Description

Technical Field

[0001] This utility model relates to the technical field of vehicle charging equipment, and in particular to a voice-prompt vehicle charger. Background Technology

[0002] As an on-board power conversion device, the core function of a vehicle charger is to obtain power from the vehicle's cigarette lighter socket and provide charging services for mobile terminal devices (such as smartphones and tablets). For example, many ride-hailing vehicles have low configurations, with insufficient rear charging ports, making it difficult for passengers to recharge their devices. Furthermore, the proportion of passengers carrying charging equipment on short trips is relatively low, highlighting the urgent need for standardized power supply facilities to improve the service experience. When on-board chargers are used in ride-hailing vehicles, they can provide charging services for passengers' mobile phones, effectively reducing passengers' battery anxiety.

[0003] When on-board chargers are used in ride-hailing vehicles, for the convenience of passengers, the charger body is generally located near the rear seats, such as behind the headrests of a row of seats. One end of the charger body is connected to the vehicle's cigarette lighter to draw power, and the other end is equipped with a charging cable to provide charging for passengers.

[0004] However, traditional car chargers cannot sense whether there are passengers in the vehicle. Even when there are no passengers and the charger is in an unloaded state, it still maintains full power operation, resulting in excessive static power consumption (typical value > 0.5W), which wastes the vehicle's power resources. In addition, traditional car chargers do not have a notification function. First, passengers may not know that they can charge their cars with this car charger. Second, after charging with this car charger, there are intermittent situations where passengers forget to take their phones when they get off the car, requiring extra effort to find or return the phones, which seriously affects the user experience.

[0005] Therefore, how to provide a voice-prompt-based vehicle charger that reduces power consumption and improves user experience has become a pressing technical problem. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a voice prompt-type vehicle charger, which reduces the power consumption of the vehicle charger and improves the user experience of the vehicle charger.

[0007] This utility model is implemented as follows: A voice-prompt vehicle charger, comprising:

[0019] A locator is disposed between the lower housing and the upper housing and is connected to the charging motherboard;

[0020] A communication module is located between the lower housing and the upper housing and is connected to the charging motherboard.

[0021] Furthermore, the charging module also includes:

[0022] A double-sided film;

[0023] A magnetic iron sheet is adhered to the inside of the lower housing via the double-sided adhesive film.

[0024] Furthermore, the locator is a GPS locator or a BeiDou locator.

[0025] Furthermore, the communication module is at least one of a 3G communication module, a 4G communication module, a 5G communication module, an NB-IoT communication module, a LoRa communication module, a WIFI communication module, a Bluetooth communication module, or a ZigBee communication module.

[0029] A negative electrode spring is provided on the outer side of the lower part of the power collection housing and is connected to the negative input terminal of the DC-DC module;

[0030] A positive contact is located at the bottom of the power-collecting housing and is connected to the positive input terminal of the DC-DC module;

[0031] Two USB-A ports are located on the top of the power-generating housing and are connected to the output of the DC-DC module.

[0032] Furthermore, the two USB-A ports are arranged in parallel.

[0033] Furthermore, the vehicle mount includes:

[0034] A support plate has four symmetrically arranged limiting parts on the front that match the charging module, and a ball head seat on the back.

[0035] A clip, with a ball head at one end that matches the ball head seat, the ball head being installed inside the ball head seat;

[0042] 1. The system consists of a power supply module, a spring wire, a vehicle mount, a charging module, and a charging cable. These components are connected sequentially. The charging module is mounted on the vehicle mount and includes a human body sensor and a speaker. The human body sensor is located inside the sensor window on the upper housing, while the speaker is located inside the charging module. Both the human body sensor and the speaker are connected to the charging motherboard of the charging module, with the sensing direction facing outwards. When the vehicle charger does not detect a passenger and is not charging, it can shut down unnecessary functional modules and enter a low-power mode. When the vehicle charger detects a passenger, it can play a preset usage prompt audio through the speaker. During continuous charging, if the human body sensor does not detect a passenger, it can play a preset audio message about a phone being left behind, allowing the driver to promptly remind passengers who have not yet gone far. This significantly reduces the power consumption of the vehicle charger and greatly improves the user experience.

[0043] 2. The human body sensor inside the sensor window can automatically detect the approach of a user, triggering automatic wake-up or energy-saving sleep functions to reduce standby power consumption. It can also be linked with the charging motherboard to control the start and stop of charging, improving safety.

[0044] 3. By adding two additional USB-A ports on the power module, the charging needs of multiple devices can be met.

[0045] 4. The combination structure of the ball joint and the clip supports 360° rotation, adapting to different installation environments and usage requirements.

[0046] 5. By setting the support plate to a metal support plate and setting a magnetic iron sheet inside the charging module, the charging module can be magnetically attracted to the support plate by the magnetic iron sheet, which takes into account both the convenience of taking out the charging module and the stability of its placement.

[0047] 6. By setting up a dual interface design of USB-C + Lightning, it covers the interface standards of mainstream devices, reduces the need for adapters, and greatly improves the user experience.

[0048] 7. By setting up a protective sleeve, the bending stress of the wires is effectively relieved, which is especially suitable for the high vibration conditions in the vehicle environment, thereby greatly improving the durability of the vehicle charger.

[0049] 8. By incorporating spring wires, cable tangling can be avoided, effectively improving storage convenience.

[0050] 9. By integrating the communication module and the locator, remote status monitoring and location tracking functions can be realized. Attached Figure Description

Detailed Implementation

[0062] This utility model embodiment provides a voice-prompt car charger 100, which solves the technical problems of existing car chargers failing to sense the presence of passengers in the vehicle, maintaining full power operation even when the charger is unloaded, resulting in excessive static power consumption; and traditional car chargers lacking prompt functions, which means passengers may not know they can charge their phones, and passengers may forget to take their phones when they get off the vehicle, seriously affecting the user experience. This embodiment significantly reduces the power consumption of the car charger and greatly improves the user experience.

[0063] The technical solution in this embodiment of the utility model is to solve the above problems. The general idea is as follows: By setting up a speaker 44 and a human body sensor 45 and connecting them to the charging motherboard 43, when the charging motherboard 43 detects the presence of a passenger through the human body sensor 45, it prompts the passenger to use the device through the speaker 44. When the passenger suddenly fails to detect the passenger while using the vehicle charger 100 for charging, it prompts the driver through the speaker 44 that a mobile phone has been left behind. When the human body sensor 45 does not detect a passenger and is not charging, it enters a low-power mode, thereby reducing the power consumption of the vehicle charger 100 and improving the user experience of the vehicle charger 100.
