Description

[0001] This application is a division of a Chinese invention patent with an application date of September 30, 2020, application number 202011066101.0, and name “Positioning and Alignment Equipment, Battery Replacement Platform and Battery Replacement Station”. Technical Field

[0002] The invention relates to a positioning and straightening device, a battery replacement platform and a battery replacement station. Background Art

[0003] The battery swap station includes a battery swap room and a charging room. The battery swap room has a battery swap platform, the charging room has battery swap equipment, and there is a passage between the battery swap room and the charging room. The electric vehicle is docked on the battery swap platform. When taking or replacing the battery, the battery swap equipment drives along the passage from the charging room to the battery swap room, and takes or replaces the battery at the bottom of the electric vehicle.

[0004] In the prior art, in order to accurately position the electric vehicle, the battery replacement platform introduces a car straightener, which mainly adjusts the position of the electric vehicle to the correct position through the left and right push plates. However, since the car straightener uses more than two transmission devices to work on the left and right push plates respectively, the longitudinal axis of the electric vehicle is often inconsistent with the reference line, which is not conducive to obtaining a more accurate position. At the same time, different models of electric vehicles have different positioning positions on the battery replacement platform, so that the battery replacement platform cannot accurately position different models of electric vehicles through the car straightener, and there is even a phenomenon that the electric vehicle cannot enter the battery replacement platform, which is not universal, and thus causes high costs of the battery replacement station. The existing vehicle positioning device, such as the solution disclosed in the Chinese patent application with publication number CN208993660U and application number CN201821440018.3, includes a platform base, which is used to park the vehicle to be replaced; and at least one first adjustment device, when the vehicle to be replaced is parked on the vehicle replacement platform, the first adjustment device supports the wheels of the vehicle to be replaced; and is used to adjust the vehicle to be replaced in the horizontal direction and the vertical direction. The first adjustment device includes a V-shaped roller row and a push rod that reciprocates laterally, wherein the push rod pushes the wheel of the vehicle to be replaced supported on the V-shaped roller row to move laterally when force is applied, and moves back to the original position when no force is applied. The above scheme only discloses limiting along the width direction of the vehicle body, as well as the scheme disclosed in publication number CN111231756A and application number CN202010085452.X, which only discloses a limiting portion for positioning along the length direction of the vehicle body, but none of the above schemes discloses a scheme for simultaneous positioning along the width and length directions of the vehicle body, and cannot realize simultaneous positioning along the length and width directions of the vehicle body when replacing batteries for electric vehicles of various models, resulting in inaccurate positioning. Summary of the invention

[0067] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0068] like Figure 1 , Figure 2 and Figure 3 As shown, the battery replacement platform of the embodiment of the present invention includes a mounting platform and at least one positioning and alignment device 10. The positioning and alignment device 10 is arranged on the mounting platform and is located at the position where the front wheels and / or rear wheels of the electric vehicle are parked. The positioning and alignment device 10 is used to position the electric vehicle on the battery replacement platform for battery replacement.

[0069] The positioning and straightening device 10 is arranged on the installation platform, and the positioning and straightening device 10 includes a first positioning component 1, and the first positioning component 1 is used to position the electric vehicle along the width direction of the vehicle body. The first positioning component 1 includes a telescopic part 12 and a first driving part 11. The telescopic part 12 is used to abut against the wheel of the electric vehicle and position the electric vehicle in the width direction of the vehicle body; the first driving part 11 is used to drive the telescopic part 12 to extend and retract along the width direction of the vehicle body.

[0070] The positioning and alignment device 10 is installed on the installation platform. When the electric vehicle enters the battery replacement platform, the first driving part 11 will be used to drive the telescopic part 12 to move, so that the telescopic part 12 abuts against the wheels of the electric vehicle and pushes the electric vehicle to move along the width direction of the vehicle body, thereby realizing the precise positioning of the electric vehicle on the battery replacement platform, ensuring that the longitudinal axis of the electric vehicle is consistent with the reference line, thereby greatly improving the stability during the battery replacement process. At the same time, the first positioning component 1 can be used to position electric vehicles of different models along the width direction of the vehicle body, and accurate positioning can be achieved for electric vehicles of different models, greatly improving the versatility of the battery replacement platform and reducing costs.

