Description

[0001] This application is a divisional application of a patent application with an application date of September 03, 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 station and is stably positioned, the battery swap equipment of the 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 can usually only swap batteries for a single model of electric vehicles. If other models of electric vehicles are replaced, due to the different wheelbases and wheelbases of electric vehicles, existing battery swap stations are usually unable to reliably locate and fix the electric vehicles, and thus cannot reliably perform battery swap operations. Therefore, the existing technology requires that different models of electric vehicles be equipped with corresponding battery swap stations, which greatly increases the cost of battery swapping. In addition, when using existing battery swap stations to swap batteries for electric vehicles, the positioning reliability of 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 to 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, characterized in that it comprises:

[0008] Platform body;

[0009] A first guiding device is arranged on the platform body along the first side of the platform body, and is used for guiding the first side wheel of the electric vehicle to drive the electric vehicle into the battery replacement position along a preset path. The first guiding device includes two first guiding components arranged opposite to each other. When at least a part of the first side wheel is located between the two first guiding components, the highest point of the first guiding component is not higher than the lowest point of the hub of the first side wheel.

[0010] In this solution, the platform body is used to carry the electric vehicle, and the first guide device can guide the first side wheel of the electric vehicle, which is conducive to ensuring that the electric vehicle enters the battery replacement position according to the preset path. Among them, when at least a part of the first side wheel is located between the two first guide components, the highest point of the first guide component is not higher than the lowest point of the wheel hub of the first side wheel. This arrangement makes it possible for the tire part of the first side wheel to contact and interact with the first guide component, rather than the wheel hub part, which is conducive to ensuring the reliability of positioning and avoiding wear of the wheel hub due to rigid contact.

[0011] 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.

[0012] In this solution, when the first side wheel enters between the two first guide assemblies, the first guide roller can rotate axially, and the first guide roller interacts with the first side wheel, so that the first side wheel can be displaced to guide the first side wheel to a suitable position. Among them, the use of the first guide roller can more conveniently and reliably achieve the guiding effect on the first side wheel.

[0013] Preferably, the vehicle-carrying platform further comprises a first rear wheel positioning device for positioning a first side rear wheel of the electric vehicle, and along the direction of the preset path, the first guiding device and the first rear wheel positioning device are sequentially arranged;

[0014] The first rear wheel alignment device comprises a first rear wheel alignment component arranged at one side of the parking place of the first side rear wheel, and the extension direction of the first rear wheel alignment component is parallel to the direction of the preset path.

[0015] In this solution, the first side rear wheel is guided to the first rear wheel positioning device through the first guiding device, and under the action of the first rear wheel positioning assembly, the first side rear wheel can be positioned in the first rear wheel positioning device.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] In this solution, the first rear wheel alignment device can be in direct contact with the first guide device, that is, the distance between the first rear wheel alignment device and the first guide device is equal to 0, or the first rear wheel alignment device can form a gap greater than 0 and less than the diameter of the first side rear wheel with the first guide device. When the above distance is 0, the first side wheel of the electric vehicle that has left a part of the first guide device can directly enter the first rear wheel alignment device, and the first side wheel is not likely to deviate again, which is conducive to more reliable positioning of the first side wheel; when the above distance is greater than 0, the distance is smaller than the diameter of the first side rear wheel, because if the above distance is too large (for example, exceeding the diameter of the first side rear wheel), after one wheel of the first side wheel leaves the first guide device, the wheel has not yet contacted the first rear wheel alignment device, and at this time, the wheel is easy to deviate, affecting the reliability of positioning the wheel. Here, the above arrangement is adopted, so that when the first side wheel leaves the first guide device, at least a part of the first side wheel has contacted the first rear wheel alignment device, which is convenient for positioning the first side wheel and is conducive to improving the reliability of positioning the first side wheel.

[0020] Preferably, the first rear wheel alignment assembly comprises 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.

[0021] In this solution, when the first side rear wheel enters the first rear wheel alignment assembly, the two first rear wheel alignment rollers can rotate axially, and the two first rear wheel alignment rollers interact with the two sides of the first side rear wheel, so that the first side rear wheel can be displaced to position the first side rear wheel to a desired position. The first rear wheel alignment rollers can be used to more conveniently and reliably achieve the positioning of the first side rear wheel, and if the position of the first side rear wheel deviates from the desired position, the first side rear wheel can be more conveniently and reliably adjusted to the desired position under the action of the first rear wheel alignment rollers.

