Description

[0001] This application is a division of a Chinese invention patent with an application date of March 26, 2021, application number 202110326921.7, and name “Wheel positioning device, replacement platform and control method for replacing platform in battery swap station”. Technical Field

[0002] The invention relates to a wheel positioning device, a replacement platform and a control method for a replacement platform of a battery swap station. Background Art

[0003] 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.

[0004] 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 from the vehicle loading 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.

[0005] In the patent document with the patent authorization announcement number CN211765460U, the driving mechanism drives two blocking members to open or close in different directions through a transmission mechanism, thereby forming a wheel limiting space and preventing the vehicle from being bumped. The driving mechanism described in the patent document uses a push rod to drive the opening and closing of the blocking member, and the push rod is connected to one end of the blocking member. Under the action of the push rod, the blocking member rotates along the opposite end of the push rod, and a rotation connection is adopted between the push rod and the blocking member. However, after the push rod drives the blocking member to rotate in place, the blocking member is kept stationary entirely by the thrust of the push rod in a static state, making the push rod easy to be damaged, and the blocking member cannot be locked, and it is easy to lose the limiting effect on the wheel when the push rod fails. At the same time, each blocking member in the patent document needs to be driven by two push rods to open and close, which is prone to asynchronous situations, resulting in poor positioning accuracy of the vehicle. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects that the push rod of the existing vehicle positioning device is easily damaged, the blocking member cannot be locked, the limiting effect on the wheel is easily lost when the push rod fails, and the situation of being out of sync is easy to occur, resulting in poor positioning accuracy of the vehicle. A wheel positioning device, a replacement platform and a control method for a replacement platform in a battery swap station are provided.

[0040] A vehicle positioning control method is used for the replacement platform as described above, and the vehicle positioning control method comprises the following steps:

[0041] Before the vehicle enters or exits the replacement platform body, the driving assembly drives the rear limit block to rotate or move, lowering the height protruding from the upper surface of the replacement platform body so that the vehicle can pass over the rear limit block;

[0043] In this solution, the front limit block and / or the rear limit block are driven to rotate or move downward, thereby reducing the height of the limit block protruding from the upper surface of the replacement platform body. When the wheel passes through the rear limit block and enters the wheel alignment device, the bumpy feeling is effectively reduced, greatly improving the experience.

[0069] Wheel 20 DETAILED DESCRIPTION

[0070] 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.

[0071] Example 1

[0072] like Figure 1 , Figure 2 and Figure 3 As shown, the replacement platform of the embodiment of the present invention includes a wheel positioning device for the replacement platform of the battery swap station and a replacement platform body 10. The wheel positioning device is arranged on the replacement platform body 10, and the wheel positioning device is installed at the position where the wheel 20 of the corresponding vehicle is parked.

[0073] The wheel positioning device for a replacement platform in a battery swap station includes a limiting device 1, which includes two limiting blocks 11. The two limiting blocks 11 are both used to be installed on the replacement platform body 10 and protrude from the upper surface of the replacement platform body 10. The two limiting blocks 11 are respectively used to limit the two movement trends of the vehicle's wheels 20 forward and backward, so that the vehicle's wheels 20 are limited between the two limiting blocks 11.

[0074] The wheel alignment device further includes a driving assembly 2 and / or an elastic assembly 3. The driving assembly 2 is used to drive at least one of the two limiting blocks 11 to rotate or move so as to reduce the height protruding from the upper surface of the replacement platform body 10. The elastic assembly 3 is used to push the limiting block 11 to rotate or move upward to reset when the limiting block 11 is driven by the vehicle to reduce the height protruding from the upper surface of the replacement platform body 10.

[0075] The limiting device 1 is installed at the position corresponding to the parking position of the wheel 20 of the vehicle. Before the wheel 20 of the vehicle enters the wheel alignment device, the driving assembly 2 provides a force to act on the limit block 11, so that the limit block 11 rotates or moves downward, thereby reducing the height of the limit block 11 protruding from the upper surface of the replacement platform body 10. When the wheel 20 passes through the limit block 11 and enters the wheel alignment device, the bumpy feeling is effectively reduced, greatly improving the experience.

[0076] After the wheel 20 of the vehicle reaches the switching potential, the driving component 2 provides a force to act on the limit block 11, so that the limit block 11 rotates or moves upward, and / or the elastic component 3 applies a force to the limit block 11, so that the limit block 11 is pushed to rotate or move upward to reset, so that the two limit blocks 11 are limited against the wheel 20, thereby realizing the precise positioning of the wheel 20.

