Among them, the batteries are usually stored in the form of stacking on the battery racks, so when the battery transfer equipment takes out or places the batteries, not only does the battery transfer equipment need to move in the horizontal or vertical direction to correspond to different battery positions, but specifically, the battery taking and placing mechanism in the battery transfer equipment is configured to be movable and lifted to match different battery positions.

[0090] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0091] This invention provides a battery swapping station 100, with the following structure: Figure 1As shown, to facilitate the demonstration of the internal layout of the battery swapping station 100, part of the top panel of the station is hidden. In this embodiment, the battery swapping station 100 includes, from left to right, a first battery swapping module 101, a driveway 102, and a second battery swapping module 103. When a vehicle to be swapped enters and stops at a specific position in the driveway 102, the battery swapping trolley removes the battery from the bottom of the vehicle and moves it to the left or right into the first battery swapping module 101 or the second battery swapping module 103. Taking the transportation of the battery to the second battery swapping module 103 as an example: after the battery swapping trolley moves the battery to the second battery swapping module 103, the battery transfer device 10 inside the second battery swapping module 103 removes the battery from the battery swapping trolley and places it on a battery compartment 201 of the battery rack 20, allowing the battery rack 20 to charge the battery. Then, the battery transfer device 10 takes out another fully charged battery from another battery compartment 201 in the battery rack 20, transports the battery to the battery swapping trolley, and the battery swapping trolley transports the battery to the bottom of the vehicle by horizontal movement and installs it on the vehicle to achieve the purpose of battery swapping.

[0092] Taking the second battery swapping module 103 of the battery swapping station 100 as an example, the specific layout of the second battery swapping module 103 is as follows: Figure 2 and Figure 3 As shown, the battery rack 20 in the second battery swapping module 103 is arranged on one side close to the driving lane 102. The battery compartments 201 on the battery rack 20 are stacked in sequence in the vertical direction. The battery transfer device 10 is arranged on the side of the battery rack 20 away from the driving lane 102.

[0093] The structure of the battery transfer device 10 is as follows: Figure 4 As shown, the battery transfer device 10 specifically includes: a support mechanism 1, a battery picking and placing mechanism 2, a transmission mechanism 3, and a counterweight mechanism 8. The support mechanism 1 is located adjacent to the battery rack 20. The battery picking and placing mechanism 2 is used to pick up and place batteries relative to any battery compartment 201 in the battery rack 20. The transmission mechanism 3 is used to drive the battery picking and placing mechanism 2 to move up and down, thereby achieving the purpose of lifting and lowering the batteries. The counterweight mechanism 8 is connected to the battery picking and placing mechanism 2 via a chain, and the direction of the chain's movement is changed by a pulley system, so that when the battery picking and placing mechanism 2 rises, the counterweight mechanism 8 descends synchronously, and when the battery picking and placing mechanism 2 descends, the counterweight mechanism 8 rises synchronously, achieving the purpose of counterweighting.

[0094] The battery transfer device 10 is fixed to the top and bottom of the battery swapping station 100 as an integral structure via a top surface connection unit 4 and a bottom surface connection unit 5, respectively, through the support mechanism 1. The structure of the bottom surface connection unit 5 is as follows: Figure 5As shown, by connecting the top and bottom of the support mechanism 1 of the battery transfer equipment 10 to the battery swap station 100 through the top surface connecting unit 4 and the bottom surface connecting unit 5, the support mechanism 1 and the top and bottom of the battery swap station 100 form an integrated structure, which strengthens the connection stability of the battery transfer equipment 10 and the battery swap station 100, so that the noise and impact generated by the operation of the battery transfer equipment 10 can be transmitted and dispersed, improving the operation stability and reliability. At the same time, by connecting the top and bottom of the support mechanism 1 of the battery transfer equipment 10 to the battery swap station 100, the frame structure of the battery swap station 100 can help the support mechanism 1 of the battery transfer equipment 10 to share part of the load, so that the structural strength requirement of the support mechanism 1 itself is reduced, and therefore the structure and material thickness of the support mechanism 1 can be simplified, achieving the purposes of reducing cost and weight.

[0095] In addition, as shown in the drawings, Figure 5 As shown, on the side of the support mechanism 1 of the battery transfer equipment 10 facing the battery rack 20, a first connecting unit 6 is provided to achieve the purpose of being fixed as an integrated structure with the battery rack 20. Correspondingly, on the side of the support mechanism 1 away from the battery rack 20, a second connecting unit (not shown in the drawings) is provided to be fixed as an integrated structure with the side wall of the battery swap station 100. By providing the first connecting unit 6 and the second connecting unit, the support mechanism 1 is fixed to the battery rack 20 and the side wall of the battery swap station 100 to form an integrated structure, so that the battery rack 20 and the battery swap station 100 can further help the support mechanism 1 to share part of the load from the battery transfer, so that the structural strength requirement of the support mechanism 1 itself is further reduced, achieving the purpose of simplifying the structure and material thickness of the support mechanism 1.