[0022] Preferably, the first guide roller comprises a first guide roller portion and a second guide roller portion which are 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;

[0023] The first rear wheel positioning roller comprises a first rear wheel positioning roller portion and a second rear wheel positioning roller portion which are sequentially connected along the direction of the preset path, and the cross-sectional size of the first rear wheel positioning roller portion gradually increases along the direction of the preset path.

[0024] In this solution, the structural characteristics of the first guide roller part and the first rear wheel positioning roller part enable them to also play a guiding role. Among them, the first guide roller part enables the first side wheel to be guided from the first guide roller part to the second guide roller part more conveniently, and the first rear wheel positioning roller part further guides the first side wheel that has left the first guide device, thereby facilitating the improvement of the positioning reliability and efficiency of the wheel on one side of the electric vehicle.

[0025] Preferably, the first guide roller portion and the first rear wheel positioning roller portion are conical rollers, and the second guide roller portion and the second rear wheel positioning roller portion are cylindrical rollers.

[0026] In this scheme, on the one hand, the conical roller can play the above-mentioned guiding role, and the cylindrical roller can play a guiding or straightening role for 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.

[0027] Preferably, the distance between the two first rear wheel alignment assemblies is greater than the width of the first side rear wheel.

[0028] 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.

[0029] Preferably, the vehicle carrying platform also includes a first front wheel positioning device for positioning the first side front wheel of the electric vehicle, and 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.

[0030] 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 enter the battery replacement position along a preset path, and the first side front wheel and the first side rear wheel can be positioned more reliably.

[0031] Preferably, the first front wheel alignment device comprises:

[0032] A front positioning assembly and a rear positioning assembly disposed opposite to each other; and

[0033] A left positioning component and / or a right positioning component;

[0034] The front positioning assembly is used to limit the forward movement trend of the front wheel on the first side, and the rear positioning assembly is used to limit the backward movement trend of the front wheel on the first side. After the electric vehicle passes over the rear positioning assembly, it is limited between the front positioning assembly and the rear positioning assembly.

[0035] 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.

[0036] In this solution, the front positioning assembly and the rear positioning assembly are indispensable for front wheel positioning, and under the action of the front positioning assembly and the rear positioning assembly, the first side front wheel is limited between the front positioning assembly and the rear positioning assembly. There is at least one left positioning assembly and the right positioning assembly, and the left positioning assembly and / or the right positioning assembly are matched with the front positioning assembly and the rear positioning assembly to more reliably position the first side front wheel.

[0037] Preferably, both of the first guide assemblies are inclined in a direction away from the first side wheel;

[0038] Wherein, along the direction of the preset path, the distance between the two first guide components gradually decreases;

[0039] And / or, the vehicle-carrying platform further comprises a second guiding device, which is arranged 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 drives into the battery replacement position along a preset path;

[0040] 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.

[0041] In this solution, the first guide assembly is inclined in the direction away from the first side wheel, that is, the two first guide assemblies are distributed in an "outward eight" shape. In this way, on the one hand, at the end close to the entrance of the electric vehicle, the distance between the two first guide assemblies is large, which is conducive to electric vehicles of different models (such as wheelbase) entering the first guide device more conveniently; on the other hand, at the end away from the entrance of the electric vehicle, the distance between the two first guide assemblies 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, and is conducive to improving the positioning reliability of the electric vehicle, and further conducive to realizing the electric vehicle entering the battery replacement position along the preset path. The first guide device plays a main guiding role for the first side wheel, and the second guide device plays an additional guiding role for the second side wheel. Compared with the first guide device, the guiding effect of the second guide device is less required, so only one second guide assembly is set here. With the cooperation of the first guide device and the second guide device, the first side wheel and the second side wheel of the electric vehicle can be more reliably guided to the next position. As mentioned above, the structural characteristics of the second guide assembly are conducive to guiding the second side wheels of electric vehicles of different models, and are conducive to improving the reliability of guidance and positioning.

