Description

[0001] This application is a divisional application of the patent application with the application date of September 3, 2020, application number 2020109176283, and invention name "Vehicle-carrying platform and battery swap station including the same". Technical Field

[0002] The present invention relates to the field of battery swap stations for electric vehicles, and in particular to a vehicle carrying platform and a battery swap station comprising the same. Background Art

[0003] The battery swap station is used to replace batteries in electric vehicles. After the car enters the battery swap station and is stably positioned, the battery swap equipment of the battery swap station drives from the charging room into the battery swap room and replaces the battery of the electric vehicle.

[0004] However, existing battery swap stations are typically only capable of swapping batteries for a single model of electric vehicle. If a different model is used, due to differences in wheelbase and track dimensions, existing battery swap stations are often unable to reliably locate and secure the vehicle, making battery swapping impossible. Therefore, existing technologies require dedicated battery swap stations for different models of electric vehicles, significantly increasing battery swap costs. Furthermore, when using existing battery swap stations to swap batteries for electric vehicles, the reliability of positioning the electric vehicles is relatively low. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a vehicle carrying platform and a battery swap station including the same.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A vehicle carrying platform is characterized in that it comprises:

[0008] Platform itself;

[0009] The vehicle loading platform further includes at least one of a first rear wheel positioning device for positioning a first side rear wheel of the electric vehicle, a first front wheel positioning device for positioning a first side front wheel of the electric vehicle, a second rear wheel positioning device for positioning a second side rear wheel of the electric vehicle, and a second front wheel positioning device for positioning a second side front wheel of the electric vehicle when the electric vehicle drives into the battery swapping position along a preset path;

[0010] The vehicle-carrying platform further includes a plurality of moving parts, and the plurality of moving parts are used to implement at least one of the following (1)-(5):

[0011] (1) for driving the first rear wheel alignment assembly of the first rear wheel alignment device to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path;

[0012] (2) used to drive the front positioning assembly and the rear positioning assembly of the first front wheel alignment device to move in a direction parallel to the preset path and / or a direction perpendicular to the preset path;

[0013] (3) used to drive the left positioning assembly and / or the right positioning assembly of the first front wheel positioning device to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path;

[0014] (4) for driving the second rear wheel alignment assembly of the second rear wheel alignment device to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path;

[0015] (5) Used to drive the second front wheel alignment device to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path.

[0016] In this solution, the platform body is used to carry the electric vehicle, and the first rear wheel positioning component of the first rear wheel positioning device, the front positioning component and the rear positioning component of the first front wheel positioning device, the left positioning component and / or the right positioning component of the first front wheel positioning device, the second rear wheel positioning component and the second front wheel positioning device of the second rear wheel positioning device are movable respectively under the action of the moving parts, so that the movement of the above-mentioned positioning components or positioning devices can be achieved by operating the moving parts according to actual needs, so that the vehicle-carrying platform can be suitable for the positioning and battery replacement needs of electric vehicles of different models (such as different wheelbases and different track widths), which is conducive to reducing the overall battery replacement cost.

[0017] Preferably, the vehicle carrying platform further comprises a first guiding device, which is provided on the platform body along a first side of the platform body and is used to guide the wheels on the first side of the electric vehicle so that the electric vehicle drives along a preset path into the battery swapping position;

[0018] Preferably, the first guide device comprises two first guide components arranged opposite to each other, and both of the first guide components are inclined in a direction away from the first side wheel;

[0019] Wherein, along the direction of the preset path, the distance between the two first guide components gradually decreases;

[0020] Preferably, the first guide assembly includes a first guide roller, and the first guide roller is configured to be axially rotatable so that the first side wheel can be constrained between two first guide rollers when driving in.

[0021] In this embodiment, the first guide device guides the first wheel of the electric vehicle, ensuring that the electric vehicle follows a predetermined path to the battery swapping location. The first guide assembly is tilted away from the first wheel, forming an "outward eight" shape. This arrangement allows for a greater distance between the two first guide assemblies near the vehicle's entrance, facilitating easier entry of electric vehicles of varying sizes (e.g., wheel widths) into the first guide device. Furthermore, the distance between the two first guide assemblies is smaller at the end farther from the vehicle's entrance, enhancing guidance for the first wheel, ensuring reliable positioning and ensuring the vehicle follows the predetermined path to the battery swapping location. When the first wheel enters between the two first guide assemblies, the first guide roller rotates axially. The interaction between the first guide roller and the first wheel causes the wheel to move, guiding it to the desired position. The use of the first guide roller ensures convenient and reliable guidance of the first wheel.

[0022] Preferably, along the direction of the preset path, the first guiding device and the first rear wheel positioning device are arranged in sequence;

[0023] The first rear wheel alignment device includes a first rear wheel alignment component provided on one side of the parking position of the first rear wheel, and an extension direction of the first rear wheel alignment component is parallel to a direction of the preset path.

[0024] In this solution, the first-side rear wheel is guided to the first rear wheel alignment device by the first guiding device. Under the action of the first rear wheel alignment assembly, the first-side rear wheel can be positioned in the first rear wheel alignment device.

[0025] Preferably, the first rear wheel positioning device includes two first rear wheel positioning components relatively arranged on both sides of the parking place of the first side rear wheel, and the two first rear wheel positioning components position the first side rear wheel in a left and right direction perpendicular to the direction of the preset path.

[0026] In this solution, the first side rear wheel is guided to the first rear wheel positioning device by the first guide device. Under the action of the relatively arranged first rear wheel positioning assembly, the two sides of the first side rear wheel are positioned respectively, so that the first side rear wheel can be positioned in the first rear wheel positioning device more reliably.

[0027] Preferably, along the direction of the preset path, the distance between the first rear wheel positioning device and the first guiding device is greater than or equal to 0 and is smaller than the diameter of the first side rear wheel.

[0028] In this embodiment, the first rear wheel alignment device can be in direct contact with the first guide device, i.e., the distance between the first rear wheel alignment device and the first guide device is zero, or a gap greater than zero and less than the diameter of the first rear wheel is formed between the first rear wheel alignment device and the first guide device. When the distance is zero, a first wheel of the electric vehicle that has left a portion of the first guide device can directly enter the first rear wheel alignment device, making it less likely for the first wheel to deviate again and facilitating more reliable positioning of the first wheel. When the distance is greater than zero, it should be less than the diameter of the first rear wheel. This is because if the distance is too large (e.g., greater than the diameter of the first rear wheel), after a wheel of the first wheel leaves the first guide device, it may not yet be in contact with the first rear wheel alignment device. In this case, the wheel may deviate, affecting the reliability of the wheel's positioning. With this arrangement, when the first wheel leaves the first guide device, at least a portion of the first wheel is already in contact with the first rear wheel alignment device, facilitating positioning of the first wheel and improving the reliability of the first wheel's positioning.

[0029] Preferably, the first rear wheel alignment assembly includes a first rear wheel alignment roller, and the first rear wheel alignment roller is configured to be axially rotatable so that the first side rear wheel can be constrained between two first rear wheel alignment rollers when driving in.

[0030] In this embodiment, when the first-side rear wheel enters the first rear wheel alignment assembly, the two first rear wheel alignment rollers can rotate axially. The two first rear wheel alignment rollers interact with both sides of the first-side rear wheel, thereby causing the first-side rear wheel to move and position the first-side rear wheel to a desired position. The use of the first rear wheel alignment rollers can more conveniently and reliably achieve the positioning of the first-side rear wheel. If the position of the first-side rear wheel deviates from the desired position, the first rear wheel can be more conveniently and reliably corrected under the action of the first rear wheel alignment rollers.

