Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery pack replacement equipment, and particularly relates to a stacking equipment and a battery replacement station. BACKGROUND

[0002] In the process of quick battery replacement of an electric vehicle, a battery pack to be charged needs to be taken off and placed on a charging rack, and a battery pack that has been fully charged needs to be replaced on the electric vehicle. At this time, a stacking equipment is needed to place the battery pack to be charged taken off by the battery replacement mobile platform into the charging rack, and to take the replacement battery pack off the charging rack and place it on the battery replacement mobile platform. When the stacking equipment is transferring the battery pack, a transfer arm is needed to take and place the battery pack, and the working stroke of the transfer arm determines the transfer distance of the battery pack. The early-built battery replacement station was designed for battery packs with low capacity and small size, and the transfer path of the battery pack was relatively short. With the progress of battery pack manufacturing and the demand for the cruising range of new energy vehicles, the size of the battery pack is getting larger and larger, and more and more battery packs need to be replaced and charged, so the transfer arm needs to provide a larger transfer stroke to take and place the battery pack, which makes the existing stacking equipment unable to meet the transfer stroke requirement of the battery pack. At present, it is often considered to rebuild the battery replacement station. Because of the increase in the size of the battery pack, the existing stacking equipment needs to be replaced with a larger stacking equipment, but the structure of the original battery replacement station is relatively compact, and it is difficult to accommodate a larger stacking equipment, so a new battery replacement station needs to be built, which greatly increases the construction cost and operation cost of the battery replacement station, and also causes the frequency of the original battery replacement station to be greatly reduced and the battery replacement capacity to be wasted. CONTENT OF THE UTILITY MODEL

[0003] The application provides a stacking equipment and a battery replacement station to solve the technical problem of difficulty in battery replacement caused by insufficient transfer stroke of the traditional stacking equipment.

[0004] The technical scheme adopted by the application is as follows:

[0005] A stacking equipment, comprising a support frame and a transfer arm arranged on the support frame, the transfer arm being capable of extending and retracting relative to the support frame to transfer a battery pack, further comprising a driving member and a supporting tray, an output shaft of the driving member being connected with the supporting tray, the supporting tray being arranged on the support frame and being arranged in a horizontal direction away from the transfer arm, the supporting tray being capable of moving in a vertical direction under the drive of the driving member and having a supporting position higher than an upper surface of the transfer arm and an initial position lower than the upper surface of the transfer arm, so that the battery pack can be transferred to the supporting tray or the transfer arm.

[0006] The stacking equipment of the present application is provided with a lifting device. In the process of transferring the battery pack, when the stroke of the transfer arm is not enough to send the battery pack to the preset position, the transfer arm can first transport the battery pack for a certain stroke. When the transfer arm reaches the maximum stroke and cannot continue to transport the battery pack, the driving member works and lifts the support tray through the output shaft, so that the support tray moves from the initial position to the support position. With the upward movement of the support tray, it will abut against and support the battery pack and separate from the transfer arm. At this time, the transfer arm retracts, the driving member controls the output shaft to retract, and the support tray moves from the support position to the initial position. In the process of moving from the support position to the initial position, the battery pack will fall onto the transfer arm. In this way, the transfer arm has a certain conveying stroke to transfer the battery pack. That is, the lifting device of the present application can increase the conveying stroke of the transfer arm, realize the applicability of the transfer arm to battery packs with different conveying stroke requirements, and meet the battery replacement needs of battery replacement vehicles with different battery pack sizes.

[0007] The stacking equipment described in the present application further comprises the following additional technical features:

[0008] The driving member is arranged below the support tray, and the output shaft extends and retracts in the vertical direction to drive the support tray to switch between the initial position and the support position.

[0009] Arranging the driving member below the support tray can avoid occupying the space above the support tray, thereby avoiding interference of the driving member with the battery pack above the support tray, providing a guarantee for stable support of the battery pack by the support tray. Since the support tray and the transfer arm are arranged in a horizontal direction, the driving member arranged below the support tray can also avoid interfering with the transfer work of the transfer arm, while fully utilizing the lower space of the transfer arm and the support tray, realizing a reasonable layout of the stacking equipment, optimizing the structure of the stacking equipment, and helping to miniaturize the stacking equipment. On this basis, the output shaft moves in the vertical direction, which on the one hand shortens the working length required for the output shaft to drive the support tray to switch between the initial position and the support position, helping to improve the driving efficiency of the driving member; on the other hand, the output shaft moves in the vertical direction, so that the support point of the output shaft to the support tray coincides with the movement direction of the output shaft, thereby greatly improving the stability of the movement process of the support tray.