[0042] Preferably, the second guide assembly comprises a second guide roller, and the second guide roller is configured to be axially rotatable so that the second side wheel can be limited when driving in.

[0043] 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 along the direction of the preset path, the second guide device and the second rear wheel positioning device are arranged in sequence;

[0044] The second rear wheel alignment device comprises a second rear wheel alignment component arranged at 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.

[0045] In this solution, the first rear wheel alignment device plays a major role in locating the first side rear wheel, and the second rear wheel alignment device plays an additional role in locating the second side rear wheel. Compared with the first rear wheel alignment device, the second rear wheel alignment device has lower requirements. Therefore, the second rear wheel alignment assembly is only provided on one side of the parking position of the second side rear wheel. In addition, the extension direction of the second rear wheel alignment assembly is provided to be parallel to the direction of the preset path, which is conducive to aligning the second side rear wheel, and further conducive to ensuring the reliability of the positioning of the second side rear wheel.

[0046] Preferably, the second rear wheel alignment assembly comprises 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 limited when driving in.

[0047] In this solution, when the second side 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 of the second side rear wheel, so that the second side rear wheel can be displaced to position the second side rear wheel to a desired position. The second rear wheel alignment roller can be used to conveniently and reliably achieve the positioning of the second side rear wheel, and if the position of the second side rear wheel deviates from the desired position, the second side rear wheel can be conveniently and reliably adjusted to the desired position under the action of the second rear wheel alignment roller.

[0048] Preferably, the second guide roller comprises a third guide roller portion and a fourth guide roller portion which are 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;

[0049] The second rear wheel positioning roller comprises a third rear wheel positioning roller portion and a fourth rear wheel positioning roller portion which are sequentially connected along the direction of the preset path, and the cross-sectional size of the third rear wheel positioning roller portion gradually increases along the direction of the preset path.

[0050] In this solution, the structural characteristics of the third guide roller part and the third rear wheel positioning roller part enable them to also play a guiding role. Among them, the third guide roller part enables the second side wheel to be guided from the third guide roller part to the fourth guide roller part more conveniently, and the third rear wheel positioning roller part further guides the second side wheel that has left the second guide device, thereby facilitating the improvement of the positioning reliability and efficiency of the wheel on one side of the electric vehicle.

[0051] Preferably, the third guide roller portion and the third rear wheel positioning roller portion are conical rollers, and the fourth guide roller portion and the fourth rear wheel positioning roller portion are cylindrical rollers.

[0052] In this scheme, on the one hand, the conical roller can play the above-mentioned guiding role, and the cylindrical roller can play a guiding or straightening role for 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.

[0053] Preferably, the vehicle carrying platform also includes a second front wheel positioning device for positioning the second side front wheel of the electric vehicle, and along the direction of the preset path, the second guide device, the second rear wheel positioning device and the second front wheel positioning device are arranged in sequence.

For example, by adjusting the position of one of the above-mentioned mounting plates, the position of the corresponding positioning components or positioning devices can be adjusted more conveniently.

[0169] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0170] Example 1

[0171] like Figure 1-2 As shown, this embodiment provides a battery swap station 100, which includes a battery swap device and a vehicle loading platform 200, wherein the battery swap device is used to replace batteries for electric vehicles, and the vehicle loading platform 200 includes a platform body 10 and a first guide device 20, wherein the first guide device 20 is arranged on the platform body 10 along the first side of the platform body 10, and is used to guide the first side wheel of the electric vehicle to drive the electric vehicle into the battery swap position along a preset path, and the first guide device 20 includes two first guide components arranged opposite to each other, and the two first guide components are inclined in a direction away from the first side wheel. Wherein, along the direction of the preset path, the distance between the two first guide components gradually decreases.

[0172] In this embodiment, the platform body 10 is used to carry the 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 replacement position according to 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. In this way, 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 then it is conducive to realizing that the electric vehicle enters the battery replacement position along the preset path.

[0173] 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.

[0174] In this solution, when the first side wheel enters between the two first guide assemblies, the first guide roller 201 can rotate axially, and the first guide roller 201 interacts with the first side wheel, so that the first side wheel can be displaced to guide the first side wheel to a suitable position. The first guide roller 201 can be used to guide the first side wheel more conveniently and reliably.