[0071] In this embodiment, the positioning and alignment device 10 is arranged on the mounting platform and is located at the position where the front wheels of the electric vehicle are parked. The battery replacement platform also includes a rear wheel positioning and alignment device 20, which is the first positioning component 1 as described above. The rear wheel positioning and alignment device 20 also includes a telescopic part 12 and a first driving part 11. The telescopic part 12 is used to abut against the rear wheels of the electric vehicle and position the electric vehicle in the width direction of the vehicle body.

[0072] By arranging the positioning and alignment device 10 and the rear wheel positioning and alignment device 20 at the parking positions of the front and rear wheels of the electric vehicle, the front and rear wheels of the electric vehicle are positioned along the width direction of the vehicle body, further ensuring that the longitudinal axis of the electric vehicle is consistent with the reference line, greatly improving the stability during the battery replacement process. At the same time, accurate positioning can be achieved for electric vehicles of different models, greatly improving the versatility of the battery replacement platform and reducing costs.

[0073] like Figure 3 As shown, the rear wheel positioning and alignment device 20 may also include at least one rear wheel rolling device 201, which is arranged on the mounting platform and located at the position where the rear wheel of the electric vehicle is parked. When the front wheel of the electric vehicle enters the position where the front wheel is parked, the positioning and alignment device 10 drives the telescopic part 12 to move through the first driving part 11, thereby realizing the positioning of the front wheel of the electric vehicle; at this time, the rear wheel of the electric vehicle enters the rear wheel rolling device 201, and the rear wheel positioning and alignment device 20 drives the telescopic part 12 to move through the first driving part 11, and at the same time, with the assistance of the rear wheel rolling device 201, the rear wheel of the electric vehicle is positioned, and accurate positioning is more convenient, which is more conducive to the stability of the battery replacement operation. In this embodiment, the number of the rear wheel rolling devices 201 is two, and the two rear wheel rolling devices 201 are respectively arranged at the positions where the two rear wheels of the electric vehicle are parked.

[0074] In this embodiment, the first driving part 11 in the first positioning member 1 includes a driving motor and a reducer. Of course, in other embodiments, the first driving part 11 can also be a moving driving mechanism that drives the telescopic part 12 to move by gas, liquid or electricity.

[0075] In this embodiment, the telescopic part 12 includes a first telescopic part 121 and a second telescopic part 122, and the first telescopic part 121 and the second telescopic part 122 are used to abut against the left wheel and the right wheel of the electric vehicle, respectively. The first driving part 11 will be connected to the first telescopic part 121 and the second telescopic part 122 at the same time and drive the first telescopic part 121 and the second telescopic part 122 to move at the same time. When it is necessary to abut against and push the electric vehicle, the first driving part 11 will simultaneously drive the first telescopic part 121 and the second telescopic part 122 to move and abut against the left wheel and the right wheel of the electric vehicle, respectively. After positioning and replacing the battery, the first driving part 11 will simultaneously drive the first telescopic part 121 and the second telescopic part 122 to move in a direction away from the wheel of the electric vehicle, thereby enabling the electric vehicle to walk on the battery replacement platform. In this embodiment, the first telescopic part and the second telescopic part are driven by the same first driving part. In other embodiments, the first telescopic part and the second telescopic part can also be driven by two driving parts respectively.

