Description

[0001] This application is a division of a Chinese invention patent with an application date of December 2, 2021, application number 202111460199.2, and name “Battery transport equipment and battery swap station containing the same”. Technical Field

[0002] The present invention relates to the technical field of vehicle battery replacement, and in particular to a battery transfer device and a battery replacement station comprising the same. Background Art

[0003] When replacing the battery of an existing electric vehicle, it is usually necessary to remove the depleted battery from the electric vehicle and transport it to the battery rack, and to remove the fully charged battery from the battery rack and transport it to the electric vehicle. The component that realizes the battery taking and placing relative to the battery rack is the battery transfer equipment. Among them, the batteries are usually stored in the form of stacking on the battery rack. Therefore, when the battery transfer equipment takes out or places the battery, it is not only necessary for the battery transfer equipment to move in the horizontal direction or vertical direction to correspond to different battery positions; specifically, the battery taking and placing mechanism in the battery transfer equipment is configured to be able to move up and down to achieve matching with different battery positions. Based on this structure, since the battery taking and placing mechanism can be movably set, and it is also necessary to move after loading the battery, the requirements for structural stability are very high for the battery transfer equipment, which is a lifting and moving device. It is necessary to avoid shaking, impact and noise during movement, resulting in a high cost of the battery transfer equipment. Moreover, with different movement mode settings, the structure and cost of the battery transfer equipment will also change. Summary of the invention

[0090] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0091] The present invention provides a battery swap station 100, the structure of which is as follows: Figure 1As shown, in order to facilitate the display of the internal layout of the battery swap station 100, part of the top plate located on the top of the battery swap station 100 is hidden. In this embodiment, the battery swap station 100 includes a first battery swap module 101, a driving lane 102, and a second battery swap module 103 from left to right. When the vehicle to be battery swapped enters and stops at a specific position in the driving lane 102, the battery swap cart removes the battery from the bottom of the vehicle and moves it to the left or right to the first battery swap module 101 or the second battery swap module 103. Here, the transportation of the battery to the second battery swap module 103 is taken as an example: after the battery swap cart moves the battery to the second battery swap module 103, the battery transfer equipment 10 in the second battery swap module 103 removes the battery from the battery swap cart and places it on a battery compartment 201 of the battery rack 20, so that the battery rack 20 performs charging operations on the battery. Afterwards, the battery transfer equipment 10 takes out another fully charged battery from another battery compartment 201 on the battery rack 20 and transports the battery to the battery swap cart. The battery swap cart transports the battery to the bottom of the vehicle by horizontal movement and installs it on the vehicle to achieve the purpose of battery swap.

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

[0093] The structure of the battery transport device 10 is as follows Figure 4 As shown, the battery transport device 10 specifically includes: a support mechanism 1, a battery pick-up and placement mechanism 2, a transmission mechanism 3 and a counterweight mechanism 8. The support mechanism 1 is arranged adjacent to the battery rack 20, the battery pick-up and placement mechanism 2 is used to pick up and place the battery relative to any battery position 201 in the battery rack 20, and the transmission mechanism 3 is used to drive the battery pick-up and placement mechanism 2 to move up and down, so as to achieve the purpose of driving the battery to move up and down through the lifting and moving of the battery pick-up and placement mechanism 2. The counterweight mechanism 8 is connected to the battery pick-up and placement mechanism 2 through a chain, and the moving direction of the chain is changed through a pulley set, so that when the battery pick-up and placement mechanism 2 rises, the counterweight mechanism 8 is synchronously lowered, and when the battery pick-up and placement mechanism 2 is lowered, the counterweight mechanism 8 is synchronously raised, so as to achieve the purpose of counterweighting.

[0094] The battery transport device 10 is fixed to the top and bottom of the battery swap station 100 through the top and bottom of the support mechanism 1 respectively through the top connection unit 4 and the bottom connection unit 5 to form an integrated structure. Figure 5As shown, by connecting the top and bottom of the support mechanism 1 to the battery swap station 100 through the top connection unit 4 and the bottom connection 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 between the battery transport equipment 10 and the battery swap station 100, so that the noise and impact generated by the operation of the battery transport equipment 10 can be transmitted and dispersed, and the operation stability and reliability are improved. At the same time, by connecting the top and bottom of the support mechanism 1 of the battery transport 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 transport equipment 10 share part of the load, so that the structural strength requirements of the support mechanism 1 itself are reduced, so that the structure and material thickness of the support mechanism 1 can be simplified, and the purposes of reducing costs and weight can be achieved.

