Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping station technology, and in particular to a vehicle auxiliary positioning system for use in chassis-type commercial vehicle battery swapping stations. Background Technology

[0002] Automatic battery swapping for new energy vehicles is one of the most efficient ways to replenish their power, far exceeding the efficiency of current mainstream charging piles. Currently, battery swapping for new energy vehicles in China is still in its early, rapid development stage. With the rapid growth in vehicle sales, a shortage of charging supply has emerged. Since 2020, the government has introduced a series of supportive policies, which will lead to rapid development in the field of automated battery swapping for new energy vehicles. While heavy-duty truck-mounted battery swapping technology is quite mature, this method requires placing the battery box directly above the vehicle. This layout has the following drawbacks: 1. The space above the vehicle is already limited; placing the battery box there further compresses the space. 2. Mounted commercial vehicles increase the vehicle's center of gravity, worsening its balance. Therefore, chassis-mounted battery swapping commercial vehicles are being applied and promoted.

[0003] In the construction of new energy vehicle battery swapping stations, the applicable range of RGVs for battery swapping in chassis-type commercial vehicle battery swapping stations is limited. Therefore, the parking position of the vehicle directly affects the success or failure of our automatic battery swapping. Furthermore, different vehicle models and wheelbases require drivers to park the vehicle within the effective range. It is difficult for drivers to park the vehicle in the correct position by feeling alone. Therefore, research on a vehicle auxiliary positioning system that can visually identify the vehicle model and automatically adjust the vehicle's stopping position is particularly important.

[0004] The current vehicle auxiliary positioning system for chassis-type battery swapping stations has the following problems that need to be addressed:

[0005] 1. Different vehicle wheelbases result in different stopping positions, making drivers unsure if their stopping position is within acceptable limits, causing anxiety and a poor battery swapping experience.

[0006] 2. After the battery swap is completed, the existing mechanisms on the market require the front barrier to be moved before the vehicle can be started, which affects the overall battery swap efficiency.

[0007] 3. The existing vehicle braking mechanism is poorly designed, causing the vehicle to slip when reversing.

[0008] 4. The impact force on the positioning mechanism is very large when the vehicle stops and starts, which can easily cause damage to the walking mechanism. Summary of the Invention

[0009] The present invention aims to provide a vehicle auxiliary positioning system for use in chassis-type commercial vehicle battery swapping stations to overcome or at least partially solve the above-mentioned problems.

[0010] To achieve the above objectives, the technical solution of the present invention is specifically implemented as follows:

[0017] As a further embodiment of the present invention, the V-groove lifting assembly II includes a traveling fixed plate. A motor drive assembly is fixedly connected to the upper side of the traveling fixed plate and engages with a rack through the motor drive assembly, thereby driving the traveling fixed plate to move along the rack. A positioning support plate is provided on the upper side of the traveling fixed plate, and a positioning groove matching the positioning block is opened on the positioning support plate. An electric push rod is fixedly connected to the lower side of the traveling fixed plate, and the telescopic rod on the electric push rod is fixedly connected to the bottom surface of the positioning support plate.

[0018] As a further embodiment of the present invention, a slider is fixedly connected to one side of the lower side of the walking fixing plate, and the slider is sleeved on the linear guide rail and moves along the linear guide rail.

[0019] As a further embodiment of the present invention, linear guide rails are fixedly connected to the front and rear sides of the positioning plate, and linear guide rails are slidably connected to sliders.

[0021] This invention provides a vehicle auxiliary positioning system for use in battery swapping stations for chassis-type commercial vehicles, with the following advantages:

[0022] The V-groove lifting component moves synchronously to drive the V-groove speed bump, thereby adjusting the position of the V-groove speed bump. This facilitates positioning for different vehicle models and enables the battery swapping station to meet the battery swapping needs of different vehicles and vehicles with different wheelbases.

[0023] By controlling the slope of the speed bump support, the vehicle can easily drive into and out of the speed bump while having a clear sense of positioning, which can greatly improve the battery swapping experience.

