Description

Technical Field

[0001] The invention relates to a battery transport device, a battery replacement station or an energy storage station. Background Art

[0002] Quick-swap electric vehicles can meet the power supply needs of quick-swap electric vehicles by replacing batteries. During the battery replacement process, the battery to be charged needs to be removed from the electric vehicle and placed on a charging rack for charging, and the fully charged battery needs to be installed on the electric vehicle. The battery replacement process requires the use of battery transport equipment to transport the battery pack. Existing battery transport equipment usually transports batteries through an extension mechanism.

[0003] For example, a Chinese patent application with publication number CN211733721U discloses a battery transfer device for battery transfer, the battery transfer device comprising: a main frame, a battery lifting mechanism and a guide mechanism arranged in the main frame, the power batteries on both sides are taken and placed by moving the main frame along the extension direction of the guide mechanism and the battery lifting mechanism which can be lifted and lowered, the battery lifting mechanism comprising a bidirectional telescopic mechanism which can be extended or retracted to both sides and is used to take out or place the corresponding power battery, when the bidirectional telescopic mechanism takes the power battery back to the cavity of the main frame from the outside, the position of the power battery relative to the frame structure is detected by a position sensor to ensure that the power battery can be aligned with the position of the frame structure, thereby ensuring that the placement stability of the power battery can reach the best, therefore, ensuring the stability of the power battery in the transfer on the battery support platform for installing the bidirectional telescopic mechanism, so as to avoid the power battery from slipping off the battery support platform and causing damage to the power battery.

[0004] However, the above-mentioned prior art still has the following defects: when the battery transport device transports the battery, the battery position may be easily offset or skewed due to slippage between the battery and the extension mechanism or impact by external force during the movement process, that is, the horizontal direction of the battery forms an angle with the direction of entry and exit of the battery, which may easily cause the battery to fail to connect correctly with the electrical connector after entering. Therefore, the prior art lacks a technical solution for adjusting the position of the battery before entering. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the problem in the prior art that the battery position is skewed and cannot be accurately moved into the battery compartment and accurately connected to the electrical connector due to the slippage between the battery pack and the extension mechanism during battery transportation, as well as the defect of installing a battery positioning device in the battery compartment, which is cumbersome to install and occupies space in the compartment, and to provide a battery transportation equipment, battery swap station or energy storage station.

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

[0007] A battery transfer device comprises an outer frame, an extension mechanism arranged in the outer frame and used for taking and placing a battery pack from a battery compartment, and a battery position adjustment device for adjusting the position of the battery pack on the battery transfer device. The battery position adjustment device is connected to the outer frame or the extension mechanism and is used for adjusting the position of the battery pack carried on the extension mechanism.

[0008] This solution achieves position adjustment of the battery during battery transportation or after the battery is retracted into the outer frame by setting a battery position adjustment device on the outer frame or the extension mechanism of the battery transportation equipment. The battery pack position is corrected to maintain the optimal position, thereby ensuring that the battery pack can be accurately delivered to the battery compartment, thereby improving the battery transportation efficiency. In addition, compared with setting a battery positioning device in each battery compartment, it avoids occupying space in the battery compartment, reduces installation costs, and has a simple and reliable structure.

[0009] Preferably, the extension mechanism comprises a base fixed on the outer frame and an extension member movably connected to the base.

[0010] The battery position adjustment device comprises:

[0011] An adjusting member disposed at both ends of the base along the extension direction of the extending mechanism, for adjusting the battery pack by driving the adjusting member to rotate from the plane direction of the battery pack to the height direction of the battery pack so as to contact with both sides of the battery pack after the extending member carries the battery pack and retracts into place; or

[0012] At least two adjustment members are arranged at both ends of the extending member along the extension direction of the extending mechanism. The adjustment members extend and retract synchronously with the extending member. After the extending member carries the battery pack, the adjustment members are driven to rotate from the plane direction of the battery pack to the height direction of the battery pack so as to interfere with the two sides of the battery pack to adjust the battery pack.