[0175] 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 the direction of the preset path, and the cross-sectional size of the first guide roller portion 201 gradually increases along the direction of the preset path. The structural characteristics of the first guide roller portion 202 enable it to also play a guiding role. Among them, the first guide roller portion 202 enables the first side wheel to be more conveniently guided from the first guide roller portion 202 to the second guide roller portion 203, thereby facilitating the improvement of the positioning reliability and positioning efficiency of the wheel on one side of the electric vehicle.

[0176] Specifically, in this embodiment, the first guide roller part 202 and the first rear wheel positioning roller part 302 are tapered rollers, and the second guide roller part 203 and the second rear wheel positioning roller part 303 are cylindrical rollers. On the one hand, the tapered roller can play the above-mentioned guiding role, and the cylindrical roller can play the role of guiding or aligning the wheel on the first side; on the other hand, the outer surfaces of the tapered roller and the cylindrical roller are curved surfaces, which are basically without sharp edges, and are not easy to damage the wheel on the first side, which is conducive to protecting the wheel on the first side.

[0177] like Figure 1-3 As shown, the vehicle loading platform 200 also includes a first rear wheel positioning device 30 for positioning the first side rear wheel of the electric vehicle, and the first guide device 20 and the first rear wheel positioning device 30 are sequentially arranged along the direction of the preset path. The first rear wheel positioning device 30 includes a first rear wheel positioning assembly arranged at one side of the parking place of the first side rear wheel, and the extension direction of the first rear wheel positioning assembly is parallel to the direction of the preset path.

[0178] In this embodiment, the first rear wheel alignment device 30 includes two first rear wheel alignment components relatively arranged on both sides of the parking position of the first side rear wheel, and the two first rear wheel alignment components position the first side rear wheel in the left and right direction perpendicular to the direction of the preset path.

[0179] 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 .

[0180] 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.

[0181] Along the direction of the preset path, the distance between the first rear wheel alignment 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.

[0182] In this embodiment, the first rear wheel alignment device 30 can be in direct contact with the first guide device 20, that is, the distance between the first rear wheel alignment device 30 and the first guide device 20 is equal to 0, or the first rear wheel alignment device 30 can form a gap greater than 0 and less than the diameter of the first side rear wheel with the first guide device 20. When the distance is 0, the first side wheel of the electric vehicle that has left a part of the first guide device 20 can directly enter the first rear wheel alignment device 30, and the first side wheel is not likely to deviate again, which is conducive to more reliable positioning of the first side wheel; when the distance is greater than 0, the distance is smaller than the diameter of the first side rear wheel, because if the distance is too large (for example, greater than the diameter of the first side rear wheel), after one wheel of the first side wheel leaves the first guide device 20, the wheel has not yet contacted the first rear wheel alignment device 30, and at this time, the wheel is likely to deviate, affecting the reliability of positioning the wheel. Here, the above arrangement is adopted so that when the first side wheel leaves the first guiding 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.

[0183] 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.

[0184] 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.

[0185] Continue reading Figure 1-3 It is understood that the first rear wheel alignment assembly includes a first rear wheel alignment roller 301, and the first rear wheel alignment roller 301 is configured to be axially rotatable, so that the first side rear wheel can be limited 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 be axially rotated, and the two first rear wheel alignment rollers 301 interact with both sides of the first side rear wheel, so that the first side rear wheel can be displaced to position the first side rear wheel to the desired position. Among them, the use of the first rear wheel alignment roller 301 can more conveniently and reliably achieve the positioning of the first side rear wheel, wherein, if the position of the first side rear wheel deviates from the desired position, under the action of the first rear wheel alignment roller 301, the position of the first side rear wheel can be more conveniently and reliably adjusted.

[0186] 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 which are 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.

[0187] The structural characteristics of the first rear wheel positioning roller part 302 enable it to also play a guiding role. The first rear wheel positioning roller part 302 further guides the first side wheel that leaves the first guiding device 20, thereby facilitating the improvement of the positioning reliability and efficiency of the wheel on one side of the electric vehicle.