[0031] Preferably, the first guide roller comprises a first guide roller portion and a second guide roller portion sequentially connected along the direction of the preset path, and the cross-sectional size of the first guide roller portion gradually increases along the direction of the preset path;

[0032] The first rear wheel alignment roller includes a first rear wheel alignment roller portion and a second rear wheel alignment roller portion sequentially connected along the preset path, and a cross-sectional size of the first rear wheel alignment roller portion gradually increases along the preset path.

[0033] In this embodiment, the structural characteristics of the first guide roller portion and the first rear wheel positioning roller portion enable them to also serve as guides. Specifically, the first guide roller portion allows the first side wheel to be more conveniently guided from the first guide roller portion to the second guide roller portion, while the first rear wheel positioning roller portion further guides the first side wheel after it leaves the first guide device, thereby improving the reliability and efficiency of positioning the wheel on one side of the electric vehicle.

[0034] Preferably, the first guide roller portion and the first rear wheel positioning roller portion are tapered rollers, and the second guide roller portion and the second rear wheel positioning roller portion are cylindrical rollers.

[0035] In this solution, on the one hand, the conical roller can play the above-mentioned guiding role, and the cylindrical roller can guide or straighten the wheel on the first side; on the other hand, the outer surfaces of the conical roller and the cylindrical roller are curved surfaces with basically no sharp edges, which are not easy to cause damage to the wheel on the first side, and are beneficial to protecting the wheel on the first side.

[0036] Preferably, the distance between the two first rear wheel alignment assemblies is greater than the width of the first side rear wheel.

[0037] In this solution, a gap greater than 0 is left between the two first rear wheel alignment assemblies and the first side rear wheel. In this arrangement, when the electric vehicle needs to move, the above gap ensures that the first rear wheel alignment assemblies will not hinder the movement of the first side rear wheel.

[0038] Preferably, along the direction of the preset path, the first guiding device, the first rear wheel positioning device and the first front wheel positioning device are arranged in sequence.

[0039] In this solution, through the cooperation of the first front wheel positioning device, the first rear wheel positioning device and the first guide device, the electric vehicle can drive into the battery exchange position along the preset path, and the first side front wheel and the first side rear wheel can be positioned more reliably.

[0040] Preferably, the first front wheel alignment device comprises:

[0041] A front positioning assembly and a rear positioning assembly disposed opposite to each other; and

[0042] a left positioning assembly and / or a right positioning assembly;

[0043] The front positioning assembly is used to limit the forward movement of the first side front wheel, and the rear positioning assembly is used to limit the backward movement of the first side front wheel. After the electric vehicle passes the rear positioning assembly, it is limited between the front positioning assembly and the rear positioning assembly.

[0044] The left positioning assembly is at least used to limit the leftward movement trend of the first-side front wheel, and the right positioning assembly is at least used to limit the rightward movement trend of the first-side front wheel.

[0045] In this solution, the front and rear locating assemblies are essential for front wheel alignment. They constrain the first-side front wheel between them. At least one of the left and right locating assemblies is present, and by coordinating the left and / or right locating assemblies with the front and rear locating assemblies, the first-side front wheel can be reliably positioned.

[0046] Preferably, the vehicle carrying platform further comprises a second guiding device, which is provided on the platform body along the second side of the platform body and is used to guide the wheels on the second side of the electric vehicle so that the electric vehicle can drive along a preset path into the battery replacement position;

[0047] The second guiding device is arranged opposite to the first guiding device, and the second guiding device includes a second guiding component, and the second guiding component is inclined in a direction away from the second side wheel.

[0048] In this solution, the first guide device primarily guides the first wheel, while the second guide device provides additional guidance for the second wheel. Compared to the first guide device, the guiding effectiveness of the second guide device is less demanding, so only one second guide assembly is provided. With the cooperation of the first and second guide devices, the first and second wheels of an electric vehicle can be reliably guided to their next position. As previously mentioned, the structural characteristics of the second guide assembly facilitate guiding the second wheels of different electric vehicle models and improve the reliability of guidance and positioning.

[0049] Preferably, the second guide assembly includes a second guide roller, and the second guide roller is configured to be axially rotatable so that the second side wheel can be restricted when driving in.

[0050] Preferably, the vehicle carrying platform further comprises a second rear wheel positioning device for positioning the second side rear wheel of the electric vehicle, and the second guide device and the second rear wheel positioning device are arranged in sequence along the direction of the preset path;

[0051] The second rear wheel alignment device includes a second rear wheel alignment component provided on one side of the parking place of the second rear wheel, and the extension direction of the second rear wheel alignment component is parallel to the direction of the preset path.

[0052] In this solution, the first rear wheel alignment device primarily positions the first rear wheel, while the second rear wheel alignment device supplements the second rear wheel. Compared to the first rear wheel alignment device, the second rear wheel alignment device places lower demands on the second rear wheel alignment device. Therefore, the second rear wheel alignment assembly is only provided on one side of the resting area of ​​the second rear wheel. Furthermore, the second rear wheel alignment assembly extends parallel to the direction of the predetermined path, facilitating alignment of the second rear wheel and thereby ensuring reliable positioning of the second rear wheel.

[0053] Preferably, the second rear wheel alignment assembly includes a second rear wheel alignment roller, and the second rear wheel alignment roller is configured to be axially rotatable so that the second side rear wheel can be restricted when driving in.

[0054] In this embodiment, when the second rear wheel enters the second rear wheel alignment assembly, the second rear wheel alignment roller can rotate axially, and the second rear wheel alignment roller interacts with the side surface of the second rear wheel, thereby causing the second rear wheel to be displaced, thereby positioning the second rear wheel to a desired position. The use of the second rear wheel alignment roller can more conveniently and reliably achieve the positioning of the second rear wheel. If the position of the second rear wheel deviates from the desired position, the second rear wheel can be more conveniently and reliably corrected under the action of the second rear wheel alignment roller.

[0055] Preferably, the second guide roller comprises a third guide roller portion and a fourth guide roller portion sequentially connected along the direction of the preset path, and the cross-sectional size of the third guide roller portion gradually increases along the direction of the preset path;

[0056] The second rear wheel alignment roller includes a third rear wheel alignment roller portion and a fourth rear wheel alignment roller portion sequentially connected along the direction of the preset path, and the cross-sectional size of the third rear wheel alignment roller portion gradually increases along the direction of the preset path.

[0057] In this embodiment, the structural characteristics of the third guide roller section and the third rear wheel positioning roller section enable them to also serve as guides. Specifically, the third guide roller section facilitates the second-side wheel to be guided from the third guide roller section to the fourth guide roller section. The third rear wheel positioning roller section further guides the second-side wheel after it has departed from the second guide device, thereby improving the reliability and efficiency of positioning the wheel on one side of the electric vehicle.

[0058] Preferably, the third guide roller portion and the third rear wheel positioning roller portion are tapered rollers, and the fourth guide roller portion and the fourth rear wheel positioning roller portion are cylindrical rollers.

[0059] In this solution, on the one hand, the conical roller can play the above-mentioned guiding role, and the cylindrical roller can guide or straighten the second side wheel; on the other hand, the outer surfaces of the conical roller and the cylindrical roller are curved surfaces with basically no sharp edges, which are not easy to cause damage to the second side wheel, which is beneficial to protecting the second side wheel.

[0060] Preferably, along the direction of the preset path, the second guiding device, the second rear wheel positioning device and the second front wheel positioning device are arranged in sequence.

