function is used to detachably connect to at least one second antenna of the wireless extension device, so that the wireless communication module can perform wireless transmission through at least a portion of these first antennas and this at least one second antenna.

[0007] Thus, the mobile wireless device and electronic device with expansion function of the present invention can be expanded into CPE by combining the mobile wireless device and the wireless expansion device, which not only allows users to use one device for multiple purposes and achieve maximum utilization, but also greatly increases the connection capacity of the wireless network.

[0107] Please also read Figure 2 , Figure 3B , Figure 4 , Figure 5B as well as Figure 6 ,in Figure 6 Draw Figure 3B A mobile wireless device 100a with extended functions Figure 5BThe wireless extension device 200a of the mobile wireless device 100a is extended to form a side view schematic diagram of the electronic device 300. When the mobile wireless device 100a with an extension function is connected to the wireless extension device 200a, the first shell 162 and the second shell 164 of the housing 160 are respectively connected to the two sides of the housing 260. At least one heat dissipation path TP is formed between the first opening 262 and the second opening 264 to dissipate the heat generated by the mobile wireless device 100a with an extension function and the wireless extension device 200a. The electronic device 300 can be upright so that the heat dissipation path TP forms a vertical channel, the first opening 262 is located at the bottom, and the second opening 264 is located at the top. When the components inside the electronic device 300 are heated, the internal air is heated to form an upward airflow, and the hot air will be discharged from the second opening 264 at the top. At this time, the first opening 262 at the bottom will take advantage of the situation to inhale the cold air outside the body, forming a chimney effect and strengthening air convection. When the heating temperature of the components is higher, the air convection speed will be faster, which is conducive to the reduction of the internal temperature of the electronic device 300.

[0108] For example, when a user is outside, he can use the mobile wireless device 100a with extended functions, which includes five first cellular antennas 112 (5G antennas) and two first WiFi antennas 114, to connect to the Internet via 5G, and then share it with other mobile devices such as mobile phones or notebook computers via WiFi. In this way, the user can use the Internet anytime and anywhere, and using WiFi connection can also reduce the power consumption of the battery 170.

[0109] When the user returns home or to the company, the mobile wireless device 100a with expansion function can be connected to the wireless expansion device 200a to expand the connection capability. During the connection process, the mobile wireless device 100a with expansion function is first turned off. After the shutdown is completed, the battery 170 and the second shell 164 are removed to separate the first shell 162 from the second shell 164, and then the battery 170 and the second shell 164 are moved to the back of the wireless expansion device 200a to charge the battery 170.

[0110] When the battery 170 and the second shell 164 are removed from the mobile wireless device 100a with expansion functions, three first connection ports 131, one second connection port 132, one third connection port 133, one fourth connection port 134 and one fifth connection port 135 are exposed, and the second heat sink 154 is also exposed for heat dissipation.

[0111] Next, the mobile wireless device 100a with expansion function is combined with the wireless expansion device 200a. Since the battery 170 and the second housing 164 have been removed and the second heat sink 154 is exposed, the internal space is extended to the entire electronic device 300, making the overall internal space larger. This enlarged internal space is more conducive to heat dissipation. Under the same power, the average temperature will drop as the space becomes larger, so there is more temperature buffer space available; in other words, under the same temperature threshold, the power of WiFi can be further increased to improve the signal coverage.

[0112] Thus, the electronic device 300 of the present invention is mainly based on the mobile wireless device 100a with expansion function, and can be expanded into CPE by connecting with the wireless expansion device 200a, which not only allows users to use one device for multiple purposes and achieve the maximum utilization rate, but also greatly increases the connection capacity of the wireless network. In addition, the expansion of the heat dissipation module 150 and the expansion heat dissipation module 250 and the increase in space can enhance the overall heat dissipation capacity, so that the electronic device 300 can further increase the transmission power, thereby increasing the coverage range and connection rate of the connection.