[0076] It should be particularly noted that when the electric vehicle is parked on the battery replacement platform and there is a deviation in the left and right directions, that is, when there is a deviation in the width direction of the vehicle body, the first drive unit 11 will simultaneously drive the first telescopic unit 121 and the second telescopic unit 122 to move and respectively abut against the left and right wheels of the electric vehicle. There will inevitably be a sequence in the process of the first telescopic unit 121 and the second telescopic unit 122 abutting against the left and right wheels of the electric vehicle. However, driven by the first drive unit 11, the abutting force of the first telescopic unit 121 or the second telescopic unit 122 drives the electric vehicle to move left and right, and finally the first telescopic unit 121 and the second telescopic unit 122 abut against the left and right wheels of the electric vehicle at the same time, thereby further realizing precise positioning and ensuring that the longitudinal axes of electric vehicles of different models are consistent with the reference line, greatly improving the versatility of the battery replacement platform and reducing costs.

[0077] The telescopic part 12 includes a transmission member 123 and a supporting member, and the first driving part 11 is used to drive the transmission member 123 to move so as to drive the supporting member to approach the wheel and abut against the outer wall of the wheel. Under the driving force of the first driving part 11, the supporting member is moved by the transmission member 123, so that the movement of the supporting member is more stable, and the precise positioning of the electric vehicle is achieved. In this embodiment, the transmission member 123 is a screw rod, and the first driving part 11 drives the screw rod to rotate, so as to achieve the left and right movement of the supporting member on the screw rod.

[0078] The abutting component includes a connecting member 124 and a push rod 125. The push rod 125 is arranged on the connecting member 124, and the connecting member 124 is connected to the transmission member 123. The connecting member 124 is connected to the transmission member 123 and can move on the transmission member 123. The movement of the connecting member 124 will drive the push rod 125 to move together, so that the push rod 125 abuts against the outer wall of the wheel and pushes the electric vehicle to move and adjust. The push rod 125 is installed on the connecting member 124 through a connecting rod. The shape of the push rod 125 matches the shape of the groove of the limiting member 21, and abuts against the outer wall near the bottom of the wheel. On the one hand, it avoids the push rod 125 from directly acting on the wheel hub, causing the wheel hub to wear. On the other hand, the push rod 125 matches the shape of the groove of the limiting member 21 to avoid mutual interference with the limiting member 21.

[0079] A guide rail 127 extending in the width direction of the vehicle body is provided below the connector 124, and a slider 126 is provided at the bottom of the connector 124. The slider 126 moves on the guide rail 127 to guide the connector 124 to move in the width direction of the vehicle body. The guide rail 127 has a guiding function, and the connector 124 moves in the width direction of the vehicle body by moving the slider 126 on the guide rail 127, which effectively avoids the offset and dislocation of the abutting component during the movement, and further improves the precise positioning of the electric vehicle.

[0080] The connecting member 124 includes a bottom wall 1242 and a side wall 1241, the slider 126 is arranged on the bottom wall 1242, and the push rod 125 is connected to the side wall 1241. The bottom wall 1242 facilitates the installation and connection of the slider 126, so that the slider 126 moves on the guide rail 127 located below, and the side wall 1241 facilitates the installation and connection of the push rod 125, and the installation and connection strength is high, ensuring that the push rod 125 acts on the outer wall of the wheel. Among them, there are a number of reinforcing ribs between the bottom wall 1242 and the side wall 1241, which effectively strengthen the overall structural strength of the connecting member 124 and greatly improve the stability of the first positioning component 1.

[0081] In this embodiment, the push rod 125 can be a straight rod, or a V-shaped push rod. The outer surface of the push rod 125 is coated with a buffer layer. The buffer layer has a buffering protection effect, so that the push rod 125 will not cause damage to the wheel when the force is applied to the wheel, thereby improving the safety and stability of the battery replacement platform.

