Description

[0001] This application is a divisional of the Chinese invention patent with application date of December 31, 2020, application number 202011635274.X, and name “Battery Transport System”. Technical Field

[0002] The invention relates to a battery transport system. Background Art

[0003] As the battery charging time of electric vehicles is limited, quick-swap electric vehicles have been accepted by more and more users. They only need to replace the depleted battery and install a fully charged battery in the battery swap station, saving a long battery charging time. The battery swap station is equipped with: battery swap equipment for battery removal or installation, battery transport equipment for transporting batteries, and charging equipment for charging batteries.

[0004] Existing battery transfer devices usually achieve lifting and movement through a guide mechanism, a transmission mechanism, and a drive mechanism, thereby transferring batteries between battery compartments. A Chinese patent application with publication number CN110901601 A discloses an AGV charging station, which adopts the principle of multi-axis linkage and the design of a multi-axis system, specifically exchanges and charges batteries in the X-axis, Y-axis, Z-axis, and battery pulling and pushing directions, removes batteries from the AGV trolley, and delivers batteries to a load-bearing frame.

[0005] However, the transfer device disclosed in the above-mentioned prior art has a complex structure, low flexibility, and is not easy to expand, which limits its scope of application; moreover, the entire lifting process lacks stability and is prone to tilting, jamming, collision, etc., resulting in damage to the equipment.

[0006] In the prior art, there is also a method of lifting and lowering the car containing the battery by using a sprocket chain structure, but this structure has high requirements for the guide mechanism and requires regular maintenance (such as oiling). Moreover, after long-term use, the wear of the sprocket chain can easily affect the positioning accuracy, resulting in inaccurate positioning between the car and the battery compartment. In addition, the fixed application range of the sprocket chain structure is relatively narrow, which is not convenient for the expansion design of the battery rack and the battery swap station.

[0026] In this solution, the driving force of the driving mechanism can be transmitted to the driving wheel through the intermediate transmission part, and the position of the driving wheel can also be adjusted to make the driving wheel closer to the transition wheel, making the structure more compact and improving the stability of the transmission.

[0027] Preferably, the number of the driving mechanisms is four, and the four driving mechanisms are connected to the four vertical transmission mechanisms in a one-to-one correspondence.

[0063] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0064] The embodiment of the present invention provides a battery transport system 1, which can be used to transport batteries of electric vehicles. Specifically, the battery transport system 1 can include a battery transport device 10 and a battery rack 20 having a plurality of battery positions 22. The battery transport device 10 can be used to transport batteries between the plurality of battery positions 22 arranged in the vertical direction of the battery rack 20. Figure 4 As shown, the battery slots 22 are arranged on the battery rack 20 in sequence from bottom to top, and each battery slot 22 can be used to accommodate and charge batteries. The battery transfer system 1 can be moved to one side of the access opening of the battery slot 22 to place the battery into the battery slot 22 or take the battery out of the battery slot 22, thereby realizing the transfer of batteries between multiple battery slots 22.

[0065] like Figure 1-3 As shown, the battery rack 20 has a guide mechanism arranged in the vertical direction, and a plurality of battery positions 22 are arranged in sequence on the battery rack 20 in the vertical direction. The battery transfer equipment 10 includes a battery picking and placing mechanism 100 for picking and placing batteries from the battery positions 22 and at least two vertical transmission mechanisms 200. The vertical transmission mechanism 200 is used to drive the battery picking and placing mechanism 100 to realize vertical lifting and lowering movement along the guide mechanism.

[0066] The battery pick-and-place mechanism 100 is driven to move up and down along the guide mechanism by the transmission mechanism, and the guide mechanism of the battery rack 20 is arranged along the vertical direction, so that the battery pick-and-place mechanism 100 can move to the corresponding battery compartment 22 to pick and place the battery, which can improve the pick-and-place efficiency. In addition, the battery pick-and-place mechanism 100 can be smoothly moved up and down between the battery compartments 22 by at least two vertical transmission mechanisms 200.

