Description
Technical Field
[0001] The utility model relates to a power exchange and maintenance platform for new energy vehicles, belonging to the technical field of power exchange and maintenance of new energy vehicles. Background Art
[0002] As a new type of transportation vehicle, a new energy vehicle uses a storage battery as an energy storage power source. It provides electrical energy from the battery to drive the motor to operate, thereby driving the vehicle to travel. It has advantages such as zero emissions and a wide range of energy sources. It is an important means to alleviate the shortage of oil resources and the serious urban air pollution, and is an effective carrier to promote the transformation of the transportation development mode and the promotion of energy conservation and emission reduction work.
[0003] After a new energy vehicle has been used for a period of time, in order to ensure the normal use of the vehicle and eliminate some potential safety hazards, it is necessary to regularly maintain and repair the vehicle. When the vehicle is being maintained, it is necessary to check and detect the chassis of the vehicle, which requires the vehicle to be lifted to a certain height. Generally, the vehicle is lifted as a whole by hoisting. This method has relatively large safety hazards. Of course, there is also a method of using a maintenance platform to drive the vehicle onto the platform for maintenance. However, the existing platforms mostly play a role in supporting the vehicle. Whether the front and rear positions of the vehicle are in place and whether the vehicle is centered depends entirely on the driving skills of the driver. If the vehicle is not in place, the positions to be observed and detected on the vehicle chassis cannot be fully displayed through the maintenance openings on the platform.
[0004] There is also a problem with new energy vehicles, which is the battery endurance problem. Especially when driving long distances, the battery endurance mileage of new energy vehicles is short, the charging time is long, and the charging facilities are few. Although the government and enterprises are making great efforts to improve the supporting charging infrastructure industry for electric vehicles and the charging facilities are gradually increasing, it is still difficult to solve the problem of charging and energy replenishment. This situation is particularly prominent during holidays. Then, the fundamental method to overcome the development bottleneck of new energy vehicles is rapid power exchange. Replacing the battery has become one of the rapid energy replenishment methods for new energy vehicles. When the battery decays to the point where it needs to be replaced, the battery is replaced in a timely manner. The battery of a new energy vehicle is basically installed on the chassis between the front and rear wheels of the vehicle. Similarly, the new energy vehicle also needs to be lifted to a certain height to raise the battery position for convenient battery replacement. Of course, a platform can also be selected for the power exchange of new energy vehicles. However, the battery replacement has relatively strict requirements on the battery position. If the front and rear positions and left and right positions of the vehicle are not in place, it is difficult to take out and place the battery, and it is also easy to damage the vehicle. If the vehicle position is adjusted manually, the efficiency is obviously very low. Therefore, it is necessary to improve the existing platform, otherwise it cannot meet the requirements of power exchange and maintenance of new energy vehicles. Summary of the Invention
[0005] The utility model aims at the deficiencies of the existing technology and provides a power exchange and maintenance platform for new energy vehicles.
[0006] The technical solution of the present utility model to solve the above technical problems is as follows: A new energy vehicle battery swapping and maintenance platform, including a platform panel, a pair of front wheel positioning mechanisms and a pair of rear wheel positioning mechanisms arranged on the platform panel. The front wheel positioning mechanisms and the rear wheel positioning mechanisms can position the front, rear, left and right positions of the vehicle driving onto the platform panel. There is an opening on the platform panel, and a pair of the front wheel positioning mechanisms are symmetrically arranged on both sides of the front part of the opening, and a pair of the rear wheel positioning mechanisms are symmetrically arranged on both sides of the rear part of the opening.
[0007] The beneficial effects of the present utility model are: By adjusting and positioning the front and rear positions and the left and right positions of the vehicle driving onto the platform panel through the front wheel positioning mechanisms and the rear wheel positioning mechanisms, it is ensured that the front, rear, left and right positions of the vehicle on the platform panel can meet the position requirements for maintenance, repair and battery swapping. This is not only beneficial to the maintenance and repair of the vehicle, but also convenient for taking and placing the battery when swapping the battery, and will not damage the vehicle.
[0008] On the basis of the above technical solution, the present utility model can also be improved as follows.
