Description

Technical Field

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

[0002] Currently, in remote areas such as mining areas and forest areas, battery swapping stations are generally used to solve the problem of recharging electric operation vehicles (such as mining trucks). Referring to Figure 1 , the existing battery swapping station includes a battery bin 1, a battery swapping platform 300, a robot frame, and a battery swapping robot 2. The battery bin 1 is located on one side of the battery swapping platform 300 and is used to store batteries 200 and charge the batteries 200. The robot frame is arranged on the battery swapping platform 300, and the battery swapping robot 2 is arranged on the robot frame.

[0003] During battery swapping, the operation vehicle for battery swapping is parked on the side of the battery swapping platform 300 away from the battery bin 1. After the battery swapping robot 2 moves along the ground rail on the battery swapping platform 300 to an approximate position, the telescopic arm of the battery swapping robot 2 extends forward to align the lifting device with the battery 200, and the discharged battery 200 is lifted; then the battery swapping robot 2 moves to the vacant working position in the battery bin 1, the telescopic arm extends backward, and the discharged battery 200 is unloaded into the battery bin 1 for charging; finally, the battery swapping robot 2 works in reverse to move the fully charged battery 200 inside the battery bin 1 to the operation vehicle.

[0004] Since the batteries 200 of the operation vehicles in areas such as mining areas and forest areas are relatively heavy, generally 3 - 8 tons, and the battery swapping robot 2 uses the self - weight of the robot frame as a counterweight, the extension length of the telescopic arm is limited. Otherwise, the telescopic arm is prone to bending deformation, and even the battery swapping robot 2 may tip over. Therefore, the batteries 200 inside the current battery bin 1 can only be arranged in a row along the moving direction of the battery swapping robot 2 (the length direction of the battery swapping platform 300).

[0005] Combined with the above - mentioned battery swapping process, since the batteries inside the battery bin are arranged along the moving direction of the battery swapping robot, when the vacant working position is close to the end of the battery bin, the battery swapping robot needs to walk a relatively long distance to unload the discharged battery, and when the fully charged battery is close to the end of the battery bin, the battery swapping robot needs to walk a relatively long distance to grab the fully charged battery; moreover, due to the large self - weight of the robot frame, the moving speed of the battery swapping robot is extremely slow, ultimately resulting in a slow battery swapping speed and greatly affecting the battery swapping efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a battery swapping station system to reduce the moving distance of the battery swapping robot, accelerate the battery swapping speed of the operation vehicle, and improve the battery swapping efficiency.

During the battery replacement process, the travel distance that the battery replacement robot needs to move along the first horizontal direction is greatly shortened, thereby shortening the battery replacement time; when the number of batteries in the battery compartment is the same, the batteries are arranged in multiple rows, which can reduce the distance between some batteries and the parking area in the second horizontal direction, thereby further shortening the travel distance that the battery replacement robot needs to move during the battery replacement process, thereby further improving the battery replacement efficiency;

[0035] 2. Reduce the floor area: By removing the original battery swapping platform, the space occupied by the original battery swapping platform is released, which can improve the adaptability of the battery swapping station system to the installation space;

[0036] 3. Reduce the production cost: There is no need to manufacture the battery swapping platform, and the complex and heavy self-weight robot frame is replaced by the support frame inside the battery compartment, thus achieving a reduction in production cost;

[0037] 4. Improve the reliability of battery swapping: The battery swapping robot is integrated inside the battery compartment and connected to the support frame, so that the entire battery compartment serves as the base and counterweight of the battery swapping robot, making the battery swapping robot more stable during operation and improving the reliability of the battery swapping robot's work.

[0058] The following refers to Figures 1 to 10 to describe the battery swapping station system provided by the present invention.

[0059] The battery swapping station system is designed to swap the batteries of power-deficient operation vehicles and solve the defects of the existing battery swapping stations, such as large volume, complex structure, low efficiency, high cost, and difficult transportation. Thus, the battery swapping station system achieves beneficial effects such as small footprint, high stability, low cost, high efficiency, and convenient transportation and installation. One side of the battery swapping station system has a parking area 100 for operation vehicles to park. For the specific structure of the battery swapping station system, please refer to the following content of this embodiment.

