Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, and in particular to a charging port lighting device and an electric bicycle. Background Technology

[0002] Two-wheeled and three-wheeled electric vehicles, with their advantages of flexibility, convenience, and low energy consumption, have become the core mode of transportation for short- and medium-distance travel for many consumers. In daily use, charging is a crucial step in ensuring the normal operation of electric vehicles. Most users charge in the evening or at night, but due to limited lighting conditions in their living environment, charging areas are often dimly lit and lack visibility, making it difficult for users to accurately determine the alignment of the plug and charging port. This not only requires repeated attempts, extending the operation time, but also may damage the internal structure of the plug or charging port due to incorrect insertion, or even lead to accidental contact with live parts during plugging and unplugging due to poor visibility, posing certain safety hazards. While electric vehicles on the market are constantly being optimized in terms of functional design, such as improving range and shock absorption performance, there is still no effective solution for the lighting assistance needed for nighttime charging. Existing products either rely entirely on external ambient light sources or only have lights on the front or rear of the vehicle for driving warning, failing to provide targeted lighting for the charging port area. This results in a poor charging experience for users in low-light environments. These problems have become typical pain points affecting the convenience and safety of electric vehicle use, urgently requiring solutions through targeted structural design. Utility Model Content

[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] One embodiment of this utility model provides a charging port lighting device; wherein, as shown in the figure Figure 1 As shown, the charging port includes a charging socket 120 and a flip cover 110 hinged to the edge of the charging socket 120. The flip cover 110 can be rotated away from the charging socket 120 to a first position, in which the charging socket 120 is open. The flip cover 110 can also be rotated towards the charging socket 120 to a second position, in which which the charging socket 120 is closed. Normally, the flip cover 110 remains in the second position to seal the charging socket 120 and prevent moisture and dust from entering the charging socket 120. Only when charging the electric vehicle is required will the user switch the flip cover 110 from the second position to the first position.

[0027] Furthermore, in this embodiment, the charging socket 120 includes a base 121 and a wiring terminal 122 disposed on the base 121; the flip cover 110 is hinged to the base 121, and preferably, an elastic element such as a V-shaped spring can be disposed between the flip cover 110 and the base 121 so that the flip cover 110 can be held in the second position.

[0028] like Figure 1 and Figure 2 As shown, the charging port lighting device provided in this embodiment of the present invention includes: a lighting element 210 and a sensing element 220; the sensing element 220 and the lighting element 210 are electrically connected; the lighting element 210 is fixedly disposed on the inner surface of the flip cover 110; the sensing element 220 is used to sense the position information of the flip cover 110; when the sensing element 220 senses that the flip cover 110 is in the second position, the lighting element 210 is in the off state; when the sensing element 220 senses that the flip cover 110 is switched from the second position to the first position, the lighting element 210 is turned on for a first preset time and then turned off after the first preset time, and the light emitted by the lighting element 210 can be aligned with the charging socket 120.

[0029] The position of the flip cover 110 is sensed by the sensor element 220. When the flip cover 110 switches from the second position to the first position, the lighting element 210 automatically turns on, solving the problem of having to find an additional light source or blindly search for it when charging at night in the prior art, making the operation smoother. The lighting element 210 is fixed to the inner surface of the flip cover 110, thereby protecting the lighting element 210 and preventing it from being exposed to the external environment for a long time, which would affect its service life. The lighting element 210 turns off after a first preset time, which can prevent the lighting element 210 from being "always on" during the charging of electric vehicles, thus improving the service life of the lighting element 210.

[0030] Preferably, in this embodiment, the charging port lighting device is powered by the electric vehicle's power supply. When the user is charging the electric vehicle, it is rare for the electric vehicle's power to be completely depleted. Moreover, the charging port lighting device consumes relatively little power. Even if the electric vehicle's power supply cannot drive the electric vehicle, it can still supply power to the charging port lighting device. Therefore, the electric vehicle's power supply can maintain a stable power supply to the charging port lighting device.

[0031] Of course, in other alternative embodiments, the charging port lighting device can also be equipped with an independent battery to power it, preventing the device from failing when the electric vehicle's power is completely depleted. Alternatively, the charging port lighting device can also be equipped with an independent battery, which is also powered by the electric vehicle's power supply. This independent battery primarily serves as a backup; normally, the charging port lighting device draws power from the electric vehicle's power supply, but when the electric vehicle's power is completely depleted, the independent battery can power it. Furthermore, preferably, the electric vehicle's power supply can also charge the independent battery, ensuring it remains fully charged.