[0188] Furthermore, if Figure 2-3 As shown, the first guide roller part 202 and the first rear wheel positioning roller part 302 are tapered rollers, and the second guide roller part 203 and the second rear wheel positioning roller part 303 are cylindrical rollers. On the one hand, the tapered roller can play the above-mentioned guiding role, and the cylindrical roller can play the role of guiding or aligning the wheel on the first side; on the other hand, the outer surfaces of the tapered roller and the cylindrical roller are curved surfaces, which basically have no sharp edges, and are not easy to cause damage to the wheel on the first side, which is conducive to protecting the wheel on the first side.

[0189] 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 0 is left between the two first rear wheel alignment assemblies and the first side rear wheel. In this way, when the electric vehicle needs to move, the gap ensures that the first rear wheel alignment assemblies will not hinder the movement of the first side rear wheel.

[0190] 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.

[0191] like Figure 2 , Figure 4-5 It is understood that the vehicle-carrying platform 200 also includes a first front wheel positioning device 40 for positioning the first side front wheel of the electric vehicle, and 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 sequentially arranged. 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 replacement position along the preset path, and the first side front wheel and the first side rear wheel can be positioned more reliably.

[0192] Specifically, 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 / or a right alignment component 404; wherein the front alignment component 401 is used to limit the forward movement trend of the front wheel on the first side, and the rear alignment component 402 is used to limit the backward movement trend of the front wheel on the first side, and the electric vehicle is limited between the front alignment component 401 and the rear alignment component 402 after passing the rear alignment component 402. The left alignment component 403 is at least used to limit the leftward movement trend of the front wheel on the first side, and the right alignment component 404 is at least used to limit the rightward movement trend of the front wheel on the first side.

[0193] Among them, the front positioning assembly 401 and the rear positioning assembly 402 are indispensable for front wheel positioning, and under the action of the front positioning assembly 401 and the rear positioning assembly 402, the first side front wheel is limited between the front positioning assembly 401 and the rear positioning assembly 402. There is at least one of the left positioning assembly 403 and the right positioning assembly 404, and the left positioning assembly 403 and / or the right positioning assembly 404 are matched with the front positioning assembly 401 and the rear positioning assembly 402, so that the first side front wheel can be positioned more reliably.

[0194] 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 .

[0195] 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.

[0196] The front positioning assembly 401 preferably has a first slope 4011 and a second slope 4012 adjacent to each other, 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 wheels, preventing the wheels 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 wheels.

[0197] The rear positioning component 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 wheels, preventing the wheels from moving backward and passing over the rear positioning component 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, and the third slope 4021 and the fourth slope 4022 enable the electric vehicle to smoothly contact the rear positioning component 402 from the second working surface and eventually pass over the rear positioning component 402 to reach a predetermined position.

[0198] The left positioning component 403 and the right positioning component 404 limit the left and right directions of the wheels to determine the left and right directions of the electric vehicle. The left positioning component and the right positioning component jointly restrict the left and right directions of the wheels.

[0199] 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.

[0200] The left positioning assembly 403 includes a plurality of clamping rollers 4031 and a mounting frame 4032. Preferably, there are three clamping rollers 4031, and the rotation axes of the clamping rollers 4031 are parallel and located in the front-rear direction, so as to adjust the orientation of the wheel; the rotation axes of the clamping rollers 4031 are arranged to gradually approach the wheel of the electric vehicle from top to bottom, so that when the position of the wheel deviates from the preset position and falls on the left positioning assembly 403, the clamping rollers 4031 on the left positioning assembly 403 will generate rolling friction with the wheel, so that the wheel slides along the clamping rollers 4031 to the preset position.

[0201] like Figure 2 and Figure 6 As shown, the vehicle loading platform 200 further includes a second guiding device 50, which is disposed 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 drives into the battery replacement position along a preset path;

[0202] 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, and the second guiding component is inclined in a direction away from the second side wheel.

[0203] The first guide device 20 plays a major guiding role for the first side wheel, and the second guide device 50 plays an additional guiding role for the second side wheel. Compared with the first guide device 20, the guiding effect of the second guide device 50 is less required, so only one second guide assembly is provided. With the cooperation of the first guide device 20 and the second guide device 50, the first side wheel and the second side wheel of the electric vehicle can be guided to the next position more reliably. As mentioned above, the structural characteristics of the second guide assembly are conducive to guiding the second side wheels of electric vehicles of different models, and are conducive to improving the reliability of guidance and positioning.

