Description

Technical Field

[0001] The invention relates to a wheel positioning device, a battery swap station and a control method for a battery swap station. Background Art

[0002] The vehicle loading platform is an important part of the battery replacement equipment for electric vehicles. When the electric vehicle drives onto the vehicle loading platform, the vehicle positioning device can locate the electric vehicle.

[0003] At present, the vehicle positioning device generally uses a V-shaped groove to position the wheel. When the wheel enters the V-shaped groove, the vehicle is parked and the battery replacement begins. The advantage of this positioning method is that the vehicle positioning device is simple and reliable, and does not require a too complicated mechanism to achieve the positioning of the electric vehicle in the front and rear directions. However, due to structural limitations, the existing vehicle positioning device is generally a fixed V-shaped positioning component, and the positioning component protrudes or sinks into the vehicle platform. When the electric vehicle enters the V-shaped positioning component, the driver has a clear feeling of driving into a pit at the moment the wheel enters the groove. After the battery replacement is completed, when the V-shaped positioning component is driven out, the electric vehicle needs to increase the throttle to drive out of the groove. The electric vehicle will feel bumpy when passing the V-shaped positioning component, and the driver experience is relatively poor.

[0004] In the patent document with the patent authorization announcement number CN211765460U, an improvement is made to the vehicle positioning device in which the positioning component protrudes from the vehicle loading platform, by setting a push rod or a servo motor to drive the two blocking components to expand or close in different directions, thereby forming a wheel limit space or preventing the vehicle from being bumped. However, the patent is based on a positioning component in an upward convex manner. If the blocking component fails, it will always lie flat and cannot give the driver a signal that the vehicle has stopped. Summary of the invention

[0082] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0083] Example 1

[0084] like Figure 1 , Figure 2 and Figure 3 As shown, the battery swap station of the embodiment of the present invention includes a wheel alignment device for the battery swap station and a battery swap station body 10, the wheel alignment device is arranged on the battery swap station body 10, and the wheel alignment device is installed at the position where the wheel of the corresponding vehicle is parked.

[0085] The wheel positioning device for a battery swap station includes a limiting device 1, a cover plate 2 and a driving assembly. The limiting device 1 is used to be installed on a battery swap station body 10. The limiting device 1 includes two positioning inclined surfaces 11. The two positioning inclined surfaces 11 are both inclined downward from the upper surface of the battery swap station body 10 and form an inwardly concave angle, and the two positioning inclined surfaces 11 are respectively used to limit the two movement trends of the vehicle's wheels forward and backward; the cover plate 2 is used to block or expose the opening 12 formed between the two positioning inclined surfaces 11; the driving assembly is used to drive the cover plate 2 to move.

[0086] The limiting device 1 is installed at the position where the wheel of the corresponding vehicle is parked. Before the wheel of the vehicle enters the wheel alignment device for positioning, the cover plate 2 is exposed at the opening 12 formed between the two positioning inclined surfaces 11, so that the wheel of the vehicle will be located between the two positioning inclined surfaces 11 when entering the wheel alignment device. The two positioning inclined surfaces 11 are used to limit the two movement trends of the wheel of the vehicle forward and backward respectively, so that the wheel of the vehicle is limited between the two positioning inclined surfaces 11, thereby achieving precise positioning and avoiding vehicle displacement during battery replacement operation.

[0087] Before the wheels of the vehicle need to pass through the wheel alignment device, the driving assembly is used to drive the cover plate 2 to move, so that the cover plate 2 is blocked at the opening 12 formed between the two positioning slopes 11. The wheels of the vehicle will walk on the cover plate 2 without falling into the opening 12, thereby reducing the bumpy feeling when the wheels pass through the wheel alignment device, greatly improving the experience. Even if the driving assembly fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression will always exist and cannot be flattened, so at least the positioning function can be achieved; at the same time, the driving assembly is used to drive the cover plate 2 to move, which has the advantages of simple control and high stability, and the moving force is more stable, which prolongs the service life.

[0088] In this embodiment, when the cover plate 2 is at the position of blocking the opening 12, the bottom surface of the cover plate 2 is flush with the upper surface of the radio body 10. The driving assembly drives the cover plate 2 to move, so that when the cover plate 2 is at the position of blocking the opening 12, the bottom surface of the cover plate 2 is flush with the upper surface of the radio body 10, so that the bottom surface of the cover plate 2 can move in close contact with the upper surface of the radio body 10, which has the advantages of simple control and high stability, realizes more stable movement force, and prolongs the service life.