[0009] Further, the front wheel positioning mechanism includes a front roller row assembly arranged on the platform panel for supporting the front wheels and a front wheel left-right pushing assembly for adjusting the left and right positions of the new energy vehicle. The front roller row assembly is of a concave structure; and / or the rear wheel positioning mechanism includes a rear roller row arranged on the platform panel for supporting the rear wheels and a rear wheel left-right pushing assembly for adjusting the left and right positions of the new energy vehicle.
[0010] The beneficial effects of adopting the above further solution are that after the vehicle drives onto the platform, the front roller row assembly of the concave structure can limit the front and rear positions of the front wheels of the vehicle, and the rear roller row can support and position the rear wheels of the vehicle. After the front and rear positions of the vehicle are positioned, the left and right positions of the vehicle can also be adjusted through the front wheel left-right pushing assembly and the rear wheel left-right pushing assembly, so that the vehicle can be centered, thus meeting the requirements of the vehicle position for battery swapping and maintenance.
[0011] Further, the front roller row assembly includes a first front roller row and a second front roller row. The first front roller row is inclined with the front end higher and the rear end lower, and the second front roller row is inclined with the front end lower and the rear end higher. A concave structure is formed between the first front roller row and the second front roller row, and the cross-section of the concave structure is a V-shaped groove.
[0012] The beneficial effects of adopting the above further solution are that after the vehicle drives onto the platform panel, as the vehicle moves forward, the front wheels of the vehicle will enter the front roller row assembly, and the front wheels are positioned and in place through the V-shaped groove, thus ensuring that the front and rear positions of the vehicle are in place.
[0013] Further, the left - right shifting assembly of the front wheels includes a front pushing plate acting on the front wheels and a front pushing driving cylinder for driving the front pushing plate to move left and right. The cylinder block of the front pushing driving cylinder is arranged on the platform panel, and its piston rod is connected to the front pushing plate; and / or the left - right shifting assembly of the rear wheels includes a rear pushing plate acting on the rear wheels and a rear pushing driving cylinder for driving the rear pushing plate to move left and right. The cylinder block of the rear pushing driving cylinder is arranged on the platform panel, and its piston rod is connected to the rear pushing plate.
[0014] The beneficial effect of adopting the above - mentioned further solution is that the left - right shifting assembly of the rear wheels can center the vehicle that has reached the front - rear position. Specifically, through the action of the driving cylinder, the pushing plate is driven to act, and the pushing plate acts on the wheels, thereby adjusting the acting position of the vehicle. Since the wheels are supported on the roller rows, the axis of the rear roller row is arranged in the front - rear direction, and it is more convenient for the vehicle to be adjusted in the left - right position. Although the axis of the front roller row is not arranged in the standard front - rear direction due to the existence of the concave structure, it is also very convenient to adjust the front wheels. The front pushing plate and the rear pushing plate can both be arranged on the outer sides of the front wheels and the rear wheels.
[0015] Further, a vehicle lifting mechanism for lifting new energy vehicles is also provided at the opening.
[0016] The beneficial effect of adopting the above - mentioned further solution is that when the vehicle drives onto the platform, if it is necessary to further raise the position of the vehicle, the vehicle can be lifted by the vehicle lifting mechanism. For example, when replacing the battery, it is necessary for the vehicle to meet the battery - replacement position to facilitate the removal and installation of the battery, and the vehicle can be lifted to the required height by the vehicle lifting mechanism.
[0017] Further, at least one vehicle lifting mechanism is provided. The vehicle lifting mechanism includes a lifting frame for the lifting of new energy vehicles and a lifting driving mechanism for driving the lifting frame to act. The lifting frame is arranged on the bearing frame through the lifting driving mechanism, and the bearing frame is arranged on the track through a front - rear moving mechanism. The track is arranged along the front - rear direction at the bottom of the platform panel or below the platform panel.
[0018] The beneficial effect of adopting the above - mentioned further solution is that two vehicle lifting mechanisms can be provided. The vehicle can be lifted through the lifting surface or lifting points on the lifting frame. Not only can it lift the vehicle, but the lifting mechanism can also be adjusted back and forth along the track so that the position of the lifting surface or lifting points of the lifting frame can correspond to the lifting position of the vehicle, and it can realize the lifting of multiple - model vehicles.
