Description

Vehicle charging system with anti-collision warning

This creation is a technology for protecting vehicle charging equipment, especially a vehicle charging system with anti-collision warning.

As the development of electric vehicle technology becomes more mature, more and more people choose to buy electric vehicles. Electric vehicles must store electricity in their on-board batteries as the energy source for electric vehicles to drive on the road. The current charging methods for electric vehicles include finding an electric vehicle charging station near the location of the electric vehicle, or An electric vehicle charging system is installed in its own parking lot to charge electric vehicles.

At present, many parking lots use mechanical parking systems, and mechanical parking systems provide parking space for vehicles by setting up a movable vehicle platform for parking. However, the vehicle platform is limited by space constraints and its size is often It can only be designed to be a size that only allows vehicles to move in and out. Therefore, the space around the vehicle platform is quite small, so that when the vehicle enters the vehicle platform, the problem of misalignment between the vehicle and the vehicle platform is likely to occur, which will cause the vehicle The tires are pressed to the edge of the carrier, making it difficult to install other equipment for electric vehicles on the vehicle carrier. Therefore, when integrating the electric vehicle charging system on the mechanical parking system, considering the space limitation of the vehicle carrier, the electric vehicle charging system can only be configured in the vehicle. At the edge of the vehicle carrier, in this configuration, the electric vehicle charging system or its components are prone to the risk of being run over or hit by the vehicle.

In view of the above-mentioned problems caused by the integration of the electric vehicle charging system into the mechanical parking system, the traditional anti-collision method usually adopts a physical anti-collision structure, that is, a solid protective structure is added in front of the electric vehicle charging system to allow the electric vehicle to collide. Before the electric vehicle charging system, it first collides with the set protection structure to avoid direct impact on the electric vehicle charging system. However, the collision between the electric vehicle and the protection structure will result in damage to the electric vehicle and the anti-collision structure. Furthermore, if If the impulse of an electric vehicle is too high, there is still the risk of hitting the electric vehicle charging system. It is difficult to avoid the cost of repairing the electric vehicle or the maintenance cost of the electric vehicle charging system after a collision. In addition, the movable vehicle platform of the mechanical parking system has no power supply when it is moved to a position where the vehicle can enter and exit. Therefore, the general active alarm device cannot provide an alarm function independently of the vehicle platform.

It can be seen from the above that if an electric vehicle charging system can be found, especially an electric vehicle charging system that can be installed on a vehicle platform with the effect of anti-collision warning, this will become a technical goal pursued by those skilled in the art.

In one embodiment, the power transmission interface transmits power in a non-contact manner between the transmitting end and the receiving end of the power transmission interface.

In another embodiment, the transmission end of the power transmission interface has a wireless charging transmission coil, the receiving end has a wireless charging receiving coil corresponding to the wireless charging transmission coil, and the field power device is charged through the wireless charging of the transmission end The transmission coil and the wireless charging receiving coil of the receiving end enable the electric power to be transmitted to the electric vehicle charging device.

In addition to storing power, power is also provided to the detection unit 30 and the warning unit 40 for use.

As shown in Fig. 3, it draws a schematic structural diagram of the second embodiment of the vehicle charging system with collision avoidance warning in this creation. In this embodiment, the power storage and power supply device 12 is directly connected to the receiving end 22 of the power transmission interface 20, that is, the power transmission interface 20 can respectively transmit power to the electric vehicle charging device 11 and the power storage and supply device 12, that is, The power storage and supply device 12 can obtain power directly through the power transmission interface 20 instead of the electric vehicle charging device 11. Thereby, the power storage and supply device 12 can perform power storage and supply power to the detection unit 30 and the warning unit 40.

The transmission terminal 21 and the receiving terminal 22 of the power transmission interface 20 of this creation can perform power transmission in a contact manner, that is, the power transmission interface 20 enables the transmission terminal 21 and the receiving terminal 22 to have corresponding terminals or metal terminals, such as printing plates And the design of the brush block, one end can be a copper sheet, and the other end can be an elastic bump, After the two contact, the elastic bumps can be properly contracted to achieve the effect of contact between the two, from the separated state to the corresponding contact with each other, to produce the effect of direct electrical connection, so as to transmit power from the field power equipment 50 through the power transmission interface 20 To the power supply unit 10.

In other words, when the electric vehicle is about to stop, call the vehicle carrier 60 to move to a position where the vehicle can enter. At this time, the receiving end 22 of the power transmission interface 20 is located at the vehicle carrier 60, and the vehicle carrier 60 follows the fixed position. The transmission terminal 22 is separated from each other, so the terminals or metal terminals of the transmission terminal 21 and the receiving terminal 22 are not in contact at present, or the wireless charging transmission coil of the transmission terminal 21 and the wireless charging reception of the receiving terminal 22 The two coils are inactive. After the vehicle is parked and the electric vehicle charging device 11 is connected, the vehicle carrier 60 is reset to the parking position of the vehicle carrier 60 and positioned (the aforementioned fixed-point position), and then the transmitting terminal 21 and the receiving terminal 22 move to each other To the position where the power can be coupled, that is, the terminals or metal ends of the transmitting end 21 and the receiving end 22 are close to each other and correspondingly contact, or the wireless charging transmission coil of the transmitting end 21 and the wireless charging receiving coil of the receiving end 22 are close to be sensible In this position, the electric vehicle charging device 11 can charge the electric vehicle.

Specifically, the warning unit 40 can be installed on or near the power supply unit 10, or in other conspicuous locations (for example, on the side of the vehicle carrier) to avoid warnings. The unit 40 is shielded to reduce the sound or light warning effect. According to this, when the warning unit 40 receives the warning signal sent by the detection unit 30, it will generate a corresponding warning message in real time for effective warning notification .

In one embodiment, the warning unit 40 can be a buzzer that can emit a warning sound or a light warning device that emits a warning light or light signal, or a combination of a buzzer and a light warning device can be used to simultaneously emit a sound and Light, and then achieve better warning effect. In addition, the warning unit 40 can also cooperate with the distance of the object recognized by the radar, optical radar or image recognition equipment of the detection unit 30 to generate different levels of warning effects. For example, when the object gets closer to the power supply unit 10, it emits a rapid The sound or the flashing light can indicate that the distance between the object and the power supply unit 10 is getting smaller and smaller, and a better warning effect can be achieved.

As shown in FIGS. 5A and 5B, this is a schematic diagram of the electric vehicle before entering the vehicle carrier and the electric vehicle being biased toward the power supply unit in practical applications. As shown in the figure, when the electric vehicle 70 moves to the vehicle carrier 60, if the electric vehicle 70 straddles the side of the vehicle carrier 60 and approaches the power supply unit 10, the detection unit 30 will detect the electric vehicle. When the car 70 is approached and triggered, specifically, for example, when the electric car 70 is pressed against a pressure-sensing detector or based on optical radar sensing, it is detected when the distance between the electric car 70 and the power supply unit 10 reaches a set critical distance value. The measuring unit 30 will generate a corresponding warning signal, so that after the warning unit 40 receives the warning signal, it will sound with a buzzer or display a warning light with a light warning device, thereby prompting the driving of the electric vehicle to immediately correct the driving direction. That is, it is possible to prevent the electric vehicle 70 from colliding with the power supply unit 10.
