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 with emergency function 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 transportation device, and a fork can be used to pick up and place batteries from a battery rack. In order to prevent accidents with the battery, a fire extinguisher box is usually set up in the battery swap station. When an accident occurs with the battery, the battery is put into the fire extinguisher box using a fork. However, when using the fork of the stacker to pick up and place the battery, the fire extinguisher box needs to be placed in a place where the fork of the stacker can be easily operated. The transport line of the stacker is long, and using the fork to pick up and place the battery has the problems of slow operation speed and large space occupied in the battery swap station. Alternatively, a battery transfer and transportation device is provided on one side of the battery rack for transferring the battery, and the fire extinguisher box is provided adjacent to the battery transfer and transportation device. When an accident occurs with the battery, the battery transfer and transportation device cannot directly push the battery that has an accident into the fire extinguisher box due to the high position of the fire extinguisher box opening. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the technical problems in the prior art that battery transport devices have slow speeds and occupy large areas when transporting batteries with accidents.

[0005] In order to solve the above technical problems, the first aspect of the present invention discloses a battery lifting and reversing device with emergency function, comprising:

[0006] Lifting platform, used to transfer batteries horizontally;

[0007] A frame, in which the lifting platform is arranged to be movable up and down;

[0008] The transfer mechanism is arranged at the bottom of the frame and is located below the lifting platform. It can be connected to the lifting platform for transmission. The transfer mechanism and the lifting platform are detachably connected.

[0009] The transfer mechanism of the present invention is located below the lifting platform and can be connected to the lifting platform for transfer. The transfer mechanism is detachably connected to the lifting platform; when an accident occurs to the battery, the transfer mechanism is connected to the lifting platform and can be integrated with the lifting platform, enabling the transfer mechanism to move up and down opposite to the opening of the fire box, and capable of transporting the accident-occurring battery to the fire box. The battery lifting and reversing device of the present invention has a compact structure, small floor area, and low cost, and can automatically and quickly transfer the battery into the fire box when an accident occurs to the battery.

[0010] Furthermore, it also includes,

[0011] A fixing component, which is telescopically arranged on the lifting platform;

[0012] The fixing component is detachably connected to the transfer mechanism.

[0013] Furthermore, the fixing component is arranged on the bottom wall of the lifting platform, outside both ends in the transmission direction of the transfer mechanism.

[0014] Furthermore, the fixing component includes,

[0015] A mounting seat, which is arranged on the bottom wall of the lifting platform;

[0016] A telescopic unit, which is telescopically arranged on the mounting seat and used for detachably connecting to the transfer mechanism.

[0017] Furthermore, the fixing component also includes,

[0018] A positioning seat, which is arranged on the bottom wall of the lifting platform, and the telescopic unit is telescopically inserted into the positioning seat.

[0019] Furthermore, an avoidance opening is provided on the lifting platform for avoiding the transfer mechanism, so that the bearing surface of the transfer mechanism is higher than the bearing surface of the lifting platform;

[0020] The fixing component is arranged on the lifting platform around the avoidance opening.

[0021] Furthermore, the transfer mechanism includes,

[0022] A bracket, which is arranged opposite to the avoidance opening;

[0023] Rollers, which are rotatably arranged on the bracket at intervals, and a fixing part is provided on the bracket for connecting to the telescopic unit.

[0024] Furthermore, a transmission mechanism is provided on the lifting platform, and the transmission direction of the transmission mechanism is perpendicular to the transmission direction of the transfer mechanism;

[0025] The fixing assembly is arranged on the lifting platforms at both sides of the roller axial direction, and the fixing part is arranged on both ends of the bracket along the axial direction of the roller.

[0026] Furthermore, it also includes a lifting mechanism installed on the lifting platform, which is used to cooperate with the frame to drive the lifting platform to move up and down.

[0027] A second aspect of the present invention discloses a battery swap station having any of the above-mentioned battery lifting and reversing devices with emergency functions.

[0028] Furthermore, the battery swap station also includes:

[0029] A fire extinguishing box, disposed adjacent to one side of the frame;

[0030] An opening is provided on one side wall of the fire fighting box, which is located on one side of the transmission direction of the transfer mechanism.

[0047] like Figures 1 to 6 As shown, the battery lifting and reversing device with emergency function described in the present invention includes a lifting platform 2, a frame 1 and a transfer mechanism 5.

[0048] The lifting platform 2 is used to transfer batteries in a horizontal direction. The lifting platform 2 is arranged in the frame 1 so as to be movable up and down. The transfer mechanism 5 is arranged at the bottom of the frame 1. The transfer mechanism 5 is located below the lifting platform 2 and can be connected to the lifting platform 2 for transmission. The transfer mechanism 5 is detachably connected to the lifting platform 2.