[0089] In one embodiment, when the cover plate 2 is at the shielding opening 12, the top surface of the cover plate 2 is flush with the upper surface of the radio body 10. The cover plate 2 is driven by the driving component to move so that the top surface of the cover plate 2 is flush with the upper surface of the radio body 10, so that the vehicle passes through the wheel alignment device without any bumps, and the experience is the best. Of course, in other embodiments, the driving component can drive the cover plate 2 to move until the top surface of the cover plate 2 is slightly lower than or slightly higher than the upper surface of the radio body 10.

[0090] In this embodiment, the cover plate 2 is located on the upper surface of the wheel change station body 10 and moves on the upper surface of the wheel change station body 10. The cover plate 2 is driven by the driving assembly to move on the upper surface of the wheel change station body 10, which effectively avoids the displacement and dislocation of the cover plate 2 during the movement, and greatly improves the stability of the wheel alignment device.

[0091] The body 10 of the wheel change station is provided with a slide groove, and the cover plate 2 is located in the slide groove and does not protrude from the upper surface of the body 10 of the wheel change station. The cover plate 2 moves along the slide groove to cover the opening 12. The slide groove can limit the sliding of the cover plate 2, effectively avoiding the displacement and dislocation of the cover plate 2 during the sliding process, greatly improving the stability of the wheel alignment device. At the same time, the space of the cover plate 2 is used to accommodate the cover plate 2, so that the cover plate 2 does not protrude from the upper surface of the body 10 of the wheel change station, thereby reducing the bumpy feeling when the vehicle passes through the wheel alignment device, greatly improving the experience.

[0092] In one embodiment, the driving assembly is installed below the radio changer body 10. A connecting groove 101 is provided on the radio changer body 10, and the movable end of the driving assembly passes through the connecting groove 101 and is connected to the bottom of the cover plate 2. The driving assembly can be installed below the radio changer body 10, and can be connected to the bottom of the cover plate 2 on the radio changer body 10 through the connecting groove 101, so as to make full use of the space and facilitate the installation of the driving assembly; at the same time, the space on the radio changer body 10 is not occupied, interference is avoided, and the passage of vehicles is ensured.

[0093] In another embodiment, the cover plate 2 is located below the radio changer body 10 and moves along the radio changer body 10 to extend between the two positioning inclined surfaces 11 and cover the opening 12. The cover plate 2 is not set on the radio changer body 10 but below the radio changer body 10, which effectively avoids interference between the cover plate 2 and the wheel, ensures that the wheel does not pass through the cover plate 2, reduces the bumpy feeling, and greatly improves the experience. At the same time, the cover plate 2 is set in the space below the radio changer body 10 to fully utilize the space.

[0094] In one embodiment, the cover plate 2 is above the radio changer body 10 and moves in a direction close to or away from the opening 12. The driving assembly drives the cover plate 2 to move above the radio changer body 10 to cover or expose the opening 12. The cover plate 2 is arranged above the radio changer body 10, so that the cover plate 2 is very convenient to install.

[0095] In another embodiment, the cover plate 2 is located below the radio changer body 10 and moves in a direction close to or away from the opening 12. The driving assembly drives the cover plate 2 to move below the radio changer body 10, effectively avoiding interference between the cover plate 2 and the wheel, ensuring that the wheel does not pass through the cover plate 2, thereby reducing the bumpy feeling and greatly improving the experience. At the same time, the cover plate 2 is set in the space below the radio changer body 10 to fully utilize the space.

[0096] In this embodiment, the cover plate 2 moves above the radio body 10 along the vehicle driving direction and is located behind the limiting device 1. The cover plate 2 can cover the opening 12 formed between the two positioning inclined surfaces 11 as the vehicle travels, and will not interfere with the wheels.

[0097] In another embodiment, the cover plate 2 can also move perpendicular to the vehicle's driving direction above the radio body 10. When the cover plate 2 is not blocking the opening 12 formed between the two positioning slopes 11, the vehicle will not pass over the cover plate 2, so as to reduce the number of times the cover plate 2 is run over by the vehicle, thereby extending the service life of the cover plate 2.