[0024] By combining the V-groove speed bump with the V-groove lifting assembly, the components can be connected during lifting and separated during positioning. This ensures that the impact force generated when the vehicle stops and starts during positioning is directed only at the V-groove speed bump and not transmitted to the V-groove lifting assembly. This guarantees the accurate positioning of the V-groove speed bump and the vehicle by the V-groove lifting assembly during operation, resulting in high positioning accuracy, safety, and stability.

[0025] The chassis-type commercial vehicle battery swapping station is suitable for different vehicle models. The station control system controls the V-slot to stop at the required position. When the front wheels of the vehicle drive to the center of the V-slot, the vehicle is in the battery swapping position. This provides a good solution for the battery swapping station to meet the needs of different vehicles and vehicles with different wheelbases to achieve automatic battery swapping.

[0036] See Figure 1 This invention provides a vehicle auxiliary positioning system for a battery swapping station for chassis-type commercial vehicles, comprising a V-groove speed bump assembly 1, a crash barrier 5, and a photoelectric sensor assembly 7. A V-groove lifting assembly 1 (first) and a V-groove lifting assembly 2 (second) are disposed on the left and right sides of the V-groove speed bump assembly 1, with the second V-groove lifting assembly 2 (second) positioned on one side of the first V-groove lifting assembly 2 and movable along the first V-groove lifting assembly 2. A V-groove positioning assembly 4 and a cable chain assembly 3 are respectively disposed on the left and right sides of the first V-groove lifting assembly 2, with the cable chain assembly 3 positioned outside the positioning assembly 4 and the positioning assembly 4 positioned below the second V-groove lifting assembly 2 (second). The photoelectric sensor assembly 7 is disposed between the first V-groove lifting assembly 2 and the cable chain assembly 3 and is fixedly connected to the first V-groove lifting assembly 2. The crash barrier 5 is disposed on the left and right sides of the V-groove speed bump assembly 1.

[0037] like Figure 2As shown, the V-groove speed bump assembly 1 includes a speed bump base 11. Side wall lifting plates 17 are fixedly connected to both the left and right sides of the speed bump base 11, and a support plate 13 is fixedly connected to the top of the side wall lifting plate 17. A positioning block 12 is fixedly connected to the lower side of the support plate 13, and a positioning pin 15 is fixedly connected to the lower side of the side wall lifting plate 17. The speed bump base 11 has a height of 70mm and a V-groove slope of 16-17°.

[0038] The side wall lifting plate 17 and the support plate 13 form an L-shape, and a reinforcing plate 14 is fixedly connected at the angle between the side wall lifting plate 17 and the support plate 13. A fixing block 16 is fixedly connected to the lower side of the side wall lifting plate 17, and a positioning pin 15 is fixedly connected to the lower side of the fixing block 16. The positioning pin 15 extends into the positioning hole, which facilitates the positioning of the speed bump support 11 by the positioning guide rail 43. Lifting the support plate 13 facilitates the simultaneous lifting of the speed bump support 11, which in turn facilitates the movement of the speed bump support 11 and the adjustment of its position.

[0039] like Figure 3 As shown, the V-groove lifting assembly 2 includes a linear guide rail 21. A travel shaft guide rail 22 is fixedly connected to the lower side of the linear guide rail 21. Multiple base plates 24 are fixedly connected to the bottom surface of the travel shaft guide rail 22. A rack pad 23 is fixedly connected to the upper side of the travel shaft guide rail 22, and a rack 26 is fixedly connected to the upper side of the rack pad 23. The rack 26 is located on one side of the linear guide rail 21. Positioning members 25 are fixedly connected to both the front and rear sides of the travel shaft guide rail 22. The positioning members 25 are located on the front and rear sides of the linear guide rail 21. The rack 26 is fixed by the base plates 24, and the rack 26 facilitates the guidance of the movement of the travel fixing plate 62.

[0040] like Figure 4 As shown, the cable chain assembly 3 includes a cable chain tray 34, on the upper side of which a cable chain 33 is disposed. One side of the cable chain 33 is fixedly connected to the cable chain tray 34, and the other side is fixedly connected to the cable chain connecting plate 32. Multiple switch brackets 31 are fixedly connected to the side of the cable chain tray 34 near the cable chain connecting plate 32. The cable chain connecting plate 32 is fixedly connected to the travel fixing plate 62 by bolts. The movement of the travel fixing plate 62 facilitates the movement of the cable chain 33, while the cable chain 33 facilitates the storage, placement and organization of the wires that are respectively connected to the motor drive assembly 63 and the electric push rod 65.