[0204] The second guide assembly includes a second guide roller 501, and the second guide roller 501 is configured to be axially rotatable so that the second side wheel can be limited when driving in.

[0205] like Figure 2 and Figure 6As shown, the vehicle loading platform 200 further includes a second rear wheel positioning device 60 for positioning the second side rear wheel of the electric vehicle, and the second guide device 50 and the second rear wheel positioning device 60 are sequentially arranged along the direction of the preset path. The second rear wheel positioning device 60 includes a second rear wheel positioning assembly arranged at one side of the parking place of the second side rear wheel, and the extension direction of the second rear wheel positioning assembly is parallel to the direction of the preset path.

[0206] The first rear wheel alignment device 30 plays a major role in locating the first side rear wheel, and the second rear wheel alignment device 60 plays an additional role in locating the second side rear wheel. Compared with 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 parking position of the second side rear wheel. In addition, the extension direction of the second rear wheel alignment assembly is provided to be parallel to the direction of the preset path, which is conducive to aligning the second side rear wheel, and further conducive to ensuring the reliability of the positioning of the second side rear wheel.

[0207] The second rear wheel alignment assembly comprises a second rear wheel alignment roller 601, and the second rear wheel alignment roller 601 is configured to be axially rotatable so that the second side rear wheel can be limited when driving in.

[0208] The second guide roller 501 includes a third guide roller portion 502 and a fourth guide roller portion 503 which are sequentially connected along the direction of the preset path, and the cross-sectional size of the third guide roller portion 502 gradually increases along the direction of the preset path. The second rear wheel positioning roller 601 includes a third rear wheel positioning roller portion 602 and a fourth rear wheel positioning roller portion 603 which are sequentially connected along the direction of the preset path, and the cross-sectional size of the third rear wheel positioning roller portion 602 gradually increases along the direction of the preset path.

[0209] 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.

[0210] 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 guiding device 50, the second rear wheel positioning device 60 and the second front wheel positioning device 70 are arranged in sequence.

[0211] 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, and along the driving direction of the electric vehicle, the second front wheel positioning roller 701 gradually approaches the third front wheel positioning roller.

[0212] Similar to the previous one, the second front wheel positioning roller 701 gradually approaches the three front wheel positioning rollers, which also include conical rollers and cylindrical rollers.

[0213] In an alternative embodiment, the vehicle loading platform 200 further includes a plurality of moving components, and the plurality of moving components are respectively used to drive the first rear wheel alignment assembly to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path;

[0215] Or, used to drive the left positioning component 403 and / or the right positioning component 404 to move in a direction parallel to the preset path and / or in a direction perpendicular to the preset path;

[0216] or, used to drive 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;

[0217] 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.

[0218] 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 carrier 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.

[0219] Alternatively, the first rear wheel alignment device 30 further includes a first rear wheel mounting plate, the first rear wheel alignment assembly is disposed 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;

[0220] The first front wheel positioning device 40 also includes a first front wheel mounting plate, and the front positioning component 401, the rear positioning component 402, the left positioning component 403, and the right positioning component 404 are arranged on the first front wheel mounting plate and are mounted to the platform body 10 through the first front wheel mounting plate;

[0221] The second rear wheel alignment device 60 further includes a second rear wheel mounting plate, the second rear wheel alignment assembly is disposed 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;

[0222] The second front wheel alignment device 70 further includes a front wheel alignment assembly and a second front wheel mounting plate.

[0225] 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.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] 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 a preset path and / or perpendicular to a preset path.

[0231] 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, at least two clamping rollers extend outward in sequence.

[0232] Among them, 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.

[0233] 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.

[0234] 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.

[0235] Alternatively, the vehicle loading platform 200 further comprises a first lifting device and a second lifting device disposed on the platform body 10, the first rear wheel positioning device 30 and the second rear wheel positioning device 60 are disposed on the lifting platform of the first lifting device, and the first front wheel positioning device 40 and the second front wheel positioning device 70 are disposed on the lifting platform of the second lifting device;

[0236] At least one moving component 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;

[0237] The first lifting device is used to lift the first rear wheel positioning device 30 and the second rear wheel positioning device 60;

[0238] The second lifting device is used to lift the first front wheel alignment device 40 and the second front wheel alignment device 70 .