[0010] The driving member has a plurality of driving members arranged in a spaced manner and connected to the support tray respectively to jointly drive the support tray to switch between the support position and the initial position; or the driving member and the support tray each have a plurality of driving members and support trays, the plurality of support trays are arranged in a spaced manner, and each support tray is connected below to a corresponding driving member, so that each support tray can be driven to the support position or the initial position by the corresponding driving member.

[0011] The plurality of driving members can improve the uniformity of supporting the supporting tray, so that the supporting tray is relatively stable under the action of the plurality of driving members when switching between the initial position and the supporting position, and the phenomenon of the supporting tray tilting and overturning due to uneven distribution of supporting points is avoided. The number of driving members and supporting trays is both set to be multiple, and a driving member is arranged below each supporting tray, so that the battery pack uniformly rises or falls under the supporting action of the plurality of supporting trays, and the battery pack is prevented from sliding off the supporting tray.

[0012] Each of the driving members has a plurality of output shafts arranged at intervals, and the bottom surface of the supporting tray is fixed with a connecting plate connected with the plurality of output shafts to drive the supporting tray to move in the vertical direction.

[0013] The connecting plate arranged at the bottom of the supporting tray mainly plays a stress dispersion role, improves the abutment area of the output shaft and the bottom of the supporting tray, and uniformly applies the pushing force applied to the supporting tray by the connecting plate during the upward and downward movement of the supporting tray driven by the output shaft, thereby reducing the possibility of stress concentration at the abutment position of the output shaft and the supporting tray. In addition, a plurality of output shafts are arranged on each driving member, which improves the stability of the output shaft in supporting the connecting plate, and in turn improves the stability of the driving member in driving the upward and downward movement of the supporting tray.

[0014] The driving member is provided with a limiting column extending in the vertical direction, and the connecting plate is provided with a limiting through slot matched with the limiting column, the limiting column is arranged in the limiting through slot and abuts with the inner wall of the limiting through slot to guide the connecting plate to move in the vertical direction along with the output shaft.

[0015] When the supporting tray is subjected to a biasing force due to the placement position of the battery pack or other factors, there may be a tendency to tilt to one side. When the supporting tray has a tilting tendency, a certain eccentric force will be applied to the output shaft. By arranging the limiting column and the limiting through slot, the output shaft can only move in the extension direction of the limiting through slot, preventing the output shaft from tilting under the action of the eccentric force applied by the supporting tray, which helps to improve the stability of the output shaft in driving the supporting tray to move in the vertical direction.

[0016] A vertically arranged guide column is further arranged between the supporting frame and the supporting tray, and the guide column includes a guide column and a guide sleeve matched with each other. The guide column is mounted on one of the supporting frame and the supporting tray, and the guide sleeve is mounted on the other one of the supporting frame and the supporting tray to guide the supporting tray to move in the vertical direction.

[0017] By setting the guide column and the guide sleeve, the switching of the supporting tray between the initial position and the supporting position can be guided, so that the supporting tray moves along the extension direction of the guide sleeve, and the supporting tray is prevented from being deviated during movement due to the placement position of the battery pack or other factors, which helps to improve the stability of the supporting tray in supporting the battery pack and prevent the imbalance and falling of the battery pack caused by uneven supporting force of the supporting tray.

[0018] The bottom wall of the supporting tray is provided with a positioning disc, and the guide column is installed on the positioning disc.

[0019] By setting the positioning disc, a mounting position is provided for the guide column, and when the supporting tray is lowered from the supporting position to the initial position, the top wall of the guide sleeve abuts against the positioning disc, that is, the guide sleeve supports the supporting tray through the positioning disc, which increases the contact area between the guide sleeve and the supporting tray and prevents stress concentration at the contact position of the guide sleeve and the supporting tray.

[0020] The driving member and the guide column are both provided with two, and the two driving members and the two guide columns are diagonally arranged.

[0021] By setting the number of driving members and guide columns to two, the supporting tray can stably support the battery pack under the combined support of the driving members and the guide columns; since the supporting tray is raised or lowered under the driving action of the driving members, the guide column only plays a guiding role, and the output shaft of the driving member actually supports the supporting tray, therefore, the driving members and the guide columns are diagonally arranged, so that the driving members drive the supporting tray more evenly and prevent the supporting tray from being deviated due to uneven stress.

[0022] The supporting tray is provided with a groove in the length direction or the width direction of the supporting frame, and the groove is recessed inward from the outer edge of the two ends of the supporting tray.

