Description

Technical Field

[0001] The present invention relates to the technical field of battery swapping stations, and particularly to a central lifting battery compartment and a battery swapping station. Background Art

[0002] Currently, in remote areas such as mining areas and forest areas, battery swapping stations are generally set up to solve the problem of battery charging for new energy operation vehicles. The battery swapping station mainly includes a battery compartment and a battery swapping robot. The battery compartment is mainly used to store the batteries to be replaced and is equipped with a charging cabinet to charge the batteries. Currently, the batteries in the battery compartment are arranged horizontally, and the heights of all the batteries are the same. Limited by the space of the site, the battery swapping robot is directly integrated on the top of the battery compartment and can move horizontally above the batteries.

[0003] During battery swapping, the operation vehicle to be swapped with a battery parks on one side of the battery compartment. The battery swapping robot moves to the position corresponding to the discharged battery, and then the telescopic arm extends to lift the discharged battery on the operation vehicle. At this time, the discharged battery needs to be lifted to a position higher than the batteries in the battery compartment to avoid interference between the discharged battery under the telescopic arm and the batteries in the battery compartment when the telescopic arm contracts; then, while the telescopic arm contracts, the battery swapping robot moves above the empty working station and unloads the discharged battery into the battery compartment for charging. At this time, the discharged battery is at the same height as the batteries in the battery compartment; finally, the battery swapping robot works in the reverse direction to move the fully charged battery inside the battery compartment to the operation vehicle.

[0004] Since the batteries of operation vehicles in areas such as mining areas and forest areas are relatively heavy, generally 3 - 8 tons, and the height of the batteries is relatively high, generally about 2 meters; from the above - mentioned battery swapping process, it can be seen that during the process of the battery swapping robot unloading the discharged battery and lifting the fully charged battery each time, the lifting stroke of the battery in the height direction must be greater than 2 meters. In addition, the lifting height of the battery is very slow, resulting in a long battery swapping time; moreover, due to the long lifting stroke of the battery, higher requirements are also put forward for the structural strength and operation accuracy of the battery swapping robot, thus driving up the cost of the battery swapping station. Summary of the Invention

[0005] The purpose of the present invention is to provide a central lifting battery compartment and a battery swapping station to reduce the lifting stroke of the battery during the battery swapping process, thereby shortening the battery swapping time and improving the battery swapping efficiency.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0008] The warehouse body has a central placement area and edge placement areas disposed on opposite sides of the central placement area, wherein the central placement area is located opposite to the battery on the working vehicle;

[0009] A lifting mechanism is disposed in the central placement area, the lifting mechanism can receive the battery and drive the battery to rise and fall in a vertical direction, the lifting mechanism can rise to a first height and can fall to a second height; and,

[0010] A raised platform is arranged in the edge placement area, the raised platform can position and receive the battery, and the height of the raised platform is greater than the second height.

[0011] Preferably, the lifting mechanism comprises:

[0012] chassis;

[0013] A lifting seat is slidably disposed on the base frame in a vertical direction, and the lifting seat can receive and position the battery; and

[0014] A driving assembly is arranged on the base frame, and the driving assembly is configured to drive the lifting seat to move up and down.

[0015] Preferably, the chassis comprises:

[0016] A set of columns is disposed on opposite sides of the lifting seat; and

[0017] The slide rail is arranged on a side of the column close to the lifting seat. The lifting seat is provided with a slider which is slidably connected to the slide rail.

[0018] Preferably, the chassis further comprises:

[0019] A bottom plate, disposed at the bottom end of the column; and

[0020] The reinforcing column is located at a side of the column away from the lifting seat, and the reinforcing column is connected between the bottom plate and the column.

[0021] Preferably, the lifting seat comprises:

[0022] Lifting beams, two of which are arranged at intervals;

[0023] a receiving plate, disposed between the two lifting beams, the receiving plate being capable of receiving the battery and positioning the battery; and

[0024] A positioning beam is arranged between the two lifting beams, and the positioning beam can receive the battery and position the battery.