[0041] like Figure 5As shown, the V-groove positioning assembly 4 includes a first positioning guide rail 42 and a second positioning guide rail 43. The second positioning guide rail 43 is fixed on the upper side of the first positioning guide rail 42, and a plurality of positioning holes for positioning with the positioning pin 15 are equally spaced on the second positioning guide rail 43. An adjustment block 44 and a base plate 41 are provided on the lower side of the first positioning guide rail 42, and the adjustment block 44 is located between the first positioning guide rail 42 and the base plate 41. The positioning holes on the second positioning guide rail 43 are matched and engaged with the positioning pin 15, which facilitates the positioning of the side lifting plate through the second positioning guide rail 43, and thus the positioning of the speed bump base 11.

[0042] like Figure 6 As shown, the V-groove lifting assembly 6 includes a traveling fixed plate 62. A motor drive assembly 63 is fixedly connected to the upper side of the traveling fixed plate 62 and meshes with the rack 26 through the motor drive assembly 63, thereby driving the traveling fixed plate 62 to move along the rack 26. A positioning support plate 64 is provided on the upper side of the traveling fixed plate 62, and a positioning groove 66 matching the positioning block 12 is opened on the positioning support plate 64. An electric push rod 65 is fixedly connected to the lower side of the traveling fixed plate 62. The telescopic rod on the electric push rod 65 is fixedly connected to the bottom surface of the positioning support plate 64. The motor drive assembly 63 includes a servo motor, a reducer, and gears. The gears are located on the traveling fixed plate 62. The lower side of the plate 62 is connected to the rack 26 through gear meshing. The servo motor and reducer are fixed on the upper side of the traveling fixed plate 62. The servo motor, reducer and gear are connected together. The operation of the servo motor and reducer drives the gear to rotate, thereby moving the gear along the rack 26, thereby driving the traveling fixed plate 62 to move along the rack 26. The operation of the electric push rod 65 drives the positioning plate 64 to move upward. Then the positioning groove 66 on the positioning plate 64 matches and fits on the positioning block 12. Then the extension and retraction of the electric push rod 65 drives the support plate 13 to move up and down, thereby lifting and lowering the speed bump base support 11.

[0043] A slider 61 is fixedly connected to one side of the lower side of the walking fixed plate 62, and the slider 61 is sleeved on the linear guide rail 21 and moves along the linear guide rail 21. By moving the slider 61 along the linear guide rail 21, the movement of the walking fixed plate 62 is guided.

[0044] Linear guide rails 69 are fixedly connected to the front and rear sides of the positioning plate 64, and linear guide rails 69 are slidably connected to sliders 68. Slider 68 is fixed to the lower side of the traveling plate 62 by slider fixing plate 67. A baffle 610 is fixedly connected to the bottom surface of linear guide rails 69. Linear guide rails 69 move up and down along sliders 68 to guide the movement of positioning plate 64, and baffle 610 limits the movement of linear guide rails 69.

[0045] like Figure 6 and Figure 7 As shown, the photoelectric sensing component 7 includes an aluminum profile 71, a photoelectric switch 73, and a photoelectric switch sensing element 74. A profile bracket 72 is fixedly connected to the lower side of the aluminum profile 71, and the profile bracket 72 is bolted to one side of the travel shaft guide rail 22. Multiple switch brackets 31 are fixedly connected to the aluminum profile 71, and a photoelectric switch 73 is fixedly connected to each switch bracket 31. The photoelectric switch 73 is also fixed to the positioning plate 64. The photoelectric switch sensing element 74 is fixed to both the travel mounting plate 62 and the support plate 13, and the photoelectric switch sensing element 74 and the photoelectric switch 73 are connected one-to-one. Correspondingly, by fixing the aluminum profile 71 to one side of the travel shaft guide rail 22, when the V-groove lifting component 26 moves along the rack 26, the photoelectric switch sensing plate 74 and photoelectric switch 73 on it are moved simultaneously. When the photoelectric switch sensing plate 74 on the travel fixing plate 62 corresponds and identifies with the photoelectric switch 73 on the aluminum profile 71, and when the photoelectric switch 73 on the travel fixing plate 62 corresponds and identifies with the photoelectric switch sensing plate 74 on the support plate 13, the moving position of the V-groove lifting component 26 can be accurately positioned and controlled.

