Description

Technical Field

[0001] The present invention belongs to the field of vehicle battery replacement, and specifically relates to a battery lifting and reversing device and a battery replacement station. Background Art

[0002] A battery swap station is an automated device for replacing batteries in electric vehicles. Existing battery swap stations are mainly composed of battery compartments, battery racks, battery transport devices, and battery swap devices. When an electric vehicle enters a battery swap station, the battery swap device will remove the empty battery, and then use the battery transport device to transport the empty battery to the battery rack, remove the full battery from the battery rack, transport it to the battery swap device, and then the battery swap device will install the full battery on the electric vehicle, thus completing the entire battery swap process.

[0003] In the prior art, a stacker can be used as a battery transport device, and a fork can be used to pick up and place batteries from a battery rack. However, a stacker usually places a lifting mechanism such as a motor on its top, which occupies too much space on the top and limits the lifting height of the fork. Since both the stacker and the battery rack are placed inside the battery compartment, especially when a container is used as the battery compartment, the height inside the battery compartment is limited. When the battery rack is too high and the height inside the battery compartment is insufficient, the stacker will not be able to pick up and place the batteries on the highest layer of the battery rack, making it impossible to place batteries on the top layer of the battery rack, which cannot meet actual needs.

[0004] Alternatively, a battery transfer transmission device is provided in the battery compartment as a battery transport device. The battery transfer transmission device is provided on one side of the battery rack, and the batteries on the battery rack are taken and placed, and then the batteries are transported between the battery exchange device through an external transmission mechanism. However, the lifting mechanism of the battery transfer transmission device is usually also provided on the top thereof, resulting in excessive space being occupied on the upper part of the battery transfer transmission device. When the battery rack is too high and the height in the battery compartment is insufficient, the batteries on the highest layer of the battery rack cannot be taken and placed, and the battery use needs cannot be met.

[0005] Furthermore, after the battery transport device removes the battery from the battery rack, it needs to quickly transport the battery to the battery replacement device. However, the battery transport device has a large footprint and a slow connection and transmission speed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the technical problem in the prior art that the lifting mechanism occupies too much space above the battery transport device, making it impossible to take and place the top layer of batteries on the battery rack, and requiring an external transport mechanism to cooperate in the connection and transmission.

[0053] like Figures 1 to 6As shown, the battery lifting and reversing device of the present invention includes a lifting platform 2, a frame 1, a lifting mechanism 3 and a transfer mechanism 5.

[0054] The lifting platform 2 is used to transfer batteries in the horizontal direction. The lifting platform 2 is movably arranged in the frame 1. The lifting mechanism 3 is installed on the lifting platform 2, and is used to cooperate with the frame 1 to drive the lifting platform 2 to move up and down. The transfer mechanism 5 is arranged at the bottom of the frame 1, below the lifting platform 2, and is used to connect with the lifting platform 2 for transmission.

[0055] The present invention sets a lifting mechanism 3 on the lifting platform 2. The lifting mechanism 3 can cooperate with the frame 1 to move up and down along the frame 1, driving the lifting platform 2 to move up and down, without occupying a large amount of space on the upper part of the frame 1, so that the battery lifting and reversing device can move upward to the top layer of the battery rack to take and place the batteries on the upper layer of the battery rack, thereby increasing the battery capacity of the battery rack and reducing the cost and failure rate of battery taking and placing. The structure is more compact and the cost is reduced. At the same time, the battery lifting and reversing mechanism is used to take and place the battery, which can save space in the battery compartment and reduce the occupied area. It can be suitable for small battery swap stations and reduce the cost of landing. In addition, the present invention sets a transfer mechanism 5 at the bottom of the frame 1, which can be connected and transmitted with the lifting platform 2, and can transport the battery to the outside of the frame 1, occupying a small space and convenient for connection and transmission.

[0056] The lifting platform 2 cooperates with the battery rack to transfer the battery in the horizontal direction. The frame 1 is fixed on the ground of the battery swap station. The transfer mechanism 5 connects and transfers with the lifting platform 2 in the horizontal direction. The transfer mechanism 5 can cooperate with an external transmission mechanism to transport the battery to the battery swap device.