[0025] Preferably, the bottom of the battery has a positioning groove and a positioning hole;

[0026] A first positioning post is vertically arranged on the receiving plate, the first positioning post can be inserted into the positioning groove, a second positioning post is vertically arranged on the positioning beam, the second positioning post is arranged lower than the first positioning post, and the second positioning post can be inserted into the positioning hole.

[0027] Preferably, a charging head is arranged on the chassis, the charging head is located at the bottom of the lifting seat, the position corresponding to the charging head on the lifting seat is hollowed out, and the charging head can be docked with the battery that has descended to the second height.

[0028] Preferably, a charging beam is arranged on the chassis, the charging head is located above the charging beam, and an elastic member is connected between the charging beam and the charging head.

[0029] Preferably, the central placement area and the edge placement area are distributed along a first direction, a plurality of the lifting mechanisms are arranged in the central placement area along a second direction perpendicular to the first direction, and a plurality of the heightening platforms are arranged in the edge placement area along the second direction.

[0030] A battery swapping station includes a central lifting battery bin and a battery swapping robot. The battery swapping robot is located inside the bin body and is arranged above the central placement area. The battery swapping robot can move along the distribution direction of the central placement area and the edge placement area.

[0031] Advantages of the present invention:

[0032] In the central lifting battery bin of the present invention, by arranging a lifting mechanism in the central placement area and a heightening platform in the edge placement area, the heightening platform directly raises the height of the battery in the edge placement area, and the lifting mechanism can drive the battery in the central placement area to lift or lower, so that the battery in the central placement area is lower than the battery in the edge placement area. The battery swapping robot carrying the battery at the bottom can lift the battery to a height higher than the battery in the central placement area and then enter the central placement area.

[0033] During battery swapping, if the depleted battery needs to be placed in the central placement area while the fully charged battery is located in the edge placement area, during the process of the battery swapping robot hoisting the depleted battery, the lifting mechanism can be synchronously raised to the first height to receive the battery. After the battery reaches above the lifting mechanism, the battery is unloaded onto the lifting mechanism, shortening the downward movement distance required during battery unloading, thus shortening the battery swapping time. Then, the battery swapping robot can continue to hoist the fully charged battery and drive the battery to descend to the second height through the lifting mechanism. Then, the battery swapping robot can directly hoist the battery on the raised platform, only needing to slightly lift the battery at a high position to be higher than the battery in the central placement area. The lifting distance of the battery is less than the height of the battery itself, thereby reducing the lifting distance required during battery hoisting and further shortening the battery swapping time and improving the efficiency of battery swapping. If the depleted battery needs to be placed in the edge placement area while the fully charged battery is located in the central placement area, then first unload the depleted battery onto the raised platform, and then hoist the battery from the lifting mechanism that has risen to the first height.

[0034] In addition, since the lifting distance of the battery is significantly shortened, the structural strength and operating precision of the battery swapping robot can be appropriately reduced, which can reduce the production cost of the battery swapping station.

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0045] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0047] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] The following will refer to Figures 1 to 7 to illustrate the central lifting battery compartment and the battery swapping station provided by the present invention.

[0049] Refer to Figure 1 and Figure 2 , the battery swapping station includes a central lifting battery compartment and a battery swapping robot 200. The interior of the central lifting battery compartment can store batteries 300. The battery swapping robot 200 is located inside the central lifting battery compartment. The battery swapping robot 200 can move in a first direction. The bottom of the battery swapping robot 200 has a telescopic arm, and the telescopic arm can telescopically extend in a second direction perpendicular to the first direction. The specific structure of the battery swapping robot 200 is the prior art and will not be elaborated here.

[0050] Furthermore, one side of the central lifting battery compartment is a parking area 100. The central lifting battery compartment and the parking area 100 are distributed along the second direction. The parking area 100 is for the operation vehicle to be battery-swapped to park at a fixed point. It can be understood that during battery swapping, when the operation vehicle is parked in the parking area 100, the telescopic arm extends in the second direction above the discharged battery 300 and hoists the discharged battery 300. Then the telescopic arm contracts inside the central lifting battery compartment. The battery swapping robot 200 moves above the vacant work station in the first direction, and then places the discharged battery 300 at the vacant work station inside the central lifting battery compartment for charging. Finally, the battery swapping robot 200 works in the reverse direction, moves the fully charged battery 300 to the operation vehicle, and completes the battery swapping operation.