[0077] Before the wheel 20 of the vehicle drives out of the wheel alignment device, the driving component 2 provides a force to act on the limit block 11, so that the limit block 11 rotates or moves downward, thereby reducing the height of the limit block 11 protruding from the upper surface of the replacement platform body 10. When the wheel 20 passes through the limit block 11 and drives into the wheel alignment device, the bumpy feeling is effectively reduced, which greatly improves the experience. Of course, the wheel 20 of the vehicle can directly pass through and apply a downward force to the limit block 11. The elastic component 3 has an elastic function and can shrink and deform, so that the limit block 11 rotates or moves downward, thereby reducing the height of the limit block 11 protruding from the upper surface of the replacement platform body 10, effectively reducing the bumpy feeling, and greatly improving the experience. At the same time, the elastic component 3 also has a reset function to increase the sensitivity of the limit block 11 to rotate or move downward with the driving component 2, or play a supplementary role when the reset pulling force of the driving component 2 on the limit block 11 is insufficient, so as to ensure that the limit block 11 rotates or moves downward, and ensure that the wheel 20 passes through the limit block 11 to effectively reduce the bumpy feeling, which greatly improves the experience. Furthermore, the elastic component 3 is extended and retracted as the wheel 20 rolls, and no additional power source is required, which reduces the cost.

[0078] The limit block 11 is driven to rotate or move by the driving component 2 and / or the elastic component 3, so that the height of the limit block 11 protruding from the upper surface of the replacement platform body 10 is lowered when the vehicle passes through, thereby effectively reducing the bumpy feeling when the vehicle passes through the limiting device 1, greatly improving the experience; and the elastic component 3 is extended and retracted with the rolling of the wheel 20, without the need to set up an additional power source, and the cost is low; at the same time, it has the advantages of simple control and high stability, effectively avoiding the deviation and dislocation of the limit block 11 during rotation or movement, and greatly improving the safety and reliability of the wheel positioning device.

[0079] In one embodiment, the limiting device 1 is installed at a position corresponding to the parking position of the front wheels of the vehicle. In another embodiment, the limiting device 1 can be installed at a position corresponding to the parking position of the rear wheels of the vehicle. Of course, there can be multiple limiting devices 1, and multiple limiting devices 1 are respectively installed at the positions corresponding to the parking positions of the front wheels and rear wheels of the vehicle.

[0080] The wheel alignment device also includes a limiting component 4, which is connected to at least one of the two limiting blocks 11 and can limit the rotation or movement of the limiting block 11. When the drive assembly 2 and / or the elastic assembly 3 apply an upward force to the two limiting blocks 11, the two limiting blocks 11 protrude from the height of the upper surface of the replacement platform body 10 and are used to accurately position the wheel 20. At this time, the movement of the limiting block 11 is limited by the limiting component 4 to prevent the limiting block 11 from rotating or moving downward when the drive assembly 2 fails or fails, thereby losing the positioning effect on the wheel 20. At the same time, the limiting component 4 can share a part of the force of the drive assembly 2 or the elastic assembly 3. Therefore, the setting of the limiting component 4 ensures the limiting effect of the wheel alignment device on the wheel 20, greatly improves the safety and stability of the wheel alignment device, and also makes the drive assembly 2 or the elastic assembly 3 less likely to be damaged.

[0081] The limiting component 4 can move relative to the replacement platform body 10 and is used to connect or disconnect with the limit block 11. When the limiting component 4 is connected with the limit block 11, the limiting component 4 will limit the rotation or movement of the limit block 11, effectively avoiding the displacement and dislocation of the limit block 11 during use, and further ensuring the limiting effect of the wheel alignment device on the wheel 20. When the limiting component 4 is disconnected from the limit block 11, the driving component 2 and / or the elastic component 3 apply a downward force to the limit block 11, so that the limit block 11 rotates or moves downward, thereby reducing the height of the limit block 11 protruding from the upper surface of the replacement platform body 10. When the wheel 20 passes through the limit block 11 and enters the wheel alignment device, the bumpy feeling is effectively reduced, which greatly improves the experience. By moving the limiting component 4, the limit block 11 is connected or disconnected with the limit block 11, thereby realizing the restricted movement of the limit block 11 or reducing the height of the limit block 11 protruding from the upper surface of the replacement platform body 10, which is very convenient to use and has high stability.