[0057] like Figure 1 to Figure 2 As shown, the lifting platform 2 is provided with an avoidance opening 26 for avoiding the transfer mechanism 5 when moving downward, so that the bearing surface of the transfer mechanism 5 is higher than the bearing surface of the lifting platform 2. The transmission direction of the transfer mechanism 5 is perpendicular to the transmission direction of the lifting platform 2.

[0058] Remove the battery from the battery rack, transfer the battery to the lifting platform 2, then control the lifting platform 2 to descend, avoid the transfer mechanism 5, lower it below the transfer mechanism 5, make the battery fall on the transfer mechanism 5, and use the transfer mechanism 5 and the external transmission mechanism to transport the battery to the battery replacement device.

[0059] Furthermore, the transfer mechanism 5 includes a bracket 52 and a roller 51 .

[0060] The bracket 52 is disposed opposite to the escape opening 26 and is located directly below the escape opening 26. The roller 51 is rotatably disposed on the bracket 52.

[0061] The support 52 includes a rectangular frame and four supporting feet. The supporting feet are arranged at the bottom of four right angles of the rectangular frame. The roller 51 is arranged in the rectangular frame, and the axial direction of the roller 51 extends along the length direction of the rectangular frame.

[0062] Furthermore, the battery lifting and reversing device further includes a transition transmission unit 53, which is arranged at the bottom of the frame 1 and can be fixed on the ground and located on both sides of the axial direction of the transfer mechanism 5. The transmission direction of the transition transmission unit 53 is the same as the transmission direction of the transfer mechanism 5.

[0063] The transition transmission unit 53 includes a support frame and a transition roller disposed on the upper portion of the support frame. The transition roller is parallel to the roller 51 and is disposed at the same height. An avoidance groove 27 is provided on the lifting platform 2 for moving downward to avoid the transition roller so that the bearing surface of the transition roller is higher than the plane of the lifting platform 2.

[0064] Furthermore, the lifting platform 2 also includes a transmission mechanism 4 , a blocking mechanism 22 and a positioning mechanism 23 .

[0065] The transmission mechanism 4 is arranged on the lifting platform 2, and is respectively located on both sides of the avoidance opening 26. The transmission direction of the transmission mechanism 4 is perpendicular to the transmission direction of the transfer mechanism 5. They are respectively located outside the width direction of the rectangular frame.

[0066] Through openings 25 extending along the axial direction of the roller 51 are respectively provided on both sides of the avoidance opening 26 of the lifting platform 2. The transmission mechanism 4 includes a chain transmission unit 41 extending along the axial direction of the roller 51 and arranged in the through opening 25 of the lifting platform 2.

[0067] The transmission mechanism 4 further includes a power unit 42. The power unit 42 is disposed at the bottom of the lifting platform 2 and connected to the chain transmission unit 41 to drive the chain transmission unit 41 to rotate forward and reversely.

[0068] Specifically, the chain transmission unit 41 includes a first chain transmission unit 411, a second chain transmission unit 412 and a fourth rotating shaft 413 which are arranged opposite to each other. The first chain transmission unit 411 and the second chain transmission unit 412 are connected via the fourth rotating shaft 413. The power unit 42 drives the fourth rotating shaft 413 to rotate forward and reversely, and the fourth rotating shaft 413 simultaneously drives the first chain transmission unit 411 and the second chain transmission unit 412 to transmit in the same direction.

[0069] The blocking mechanism 22 is arranged on the bottom wall of the lifting platform 2 and is located at the outer periphery of the transmission mechanism 4. The blocking mechanism 22 is telescopically arranged upward and downward through the lifting platform 2 to prevent the battery from continuing to move.

