Description

Technical Field

[0001] The present invention relates to the technical field of automotive battery swapping stations, and particularly to a new energy vehicle battery swapping station without lifting. Background Art

[0002] As one of the efficient ways to supplement the electric energy of new energy vehicles, the battery swapping mode can effectively solve the pain points of new energy vehicles, especially commercial vehicles, such as the scarcity of charging spaces, large battery capacity, and long charging time. Currently, the domestic new energy passenger vehicle battery swapping stations have been in a rapid development stage, and currently, the market passenger vehicle battery swapping stations and heavy truck battery swapping stations have been quickly put into the market and operated. However, the light truck battery swapping stations are still in the initial stage, and the battery swapping method is still in the stage of exploration, experimental verification, and the profit model is relatively not prominent.

[0003] Several key problems that usually need to be solved in the design and construction of current new energy battery swapping stations for light trucks:

[0004] Firstly, the battery swapping method is not unified. There are relevant applications for chassis battery swapping, mid-mounted battery swapping, or side-drawing battery swapping methods, but they have not been clarified and promoted.

[0005] Secondly, there is the problem of the customer's battery swapping experience. The battery thickness of light trucks for battery swapping is relatively higher than that of passenger vehicles, and the vehicle wheelbase is larger. It is necessary to lift and level the vehicle before performing the battery swapping operation. Its lifting height is relatively higher than that of passenger vehicles, resulting in a very poor battery swapping experience for the driver, and there are also certain safety hazards when lifting light truck vehicles.

[0006] Thirdly, there is the battery swapping efficiency. The batteries of light trucks are generally heavier, within 600 kg - 1000 kg. Moreover, due to the long-term driving of light truck vehicles and the change of vehicle tire pressure, it is easy to cause the vehicle and the battery to be in an inclined state at different angles, resulting in great difficulty in aligning when the existing battery swapping mechanism extracts and replaces the battery, and the running speed of the battery swapping mechanism is relatively slow, resulting in the battery swapping efficiency being much lower than that of passenger vehicles. Summary of the Invention

[0007] The present invention aims to provide a new energy vehicle battery swapping station without lifting to overcome or at least partially solve the above problems.

[0008] To achieve the above object, the technical solution of the present invention is specifically realized as follows:

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0036] See Figures 1 - 13 , a non-lifting new energy vehicle battery swapping station provided by an embodiment of the present invention includes a vehicle passing platform 1 and a container system 6. The vehicle passing platform 1 is installed in the container system 6. A battery swapping mechanism 2 and a vehicle positioning device 4 are installed on the vehicle passing platform 1, and the vehicle positioning device 4 is located on one side of the battery swapping mechanism 2. The battery swapping mechanism 2 moves along the vehicle passing platform 1. A battery storage system 3, a power supply and distribution system 7, and a fire protection system 8 are arranged outside the vehicle passing platform 1, and the battery storage system 3, the power supply and distribution system 7, and the fire protection system 8 are arranged side by side with the vehicle positioning device 4.

[0037] The battery storage system 3 is composed of one or more sets of battery racks and charging plug-in components, and the battery racks can be of multi-layer structure or single-layer structure.

[0038] The power supply and distribution system 7 realizes the power supply for all Party B's equipment in the station. Among them, video monitoring, fire protection equipment, and human-machine interaction need to be configured with UPS uninterruptible power supply, with a backup of 1 hour.

[0039] The fire protection system 8 includes fire sensors, aerosol fire extinguishers, handheld fire extinguishers, fire emergency lighting, fire controllers, fire alarms, fire transmission lines and fire water tanks. Once the fire protection system 8 detects an abnormality inside the battery, the signal can be input to the battery exchange equipment and the fire extinguishing data central controller. The battery exchange equipment can automatically transport the abnormal battery to the fire water tank outside the battery compartment through the fire transmission line. The sound and light alarms inside and outside the station are activated in time. If electrolyte leakage and open flames occur, the fire detector can detect it in time and link all fire protection equipment in the charging battery compartment.

[0040] The video monitoring system 16 can realize the interactive transmission of signal information with the host in the station, and transmit and store video information, detect moving objects, detect human behavior, recognize vehicle license plates, etc.

[0041] The PLC control system 15 is composed of a distribution cabinet, a control cabinet, a PLC, a servo motor, a servo driver, a frequency converter, a sensor, a human-machine interface and its low-voltage accessories, and realizes the PLC control of the automated operation function, data display function, interlocking and protection function of each battery exchange module equipment and the communication function with the station control system.