[0013] The adjusting member is arranged on the base and does not extend together with the extending member, so that it rises when the extending mechanism is retracted to adjust the position of the battery pack, and when the extending mechanism is extended, the adjusting member needs to be lowered to avoid blocking the movement of the battery pack in the extending direction of the extending mechanism. The adjusting member thus arranged is connected to the base, which reduces the weight of the extending mechanism.

[0014] The adjusting part is arranged on the extending part so that it moves synchronously with the extending part; during the extension and retraction process of the extending mechanism, the adjusting part can adjust the position of the battery pack at any time. The best situation is to adjust the position of the battery pack immediately when the extending part obtains the battery pack, and maintain the position of the battery pack during the extension and retraction process to ensure that the battery pack is always in the optimal position, thereby reducing the adjustment time before the extension and retraction of the extending mechanism and improving the adjustment efficiency of the adjusting part.

[0015] Preferably, the number of the extending mechanisms is two, and the adjusting members are respectively arranged at two ends of the two extending mechanisms, and / or the extending mechanism is a bidirectional extending mechanism.

[0016] Thus, the adjusting member can be adjusted from both sides of the battery pack simultaneously along the extension direction, thereby improving the adjustment efficiency. The extension mechanism can also be a one-way extension mechanism or a two-way extension mechanism, both of which can be adjusted by the adjusting member.

[0017] Preferably, the extending member includes a primary extending unit movably connected to the base and a secondary extending unit movably connected to the primary extending unit, and the adjusting member is arranged on the base or the secondary extending unit.

[0018] The adjusting member moves together with the secondary extension unit, ensuring synchronous movement between the adjusting member and the battery pack, thereby avoiding interference of the adjusting member with the movement of the battery pack.

[0019] Preferably, the battery position adjustment device includes at least one adjustment member arranged at each end of the outer frame along the extension direction of the extending mechanism, and is used to adjust the battery pack by driving the two adjustment members to rotate from the plane direction of the battery pack to the height direction of the battery pack after the extending mechanism carries the battery pack and retracts into position so as to interfere with both sides of the battery pack.

[0020] The adjustment member is arranged on the outer frame and does not extend together with the extension member, so that when the extension mechanism is retracted, the adjustment member is controlled to rise so as to adjust the position of the battery pack, and when the extension mechanism is extended, the adjustment member is controlled to fall to avoid hindering the movement of the battery pack in the extension direction of the extension mechanism. The adjustment member thus arranged is located on the outer frame, which reduces the weight of the extension mechanism. In addition, there are few relatively moving structures on the outer frame, which facilitates the installation of the adjustment member.

[0021] Preferably, at least two adjusting members are disposed at each end along the extension direction of the extending mechanism, and the adjusting members located on the same side of the extending mechanism are disposed at intervals.

[0022] Therefore, along the extension direction of the extending mechanism, at least two adjustment members are respectively provided on both sides of the battery pack for position adjustment, which can improve the efficiency of position adjustment on the one hand, and can also improve the stability of the battery during the adjustment process on the other hand.

[0023] Preferably, the adjusting member has a push surface on a side surface facing the battery pack, and the push surface is inclined from top to bottom along the height direction of the battery pack in a direction gradually approaching the battery pack.

[0024] Therefore, if the battery pack is offset, the surface of the battery pack can move naturally along the push surface, and finally be limited to the correct posture at the closest distance to the inclined guide surface, thereby ensuring the position adjustment effect.

[0025] Preferably, the battery transporting device further comprises a driving mechanism for driving the adjusting member to rotate.

[0026] The automatic lifting and lowering adjustment part is realized through the driving mechanism, thereby improving the efficiency of position adjustment; and the rotating setting can reduce the space occupied, the driving is simple, and the adjustment reliability is high.

[0027] Preferably, the driving mechanism comprises a traction line and a wire winding portion, the traction line is connected to the adjusting member, and the wire winding portion reels in or releases the traction line to drive the rotation of the adjusting member.

[0028] The traction line can reduce the difficulty of layout, and at the same time, there is no need to set up additional space for fixing the transmission mechanism in a limited space, so the narrow space can be fully utilized.

[0029] Preferably, the position adjustment device further comprises a synchronization shaft which is arranged along the extension direction of the extending mechanism and connects the two corresponding adjustment members, and the rotation of the synchronization shaft drives the two corresponding adjustment members to rotate synchronously.