[0070] The present invention can transfer batteries in the horizontal direction by arranging a transmission mechanism 4 on the lifting platform 2. A retractable blocking mechanism 22 is arranged on the periphery of the transmission mechanism 4. When the battery moves from one end of the lifting platform 2 to the other end, the blocking mechanism 22 on one end of the lifting platform 2 retracts and does not protrude from the surface of the lifting platform 2, thereby ensuring that the battery passes smoothly. The blocking mechanism 22 on the other end of the lifting platform 2 protrudes, thereby preventing the battery from continuing to move outward and preventing the battery from falling off.

[0071] Preferably, the blocking mechanism 22 includes a connected telescopic cylinder and a telescopic block, the telescopic cylinder is arranged on the bottom wall of the lifting platform 2, and the telescopic block is telescopically arranged through the lifting platform 2.

[0072] The lifting platform 2 is further provided with rollers 24, which are located outside the two ends of the transmission direction of the chain transmission unit 41. The transmission direction of the rollers 24 is consistent with the transmission direction of the chain transmission unit 41. Two rollers 24 are respectively provided outside the two ends of the transmission direction of the chain transmission unit 41, extending along the same axis.

[0073] The positioning mechanism 23 is disposed on the bottom wall of the lifting platform 2 , and is telescopically arranged through the lifting platform 2 up and down, and is located at the periphery of the transmission mechanism 4 , and is used for positioning the battery.

[0074] When the battery moves from one end of the lifting platform 2 to the other end, the positioning mechanism 23 protrudes from the surface of the lifting platform 2, which can accurately position the battery during the transmission process and play a positioning role on the battery to prevent the battery from moving.

[0075] Preferably, the positioning mechanism 23 includes a connected telescopic cylinder and a telescopic rod, the telescopic cylinder is arranged on the bottom wall of the lifting platform 2, and the telescopic rod is telescopically arranged through the lifting platform 2.

The power unit 42 is a motor.

[0078] The present invention arranges the mobile unit and the driving unit 31 of the lifting mechanism 3 on the bottom wall of the lifting platform 2 without occupying the space above the lifting platform 2, so that the lifting platform 2 can be moved to the uppermost part of the frame 1 to take and place the batteries on the uppermost layer of the battery rack, thereby reducing the space occupied by the battery center switching device in the battery swap station and not occupying the space above the lifting platform 2, which can facilitate the connection and transmission of the lifting platform 2 with other transportation mechanisms.

[0079] The moving unit includes a first rotating shaft 32 and a first gear 321 .

[0082] When the driving unit 31 rotates forward, the first rotating shaft 32 is driven to rotate forward, driving the first gear 321 to move upward on the frame 1, thereby causing the lifting platform 2 to move upward on the frame 1. When the driving unit 31 rotates reversely, the first rotating shaft 32 is driven to rotate reversely, driving the first gear 321 to move downward on the frame 1, thereby causing the lifting platform 2 to move downward on the frame 1.

[0110] The present invention provides a fixing component 6. When the battery is transported normally, the fixing component 6 is not connected to the transfer mechanism 5. When an accident occurs to the battery, the battery needs to be transported to the fire extinguishing box on one side of the battery lifting and reversing device. The fixing component 6 is connected to the transfer mechanism 5, so that the transfer mechanism 5 is connected to the lifting platform 2 as a whole. As the lifting platform 2 moves up and down and faces the opening of the fire extinguishing box, the battery is transported to the fire extinguishing box by the transfer mechanism 5.

[0111] The fixing assembly 6 is arranged at the bottom of the lifting platform 2 and is respectively located on the outer sides of both ends of the transfer direction of the transfer mechanism 5 .

[0112] The fixing assembly 6 includes a mounting seat 61 and a telescopic unit 62 .

[0113] The mounting seat 61 is arranged on the bottom wall of the lifting platform 2. The telescopic unit 62 is telescopically arranged on the mounting seat 61, and is used to be detachably connected with the transfer mechanism 5. The telescopic unit 62 is a controllable automatic telescopic unit 62.

[0114] Furthermore, the fixing assembly 6 further comprises a positioning seat 63. The positioning seat 63 is arranged on the bottom of the lifting platform 2, and the telescopic unit 62 is telescopically arranged in the positioning seat 63.