[0049] The transfer mechanism 5 of the present invention is located below the lifting platform 2 and can be connected to the lifting platform 2 for transmission. The transfer mechanism 5 is detachably connected to the lifting platform 2. When an accident occurs to the battery, the transfer mechanism 5 is connected to the lifting platform 2 and can be connected to the lifting platform 2 as a whole, so that the transfer mechanism 5 can move up and down to be opposite to the opening of the fire extinguisher box, and can transport the battery that has an accident to the fire extinguisher box. The battery lifting and reversing device of the present invention has a compact structure, small footprint, and low cost. It can also automatically and quickly transfer the battery to the fire extinguisher box when an accident occurs to the battery.

[0050] The battery lifting and reversing device can be applied to a battery swap station and arranged in a battery compartment of the battery swap station. The battery reversing device can be arranged adjacent to a battery rack and used for taking and placing batteries on the battery rack.

[0051] The lifting platform 2 and the transfer mechanism 5 are connected for transmission in the horizontal direction, and the batteries on the lifting platform 2 can be transferred to the transfer mechanism 5, and then transferred to the battery replacement device through other external transmission mechanisms to replace the batteries for the electric vehicle. Alternatively, the batteries on the transfer mechanism 5 can be transferred to the lifting platform 2, and the lifting platform 2 can be used to place the batteries on the battery rack.

[0052] As Figures 2 to 4 shown, the battery lifting and reversing device further includes a fixing component 6. The fixing component 6 is telescopically arranged on the lifting platform 2. The fixing component 6 is detachably connected to the transfer mechanism 5.

[0053] By providing the fixing component 6 in the present invention, when the battery is being transported normally, the fixing component 6 is not connected to the transfer mechanism 5; when an accident occurs to the battery and it is necessary to transport the battery into the fire 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 and the lifting platform 2 are joined into a whole, move up and down with the lifting platform 2 to be opposite to the opening of the fire box, and are transported into the fire box by the transfer mechanism 5.

[0054] The fixing component 6 is arranged on the bottom wall of the lifting platform 2, and is respectively located outside both ends in the transmission direction of the transfer mechanism 5.

[0055] The fixing component 6 includes a mounting seat 61 and a telescopic unit 62.

[0056] 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 for detachably connecting to the transfer mechanism 5. The telescopic unit 62 is a controllable automatic telescopic unit 62.

[0057] Further, the fixing component 6 further includes a positioning seat 63. The positioning seat 63 is arranged on the bottom wall of the lifting platform 2, and the telescopic unit 62 is telescopically inserted into the positioning seat 63.

[0058] By providing the positioning seat 63 in the present invention, the telescopic unit 62 is inserted into the positioning seat 63, which can keep the telescopic direction of the telescopic unit 62 stable and ensure quick and accurate connection with the transfer mechanism 5.

[0059] An avoidance opening 26 is provided on the lifting platform 2 for avoiding 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 component 6 is arranged on the lifting platform 2 outside the periphery of the avoidance opening 26.

[0060] When an accident occurs to the battery, due to the relatively high position of the opening of the fire box, the transfer mechanism 5 cannot directly push the accident - occurred battery into the fire box. Therefore, first, the accident - occurred battery is conveyed to the lifting platform 2, and then the lifting platform 2 is controlled to descend, avoiding the transfer mechanism 5, and descending below the transfer mechanism 5 so that the battery falls on the transfer mechanism 5. Then the fixing units on both sides are fixedly connected to the transfer mechanism 5, and further, the transfer mechanism 5 and the lifting platform 2 are integrated. The lifting platform 2 drives the transfer mechanism 5 to the height position of the opening of the fire box, and the transfer mechanism 5 conveys the accident - occurred battery into the fire box, completing the process of automatically handling emergencies.

[0061] Further, the transfer mechanism 5 includes a bracket 52 and rollers 51.

[0062] The bracket 52 is disposed opposite to the avoidance opening 26. The rollers 51 are rotatably arranged at intervals on the bracket 52, and a fixing portion 521 is provided on the bracket 52 for connecting with the telescopic unit 62.

[0063] Preferably, the telescopic unit 62 includes a telescopic cylinder 621 and a telescopic member 622.

[0064] The telescopic cylinder 621 is installed on the mounting seat 61, disposed on the side close to 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 passes through the positioning seat 63 and is fixed to the bracket 52.