[0030] The rotation direction of the adjusting member can be limited by the synchronizing shaft, ensuring that the adjusting member can be raised according to a predetermined trajectory and ensuring that the adjusting members on both sides move synchronously, thereby improving the adjustment efficiency and accuracy.

[0031] Preferably, the position adjustment device further comprises a plurality of reset members, and the reset members are connected to the adjustment members or the synchronization shafts one by one for driving the corresponding adjustment members to return to their initial positions.

[0032] The restoring force provided by the reset member can enable the adjustment member to return to its initial state, that is, the lowered state, after the driving mechanism stops applying force, thereby avoiding interference with the movement of the battery pack.

[0033] Preferably, the two adjusting members are respectively arranged on the inner sides of the extending mechanisms, and the adjusting members are respectively raised and lowered from the inner sides of the two extending mechanisms.

[0034] The adjustment parts are all located on the inner side of the extending mechanism, which can avoid increasing the lateral width of the original battery transfer equipment structure and make the structure more compact.

[0035] Preferably, when the adjusting member is in the initial position, the top surface of the adjusting member is arranged to be no higher than the battery bearing surface of the extending mechanism.

[0036] This arrangement ensures that the adjustment member will not interfere with the entry and exit of the battery pack in the initial state, nor will it affect the normal operation of the extension mechanism.

[0037] A battery swap station or an energy storage station, wherein the battery swap station or the energy storage station comprises the battery transfer equipment.

[0038] The positive progressive effect of the present invention is that: the present invention arranges a battery position adjustment device on the outer frame or the extension mechanism of the battery transfer equipment, thereby achieving position adjustment of the battery during the battery transfer process or after the battery is retracted into the outer frame, and corrects the position of the battery pack to keep it in the optimal position, thereby ensuring that the battery pack can be accurately delivered to the battery compartment, thereby improving the battery transfer efficiency; in addition, compared with setting a battery positioning device in each battery compartment, it avoids occupying space in the battery compartment, reduces installation costs, and has a simple and reliable structure.

[0048] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0049] Example 1

[0050] like Figure 1-Figure 7 As shown, this embodiment discloses a battery transport device, which can be used in a battery swap station or an energy storage station. Figure 1-Figure 3 As shown, the battery transport device of this embodiment includes an outer frame 1, an extension mechanism 2 disposed in the outer frame 1 and used for taking and placing a battery pack 7 from a battery compartment, and a battery position adjustment device 3 for adjusting the position of the battery pack 7 on the battery transport device. The battery position adjustment device 3 is connected to the extension mechanism 2 and is used to adjust the position of the battery pack 7 carried on the extension mechanism 2. In this embodiment, by arranging the battery position adjustment device 3 on the outer frame 1 or the extension mechanism 2 of the battery transport device, the position of the battery pack 7 is adjusted during the battery transport process or after the battery is retracted into the outer frame 1. By correcting the position of the battery pack 7 to keep it in the best position, it is ensured that the battery pack 7 can be accurately delivered into the battery compartment, thereby improving the battery transport efficiency. In addition, compared with arranging a battery positioning device in each battery compartment, it avoids occupying the space in the battery compartment, reduces the installation cost, and has a simple and reliable structure.

[0051] like Figure 1-Figure 3 As shown, the extension mechanism 2 of this embodiment includes a base 11 fixed on the outer frame 1, and an extension member 20 movably connected to the base 11. The battery position adjustment device 3 includes adjustment members 31 arranged at both ends of the extension member 20 along the extension direction of the extension mechanism 2, as shown in FIG. Figure 4 and Figure 5 As shown, the adjustment member 31 moves synchronously with the extension member 20, and is used to adjust the battery pack 7 by driving the adjustment member 31 to rotate from the plane direction of the battery pack 7 to the height direction of the battery pack 7 after the extension member 20 carries the battery pack 7, thereby interfering with the two sides of the battery pack 7. In this embodiment, since the adjustment member 31 is provided on the extension member 20, it moves synchronously with the extension member 20. During the extension and retraction of the extension mechanism 2, the adjustment member 31 can adjust the position of the battery pack at any time. The best practice is to adjust the position of the battery pack 7 immediately when the extension member 20 obtains the battery pack 7, and to maintain the position of the battery pack 7 during the extension and retraction process, to ensure that the battery pack 7 is always in the best position, thereby reducing the adjustment time before the extension and retraction of the extension mechanism 2 and improving the adjustment efficiency of the adjustment member 31. Figure 7 As shown, in a preferred implementation state, when the extending mechanism 2 is just extended, the adjusting member 31 extends to align the battery pack 7, and then completes the descent before the extending mechanism 2 is extended into place.

