Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle battery replacement, and in particular to a battery replacement stacker and an application method. Background Art

[0002] With the substantial increase in the number of cars, environmental pollution is becoming increasingly serious. Pure electric vehicles are favored for their zero-emission and low-noise advantages. In order to save charging time, some electric vehicles currently use detachable on-board batteries for battery replacement and charging. When the vehicle is low on power, you only need to remove the low-power battery and replace it with a fully charged battery. The low-power battery is charged in the battery replacement station and then supplied to other electric vehicles. In this way, each electric vehicle only needs to spend the time of replacing the battery pack to restore power, without the need for charging waiting time, which greatly facilitates vehicle users.

[0003] At present, common battery swap stations are mainly composed of battery swap warehouses, charging warehouses, battery swap equipment and stackers. Stackers are extremely important as interactive equipment between charging warehouses and battery swap equipment. In the market, when stackers and battery swap equipment interact with battery packs, due to the shape and size of the battery or the overall size limitation, an intermediate interactive handover platform is set between the stacker and the battery swap equipment. This solution inevitably greatly reduces the speed of battery swapping and makes the battery swapping steps more complicated and cumbersome, causing certain troubles to the improvement of battery swapping efficiency and success rate. Therefore, the present application discloses a battery swapping stacker that can directly dock with battery swapping equipment without the need to use a traditional handover platform, thereby improving the speed of battery swapping.

[0006] Furthermore, the first lifting tray and the second lifting tray are both lifted vertically, and the orthographic projection of the first lifting tray on the horizontal plane is separated from the orthographic projection of the second lifting tray on the horizontal plane.

[0011] Furthermore, the tray frame is in the shape of an inverted "7", and the first lifting tray and the second lifting tray on both sides of the stacker frame are arranged opposite to each other.

[0012] Furthermore, the first sliding guide assembly and the first transmission assembly are both located on the inner side of the stacker frame.

[0047] The following specific implementations will further illustrate the present disclosure in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0048] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present disclosure, and the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0050] In each embodiment, for the convenience of description and not to limit the present disclosure, the term "connection" used in the patent specification and claims of the present disclosure is not limited to physical or mechanical connection, but may include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", etc. are only used to indicate relative position relationship. When the absolute position of the described object changes, the relative position relationship also changes accordingly.

[0051] like Figure 1 as well as Figure 2 As shown, the present invention seeks protection for a battery-swapping stacker, which is a structure adopting a double lifting device, specifically, including a stacker frame 1, and the stacker frame 1 is lifted and provided with a first lifting mechanism 2, the number of which is not less than two, and is located on both sides of the stacker frame 1. In the present embodiment, the number of the first lifting mechanism 2 is two, which are respectively located on the left and right sides of the stacker frame 1; the first lifting mechanism 2 includes a first lifting tray 201 and a tray frame 202, and the first lifting tray 201 is fixedly connected to the tray frame 202; a first sliding guide assembly 203 is connected between the stacker frame 1 and the tray frame 202, and the first sliding guide assembly 203 can be a combination of a slide rail and a slider, the slide rail is longitudinally connected to the stacker frame 1, and the slider is connected to the back of the tray frame 202 and cooperates with the slide rail, so that the tray frame 202 can slide up and down and be connected to the stacker frame 1; the first sliding guide assembly 203 is provided to guide the lifting and lowering of the first lifting mechanism 2 and to carry the deflection torque to ensure the lifting stability.

[0052] The pallet frame 202 is connected to a first transmission assembly 204, and the first transmission assembly 204 is connected to a first drive assembly 205. The first drive assembly 205 drives the first transmission assembly 204 to move. In the present embodiment, the first drive assembly 205 is a combination of a motor and a reduction gearbox. The first transmission assembly 204 is a chain drive, which is assembled on the stacker frame 1, and connects the first drive assembly 205 and the pallet frame 202, and converts the rotational motion of the motor in the first drive assembly 205 into the linear lifting motion required by the stacker, so as to realize the lifting and lowering of the pallet frame 202.