[0042] During use of the present invention, the vehicle enters the vehicle passage platform 1 through the entry and exit ramps, and the front wheels fall into the front wheel positioning V-grooves of the vehicle positioning device 4. The driver determines the battery replacement through the human-computer interaction system, and the push plates on both sides of the V-grooves center the vehicle. There is a visual component under the vehicle. By taking pictures of the bottom beam of the vehicle, the position of the vehicle beam in space on the X-axis, Y-axis, and Z-axis can be determined. Since the battery is placed horizontally on the vehicle beam, the X-axis, Y-axis, Z-axis and offset angle spatial positions of the battery are confirmed by confirming the beam position. The visual system feeds back the position information to the visual host 53, and then the visual system feeds back the position information to the PLC control system 15 through the station control host 17. The PLC control system 15 controls the battery replacement mechanism 2 to move through the ceiling rail 21 and the ground rail 22 inside the container, and moves to the accurate position calculated behind the vehicle. At the same time, the traction mechanism visual component 52 on the battery exchange mechanism 2 takes a picture of the battery lock position, and the visual system again processes the corresponding position information of the lock through the station control host 17 to the PLC control system 15. The PLC control system 15 commands the height adjustment screw motor 294 to operate according to the adjustment value transmitted by the station control, and then the height adjustment screw motor 294 works and drives the slider 292 to move up and down along the slide rail 293 under the side effect of the ball nut, and then drives the floating chain 291 up and down, so that the four corners of the traction trolley in the traction mechanism 27 are adjusted, so that the surface of the traction trolley and the bottom of the battery are in the same horizontal plane and parallel to each other, and the height of the floating chain 291 is automatically adjusted, and the position of the spatial X-axis, Y-axis, Z-axis and offset angle is adjusted to correspond to the rear lock of the vehicle, and the locking and unlocking are completed.

[0043] The battery swapping mechanism 2 extracts the battery from the rear of the vehicle and places the battery on the first battery swapping position 23 of the battery swapping mechanism 2. The second battery swapping position 24 on the battery swapping mechanism 2 memorizes the original X-axis, Y-axis, Z-axis and angular positions of the vehicle according to the PLC control system 15, and automatically adjusts to the original extraction position through the traction mechanism 27. The traction mechanism 27 pushes the fully charged battery rack inside to the vehicle frame and locks it.

[0044] After the locking is completed, it moves to the battery storage system 3 through the ground rail 22 and the overhead rail 21 inside the container system 6. The first battery swapping position 23 places the discharged battery in the vacant charging layer therein, then lifts to the fully charged charging layer to extract the battery, and waits in place. The first battery swapping position 23 and the second battery swapping position 24 are controlled separately, and exchange the fully charged and discharged batteries with each other, improving the battery swapping efficiency and reducing the back-and-forth running time of the equipment.

[0045] After the vehicle battery swapping is completed, the vehicle positioning device 4 returns to the origin, and the driver drives away from the vehicle passing platform 1, and the battery swapping is completed.

[0046] As Figure 2 shown, the container system 6 includes the first container 61, the second container 62 and the third container 63, and the first container 61, the second container 62 and the third container 63 are spliced together to form the container system 6. The second container 62 includes a bottom tray and an upper box, and the upper box is fixedly connected to the upper side of the bottom tray. The vehicle passing platform 1 is fixedly connected in the space formed by the bottom tray and the upper box, and extends out from the front and rear sides of the upper box. The first container 61 and the third container 63 are both box structures, and are integrally connected to the upper side of the bottom tray, and are placed on the left and right sides of the second container 62, and the import area of the box structure is hollowed out.

[0047] The battery storage system 3, the power supply and distribution system 7 and the fire protection system 8 are all arranged in the first container 61. Inside the container system 6, there are also a network system 14, a PLC control system 15, a video monitoring system 16 and a station control host 17. The video monitoring system 16 is arranged on the inner top of the container system 6. The station control host 17 and the PLC control system 15 are both arranged in the third container 63, and the PLC control system 15, the video monitoring system 16 and the station control host 17 are communicatively connected to each other through the network system 14. The network system 14 includes a charging switch, a battery swapping switch, a router / 5G router, a network connector, a network cable and a three-layer switch. The network system 14 is used to realize the unified planning and configuration of network IP addresses supported by the cloud platform. By arranging the container system 6 outside the battery swapping station, the purpose of protecting the battery swapping equipment from wind and rain is achieved, ensuring the operation stability of each equipment. At the same time, the container system 6 is composed of containers, achieving the purpose of easy selection and low production cost.