[0095] In addition, if Figure 5 As shown, on the side of the support mechanism 1 of the battery transport device 10 facing the battery rack 20, the first connection unit 6 is provided to achieve the purpose of fixing the support mechanism 1 with the battery rack 20 as an integral structure. Correspondingly, on the side of the support mechanism 1 away from the battery rack 20, the second connection unit (not shown in the figure) is provided to fix the support mechanism 1 with the side wall of the battery swap station 100 as an integral structure. By providing the first connection unit 6 and the second connection 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 integral structure, so that the battery rack 20 and the battery swap station 100 can further help the support mechanism 1 share part of the load caused by battery transport, so that the structural strength requirements of the support mechanism 1 itself are further reduced, and the purpose of simplifying the structure and material thickness of the support mechanism 1 is achieved.

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

[0097] Specific as Figure 6 As shown, in this embodiment, the bottom connection unit 5 includes: a connection base 51 and a reinforcement plate 52. Among them, the connection base 51 is located at the bottom of the battery transfer equipment 10 and covers the bottom platform 104 of the battery swap station 100, so as to achieve a larger area of ​​contact with the bottom of the battery swap station 100, facilitate the transmission of force, and improve the stability of the connection. The four columns 11 at the end corner positions of the support mechanism 1 corresponding to the battery pick-up and placement mechanism 2 are all fixed on the upper surface of the connection base 51 by welding. At the corner position of the column 11 relative to the connection base 51, a plurality of reinforcement plates 52 are also provided to achieve further reinforcement. The adjacent side surface of the reinforcement plate 52 is fixed to the upper surface of the connection base 51 by welding, and the adjacent other side surface is fixed to the side of the column 11 by welding, so as to achieve the reinforcement of the connection base 51 by the column 11.

[0098] A first mounting hole 511 is provided on the surface of the connection base 51, which is through from top to bottom. The first mounting hole 511 is used for screws to penetrate, 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 holes 511 are respectively provided at the four end corners of the connection base 51. Such a provision can not only ensure the multi-point connection of the connection base 51 relative to the battery swap station 100, but also avoid the installation of the screws due to the installation of the support mechanism 1. Of course, in other embodiments, the connection base 51 can also be connected to the bottom of the battery swap station 100 by other installation methods, so that the force acting on the support mechanism 1 of the battery transport equipment 10 is effectively transmitted to the bottom of the battery swap station 100, thereby improving the overall structural strength and effectively reducing costs.

[0099] like Figure 7 As shown, the connection base 51 in this embodiment is not a one-piece steel structure, but is formed by different structural parts through welding. The connection base 51 includes a base longitudinal beam 51a and a base connecting plate 51b symmetrically arranged on both sides. The base longitudinal beam 51a is a U-shaped steel with an opening facing, and the base connecting plate 51b is a plate-like structure, whose side is against the side of the base longitudinal beam 51a, and the two are welded. The upper surface of the base connecting plate 51b is used to open the first mounting hole 511, and the upper surface of the base longitudinal beam 51a is used for welding and connecting the column 11. At least two base cross beams 51c are arranged between the left and right groups of base longitudinal beams 51a and the base connecting plate 51b, and the two ends of the base cross beam 51c are respectively welded to the side surface of the base longitudinal beam 51a to form a complete connection base 51 structure. The connection base 51 is formed by this combined welding method, which not only meets the force and strength at a specific position, but also saves materials and achieves the purpose of reducing weight and reducing costs.

[0100] like Figure 8 and Fig. 9 As shown, in this embodiment, the top surface connection unit 4 includes a horizontal connection member 41 and an adjustment member 42 .

