Description
Technical Field
[0001] This utility model belongs to the technical field of charging bases for new energy vehicles, and specifically relates to a charging base for new energy vehicles. Background Technology
[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] The charging dock for new energy vehicles is a key interface component for replenishing the electric energy of new energy vehicles. It is usually installed on the side or rear of the vehicle and has pin holes inside that match the charging gun for current transmission. It is an important bridge connecting the vehicle and the charging station, and its design directly affects the safety and convenience of charging.
[0004] Existing technologies include adding lighting to the charging dock; however, directly designing lighting on the base of the charging dock results in excessively scattered light. The charging dock's pin holes are critical connection points during charging, and the presence of foreign objects (such as dust, small stones, etc.) or abnormalities (such as bent or damaged pins) directly affects charging safety. Scattered light makes it difficult to accurately focus on the pin hole area, preventing users from clearly observing the internal conditions and increasing the risk of charging malfunctions or safety hazards caused by pin hole issues. Secondly, most current solutions use a "lighting on opening" approach, which fails to consider the varying lighting conditions in actual usage scenarios. During the day or in well-lit environments, the charging dock area is clearly visible; activating the lighting in such cases is an unnecessary waste of energy. New energy vehicles require efficient use of electrical energy; this indiscriminate lighting wastes limited power, contradicts the concept of energy conservation and emission reduction, and indirectly increases user costs. Utility Model Content
[0005] To address the aforementioned issues, this utility model provides a charging dock for new energy vehicles that avoids direct light shining into the user's eyes, thereby ensuring the charging head is accurately aligned with the pin holes during charging, making it easier for the user to observe the pin hole position. It also provides illumination for charging in darker environments, ensuring the charging plug is accurately inserted into the pin holes, and can adjust the brightness according to the ambient light, avoiding energy waste and reducing usage costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A charging base for a new energy vehicle includes a charging mounting base with a pin hole in the middle and a light sensor at one end of the pin hole; one end of the charging mounting base is hinged to one end of a hinge rod, and the other end of the hinge rod is hinged to one end of a cover plate; a light is provided in the middle of the cover plate, and both the light and the light sensor are electrically connected to a controller.
[0008] As a further technical solution, a lock head is provided at the other end of the cover plate, and a position sensor is provided on the side of the lock head. The position sensor is electrically connected to the controller, and the open and closed state of the lock head is detected by the position sensor.
[0009] As a further technical solution, guide grooves are symmetrically arranged at both ends of the pin hole, and the guide grooves are arranged on the charging mounting base.
[0010] As a further technical solution, guide blocks are provided at both ends of the lighting lamp, and the guide blocks are set on the cover plate.
[0011] As a further technical solution, power lines are laid inside the cover plate and the hinge rod.
[0012] As a further technical solution, the lighting lamp is connected to a power source via a power cord.
[0013] As a further technical solution, signal lines are arranged inside the cover plate and the hinge rod.
[0014] As a further technical solution, the position sensor is electrically connected to the controller via a signal line; the controller and the light sensor are connected via a signal line.
[0015] As a further technical solution, a lock seat is provided at one end of the pin hole, and the lock seat and the lock head are connected to close the cover plate.
[0016] As a further technical solution, the lighting lamp is detachably connected to the cover plate.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are:
[0018] This invention places a light on the cover plate, and the light is connected to the power supply via a power cord, so that the light shines from the side to illuminate the pin hole position. This can effectively avoid the light source shining directly into the user's eyes. The light is concentrated to illuminate the pin hole area, which not only avoids glaring direct light, but also allows the user to clearly observe the position and status of the pin hole, greatly reducing the difficulty of operation during docking.
[0019] After the cover is opened, the ambient light level is detected by a light sensor and fed back to the controller. The controller then controls the brightness of the lighting. When the ambient light is lower than the set value, the lighting function will automatically turn on to provide sufficient light for plugging and unplugging the charging head. This allows the pin hole area to be illuminated from the side, ensuring that even in low-light environments such as at night or in underground parking garages, users can quickly and accurately insert the charging head into the pin hole, reducing repeated attempts or interface wear caused by poor visibility and effectively avoiding energy consumption.
[0020] This invention incorporates a position sensor, which is electrically connected to a controller. When the lock head and lock seat are separated, the position sensor detects that they are in a separated state and transmits a signal to the power supply to power the lighting lamp, thus illuminating the pinhole area. When the position sensor detects that the lock head and lock seat are closed, i.e., the cover is closed, the controller transmits a closed state signal to the power supply to stop powering the lighting lamp, ultimately enabling timely illumination of the pinhole area when the cover is opened.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0025] Existing technologies include adding lighting to the charging dock; however, directly designing lighting on the base of the charging dock results in excessively scattered light. The charging dock's pin holes are critical connection points during charging, and the presence of foreign objects (such as dust, small stones, etc.) or abnormalities (such as bent or damaged pins) directly affects charging safety. Scattered light makes it difficult to accurately focus on the pin hole area, preventing users from clearly observing the internal conditions and increasing the risk of charging malfunctions or safety hazards caused by pin hole issues. Secondly, most current solutions use a "lighting on opening" approach, which fails to consider the varying lighting conditions in actual usage scenarios. During the day or in well-lit environments, the charging dock area is clearly visible; activating the lighting in such cases is an unnecessary waste of energy. New energy vehicles require efficient use of electrical energy; this indiscriminate lighting wastes limited power, contradicts the concept of energy conservation and emission reduction, and indirectly increases user costs.