[0065] 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, perpendicular to the telescopic direction of the telescopic cylinder 621. The telescopic rod is respectively connected to both ends of the other side of the support plate, and fixing holes are provided on the bracket 52 for mating connection therewith.

[0066] The fixing portion 521 is a fixing hole provided on the bracket 52. The telescopic rod can be inserted into the fixing hole.

[0067] Both axial ends of the transfer mechanism 5 are respectively connected to the fixing assembly 6.

[0068] The bracket 52 includes a rectangular frame and four support feet. The support feet are provided on the bottom walls of the four right - angles of the rectangular frame. The fixing holes are provided on the outer sides of the support feet.

[0069] The roller 51 is arranged within the rectangular frame, and the axial direction of the roller 51 extends along the length direction of the rectangular frame.

[0070] Furthermore, the battery lifting and reversing device further includes a transition transmission unit 53, which is arranged at the bottom of the frame 1, can be fixed on the ground, and is located on both axial sides of the transfer mechanism 5. The transmission direction of the transition transmission unit 53 is the same as that of the transfer mechanism 5.

[0071] The transition transmission unit 53 includes a support frame and transition rollers arranged on the upper part of the support frame. The transition rollers are arranged in parallel with and at the same height as the roller 51. An avoidance groove 27 is provided on the lifting platform 2 for moving downward to avoid the transition rollers, so that the bearing surface of the transition rollers is higher than the plane of the lifting platform 2.

[0072] A transmission mechanism 4 is provided on the lifting platform 2, and the transmission direction of the transmission mechanism 4 is perpendicular to the transmission direction of the transfer mechanism 5.

[0073] The fixing assembly 6 is arranged on the lifting platform 2 on both axial sides of the roller 51. The fixing part 521 is arranged at both axial ends of the bracket 52 along the roller 51.

[0074] As Figures 2 to 6 shown, the battery conversion and reversing device further includes a lifting mechanism 3, which 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 together.

[0075] The lifting mechanism 3 includes a driving unit 31 and a moving unit.

[0076] As an implementation scheme, the moving unit is rotatably arranged on the bottom wall of the lifting platform 2. The moving unit meshes with the frame 1. The driving unit 31 is arranged on the bottom wall of the lifting platform 2. The driving unit 31 is connected to the moving unit and is used to drive the moving unit to rotate so as to move on the frame 1.

[0077] In the present invention, by arranging the moving unit and the driving unit 31 of the lifting mechanism 3 on the bottom wall of the lifting platform 2, the space above the lifting platform 2 is not occupied, so that the lifting platform 2 can move to the uppermost part of the frame 1 to pick up and place the batteries on the uppermost layer of the battery rack, reducing the space occupied by the battery conversion and reversing device in the battery swapping station, and not occupying the space above the lifting platform 2, which facilitates the connection and transmission between the lifting platform 2 and other transportation mechanisms.

[0078] The moving unit includes a first rotating shaft 32 and a first gear 321.

[0079] The first rotating shaft 32 is rotatably arranged on the bottom wall of the lifting platform 2 and is connected to the driving unit 31. The first gear 321 is arranged on the first rotating shaft 32 and meshes with one side of the frame 1.

[0080] The driving unit 31 is connected to the first rotating shaft 32 and is used to drive the first rotating shaft 32 to rotate in the positive and negative directions around the axis, so that the first gear 321 moves up and down along the frame 1, thereby driving the lifting platform 2 to move up and down.

[0081] When the driving unit 31 rotates forward, it drives the first rotating shaft 32 to rotate forward, driving the first gear 321 to move upward on the frame 1, so that the lifting platform 2 moves upward on the frame 1. When the driving unit 31 rotates reversely, it drives the first rotating shaft 32 to rotate reversely, driving the first gear 321 to move downward on the frame 1, thereby driving the lifting platform 2 to move downward on the frame 1.

[0098] By providing bevel gear transmission in the present invention, the lifting mechanism operates smoothly during work, and has less noise and vibration during high-speed operation.

[0099] Further, the lifting mechanism 3 further includes a first bearing seat, a second bearing seat and a third bearing seat.

[0100] The lifting mechanism 3 further includes a first bearing seat.

[0111] In the present invention, by providing the transmission mechanism 4 on the lifting platform 2, the battery can be transmitted in the horizontal direction. A telescopic blocking mechanism 22 is provided on the outer 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 at one end of the lifting platform 2 retracts and does not protrude from the surface of the lifting platform 2, which can ensure the smooth passage of the battery. The blocking mechanism 22 at the other end of the lifting platform 2 protrudes, which can prevent the battery from continuing to move outwards and prevent the battery from falling off.