[0082] The limiting component 4 is configured to be pulled out of the limit block 11 before the drive component 2 is driven and / or before the elastic component 3 is compressed, and to be inserted into the limit block 11 after the drive component 2 or the elastic component 3 is reset. Before the drive component 2 is driven and / or before the elastic component 3 is compressed, the limiting component 4 is pulled out of the limit block 11, so that the limiting component 4 and the limit block 11 are disconnected from each other, so that the drive component 2 can drive the limit block 11 to move or the elastic component 3 and the limit block 11 to rotate or move downward, thereby ensuring the stability of the wheel alignment device. After the drive component 2 or the elastic component 3 is reset, the limiting component 4 is inserted into the limit block 11, so that the limiting component 4 and the limit block 11 are connected to each other, effectively avoiding the limit block 11 from being offset and misaligned, and greatly improving the safety and stability of the wheel alignment device. At the same time, the structure is simple and very convenient to use.

[0083] In one embodiment, the driving assembly 2 includes at least one driving member, which is connected to the limit block 11, and is used to pull the limit block 11 to rotate downward along the side connected to the replacement platform body 10, so that the limit block 11 is not higher than or flush with the upper surface of the replacement platform body 10. The driving member is used to provide driving force and directly act on the limit block 11, and the limit block 11 rotates downward on the replacement platform body 10, so that the limit block 11 is not higher than or flush with the upper surface of the replacement platform body 10, effectively reducing the bumpy feeling or even eliminating the bumpy feeling, greatly improving the experience.

[0084] In another embodiment, the driving member is connected to the limit block 11, and the driving member is used to pull the limit block 11 downward so that the limit block 11 is not higher than or flush with the upper surface of the replacement platform body 10. The driving member is used to provide driving force and directly act on the limit block 11, and the limit block 11 moves downward relative to the replacement platform body 10, so that the limit block 11 is not higher than or flush with the upper surface of the replacement platform body 10, effectively reducing the bumpy feeling or even eliminating the bumpy feeling, greatly improving the experience.

[0085] The driving member includes a telescopic rod 22 and a power unit 21. One end of the telescopic rod 22 is connected to the limit block 11. The power unit 21 drives the telescopic rod 22 to extend and retract to drive the limit block 11 to rotate or move. The power unit 21 is used to provide driving force and act on the telescopic rod 22, and the limit block 11 is driven to rotate or move together through the telescopic rod 22. The structure is simple and easy to install.

[0086] In this embodiment, the power unit 21 is a cylinder. In other embodiments, the power unit 21 may be an oil cylinder. The power unit 21 uses an oil cylinder or an air cylinder, so that the wheel 20 is subjected to a gentler force, and has the characteristics of simple structure, reliable operation, and easy installation and maintenance. Of course, the drive assembly 2 may also be a structure such as an electric push rod, an air bag, etc. that can drive the limit block 11 to rotate or move. Therefore, a suitable power unit 21 can be selected according to space, cost, etc.

[0087] In one embodiment, the elastic component 3 includes an elastic member 31, which is connected to the limit block 11. The elastic member 31 is used to push the limit block 11 to rotate upward along the side connected to the replacement platform body 10, so that the limit block 11 is higher than the upper surface of the replacement platform body 10. The elastic member 31 has a simple structure and has a reset function. It does not require an external power source. The elastic member 31 is compressed and deformed and directly acts on the limit block 11, so that the limit block 11 rotates upward on the replacement platform body 10, so that the limit block 11 is higher than the upper surface of the replacement platform body 10 and abuts against the wheel 20. Then, the limiting component 4 is inserted into the limit block 11 and has a limiting effect on the limit block 11, thereby achieving accurate positioning of the wheel 20.

[0088] In another embodiment, the elastic member 31 is connected to the limit block 11, and the elastic member 31 is used to push the limit block 11 to move upward so that the limit block 11 is higher than the upper surface of the replacement platform body 10. The elastic member 31 has a reset function, and the elastic member 31 is compressed and deformed and directly acts on the limit block 11. The limit block 11 moves upward relative to the replacement platform body 10, so that the limit block 11 is higher than the upper surface of the replacement platform body 10 and abuts against the wheel 20. Then, the limiting component 4 is inserted into the limit block 11 and has a limiting effect on the limit block 11, thereby realizing accurate positioning of the wheel 20. Preferably, the elastic member 31 is a spring cylinder or a pneumatic cylinder. It is small in size and occupies little space; it has a large elastic force and high stability.

