Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, specifically to a millimeter-wave-based wireless communication device. Background Technology

[0002] Millimeter-wave radar operates in the millimeter-wave band (typically referring to the 30–300 GHz frequency range, with wavelengths of 1–10 mm) and is widely used in automotive blind spot warning and monitoring. It features small size, light weight, and high spatial resolution. Based on the Doppler principle, millimeter-wave radar measures the distance, velocity, and orientation of a target object by analyzing the time difference and frequency offset between the transmitted and echoed waves. Furthermore, this characteristic allows it to accurately detect minute movements and changes in objects (including sound waves in the air). These changing electrical signals are processed and analyzed using appropriate algorithms, and can be converted into text or speech for information transmission. Millimeter waves can be used even in noisy or soundproof environments and have strong resistance to external interference. Therefore, there is a need for a millimeter-wave-based wireless communication device to meet the requirements of small size and stable communication. Utility Model Content

[0003] The purpose of this invention is to provide a millimeter-wave-based wireless communication device that solves the problems of existing communication devices being large in size, inconvenient to carry and use, and having weak anti-interference capabilities.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A millimeter-wave-based wireless communication device includes a housing and a base. The housing is connected to the base and includes an upper shell and a lower shell. The upper shell and the lower shell cover each other to form a cavity. A millimeter-wave module, a main control board, a speaker, and a microphone are disposed inside the housing. The main control board is disposed on the inner wall of the lower shell, the millimeter-wave module is disposed on the main control board, and the speaker and microphone are both disposed on the inner wall of the lower shell and face the outside of the housing. It is compact in size and has stable signal transmission and large data transmission capacity, making it convenient to use and carry.

[0006] Furthermore, the inner bottom wall of the lower shell is recessed outward to form a protrusion. A secondary control board is located inside the protrusion. The secondary control board has an earphone jack and a data interface. The earphone jack and data interface penetrate the outer wall of the protrusion to form an opening for connecting external devices, thus expanding the functionality.

[0007] Furthermore, it also includes a bracket that is detachably connected to the lower housing and secures the speaker to the lower housing. Part of the bracket extends to the protrusion to surround the sub-control panel, preventing foreign objects from entering and affecting the stable operation of the internal components.

[0008] Preferably, it also includes a card tray, which is snapped onto the main control board through the side wall of the lower shell for inserting a communication card.

[0009] Preferably, a button is also included, which is located on the lower shell and is connected to the main control board for use in starting or resetting.

[0010] Preferably, the system also includes a first antenna and a second antenna. The first antenna is attached to the inner wall of the lower shell, and the second antenna is located inside the cavity. Both the first and second antennas are connected to the main control board and can transmit signals of different wavelengths to improve communication stability.

[0011] Furthermore, the base includes a base plate, a support part, and a snap-fit ​​part. One end of the support part is connected to the base plate, and the other end is connected to the snap-fit ​​part.

[0014] Even better, when the base is placed horizontally, the angle between the upper surface of the housing and the ground is an acute angle, reducing signal attenuation.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The millimeter wave-based wireless communication device has a millimeter wave module, a main control board, a speaker and a microphone inside the housing. The millimeter wave module can transmit and receive external millimeter wave signals. The signals are converted into electrical signals and transmitted to the main control board for encoding or decoding, and then played by the speaker. Alternatively, the microphone can receive audio signals and transmit them to the main control board, which then transmits them to the millimeter wave module for transmission, thus realizing millimeter wave remote communication. The housing is mounted on a base, and the base can adjust the orientation of the millimeter wave module to ensure the directionality of signal transmission.

[0017] (2) The lower shell of the millimeter wave-based wireless communication device has a protrusion, and a secondary control board is installed inside the protrusion. A bracket is installed on the lower shell to fix the speaker and also surround the secondary control board installed inside the protrusion. The secondary control board has an earphone jack and a data interface for connecting external devices to prevent the main control board from being affected when plugged in, and also to protect the internal components.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1-6As shown, this embodiment discloses a millimeter-wave-based wireless communication device, including a housing 1 and a base 2. The housing 1 is connected to the base 2. The housing 1 includes an upper shell 12 and a lower shell 11. The upper shell 12 and the lower shell 11 cover each other to form a cavity. A millimeter-wave module 31, a main control board 32, a speaker 34, and a microphone 35 are disposed inside the housing 1. The main control board 32 is disposed on the inner wall of the lower shell 11. The millimeter-wave module 31 is disposed on the main control board 32. The speaker 34 and the microphone 35 are both disposed on the inner wall of the lower shell 11 and face the outside of the housing 1. The millimeter-wave module 31 has the following characteristics: high-speed data transmission capability, which can meet the high bandwidth requirements of high-definition audio and video; low-latency communication, which can be used for communication with low latency; strong anti-interference capability, which can still ensure communication stability in sandstorm and rain and snow weather conditions; and its overall size is small and can be built into the cavity of the housing 1.