[0032] As mentioned above, electric vehicle power supplies rarely run completely depleted; therefore, in this embodiment, it is preferable to use the electric vehicle's power supply to power the charging port lighting device. Figure 2As shown, the charging port lighting device also includes a constant current source drive module 230; the constant current source drive module 230 is integrated with the lighting element 210; the lighting element 210 is electrically connected to the power supply of the electric vehicle through the constant current source drive module 230. Under the action of the constant current source drive module 230, the power supply of the electric vehicle can provide a stable current to the lighting element 210, which helps to ensure the light emission stability and service life of the lighting element 210 and avoids light flickering or damage to the lighting element 210 due to current fluctuations; the sensing element 220 is also electrically connected to the constant current source drive module 230, and the signal of the sensing element 220 can be transmitted to the constant current source drive module 230; when the sensing element 220 senses that the flip cover 110 is in the second position, the constant current source drive module 230 controls the power supply to disconnect from the lighting element 210; when the sensing element 220 senses that the flip cover 110 switches from the second position to the first position, the constant current source drive module 230 controls the power supply to connect with the lighting element 210, and the power supply provides power to the lighting element 210.

[0033] Furthermore, such as Figure 2 As shown, the charging port lighting device also includes a timing module 240; the sensing element 220 is electrically connected to the constant current source drive module 230 through the timing module 240; the timing module 240 is used to receive the sensing information from the sensing element 220; when the sensing element 220 senses that the flip cover 110 has switched from the second position to the first position, the timing module 240 controls the constant current source drive module 230 to supply power to the lighting element 210, and after a first preset time, the timing module 240 controls the constant current source drive module 230 to stop supplying power to the lighting element 210, so that the lighting element 210 is turned off.

[0034] Optionally, the first preset time can be 30s, 45s, 60s, etc.

[0035] In other alternative implementations, the purpose of automatically turning off the lighting element 210 after a first preset time can also be achieved by setting an RC delay circuit, a mechanical delay switch, or other structures.

[0036] In other optional embodiments, the charging port lighting device can also be configured with a controller, with the sensing element 220, the controller, and the lighting element 210 electrically connected; the controller controls the lighting element 210 to turn on and off based on the sensing information from the sensing element 220. Specifically, when the sensing element 220 senses that the flip cover 110 is in the second position, the controller controls the lighting element 210 to be in the off state; when the sensing element 220 senses that the flip cover 110 has switched from the second position to the first position, the controller controls the lighting element 210 to be turned on for a first preset time, and after the first preset time, the controller controls the lighting element 210 to be turned off. Optionally, the controller can be a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, etc.

[0037] In the optional implementation of this embodiment, such as Figure 1 and Figure 2 As shown, the sensing element 220 includes a sensing element 221 disposed on the flip cover 110 and a magnetic bead 222 disposed on the charging socket 120; wherein, the magnetic bead 222 is a small magnetic element that can generate a magnetic field, and the magnetic bead 222 is disposed on the base 121 of the charging socket 120; when the flip cover 110 is in the second position, the sensing element and the magnetic bead 222 are disposed opposite to each other and form a sensing engagement, and the sensing element 221 transmits the sensing signal to the timing module 240, and the timing module 240 controls the constant current source drive module 230 to disconnect the power supply from the lighting element 210; when the flip cover 110 switches from the second position to the first position, the sensing between the sensing element 220 and the magnetic bead 222 fails, and the timing module 240 does not receive the sensing signal from the sensing element 221. At this time, the timing module 240 controls the constant current source drive module 230 to supply power to the lighting element 210.

[0038] Optionally, in this embodiment, the constant current source driver module 230 is a constant current source driver chip, and the timing module 240 is a timing chip or a timer chip.

[0039] Optionally, in this embodiment, the sensing element 221 is a Hall sensor or a reed switch; when the flip cover 110 switches between the first position and the second position, the sensing element 221 outputs a position sensing signal through the magnetic field of the sensing bead 222.

[0040] In the optional implementation of this embodiment, such as Figure 1 and Figure 2 As shown, the flip cover 110 includes a main body 111 and a lug 112 protruding from the surface of the main body 111. The main body 111 has a groove-like structure, and the lighting element 210 is disposed on the inner surface of the main body 111. The lug 112 is disposed on the side of the main body 111 and protrudes from it, facilitating the user to open the flip cover 110. Preferably, the sensor 221 is disposed within the lug 112. By providing the lug 112, not only is it convenient for the user to open the flip cover 110, but it also provides space for the installation of the sensor 221.

[0041] Furthermore, in this embodiment, the dial ear 112 is provided with a mounting groove, and the sensing element 221 can be fixed in the mounting groove by means of snap-fit ​​or adhesive.

[0042] Optionally, in this embodiment, the lighting element 210 is an LED lamp bead, which features low power consumption, small size, and high reliability. In other optional embodiments, the lighting element 210 can also be a miniature neon lamp, a miniature halogen lamp bead, etc.

[0043] In an optional embodiment of this example, a main circuit fuse and a secondary circuit fuse are connected in series between the power supply and the constant current source drive module 230; the main circuit fuse has a first protection current threshold; the secondary circuit fuse has a second protection current threshold; wherein, the second protection current threshold is less than the first protection current threshold, and if a short circuit occurs in the charging port lighting device, the secondary circuit fuse will take priority in protection.

[0044] Another embodiment of this utility model provides an electric vehicle, including the charging port lighting device described in any of the above embodiments.

[0045] Optionally, in this embodiment, the electric vehicle can be a two-wheeled electric vehicle or a three-wheeled electric vehicle.