[0026] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a charging socket for a new energy vehicle, such as... Figure 1 As shown, it includes a charging mounting base 1, a pin hole 2 in the middle of the charging mounting base 1, and a light sensor 12 at one end of the pin hole 2; one end of the charging mounting base 1 is hinged to one end of the hinge rod 9, and the other end of the hinge rod 9 is hinged to one end of the cover plate 4; a light lamp 8 is provided in the middle of the cover plate 4, a lock head 6 is provided at the other end of the cover plate 4, and a position sensor 11 is provided on the side of the lock head 6.
[0027] Specifically, the lighting lamp 8 is installed on the cover plate 4. The lighting lamp 8 is connected to the power supply through the power cord 10, so that the lighting lamp 8 illuminates the pin hole 2 from the side. This can effectively avoid the light source shining directly into the user's eyes. The light is concentrated to illuminate the area of pin hole 2, which not only avoids the glaring direct light, but also allows the user to clearly observe the position and status of pin hole 2, greatly reducing the difficulty of operation during docking.
[0028] Guide grooves 3 are symmetrically arranged at both ends of the pin hole 2, and the guide grooves 3 are arranged on the charging mounting base 1. Guide blocks 5 are arranged at both ends of the lighting lamp 8, and the guide blocks 5 are arranged on the cover plate 4.
[0029] Specifically, the pin hole 2 is an existing structure. When the cover plate 4 is closed, the guide block 5 is inserted into the guide groove 3. The guide groove 3 and the guide block 5 cooperate to achieve guidance, ensuring that the cover plate 4 can close in the accurate position.
[0030] A power cable 10 is installed inside the cover plate 4 and the hinge rod 9. The lighting lamp 8 is connected to the power source via the power cable 10. A signal cable 13 is installed inside the cover plate 4 and the hinge rod 9. The position sensor 11 is electrically connected to the controller via the signal cable 13.
[0031] Specifically, through the electrical connection between the controller and the position sensor 11, when the lock head 6 and the lock seat 7 are separated, the position sensor 11 detects that the lock head 6 and the lock seat 7 are in a separated state and transmits a signal to the power supply to power the lighting lamp 8, thereby illuminating the area of the pin hole 2; when the position sensor 11 detects that the lock head 6 and the lock seat 7 are closed, that is, when the cover plate 4 is closed, the controller transmits a signal of the closed state to the power supply to stop powering the lighting lamp 8, thus enabling timely illumination of the area of the pin hole 2 when the cover plate 4 is opened.
[0032] Specifically, a PLC controller can be selected as the controller, and the position sensor 11 is existing technology. The position sensor 11 is a device that can detect the position or displacement information of an object and convert it into an electrical signal. It is mainly used to determine the position, movement trajectory, or relative positional relationship of an object in space. Its core is to sense the mechanical position changes of an object (such as displacement, angle, distance, etc.) and use physical principles such as electromagnetic induction, photoelectric effect, and capacitance change to convert these physical quantities into measurable electrical signals (such as voltage, current, frequency, etc.), thereby allowing the device to obtain the position information of the object.
[0033] The controller and the light sensor 12 are connected via signal line 13.
[0034] Specifically, the ambient light level is detected by the light sensor 12 and fed back to the controller, which then controls the brightness of the lighting lamp 8. When the ambient light is lower than the set value, the lighting function will be automatically activated to provide sufficient light for plugging and unplugging the charging head. This ensures that even in low-light environments such as at night or in underground parking garages, users can quickly and accurately insert the charging head into the pin hole 2, reducing repeated attempts or interface wear caused by poor visibility and effectively avoiding energy consumption.
[0035] Specifically, the light sensor 12 is existing technology. The light sensor 12 is an electronic component that can convert light signals into electrical signals, mainly used to detect the light intensity in the environment. When light shines on the photosensitive element of the sensor (such as a photoresistor, photodiode, phototransistor, etc.), the electrical characteristics (such as resistance and current) of the photosensitive element will change with the light intensity. After circuit processing, this change can be converted into an electrical signal that can be recognized by the device, thereby realizing the sensing of light.
[0036] A lock seat 7 is provided at one end of the pin hole 2. The lock seat 7 and the lock head 6 are connected to close the cover plate 4. Specifically, the lock seat 7 and the lock head 6 are existing structures. The lock seat 7 and the lock head 6 are mechanical or electronic components used together. Their main function is to fix the charging port cover plate 4 and ensure that it remains closed when the vehicle is in motion or parked, preventing dust and rainwater from entering, while also ensuring the safety of the charging interface.
[0037] The lighting lamp 8 is detachably connected to the cover plate 4. Specifically, the lighting lamp 8 uses an LED light, which can be replaced according to usage. The brightness can be adjusted by adjusting the voltage and current.
[0038] Specifically, to ensure that the main light of the lamp 8 does not directly face the human eye, the lamp 8 is placed on the cover plate 4. In order to ensure that the pin hole area is illuminated, the angle of the lamp 8 can be set to a projection angle of 30°-60° so that the light is mainly tilted downward. Within this angle range, the light can cover the pin hole area at a suitable angle.
[0039] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