[0060] Refer to Figure 2 、 Figure 3 and Figure 4 , the battery swapping station system includes a battery bin 1 and a battery swapping robot 2. The battery bin 1 and the parking area 100 are distributed along a first horizontal direction. Inside the battery bin 1, at least two rows of placement positions 13 for placing batteries 200 are arranged along the first horizontal direction. Each row of placement positions 13 is distributed along a second horizontal direction perpendicular to the first horizontal direction. At least one placement position 13 in the battery bin 1 is in an empty state. The battery swapping robot 2 is connected inside the battery bin 1 and is configured to hoist the battery 200 in the parking area 100 to any placement position 13 and hoist the battery 200 stored in any placement position 13 to the parking area 100.

[0061] As above, the placement positions 13 inside the battery bin 1 are arranged in multiple rows, and the battery swapping robot 2 is arranged inside the battery bin 1, that is, the battery swapping robot 2 is directly placed above the battery 200, thus canceling the original battery swapping platform and robot frame. First, the distance between the row of placement positions 13 close to the parking area 100 in the first horizontal direction can be reduced, thereby shortening the travel distance that the battery swapping robot 2 needs to move in the first horizontal direction, shortening the battery swapping time, and improving the battery swapping efficiency.

[0062] Secondly, when the number of batteries 200 inside the battery bin 1 is the same, the distance between some batteries 200 and the parking area 100 can be reduced in the second horizontal direction, thereby greatly shortening the travel distance that the battery swapping robot 2 needs to move during the battery swapping process, shortening the battery swapping time, realizing the improvement of the battery swapping efficiency, and at the same time, the shortening of the travel distance also improves the safety of the operation.

[0063] For example, the present embodiment is described by comparing the arrangement of six placement positions 13 inside the battery compartment 1. The original six placement positions 13 are arranged along the second horizontal direction (refer to Figure 1 ), the length of each placement position 13 along the second horizontal direction is L, and the parking area 100 is located at the center of the battery compartment 1 along the second horizontal direction. In the second horizontal direction, the distance between the placement position 13 farthest from the parking area 100 and the parking area 100 is approximately 3L. If this placement position 13 is an empty placement position 13 or a placement position 13 storing a fully charged battery 200, the battery swap robot 2 needs to move a distance of 3L along the second horizontal direction. Figure 3 , and the six placement positions 13 in this embodiment are divided into two rows, with three placement positions 13 in each row. In the first horizontal direction, the distance between the two rows of placement positions 13 is compensated by the movement of the battery-swapping robot 2. In the second horizontal direction, the distance between the placement positions 13 on both sides and the parking area 100 is approximately L, that is, the battery-swapping robot 2 can unload and hoist the battery 200 by moving a distance of L along the second horizontal direction, thereby reducing the travel distance that the battery-swapping robot 2 needs to move in the second horizontal direction. By superimposing the shortened travel distance of the battery-swapping robot 2 in the first horizontal direction, the battery-swapping time can be shortened by half, further improving the battery-swapping efficiency. Of course, in some other embodiments, the placement positions 13 can also be set to eight or more. This embodiment only takes six placement positions 13 as an example for illustration.

[0064] In addition, the removal of the battery swap platform and robot frame frees up the space occupied by the original battery swap platform, reducing the footprint of the battery swap station system. At the same time, the costs associated with manufacturing, transporting and assembling the battery swap platform and robot frame are eliminated, reducing production costs.

[0065] Finally, the battery-swapping robot 2 is integrated inside the battery compartment 1, so that the entire battery compartment 1 serves as the base and counterweight of the battery-swapping robot 2, making the battery-swapping robot 2 more stable during operation and improving the reliability of the battery-swapping robot 2.

[0066] Reference Figure 5 and Figure 6 Specifically, the battery compartment 1 includes a main compartment body 11 and a side compartment body 12. The main compartment body 11 is provided with a compartment opening 113 at a position corresponding to the parking area 100. The side compartment body 12 is provided on the side of the main compartment body 11 away from the parking area 100. The side of the side compartment body 12 close to the main compartment body 11 is connected to the main compartment body 11, and a row of placement positions 13 (three placement positions 13) are provided inside the main compartment body 11 and inside the side compartment body 12. The main compartment body 11 and the side compartment body 12 are combined to form the battery compartment 1, so that the manufacture, transportation and installation of the battery compartment 1 are more convenient, and they can also be replaced separately later to reduce production costs and later use costs.

[0067] Furthermore, the main warehouse body 11 includes a lower support frame 111 and an upper protective cover 112. The upper protective cover 112 is connected to the top of the lower support frame 111. The lower support frame 111 is used as the installation base of the upper protective cover 112. The lower support frame 111 bears the weight of the battery 200, and the upper protective cover 112 only plays a protective role. Therefore, the lower support frame 111 with higher strength requirements and the upper protective cover 112 with lower strength requirements can be manufactured independently, so as to reduce the production cost while meeting the strength standards of the main warehouse body 11, and also facilitate the transportation and installation of the main warehouse body 11.