[0019] Further, the front - rear moving mechanism includes a driving motor, a driving gear, and a rack engaged with the driving gear. The rack is arranged on the track, the driving gear is arranged on the output shaft of the driving motor, and the driving motor is arranged on the bearing frame.
[0020] The beneficial effect of adopting the above further scheme is that the drive motor is activated to drive the drive gear to rotate, and the drive gear is engaged with the rack to realize the forward and backward movement of the carrier on the track. The gear and rack are engaged and transmitted with good stability, low noise and high transmission efficiency.
[0021] Further, the lifting drive mechanism includes a pair of fork-shaped arm assemblies and a lifting drive mechanism, a first arm and a second arm are hinged in the middle of the fork-shaped arm assembly, the bottom end of the first arm is hinged to the bearing frame, and the top end is connected to the lifting frame in a sliding or rolling manner, and the bottom end of the second arm is connected to the bearing frame in a sliding or rolling manner, and the top end is hinged to the lifting frame;

The transmission screw is rotatably arranged on the supporting frame. The screw nut is connected to the bottom ends of a pair of the second support arms.
[0023] The beneficial effect of adopting the above further solution is that the lifting motor is activated to drive the transmission screw to rotate, and the screw nut can move along the axis direction of the screw, thereby driving the bottom end of the second arm to move closer to or away from the first arm, thereby realizing the lifting and lowering action of the lifting frame, and realizing the lifting and lowering action of the vehicle. The lifting drive mechanism has a compact structure and can realize the vertical lifting of the lifting frame. While ensuring that the lifting height requirement is met, the required installation space is still small, making the lifting drive mechanism more widely used.
[0024] Furthermore, a safety enclosure structure is provided on the platform panel at the edge of the opening.
[0025] The beneficial effect of adopting the above further solution is that the safety enclosure structure includes a plurality of blocking rollers, and the blocking rollers are rotatably arranged on the platform panel. Specifically, the two ends of the blocking rollers are respectively arranged on the platform panel through bearing seats. The safety enclosure structure can provide safety protection for the edge of the opening position to prevent vehicles from entering the opening position.
[0026] Furthermore, the surface of the platform panel is made of an anti-slip plate, and the anti-slip plate is provided with anti-slip grooves.
[0027] The beneficial effect of adopting the above further solution is that the anti-skid plate can play an anti-skid role, further ensuring the safety of the vehicle on the platform.

Detailed implementation mode
[0043] The principles and features of the present utility model will be described below in conjunction with examples. The examples are only used to explain the present utility model and are not intended to limit the scope of the present utility model.
[0044] As Figures 1-8 shown, a new energy vehicle battery swapping and maintenance platform includes a platform panel 1, a pair of front-wheel positioning mechanisms 2 and a pair of rear-wheel positioning mechanisms 3 provided on the platform panel 1. The front-wheel positioning mechanism 2 and the rear-wheel positioning mechanism 3 can position the front, rear, left, and right positions of the vehicle driving onto the platform panel 1. An opening 101 is provided on the platform panel 1. A pair of the front-wheel positioning mechanisms 2 are symmetrically arranged on both sides of the front part of the opening 101, and a pair of the rear-wheel positioning mechanisms 3 are symmetrically arranged on both sides of the rear part of the opening 101.
[0045] The front-wheel positioning mechanism 2 includes a front roller row assembly provided on the platform panel 1 for supporting the front wheels and a front-wheel left-right pushing assembly for adjusting the left-right position of the new energy vehicle. The front roller row assembly has a concave structure; and / or the rear-wheel positioning mechanism 3 includes a rear roller row 301 provided on the platform panel 1 for supporting the rear wheels and a rear-wheel left-right pushing assembly for adjusting the left-right position of the new energy vehicle. After the vehicle drives onto the platform, the front roller row assembly with a concave structure can limit the front and rear positions of the front wheels of the vehicle, and the rear roller row 301 can support and position the rear wheels of the vehicle. After the front and rear positions of the vehicle are positioned, the left-right position of the vehicle can also be adjusted through the front-wheel left-right pushing assembly and the rear-wheel left-right pushing assembly, so that the vehicle can be centered, thus meeting the requirements for the vehicle position in battery swapping and maintenance.