[0048] AsFigure 3 As shown in the figure, the vehicle access platform 1 includes an entrance ramp 11, an exit ramp 12, and a parking platform 13. The entrance ramp 11 and the exit ramp 12 are symmetrically fixed to the front side and the rear side of the parking platform 13 respectively. There are notches for fixedly placing the vehicle positioning device 4 and notches for installing the lift table 9 on the parking platform 13. The parking platform 13 is welded by a steel structure frame. The included angle between the ramp surfaces of the entrance ramp 11 and the exit ramp 12 and the horizontal plane is 6°. Anti-slip strips are welded and fixed on the ramp surfaces, which facilitates the vehicle to enter the battery swapping station from the entrance ramp 11 and exit from the exit ramp 12. Controlling the ramp surface at 6° ensures the stability and safety of the vehicle going uphill and downhill, and the anti-slip strips improve the stability of the vehicle going uphill and downhill.

[0049] As Figure 1 , Figure 9 and Figure 10 As shown in the figure, the vehicle positioning device 4 includes a front-wheel centering mechanism 41 and a rear-wheel centering mechanism 42. Both the front-wheel centering mechanism 41 and the rear-wheel centering mechanism 42 are fixed on the parking platform 13. The front-wheel centering mechanism 41 is provided with a V-groove structure, which is convenient for the vehicle to stop in place and realizes the centering positioning of the vehicle's front wheels. The rear-wheel centering mechanism 42 is provided with a clamping mechanism, which is convenient for adjusting and clamping the vehicle's wheels and realizes the centering positioning of the vehicle's rear wheels. The power of the clamping mechanism adopts any one of hydraulic and motor drive.

[0050] As Figure 1 and Figure 5 As shown in the figure, the lift table 9 is located above the parking platform 13, and a vehicle distance detection sensor 91 is fixedly connected to the lift table 9. The distance between the vehicle's wheels and the lift table 9 is detected by the vehicle distance detection sensor 91, and the rear-wheel centering mechanism 42 is controlled to adjust the wheel position to ensure the parallelism between the vehicle's tail and the battery swapping mechanism 2. After the battery swapping vehicle moves onto the parking platform 13 and is centered and positioned by the front-wheel centering mechanism 41 and the rear-wheel centering mechanism 42, the lift table 9 moves upward and moves above the parking platform 13, thereby driving the vehicle distance detection sensor 91 to move upward. Then, the vehicle distance detection sensor 91 measures the distances between the two front wheels and the two rear wheels from the vehicle distance detection sensor 91, and then transmits the measurement information to the station control host 17 and sends it down to the PLC control system 15 to control the drivers and motors on the front-wheel centering mechanism 41 and the rear-wheel centering mechanism 42 to operate, so as to perform secondary adjustment on the front wheels and rear wheels of the battery swapping vehicle, thereby ensuring that the tail of the battery swapping vehicle and the front part of the battery swapping mechanism 2 are in a parallel state.

[0051] As Figure 8 and Figure 12As shown in the figure, it further includes a vision mechanism 5. The vision mechanism 5 includes a vehicle bottom vision component 51, a traction mechanism vision component 52, and a vision host 53. Both the vehicle bottom vision component 51 and the traction mechanism vision component 52 are connected to the vision host 53 through wires. The vehicle bottom vision component 51 is fixed on the parking platform 13, and multiple sets of vehicle bottom vision components 51 are provided. The vehicle bottom vision component 51 measures the position of the vehicle's girder and judges the position of the battery relative to the ground by taking pictures. The traction mechanism vision component 52 is installed on the battery swapping mechanism 2. By taking pictures of the position of the vehicle end lock hole, it transmits the position offset data information to the vision host 53, and issues commands to the PLC to direct the battery swapping mechanism 2 to achieve automatic adjustment in the X-axis direction, Y-axis direction, Z-axis direction, and offset angle.