[0061] In this solution, under the joint action of the second side front wheel positioning device, the second rear wheel positioning device and the second guide device, the second side wheel can be guided to the battery exchange position more reliably, and the second side wheel can be positioned more reliably.

[0062] Preferably, the first rear wheel alignment device further comprises a first rear wheel mounting plate, the first rear wheel alignment assembly is provided on the first rear wheel mounting plate, and the first rear wheel alignment assembly is mounted to the platform body via the first rear wheel mounting plate;

[0063] The first front wheel positioning device further includes a first front wheel mounting plate, and the front positioning assembly, the rear positioning assembly, the left positioning assembly, and the right positioning assembly are arranged on the first front wheel mounting plate and mounted to the platform body through the first front wheel mounting plate;

[0064] The second rear wheel alignment device further includes a second rear wheel mounting plate, the second rear wheel alignment assembly is provided on the second rear wheel mounting plate, and the second rear wheel alignment assembly is mounted to the platform body via the second rear wheel mounting plate;

[0065] The second front wheel alignment device further includes a front wheel alignment assembly and a second front wheel mounting plate. The front wheel alignment assembly is arranged on the second front wheel mounting plate and is mounted to the platform body through the second front wheel mounting plate.

[0066] In this solution, by acting on each of the above-mentioned mounting plates, the corresponding positioning assembly or positioning device can be operated more conveniently. For example, by adjusting the position of one of the above-mentioned mounting plates, the position of the corresponding positioning assembly or positioning device can be adjusted more conveniently.

[0067] Preferably, a plurality of first mounting holes are provided on the first rear wheel mounting plate, the first front wheel mounting plate, the second rear wheel mounting plate and the second front wheel mounting plate, a plurality of second mounting holes are provided on the platform body, and the first mounting plate is connected to the platform body through a plurality of first mounting holes, a plurality of second mounting holes and a plurality of first fasteners.

[0068] In this solution, each of the above-mentioned mounting plates is detachably connected to the platform body, which facilitates adjustment of the relative position of the mounting plates on the platform body and replacement or maintenance of the corresponding positioning components or structures in the positioning device.

[0069] Preferably, the first mounting hole is a waist-shaped hole, and the second mounting hole is a round hole; or, the first mounting hole is a round hole, and the second mounting hole is a waist-shaped hole.

[0070] In this solution, by adjusting the relative position of the second mounting hole and the first mounting hole, the relative position of the corresponding mounting plate and the platform body can be adjusted more conveniently, so that the position of the corresponding positioning component or positioning device relative to the platform body can be adjusted, so that the vehicle-carrying platform can be suitable for the positioning and battery replacement needs of different models of electric vehicles.

[0071] Preferably, the vehicle carrying platform also includes at least one moving component, and at least one of the moving components is used to enable the first rear wheel mounting plate and / or the first front wheel mounting plate and / or the second rear wheel mounting plate and / or the second front wheel mounting plate to move in a direction parallel to the preset path and / or perpendicular to the preset path.

[0072] In this solution, by operating the moving parts (through manual drive operation or automatic drive operation), under the action of the moving parts, the relative position of the corresponding mounting plate and the platform body can be adjusted, and the position of the corresponding positioning components and positioning devices on the platform body can be adjusted more conveniently, so that the vehicle-carrying platform can be suitable for the positioning and battery replacement needs of different models of electric vehicles.

[0073] Preferably, the left positioning assembly and the right positioning assembly each include at least two clamping rollers distributed up and down, and from bottom to top, at least two of the clamping rollers extend outward in sequence.

[0074] In this solution, the above-mentioned structural arrangement is adopted, and the clamping rollers extend outward in sequence to conveniently and reliably achieve positioning and clamping of the first front wheel.

[0075] Preferably, when the first front wheel is constrained between the front positioning assembly and the rear positioning assembly, from bottom to top, the two clamping rollers of the left positioning assembly and the right positioning assembly are respectively tangent to the outer side surfaces of the corresponding first front wheel.

[0076] In this solution, the clamping roller is tangent to the side of the first front wheel, has good fit with the first front wheel, and can apply sufficient clamping force to the first front wheel, thereby reliably positioning the first front wheel.

[0077] Preferably, the vehicle carrying platform further comprises a first lifting device and a second lifting device provided on the platform body, the first rear wheel positioning device and the second rear wheel positioning device are provided on the lifting platform of the first lifting device, and the first front wheel positioning device and the second front wheel positioning device are provided on the lifting platform of the second lifting device;

[0078] At least one of the moving components acts on the first rear wheel mounting plate, the second rear wheel mounting plate, the first front wheel mounting plate and the second front wheel mounting plate respectively;

[0079] The first lifting device is used to lift and lower the first rear wheel alignment device and the second rear wheel alignment device;

[0080] The second lifting device is used to lift and lower the first front wheel alignment device and the second front wheel alignment device.

[0081] In this solution, the first lifting device and the second lifting device can lift or lower the electric vehicle to cooperate with the battery swapping equipment to perform battery swapping operations on the electric vehicle. Accordingly, the battery swapping station including the above-mentioned vehicle loading platform does not need to dig a tunnel for the battery swapping equipment.

[0082] Preferably, the first guide device further comprises a first floor roller assembly, the first floor roller assembly being located between the two first guide assemblies and at a position where the first side wheel is parked, and the axis direction of the floor rollers in the first floor roller assembly is parallel to the direction of the preset path;

[0083] The second guide device further includes a second ground roller assembly, the second ground roller assembly being located on one side of the second guide assembly and at a position where the second side wheel is parked, and the axis direction of the ground roller in the second ground roller assembly is parallel to the direction of the preset path;

[0088] In this solution, the rolling friction between the ground roller assembly and the first side wheel (including the first side rear wheel and the first side front wheel) or the second side wheel (including the second side rear wheel and the second side front wheel) facilitates the more convenient and reliable alignment of the first side wheel and the second side wheel, thereby facilitating the convenient and reliable guidance and positioning of the first side wheel and the second side wheel.

[0089] Preferably, when at least a portion of the first side wheel is located between the two first guide assemblies, the highest point of the first guide assembly is not higher than the lowest point of the hub of the first side wheel.

[0090] In this solution, the above-mentioned structural setting is adopted so that it is the tire part of the first side wheel, rather than the hub part, that contacts and interacts with the first guide assembly in the first side wheel, which is conducive to ensuring the reliability of positioning and avoiding wear on the hub due to rigid contact.

[0091] The present invention also provides a battery swap station, which is characterized in that it includes the above-mentioned vehicle carrying platform.

[0172] A preferred embodiment is given below and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0173] Example 1

[0174] like Figure 1-2 As shown, this embodiment provides a battery swap station 100, which includes battery swap equipment and a vehicle loading platform 200, wherein the battery swap equipment is used to replace batteries in electric vehicles. The vehicle loading platform 200 includes a platform body 10 and a first guide device 20. The first guide device 20 is provided on the platform body 10 along a first side of the platform body 10 and is used to guide the wheels on the first side of the electric vehicle to drive the electric vehicle along a preset path to a battery swap position. The first guide device 20 includes two first guide assemblies arranged opposite to each other, and both first guide assemblies are inclined in a direction away from the wheels on the first side. In the direction of the preset path, the distance between the two first guide assemblies gradually decreases.