[0046] The front roller row assembly includes a first front roller row 201 and a second front roller row 202. The first front roller row 201 is inclined with the front end higher and the rear end lower. The second front roller row 202 is inclined with the front end lower and the rear end higher. The concave structure is formed between the first front roller row 201 and the second front roller row 202, and the cross-section of the concave structure is a V-shaped groove. After the vehicle drives onto the platform panel 1, as the vehicle moves forward, the front wheels of the vehicle will enter the front roller row assembly. The front wheels are positioned and in place through the V-shaped groove, thereby ensuring that the front and rear positions of the vehicle are in place.
[0047] The front wheel left-right shifting assembly includes a front push plate 203 acting on the front wheels and a front push driving cylinder 204 for driving the front push plate 203 to move left and right. The cylinder block of the front push driving cylinder 204 is arranged on the platform panel 1, and its piston rod is connected to the front push plate 203; and / or the rear wheel left-right shifting assembly includes a rear push plate 302 acting on the rear wheels and a rear push driving cylinder 303 for driving the rear push plate 302 to move left and right. The cylinder block of the rear push driving cylinder 303 is arranged on the platform panel 1, and its piston rod is connected to the rear push plate 302. The vehicle that has reached the front and rear positions can be centered by the rear wheel left-right shifting assembly. Specifically, by the action of the driving cylinder, the push plate is driven to act, and the push plate acts on the wheels, thereby adjusting the acting position of the vehicle. Since the wheels are supported on the roller row and the axis of the rear roller row 301 is arranged front and rear, it is convenient to adjust the vehicle left and right. Although the axis of the front roller row is not in a standard front and rear position due to the existence of the concave structure, it is also very convenient to adjust the front wheels. The front push plate 203 and the rear push plate 302 can both be arranged on the outer sides of the front wheels and the rear wheels.
[0048] A vehicle lifting mechanism 7 for lifting new energy vehicles is also provided at the opening 101. When the vehicle drives onto the platform, if it is necessary to further raise the position of the vehicle, the vehicle can be lifted by the vehicle lifting mechanism 7. For example, when replacing the battery, it is required that the vehicle meets the battery replacement position for easy battery removal and installation, and the vehicle can be lifted to the required height by the vehicle lifting mechanism 7.
[0049] At least one vehicle lifting mechanism 7 is provided. The vehicle lifting mechanism 7 includes a lifting frame 701 for lifting new energy vehicles and a lifting drive mechanism for driving the lifting frame 701 to move. The lifting frame 701 is arranged on a bearing frame 702 through the lifting drive mechanism. The bearing frame 702 is arranged on a track 703 through a front-back moving mechanism. The track 703 is arranged at the bottom of or below the platform panel 1 in the front-back direction. Two vehicle lifting mechanisms 7 can be provided. The vehicle can be lifted through the lifting surface or lifting points on the lifting frame 701. Not only can it lift the vehicle, but the lifting mechanism can also be adjusted back and forth along the track 703 so that the position of the lifting surface or lifting points of the lifting frame 701 can correspond to the lifting position of the vehicle, and the lifting of multiple vehicle models can be achieved.
[0050] Two vehicle lifting mechanisms 7 are provided, namely a front lifting mechanism and a rear lifting mechanism.
[0051] The front-back moving mechanism includes a driving motor 706, a driving gear 705, and a rack 704 meshing with the driving gear 705. The rack 704 is arranged on the track 703. The driving gear 705 is arranged on the output shaft of the driving motor 706. The driving motor 706 is arranged on the bearing frame 702. When the driving motor 706 operates, it drives the driving gear 705 to rotate. The driving gear 705 meshes with the rack 704, realizing the front-back movement of the bearing frame 702 on the track 703. The gear-rack 704 meshing transmission has good smoothness, low noise, and high transmission efficiency.