[0046] During the use of this invention:

[0047] First, a vision system camera is installed at the gate position, and a control system is set up in the station control cabinet. The software algorithm is input into the vision system and the control system. At the same time, the electrical control system is arranged in the station control electrical cabinet. Then, the V-groove speed bump assembly 1, V-groove lifting assembly 1 2, drag chain assembly 3, V-groove positioning assembly 4, anti-collision barrier 5, V-groove lifting assembly 2 6, and photoelectric sensor assembly 7 are all located on the battery swapping platform.

[0048] Before a vehicle enters the battery swapping platform, a vision system camera at the gate takes a picture of the vehicle. The vision system matches the vehicle information, and then a software algorithm determines the battery swapping location where the vehicle needs to stop. The station control sends the obtained information to the electronic control system. The electronic control system controls the V-groove lifting component 2 6 to rise and lift the V-groove speed bump component 1. Then, it controls the motor drive component 63 to move to the designated position, thereby moving the speed bump base 11 to the designated position. Then, it controls the V-groove lifting component 2 6 to descend, so that the positioning pin 15 in the V-groove speed bump component 1 falls into the positioning hole in the V-groove positioning component 4. At this time, the speed bump base 11 in the V-groove speed bump component 1 is accurately positioned by the V-groove positioning component and falls on the battery swapping platform. At this time, the front tires 8 of the vehicle begin to drive into the speed bump base 11. The vehicle positioning is completed, and the driver starts the battery swapping through the human-machine interaction system. After the battery swapping, the vehicle can drive directly out of the speed bump base 11 without waiting.

[0049] To overcome the problems 1, 2, and 3 mentioned above, the following design calculations were performed.

[0050] Taking a certain heavy truck as an example (with a wheel-to-ground friction coefficient of 0.4), when the truck drives out of the V-groove without slipping:

[0051] The vehicle's maximum traction force = u * mg / 2 = 0.4 * 13000 * 9.8 / 2 = 2.55 * 10^4 N.

[0052] The upward component of the force along the slope = 2.55 * 10^4 N * cos18° = 25252 N.

[0053] At this moment, the car needs to overcome the resistance to upward motion = mg / 2 * sin12° + u * mg / 2 = 6500 * 9.8 * sin18° + 6500 * 9.8 * 0.09 = 25480 N.

[0054] At this point, the traction force is approximately equal to the resistance force, so it is necessary to increase the friction on the ground or make the car move. Only with inertial force can it drive out of the V-groove. The angle of the V-groove for this model cannot exceed 18° during the design process. Therefore, our speed bump support 11 is designed with a height of 70mm and an incline of 16-17°. Through on-site testing, this height and angle allow the driver to easily drive the vehicle into and out of the speed bump while also having a clear sense of positioning, which can greatly improve the battery swapping experience.

[0055] To overcome the slippage problem, patterned strips are welded to the upper surface of the speed bump support 11. Since the speed bump is designed as a ramp for both entering and exiting, it can be driven out directly after the battery swap is completed.

[0056] To overcome problem 4 mentioned above, the following design was implemented.

[0057] Positioning is performed in the Y direction by positioning the fixed block 16 and the positioning slot 66, and then in the X direction by positioning the positioning pin 15 and the positioning hole in the positioning guide rail 43. After positioning is completed, the V-groove lifting component 26 descends. At this time, the V-groove lifting component 26 and the V-groove deceleration belt component 1 are separated. The vibration caused by the impact force of the vehicle entering the V-groove deceleration belt component 1 will not be transmitted to the V-groove lifting component 26, thus protecting the servo motor in the V-groove lifting component 26 and the linear guide rail and rack 26 of the V-groove lifting component 12, and ensuring the repeatability of the V-groove lifting component.

[0058] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