[0052] like Figure 1-Figure 3 As shown, in a preferred embodiment, there are two extension mechanisms 2, which are arranged along the extension direction perpendicular to the extension mechanism 2, and four adjustment members 31 are respectively arranged at both ends of the two extension mechanisms 2. The four adjustment members 31 can be adjusted from both sides of the battery pack along the extension direction to improve the adjustment efficiency. In this embodiment, the type of the extension mechanism 2 can be a one-way extension mechanism or a two-way extension mechanism 2, and both can be adjusted by the adjustment member 31.

[0053] Of course, in some other optional embodiments, the number of the extension mechanisms 2 may be one, or more than two. In some other embodiments, the number of the adjustment members 31 may be any number, and some extension mechanisms 2 may not be connected to the adjustment members 31. For example, in the case of three extension mechanisms 2, the adjustment members 31 may be provided only on two of the extension mechanisms 2. In some other embodiments, the adjustment members 31 connected to each extension mechanism 2 may also be adjusted according to actual conditions. For example, some extension mechanisms 2 are provided with an adjustment member 31 on the side facing the battery compartment, but not on the side facing away from the battery compartment; other extension mechanisms 2 are provided with an adjustment member 31 on the side facing away from the battery compartment, but not on the side facing the battery compartment.

[0054] like Figure 1-Figure 3 As shown, in a preferred embodiment, the extension member 20 of the extension mechanism 2 includes a primary extension unit 201 movably connected to the base 11 and a secondary extension unit 202 movably connected to the primary extension unit 201, and the adjustment member 31 is disposed on the secondary extension unit 202. The adjustment member 31 moves with the secondary extension unit 202, ensuring that the adjustment member 31 and the battery pack 7 move synchronously, thereby avoiding interference of the adjustment member 31 with the movement of the battery pack 7.

[0055] like Figure 1-Figure 3 As shown, in a preferred embodiment, two adjustment members 31 are respectively provided at both ends along the extension direction of the extending mechanism 2, and the adjustment members 31 located on the same side of the extending mechanism 2 are provided at intervals. Thus, along the extension direction of the extending mechanism 2, at least two adjustment members 31 are respectively provided on both sides of the battery pack 7 for position adjustment, which improves the efficiency of position adjustment on the one hand, and can also improve the stability of the battery during the adjustment process on the other hand. In some other optional embodiments, only one adjustment member 31 may be provided at each end along the extension direction of the extending mechanism 2, or more than two adjustment members may be provided. In other optional embodiments, the number of adjustment members 31 at both ends of the extension direction of the extending mechanism 2 may be inconsistent, and the positions may not correspond to each other, and they may be staggered along the extension direction perpendicular to the extending mechanism 2.

[0056] like Figure 3 and Figure 7As shown, in a preferred embodiment, the adjustment members 31 are respectively arranged on the inner sides of the two extending mechanisms 2, and the adjustment members 31 are respectively raised and lowered from the inner sides of the two extending mechanisms 2. The adjustment members 31 are all located on the inner sides of the extending mechanisms 2, which can avoid increasing the lateral width of the structure of the original battery transport device, making the structure more compact. In other embodiments, the adjustment members 31 can also be arranged on the outer sides of the extending mechanisms 2, or a part of the adjustment members 31 is arranged on the inner side of the extending mechanisms 2, and the other part is arranged on the outer side of the extending mechanisms 2.