[0067] As a preferred embodiment, at least one vertical transmission mechanism 200 is respectively provided on both sides of the battery pick-and-place mechanism 100. The two sides of the battery pick-and-place mechanism 100 refer to the two sides with the extension direction of the battery pick-and-place mechanism 100 as the axis. Thus, both sides of the battery pick-and-place mechanism 100 can be transmitted, thereby improving the stability of the movement of the battery pick-and-place mechanism 100.

[0068] As a preferred implementation method, Figure 1-3 As shown, the guide mechanism includes four guide posts 700 which are arranged in a one-to-one correspondence with the four ends of the battery transport device 10 , and the four vertical transmission mechanisms 200 are connected to the four guide posts 700 in a one-to-one correspondence.

[0069] In a specific implementation, vertical transmission mechanisms 200 may be provided at the four ends of the battery transport device 10, and accordingly, each vertical transmission mechanism 200 corresponds to a guide column 700 or other components having a guide surface, so that the four ends of the battery transport device 10 can be driven and guided, thereby improving the lifting and lowering stability of the battery transport device 10.

[0070] As another preferred embodiment, the guide mechanism includes two guide posts 700 disposed on opposite sides of the battery transport device 10 , and the two vertical transmission mechanisms 200 are connected to the two guide posts 700 in a one-to-one correspondence.

[0071] In a specific implementation, the guide mechanism may also have two guide posts 700, which are respectively arranged on both sides of the battery pick-and-place mechanism 100, so as to guide the battery pick-and-place mechanism 100 to rise and fall. The two guide posts 700 are preferably placed in the middle of the battery pick-and-place mechanism 100 to make the guidance more stable.

[0072] As a preferred embodiment, the battery transport device 10 further includes at least one driving mechanism 800, which is connected to the vertical transmission mechanism 200 and is used to drive the vertical transmission mechanism 200 to drive the battery pick-and-place mechanism 100 to move up and down, thereby realizing automatic lifting control.

[0073] As a preferred implementation method, Figure 1-3 As shown, there are two driving mechanisms 800 , which are arranged along the telescopic direction of the battery pick-and-place mechanism 100 , and are respectively connected to the front and rear vertical transmission mechanisms 200 in the telescopic direction.

[0074] In a specific implementation, the battery transport device 10 includes two driving mechanisms 800, and the number of transmission mechanisms is four, and the four transmission mechanisms are respectively arranged at the four ends of the battery pick-and-place mechanism 100, that is, a vertical transmission mechanism 200 is arranged at the front and rear of the battery pick-and-place mechanism 100 on one side. The driving mechanism 800 can drive the front and rear vertical transmission mechanisms 200 respectively, thereby driving the lifting and lowering movement of the battery pick-and-place mechanism 100.

[0075] As a preferred embodiment, two driving mechanisms 800 are arranged on the top of the battery placement mechanism 100 in opposite directions along the extension and retraction directions, and the output end of each driving mechanism 800 is connected to the vertical transmission mechanisms 200 on the corresponding two sides through a coaxial connector 900.

[0076] In specific implementation, the driving mechanism 800 is connected to two transmission mechanisms arranged opposite to each other along the extension direction of the battery pick-up and placement mechanism 100 through a coaxial connector 900. Two driving mechanisms 800 are provided so that the two transmission mechanisms corresponding to each driving mechanism 800 can be synchronously driven, which simplifies the overall structure of the driving mechanism 800 and improves the stability during the lifting and moving process. Figure 3 As shown, the driving mechanism 800 can be arranged on the same side above the battery pick-and-place mechanism 100; Figure 1 and Figure 2 As shown, it can also be located in the middle position above the battery pick-and-place mechanism 100. Therefore, the driving mechanism 800 is located above the side of the battery pick-and-place mechanism 100 and does not interfere with the operation of the battery pick-and-place mechanism 100. The driving mechanism 800 can be a driving motor.