[0053] A second lifting mechanism 3 is arranged on the first lifting mechanism 2 for lifting; the second lifting mechanism 3 includes a second lifting tray 301, and the second lifting mechanism 3 also includes a second sliding guide assembly 302 connected between the tray frame 202 and the second lifting tray 301, and a second driving assembly 303 is arranged on the tray frame 202. In this structure, the structural forms of the second sliding guide assembly 302 and the second driving assembly 303 are the same as those in the first lifting mechanism 2, and are not described here; the second driving assembly 303 is connected to the second transmission assembly 304, and the second transmission assembly 304 is connected to the second lifting tray 301, and the second driving assembly 303 drives the second transmission assembly 304 to move, thereby driving the second lifting tray 301 to achieve lifting.

[0054] The first lifting tray 201 and the second lifting tray 301 are both lifted vertically, and the orthographic projection of the first lifting tray 201 on the horizontal plane is separated from the orthographic projection of the second lifting tray 301 on the horizontal plane, that is, when the second lifting tray 301 is lifted relative to the first lifting tray 201, there will be no interference between the two, which is conducive to the smooth lifting of the second lifting tray 301, and there will be no contact between the two to cause damage.

[0055] like Figures 3 to 14 As shown, an interactive station 4 is reserved between the first lifting mechanisms 2 on both sides. The interactive station 4 is helpful for the battery swapping equipment A and the battery swapping equipment B to enter and exchange the battery pack 10.

[0056] Since the battery swapping palletizer needs to exchange the battery pack 10 between the first lifting tray 201 and the second lifting tray 301, the second lifting tray 301 is set to rise to the highest position higher than the first lifting tray 201. At this time, the battery pack 10 will be lifted on the second lifting tray 301, so that the battery pack 10 will not come into contact with the first lifting tray 201 and affect the interaction; similarly, when the battery pack 10 needs to be exchanged to the first lifting tray 201, the second lifting tray 301 descends and is lower than the first lifting tray 201 when it is at the lowest position. At this time, the battery pack 10 will be transferred to the first lifting tray 201 and will not come into contact with the second lifting tray 301, so as to avoid affecting the interactive transfer. When the second lifting tray 301 is lifted relative to the first lifting tray 201, it is possible that the battery pack 10 is transferred from the second lifting tray 301 to the first lifting tray 201, or it is possible that the battery pack 10 is transferred from the first lifting tray 201 to the second lifting tray 301. The plane where the bearing surface on the second lifting tray 301 is located will overlap with the plane where the bearing surface on the first lifting tray 201 is located, that is, the bearing surfaces of the two will be at the same height, so that the battery pack 10 can be transferred smoothly between the first lifting tray 201 and the second lifting tray 301, and the stability is good.

[0057] By setting the distance between the first lifting trays 201 on the first lifting mechanisms 2 on both sides to be D 1 , set the distance between the second lifting trays 301 on the second lifting mechanisms 3 on both sides to be D 2 , then D 2 >D 1 , and also make the first lifting tray 201 and the second lifting tray 301 misaligned in the horizontal direction to avoid affecting the lifting of the second lifting tray 301.

[0058] In this embodiment, the second sliding guide assembly 302, the second transmission assembly 304 and the second lifting tray 301 are two groups, and the second driving assembly 303 is located between the two groups of second lifting trays 301; lifting the battery pack 10 by the two groups of second lifting trays 301 helps to improve stability, such as Figure 6As shown, the second drive assembly 303 is connected to the synchronous shaft 5 through a chain, and the two ends of the synchronous shaft 5 are respectively connected to the two groups of second transmission assemblies 304. The two ends of the synchronous shaft 5 and the second transmission assembly 304 are connected in a sprocket and chain manner, so that the two groups of second transmission assemblies 304 can be driven to move by one second drive assembly 303, thereby driving the corresponding second lifting tray 301 to rise and fall, making the structure compact and saving the cost of parts investment; and the second drive assembly 303 is located between the two groups of second lifting trays 301, so that the second drive assembly 303 avoids the second lifting tray 301, on the one hand, does not affect the lifting of the second lifting tray 301, and on the other hand, the second lifting tray 301 has enough descending space, so that when the battery pack 10 is transferred to the first lifting tray 201, it can be lowered below the first lifting tray 201.

[0059] The tray frame 202 is in the shape of an inverted "7", and the first lifting tray 201 and the second lifting tray 301 on both sides of the stacker frame 1 are relatively arranged, so that the battery pack 10 is transported by lifting the two sides, which helps to improve the stability of transportation.