[0082] The positioning and straightening device 10 also includes a second positioning component 2, which includes a limiting portion 21 and a second driving portion. The limiting portion 21 is used to limit the wheel along the length direction of the vehicle body, and the second driving portion is used to drive the limiting portion 21 to move along the length direction of the vehicle body. The second driving portion will be used to drive the limiting portion 21 to move. When the electric vehicle enters the battery replacement platform, the wheel of the electric vehicle will stop at the limiting portion 21, and the limiting portion 21 will abut against the wheel of the electric vehicle to limit the wheel along the length direction of the vehicle body.

[0083] The positioning and straightening device 10 is used to position the electric vehicle along the width direction of the vehicle body through the first positioning component 1, and is used to limit the electric vehicle along the length direction of the vehicle body through the second positioning component 2, so that the battery replacement platform can position the wheels of the electric vehicle along the length and width directions of the vehicle body. The electric vehicle is further accurately positioned on the battery replacement platform, which greatly improves the stability during the battery replacement process.

[0084] The limiting part 21 includes a front limiting clamping part 211 and a rear limiting clamping part 212, and the front limiting clamping part 211 and the rear limiting clamping part 212 form a V-shaped groove for limiting and clamping the wheel along the length direction of the vehicle body. When the wheel of the electric vehicle drives forward onto the battery replacement platform, the wheel will enter the V-shaped groove, and the front limiting clamping part 211 and the rear limiting clamping part 212 will abut against the outer peripheral surface of the wheel, thereby clamping and limiting the wheel along the length direction of the vehicle body, effectively avoiding the displacement and dislocation of the electric vehicle during the battery replacement process, and further improving the precise positioning of the electric vehicle.

[0085] Among them, the front limit clamping part 211 and the rear limit clamping part 212 can be driven by the same second driving part. That is, one second driving part is used to simultaneously drive the front limit clamping part 211 and the rear limit clamping part 212 to move, and the size and position of the V-shaped groove can be adjusted to achieve clamping and limiting for wheels of different sizes and electric vehicles of different models. Of course, the front limit clamping part 211 and the rear limit clamping part 212 can also be driven separately by two second driving parts.

[0086] The front limit clamping part 211 and the rear limit clamping part 212 have an inclined guide surface 213 on the side facing the wheel, which is used to guide the wheel to drive in or out. The inclined guide surface 213 is provided with a roller that can roll perpendicular to the direction of the wheel's driving in. The inclined guide surface 213 will abut against the outer peripheral surface of the wheel and is used to clamp and limit the wheel, and the wheel will directly contact and abut against the roller. When the first positioning component 1 positions the electric vehicle along the width direction of the vehicle body, the wheel will move left and right in the V-shaped groove, and the roller makes it easy for the wheel to move, thereby achieving precise positioning. Preferably, the angle between the inclined guide surface 213 and the horizontal plane is 100-170 degrees.

[0087] The limiting part 21 and the first positioning component 1 are connected to the second driving part through the mounting bracket, and the second driving part drives the limiting part 21 and the first positioning component 1 to move synchronously along the length direction of the vehicle body. When the second driving part drives the limiting part 21 to move along the length direction of the vehicle body, it will also drive the first positioning component 1 to move forward and backward, so that the push rod 125 will accurately abut against the predetermined position of the wheel without offset or misalignment, greatly improving the safety and stability of the battery replacement platform.

[0088] In this embodiment, there are two limit parts 21, and the first positioning component 1 is located between the two limit parts 21. The positioning and alignment device 10 realizes accurate positioning of the two front wheels of the electric vehicle through the two limit parts 21 and the one first positioning component 1, and the rear wheel positioning and alignment device 20 realizes accurate positioning of the two rear wheels of the electric vehicle through the one first positioning component 1 and the two rear wheel rolling devices 201.

[0089] The embodiment of the present invention also discloses a battery swap station, which includes the battery swap platform as described above. By accurately positioning the electric vehicle on the battery swap platform for battery replacement, the longitudinal axis of the electric vehicle is ensured to be consistent with the reference line; at the same time, accurate positioning can be achieved for electric vehicles of different models, which greatly improves the versatility of the battery swap station and reduces costs.
