Description

Technical Field

[0001] The present invention relates to the technical field of battery replacement for electric vehicles, and in particular to a battery replacement lifting system for replacing power batteries of electric vehicles. Background Art

[0002] Battery swapping and charging are two power supplement modes for electric vehicles. Among them, power battery swapping refers to the centralized storage, centralized charging, and unified distribution of a large number of batteries through centralized charging stations, and the power battery swapping service for electric vehicles in the power swapping station or the integration of battery charging, logistics deployment, and power swapping services.

[0003] Automatic battery swap stations include ground-based and sunken types. In the ground-based type, the vehicle is lifted by a lifting device, and the battery swap device is moved in from the side to replace the power battery. The lifting system also includes a positioning device. Before lifting, the vehicle needs to be accurately positioned so that the vehicle battery is aligned with the specified position to achieve automatic battery swap.

[0004] Existing automatic battery swap stations usually have two modes: parking and driving in and out. Parking requires the electric vehicle to park and drive into the battery swap station, and then drive out after the battery swap is completed; driving in and out requires the electric vehicle to drive into the battery swap station in one direction through the gate control system, and then drive out after the battery swap is completed. The parking mode requires complicated parking steps, which is difficult for novices. The driving in and out mode also requires restrictions on the direction of vehicle entry, which is inconvenient, resulting in inflexible road planning in the battery swap station area.

[0005] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, a battery replacement lifting system for replacing power batteries of electric vehicles is proposed. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1

[0044] The existing battery swap stations have two modes, parking and direct entry and exit, which are inconvenient. In order to realize that vehicles can enter the garage in both directions, freely enter and exit the planned driving route, and adjust the positioning and lifting links during the battery swap process according to the different directions of vehicle entry, embodiment 1 is proposed;

[0045] See also Figure 1-Figure 5 A battery replacement lifting system for replacing electric vehicle power batteries includes a battery replacement station body 100, on which a vehicle track 110 is arranged. The vehicle track 110 is an arched structure for two-way storage of electric vehicles, and four vehicle positioning points 120 arranged in a rectangular shape are arranged in the middle of the vehicle track 110;

[0046] The main body 100 of the battery swap station is also provided with a positioning mechanism 200, a lifting mechanism 300 and a battery swap mechanism 400. When replacing the power battery, the electric vehicle is driven so that the four wheels are respectively located within the four vehicle positioning points 120, and then the electric vehicle is positioned by the positioning mechanism 200, and finally the lifting mechanism 300 and the battery swap mechanism 400 cooperate to lift the electric vehicle to replace the battery;

[0047] The positioning mechanism 200 includes two first positioning components 210 symmetrically arranged along the x-axis and two second positioning components 220 symmetrically arranged along the y-axis. The electric vehicle is positioned on the x-axis and the y-axis based on the vehicle's driving direction by the two first positioning components 210 and the two second positioning components 220 to adapt to the position of the power battery installed by the battery swap mechanism 400;

[0048] The first positioning assembly 210 includes two L-shaped rods 211 symmetrically arranged along the y-axis, the two L-shaped rods 211 are slidably connected to the vehicle track 110, and the two L-shaped rods 211 are both provided with positioning pins 212;

[0049] The four wheel side ends of the electric vehicle are pushed by the four positioning pins 212 respectively displacing along the y-axis, thereby positioning the electric vehicle in the y-axis direction;

[0050] The second positioning assembly 220 includes two rotating shafts 221 symmetrically arranged along the x-axis, the two rotating shafts 221 are rotatably connected to the vehicle track 110, and the two rotating shafts 221 are both provided with a push plate 222;

[0051] The four push plates 222 are rotated along the y-axis to push the four tire treads of the electric vehicle so as to position the electric vehicle in the x-axis direction;

[0052] Auxiliary positioning components 230 are provided in each of the four vehicle positioning points 120. The auxiliary positioning components 230 include a fixing frame 231 provided in the vehicle positioning point 120. A plurality of pulleys 232 are provided on the fixing frame 231. The plurality of pulleys 232 are divided into two groups and are installed on the fixing frame 231 in a V shape.

[0053] In this embodiment, the x, y, and z directions represent left and right, front and back, and up and down, respectively. The vehicle track 110 is arranged along the left and right directions, and vehicles can enter at both ends. Vehicles enter from the left and exit to the right after battery replacement is completed, and vehicles enter from the right and exit to the left after battery replacement is completed.