[0051] Refer to Figure 2 , Figure 3 and Figure 4, the central lifting battery compartment includes a compartment body 1, a lifting mechanism 2, and a heightening platform 4. Inside the compartment body 1, there is a central placement area 13 and edge placement areas 14 disposed on opposite sides of the central placement area 13. The central placement area 13 is directly opposite the position of the discharged battery 300 on the work vehicle. The central placement area 13 and the edge placement areas 14 are distributed in a first direction. The lifting mechanism 2 is arranged in the central placement area 13. The lifting mechanism 2 can receive the battery 300 and drive the battery 300 to lift and lower in the vertical direction, so that the battery 300 can rise to a first height and can descend to a second height; the heightening platform 4 is arranged in the edge placement area 14. The heightening platform 4 can position and receive the battery 300, and the height of the battery 300 stored on the heightening platform 4 is greater than the second height.

[0052] Thus, during battery swapping, if the discharged battery 300 needs to be placed in the central placement area 13, that is, the vacant work station is in the central placement area 13 and the fully charged battery 300 is in the edge placement area 14; the telescopic arm of the battery swapping robot 200 extends from the central placement area 13 above the discharged battery 300 and hoists the discharged battery 300, and the lifting mechanism 2 synchronously rises to the first height. After the telescopic arm of the battery swapping robot 200 retracts above the lifting mechanism 2, the discharged battery 300 is directly unloaded onto the lifting mechanism 2 at the first height, shortening the downward movement distance required when unloading the discharged battery 300, thereby shortening the battery swapping time. Then, the battery swapping robot 200 moves above the fully charged battery 300, and the battery 300 is driven by the lifting mechanism 2 to descend to the second height; then, the battery swapping robot 200 directly hoists the fully charged battery 300 on the heightening platform 4. Since the heightening platform 4 is higher than the second height, the height ( Figure 4 H in it) that the battery 300 needs to be lifted here is less than the height of the battery 300, thereby reducing the lifting distance required when hoisting the battery 300 and further shortening the battery swapping time and improving the battery swapping efficiency.

[0053] In another case, that is, if the discharged battery 300 needs to be placed in the edge placement area 14 and the fully charged battery 300 is in the central placement area 13, then the discharged battery 300 is first unloaded onto the heightening platform 4, and the downward movement distance required when unloading the battery 300 ( Figure 4 H in it) is also shortened during this process. During the downward movement of the discharged battery 300, the lifting mechanism 2 synchronously rises to the first height to lift the fully charged battery 300 to the first height, reducing the lifting distance required when hoisting the battery 300, and similarly shortening the battery swapping time and improving the battery swapping efficiency.

[0054] In addition, it is worth noting that since the lifting distance of the battery 300 during battery swapping is significantly shortened, the structural strength and operating accuracy of the battery swapping robot 200 can be appropriately reduced, that is, the production cost of the battery swapping station can be reduced.

[0055] Preferably, along the first direction, each edge placement area 14 is provided with only one raised platform 4, and each raised platform 4 can only support one battery 300, that is, each edge placement area 14 is provided with only one battery 300, so as to prevent the battery replacement robot 200 carrying the battery 300 from moving inside the edge placement area 14 where the battery 300 is placed, and to prevent the interference between multiple batteries 300, thereby improving the convenience of battery replacement. Along the first direction, the central placement area 13 in this embodiment is provided with only one lifting mechanism 2, and each lifting mechanism 2 can only support one battery 300. Optionally, in some other embodiments, multiple lifting mechanisms 2 can also be provided in the central placement area 13 along the first direction.