[0089] In this embodiment, the two limit blocks 11 are respectively a front limit block and a rear limit block, the front limit block is used to limit the forward movement tendency of the vehicle's wheel 20, and the rear limit block is used to limit the backward movement tendency of the vehicle's wheel 20; the number of limiting components 4 is two, and the two limiting components 4 are respectively used to limit the rotation or movement of the front limit block and the rear limit block; the front limit block is connected to an elastic member 31, and the rear limit block is connected to a driving member, and the front limit block and the rear limit block rotate in opposite directions. By setting the front limit block and the rear limit block to rotate in opposite directions, the front limit block can be rotated or moved downward under the drive of the wheel 20, so the front limit block can be connected to an elastic member 31 that can only rotate or move upward to achieve its reset; and when the wheel 20 enters the limiting device 1 and touches the front limit block, the front limit block will generate a backward force on the wheel 20, so that the wheel 20 cannot be accurately parked at the preset position. At this time, the rear limit block needs to apply a forward force to the wheel 20, so the rear limit block is connected to a driving member, which can facilitate the fine adjustment of the parking position of the wheel 20 in the front and rear directions when the wheel 20 is not accurately parked. Such a configuration has a simple structure, low cost, and convenient installation and setting. Of course, in other embodiments, the front limit block and the rear limit block can also move in the same direction.

[0090] In one embodiment, the front limit block and the rear limit block are respectively connected to a driving member, and the two driving members are used to drive the front limit block and the rear limit block to rotate or move respectively. The front limit block and the rear limit block are respectively rotated or moved upward or downward by the driving member, and the stability is high.

[0091] In another embodiment, the front limit block and the rear limit block are respectively connected to an elastic member 31, and the front limit block and the rear limit block rotate or move in the same direction when the vehicle is driven. The front limit block and the rear limit block are respectively rotated or moved upwards by the elastic member 31 to reset, and the rotation or movement of the front limit block and the rear limit block are restricted by the limiting component 4, and reset is automatically achieved, which is very convenient to use and has a simple structure.

[0092] The cross section of the stopper 11 along the front-rear direction of the vehicle is triangular, so that the stopper 11 protruding from the upper surface of the replacement platform body 10 has an inclined surface facing the wheel 20, and has a limiting effect on the wheel 20 through the inclined surface; at the same time, when the wheel 20 passes through the stopper 11, the stopper 11 is driven to rotate or move downward, so that one plane of the stopper 11 is kept as flush as possible with the surface of the replacement platform body 10, which is very convenient to use.

[0093] In this embodiment, both of the two limiting blocks 11 have limiting surfaces for limiting the position of the wheels 20 of the vehicle. The limiting surfaces are limited against the wheels, thereby achieving the positioning of the wheels. The limiting blocks 11 are driven to rotate or move by the driving component 2 and / or the elastic component 3 to achieve the change of the inclination angle between the limiting surfaces and the upper surface of the replacement platform body 10. The structure is simple and very convenient to use.

[0094] Among them, the limiting surface can be provided with a ball or a roller whose axis is perpendicular to the vehicle's driving direction. When positioning the wheel, the two limiting surfaces are used to limit the wheel 20 of the vehicle, and the ball or roller facilitates the wheel 20 to move on the limiting surface, making it easy to adjust the wheel 20 to achieve precise positioning.

[0095] In this embodiment, the side of the two limit blocks 11 that are close to each other is rotatably connected to the replacement platform body 10. When the limit block 11 located behind the wheel 20 moves upward or rotates after the wheel enters the limiting device 1, or when the wheel 20 is about to leave the limiting device 1 and the two limit blocks 11 move downward or rotate, the movement or rotation of the limit block 11 will not interfere with the wheel 20. The rotation connection method is adopted to realize the upward or downward movement or rotation of the limit block 11, which is very convenient for installation. Of course, in other embodiments, the limit block 11 can be lifted and lowered relative to the replacement platform body 10.

[0096] The limit block 11 is rotatably connected to the replacement platform body 10 through a rotating pin. The limit block 11 is rotatably connected to the replacement platform body 10 through the rotating pin, so that the limit block 11 and the replacement platform body 10 are rotatably connected, which is very convenient to install and has low cost.

[0097] Example 2

[0098] like Figure 4 As shown, the embodiment of the present invention further discloses a vehicle positioning control method, which is used for the replacement platform as described above, and the vehicle positioning control method comprises the following steps:

[0099] Step 101: before the vehicle enters the replacement position of the replacement platform body 10, the driving assembly 2 drives the rear limit block to rotate or move, and lowers the height protruding from the upper surface of the replacement platform body 10 so that the vehicle can pass over the rear limit block;

[0100] Step 102, after the vehicle reaches the replacement point of the replacement platform body 10, the rear limit block is driven to rotate or move to reset and position the vehicle;

[0101] Step 103 , when the vehicle drives out of the replacement platform body 10 , the front limit block is driven to rotate or move, so as to reduce the height of the upper surface protruding from the replacement platform body 10 , so that the vehicle can pass over the front limit block.