[0077] Specifically, Figure 3 As shown, the side of the battery access mechanism 100 has a longitudinal plate 110, and the two driving mechanisms 800 are respectively fixed on the inner side of the longitudinal plate 110 away from the battery access mechanism 100. Wherein, away from the battery access mechanism 100 means away from the battery access mechanism 100 in the vertical direction. Further, the driving mechanism 800 is arranged on the inner side of the longitudinal plate 110, which is conducive to protecting the driving mechanism 800, avoiding the driving mechanism 800 from scratching other components arranged on the guide mechanism, and improving safety.

[0078] Specifically, Figure 1 and Figure 2As shown, the top of the battery pick-and-place mechanism 100 has a transverse plate 120, and two drive mechanisms 800 are evenly arranged on the transverse plate 120 along the length direction of the battery pick-and-place mechanism 100. By arranging the transverse plate 120 at the top, the drive mechanism 800 is arranged at the top of the battery pick-and-place mechanism 100; the uniform arrangement along the length direction makes the battery pick-and-place mechanism 100 more evenly stressed, thereby making the battery pick-and-place mechanism 100 more stable during the lifting process. In this embodiment, the length direction of the battery pick-and-place mechanism 100 is the direction in which the transmission mechanisms on both sides extend.

[0079] In specific implementation, Figure 1 and Figure 2 As shown, the battery transport device also includes a first fixing plate 310 fixed to the battery pick-and-place mechanism 100, and a second fixing plate 320 fixed to the first fixing plate 310 at a preset interval. The two ends of the transverse plate 120 are respectively connected to the inner side surfaces of the first fixing plates 310 on both sides, and the transverse plate 120 is connected to the upper edge of the first fixing plate 310, and the battery pick-and-place mechanism 100 is connected to the lower edge of the first fixing plate 310. In a specific implementation, the transmission mechanism 200 can be arranged between the first fixing plate 310 and the second fixing plate 320, which is convenient for installing and arranging the transmission mechanism 200, and can also protect the transmission mechanism 200 to a certain extent; and when the intermediate transmission part 600 is subsequently installed, the intermediate transmission part 600 can also be connected to both the first fixing plate 310 and the second fixing plate 320 to avoid the appearance of a cantilever structure, so that the force is balanced and the connection is more reliable.

[0080] Through the above arrangement of the drive mechanism 800, the drive mechanism 800 can be set to be fixedly connected to the battery pick-up and placement mechanism 100 and move synchronously therewith, so that the drive mechanism 800 and the battery pick-up and placement mechanism 100 can constitute a complete electromechanical product. When debugging or maintenance is required, the drive mechanism 800 and the battery pick-up and placement mechanism 100 can be directly operated as a whole without removing the motor or the battery pick-up and placement mechanism 100 from the battery transport equipment 10. Under the premise of ensuring mechanical strength, it is effectively convenient for the operator to debug or maintain the drive mechanism 800 or the battery pick-up and placement mechanism 100.

[0081] As a preferred implementation method, Figure 1 and Figure 2 As shown, the vertical transmission mechanism 200 includes a driving wheel 210, a transition wheel 220, and a transmission belt 230 fixed on the guide mechanism at both ends along the vertical direction. The driving wheel 210 and the transition wheel 220 are arranged on the battery pick-up and placement mechanism 100, and the transmission belt 230 passes between the driving wheel 210 and the transition wheel 220 to drive the battery pick-up and placement mechanism 100 to move up and down.

[0082] The two ends of the transmission belt 230 are fixedly connected to the guide mechanism, and the driving wheel 210 and the transmission belt 230 disposed on the battery pick-and-place mechanism 100 move relative to each other, thereby driving the battery pick-and-place mechanism 100 to move up and down; and the transition wheel 220 can make the transmission belt 230 at least partially sleeved on the driving wheel 210 for transmission; in addition, the lifting height of the battery pick-and-place mechanism 100 can be adjusted by changing the length of the transmission belt 230. The transmission mechanism has a simple structure, strong flexibility, a wide range of applications, and is also easy to expand in design.