[0054] When the vehicle drives to the middle of the vehicle track 110, since driving cannot be 100% accurate, it is only necessary to drive the four wheels into the four vehicle positioning points 120 respectively, and then the positioning mechanism 200 will position the vehicle. The V-shaped pulley blocks laid at the four vehicle positioning points 120 are used to support the vehicle to facilitate its displacement and positioning, and a driving device can also be set to drive the pulley blocks to rotate forward and backward, so as to cooperate with the first positioning assembly 210 to push the vehicle in the front and rear directions.

[0055] When positioning the vehicle in the front-to-rear direction, the two L-shaped rods 211 and the two positioning pins 212 on the rear side move forward to push the two front and rear wheels on the rear side, and the two L-shaped rods 211 and the two positioning pins 212 on the front side move backward to push the two front and rear wheels on the front side, and the front and rear two groups of displacements are synchronized, so that the vehicle is pushed to the middle position in the front-to-rear direction to complete the positioning.

[0056] In addition, since the front and rear wheel tracks of a vehicle are usually inconsistent, the front wheel track is generally slightly larger, so that the outer front wheel is subjected to the greatest force when the vehicle turns at high speed. The wider the front wheel track, the smaller the moment of turning. However, the prior art rarely considers the difference in front and rear wheel tracks during positioning. In addition, the front and rear wheel tracks are located at different positions due to the factor of two-way storage. Therefore, the first positioning component 210 also has a corresponding adjustment function.

[0057] After the vehicle is positioned in the front and rear directions, it is positioned in the left and right directions. The two push plates 222 on the right rotate counterclockwise to push the two front wheels to move left, and the two push plates 222 on the left rotate clockwise to push the two rear wheels to move right, thereby pushing the vehicle to position in the left and right directions.

[0058] In addition, since the power battery of an electric vehicle is usually installed near the rear of the vehicle, the left and right positioning of the vehicle is no longer fixed after adding the factor of two-way storage. Therefore, the second positioning component 220 also has a corresponding adjustment function.

[0059] After the vehicle is positioned, the vehicle is lifted by the lifting mechanism 300 and then the battery is replaced by the battery replacement mechanism 400.

[0060] Embodiment 2

[0061] In order to realize positioning according to the front and rear wheel track difference of the reference vehicle in the bidirectional parking mode, a second embodiment is proposed;

[0062] This embodiment is an improvement on the first embodiment. For details, please refer to Figure 1-Figure 4The first positioning assembly 210 further includes a first U-shaped rod 213 slidably arranged in the vehicle track 110 along the y-axis direction, both ends of the first U-shaped rod 213 are provided with first slide grooves 214, and the two L-shaped rods 211 are respectively slidably connected in the two first slide grooves 214, and a first hydraulic cylinder 215 is arranged in the vehicle track 110, and the piston rod of the first hydraulic cylinder 215 is connected to the first U-shaped rod 213;

[0063] The first positioning assembly 210 further includes a first adjusting assembly 216, which is used to respectively adjust the length of the two first sliding grooves 214 extending from the two L-shaped rods 211, so as to adapt to the front and rear wheel track difference of the electric vehicle according to the vehicle's driving direction;

[0064] The first adjustment component 216 includes a first motor 2161 arranged on the first U-shaped rod 213, a first rotating rod 2162 is arranged on the output shaft of the first motor 2161, first connecting rods 2163 are slidably arranged at both ends of the first rotating rod 2162, and first connecting members 2164 are arranged on the two L-shaped rods 211, and the two first connecting rods 2163 are rotatably connected to the two first connecting members 2164 respectively.

[0065] In this embodiment: if the front and rear wheel tracks of the vehicle are consistent, the first motor 2161 connected to the center position of the first rotating rod 2162 controls the first rotating rod 2162 to rotate to the left and right straight direction, so that the two positioning pins 212 are initially in the left and right collinear position.

[0066] According to the driving direction, if the wheelbase on the right side is larger, the first motor 2161 controls the first rotating rod 2162 to rotate counterclockwise, so that Figure 4 The locating pin 212 on the left side moves forward, and the locating pin 212 on the right side moves backward, so that the two locating pins 212 are not collinear in the initial state.