[0101] Among them, there are two horizontal connecting members 41, which are respectively arranged along a direction relatively parallel to the top surface 12 of the support mechanism 1, and are located directly above the top surface 12 of the support mechanism 1. The number of horizontal connecting members 41 is at least two, and the horizontal connecting members 41 are arranged in parallel and are distributed at least at both ends of the top surface 12 of the support mechanism 1. Both ends of these horizontal connecting members 41 are connected to the top frame 105 of the battery swap station 100, thereby realizing an integrated connection of the top surface 12 of the support mechanism 1 relative to the battery swap station 100.

[0102] Each horizontal connector 41 has a second mounting hole 411 at both ends. The horizontal connector 41 is fixed to the side surface of the top frame 105 at the top of the battery swap station 100 by screwing the screws through the second mounting holes 411. In addition, to meet the shock absorption requirements, a shock absorbing pad 43 is provided between the horizontal connector 41 and the top frame 105 of the battery swap station 100 (see Fig. 9 ), the shock-absorbing pad 43 can not only achieve the purpose of shock absorption, but also provide a pre-tightening force for the screws fixing the horizontal connecting member 41 relative to the battery swap station 100, thereby preventing the screws from loosening during long-term operation.

[0103] An adjustment member 42 is provided between the horizontal connection member 41 and the top surface 12 of the support mechanism 1. The adjustment member 42 is used to realize the connection of the horizontal connection member 41 relative to the top surface 12 of the support mechanism 1, and the adjustment member 42 can adjust the distance between the horizontal connection member 41 and the top surface 12 of the support mechanism 1 in the vertical direction. Therefore, by providing the adjustment member 42, a top surface connection unit 4 connected to the battery swap station 100 is formed in an upwardly extending manner at the top surface 12 of the support mechanism 1, so that the setting of the top surface connection unit 4 does not need to consider the height of the support mechanism 1, so as to adapt to battery transport equipment 10 of different heights, and has high versatility. Among them, the specific structure of the adjustment member 42 in this embodiment is as follows:

[0104] like Fig.10 As shown, the adjusting member 42 is a columnar structure, and the cylindrical surfaces of the top and bottom ends thereof are provided with external threads, wherein the external thread 42a at the top end of the adjusting member 42 is used to be fixedly connected with the lower surface of the corresponding horizontal connecting member 41 to be fixed into an integrated structure; and the external thread 42b at the bottom end of the adjusting member 42 is used to be connected with the internal thread of the third mounting hole 13 provided on the top surface 12 of the supporting mechanism 1. By rotating the adjusting member 42, the adjusting member 42 can be adjusted in the height direction relative to the top surface 12 of the supporting mechanism 1, thereby driving the horizontal connecting member 41 to achieve the adjustment in the height direction. Therefore, this structural setting scheme has a simple structure and high reliability. In this embodiment, a horizontal connecting member 41 is connected to the top surface 12 of the supporting mechanism 1 by two adjusting members 42 at both ends. Therefore, when adjusting the height of the horizontal connecting member 41, it is necessary to rotate the two adjusting members 42. In addition, when multiple adjustment parts 42 are simultaneously fixing a horizontal connecting part 41, the horizontality of the horizontal connecting part 41 can be changed by adjusting the height of some of the adjustment parts 42 relative to the top surface 12 of the supporting mechanism 1, thereby meeting the relatively high hole alignment and connection requirements between the horizontal connecting part 41 and the battery swap station 100.

[0105] Among them, after changing the height of the adjusting member 42 relative to the top surface 12 of the supporting mechanism 1 by rotating the adjusting member 42, in order to maintain the height of the adjusting member 42 relative to the supporting mechanism 1 and avoid the external impact generated by the continuous operation of the battery transfer equipment 10 causing the adjusting member 42 to move slightly relative to the supporting mechanism 1 and cause height changes, in this embodiment, a plurality of nuts are additionally arranged on the external thread 42b at the bottom end of the adjusting member 42, and the self-locking effect generated by the contact between the nuts is used to ensure that the height position of the adjusting member 42 relative to the supporting mechanism 1 will not change.