[0060] from Figure 1 as well as Figure 2 It can be seen intuitively that the first sliding guide assembly 203 and the first transmission assembly 204 are both located on the inner side of the stacker frame 1. Since the first transmission assembly 204 will move during lifting, and the pallet frame 202 will also move through the first sliding guide assembly 203, by being arranged on the inner side, accidental contact by foreign objects or human limbs to create a safety hazard can be avoided.

[0061] like Fig.15 As shown, the present invention also claims a method for performing battery swap interaction using any of the above-mentioned battery swap stackers, comprising the following steps:

[0062] S1: Receive battery swap interaction request;

[0063] S2: The first lifting mechanism 2 takes a fully charged battery pack from the battery rack;

[0064] S3: The first lifting mechanism 2 exchanges the fully charged battery to the second lifting mechanism 3 and to the exchange station 4;

[0065] S4: Battery swapping device A enters interactive station 4;

[0066] S5: The second lifting mechanism 3 exchanges the fully charged battery to the battery swapping device A;

[0067] S6: Battery swap device A carries a fully charged battery into the battery swap warehouse;

[0068] S7: At the same time, the battery swapping device B enters the battery swapping compartment to remove the depleted battery, and then the battery swapping device A replaces it with a fully charged battery;

[0069] S8: Battery swap device B carries a low-power battery into interactive station 4;

[0070] S9: The second lifting mechanism 3 and the battery exchange device B interact to obtain the low-power battery;

[0071] S10: Both the battery swapping device A and the battery swapping device B avoid the interactive station 4;

[0072] S11: The second lifting mechanism 3 transfers the low-power battery to the first lifting mechanism 2;

[0073] S12: The first lifting mechanism 2 moves the low-power battery to the battery rack;

[0074] S13: The battery swap interaction ends.

[0075] The specific battery replacement method is: the high and low positions of the first lifting mechanism 2 are relative to the high and low positions of the stacker frame 1 , and the high and low positions of the second lifting mechanism 3 are relative to the high and low positions of the first lifting tray 201 on the first lifting mechanism 2 . At the beginning, the battery swapping equipment avoids the interactive station 4, the first lifting mechanism 2 is in a low position and the second lifting mechanism 3 is in a low position, the first lifting mechanism 2 rises and falls to find the fully charged battery pack 10, and the first lifting tray 201 obtains the fully charged battery pack 10 from the battery rack 6. At this time, the fully charged battery pack is located on the first lifting tray 201 of the first lifting mechanism 2, and returns to the interactive station 4. At the same time, the first lifting mechanism 2 descends to a low position and the second lifting mechanism 3 lifts to a high position, and the fully charged battery pack 10 is lifted by the second lifting tray 301 of the second lifting mechanism 3. At this time, the fully charged battery pack 10 is located on the second lifting tray 301 of the second lifting mechanism 3, and the battery swapping equipment enters the interactive station 4, the second lifting mechanism 3 descends to a low position, and the fully charged battery pack 10 is placed on the battery swapping equipment. This is the interactive process in which the stacker 9 obtains the fully charged battery pack 10 from the battery rack 6 and places it on the battery swapping equipment; at the beginning, the first lifting mechanism 2 The first lifting mechanism 2 is in a low position and the second lifting mechanism 3 is in a low position. The battery swapping equipment transports the deficient battery pack 10 into the interactive station 4. The first lifting mechanism 2 does not move and the second lifting mechanism 3 lifts to a high position, lifts the deficient battery pack 10 on the battery swapping equipment and detaches from the battery swapping equipment. At this time, the deficient battery pack is located on the second lifting tray 301 of the second lifting mechanism 3, and the battery swapping equipment leaves the interactive station 4. The first lifting mechanism 2 lifts and the second lifting mechanism 3 descends to a low position, and the deficient battery pack 10 falls onto the first lifting tray 201 of the first lifting mechanism 2. At the same time, the stacker 9 searches for an empty battery compartment of the battery rack 6, and the first lifting tray 201 puts the deficient battery pack into the empty battery compartment. This is the interactive process in which the stacker 9 obtains the deficient battery pack from the battery swapping equipment and puts it on the battery rack. Using dual battery swapping equipment (battery swapping equipment A and battery swapping equipment B) for interaction will greatly speed up the overall battery swapping interaction speed.