[0098] The drive assembly is installed on the outside of the station body 10, and the movable end of the drive assembly extends to the station body 10 and is connected to the cover plate 2. The drive assembly is installed on the outside of the station body 10, which will not occupy the space on the station body 10, avoid interference, and ensure the passage of vehicles. The drive assembly includes a cylinder, a hydraulic cylinder, an electric push rod or an airbag. Therefore, a suitable drive assembly can be selected according to space, cost, etc.

[0099] In this embodiment, the limiting device 1 further includes two positioning members 13, both of which are used to be installed on the radio body 10 and protrude from the upper surface of the radio body 10, and the two positioning members 13 are used to limit the two movement trends of the vehicle's wheels to the left and the wheels to the right, respectively, so that the vehicle's wheels are limited between the two positioning members 13. The two movement trends of the vehicle's wheels to the left and the wheels to the right are limited by the two positioning members 13, and the two movement trends of the vehicle's wheels forward and backward are limited by the two positioning inclined surfaces 11, thereby limiting the movement trends of the wheels to the surroundings, greatly improving the precise positioning of the vehicle by the wheel positioning device.

[0100] In this embodiment, rollers are provided on the surface of the positioning member 13 facing the wheel. When positioning the wheel, the two positioning members 13 are used to limit the two movement trends of the vehicle wheel to the left and the wheel to the right respectively. The rollers facilitate the movement and adjustment of the wheel on the two positioning members 13, making it easy to adjust the wheel to achieve precise positioning. Of course, in other embodiments, a ball bearing is provided on the surface of the positioning member 13 facing the wheel.

[0101] Example 2

[0102] like Figure 4 As shown, in this embodiment, a vehicle positioning control method is disclosed. The vehicle positioning control method is used for the above-mentioned radio station change. The vehicle positioning control method includes the following steps:

[0103] Step 101 , after the vehicle reaches the switching point of the switching station body 10 and is lifted, the cover plate 2 is driven to move and cover the opening 12 .

[0104] In this embodiment, the limiting device 1 is installed at the position where the wheels of the corresponding vehicle are parked. After the vehicle reaches the changing position of the radio station body 10 and is lifted, the cover plate 2 is driven to move by the driving component so that the cover plate 2 will block the opening 12. When the wheels of the vehicle pass through the wheel positioning device, they walk on the cover plate 2 without falling into the opening 12, thereby reducing the bumpy feeling of the wheels when passing through the wheel positioning device, greatly improving the experience. Even if the driving component fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression will always exist and cannot be flattened, so at least the positioning function can be achieved; at the same time, it has the advantages of simple control and high stability, and the moving force is more stable, which prolongs the service life.

[0105] The vehicle positioning control method may further include the following steps:

[0106] Step 102 , after the vehicle drives out of the switching point of the switching station body 10 , the cover plate 2 is driven to move and be exposed at the opening 12 .

[0107] In this step, after the vehicle drives out of the battery replacement station body 10, the cover 2 is driven to move by the driving assembly so that the cover 2 is exposed at the opening 12, so that the wheels of the vehicle will be located between the two positioning slopes 11 when entering the wheel positioning device. The two positioning slopes 11 are used to limit the two movement trends of the vehicle's wheels forward and backward respectively, so that the wheels of the vehicle are limited between the two positioning slopes 11, thereby achieving precise positioning and avoiding vehicle displacement during battery replacement operation.

[0108] Example 3

[0109] like Figure 5As shown, in this embodiment, a vehicle positioning control method is disclosed, and the vehicle positioning control method is used in the above-mentioned station change, and the wheel positioning device is installed at the position where the front wheel of the corresponding vehicle stops, that is, the limiting device 1 is installed at the position where the front wheel of the corresponding vehicle stops. The vehicle positioning control method includes the following steps:

[0110] Step 201 : After the front wheels of the vehicle leave the limiting device 1 corresponding to the front wheel parking place, the driving cover plate 2 moves to cover the opening 12 corresponding to the front wheel parking place.