[0096] In this embodiment, a relatively better connecting structure of the top surface connecting unit 4, the bottom surface connecting unit 5, the first connecting unit 6 and the second connecting unit is also provided.

[0097] As shown in detail, Figure 6 As shown in detail,

[0098] A first mounting hole 511 is provided on the surface of the connecting base 51, which is used for the screw to pass through, so that the end of the screw is fixed in the corresponding threaded hole on the bottom platform 104 of the battery swap station 100. In this embodiment, the first mounting hole 511 is provided at the four corner positions of the connecting base 51 respectively. In this way, the multi-point connection of the connecting base 51 relative to the battery swap station 100 can be ensured, and the installation of the support mechanism 1 and the screw can be avoided. Of course, in other embodiments, the connecting base 51 can also be connected to the bottom of the battery swap station 100 through other installation methods, so that the force acting on the support mechanism 1 of the battery transfer equipment 10 is effectively transmitted to the bottom of the battery swap station 100, the overall structural strength is improved, and the cost is effectively reduced.

[0099] As shown in Figure 7 , the connecting base 51 in this embodiment is not an integral steel structure, but is formed by welding different structural parts. The connecting base 51 includes base longitudinal beams 51a and base connecting plates 51b arranged symmetrically on both sides. The base longitudinal beam 51a is a U-shaped steel with an opening facing upward, and the base connecting plate 51b is a plate-shaped structure with its side surface abutting against the side surface of the base longitudinal beam 51a, and the two are welded together. The upper surface of the base connecting plate 51b is used to form the first mounting hole 511, and the upper surface of the base longitudinal beam 51a is used for welding connection with the column 11. Between the left and right groups of base longitudinal beams 51a and base connecting plates 51b, at least two base cross beams 51c are arranged, and the two ends of the base cross beam 51c are welded to the side surfaces of the base longitudinal beams 51a respectively to form a complete connecting base 51 structure. The connecting base 51 is formed by this combined welding method, which not only meets the force and strength requirements at specific positions, but also saves materials and reduces weight and cost.

[0100] As shown in Figure 8 and Figure 9 , in this embodiment, the top connecting unit 4 includes horizontal connecting pieces 41 and adjusting pieces 42.

[0101] The horizontal connecting pieces 41 are arranged in parallel with the top surface 12 of the support mechanism 1 and above the top surface 12 of the support mechanism 1. The number of horizontal connecting pieces 41 is at least two, and each horizontal connecting piece 41 is arranged in parallel and distributed at least at both ends of the top surface 12 of the support mechanism 1. The two ends of each horizontal connecting piece 41 are connected to the top frame 105 of the battery swap station 100, so as to realize the integrated connection of the top surface 12 of the support mechanism 1 relative to the battery swap station 100.

[0102] For each horizontal connecting piece 41, both ends thereof are provided with second mounting holes 411, and the horizontal connecting piece 41 is fixed at the side surface of the top frame 105 of the battery swap station 100 by means of screwing the screw into the second mounting hole 411. In order to meet the shock absorption requirement, a shock absorption pad 43 (see Figure 9 ) is arranged between the horizontal connecting piece 41 and the top frame 105 of the battery swap station 100. The shock absorption pad 43 not only can achieve the purpose of shock absorption, but also can provide pre-tightening force for the screw for fixing the horizontal connecting piece 41 relative to the battery swap station 100, so as to avoid screw loosening in long-term operation.

[0103] An adjusting piece 42 is arranged between the horizontal connecting piece 41 and the top surface 12 of the support mechanism 1. The adjusting piece 42 is used to realize the connection of the horizontal connecting piece 41 relative to the top surface 12 of the support mechanism 1, and the adjusting piece 42 can adjust the distance between the horizontal connecting piece 41 and the top surface 12 of the support mechanism 1 in the vertical direction. Therefore, by arranging the adjusting piece 42, the top surface connecting unit 4 connected with the battery swap station 100 is formed in an upward expanding manner at the top surface 12 of the support mechanism 1, so that the arrangement of the top surface connecting unit 4 does not need to consider the height of the support mechanism 1, and is suitable for battery transfer equipment 10 of different heights, and has high universality. The specific structure of the adjusting piece 42 in the embodiment is as follows:

[0104] As shown in Figure 10 , the adjusting piece 42 is a columnar structure, and the columnar surfaces at the top end and the bottom end thereof are provided with external threads. The external thread 42a at the top end of the adjusting piece 42 is used to be fixedly connected with the lower surface of the corresponding horizontal connecting piece 41, so as to be fixed as an integrated structure. The external thread 42b at the bottom end of the adjusting piece 42 is used to be connected with the internal thread of the third mounting hole 13 opened on the top surface 12 of the support mechanism 1. By rotating the adjusting piece 42, the adjusting piece 42 can be adjusted in the height direction relative to the top surface 12 of the support mechanism 1, and further drives the horizontal connecting piece 41 to be adjusted in the height direction. Therefore, the structure of this arrangement scheme is relatively simple and has high reliability. In the embodiment, one horizontal connecting piece 41 is connected to the top surface 12 of the support mechanism 1 by two adjusting pieces 42 at both ends. Therefore, when the height of the horizontal connecting piece 41 is adjusted, the two adjusting pieces 42 need to be rotated. In addition, when a plurality of adjusting pieces 42 fix one horizontal connecting piece 41, by adjusting the height of part of the adjusting pieces 42 relative to the top surface 12 of the support mechanism 1, the horizontal degree of the horizontal connecting piece 41 can be changed, and further the relatively high hole alignment and connection requirement between the horizontal connecting piece 41 and the battery swap station 100 can be met.

[0105] Wherein, after changing the height of the adjustment member 42 relative to the top surface 12 of the support mechanism 1 by rotating the adjustment member 42, in order to keep the height of the adjustment member 42 relative to the support mechanism 1 from changing due to the micro-motion of the adjustment member 42 relative to the support mechanism 1 caused by the external impact generated by the continuous operation of the battery transfer device 10, in the embodiment, a plurality of nuts are additionally arranged on the external thread 42b at the bottom end of the adjustment member 42, and the self-locking effect generated by the contact between the nuts is used to ensure that the height position of the adjustment member 42 relative to the support mechanism 1 will not change.

[0106] In addition, in the embodiment, as shown in Figure 11 and Figure 12 , after the hoisting of the battery transfer device 10 relative to the battery swap station 100 is completed, the top surface connecting unit 4 is installed on the top of the battery transfer device 10, and therefore, the third mounting hole 13 arranged on the top surface 12 of the support mechanism 1 of the battery transfer device 10 is also used for mounting the hoisting member 9 in the case where the top surface connecting unit 4 is not installed. Through this structural arrangement, when the battery transfer device 10 is hoisted into the battery swap station 100, the third mounting hole 13 used for mounting the adjustment member 42 is used to temporarily mount the hoisting member 9, meeting the hoisting requirement. After the hoisting is completed, the hoisting member 9 is removed and the adjustment member 42 is installed, so that the third mounting hole 13 has two functions.

[0107] As shown in Figure 13 , in the embodiment, the specific structure of the stand column 11 of the support mechanism 1 for mounting the first connecting unit 6 and the second connecting unit is as follows: the stand column 11 is composed of a longitudinally extending steel member 111 and a plurality of connecting plates 112 welded on the steel member 111, wherein the cross section of the steel member 111 is U-shaped, the gap side of the U-shaped steel member 111 is provided with the connecting plate 112, the connecting plate 112 is welded on both ends of the U-shaped steel member 111 along the length direction, and the fourth mounting hole 1121 for connecting the first connecting unit 6 or the second connecting unit is arranged on the surface of the connecting plate 112, which can be a threaded hole for being fixed by a screw. Through this structural arrangement of the stand column 11, the stand column 11 can save materials and achieve the purposes of reducing cost and weight while realizing the function of connecting the first connecting unit 6 or the second connecting unit.

[0108] Corresponding to the structure of the stand column 11 described above, the first connecting unit 6 or the second connecting unit can adopt the following structure to realize the connection of the stand column 11 relative to the battery rack 20 or the side wall of the battery swap station 100, and here, the specific structure of the first connecting unit 6 is taken as an example:

[0109] As shown in Figure 14As shown, in the embodiment, the first connecting unit 6 has a first mounting plate 61 and a second mounting plate 62 arranged at an angle of 90° relative to each other, wherein the first mounting plate 61 is used to connect with the support column of the battery rack 20, and the second mounting plate 62 is fixed on the fourth mounting hole 1121 of the connecting plate 112 of the stand column 11 by screws. The first mounting plate 61 and the second mounting plate 62 are arranged at an angle of 90° relative to each other, so as to connect the battery rack 20 and the support mechanism 1 of the battery transfer device 10 from different directions respectively, so as to leave enough installation control, and facilitate the construction personnel to fasten the installation bolts and the like from different directions, so as to realize the fixed connection of the battery rack 20 relative to the battery transfer device 10.

[0110] The specific connection scheme is shown in Figure 15 Wherein, the screws for mounting the first connecting unit 6 are not shown, and it can be seen that the hole for connecting the support column of the battery rack 20 on the first mounting plate 61 is a horizontally extending waist-shaped hole 621, and the hole for connecting the stand column 11 of the support mechanism 1 on the second mounting plate 62 is a vertically extending waist-shaped hole 621. By arranging the waist-shaped holes 621 in different directions, the position adjustment in different directions is realized, and the first connecting unit 6 is installed after the hoisting of the battery rack 20 and the battery transfer device 10 is completed. The above structure can facilitate the hole alignment installation of the first connecting unit 6 relative to the battery rack 20 and the battery transfer device 10.