[0068] Reference Figure 6 Furthermore, the side compartment body 12 includes a side protective cover 121 and a leg 122. A plurality of legs 122 are provided at the bottom of the side protective cover 121. Four legs 122 are used as an example in this embodiment, and one leg 122 is provided at each of the four corners corresponding to the side protective cover 121. One end of the leg 122 is rotatably provided on the side protective cover 121, and the leg 122 can be rotated to an unfolded state in which the other end is away from the side protective cover 121 and a folded state in which the other end is attached to the side protective cover 121.

[0069] Specifically in this embodiment, the side wall of one end of each leg 122 is rotatably connected to the side protective cover 121, and the other end of each leg 122 is connected to a positioning piece 1221 with a positioning hole. When the leg 122 is rotated to the unfolded state, the leg 122 is vertically arranged and the top of the leg 122 abuts against the side protective cover 121, thereby supporting the side protective cover 121; when the leg 122 is rotated to the unfolded state, the leg 122 is vertically arranged and the top of the leg 122 abuts against the side protective cover 121, thereby supporting the side protective cover 121. When the leg 122 is rotated to the folded state, the leg 122 is nearly horizontal and the positioning hole is located on one side of the side protective cover 121. The leg 122 can be limited by inserting a pin into the positioning hole and passing through the side protective cover 121, thereby reducing the overall height of the side warehouse body 12, so as to transport the side warehouse body 12.

[0070] Reference Figure 5 A canopy 15 is also provided above the parking area 100. The canopy 15 is L-shaped, one side of the canopy 15 is connected to the main compartment 11, and the side of the canopy 15 facing away from the main compartment 11 is fixed to the ground. The canopy 15 protects the parking area 100 in rainy and snowy weather to improve the safety of the battery replacement operation.

[0071] Reference Figure 3 , Figure 4 and Figure 8, Further, among the three placement positions 13 distributed along the second horizontal direction in each row, heightening seats are provided at the two placement positions 13 at both ends, and a lifting mechanism 3 is provided at the placement position 13 between the two heightening seats. The lifting mechanism 3 can receive the battery 200 and drive the battery 200 to lift and lower in the vertical direction. The lifting mechanism 3 can rise to a first height and can descend to a second height, and the height of the heightening seat is greater than the second height. Optionally, in some other embodiments, if the number of placement positions 13 in each row is four, then the lifting mechanism 3 is provided at the two placement positions 13 between the two heightening seats.

[0072] From the above, during battery swapping, if the depleted battery 200 needs to be placed on the lifting mechanism 3, that is, the empty working position corresponds to the lifting mechanism 3, and the fully charged battery 200 is located on the heightening seat; the telescopic arm 23 of the battery swapping robot 2 extends above the depleted battery 200 and hoists the depleted battery 200, and the lifting mechanism 3 rises synchronously to the first height. When the telescopic arm 23 of the battery swapping robot 2 contracts above the lifting mechanism 3, the depleted battery 200 is directly unloaded onto the lifting mechanism 3 at the first height, shortening the downward movement distance required for unloading the depleted battery 200, thereby shortening the battery swapping time. Then, the battery swapping robot 2 moves above the fully charged battery 200, and the battery 200 is driven by the lifting mechanism 3 to descend to the second height; then, the battery swapping robot 2 directly hoists the fully charged battery 200 on the heightening seat. Since the heightening seat is higher than the second height, the height ( Figure 4 H in it) for lifting the battery 200 here is less than the height of the battery 200, thereby reducing the lifting distance required for hoisting the battery 200.

[0073] In another case, that is, if the depleted battery 200 needs to be placed on the heightening seat and the fully charged battery 200 is located on the lifting mechanism 3, then the depleted battery 200 is first unloaded onto the heightening seat, and the downward movement distance required for unloading the battery 200 ( Figure 4 H in it) is also shortened during this process. During the downward movement of the depleted battery 200, the lifting mechanism 3 rises synchronously to the first height to lift the fully charged battery 200 to the first height, reducing the lifting distance required for hoisting the battery 200, and the battery swapping time can also be shortened, improving the efficiency of battery swapping.

