[0033] With the continuous development of technology, smart terminals have become an indispensable part of people's lives. One particularly convenient function is the ability to operate car keys through smart terminals. These terminals utilize communication components installed within them to receive and transmit frequency signals from the vehicle's computer system, allowing users to operate the car key function through the smart terminal. However, prior art requires modifying the vehicle's wiring before operating the car key function through a smart terminal, which is inconvenient.

[0034] The present invention proposes an earphone charging box 100, which aims to solve the technical problem of how to improve the convenience of controlling a car with a smart terminal.

[0035] In the embodiment of the present utility model, Figures 1 to 4As shown, the earphone charging box 100 includes: a box body 10, the box body 10 has a first side wall 11 and a second side wall 12 opposite to each other, the first side wall 11 is provided with a charging slot 111 for accommodating the earphone 200, the box body 10 is provided with a mounting cavity 13, the second side wall 12 is provided with a through hole 121 communicating with the mounting cavity 13; a power supply battery 20, the power supply battery 20 is installed in the mounting cavity 13; a main control board 30, the main control board 30 is installed in the mounting cavity 13 and is electrically connected to the power supply battery 20; an electrical connector 40, the electrical connector 40 is installed in the mounting cavity 13 The cavity 13 is electrically connected to the main control board 30, and the electrical connector 40 is at least partially exposed on the wall of the charging slot 111 to be electrically connected to the earphone 200 accommodated in the charging slot 111; the solar photovoltaic panel 50, the solar photovoltaic panel 50 is installed on the outer surface of the second side wall 12, and is electrically connected to the main control board 30 through the via 121; the communication module 60, the communication module 60 is installed on the main control board 30, and the communication module 60 is used to communicate with the car's vehicle system and the mobile terminal, so that the mobile terminal can control the car through the communication module 60.

[0036] In this embodiment, the headset 200 can be a wireless headset 200, such as a Bluetooth headset 200. The housing 10 is generally rectangular, but can also be cylindrical or irregularly shaped. The headset 200 can be detachably received in the charging slot 111, meaning that the headset 200 can be inserted into and removed from the charging slot 111. When the headset 200 is installed in the charging slot 111, the charging portion of the headset 200 connects or abuts against the electrical connector 40 within the charging slot 111. For example, the headset 200 includes a battery and exposed charging contacts, which are electrically connected to the battery. The electrical connector 40 includes a conductive pin, one end of which is exposed from the wall of the charging slot 111 and the other end is electrically connected to the main control board 30. When the headset 200 is installed in the charging slot 111, the charging contacts abut against the ends of the conductive pins, thereby establishing an electrical connection between the main control board 30 and the battery of the headset 200. The main control board 30 can distribute electrical energy to the earphones 200, and the power supply battery 20 can be charged by AC power to store electrical energy. When the earphone charging box 100 is working, the power supply battery 20 provides electrical energy to the main control board 30, and then the main control board 30 distributes the electrical energy to the battery of the earphones 200.

[0037] The solar photovoltaic panel 50 is a power generation device that generates direct current when exposed to sunlight. It is composed of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials (such as silicon). The solar photovoltaic panel 50 can be electrically connected to the charging circuit on the main control board 30 via conductive sheets or wires passing through vias 121. The headphone charging case 100 can be attached to the front windshield or window glass inside the vehicle. In this case, the second sidewall 12 is attached to the front windshield or window glass, and the solar photovoltaic panel 50 is exposed to sunlight through the transparent front windshield or window glass, thereby using solar energy to charge the power supply battery 20. This simplifies charging the headphone charging case 100 and saves electricity costs. After the user parks the car at a fixed location and leaves the vehicle, the user can remove the earphones 200 from the charging slot 111 for use, leaving the headphone charging case 100 inside the vehicle. The headphone charging case 100 attached to the front windshield or window glass can charge itself using solar energy, improving charging convenience.

[0038] The communication module 60 can be paired with the vehicle's onboard system and the user's mobile terminal for communication. The mobile terminal is a smart terminal, such as a mobile phone, a smart watch, a smart bracelet, or other smart devices that the user can carry with him.

[0039] The communication module 60 is used to enable wireless communication between the user's mobile terminal and the vehicle system to achieve effects such as controlling the locking and unlocking of the vehicle. The communication module 60 can communicate with the mobile terminal and the vehicle system in a variety of ways, such as Bluetooth, 3G network, 4G network, or 5G network, which are not limited here.

[0040] For example, communication module 60 can be part of a smart key system. The smart key system (PASSIVE KEYLESS ENTER), or PKE for short, utilizes RFID wireless radio frequency technology and a vehicle identification code recognition system. It utilizes a miniaturized, low-power radio frequency antenna development solution, integrates a remote control system with a keyless entry system, and utilizes traditional vehicle circuit protection to achieve a dual radio frequency system and dual anti-theft protection. In the PKE system, the vehicle acts as a base station and the parking number plate acts as a transponder, enabling two-way communication. Communication module 60 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0041] Of course, the communication module 60 can also be a component of ultra-wideband wireless carrier communication technology. Ultra-wideband (UWB) is a new ultra-wideband wireless technology that is very different from traditional communication technology. It sends and receives extremely narrow pulses of nanoseconds or less to transmit data to the vehicle, has a bandwidth of 3.1 to 10.6 GHz, and is not easily interfered with by other signals. Through the interaction between the UWB of the parking number plate and the UWB of the vehicle, the positioning algorithm can be used to identify the centimeter-level distance to the vehicle, easily achieving a quick response, allowing users to automatically control the vehicle through the parking number plate without any feeling.