[0175] In this embodiment, the platform body 10 is used to carry an electric vehicle, and the first guide device 20 can guide the first side wheel of the electric vehicle, which is conducive to ensuring that the electric vehicle enters the battery swap position along the preset path. Among them, the first guide component is inclined in the direction away from the first side wheel, that is, the distribution of the two first guide components is in an "outward eight" shape. With this arrangement, on the one hand, at the end close to the entrance of the electric vehicle, the distance between the two first guide components is large, which is conducive to electric vehicles of different models (such as wheelbase) entering the first guide device 20 more conveniently; on the other hand, at the end away from the entrance of the electric vehicle, the distance between the two first guide components is small, which is conducive to improving the guiding effect of the first side wheel of the electric vehicle, so as to truly play a guiding role, which is conducive to improving the positioning reliability of the electric vehicle, and further conducive to enabling the electric vehicle to enter the battery swap position along the preset path.

[0176] like Figure 2-3 As shown, the first guide assembly includes a first guide roller 201 , and the first guide roller 201 is configured to be axially rotatable so that the first side wheel can be constrained between the two first guide rollers 201 when driving in.

[0177] In this embodiment, when the first-side wheel enters between the two first guide assemblies, the first guide roller 201 can rotate axially. The first guide roller 201 interacts with the first-side wheel, thereby causing the first-side wheel to move and guide it to a suitable position. The use of the first guide roller 201 can more conveniently and reliably guide the first-side wheel.

[0178] like Figure 2-3 As shown, the first guide roller 201 includes a first guide roller portion 202 and a second guide roller portion 203, which are sequentially connected along a predetermined path. The cross-sectional dimensions of the first guide roller portion 201 gradually increase along the predetermined path. The structural characteristics of the first guide roller portion 202 enable it to also serve as a guide. The first guide roller portion 202 facilitates the guidance of the first-side wheel from the first guide roller portion 202 to the second guide roller portion 203, thereby improving the reliability and efficiency of positioning the wheel on one side of the electric vehicle.

[0179] Specifically, in this embodiment, the first guide roller portion 202 and the first rear wheel alignment roller portion 302 are tapered rollers, while the second guide roller portion 203 and the second rear wheel alignment roller portion 303 are cylindrical rollers. On the one hand, the tapered rollers can perform the aforementioned guiding function, while the cylindrical rollers can guide or align the first-side wheel. On the other hand, the outer surfaces of the tapered and cylindrical rollers are curved and have essentially no sharp edges, which makes them less likely to damage the first-side wheel and helps protect it.

[0180] like Figure 1-3 As shown, the vehicle loading platform 200 also includes a first rear wheel alignment device 30 for aligning the first rear wheel of the electric vehicle. The first guide device 20 and the first rear wheel alignment device 30 are sequentially arranged along the direction of the preset path. The first rear wheel alignment device 30 includes a first rear wheel alignment assembly arranged on one side of the parking area of ​​the first rear wheel, and the extension direction of the first rear wheel alignment assembly is parallel to the direction of the preset path.

[0181] In this embodiment, the first rear wheel alignment device 30 includes two first rear wheel alignment assemblies arranged on both sides of the first side rear wheel parking position, and the two first rear wheel alignment assemblies position the first side rear wheel in the left and right directions perpendicular to the direction of the preset path.

[0182] In an alternative embodiment, the first-side rear wheel is guided to the first rear wheel alignment device 30 by the first guide device 20 , and under the action of the first rear wheel alignment assembly, the first-side rear wheel can be positioned in the first rear wheel alignment device 30 .

[0183] Among them, the first side rear wheel is guided to the first rear wheel positioning device 30 through the first guide device 20. Under the action of the relatively arranged first rear wheel positioning assembly, the two sides of the first side rear wheel are positioned respectively, so that the first side rear wheel can be positioned in the first rear wheel positioning device 30 more reliably.

[0184] Along the direction of the preset path, the distance between the first rear wheel locating device 30 and the first guiding device 20 is greater than or equal to 0 and is smaller than the diameter of the first side rear wheel.

[0185] In this embodiment, the first rear wheel alignment device 30 can be in direct contact with the first guide device 20, i.e., the distance between the first rear wheel alignment device 30 and the first guide device 20 is equal to zero, or a gap greater than zero and less than the diameter of the first rear wheel is formed between the first rear wheel alignment device 30 and the first guide device 20. When the distance is zero, a first-side wheel of the electric vehicle that has left a portion of the first guide device 20 can directly enter the first rear wheel alignment device 30, making it less likely for the first-side wheel to deviate again, thereby facilitating more reliable positioning of the first-side wheel. When the distance is greater than zero, it should be less than the diameter of the first rear wheel. This is because if the distance is too large (e.g., greater than the diameter of the first rear wheel), a wheel on the first side of the electric vehicle may not be in contact with the first rear wheel alignment device 30 after leaving the first guide device 20. In this case, the wheel may deviate, affecting the reliability of the wheel positioning. Here, by adopting the above arrangement, when the first side wheel leaves the first guide device 20, at least a portion of the first side wheel has contacted the first rear wheel positioning device 30, which facilitates the positioning of the first side wheel and helps to improve the reliability of the first side wheel positioning.

[0186] In a preferred embodiment, the distance between the first rear wheel alignment device 30 and the first guiding device 20 is greater than or equal to 0, and less than or equal to the radius of the first side rear wheel.

[0187] It should be noted that it is more preferred that the distance between the first rear wheel alignment device 30 and the first guide device 20 is 0. Figure 1 It is understood that the first guide device 20 is located on the ramp outside the box (such as a box assembled from containers), and the first rear wheel positioning device 30 is located inside the box. Therefore, the distance between the first rear wheel positioning device 30 and the first guide device 20 is at least the box wall of the box.

[0188] Continue reading Figure 1-3It is understood that the first rear wheel alignment assembly includes first rear wheel alignment rollers 301, which are configured to rotate axially so that the first-side rear wheel can be constrained between the two first rear wheel alignment rollers 301 when entering. When the first-side rear wheel enters the first rear wheel alignment assembly, the two first rear wheel alignment rollers 301 can rotate axially. The two first rear wheel alignment rollers 301 interact with both sides of the first-side rear wheel, thereby causing the first-side rear wheel to be displaced to position the first-side rear wheel to a desired position. The use of the first rear wheel alignment rollers 301 can more conveniently and reliably achieve the positioning of the first-side rear wheel. If the position of the first-side rear wheel deviates from the desired position, the first rear wheel can be more conveniently and reliably corrected under the action of the first rear wheel alignment rollers 301.

[0189] In addition, if Figure 3 As shown, the first rear wheel alignment roller 301 includes a first rear wheel alignment roller portion 302 and a second rear wheel alignment roller portion 303 sequentially connected along a preset path, and the cross-sectional size of the first rear wheel alignment roller portion 302 gradually increases along the preset path.

[0190] The structural characteristics of the first rear wheel alignment roller portion 302 enable it to also serve as a guide. The first rear wheel alignment roller portion 302 further guides the first side wheel that has departed from the first guide device 20, thereby facilitating improved reliability and efficiency in positioning the wheel on one side of the electric vehicle.

[0191] Further, if Figure 2-3 As shown, the first guide roller portion 202 and the first rear wheel alignment roller portion 302 are tapered rollers, while the second guide roller portion 203 and the second rear wheel alignment roller portion 303 are cylindrical rollers. On the one hand, the tapered rollers can perform the aforementioned guiding function, while the cylindrical rollers can guide or align the first-side wheel. On the other hand, the outer surfaces of the tapered and cylindrical rollers are curved and have essentially no sharp edges, which makes them less likely to damage the first-side wheel and helps protect it.