[0057] like Figure 4 and Figure 5 As shown, in a preferred embodiment, when the adjusting member 31 is in the initial position, the top surface of the adjusting member 31 is set to be no higher than the battery bearing surface of the extending mechanism 2. This arrangement ensures that the adjusting member 31 will not interfere with the entry and exit of the battery pack 7 in the initial state, will not lift the battery pack 7, and will not affect the normal operation of the extending mechanism 2.

[0058] like Figure 6 As shown, in a preferred embodiment, the side of the adjustment member 31 facing the battery pack 7 has a push surface 311, and the push surface 311 is inclined from top to bottom along the height direction of the battery pack 7 in a direction gradually approaching the battery pack 7. Therefore, if the battery pack 7 is offset, the surface of the battery pack 7 can naturally move along the push surface 311, and finally be limited to the correct posture at the closest distance to the inclined guide surface to ensure the position adjustment effect. In some other embodiments, the side of the adjustment member 31 facing the battery pack 7 can also be other types of surfaces with gradually narrowing guiding functions, such as various forms such as curved surfaces, inclined surfaces, and combinations of curved surfaces and inclined surfaces. In some other embodiments, the adjustment members 31 located at both ends of the extension direction of the extension mechanism 2 can be set to move closer to each other, and at this time, the side of the extension mechanism 2 facing the battery pack 7 can be a plane.

[0059] like Figure 1-Figure 3 As shown, in a preferred embodiment, the position adjustment device also includes a synchronization shaft 32 arranged along the extension direction of the extension mechanism 2 and connected to the corresponding two adjustment members 31. The rotation of the synchronization shaft 32 drives the corresponding two adjustment members 31 to rotate synchronously. The rotation direction of the adjustment member 31 can be limited by the synchronization shaft 32 to ensure that the adjustment member 31 can be raised according to a predetermined trajectory. The synchronization shaft 32 can also ensure that the adjustment members 31 on both sides move synchronously, thereby improving the adjustment efficiency and accuracy.

[0060] Of course, in some optional embodiments, the adjustment members 31 arranged along the extension direction of the extension mechanism 2 may not have any connection relationship and rotate independently. Alternatively, in some other optional embodiments, the adjustment members 31 arranged along the extension direction of the extension mechanism 2 may also be connected through other transmission structures, such as gears, sprockets or pulleys.

[0061] In a preferred embodiment, the battery transport device further comprises a driving mechanism for driving the rotation of the adjusting member 31. The driving mechanism realizes automatic lifting and lowering of the adjusting member 31, improves the efficiency of position adjustment, and the rotation setting can reduce the space occupied, the driving is simple, and the adjustment reliability is high.

[0062] like Figure 2 and Figure 6 As shown, in a further preferred embodiment, the driving mechanism includes a traction line 5 and a winding part 4, the traction line 5 is connected to the adjusting member 31, and the winding part 4 retracts or releases the traction line 5 by rotating itself, and each end of the traction line 5 moves accordingly, thereby driving the rotation of the adjusting member 31 connected to each end of the traction line 5. Figure 6 The example in the figure shows the connection between one of the adjustment members 31 and the traction line 5, and the other adjustment members 31 can be connected by the same means. The traction line 5 can reduce the difficulty of layout, and at the same time, there is no need to set up additional space for fixing the transmission mechanism in a limited space, so that the narrow space can be fully utilized.

[0063] Of course, in some optional embodiments, the driving mechanism may also use other transmission devices, such as a motor, a cylinder or other power device to directly or indirectly drive the rotation of the adjustment member 31. Among them, various structures such as belts, gears, connecting rods, etc. can be used to connect the power device and the adjustment member 31, and drive the adjustment member 31 to rotate.

[0064] like Figure 6 As shown, in a further preferred embodiment, the wire winding portion 4 is connected to the crossbeam 6. One end or both ends of the crossbeam 6 are connected to the extension member 20 of the extension mechanism 2 on one side or both sides, so as to ensure that the wire winding portion 4 is extended together. At the same time, the traction line 5 extends along the crossbeam 6, and the crossbeam 6 provides an extension support for the traction line 5 to prevent the traction line 5 from falling and being rolled into other motion mechanisms.