[0083] As a preferred implementation method, Figure 1-3 As shown, the transition wheel 220 includes a first driven wheel 221 and a second driven wheel 222. The first driven wheel 221 and the second driven wheel 222 are arranged on both sides of the driving wheel 210 at a preset interval in the vertical direction, and the transmission belt 230 passes between the first driven wheel 221 and the driving wheel 210, and between the driving wheel 210 and the second driven wheel 222 in sequence.

[0084] In a specific implementation, the first driven wheel 221 and the second driven wheel 222 may be located between the driving wheel 210 and the guide mechanism, and the distance between the axis of the driving wheel 210 and the guide mechanism is smaller than the diameter of the first driven wheel 221 and the second driven wheel 222. Figure 1-3 As shown, the first driven wheel 221 and the second driven wheel 222 can be arranged on the upper and lower sides of the driving wheel 210. The transmission belt 230 passes through the gap between the first driven wheel 221 and the driving wheel 210, and after being wrapped on the driving wheel 210, it passes through the gap between the second driven wheel 222 and the driving wheel 210, so that the transmission belt 230 forms a shape similar to Ω, which can increase the wrap angle of the transmission belt 230 on the driving wheel 210 and improve the stability of the transmission. Correspondingly, by adjusting the distance between the first driven wheel 221 and the second driven wheel 222, the size of the wrap angle can also be adjusted. Specifically, the wrap angle value between the transmission belt 230 and the driving wheel 210 ranges from 120° to 230°.

[0085] In addition, the battery transfer equipment 1 needs to be raised and lowered during the process of taking and placing batteries. By respectively providing a first driven wheel 221 and a second driven wheel 222 on both sides, the transmission belt 230 and the driving wheel 210 can accurately transmit the power during the two movements of raising and lowering the battery transfer equipment 1, thereby improving the smoothness and accuracy of the movement.

[0086] As a preferred implementation method, Figure 1-3 As shown, the distance between the first driven wheel 221 and the second driven wheel 222 and the guide mechanism is set so that the transmission belt 230 can be pressed on the guide mechanism, and specifically can be pressed on the guide column 700. Thus, the transmission belt 230 can be more stable during the movement.

[0087] As a preferred embodiment, the gap value between the driving wheel 210 and the transition wheel 220 is between the first thickness value from the bottom of the meshing teeth of the transmission belt 230 to the other side and the second thickness value from the top of the meshing teeth to the other side. The other side refers to the side corresponding to the non-transmission surface of the transmission belt 230. As a result, the gap between the driving wheel 210 and the transition wheel 220 is greater than the thickness of the belt body of the transmission belt 230, and less than the overall thickness of the transmission belt 230, ensuring that the transmission belt 230 can fit between the driving wheel 210 and the transition wheel 220 during the transmission process to avoid tooth jumping. Specifically, when the driving wheel 210 transitions to the transition wheel 220, or when the transition wheel 220 transitions to the driving wheel 210, the transmission belt 230 can be prevented from jumping teeth, which is more stable and improves transmission accuracy.

[0088] As a preferred implementation method, Figure 1 and Figure 2 As shown, the battery transport device 10 further includes an intermediate transmission part 600, the input end of the intermediate transmission part 600 is connected to the output end of the driver of the battery transport device 10, and the output end of the intermediate transmission part 600 is connected to the driving wheel 210 to drive the driving wheel 210 to rotate, thereby driving the battery pick-and-place mechanism 100 to move up and down. Thus, the driving force of the driving mechanism 800 can be transmitted to the driving wheel 210 through the intermediate transmission part 600, and the position of the driving wheel 210 can also be adjusted to make the driving wheel 210 closer to the transition wheel 220, so that the structure is more compact and the stability of the transmission is improved.

[0089] In specific implementation, Figure 1 and Figure 2 As shown, the transmission mechanism is disposed between the first fixing plate and the second fixing plate, and the intermediate transmission part 600 can be disposed on the fixing plate closer to the battery pick-and-place mechanism 100 , so as to facilitate connection with the driving mechanism 800 located above the battery pick-and-place mechanism 100 .