[0192] In an alternative embodiment, the distance between the two first rear wheel alignment assemblies is greater than the width of the first side rear wheel. A gap greater than zero is left between the two first rear wheel alignment assemblies and the first side rear wheel. In this configuration, when the electric vehicle needs to move, the gap ensures that the first rear wheel alignment assemblies do not hinder the movement of the first side rear wheel.

[0193] It should be noted that, in a preferred embodiment, the sum of the distances between the two first rear wheel alignment assemblies and the corresponding outer side surface of the first-side rear wheel is between 2-3 mm. In a more preferred embodiment, the distance between each first rear wheel alignment assembly and the corresponding outer side surface of the first-side rear wheel is between 1-1.5 mm.

[0194] like Figure 2 、 Figure 4-5 It is understood that the vehicle loading platform 200 also includes a first front wheel positioning device 40 for positioning the first side front wheel of the electric vehicle. Along the direction of the preset path, the first guide device 20, the first rear wheel positioning device 30, and the first front wheel positioning device 40 are arranged in sequence. Among them, through the cooperation of the first front wheel positioning device 40, the first rear wheel positioning device 30, and the first guide device 20, the electric vehicle can be driven into the battery swapping position along the preset path, and the first side front wheel and the first side rear wheel can be positioned relatively reliably.

[0195] Specifically, the first front wheel alignment device 40 includes: a front alignment assembly 401 and a rear alignment assembly 402 that are arranged opposite to each other; and a left alignment assembly 403 and / or a right alignment assembly 404. The front alignment assembly 401 is used to limit the forward movement of the first-side front wheel, and the rear alignment assembly 402 is used to limit the backward movement of the first-side front wheel. After the electric vehicle passes the rear alignment assembly 402, it is trapped between the front alignment assembly 401 and the rear alignment assembly 402. The left alignment assembly 403 is used to at least limit the leftward movement of the first-side front wheel, and the right alignment assembly 404 is used to at least limit the rightward movement of the first-side front wheel.

[0196] The front locating assembly 401 and the rear locating assembly 402 are essential for front wheel alignment. Under the action of the front locating assembly 401 and the rear locating assembly 402, the front wheel on the first side is constrained between the front locating assembly 401 and the rear locating assembly 402. At least one of the left locating assembly 403 and the right locating assembly 404 is present. By coordinating the left locating assembly 403 and / or the right locating assembly 404 with the front locating assembly 401 and the rear locating assembly 402, the front wheel on the first side can be positioned more reliably.

[0197] It should be noted that, in this embodiment, the first front wheel alignment device 40 includes: a front alignment component 401 and a rear alignment component 402 that are arranged opposite to each other; and a left alignment component 403 and a right alignment component 404 .

[0198] The front positioning assembly 401 and the rear positioning assembly 402 limit the front and rear directions of the first front wheel to determine the position of the electric vehicle in the front and rear directions.

[0199] The front positioning assembly 401 preferably has an adjacent first slope 4011 and a second slope 4012, wherein the first slope 4011 and the second slope 4012 are both inclined relative to the platform body 10, and the second slope 4012 limits the wheel and prevents the wheel from passing over the front positioning assembly 401 to a certain extent. When the electric vehicle passes over the second slope 4012 under the action of sufficient driving force, the first slope 4011 guides the wheel.

[0200] The rear positioning assembly 402 preferably has an adjacent third slope 4021 and a fourth slope 4022, wherein the third slope 4021 and the fourth slope 4022 are both inclined relative to the horizontal plane, and the fourth slope 4022 limits the wheel, preventing the wheel from moving backward and passing the rear positioning assembly 402 to a certain extent; before positioning, the electric vehicle needs to drive into the third slope 4021 and then into the fourth slope 4022. The third slope 4021 and the fourth slope 4022 allow the electric vehicle to smoothly contact the rear positioning assembly 402 from the second working surface and eventually pass the rear positioning assembly 402 to reach a predetermined position.

[0201] The left positioning component 403 and the right positioning component 404 limit the left and right directions of the wheel to determine the left and right positions of the electric vehicle. The left positioning component and the right positioning component jointly constrain the left and right positions of the wheel.

[0202] The left positioning assembly 403 and the right positioning assembly 404 have the same structure. The structures of the two are described below using the left positioning assembly 403 as an example.

[0203] The left positioning assembly 403 includes a plurality of clamping rollers 4031 and a mounting frame 4032. Preferably, there are three clamping rollers 4031, each with its own rotational axis parallel to the front-to-back axis, to facilitate wheel position adjustment. The rotational axis of each clamping roller 4031 is arranged to gradually approach the wheel of the electric vehicle from top to bottom. Therefore, when a wheel deviates from a preset position and lands on the left positioning assembly 403, the clamping rollers 4031 on the left positioning assembly 403 generate rolling friction with the wheel, causing the wheel to slide along the clamping rollers 4031 to the preset position.

[0204] like Figure 2 and Figure 6 As shown, the vehicle loading platform 200 further includes a second guiding device 50, which is provided on the platform body 10 along the second side of the platform body 10 and is used to guide the wheels on the second side of the electric vehicle so that the electric vehicle can drive along a preset path to the battery replacement position;

[0205] The second guiding device 50 is disposed opposite to the first guiding device 20 , and the second guiding device 50 includes a second guiding component that is inclined in a direction away from the second side wheel.

[0206] The first guide assembly 20 primarily guides the first wheel, while the second guide assembly 50 provides additional guidance for the second wheel. Compared to the first guide assembly 20, the guiding performance requirements for the second guide assembly 50 are lower, so only one second guide assembly is provided. With the cooperation of the first and second guide assemblies 20, the first and second wheels of the electric vehicle can be reliably guided to their next positions. As previously mentioned, the structural characteristics of the second guide assembly facilitate guiding the second wheels of different models of electric vehicles and improve the reliability of guidance and positioning.

[0207] The second guide assembly includes a second guide roller 501 , which is configured to be axially rotatable so that the second side wheel can be restricted when driving in.

[0208] like Figure 2 and Figure 6 As shown, the vehicle loading platform 200 also includes a second rear wheel alignment device 60 for aligning the second rear wheel of the electric vehicle. The second guide device 50 and the second rear wheel alignment device 60 are sequentially arranged along the direction of the preset path. The second rear wheel alignment device 60 includes a second rear wheel alignment assembly arranged on one side of the parking area of ​​the second rear wheel, and the extension direction of the second rear wheel alignment assembly is parallel to the direction of the preset path.

[0209] The first rear wheel alignment device 30 primarily positions the first rear wheel, while the second rear wheel alignment device 60 provides additional positioning for the second rear wheel. Compared to the first rear wheel alignment device 30, the second rear wheel alignment device 60 has lower requirements. Therefore, the second rear wheel alignment assembly is only provided on one side of the resting area of ​​the second rear wheel. Furthermore, the extension direction of the second rear wheel alignment assembly is parallel to the direction of the preset path, which facilitates alignment of the second rear wheel and further ensures reliable positioning of the second rear wheel.

[0210] The second rear wheel alignment assembly includes a second rear wheel alignment roller 601 , which is configured to be axially rotatable so that the second side rear wheel can be positioned when driving in.

[0211] The second guide roller 501 includes a third guide roller portion 502 and a fourth guide roller portion 503, which are sequentially connected along a predetermined path. The cross-sectional dimensions of the third guide roller portion 502 gradually increase along the predetermined path. The second rear wheel alignment roller 601 includes a third rear wheel alignment roller portion 602 and a fourth rear wheel alignment roller portion 603, which are sequentially connected along the predetermined path. The cross-sectional dimensions of the third rear wheel alignment roller portion 602 gradually increase along the predetermined path.