[0023] The groove provided on the supporting tray reduces the actual area of the supporting tray on the basis of ensuring that the supporting tray has sufficient supporting area for the battery pack to stably support the battery pack, which helps to reduce the manufacturing cost of the supporting tray; in addition, the groove exposes the driving member below the supporting tray, which is convenient for workers to intuitively observe the working state of the driving member, and provides an operation space for the operator when the driving member is overhauled or replaced.

[0024] The application also provides a battery swap station, which comprises a charging frame and the stacking device as described above.

[0025] The battery swap station of the present application has good adaptability to battery packs of different sizes and different transfer mileage requirements, and can better meet the battery swap requirements of the battery swap vehicle

[0026] As the above technical solutions are adopted, the present application has the following beneficial effects:

[0027] 1. The stacking equipment of the present application is provided with a lifting device. In the process of transferring the battery pack, when the stroke of the transfer arm is not enough to send the battery pack to the preset position, the transfer arm can first transport the battery pack for a part of the stroke. When the transfer arm reaches the maximum stroke and cannot continue to transport the battery pack, the driving member works and lifts the support tray through the output shaft, so that the support tray moves from the initial position to the support position. With the upward movement of the support tray, it will abut against and support the battery pack and separate from the transfer arm. At this time, the transfer arm retracts, the driving member controls the output shaft to retract, and the support tray moves from the support position to the initial position. In the process of moving the support tray from the support position to the initial position, the battery pack will fall onto the transfer arm. In this way, the transfer arm has a certain conveying stroke to transfer the battery pack. That is, the lifting device of the present application can increase the conveying stroke of the transfer arm, realize the applicability of the transfer arm to battery packs with different conveying stroke requirements, and meet the battery swap requirements of the battery swap vehicle with different battery pack sizes.

[0028] 2. As a preferred embodiment of the present application, the driving member is arranged below the support tray, which can avoid the occupation of the space above the support tray by the driving member, thereby avoiding the interference of the driving member with the battery pack above the support tray and providing a guarantee for the stable support of the battery pack by the support tray. Moreover, since the support tray and the transfer arm are arranged in a horizontal direction, the driving member arranged below the support tray can also avoid interfering with the transfer work of the transfer arm, while fully utilizing the lower space of the transfer arm and the support tray, realizing the reasonable layout of the stacking equipment, optimizing the structural form of the stacking equipment, and helping to miniaturize the stacking equipment. On this basis, the output shaft moves in the vertical direction, which on the one hand shortens the working length required for the output shaft to drive the support tray to switch between the initial position and the support position, and helps to improve the driving efficiency of the driving member; on the other hand, the movement of the output shaft in the vertical direction makes the support point of the output shaft to the support tray coincide with the movement direction of the output shaft, thereby greatly improving the stability of the movement process of the support tray.

[0047] As shown in Figure 1 , Figure 4 A palletizing device includes a support frame 6 and a transfer arm 7 arranged on the support frame 6, the transfer arm 7 being capable of extending and retracting relative to the support frame 6 to transfer battery packs, further including a driving member 1 and a supporting tray 2, an output shaft 3 of the driving member 1 being connected with the supporting tray 2, the supporting tray 2 being arranged on the support frame 6 and being arranged in a horizontal direction with the transfer arm 7, the supporting tray 2 being capable of moving in a vertical direction under the driving of the driving member 1 and having a supporting position higher than an upper surface of the transfer arm 7 and an initial position lower than the upper surface of the transfer arm 7, so that the battery packs can be transferred to the supporting tray 2 or the transfer arm 7.

[0048] The stacking equipment of the present application is provided with a lifting device. In the process of transferring the battery pack, when the stroke of the transfer arm 7 is not enough to send the battery pack to the preset position, the transfer arm 7 can first transport the battery pack for a partial stroke. When the transfer arm 7 reaches the maximum stroke and cannot continue to transport the battery pack, the driving member 1 works and lifts the support tray 2 through the output shaft 3, so that the support tray 2 moves from the initial position to the supporting position. With the upward movement of the support tray 2, it will abut against and support the battery pack and separate from the transfer arm 7. At this time, the transfer arm 7 retracts, the driving member 1 controls the output shaft 3 to retract, and the support tray 2 moves from the supporting position to the initial position. In the process of moving the support tray 2 from the supporting position to the initial position, the battery pack will fall onto the transfer arm 7. In this way, the transfer arm 7 has a certain conveying stroke to transfer the battery pack. That is, the lifting device of the present application can increase the conveying stroke of the transfer arm 7, realize the applicability of the transfer arm 7 to battery packs with different conveying stroke requirements, and meet the battery replacement needs of battery replacement vehicles with different battery pack sizes.