[0106] In addition, in this embodiment, Fig.11 and Fig.12 As shown, after the battery transport equipment 10 is hoisted relative to the battery swap station 100, the top surface connection unit 4 is installed on the top of the battery transport equipment 10. Therefore, the third mounting hole 13 set on the top surface 12 of the support mechanism 1 of the battery transport equipment 10 is also reused as a structure for the installation of the hoisting member 9 when the top surface connection unit 4 is not installed. Through this structural setting, when the battery transport equipment 10 is to be hoisted into the battery swap station 100, the third mounting hole 13 for the installation of the adjustment member 42 is used to achieve the purpose of temporarily installing the hoisting member 9, meeting the hoisting requirements. 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 at the same time.

[0107] like Fig.13 As shown, in this embodiment, the specific structure of the column 11 of the support mechanism 1 for the installation of the first connection unit 6 and the second connection unit is as follows: the column 11 is composed of a longitudinally extending steel member 111 and a plurality of connecting plates 112 welded to the steel member 111, wherein the cross section of the steel member 111 is U-shaped, the connecting plate 112 is installed on one side of the U-shaped notch of the steel member 111, the connecting plate 112 is welded to the two ends of the U-shaped steel member 111 on both sides along the length direction, and a fourth mounting hole 1121 for connecting the first connection unit 6 or the second connection unit is provided on the surface of the connecting plate 112, and the fourth mounting hole 1121 can be a threaded hole for fixing by a screw. The column 11 is arranged in this structure, so that the column 11 can save the material of the column 11 on the basis of realizing the function of connecting the first connection unit 6 or the second connection unit, thereby achieving the purpose of cost reduction and weight reduction.

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

[0109] like Fig.14As shown, in this embodiment, the first connection unit 6 has a first mounting plate 61 and a second mounting plate 62 which are arranged at a 90° angle 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 to the fourth mounting hole 1121 of the connecting plate 112 of the column 11 by screws. The first mounting plate 61 and the second mounting plate 62 form a 90° angle between them, so as to facilitate the connection of the battery rack 20 and the supporting mechanism 1 of the battery transport equipment 10 from different directions, thereby leaving enough installation controls, so that the construction personnel can realize the fixed connection of the battery rack 20 relative to the battery transport equipment 10 by means of fasteners such as mounting bolts in different directions.

[0110] For specific connection scheme, see Fig.15 , wherein the screws for installing the first connecting unit 6 are not shown, from which it can be seen that the hole on the first mounting plate 61 for connecting the supporting column of the battery rack 20 is a horizontally extending waist-shaped hole 621, and the hole on the second mounting plate 62 for connecting the column 11 of the supporting mechanism 1 is a vertically extending waist-shaped hole 621. By arranging the waist-shaped holes 621 along different directions, position adjustment along different directions is achieved. The first connecting unit 6 is installed after the battery rack 20 and the battery transport equipment 10 are hoisted. The above-mentioned structural arrangement can facilitate the hole-to-hole installation of the battery rack 20 and the battery transport equipment 10 of the first connecting unit 6.

[0111] In addition, from Fig.15 It can be seen that each first connecting unit 6 is also provided with a triangular reinforcement plate 63 between the first mounting plate 61 and the second mounting plate 62. The reinforcement plate 63 is used to reinforce the angle of the first mounting plate 61 relative to the second mounting plate 62 to prevent the first connecting unit 6 from being deformed during long-term use and affecting the integrated connection between the battery rack 20 and the battery transport equipment 10.

[0112] In this embodiment, the structure of the second connection unit is substantially the same as that of the first connection unit 6, except that the second connection unit is mounted on the column 11 on the side of the support mechanism 1 facing the side wall of the battery swap station 100, and the other end of the second connection unit is fixedly mounted on the side wall surface of the battery swap station 100. Through the above-mentioned structural arrangement, the battery transport device 10 is integratedly connected to the side wall of the battery swap station 100 through the support mechanism 1 and the second connection unit, so that the force acting on the battery transport device 10 can be transmitted to the side wall of the battery swap station 100, further dispersing the noise and impact generated by the operation of the battery transport device 10, and improving the operational stability and reliability.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
