Description

A lifting device for a new energy electric vehicle Technical Field

[0001] This utility model belongs to the field of new energy vehicles, specifically relating to a lifting device for a new energy electric vehicle. Background Technology

[0002] New energy vehicle lifting devices are maintenance and repair equipment specifically designed to adapt to the structural characteristics of new energy vehicles. They are mainly used for the inspection, repair, and replacement of components under the vehicle. With the popularization of new energy vehicles such as electric vehicles and hybrid vehicles, traditional vehicle lifting equipment can no longer fully meet the needs of new energy vehicles, because these vehicles are usually equipped with battery packs, which are often located under the vehicle.

[0003] Utility model patent CN222795070U discloses a hydraulic lifting mechanism including a lifting platform and an outer cylinder and a telescopic unit. The telescopic unit has multiple telescopic components and is connected to the lifting platform. An inlet / outlet oil chamber is provided between the telescopic unit and the outer cylinder. In any two adjacent nested telescopic components, the telescopic component on the outer side is designated as the outer telescopic component, and the telescopic component on the inner side is designated as the inner telescopic component. The outer side of the outer telescopic component forms an outer oil storage chamber, and the inner side of the outer telescopic component and the inner telescopic component form an inner oil storage chamber. The inner oil storage chamber and the outer oil storage chamber are connected. When oil enters the inlet / outlet oil chamber, the outer telescopic component is driven to extend upward, compressing the outer oil storage chamber, causing the oil in the outer oil storage chamber to replenish the inner oil storage chamber. This, in turn, causes the inner oil storage chamber to expand, driving the inner telescopic component to extend upward synchronously. However, although this device can stably lift a car, its protection structure for the vehicle is relatively simple. During the lifting process and at the highest point, the vehicle is at risk of overturning. Therefore, there is an urgent need for a lifting device with high safety for new energy electric vehicles.

[0050] In an embodiment of this utility model, as shown in Figures 1-6, the locking mechanism includes: a locking block 8, a limiting hole 9, a pocket block 10, a top frame 11, a motor 12, a rotating shaft, a first bevel gear, a sealing box 13, a support plate, and threaded rods 14; several locking blocks 8 are connected to one side of the lifting frame 4; several limiting holes 9 are formed in the limiting frame 7; the pocket block 10 slides within the limiting hole 9; the top frame 11 is connected to the top of the limiting frame 7 and the guide frame 3; several motors 12 are connected to one side of the top frame 11, with a rotating shaft connected to the driving end, and several first bevel gears connected to the rotating shaft; the sealing box 13 is connected to one side of the limiting frame 7, the rotating shaft passes through and is movably connected within the sealing box 13, and a support plate is connected within the sealing box 13; several threaded rods 14 are screwed onto one side of the pocket block 10 and movably connected to the support plate.

[0051] In an embodiment of this utility model, as shown in Figures 1-6, the driving mechanism includes: a first hydraulic cylinder 15, a tilting frame 16, and a thrust frame 17; two pairs of the first hydraulic cylinders 15 are hinged to the upper wall inside the base box 1; two pairs of the tilting frames 16 are hinged to the top of the base box 1 and to the bottom of the sliding block 5; the thrust frame 17 is connected between a pair of tilting frames 16, and the telescopic end of the first hydraulic cylinder 15 is hinged to the thrust frame 17.

[0052] In an embodiment of this utility model, as shown in Figures 1-6, it further includes: a tilting servo motor 18 and a limiting tooth 19; a pair of tilting servos 18 are connected to the top of the lifting frame 4; the limiting tooth 19 is movably connected to the top of the lifting frame 4, connected to the drive end of the tilting servo motor 18, and its bottom surface is in sliding contact with the upper surface of the lifting frame 4.

[0053] In an embodiment of this utility model, as shown in Figures 1-6, it further includes: a cover plate, a middle platform 20, and a bracket 21; both of the cover plates are hinged to the top of the base box 1; the middle platform 20 is connected to the middle of the top of the base box 1; and both of the brackets 21 are connected to the top of the base box 1.

[0054] In an embodiment of this utility model, as shown in Figures 1-6, it further includes: a ramp 22; a pair of ramps 22 are respectively connected to both sides of the base box 1.

[0055] In an embodiment of this utility model, as shown in Figures 1-6, it further includes: a second hydraulic cylinder 23 and a clamping plate; a plurality of second hydraulic cylinders 23 are fixedly installed on the top of the top frame 11, and the telescopic end is connected to the clamping plate, and a rubber pad is connected to one side of the clamping plate.

[0056] Implementation process: Before lifting, the vehicle is driven onto the ramp 22 on one side, and then positioned on top of the chassis 1. The tilting servos 18 on both sides then rotate, causing the limiting gear 19 to rotate on the lifting frame 4. After rotating 90 degrees, the limiting gear 19 is positioned at the bottom of the vehicle. Then, the extension end of the first hydraulic cylinder 15 is extended. The thrust frame 17, pushed by the extension end of the first hydraulic cylinder 15, rotates around the hinge point between the tilting frame 16 and the chassis 1, simultaneously lifting the baffle plate. The sliding block 5 then slides within the sliding groove, lifting the lifting frame 4 and causing it to move upwards. During the lifting process, the lifting frame 4 is limited and guided by the guide frame 3. Once the lifting frame 4 reaches the designated position, the drive shaft of the control motor 12 rotates. At this time, the first bevel gear rotates, driving the second bevel gear to rotate, and all the threaded rods 14 rotate. Since the threaded rods 14 are screwed onto one side of the pocket block 10, and the pocket block 10 slides in the limiting hole 9, the pocket block 10 slides out from the inside of the limiting frame 7 and slides out to the bottom of the vehicle chassis. Then, the extension end of the first hydraulic cylinder 15 is slightly shortened, so that the bottom surface of the clamping block 8 contacts the top of the pocket block 10, so that part of the weight of the lifting frame 4 is applied to the pocket block 10, which can reduce the risk of the lifting frame 4 suddenly falling. When the final position of the vehicle is at the highest point, since the limiting frame 7 at the highest point cannot protect the two sides of the vehicle, the extension end of the second hydraulic cylinder 23 is extended to limit the two sides of the vehicle with the clamping plate, thereby improving safety.