[0102] In this embodiment, the wheel alignment device is installed at the parking position of the wheel 20 of the corresponding vehicle. Before the vehicle enters the replacement platform body 10, the control drive assembly 2 is used to drive the rear limit block to rotate or move downward, thereby reducing the height of the limit block protruding from the upper surface of the replacement platform body 10. When the wheel 20 passes through the rear limit block and enters the wheel alignment device, the bumpy feeling is effectively reduced, which greatly improves the experience. After the vehicle reaches the replacement platform body 10, the rear limit block is driven to rotate or move upward to reset, so that the front limit block and the rear limit block will be limited against the wheel 20, thereby realizing the precise positioning of the wheel 20. When the vehicle exits the replacement platform body 10, the front limit block is first driven to rotate or move downward to reduce the height protruding from the upper surface of the replacement platform body 10 so that the vehicle can pass over the front limit block. At the same time, it has the advantages of simple control and high stability, effectively avoiding the deviation and dislocation of the limit block 11 during the rotation or movement process, and greatly improving the safety and reliability of the wheel alignment device.

[0103] In other embodiments, in step 103, when the vehicle drives out of the replacement platform body 10, the rear limit block can also be driven to rotate or move, reducing the height of the upper surface protruding from the replacement platform body 10 so that the next vehicle can pass over the rear limit block, effectively reducing the bumpy feeling and greatly improving the experience.

[0104] In one embodiment, before a vehicle drives out of the replacement platform body 10, the driving assembly 2 drives the rear limit block to rotate or move, reducing the height of the upper surface protruding from the replacement platform body 10 so that the next vehicle can pass over the rear limit block, effectively reducing the bumpy feeling and greatly improving the experience.

[0105] In another embodiment, when a vehicle enters the replacement platform body 10, the rear limit block is driven to rotate or move, reducing the height of the upper surface protruding from the replacement platform body 10 so that the vehicle can pass over the front limit block, effectively reducing the bumpy feeling and greatly improving the experience.

[0106] Before the vehicle enters the replacement position of the replacement platform body 10, the limiting component 4 connected to the rear limit block is first pulled out, and then the rear limit block is driven to rotate or move. Before step 101, the limiting component 4 is pulled out of the rear limit block, so that the limiting component 4 and the rear limit block are disconnected from each other, so that the driving component 2 can drive the rear limit block to rotate or move downward, ensuring the stability of the wheel alignment device, effectively reducing the bumpy feeling, and greatly improving the experience.

[0107] After the vehicle reaches the replacement point of the replacement platform body 10, the rear limit block 11 is first driven to rotate or move to reset, and then the limiting component 4 is inserted and connected to the rear limit block. After step 102 and before step 103, by inserting the limiting component 4 into the rear limit block, the limiting component 4 and the rear limit block are connected to each other and the limiting effect on the rear limit block is achieved. After that, the vehicle is replaced, effectively avoiding the displacement and misalignment of the rear limit block, ensuring the limiting effect of the rear limit block on the wheel 20, achieving accurate positioning of the wheel 20, and greatly improving the safety and stability of the wheel positioning device.

[0108] Before the vehicle drives out of the battery replacement platform body 10, the limiting components 4 connected to the front limit block and the rear limit block are pulled out respectively, and then the rear limit block is driven to rotate or move. After the battery replacement operation is completed on the vehicle, the limiting component 4 is pulled out of the front limit block and the rear limit block, so that the limiting component 4 is disconnected from the front limit block and the rear limit block, so that the driving component 2 can drive the rear limit block to rotate or move downward, so that the next vehicle can pass the rear limit block, effectively reducing the bumpy feeling and greatly improving the experience.

[0109] In this embodiment, the front limit block is connected to the elastic component 3, the wheel 20 can directly pass through the front limit block and apply a downward force to the front limit block, and the elastic component 3 can shrink and deform, thereby reducing the height of the front limit block protruding from the upper surface of the replacement platform body 10, effectively reducing the bumpy feeling and greatly improving the experience.

[0110] After the vehicle leaves the replacement platform body 10, the limiting component 4 is inserted and connected to the front limit block. After step 103, the elastic component 3 has a reset function and applies a force to the front limit block, so as to push the front limit block to rotate or move upward to reset. After resetting, by inserting the limiting component 4 into the front limit block, the limiting component 4 and the front limit block are connected to each other and the limiting function of the front limit block is realized, thereby realizing the limiting function of the next vehicle, realizing the precise positioning of the wheel 20, and greatly improving the safety and stability of the wheel alignment device.

[0111] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