[0056] Furthermore, since only one battery 300 is placed in the central placement area 13 and each edge placement area 14, the number of batteries 300 stored in the warehouse body 1 is small, which cannot meet the usage demand when there are many working vehicles. Figure 3 A plurality of lifting mechanisms 2 are arranged inside the central placement area 13 along the second direction, two of which are taken as an example in this embodiment, and a plurality of raising platforms 4 are arranged inside the edge placement area 14 along the second direction, two of which are taken as an example in this embodiment. The interior of the warehouse body 1 can store six batteries 300 in total, and five batteries 300 can be stored after removing one vacant station, so as to meet the battery replacement needs of multiple working vehicles.

[0057] Specifically, the warehouse body 1 includes a lower support frame 11 and a protective cover 12 connected to the upper part of the lower support frame 11. A through-compartment opening 15 is opened at the position of the warehouse body 1 corresponding to the central placement area 13, so that the telescopic arm can extend out of the warehouse body 1 through the through-compartment opening 15. At the same time, the part other than the through-compartment opening 15 provides better protection for the battery 300.

[0058] Reference Figure 3 and Figure 5 Further, each lifting mechanism 2 includes a base frame 21, a lifting seat 22 and a driving assembly 23. The lifting seat 22 is slidably arranged on the base frame 21 in the vertical direction, and the lifting seat 22 can receive and position the battery 300. The driving assembly 23 is arranged on the base frame 21, and the driving assembly 23 is configured to drive the lifting seat 22 to move up and down. The base frame 21 is used as the base of the lifting mechanism 2 to support and limit the lifting seat 22, and the driving assembly 23 drives the lifting seat 22 to move.

[0059] Reference Figure 5, Exemplarily, the chassis 21 includes a bottom plate 211, columns 212 and slide rails 2121. A set of columns 212 is provided on each of the opposite sides of the lifting seat 22. In this embodiment, the two sets of columns 212 are distributed in the first direction, and two columns 212 are provided in each set along the second direction. In other embodiments, three or more columns 212 may be provided in each set. The bottom plate 211 is connected to the bottom of each column 212, and the bottom plate 211 can be fixed to the ground by bolts to fix the column 212.

[0060] Further, a slide rail 2121 is connected to the side of each column 212 close to the lifting seat 22. The slide rail 2121 is vertically arranged, and a slider 2211 is slidably connected to each slide rail 2121. The slider 2211 is connected to the lifting seat 22. Thus, the lifting seat 22 is guided and limited through the cooperation of the slide rail 2121 and the slider 2211.

[0061] To enhance the structural strength of the chassis 21, cross beams 213 are connected to all the columns 212 in each set of columns 212. Two cross beams 213 are connected in the vertical direction. One cross beam 213 is located at the top of the column 212, and the other cross beam 213 is located at the bottom of the column 212, so as to form a stable frame structure between each set of columns 212 and the cross beam 213.

[0062] In addition, the chassis 21 further includes a strengthening column 214. The strengthening column 214 is located on the side of the column 212 facing away from the lifting seat 22, and the strengthening column 214 is connected between the bottom plate 211 and the column 212. The strengthening column 214 in this embodiment is vertically arranged. The bottom end of the strengthening column 214 is connected to the bottom plate 211, and the strengthening column 214 and the column 212 are connected by a plurality of horizontally arranged connecting columns 2141 to provide an auxiliary support effect on the column 212. A strengthening beam 2142 is connected between all the strengthening columns 214 of the lifting seat 22. Two strengthening beams 2142 are arranged in the vertical direction to further strengthen the strengthening column 214.

[0063] Optionally, in some other embodiments, the strengthening column 214 may also be inclined, and the top end of the strengthening column 214 is connected to the column 212, so as to form a triangle between the bottom plate 211, the strengthening column 214 and the column 212.