[0074] Finally, by raising the height of some batteries 200 and cooperating with the lifting mechanism 3 for operation, the time for the battery swapping robot 2 to move in the vertical direction can be shortened. In addition, the time for the battery swapping robot 2 to move in the second horizontal direction and the first horizontal direction has been shortened in the previous text, resulting in a significant reduction in the final battery swapping time and a significant improvement in work efficiency.

[0075] Refer to Figure 3 and Figure 8, Further, each lifting mechanism 3 includes a chassis 31, a lifting seat 32 and a driving assembly 33. The lifting seat 32 is slidably arranged on the chassis 31 in the vertical direction, and the lifting seat 32 can receive and position the battery 200. The driving assembly 33 is arranged on the chassis 31, and the driving assembly 33 is configured to drive the lifting seat 32 to lift. The chassis 31 serves as the base of the lifting mechanism 3 to support and limit the lifting seat 32, and at the same time, the driving assembly 33 drives the lifting seat 32 to move.

[0076] Referring to Figure 8 , Exemplarily, the chassis 31 includes a bottom plate 311, columns 312 and slide rails 3221. A set of columns 312 are arranged on both opposite sides of the lifting seat 32. In this embodiment, the two sets of columns 312 are distributed along the second horizontal direction, and two columns 312 are arranged along the first horizontal direction in each set. In other embodiments, three or more columns 312 can be arranged in each set. The bottom plate 311 is connected to the bottom of each column 312, and the bottom plate 311 can be fixed to the ground by bolts to fix the columns 312.

[0077] Further, a slide rail 3221 is connected to the side of each column 312 close to the lifting seat 32. The slide rail 3221 is vertically arranged, and a slider 3211 is slidably connected to each slide rail 3221. The slider 3211 is connected to the lifting seat 32. Thus, the lifting seat 32 is guided and limited through the cooperation of the slide rail 3221 and the slider 3211.

[0078] In addition, the chassis 31 further includes a strengthening column 314. The strengthening column 314 is located on the side of the column 312 facing away from the lifting seat 32, and the strengthening column 314 is connected between the bottom plate 311 and the column 312. The strengthening column 314 in this embodiment is vertically arranged. The bottom end of the strengthening column 314 is connected to the bottom plate 311, and the strengthening column 314 and the column 312 are connected by a plurality of horizontally arranged connecting columns 3141 to assist in supporting the column 312. A strengthening beam 3142 is connected between all the strengthening columns 314 of the lifting seat 32. The strengthening beam 3142 is arranged in two in the vertical direction to further strengthen the strengthening column 314.

[0079] Optionally, in some other embodiments, the strengthening column 314 can also be inclined, and the top end of the strengthening column 314 is connected to the column 312, so that a triangle is formed between the bottom plate 311, the strengthening column 314 and the column 312.

[0080] Referring to Figure 9, Further, the lifting seat 32 includes a lifting beam 321, a receiving plate 322, and a positioning beam 323. There are two lifting beams 321 arranged at intervals along the second horizontal direction. The lifting beams 321 are vertically arranged and are square frames. The slider 3211 is connected to the side of the lifting beam 321 close to the column 312. The receiving plate 322 is connected between the two lifting beams 321, and the receiving plate 322 can receive and position the battery 200; the positioning beam 323 is connected between the two lifting beams 321, and the positioning beam 323 can receive and position the battery 200. In this embodiment, there are two receiving plates 322 and two positioning beams 323 both arranged along the first horizontal direction. In some other embodiments, more receiving plates 322 and positioning beams 323 can also be provided. The lifting seat 32 with a frame structure is formed by the cooperation of the lifting beam 321, the receiving plate 322, and the positioning beam 323, which ensures its own structural strength while reducing weight, and maintains a certain contact area between the receiving plate 322 and the battery 200.

[0081] Exemplarily, one driving component 33 is provided corresponding to each group of columns 312 in this embodiment. Each driving component 33 includes a lead screw 331 and a driving member 332. The lead screw 331 is rotatably connected to the cross beam 313. A driving block 3212 is threadedly connected to the lead screw 331, and the driving block 3212 is connected to the lifting beam 321. The driving member 332 is connected to the chassis 31. In this embodiment, the driving member 332 is a motor, and there is a belt drive between the motor and the lead screw 331. By simultaneously driving the two lead screws 331 to rotate by two motors, the driving block 3212 drives the lifting beam 321 to move up and down. In some other embodiments, the lifting beam 321 can also be driven to move up and down by components such as a cylinder or an electric cylinder.