[0115] The present invention provides a positioning seat 63 so that the telescopic unit 62 is inserted into the positioning seat 63 , thereby maintaining the stability of the telescopic direction of the telescopic unit 62 and ensuring a quick and accurate connection with the transfer mechanism 5 .

[0116] The lifting platform 2 is provided with an escape opening 26 for escaping the transfer mechanism 5 so that the bearing surface of the transfer mechanism 5 is higher than the bearing surface of the lifting platform 2. The fixing assembly 6 is arranged on the lifting platform 2 at the periphery of the escape opening 26.

[0117] When an accident occurs to the battery, the transfer mechanism 5 cannot directly push the battery into the fire extinguisher box due to the high position of the fire extinguisher box opening. Therefore, the battery with the accident is first transported to the lifting platform 2, and then the lifting platform 2 is controlled to descend to avoid the transfer mechanism 5, and lowered to below the transfer mechanism 5, so that the battery falls on the transfer mechanism 5. Then the fixed units on both sides are fixedly connected to the transfer mechanism 5, so that the transfer mechanism 5 and the lifting platform 2 are connected as a whole. The lifting platform 2 drives the transfer mechanism 5 to the height position of the fire extinguisher box opening, and the transfer mechanism 5 transports the battery with the accident to the inside of the fire extinguisher box, completing the process of automatically handling emergencies.

[0118] Furthermore, the transfer mechanism 5 includes a bracket 52 and a roller 51 .

[0119] The bracket 52 is disposed opposite to the avoidance opening 26 . The roller 51 is rotatably disposed on the bracket 52 . The bracket 52 is provided with a fixing portion 521 for connecting with the telescopic unit 62 .

[0120] Preferably, the telescopic unit 62 includes a telescopic cylinder 621 and a telescopic member 622 .

[0121] The telescopic cylinder 621 is installed on the mounting seat 61 and is arranged near the side of the transfer mechanism 5. The telescopic member 622 is connected to the telescopic part of the telescopic cylinder 621, and is used to move back and forth between the telescopic cylinder 621 and the bracket 52 of the transfer mechanism 5 under the drive of the telescopic cylinder 621. The positioning seat 63 is located between the bracket 52 and the mounting seat 61, and the telescopic member 622 is inserted into the positioning seat 63 and fixed to the bracket 52.

[0122] The telescopic member 622 includes a support plate and a telescopic rod. One side of the support plate is connected to the telescopic cylinder 621 and is perpendicular to the telescopic direction of the telescopic cylinder 621. The telescopic rod is connected to both ends of the other side of the support plate, and the bracket 52 is provided with a fixing hole that matches and connects with the telescopic rod.

[0123] The fixing portion 521 is a fixing hole provided on the bracket 52. The telescopic rod can be inserted into the fixing hole. The fixing hole is provided on the supporting foot.

[0124] The two axial ends of the transfer mechanism 5 are respectively connected to the fixing components 6 .

[0125] The present invention also provides a battery swap station (not shown in the figure) having any of the battery lifting and reversing devices described above.

[0126] The present invention can increase the storage capacity of batteries in the battery exchange station and improve the transportation efficiency of batteries by providing the battery lifting and reversing device, thereby improving the battery exchange efficiency, and can also save floor space.

[0127] The battery swap station includes a battery swap warehouse and a battery warehouse (not shown in the figure). A battery swap platform is provided in the battery swap warehouse. Preferably, the battery warehouse is a container.

[0128] A battery rack and a battery lifting and reversing device are arranged in the battery compartment. The battery lifting and reversing device is arranged adjacent to the battery rack, and the battery lifting and reversing device is arranged opposite to the battery exchange platform.

[0129] Furthermore, the battery swap station further comprises a fire extinguishing box. The fire extinguishing box is arranged adjacent to one side of the frame. An opening is arranged on one side wall of the fire extinguishing box, which is located on one side of the transmission direction of the transfer mechanism.