[0064] Refer to Figure 6, Further, the lifting seat 22 includes a lifting beam 221, a receiving plate 222, and a positioning beam 223. There are two lifting beams 221 arranged at intervals along the first direction. The lifting beams 221 are vertically arranged. The lifting beams 221 are square frames. The sliders 2211 are connected to the side of the lifting beams 221 close to the columns 212. The receiving plate 222 is connected between the two lifting beams 221. The receiving plate 222 can receive and position the battery 300. The positioning beam 223 is connected between the two lifting beams 221. The positioning beam 223 can receive and position the battery 300. In this embodiment, there are two receiving plates 222 and two positioning beams 223 arranged along the second direction. In some other embodiments, more receiving plates 222 and positioning beams 223 can also be provided. The lifting seat 22 with a frame structure is formed by the cooperation of the lifting beam 221, the receiving plate 222, and the positioning beam 223, which ensures its own structural strength while reducing weight, and maintains a certain contact area between the receiving plate 222 and the battery 300.

[0065] Exemplarily, one driving component 23 is provided corresponding to each group of columns 212 in this embodiment. Each driving component 23 includes a lead screw 231 and a driving member 232. The lead screw 231 is rotatably connected to the cross beam 213. A driving block 2212 is threadedly connected to the lead screw 231. The driving block 2212 is connected to the lifting beam 221. The driving member 232 is connected to the reinforcing beam 2142. The driving member 232 in this embodiment is a motor, and the motor is belt-driven with the lead screw 231. By simultaneously driving the two lead screws 231 to rotate by two motors, the driving block 2212 drives the lifting beam 221 to move up and down. In some other embodiments, the lifting beam 221 can also be driven to move up and down by components such as cylinders or electric cylinders.

[0066] Referring to Figure 6 and Figure 7 , Further, a charging beam 215 is connected to the chassis 21. Both ends of the charging beam 215 are connected to the reinforcing beam 2142. A charging head 3 is connected above the charging beam 215. The charging head 3 is connected to the power grid through a cable below. The position of the lifting seat 22 corresponding to the charging head 3 is hollowed out. When the lifting seat 22 descends to the second height, the charging head 3 is docked with the battery 300, thereby charging the battery 300. The charging head 3 is fixedly arranged on the chassis 21, so that the charging head 3 does not need to move up and down with the lifting seat 22, preventing the cable from getting fatigued.

[0067] In addition, an elastic member 31 is connected between the charging beam 215 and the charging head 3. The elastic member 31 in this embodiment is a spring as an example, so that there is a certain elastic margin between the charging head 3 and the charging beam 215 to make up for the deviation of the battery 300 and the charging head 3 in the height direction and the horizontal direction.

[0068] In order to position the battery 300 and make the battery 300 accurately dock with the charging head 3, the bottom of the battery 300 has a positioning groove and a positioning hole. One positioning groove is provided for each receiving plate 222, and two positioning holes are provided for each positioning beam 223. A first positioning column 2221 is vertically provided on the receiving plate 222, and the first positioning column 2221 can be inserted into the positioning groove. In this embodiment, four first positioning columns 2221 are connected to each receiving plate 222, and multiple first positioning columns 2221 are arranged along the circumference of the positioning groove. The top of each first positioning column 2221 has a guiding inclined surface 22211, so that the guiding inclined surface 22211 can guide and limit the battery 300.

[0069] Furthermore, two second positioning columns 2231 are vertically arranged on the positioning beam 223, and the second positioning columns 2231 are arranged lower than the first positioning columns 2221, and the second positioning columns 2231 can be inserted into the positioning holes. When the battery 300 is placed on the lifting seat 22, the battery 300 is first guided and limited by the higher first positioning columns 2221, i.e., roughly positioned, so that the second positioning columns 2231 can be accurately inserted into the positioning holes, and the battery 300 is precisely positioned by the second positioning columns 2231, so that the battery 300 is finally accurately docked with the charging head 3.

[0070] The heightened platform 4 in this embodiment is a frame structure formed by welding steel pipes, and a positioning plate having the same structure as the lifting seat 22 is also provided on the top thereof, and a charging head 3 is provided, so as to realize the receiving and accurate positioning of the battery 300. Optionally, in some other embodiments, the heightened platform 4 may be a flat plate or a support frame welded inside the warehouse body 1.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