[0239] 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 100 including the above-mentioned vehicle loading platform 200 does not need to dig a tunnel for the battery swapping equipment.

[0240] Alternatively, if Figure 1-6 As shown, the first guide device 20 further includes a first ground roller assembly 204, the first ground roller assembly 204 is located between the two first guide assemblies and at the position where the first side wheel stops, and the axis direction of the ground roller in the first ground roller assembly 204 is parallel to the direction of the preset path;

[0241] The second guide device 50 further includes a second floor rolling assembly 504 ( Figure 6), the second ground roller assembly 504 is located at one side of the second guide assembly and at the position where the second side wheel is parked, and the axis direction of the ground roller in the second ground roller assembly 504 is parallel to the direction of the preset path;

[0242] The first rear wheel alignment device 30 further includes a third floor rolling assembly 304, which is located between the two first rear alignment assemblies 402, or located on one side of the first rear wheel alignment assembly, and located at the position where the first side rear wheel is parked, and the axis direction of the floor rolling in the third floor rolling assembly is parallel to the direction of the preset path;

[0245] The second front wheel alignment device 70 also includes a sixth floor rolling 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 rolling assembly 703 is parallel to the direction of the preset path.

[0246] 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), it is convenient and reliable to align 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.

[0247] It should be noted that 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 wheel hub of the first side wheel. The above structure arrangement enables the tire portion of the first side wheel to contact and interact with the first guide assembly, rather than the wheel hub portion, which is conducive to ensuring the reliability of positioning and avoiding wear of the wheel hub due to rigid contact.

[0248] The lifting device includes a first lifting device and a second lifting device, both of which include a lifting platform and a lifting component. The front wheels, rear wheels, first rear wheel positioning device 30, first front wheel positioning device 40, second rear wheel positioning device 60 and second front wheel positioning device 70 of the electric vehicle are located on the lifting platforms of the first lifting device and the second lifting device. Under the action of the lifting component, the electric vehicle can be lifted or lowered to cooperate with the battery swapping device 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 device. It should be noted that the lifting device lifts the front or rear of the electric vehicle.

[0249] In this embodiment, the structures of the first hand-lifting device and the second hand-lifting device are substantially 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 member, wherein the lifting assembly is used to lift or lower the lifting platform, and the driving member is used to drive the lifting assembly to raise or lower the lifting assembly.

[0250] 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.

[0251] The lifting component can use one lifting assembly to lift and lower the lifting platform, or it can use multiple lifting assemblies to lift and lower the lifting platform. Figure 7-8 The example of lifting and lowering by two sets of lifting components is used for illustration, but this illustration should not be construed as limiting the scope of protection of the present invention.

[0252] exist Figure 8 In the process, the two lifting components are arranged relatively 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.

[0253] The driving member drives the lifting assembly to move so as to realize the lifting and lowering of the lifting platform, thereby achieving the effect of lifting or lowering the electric vehicle.

[0254] As can be seen from the above, in this embodiment, the driving function and the lifting function are realized by different components, so that the structure of the lifting component is modularized, which is convenient for assembly and maintenance.

[0255] 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.

[0256] 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-to-back direction intersect and form two sets of diagonals, wherein the driving member is used to control a set of diagonals in the left-right direction, and when the platform body 10 is lifted, the two angles in the set of diagonals gradually increase, and during the lowering process, the two angles in the set of diagonals gradually decrease until the first lifting device reaches the initial state.

[0257] Example 2

[0258] like Fig. 9 and Fig.10 As shown, this embodiment provides a battery swap station 100, which includes a battery swap device and a vehicle-carrying platform 10, wherein the battery swap device is used to replace batteries for electric vehicles, and the vehicle-carrying platform 10 includes a platform body 1, a wheel alignment device 2, and a lifting device 3. The electric vehicle can travel onto the platform body 1, and the wheel alignment device 2 is arranged on the platform body 1 at a position corresponding to the parking position of the wheels of the electric vehicle, and is used to align the wheels. Four wheel alignment devices 2 can be provided, that is, each wheel of the electric vehicle is provided with a wheel alignment device 2, 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 to the two wheels on the right side of the electric vehicle.