[0049] The present application does not limit the structure of the driving member 1. In one embodiment, the driving member 1 can adopt a thin cylinder, and the output shaft 3 is the piston rod of the thin cylinder; in another embodiment, the driving member 1 can adopt a hydraulic cylinder or a linear motor, etc.

[0050] As a preferred embodiment of the present application, as shown in Figure 1 The driving member 1 is arranged below the support tray 2, and the output shaft 3 extends and retracts in the vertical direction to drive the support tray 2 to switch between the initial position and the supporting position.

[0051] Arranging the driving member 1 below the support tray 2 can avoid the occupation of the space above the support tray 2 by the driving member 1, thereby avoiding the interference of the driving member 1 with the battery pack above the support tray 2, providing a guarantee for the stable support of the battery pack by the support tray 2. Moreover, since the support tray 2 and the transfer arm 7 are arranged in a horizontal direction, the driving member 1 arranged below the support tray 2 can also avoid interfering with the transfer work of the transfer arm 7, while fully utilizing the lower space of the transfer arm 7 and the support tray 2, realizing the reasonable layout of the stacking equipment, optimizing the structure of the stacking equipment, and helping to miniaturize the stacking equipment. On this basis, the output shaft 3 moves in the vertical direction, on the one hand, shortening the working length required for the output shaft 3 to drive the support tray 2 to switch between the initial position and the supporting position, and helping to improve the driving efficiency of the driving member 1; on the other hand, the output shaft 3 moves in the vertical direction, so that the support point of the output shaft 3 to the support tray 2 coincides with the movement direction of the output shaft 3, thereby greatly improving the stability of the support tray 2 during movement.

[0052] The present embodiment does not limit the number of driving members 1 and support trays 2, which can adopt any of the following embodiments:

[0053] Example 1: As Figure 1 As shown, there are multiple drive components 1, which are spaced apart and connected to the support tray 2 respectively, so as to jointly drive the support tray 2 to switch between the support position and the initial position. Setting multiple drive components 1 can improve the uniformity of support for the support tray 2, so that the support tray 2 can switch between the initial position and the support position more stably under the action of multiple drive components 1, and avoid the tilting and overturning of the support tray 2 caused by uneven distribution of support points.

[0054] Example 2: Multiple drive units and support trays are used, with the support trays spaced apart. Each support tray is connected to a corresponding drive unit, allowing each support tray to be moved to its supporting position or initial position by the corresponding drive unit. By using multiple drive units and support trays, and placing a drive unit under each support tray, the battery pack rises or falls at a uniform speed under the support of the multiple support trays, preventing the battery pack from slipping off the support trays.

[0055] Preferably, each driving component has multiple output shafts spaced apart. A connecting plate 21 is fixed to the bottom surface of the support tray 2, and the connecting plate 21 is connected to the multiple output shafts to drive the support tray 2 to move vertically. The connecting plate 21 at the bottom of the support tray 2 mainly serves to disperse stress, increasing the contact area between the output shaft and the bottom of the support tray 2. During the up-and-down movement of the support tray 2 driven by the output shaft, the pushing force applied to the support tray 2 is evenly applied to the support tray 2 after being dispersed by the connecting plate 21, reducing the possibility of stress concentration at the contact point between the output shaft and the support tray 2. In addition, each driving component is provided with multiple output shafts 3, which improves the support stability of the output shafts 3 on the connecting plate 21, thereby improving the stability of the driving component driving the support tray 2 to move up and down.

[0056] This application does not limit the number of output shafts 3 on each drive component 1, and they can also be as follows: Figure 1 , Figure 2 Each drive unit 1 shown is equipped with an output shaft 3.

[0057] Furthermore, such as Figure 2As shown, the driving member 1 is provided with a limiting column 11 extending in the vertical direction, and the connecting plate 21 is provided with a limiting through slot 211 corresponding to the limiting column 11, the limiting column 11 is arranged in the limiting through slot 211 and abuts against the inner wall of the limiting through slot 211 to guide the connecting plate 21 to move along the vertical direction with the output shaft 3. When the bearing tray 2 is subjected to the biasing force due to the placement position of the battery pack or other factors, it may have a tendency to tilt to one side, and when the bearing tray 2 has a tilting tendency, a certain eccentric force will be applied to the output shaft 3; by arranging the limiting column 11 and the limiting through slot 211, the movement of the output shaft 3 is limited to the extending direction of the limiting through slot 211, preventing the output shaft 3 from tilting under the eccentric force applied by the bearing tray 2, which helps to improve the stability of the movement of the output shaft 3 along the vertical direction with the bearing tray 2.