[0212] The third guide roller portion 502 and the third rear wheel positioning roller portion 602 are tapered rollers, and the fourth guide roller portion 503 and the fourth rear wheel positioning roller portion 603 are cylindrical rollers.

[0213] The vehicle loading platform 200 also includes a second front wheel positioning device 70 for positioning the second side front wheel of the electric vehicle. Along the direction of the preset path, the second guide device 50, the second rear wheel positioning device 60 and the second front wheel positioning device 70 are arranged in sequence.

[0214] Along the driving direction of the electric vehicle, the second front wheel positioning device 70 includes a second front wheel positioning roller 701 and a third front wheel positioning roller 702 in sequence. The second front wheel positioning roller 701 is arranged relatively tilted, and the third front wheel positioning roller 702 is arranged in a direction parallel to the preset path. Along the driving direction of the electric vehicle, the second front wheel positioning roller 701 gradually approaches the third front wheel positioning roller.

[0215] Similar to the front, the second front wheel alignment roller 701 gradually approaches the three front wheel alignment rollers, which also include tapered rollers and cylindrical rollers.

[0216] In an alternative embodiment, the vehicle loading platform 200 further includes a plurality of moving components, each of which is used to drive the first rear wheel alignment assembly to move in a direction parallel to the preset path and / or a direction perpendicular to the preset path;

[0217] Or, used to drive the front positioning assembly 401 and the rear positioning assembly 402 to move in a direction parallel to the preset path and / or a direction perpendicular to the preset path;

[0218] Or, used to drive the left positioning assembly 403 and / or the right positioning assembly 404 to move in a direction parallel to the preset path and / or a direction perpendicular to the preset path;

[0219] or, for driving the second rear wheel alignment assembly to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path;

[0220] Or, it is used to determine that the second front wheel alignment device 70 moves in a direction parallel to the preset path and / or a direction perpendicular to the preset path.

[0221] Among them, the first rear wheel positioning component of the first rear wheel positioning device 30, the front positioning component 401 and the rear positioning component 402 of the first front wheel positioning device 40, the left positioning component 403 and / or the right positioning component 404 of the first front wheel positioning device 40, the second rear wheel positioning component and the second front wheel positioning device 70 of the second rear wheel positioning device 60 can be moved respectively under the action of the moving parts, so that the movement of the above-mentioned positioning components or positioning devices can be achieved by operating the moving parts according to actual needs, so that the vehicle-carrying platform 200 can be suitable for the positioning and battery replacement needs of electric vehicles of different models (such as different wheelbases and different wheel widths), which is beneficial to reducing the overall battery replacement cost.

[0222] Alternatively, the first rear wheel alignment device 30 further includes a first rear wheel mounting plate, the first rear wheel alignment assembly is provided on the first rear wheel mounting plate, and the first rear wheel alignment assembly is mounted to the platform body 10 via the first rear wheel mounting plate;

[0223] The first front wheel alignment device 40 further includes a first front wheel mounting plate, and a front alignment component 401, a rear alignment component 402, a left alignment component 403, and a right alignment component 404 are provided on the first front wheel mounting plate and are mounted to the platform body 10 through the first front wheel mounting plate;

[0224] The second rear wheel alignment device 60 further includes a second rear wheel mounting plate, the second rear wheel alignment assembly is provided on the second rear wheel mounting plate, and the second rear wheel alignment assembly is mounted to the platform body 10 through the second rear wheel mounting plate;

[0225] The second front wheel alignment device 70 further includes a front wheel alignment assembly and a second front wheel mounting plate. The front wheel alignment assembly is provided on the second front wheel mounting plate and is mounted to the platform body 10 via the second front wheel mounting plate.

[0226] Among them, by acting on the above-mentioned each mounting plate, the corresponding positioning assembly or positioning device can be operated more conveniently. For example, by adjusting the position of the above-mentioned one mounting plate, the position of the corresponding positioning assembly or positioning device can be adjusted more conveniently.

[0227] A plurality of first mounting holes are provided on the first rear wheel mounting plate, the first front wheel mounting plate, the second rear wheel mounting plate and the second front wheel mounting plate, a plurality of second mounting holes are provided on the platform body 10, and the first mounting plate is connected to the platform body 10 through a plurality of first mounting holes, a plurality of second mounting holes and a plurality of first fasteners.

[0228] The above-mentioned mounting plates are detachably connected to the platform body 10, which is convenient for adjusting the relative position of the mounting plates on the platform body 10 and for replacing or maintaining the corresponding positioning components or structures in the positioning device.

[0229] Alternatively, the first mounting hole is a waist-shaped hole, and the second mounting hole is a round hole; or, the first mounting hole is a round hole, and the second mounting hole is a waist-shaped hole.

[0230] Among them, by adjusting the relative position of the second mounting hole and the first mounting hole, the relative position of the corresponding mounting plate and the platform body 10 can be adjusted more conveniently, so that the position of the corresponding positioning component or positioning device relative to the platform body 10 can be adjusted, so that the vehicle-carrying platform 200 can be suitable for the positioning and battery replacement needs of different models of electric vehicles.

[0231] The number of the second mounting holes is not less than the number of the first mounting holes. In this way, the position of the corresponding positioning assembly or positioning device relative to the platform body 10 can be adjusted more reliably and in a wider adjustment range.

[0232] Alternatively, the vehicle loading platform 200 further includes at least one moving component, and the at least one moving component is used to enable the first rear wheel mounting plate and / or the first front wheel mounting plate and / or the second rear wheel mounting plate and / or the second front wheel mounting plate to move in a direction parallel to the preset path and / or perpendicular to the preset path.

[0233] Among them, by operating the moving parts (through manual drive operation or automatic drive operation), under the action of the moving parts, the relative position of the corresponding mounting plate and the platform body 10 can be adjusted, and the position of the corresponding positioning components and positioning devices on the platform body 10 can be adjusted more conveniently, so that the vehicle-carrying platform 200 can be suitable for the positioning and battery replacement needs of different models of electric vehicles.

[0234] Alternatively, the left positioning assembly 403 and the right positioning assembly 404 each include at least two clamping rollers distributed up and down, and from bottom to top, the at least two clamping rollers extend outward in sequence.

[0235] Wherein, by adopting the above-mentioned structural arrangement, the clamping rollers extend outward in sequence to conveniently and reliably realize the positioning and clamping of the first front wheel.

[0236] Alternatively, when the first front wheel is constrained between the front positioning assembly 401 and the rear positioning assembly 402, from bottom to top, the two clamping rollers of the left positioning assembly 403 and the right positioning assembly 404 are respectively tangent to the outer side surface of the corresponding first front wheel.

[0237] The clamping roller is tangent to the side surface of the first front wheel, has good fit with the first front wheel, and can apply sufficient clamping force to the first front wheel, thereby reliably positioning the first front wheel.

[0238] Alternatively, the vehicle loading platform 200 further includes a first lifting device and a second lifting device provided on the platform body 10, the first rear wheel alignment device 30 and the second rear wheel alignment device 60 are provided on the lifting platform of the first lifting device, and the first front wheel alignment device 40 and the second front wheel alignment device 70 are provided on the lifting platform of the second lifting device;

[0239] at least one moving component acting on the first rear wheel mounting plate, the second rear wheel mounting plate, the first front wheel mounting plate, and the second front wheel mounting plate, respectively;

[0240] The first lifting device is used to lift the first rear wheel alignment device 30 and the second rear wheel alignment device 60;

[0241] The second lifting device is used to lift the first front wheel alignment device 40 and the second front wheel alignment device 70 .