[0259] The lifting device 3 is arranged on the platform body 1, and the lifting device 3 includes a lifting platform 31 and a lifting mechanism 32, and the corresponding plurality of wheel alignment devices 2 are arranged on the lifting platform 31. The lifting mechanism 32 is used to drive the lifting platform 31 to move up and down, so the lifting device 3 can realize 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, so as to cooperate with the battery replacement equipment to realize the battery replacement operation of the electric vehicle (i.e., removing and installing the battery).

[0260] 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 lifting and lowering achieved by two lifting devices 3 is illustrated as an example, but this illustration should not be understood as limiting the scope of protection of the present invention.

[0261] The wheel alignment device 2 can move, specifically, can move along the direction of a preset path, or can move along a direction perpendicular to the preset path, or can move in both directions.

[0262] The wheel positioning device 2 can realize the positioning of the wheel, so as to accurately determine the position of the electric vehicle during each battery replacement, and correspondingly determine the position range of the battery pack to be replaced, which is beneficial to improve 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.

[0263] For example, when the electric vehicle that needs to be replaced 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. And vice versa.

[0264] For another example, when the electric vehicle that needs to be replaced 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. And vice versa.

[0265] like Figures 11 to 13 As shown, the wheel alignment device 2 includes a positioning component 21, and the positioning component 21 is used to limit the movement trend of the wheel in the front-to-back direction and / or the movement trend in the left-to-right direction. Therefore, a single positioning component 21 can realize the positioning of the wheel at least in the front-to-back direction or the left-to-right direction, or can realize the complete positioning of the wheel on the horizontal plane. By setting a plurality of wheel alignment devices 2, the complete positioning of the electric vehicle on the horizontal plane can be realized.

[0266] like Fig.14 and Fig.15 As shown, the wheel alignment device 2 further comprises a moving component 22, and the moving component 22 is used to drive the positioning component 21 to move. 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.

[0267] 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 this 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, and the movement of the telescopic end 2221 can drive the mounting platform 221 to move. In some 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.

[0268] The power source 222 can also be a drive device such as a screw rod, a motor, or a hydraulic system, and can also realize automatic movement and adjustment, thereby improving the efficiency of battery replacement. In some embodiments, the power source 222 can also be manually driven, that is, the installation platform 221 can be driven manually to move.

[0270] Specifically in this embodiment, the guide block is a bolt 220 connected to the platform body 1, and the guide groove is a waist hole 210 opened on the positioning component 21. It is easier to use the bolt 220 as a guide block, and the structure is relatively simple. Moreover, when the positioning component 21 is adjusted to a suitable position, the bolt 220 can be used to fix the positioning component 21 to the platform body 1, so that the positioning component 21 is firmly locked to prevent the wheel from pushing the positioning component 21 away, so as to facilitate the fixing of the wheel.

[0271] The positioning component 21 includes a plurality of positioning components located at the side and a moving component. When the wheel travels onto the positioning component 21, the positioning component is located at the side of the wheel to limit the movement of the wheel. At least one positioning component can move along the direction of a preset path or in a direction perpendicular to the preset path, and the moving component is used to drive the positioning component to move. The positioning component can adjust the position according to the wheelbase, wheelbase, and the shape and size of the wheel, so that it can be adapted to different models of electric vehicles and different models of wheels.

[0272] 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 in the direction of 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 may 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 the above four positioning components may be provided at the same time to meet different positioning requirements. Those skilled in the art may make adjustments according to actual conditions.

[0275] 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 slidably arranged 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.

[0276] 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 slidably arranged 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.

[0277] In some embodiments, both the left positioning assembly 213 and the right positioning assembly 214 include positioning rollers 23 extending in the direction of a preset path, and the positioning rollers 23 are connected to the platform body 1 through positioning brackets 24. If the wheel deviates and runs onto the positioning rollers 23, the positioning rollers 23 roll, and the wheel slides to the preset position along the rolling of the positioning rollers 23. The second guide groove can be provided on the positioning brackets 24.