[0058] As a preferred embodiment of the present application, as shown in Figure 1 As shown, a vertical guide column 4 is arranged between the support frame 6 and the bearing tray 2, the guide column 4 includes a guide column 4 and a guide sleeve 5 matched with each other, the guide column 4 is arranged on one of the support frame 6 and the bearing tray 2, and the guide sleeve 5 is arranged on the other one of the support frame 6 and the bearing tray 2 to guide the movement of the bearing tray 2 along the vertical direction.

[0059] By arranging the guide column 4 and the guide sleeve 5, the switching of the bearing tray 2 between the initial position and the bearing position can be guided, so that the bearing tray 2 moves along the extending direction of the guide sleeve 5, avoiding the movement bias of the bearing tray 2 due to the placement position of the battery pack or other factors during the movement, which helps to improve the bearing stability of the bearing tray 2 to the battery pack and avoid the imbalance and falling of the battery pack due to the uneven bearing force applied by the bearing tray 2.

[0060] As a preferred embodiment of the present embodiment, as shown in Figure 1 As shown, the bottom wall of the bearing tray 2 is provided with a positioning disc 22, and the guide column 4 is arranged on the positioning disc 22, and when the bearing tray 2 is in the initial position, the positioning disc 22 abuts against the top wall of the guide sleeve 5.

[0061] By arranging the positioning disc 22, a mounting position is provided for the guide column 4, and when the bearing tray 2 is lowered from the bearing position to the initial position, the top wall of the guide sleeve 5 abuts against the positioning disc 22, that is, the guide sleeve 5 supports the bearing tray 2 through the positioning disc 22, which increases the contact area between the guide sleeve 5 and the bearing tray 2 and avoids the possibility of stress concentration at the contact position of the guide sleeve 5 and the bearing tray 2.

[0062] Preferably, the guide sleeve 5 is a linear bearing arranged on the support frame 6.

[0063] As another preferred embodiment of the present embodiment, as shown in Figure 1As shown, the driving member 1 and the guide column 4 are both provided with two, and the two driving members 1 and the two guide columns 4 are diagonally arranged. By setting the number of the driving member 1 and the guide column 4 to two, the support tray 2 can be stably loaded with the battery pack under the common support of the driving member 1 and the guide column 4; since the support tray 2 is driven to rise or fall by the driving member 1, the guide column 4 only plays a role of movement guidance, and the output shaft 3 of the driving member 1 actually supports the support tray 2, therefore, the driving member 1 and the guide column 4 are diagonally arranged, so that the driving member 1 drives the support tray 2 more evenly, preventing the movement deviation of the support tray 2 caused by uneven force.

[0064] The number and arrangement position of the driving member and the guide column are not limited in the embodiment, in another embodiment, the number of the driving member is one and is arranged at the middle of the support tray, and the number of the guide column is multiple and is distributed around the driving member; in one embodiment, the number of the guide column is one and is arranged at the middle of the support tray, and the number of the driving member 1 is multiple and is distributed around the guide column.

[0065] As a preferred embodiment of the present application, as shown in Figure 3 As shown, the support tray 2 is provided with a groove 23 along the length direction or the width direction of the support frame 6, and the groove 23 is recessed inward from the outer edge of the two ends of the support tray 2. The groove 23 arranged on the support tray 2 reduces the actual area of the support tray 2 on the basis of ensuring that the support tray 2 has enough support area for the battery pack so that the battery pack can stably move up and down, which helps to reduce the manufacturing cost of the support tray 2; in addition, the arrangement of the groove 23 exposes the driving member 1 below the support tray 2, which is convenient for the staff to intuitively observe the working state of the driving member 1, and when the driving member 1 is overhauled or replaced, the groove 23 provides an operation space for the operator.

[0066] The present application also provides a battery swap station, which comprises a charging frame and the stacking device as described above. The battery swap station of the present application has good adaptability to battery packs of different sizes and different transfer mileage requirements, and can better meet the battery swap demand of the battery swap vehicle.

[0067] The places not described in the present application can be realized by using or referring to the existing technology.

[0068] Each embodiment in the present specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0069] The above merely provides an example of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the scope of claims of the present application.