[0242] In this solution, the first lifting device and the second lifting device can lift or lower the electric vehicle to cooperate with the battery exchange equipment to perform battery exchange operations on the electric vehicle. Accordingly, the battery exchange station 100 including the above-mentioned vehicle loading platform 200 does not need to dig a tunnel for the battery exchange equipment.

[0243] Alternatively, as Figure 1-6 As shown, the first guide device 20 further includes a first floor roller assembly 204, which is located between the two first guide assemblies and at the position where the first side wheel is parked, and the axis direction of the floor roller in the first floor roller assembly 204 is parallel to the direction of the preset path;

[0244] The second guide device 50 further includes a second floor roller assembly 504 ( Figure 6 ), the second floor roller assembly 504 is located on one side of the second guide assembly and is located at the position where the second side wheel is parked, and the axis direction of the floor roller in the second floor roller assembly 504 is parallel to the direction of the preset path;

[0245] The first rear wheel alignment device 30 further includes a third floor roller assembly 304. The third floor roller assembly 304 is located between the two first rear alignment assemblies 402, or on one side of the first rear wheel alignment assembly, and is located at a position where the first side rear wheel is parked. The axis direction of the floor rollers in the third floor roller assembly is parallel to the direction of the preset path.

[0246] The second rear wheel alignment device 60 further includes a fourth floor roller assembly 604, which is located on one side of the second rear wheel alignment assembly and at a position where the second rear wheel is parked, and the axis direction of the floor rollers in the fourth floor roller assembly 604 is parallel to the direction of the preset path;

[0247] In an alternative embodiment, the first front wheel alignment device 40 further includes a fifth floor roller assembly (not shown in the figure and may not be provided in this embodiment). The fifth floor roller assembly is located between the left alignment assembly 403 and the right alignment assembly 404, or located on one side of the left alignment assembly 403 or the right alignment assembly 404, and is located at the position where the first-side front wheel is parked. The axis direction of the floor rollers in the fifth floor roller assembly is parallel to the direction of the preset path.

[0248] The second front wheel alignment device 70 further includes a sixth floor roller assembly 703, which is located on one side of the front wheel alignment assembly and at the position where the second side front wheel is parked, and the axis direction of the floor roller in the sixth floor roller assembly 703 is parallel to the direction of the preset path.

[0249] Among them, through the rolling friction between the ground rolling assembly and the first side wheel (including the first side rear wheel and the first side front wheel) or the second side wheel (including the second side rear wheel and the second side front wheel), the first side wheel and the second side wheel can be more conveniently and reliably aligned, thereby facilitating the convenient and reliable guidance and positioning of the first side wheel and the second side wheel.

[0250] It should be noted that when at least a portion of the first-side wheel is positioned between the two first guide assemblies, the highest point of the first guide assembly is no higher than the lowest point of the hub of the first-side wheel. This structural arrangement ensures that the tire portion of the first-side wheel, rather than the hub portion, contacts and interacts with the first guide assembly. This helps ensure reliable positioning and prevents wear on the hub due to rigid contact.

[0251] The lifting device includes a first lifting device and a second lifting device, each of which includes a lifting platform and lifting components. The front and rear wheels of the electric vehicle, as well as the first rear wheel positioning device 30, the first front wheel positioning device 40, the second rear wheel positioning device 60, and the second front wheel positioning device 70 are located on the lifting platforms of the first and second lifting devices. Under the action of the lifting components, the electric vehicle can be raised or lowered to cooperate with the battery swapping equipment to perform battery swapping operations on the electric vehicle. Accordingly, the battery swapping station 100 does not need to dig a tunnel for the battery swapping equipment. It should be noted that the lifting device lifts the front or rear of the electric vehicle.

[0252] In this embodiment, the structures of the first hand-lifting device and the second hand-lifting device are basically the same. The first hand-lifting device is taken as an example to illustrate the hand-lifting device. Figure 7-8 As shown, the first lifting device includes a lifting platform and a lifting component, the lifting component includes at least one lifting assembly and a driving component, wherein the lifting assembly is used to lift or lower the lifting platform, and the driving component is used to drive the lifting assembly to lift or lower the lifting assembly.

[0253] Specifically, the lower end of the lifting assembly is connected to the platform body 10, and the upper end is connected to the lifting platform. The upper end of the lifting assembly can generate a height displacement relative to its lower end, thereby driving the lifting platform to move up and down to achieve lifting and lowering.

[0254] The lifting components can use one lifting assembly to lift and lower the lifting platform, or they can use multiple lifting assemblies to lift and lower the lifting platform. Figure 7-8 The example of achieving lifting and lowering by two sets of lifting components is used for illustration, but this illustration should not be understood as limiting the scope of protection of the present invention.

[0255] exist Figure 8 In the process, the two lifting components are arranged relative to each other in order to distribute the force more reasonably and avoid the situation where the lifting platform has excessive local stress and thus has a short service life.

[0256] The driving member drives the lifting assembly to move the lifting platform, thereby achieving the effect of lifting or lowering the electric vehicle.

[0257] As can be seen from the above, in this embodiment, the driving function and the lifting function are realized by different components, thereby making the structure of the lifting component modular and facilitating assembly and maintenance.

[0258] Please continue reading Figure 7-8 In this embodiment, the lifting assembly includes an active lifting member and a driven lifting member that are cross-arranged, and the driving member controls the cross angle of the active lifting member and the driven lifting member to achieve the lifting and lowering of the lifting platform.

[0259] Specifically, both lifting components adopt a scissor structure, that is, the projections of the active lifting member and the driven lifting member in the front and rear directions intersect and form two sets of diagonals, wherein the driving member is used to control a set of diagonals in the left and right directions. When the platform body 10 is lifted, the two angles in the set of diagonals gradually increase. During the lowering process, the two angles in the set of diagonals gradually decrease until the first lifting device reaches the initial state.

[0260] Example 2

[0261] like Figure 9 and Figure 10As shown, this embodiment provides a battery swap station 100, which includes a battery swap device and a vehicle loading platform 10, wherein the battery swap device is used to replace batteries for electric vehicles, and the vehicle loading platform 10 includes a platform body 1, a wheel alignment device 2, and a lifting device 3. Electric vehicles can travel onto the platform body 1, and the wheel alignment device 2 is provided on the platform body 1 at a position corresponding to the parking position of the wheels of the electric vehicle, for aligning the wheels. Four wheel alignment devices 2 can be provided, that is, a wheel alignment device 2 is provided for each wheel of the electric vehicle, or only two wheel alignment devices 2 can be provided, and the two wheel alignment devices 2 correspond to the two wheels on the left side of the electric vehicle, or the two wheels on the right side of the electric vehicle.

[0262] The lifting device 3 is provided on the platform body 1 and includes a lifting platform 31 and a lifting mechanism 32. The corresponding plurality of wheel alignment devices 2 are provided on the lifting platform 31. The lifting mechanism 32 is used to drive the lifting platform 31 up and down, so that the lifting device 3 can achieve the lifting and lowering of the electric vehicle. When the battery is replaced, the lifting device 3 cooperates with the battery replacement equipment to lift or lower the electric vehicle, thereby cooperating with the battery replacement equipment to realize the battery replacement operation of the electric vehicle (i.e., removing and installing the battery).

[0263] A single lifting device 3 can be used to lift the entire electric vehicle, or multiple lifting devices 3 can be used to achieve lifting and lowering. The example of using two lifting devices 3 to achieve lifting and lowering is used for illustration, but this illustration should not be understood as limiting the scope of protection of the present invention.