[0067] At this time, the first hydraulic cylinder 215 is controlled Figure 4 The first U-shaped rod 213 in the vehicle body moves forward, driving the two positioning pins 212 to move forward, thereby pushing the vehicle according to the wheelbase difference.

[0068] The upper portion of the first connecting member 2164 is fixed to the L-shaped rod 211 , and the lower portion is a cylinder. The first connecting rods 2163 extending from the left and right ends of the first rotating rod 2162 are rotatably connected to the first connecting member 2164 .

[0069] According to the driving direction, if the wheelbase on the left side is larger, the first motor 2161 controls the first rotating rod 2162 to rotate clockwise by a certain angle. The specific rotation angle can also be adjusted according to the specific wheelbase difference of the vehicle.

[0070] Embodiment 3

[0071] In order to realize positioning of the battery installation position of the vehicle according to the driving direction in the two-way parking mode, a third embodiment is proposed;

[0072] This embodiment is an improvement on the first embodiment. For details, please refer to Figure 1-Figure 8 The second positioning assembly 220 further includes two driving assemblies 223 symmetrically arranged along the y-axis, and the two driving assemblies 223 are respectively used to drive the two push plates 222 to rotate;

[0073] The driving assembly 223 includes a support frame 2231 disposed in the vehicle track 110, the support frame 2231 is provided with a second slide groove 2232, a first push rod 2233 is slidably disposed in the second slide groove 2232, a connecting seat 2234 is provided on the push plate 222, a third slide groove 2235 is provided on the connecting seat 2234, a sliding rod 2236 is provided on the first push rod 2233, and the sliding rod 2236 is slidably connected in the third slide groove 2235;

[0074] The second positioning assembly 220 further includes a second U-shaped rod 224 slidably disposed in the vehicle track 110 along the z-axis direction, and both ends of the second U-shaped rod 224 are provided with fourth slide grooves 225, and second push rods 226 are slidably disposed in the two fourth slide grooves 225;

[0075] The two support frames 2231 are each provided with a fifth slide groove 227, the two fifth slide grooves 227 are respectively connected with the two second slide grooves 2232, the two second push rods 226 are respectively slidably connected in the two fifth slide grooves 227, and a second hydraulic cylinder 228 is provided in the vehicle track 110 along the z-axis direction, and the piston rod of the second hydraulic cylinder 228 is connected with the second U-shaped rod 224;

[0076] The second positioning assembly 220 further includes a second adjusting assembly 229, which is used to respectively adjust the length of the two second push rods 226 extending out of the two fourth slide grooves 225, so as to adapt the installation position of the power battery of the electric vehicle according to the vehicle's driving direction;

[0077] The second adjustment component 229 includes a second motor 2291 arranged on the second U-shaped rod 224, a second rotating rod 2292 is arranged on the output shaft of the second motor 2291, second connecting rods 2293 are slidably arranged at both ends of the second rotating rod 2292, and second connecting members 2294 are arranged on the two second push rods 226, and the two second connecting rods 2293 are rotatably connected to the two second connecting members 2294 respectively.

[0078] In this embodiment, the push plate 222 naturally hangs down under the action of gravity, and the first push rod 2233 hangs down at the bottom of the second slide groove 2232. The initial position of the second push rod 226 does not contact the first push rod 2233 at the lower side.

[0079] When the battery is located near the left side, the vehicle needs to be pushed a little to the right. At this time, the second motor 2291 drives the second rotating rod 2292 to rotate clockwise, so that the initial position of the second push rod 226 on the left side is raised, and the initial position of the second push rod 226 on the right side is relatively low.

[0080] At this time, when the second hydraulic cylinder 228 drives the second U-shaped rod 224 to rise, the second push rod 226 on the left side first touches the first push rod 2233 on the left side, so that the push plate 222 on the left side rotates clockwise to push the vehicle to the right, and then the push plate 222 on the right side rotates counterclockwise to resist the vehicle.

[0081] When the battery is located near the right side, the vehicle needs to be pushed a little to the left, and the second motor 2291 drives the second rotating rod 2292 to rotate counterclockwise to adjust the initial height of the two second push rods 226.

[0082] Embodiment 4

[0083] In order to realize the lifting and battery replacement of the vehicle, as well as the intelligent gate control before entering the battery replacement station, the fourth embodiment is proposed;