[0082] Refer to Figure 8 and Figure 10 , Further, a charging beam 315 is connected to the chassis 31. Both ends of the charging beam 315 are connected to the reinforcing beam 3142. A charging head 4 is connected above the charging beam 315, and the charging head 4 is connected to the power grid through a cable below. The position of the lifting seat 32 corresponding to the charging head 4 is hollowed out. When the lifting seat 32 descends to the second height, the charging head 4 is docked with the battery 200, thereby charging the battery 200. The charging head 4 is fixedly arranged on the reinforcing beam 3142, so that the charging head 4 does not need to move up and down with the lifting seat 32, preventing the cable from getting fatigued.

[0083] In addition, an elastic member 41 is connected between the charging beam 315 and the charging head 4. In this embodiment, the elastic member 41 is taken as a spring, so that there is a certain elastic margin between the charging head 4 and the charging beam 315 to compensate for the deviation between the battery 200 and the charging head 4 in the height direction and the horizontal direction.

[0084] For example, the booster seat in this embodiment is welded from steel pipes, and a positioning plate having the same structure as the lifting seat 32 is also provided on the top thereof, and a charging head 4 is provided, so as to achieve the receiving and precise positioning of the battery 200. Optionally, in some other embodiments, the booster seat may be a flat plate or a support frame welded inside the warehouse body.

[0085] Reference Figure 4 , exemplarily, the battery-swapping robot 2 is located inside the battery compartment 1 on one side close to the parking area 100, and the battery-swapping robot 2 includes a telescopic arm 23, which is located inside the battery compartment 1, and can slide at least in the vertical direction and the second horizontal direction, and can hoist the battery 200, and the telescopic arm 23 itself can be bidirectionally extended along the first horizontal direction, that is, the telescopic arm 23 of this embodiment can be extended forward to the parking area 100, and can also be extended backward to the side warehouse body 12, so that the battery 200 can reach the parking area 100 and enter the side warehouse body 12 only by the extension and contraction of the telescopic arm 23, and the battery-swapping robot 2 does not need to move along the first horizontal direction. Optionally, if a unidirectionally retractable telescopic arm 23 is selected, an additional driving member 332 can also be provided to drive the telescopic arm 23 to move along the first horizontal direction.

[0086] Specifically, a support frame 16 is provided inside the battery compartment 1, and the support frame 16 includes two frame pieces 161 spaced apart along the second horizontal direction, the frame pieces 161 are vertically arranged, and the bottom of the frame pieces 161 is connected to the lower support frame 111. The lifting platform 21 is located between the two frame pieces 161. The battery-swap robot 2 also includes a lifting platform 21 and a sliding platform 22. The opposite sides of the lifting platform 21 are respectively slidably connected to the two frame pieces 161. The sliding between the lifting platform 21 and the frame piece 161 is guided and limited by the cooperation of the guide rail and the slider, and the lifting platform 21 is driven to slide by the screw. The sliding platform 22 is slidably arranged on the lifting platform 21 along the second horizontal direction. The sliding between the sliding platform 22 and the lifting platform 21 is guided and limited by the cooperation of the guide rail and the slider, and the lifting platform 21 is driven to slide by the screw. Optionally, in some other embodiments, the sliding lifting platform 21 and the sliding platform 22 may be guided and limited by other methods; optionally, in some other embodiments, the lifting platform 21 and the sliding platform 22 may be driven to slide by other driving components 332 such as a cylinder or an oil cylinder.

[0087] Furthermore, the telescopic arm 23 is located at the bottom of the sliding platform 22. The telescopic arm 23 in this embodiment is any bidirectional telescopic arm 23 capable of hoisting the battery 200. Its specific structure is the prior art and will not be repeated here.

[0088] Reference Figure 5, It should be noted that since the height of the side protective cover 121 only needs to accommodate the telescopic arm 23, the height of the side protective cover 121 can be reduced. In this embodiment, the heights of the lower support frame 111, the upper protective cover 112, and the side protective cover 121 are similar, which facilitates the disassembly and transportation of the battery compartment 1. The lower support frame 111, the upper protective cover 112, and the side protective cover 121 can be transported at one time by a single flatbed truck without exceeding the height limit. During transportation, the lifting mechanism 3 inside the side compartment 12 can be moved upward and fixed inside the side protective cover 121 for convenient transportation. At the same time, the legs 122 at the bottom of the side protective cover 121 can be placed on both sides of the flatbed truck, so that the bottom of the side protective cover 121 is directly placed on the flatbed truck, which is not only more stable but also reduces the height of the side protective cover 121.

[0089] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