[0052] The lifting drive mechanism includes a pair of fork-shaped arm assemblies and a lifting drive mechanism. The middle parts of the fork-shaped arm assemblies are hinged with a first arm 707 and a second arm 708. The bottom end of the first arm 707 is hinged with the bearing frame 702, and the top end is slidably or rollably connected to the lifting frame 701. For example, the top end is matched with the raceway on the lifting frame 701 through rollers. The bottom end of the second arm 708 is slidably or rollably connected to the bearing frame 702, and the top end is hinged to the lifting frame 701.
[0053] The lifting drive mechanism includes a lifting motor 709, a transmission lead screw 710 and a lead screw nut 711. The lifting motor 709 is arranged on the carrier 702. The transmission lead screw 710 is rotatably arranged on the carrier 702. The lead screw nut 711 is connected to the bottom ends of a pair of second arms 708. Specifically, the bottom ends of the pair of second arms 708 are connected to the lead screw nut 711 through a connecting rod. The lifting motor 709 is actuated to drive the transmission lead screw 710 to rotate. The lead screw nut 711 can move along the axis of the lead screw, thereby driving the bottom end of the second arm 708 to move in a direction close to or away from the first arm 707, thereby realizing the lifting and lowering of the lifting frame 701 and the lifting and lowering of the vehicle. The lifting drive mechanism has a compact structure and can realize the vertical lifting of the lifting frame 701. While ensuring that the lifting height requirement is met, the required installation space is still small, so that the application occasions of the lifting drive mechanism are more extensive.
[0054] A safety enclosure structure 4 is also provided on the platform panel 1 at the edge of the opening 101. The safety enclosure structure 4 includes a plurality of blocking rollers, which are rotatably arranged on the platform panel 1. Specifically, both ends of the blocking rollers are respectively arranged on the platform panel 1 through bearing seats. The safety enclosure structure 4 can provide safety protection for the edge of the opening 101 to prevent vehicles from entering the opening 101.
[0055] The surface of the platform panel 1 is made of an anti-skid plate, and the anti-skid plate is provided with anti-skid patterns. The anti-skid plate can play an anti-skid role, further ensuring the safety of the vehicle on the platform.
[0056] A receiving ramp is provided on the entrance side of the platform panel 1. The receiving ramp facilitates vehicles to enter the platform smoothly.
[0057] A front baffle 8 is also provided on the platform panel 1 in front of the front wheel alignment mechanism 2. This can further ensure that the vehicle drives into the front and rear positions of the platform, so that the front wheels of the vehicle can accurately reach the front wheel alignment mechanism.
[0058] The entrance of the platform panel 1 is also provided with a lifting limit column 6. When the platform can be entered, the lifting limit column 6 is lowered, and the vehicle can smoothly enter the platform. When there is a vehicle on the platform, the lifting limit column 6 can be raised to prevent the next vehicle from entering by mistake.
[0059] The lifting limit post 6 descends, and the new energy vehicle can drive onto the platform panel 1. When the front wheels of the vehicle enter the V-shaped grooves of the front roller row and the vehicle stops, the rear roller row 301 supports the rear wheels of the vehicle at this time. The front push plate 203 acts on the front wheels of the vehicle under the action of the front drive cylinder, and the rear push plate 302 acts on the rear wheels of the vehicle under the action of the rear drive cylinder to adjust the left and right positions of the stopped vehicle. After the vehicle is centered, the vehicle chassis can be observed, inspected, maintained, and battery replaced at the opening 101 position. Of course, if it is necessary to lift the vehicle to a certain height before maintenance and battery replacement, the vehicle lifting mechanism 7 can be used to control the lifting of the vehicle, so as to achieve the purpose of maintaining and replacing the battery at the required height. The utility model adjusts and positions the front and rear positions and left and right positions of the vehicle driving onto the platform panel 1 through the front wheel positioning mechanism 2 and the rear wheel positioning mechanism 3, so as to ensure that the front, rear, left, and right positions of the vehicle on the platform panel 1 can meet the position requirements for maintenance, repair, and battery replacement, which is not only conducive to the maintenance and repair of the vehicle, but also convenient for taking and placing the battery when replacing the battery and will not damage the vehicle.