[0090] As a preferred implementation method, Figure 1 and Figure 2 As shown, the intermediate transmission part 600 is a sprocket chain 630 structure, including a driving sprocket 610, a driven sprocket 620 and a chain 630. The driving sprocket 610 is connected to the output end of the driver, and the driven sprocket 620 is coaxially connected to the driving wheel 210 to drive the driving wheel 210 to rotate. The chain 630 is a closed-loop structure with its two ends respectively mounted on the driving sprocket 610 and the driven sprocket 620.

[0091] Furthermore, if Figure 1 As shown, the sprocket chain 630 structure further includes a tensioning sprocket 640 , which abuts against the chain 630 from the outside to adjust the tension of the tensioning sprocket 640 .

[0092] like Figure 1As shown, in a specific implementation, the sprocket chain 630 can be a multi-row chain structure.

[0093] As another preferred embodiment, the intermediate transmission part 600 is a gear set, including a driving gear and a driven gear, the driving gear is connected to the output end of the driver, the driven gear is coaxially connected to the driving wheel 210 to drive the driving wheel 210 to rotate, and the driving gear and the driven gear are meshed with each other.

[0094] As another preferred embodiment, the intermediate transmission part 600 is a pulley structure, including a first driving wheel, a driven wheel and a first belt. The first driving wheel is connected to the output end of the driver, and the driven wheel is coaxially connected to the driving wheel 210 to drive the driving wheel 210 to rotate. The first belt is a closed-loop structure with both ends mounted on the first driving wheel and the driven wheel.

[0095] In specific implementation, as mentioned above, the structure of the intermediate transmission part 600 can adopt various forms, and can be specifically configured accordingly according to the arrangement between the output shaft of the driving mechanism 800 and the driving wheel 210 .

[0096] In another preferred embodiment, the number of the driving mechanisms 800 can also be four, and the four driving mechanisms 800 are connected to the four vertical transmission mechanisms 200 in a one-to-one correspondence. Thus, each driving mechanism 800 independently controls the corresponding vertical transmission mechanism 200, achieving freedom and pertinence of control.

[0097] In a preferred embodiment, the battery transport system 1 further includes a control unit, which is respectively connected to the driving mechanisms 800 so as to achieve synchronous control of the multiple vertical transmission mechanisms 200 so that the battery pick-and-place mechanism 100 can be lifted and lowered smoothly.

[0098] As a preferred implementation method, Figure 4 As shown, a plurality of battery positions 22 are arranged in two rows of battery racks 20 at a preset interval, the battery transport device 10 is located between the two rows of battery racks 20, and the battery pick-up and placement mechanism 100 is arranged to be telescopically movable toward the battery positions 22 on both sides to pick up and place batteries. Furthermore, the four guide posts 700 reuse the four upright posts 21 of the two rows of battery racks 20 close to the battery transport device 10.

[0099] The guide mechanism reuses the columns 21 of the battery racks 20 on both sides, and the battery pick-and-place mechanism 100 can pick and place batteries from the battery racks 20 on both sides, which can not only improve the pick-and-place efficiency, but also save resources of the battery pick-and-place mechanism 100. In addition, the space between the battery rack 20 and the battery pick-and-place mechanism 100 is more compact, further reducing the occupied area.

[0100] As a preferred implementation, the reused column 21 has a transmission surface that matches with the transmission mechanism 200 , and / or the reused column 21 has a guide surface that matches with the battery placement mechanism 100 .

[0101] In specific implementation, Figure 2 and Figure 3 As shown, the column 21 has multiple side walls, one or more of which can be used as a transmission surface or a guide surface. The transmission surface refers to the side wall surface used to fix the transmission mechanism 200, which is the transmission belt 230 in the embodiment of the present invention, and the guide surface refers to the side wall surface used for the lifting and lowering guidance of the battery pick-and-place mechanism 100. In this way, the installation of the transmission mechanism 200 and the guidance of the battery pick-and-place mechanism 100 can be achieved, the overall structure is simplified, the connection between the two is more compact, and the guiding strength can be improved, the cost can be reduced, the installation process saves manpower and material resources, and the operating efficiency of the entire system is improved.