[0111] In this step, after the front wheels of the vehicle leave the limiting device 1 corresponding to the front wheel parking place, the rear wheels of the vehicle have not left the limiting device 1 corresponding to the front wheel parking place, and the cover plate 2 is driven to move by the driving component, so that the cover plate 2 will block the opening 12 corresponding to the front wheel parking place, and then the rear wheels of the vehicle will walk on the cover plate 2 when passing through the wheel positioning device without falling into the opening 12, thereby reducing the bumpy feeling of the rear wheels when passing through the wheel positioning device, greatly improving the experience. Even if the driving component fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression will always exist and cannot be flattened, so at least the positioning function can be achieved; at the same time, it has the advantages of simple control and high stability, and the moving force is more stable, which prolongs the service life.

[0112] The vehicle positioning control method may further include the following steps:

[0113] Step 202: After the rear wheels of the vehicle leave the limiting device 1 corresponding to the front wheel parking place, the driving cover plate 2 moves to be exposed at the opening 12 corresponding to the front wheel parking place.

[0114] In this step, after the rear wheels of the vehicle leave the limiting device 1 corresponding to the front wheel parking place, the cover plate 2 is driven to move by the driving assembly so that the cover plate 2 is exposed at the opening 12 corresponding to the front wheel parking place, so that the front wheels of the next vehicle will be located between the two positioning inclined surfaces 11 when entering the wheel positioning device. The two positioning inclined surfaces 11 are used to limit the two movement trends of the front wheels of the vehicle, namely forward and backward, respectively, so that the front wheels of the vehicle are limited between the two positioning inclined surfaces 11, thereby achieving precise positioning and avoiding vehicle displacement during battery replacement operation.

[0115] Example 4

[0116] like Figure 6 As shown, in this embodiment, a vehicle positioning control method is disclosed, which is used in the above-mentioned station change, and the wheel positioning device is installed at the position where the rear wheels of the corresponding vehicle are parked, that is, the limiting device 1 is installed at the position where the rear wheels of the corresponding vehicle are parked. The vehicle positioning control method includes the following steps:

[0117] Step 301: Before the front wheels of the vehicle enter the limiting device 1 of the corresponding rear wheel parking place, the driving cover plate 2 moves to cover the opening 12 of the corresponding rear wheel parking place.

[0118] In this step, before the front wheel of the vehicle enters the limiting device 1 corresponding to the rear wheel parking place, the cover plate 2 is driven to move by the driving component, so that the cover plate 2 will block the opening 12 corresponding to the rear wheel parking place, and then the front wheel of the vehicle will walk on the cover plate 2 when passing through the wheel positioning device without falling into the opening 12, thereby reducing the bumpy feeling of the front wheel when passing through the wheel positioning device, greatly improving the experience. Even if the driving component fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression will always exist and cannot be flattened, so at least the positioning function can be achieved; at the same time, it has the advantages of simple control and high stability, and the moving force is more stable, which prolongs the service life.

[0119] The vehicle positioning control method may further include the following steps:

[0120] Step 302: Before the rear wheels of the vehicle enter the limiting device 1 of the corresponding rear wheel parking place, the driving cover plate 2 moves to be exposed at the opening 12 of the corresponding rear wheel parking place.

[0121] In this step, before the rear wheels of the vehicle enter the limiting device 1 corresponding to the rear wheel parking place, the front wheels of the vehicle have passed the limiting device 1 corresponding to the rear wheel parking place, and the cover plate 2 is driven to move by the driving component so that the cover plate 2 is exposed at the opening 12 corresponding to the rear wheel parking place. The rear wheels of the vehicle will be located between the two positioning inclined surfaces 11 when entering the wheel positioning device. The two positioning inclined surfaces 11 are used to limit the two movement trends of the rear wheels of the vehicle, namely, forward and backward, respectively, so that the rear wheels of the vehicle are limited between the two positioning inclined surfaces 11, thereby achieving precise positioning and avoiding vehicle displacement during battery replacement operation.

[0122] Example 5

[0123] like Figure 7 As shown, in this embodiment, a vehicle positioning control method is disclosed, and the vehicle positioning control method is used in the above-mentioned station change, and the wheel positioning device is installed at the position corresponding to the parking position of the front wheel of the vehicle and the position corresponding to the parking position of the rear wheel of the vehicle, that is, the limiting device 1 is installed at the position corresponding to the parking position of the front wheel of the vehicle and the position corresponding to the parking position of the rear wheel of the vehicle. The vehicle positioning control method includes the following steps:

[0124] Step 401: before the front wheels of the vehicle enter the limiting device 1 corresponding to the rear wheel parking place, drive the cover plate 2 corresponding to the rear wheel parking position of the vehicle to move and cover the opening 12 of the corresponding rear wheel parking place.