[0052] As Figure 8 As shown in the figure, the vehicle bottom vision component 51 includes a motor 511 and an intelligent camera 513. The motor 511 is fixed on the fixed seat 131, and the fixed seat 131 is fixedly installed inside the parking platform 13. The output end of the motor 511 is connected to one end of the lead screw 514, and the other end of the lead screw 514 is rotatably connected to the support seat through a bearing. The lead screw 514 is connected to the shielding block 512 through a ball screw pair. The shielding block 512 is arranged on the upper side of the fixed seat 131 and is slidably connected to the fixed seat 131 through a guide rail. The intelligent camera 513 is fixedly connected to the inner side of the shielding block 512. When the motor 511 operates, it drives the lead screw 514 to rotate. The lead screw 514 rotates and drives the folding block to move along the guide rail under the action of the ball screw pair, thereby driving the intelligent camera 513 to move. This realizes moving the intelligent camera 513 from inside the parking platform 13 to the opening on the parking platform 13. Through the opening on the parking platform 13, the intelligent camera 513 can conveniently measure the position of the vehicle bottom girder and the battery. When the intelligent camera 513 is inside the parking platform 13, the parking platform 13 can protect the intelligent camera 513 to prevent the battery swapping vehicle from pressing on the intelligent camera 513.

[0053] As Figure 6As shown, the battery swapping mechanism 2 includes a first battery swapping station 23 and a second battery swapping station 24. The first battery swapping station 23 and the second battery swapping station 24 are provided with equipment frames 25, lifting components 26, traction mechanisms 27, and locking and unlocking devices 28 inside. The lifting components 26, traction mechanisms 27, and locking and unlocking devices 28 are all installed within the equipment frames 25. The lifting components 26 are fixed to the tops of the equipment frames 25 and drive the traction mechanisms 27 to move up and down through sprockets and chains. A locking and unlocking device 28 for locking and unlocking and disassembling and assembling the battery is installed on the traction mechanism 27, and a traction mechanism vision component 52 is installed on the locking and unlocking device 28. An overhead rail 21 and a ground rail 22 are respectively arranged on the upper and lower sides of the first battery swapping station 23 and the second battery swapping station 24. The overhead rail 21 is fixedly connected to the inner top of the container system 6, and the ground rail 22 is fixedly connected within the parking disc platform. The first battery swapping station 23 and the second battery swapping station 24 are respectively slidably connected to the overhead rail 21 and the ground rail 22 through the walking wheel assemblies 10. The overhead rail 21 and the ground rail 22 facilitate the left and right movement of the first battery swapping station 23 and the second battery swapping station 24 on the battery swapping mechanism 2, thereby conveniently driving the traction mechanism 27 to move synchronously, facilitating the control of the position of the forward movement mechanism, and also facilitating the left and right movement of the battery swapping mechanism 2 to control the movement of the battery swapping vehicle. After the battery swapping is completed, the battery swapping mechanism 2 moves to the rear of the battery storage system 3. At this time, the road of the exit ramp 12 is opened, facilitating the battery swapping vehicle to drive out of the battery swapping station.

[0054] As Figure 7 and Figure 11As shown in the figure, the traction mechanism 27 includes a frame body and a traction trolley. The traction trolley is arranged inside the frame body, and a height adjustment mechanism 29 is connected between the frame body and the traction trolley. There are four height adjustment mechanisms 29, and all four height adjustment mechanisms 29 are connected to the PLC control system 15 through wires. The height adjustment mechanism 29 includes a floating chain 291 and a height adjustment lead screw motor 294. The height adjustment lead screw motor 294 is fixedly connected to the top of the frame. The lower side of the height adjustment lead screw motor 294 is connected to a slider 292 through a ball screw pair. One end of the floating chain 291 is connected to the lower end of the slider 292, and the other end of the floating chain 291 is connected to the traction trolley. The slider 292 is arranged on one side of the slide rail 293 and is slidably connected to the slide rail 293. The slide rail 293 is fixedly connected to the outside of the frame. The floating chains 291 are arranged at the four corners of the traction trolley. The positions of the vehicle bottom girder and the battery, as well as the position of the battery lock hole, are measured by the vehicle bottom vision component 51 and the traction mechanism vision component 52. Then, the PLC control system 15 is used to control the operation of the height adjustment lead screw 514, and drive the four floating chains 291 at the surrounding positions of the traction trolley to move up or down, so as to control the height and offset angle of the traction trolley, ensuring that the upper surface of the traction trolley is on the same horizontal plane as the bottom surface of the battery to be replaced and parallel to each other, which is convenient for quickly extracting the battery. When a fully charged battery needs to be installed in the battery swapping vehicle, first tow the fully charged battery to the traction trolley, and then the PLC control system 15 adjusts the height and offset angle of the traction trolley, so that the traction trolleys at the battery swapping station 1 23 and the battery swapping station 2 24 are at the same height and parallel to each other. Then, the fully charged battery can be quickly installed on the battery swapping vehicle.

[0055] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