[0028] The millimeter-wave module 31 is plugged into the main control board 32. The main control board 32 and the millimeter-wave module 31 are connected by electrical signals. The main control board 32 decodes the received electrical signals and transmits them to the speaker 34 for voice output. The main control board 32 is electrically connected to the microphone 35. The microphone decodes the received voice signals and transmits them to the millimeter-wave module 31 for external transmission, thus realizing voice transmission. The main control board 32 is also equipped with a 4G communication module.

[0029] Preferably, there are two microphones 35, which are respectively located on both sides of the upper part of the housing 1 to ensure the quality of sound pickup.

[0030] Furthermore, the inner bottom wall of the lower shell 11 is recessed outward to form a protrusion 13. A secondary control board 33 is provided in the protrusion 13. The secondary control board 33 is provided with an earphone jack 322 and a data interface 321. The earphone jack 322 and the data interface 321 penetrate the outer wall of the protrusion 13 to form an opening. The secondary control board 33 is used to exchange data and transmit information with external devices. The secondary control board 33 is separate from the main control board 32 to prevent the secondary control board 33 from affecting the stability of the main control board 32.

[0031] Furthermore, it also includes a bracket 341, which is detachably connected inside the lower housing 11 and fixes the speaker 34 to the lower housing 11. Part of the bracket 341 extends to the protrusion 13 to surround the sub-control board 33. The bracket 341 separates the sub-control board 33 to prevent foreign objects from entering through the interface on the sub-control board 33 and affecting the normal operation of the main control board 32, thus improving the stability of use. The lower housing 11 wall close to the speaker 34 is provided with multiple sound holes 121 for sound wave transmission.

[0032] Preferably, it also includes a card tray 37, which is snapped onto the main control board 32 through the side wall of the lower shell 11. A sealing ring is provided on the outer wall of the card tray 37 to prevent foreign objects from entering through the hole in the lower shell 11, thus ensuring the stability of the internal components. The card tray 37 can carry a telephone communication card for accessing public communication networks for communication.

[0033] Preferably, it also includes a button 39, which is disposed on the lower shell 11 and is connected to the main control board 32. The button 39 is made of flexible material and is used for reset or restart.

[0034] Preferably, it also includes a first antenna 36 and a second antenna 38. The first antenna 36 is attached to the inner wall of the lower shell 11, and the second antenna 38 is disposed in the cavity. Both the first antenna 36 and the second antenna 38 are connected to the main control board 32. The first antenna 36 is a flexible 4G antenna that can be attached to the inner wall of the lower shell 11 for 4G communication. The second antenna 38 is a coil antenna.

[0035] Furthermore, the base 2 includes a base plate 21, a support part 22, and a snap-fit ​​part 23. One end of the support part 22 is connected to the base plate 21, and the other end is connected to the snap-fit ​​part 23. The snap-fit ​​part 23 is inserted into the bottom of the lower shell 11 to form a snap-fit ​​connection. The support part 22 is used to support the shell 1. The base plate 21 can improve the stability of placement and can also be glued to the surface of the object for easy placement and use. The snap-fit ​​part 23 is detachably connected to the shell 1, making it convenient to use and store.

[0036] Furthermore, the locking part 23 includes a first locking block 231 and a second locking block 232. The bottom wall of the lower shell 11 is provided with two locking grooves 131. The first locking block 231 and the second locking block 232 are respectively slidably locked into the locking grooves 131. The first locking block 231 slides into the locking groove 131 to limit the direction during connection. The part of the second locking block 232 that extends into the locking groove 131 abuts against the lower shell 11 to limit the relative sliding of the shell 1 and the base 2.

[0037] Preferably, the support portion 22 is configured in a curved shape, which improves the aesthetics of the placement and is suitable for transmitting signals outward.

[0038] More preferably, when the base 2 is placed horizontally, the angle between the upper surface of the housing 1 and the ground is an acute angle. More specifically, when the base 2 is placed on a horizontal surface, the housing 1 faces the sky at 45°, so that the signal is transmitted directly towards the air and is less likely to hit the ground and be attenuated.

[0039] The working process of this millimeter-wave-based wireless communication device is as follows:

[0040] Install the housing 1 onto the base 2, place the base 2 on the ground, and activate the wireless communication device to directly emit a sound signal. The sound signal is received by the microphone 35 and transmitted to the main control board 32, where it is encoded into an electrical signal. The electrical signal is then transmitted to the millimeter-wave module 31, converted into millimeter waves, and transmitted outward. The external millimeter-wave signal is received by the millimeter-wave module 31, converted into an electrical signal, and transmitted to the main control board 32. The main control board 32 decodes the electrical signal and transmits it to the speaker 34, which then emits a sound signal, thus completing the voice communication.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