[0125] In this step, before the front wheel of the vehicle enters the limiting device 1 corresponding to the rear wheel parking place, the cover plate 2 is driven to move by the driving component, so that the cover plate 2 will block the opening 12 of the corresponding rear wheel parking place, and then the front wheel of the vehicle will walk on the cover plate 2 when passing through the wheel positioning device corresponding to the rear wheel parking place without falling into the opening 12, thereby reducing the bumpy feeling when the front wheel passes through the wheel positioning device corresponding to the rear wheel parking place, greatly improving the experience. Even if the driving component fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression will always exist and cannot be flattened, so at least the positioning function can be achieved; at the same time, it has the advantages of simple control and high stability, and the moving force is more stable, which prolongs the service life.

[0126] Step 402: After the front wheels of the vehicle leave the limiting device 1 corresponding to the rear wheel parking place, the cover plate 2 corresponding to the rear wheel parking place of the vehicle is driven to move and expose the opening 12 of the corresponding rear wheel parking place.

[0127] In this step, after the front wheels of the vehicle leave the limiting device 1 corresponding to the rear wheel parking place, the rear wheels of the vehicle have not entered the limiting device 1 corresponding to the rear wheel parking place, and the cover plate 2 is driven to move by the driving component so that the cover plate 2 is exposed at the opening 12 of the corresponding rear wheel parking place. When the rear wheels of the vehicle enter the wheel positioning device corresponding to the rear wheel parking place, they will be located between the two positioning inclined surfaces 11. The two positioning inclined surfaces 11 are respectively used to limit the two movement trends of the rear wheels of the vehicle forward and backward, so that the rear wheels of the vehicle are limited between the two positioning inclined surfaces 11, thereby achieving precise positioning and avoiding vehicle displacement during battery replacement operation.

[0128] Step 403 , after the vehicle reaches the switching point of the switching station body 10 and is lifted, the cover plates 2 corresponding to the parking position of the front wheels of the vehicle and the parking position of the rear wheels of the vehicle are driven to move and cover the opening 12 respectively.

[0129] In this step, after the vehicle reaches the switching point of the switching station body 10 and is lifted, the cover plate 2 is driven to move by the driving assembly, so that the cover plate 2 will block the opening 12 corresponding to the parking position of the front wheel of the vehicle and the parking position of the rear wheel of the vehicle. The front and rear wheels of the vehicle will walk on the cover plate 2 when passing through the wheel positioning device without falling into the opening 12, thereby reducing the bumpy feeling of the front and rear wheels when passing through the wheel positioning device, greatly improving the experience. Even if the driving assembly fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression will always exist and cannot be flattened, so at least the positioning function can be achieved; at the same time, it has the advantages of simple control and high stability, and the moving force is more stable, which prolongs the service life.

[0130] Step 404: After the rear wheel of the vehicle leaves the limiting device 1 corresponding to the front wheel parking place, the cover plate 2 corresponding to the parking position of the front wheel of the vehicle is driven to move and be exposed at the opening 12 of the corresponding front wheel parking place.

[0131] In this step, after the rear wheel of the vehicle leaves the limiting device 1 corresponding to the parking position of the front wheel, the next vehicle will change the station body 10. Since the cover plate 2 will block the opening 12 of the parking position of the rear wheel of the corresponding vehicle, the front wheel reduces the bumpy feeling when passing through the cover plate 2 of the parking position of the rear wheel of the corresponding vehicle, which greatly improves the experience. Even if the drive component fails, the positioning slope 11 will always be in a downward tilted state, that is, the depression always exists and cannot be flattened, so at least the positioning function can be achieved. Before the front wheel of the next vehicle enters the wheel positioning device where the front wheel of the corresponding vehicle is parked, the cover plate 2 is driven by the drive component to move, so that the cover plate 2 is exposed at the opening 12 of the parking position of the front wheel of the corresponding vehicle, so that the front wheel of the next vehicle will be located between the two positioning slopes 11 when entering the wheel positioning device, and the two positioning slopes 11 are used to limit the two movement trends of the front wheel of the vehicle forward and backward, so that the front wheel of the next vehicle is limited between the two positioning slopes 11, thereby achieving precise positioning and avoiding vehicle displacement during battery replacement operation.