[0264] The wheel alignment device 2 can move, specifically, can move along the direction of a preset path, or move along a direction perpendicular to the preset path, or can move in both directions.

[0265] The wheel positioning device 2 can realize the positioning of the wheels, so that the position of the electric vehicle during each battery replacement can be accurately determined, and the position range of the battery pack to be replaced is correspondingly determined, which is conducive to improving the automation of the battery replacement process. At the same time, since the wheel positioning device 2 is movable, when different electric vehicles need to be replaced, the position of the wheel positioning device 2 can be adjusted accordingly to adapt to electric vehicles with different wheelbases and wheelbases, so that the vehicle-carrying platform 10 can position various models of electric vehicles. Therefore, a single battery replacement station 100 can be adapted to various models of electric vehicles, has high flexibility, reduces the construction cost of the battery replacement station 100, and reduces the battery replacement cost overall.

[0266] For example, when the electric vehicle that needs battery replacement has a larger wheelbase, the wheel alignment device 2 can be moved along the direction of the preset path to increase the distance between the two wheel alignment devices 2 in the direction of the preset path. Vice versa.

[0267] For another example, when the electric vehicle that needs battery replacement has a larger wheelbase, the wheel alignment device 2 can be moved in a direction perpendicular to the preset path to increase the distance between the two wheel alignment devices 2 in the direction perpendicular to the preset path. Vice versa.

[0268] like Figures 11 to 13 As shown, the wheel alignment device 2 includes a positioning component 21, which is used to limit the movement of the wheel in the front-to-back direction and / or the left-to-right direction. Therefore, a single positioning component 21 can achieve the positioning of the wheel in at least the front-to-back direction or the left-to-right direction, or can achieve the complete positioning of the wheel on the horizontal plane. By providing multiple wheel alignment devices 2, the electric vehicle can be completely positioned on the horizontal plane.

[0269] like Figure 14 and Figure 15 As shown, the wheel alignment device 2 further includes a moving component 22, which is used to drive the positioning component 21. Driven by the moving component 22, the positioning component 21 can move as a whole to adapt to different wheel positions, thereby adapting to different models of electric vehicles.

[0270] The moving part 22 includes a mounting platform 221 and a power source 222. The mounting platform 221 is connected to the bottom of the positioning part 21. The power source 222 is used to drive the mounting platform 221 to move along the direction of the preset path and / or perpendicular to the preset path. The mounting platform 221 is relatively fixed to the positioning part 21, and the power source 222 drives the mounting platform 221 to drive the positioning part 21 to move. In the present embodiment, the power source 222 is an electric push rod, which is installed on the lifting platform 31. The telescopic end 2221 of the electric push rod is connected to the mounting platform 221. The lifting platform 31 is provided with a connecting port 311 so that the mounting platform 221 can be connected to the bottom of the positioning part 21. The movement of the telescopic end 2221 can drive the mounting platform 221 to move. In certain other embodiments, the mounting platform 221 can also be a two-dimensional slide, and the positioning part 21 can be driven to move in any direction on the plane through the moving part 22.

[0271] The power source 222 can also be a drive device such as a screw, a motor, or a hydraulic system, and can also achieve automatic movement and adjustment, thereby improving the battery replacement efficiency. In some embodiments, the power source 222 can also be manually driven, that is, the installation platform 221 can be manually driven to move.

[0272] The positioning component 21 defines a guide groove, and the platform body 1 includes a vertically protruding guide block, which is slidably mounted within the guide groove. The guide groove extends along a predetermined path or perpendicular to the predetermined path. The guide groove and the guide block act in concert to allow the positioning component 21 to move in the direction in which the guide groove extends. The direction in which the guide groove extends can be set as needed.

[0273] Specifically, in this embodiment, the guide block is a bolt 220 connected to the platform body 1, and the guide slot is a waist hole 210 provided in the positioning member 21. Using the bolt 220 as the guide block is relatively easy to implement and has a relatively simple structure. Furthermore, when the positioning member 21 is adjusted to the desired position, the bolt 220 can be used to secure the positioning member 21 to the platform body 1, thereby firmly locking the positioning member 21 and preventing it from being dislodged by the wheel, thereby facilitating wheel securement.

[0274] The positioning component 21 includes multiple positioning assemblies located on its sides and a moving assembly. When a wheel rides on the positioning component 21, the positioning assemblies are positioned on the sides of the wheel, thereby restricting its movement. At least one positioning assembly is capable of moving along a predetermined path or perpendicular to the predetermined path, and the moving assembly is used to drive the positioning assembly's movement. The positioning assembly can be adjusted based on the track width, wheelbase, and wheel shape and size, thus adapting to different models of electric vehicles and different wheel models.

[0275] The plurality of positioning components include a front stop block 211 and a rear stop block 212, and / or a left positioning component 213 and a right positioning component 214. The moving component is used to drive the front stop block 211 and / or the rear stop block 212 to move along a preset path, or to drive the left positioning component 213 and / or the right positioning component 214 to move in a direction perpendicular to the preset path. A single positioning component 21 can be provided with only the front stop block 211 and the rear stop block 212, or only the left positioning component 213 and the right positioning component 214, or all four positioning components mentioned above can be provided at the same time to meet different positioning requirements. Those skilled in the art can make adjustments based on actual conditions.

[0276] The front limit block 211 is at least used to limit the forward movement trend of the wheels of the electric vehicle, the rear limit block 212 is at least used to limit the backward movement trend of the wheels of the electric vehicle, the left positioning component 213 is at least used to limit the left movement trend of the wheels of the electric vehicle, and the right positioning component 214 is at least used to limit the right movement trend of the wheels of the electric vehicle.

[0277] By adjusting the position of the front limit block 211 or the rear limit block 212 to adapt to different wheelbases and different wheel sizes, by adjusting the position of the left positioning component 213 and the right positioning component 214 to adapt to different wheelbases and different wheel sizes, only one of the front limit block 211 and the rear limit block 212 can be movable, or both can be movable. Similarly, only one of the left positioning component 213 and the right positioning component 214 can be movable, or both can be movable.

[0278] When the positioning component 21 is provided with a front limit block 211 and a rear limit block 212, at least one of the front limit block 211 and the rear limit block 212 is provided with a first guide groove (not shown in the figure) extending in the direction of a preset path, and the platform body 1 includes a first guide block (not shown in the figure) protruding in the vertical direction, and the first guide block is slidingly fitted in the first guide groove. Under the joint action of the first guide groove and the first guide block, the front limit block 211 and the rear limit block 212 can move in the direction of the preset path.

[0279] Similarly, when the positioning component 21 is provided with a left positioning component 213 and a right positioning component 214, at least one of the left positioning component 213 and the right positioning component 214 is provided with a second guide groove (not shown in the figure) extending in a direction perpendicular to the preset path, and the platform body 1 includes a second guide block (not shown in the figure) protruding in the vertical direction, and the second guide block is slidingly fitted in the second guide groove. Under the joint action of the second guide groove and the second guide block, the left positioning component 213 and the right positioning component 214 can move in the direction of the preset path.

[0280] In certain embodiments, both the left and right positioning assemblies 213 and 214 include positioning rollers 23 extending along a predetermined path. These rollers are connected to the platform body 1 via positioning brackets 24. If a wheel deviates and runs onto these rollers, they roll, and the wheel slides to a predetermined position along with the rollers. The second guide groove can be provided on the positioning brackets 24.

[0281] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the 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, and such changes and modifications are intended to fall within the scope of the present invention.