[0042] By installing the communication module 60 in the box body 10, the communication module 60 can be connected to the vehicle's head unit system in a nearby manner, allowing mobile terminals such as mobile phones or smart watches to control the vehicle's communication from outside the vehicle through the communication module 60. This allows the earphone charging box 100 to be used by simply pairing the communication module 60 with the vehicle's head unit system and the mobile terminal. There is no need to modify the vehicle's head unit wiring or the mobile terminal's hardware, thus improving the convenience of controlling the vehicle. Since the earphone charging box 100 is relatively stable in the vehicle, the distance between the communication module 60 and the vehicle's head unit system can be kept relatively stable, thereby ensuring the communication signal strength between the communication module 60 and the vehicle's head unit system, thereby improving the vehicle's control effect.

[0043] Specifically, such as Figure 3 As shown, a recessed groove 122 is formed on the outer surface of the second side wall 12, and the through hole 121 is formed at the bottom of the recessed groove 122. The solar photovoltaic panel 50 is installed in the recessed groove 122. The solar photovoltaic panel 50 does not protrude from the notch of the recessed groove 122. Therefore, when the second side wall 12 is attached to the vehicle window glass or the front windshield, the solar photovoltaic panel 50 is not squeezed, thereby improving the protection effect of the solar photovoltaic panel 50.

[0044] In practical applications, such as Figure 3 and Figure 4 As shown, the portion of the second sidewall 12 surrounding the sink 122 is covered with an attachment layer 124, which is used to attach the box body 10 to an external structure. The attachment layer 124 can be a suction cup or an adhesive layer, and there is no limitation here, as long as it can stably attach the box body 10 to the front windshield or window glass of the vehicle.

[0045] For example, Figure 4As shown, the electrical connector 40 is mounted on the surface of the main control board 30 facing the first side wall 11, and the battery is mounted on the surface of the main control board 30 facing the second side wall 12, forming a heat-insulating space 14 between the battery and the second side wall 12. The heat-insulating space 14 prevents direct contact between the battery and the second side wall 12, thereby preventing heat from the solar photovoltaic panel 50 from being transferred to the battery through the second side wall 12, thereby improving the operating stability of the battery.

[0046] Specifically, the earphone charging box 100 also includes a geolocation module, which is installed in the installation cavity 13 and electrically connected to the main control board 30. The geolocation module can be a Global Positioning System (GPS) module. The geolocation module allows the user to obtain their current geographic location and the distance between the user and the car, thereby further improving the use of the earphone charging box 100.

[0047] In actual application, the earphone charging box 100 also includes an ETC module, which is installed in the installation cavity 13 and electrically connected to the main control board 30. ETC (Electronic Toll Collection), translated into Chinese as electronic non-stop toll collection, uses a dedicated short-range communication between the on-board electronic tag installed on the vehicle windshield and the microwave antenna on the ETC lane at the toll station, and uses computer networking technology to conduct back-end settlement processing with the bank, so as to achieve the purpose of vehicles passing through highway or bridge toll stations without stopping and paying highway or bridge fees. Installing the ETC module in the earphone charging box 100 can give the earphone charging box 100 an ETC function, further improving the use effect of the earphone charging box 100.

[0048] For example, Figure 1 and Figure 5 As shown, the earphone charging box 100 also includes a temperature sensor and a display screen 70. The temperature sensor is installed in the installation cavity 13, and the display screen 70 is exposed on the first side wall 11. The temperature sensor and the display screen 70 are both electrically connected to the main control board 30. The temperature sensor is used to detect the ambient temperature, and the display screen 70 is used to display the detection results of the temperature sensor. The temperature sensor can monitor the ambient temperature in the vehicle in real time, and then display the temperature on the first side wall 11 through the display screen 70, so that the user can more easily obtain the temperature conditions in the vehicle, further improving the use effect of the earphone charging box 100.

[0049] Specifically, such as Figure 4As shown, the earphone charging box 100 also includes a magnetic member installed in the installation cavity 13. The magnetic member is adjacent to the slot wall of the charging slot 111 to generate a magnetic attraction force on the earphones 200 accommodated in the charging slot 111. The magnetic member can be a magnet, and a corresponding magnetic member can be installed in the earphones 200. The magnetic member and the magnetic member attract each other, which can stably adsorb the earphones 200 in the charging slot 111, improving the installation stability of the earphones 200 in the charging slot 111 and preventing the earphones 200 from easily falling out of the charging slot 111 when the car vibrates or bumps.

[0050] In practice, the earphone charging box 100 also includes a wireless networking module installed in the mounting cavity 13. This module is electrically connected to the main control board 30 and is used to provide wireless networking for mobile devices. This wireless networking module, also known as a Wi-Fi module, can emit radio waves to connect mobile devices such as smartphones, tablets, and smartwatches to the internet. Installing the wireless networking module in the earphone charging box 100 allows the box to function as a wireless router, improving its usability.

[0051] like Figure 5 As shown, the present invention also provides an earphone kit, which includes earphones 200 and an earphone charging box 100. The specific structure of the earphone charging box 100 refers to the above embodiment. Since the present earphone kit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the earphones 200 are detachably mounted on the charging slot 111 of the earphone charging box 100 and are electrically connected to the electrical connector 40 of the earphone charging box 100.

[0052] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