[0065] like Figure 6As shown, in a further preferred embodiment, the position adjustment device further includes a plurality of reset members 33, and the reset members 33 are connected to the adjustment members 31 or the synchronization shafts 32 one by one, and are used to drive the corresponding adjustment members 31 to return to the initial position. The restoring force provided by the reset members 33 can enable the adjustment members 31 to return to the initial state of the initial position, that is, the lowered state, after the driving mechanism stops applying force, so as to avoid interference with the movement of the battery pack 7. Among them, one may be that when the driving mechanism is not in operation, the reset member 33 causes the adjustment member 31 to rise, and when the driving mechanism is in operation, the driving mechanism overcomes the restoring force of the reset member 33 to cause the adjustment member 31 to fall. Another may be that when the driving mechanism is not in operation, the reset member 33 causes the adjustment member 31 to fall, and when the driving mechanism is in operation, the driving mechanism overcomes the restoring force of the reset member 33 to cause the adjustment member 31 to rise. The reset member 33 may be one or more of various elastic members such as torsion springs, springs, and coil springs.

[0066] Of course, in other embodiments, when the driving mechanism can perform forward and reverse movement, the raising and lowering of the adjusting member 31 can be achieved through the driving mechanism itself, so normal operation can be achieved without providing a reset member.

[0067] Example 2

[0068] like Figure 8 As shown, the battery transfer equipment of this embodiment is different from that of embodiment 1 in that the battery position adjustment device 3 of this embodiment is arranged on the base 11, including adjustment members 31 arranged at both ends of the base 11 along the extension direction of the extension mechanism 2, which is used for adjusting the battery pack 7 by driving the adjustment member 31 to rotate from the plane direction of the battery pack 7 to the height direction of the battery pack 7 after the extension member 20 carries the battery pack 7 and retracts into place, thereby interfering with the two sides of the battery pack 7.

[0069] The adjusting member 31 of this embodiment is arranged on the base 11, and is not extended together with the extending member 20, so that it rises when the extending mechanism 2 is retracted to adjust the position of the battery pack 7, and when the extending mechanism is extended, the adjusting member 31 needs to be lowered to avoid blocking the movement of the battery pack 7 in the extending direction of the extending mechanism 2. The adjusting member 31 thus arranged is connected to the base 11, reducing the weight of the extending mechanism.

[0070] Except for the difference in the setting position of the battery position adjusting device 3, the battery transporting equipment of this embodiment can also adopt the preferred embodiment and optional embodiment of the embodiment, which will not be elaborated here.

[0071] Example 3

[0072] like Fig. 9As shown, the battery transport device of this embodiment is different from that of the first embodiment in that the battery position adjustment device 3 of this embodiment is arranged on the outer frame 1, and is different from that of the second embodiment in that the battery position adjustment device 3 of this embodiment is directly arranged on the outer frame 1, rather than being indirectly connected to the outer frame 1 through the base 11. The battery position adjustment device 3 of this embodiment includes at least one adjustment member 31 arranged at each end of the outer frame 1 along the extension direction of the extension mechanism 2, which is used to adjust the battery pack 7 by driving the two adjustment members 31 to rotate from the plane direction of the battery pack 7 to the height direction of the battery pack 7 after the extension mechanism 2 carries the battery pack 7 and retracts to its position, so as to contact with the two sides of the battery pack 7.

[0073] The adjustment member 31 of this embodiment is arranged on the outer frame 1, and is not extended together with the extension member 20, so that when the extension mechanism 2 is retracted, the adjustment member 31 is controlled to rise so as to adjust the position of the battery pack 7, and when the extension mechanism is extended, the adjustment member 31 is controlled to fall to avoid hindering the movement of the battery pack 7 in the extension direction of the extension mechanism 2. The adjustment member 31 thus arranged is located on the outer frame 1, which reduces the weight of the extension mechanism. In addition, there are few relatively moving structures on the outer frame 1, which facilitates the installation of the adjustment member 31.

[0074] Except for the difference in the setting position of the battery position adjusting device 3, the battery transporting equipment of this embodiment can also adopt the preferred embodiment and optional embodiment of the embodiment, which will not be elaborated here.

[0075] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
