Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, specifically an electric actuator for a compact battery swapping station. Background Technology

[0002] With the widespread application of new energy vehicles, battery swapping stations have become an important infrastructure for rapid energy replenishment. During the battery swapping process, the electric push rod is a key component for achieving precise lifting, docking, and separation of the power battery. Most existing electric push rods for battery swapping use a traditional motor drive combined with a lead screw lifting structure.

[0003] While existing electric push rods for battery swapping can perform basic lifting and lowering actions, they often suffer from problems such as large impacts, insufficient buffering, and concentrated force on the mechanism during the pushing and pulling of batteries. These issues can easily lead to wear and tear on the device, decreased accuracy, and even shorten the overall service life of the equipment.

[0004] Therefore, it is necessary to design a compact electric actuator for battery swapping stations to solve the above problems. Utility Model Content

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3 This utility model provides a compact electric push rod for a battery swapping station, including an equipment box 1. A servo motor 3 and a fixed cylinder 4 are fixedly connected to the top of the equipment box 1, and a rotating shaft 9 is fixedly connected to the output shaft of the servo motor 3. A cylindrical groove is formed inside the fixed cylinder 4. A screw 10 is rotatably connected to the bottom of the inner cavity of the equipment box 1, and a lifting column 6 is threadedly inserted into the top of the screw 10. A first connecting block 5 is fixedly connected to the top of the lifting column 6. A first gear 11 and a second gear 12 are threadedly sleeved at the bottom ends of the rotating shaft 9 and the screw 10, respectively, and the first gear 11 and the second gear 12 mesh with each other. A buffer zone 18 and a sliding zone 19 are formed on both sides of the interior of the fixed cylinder 4, and a dividing block 16 is fixedly connected between each buffer zone 18 and sliding zone 19 on the same side. A notch is formed on an adjacent side of each of the two sliding zones 19, and a second connecting block 14 is fixedly connected to both sides of the bottom of the lifting column 6, and the two second connecting blocks 14 are slidably inserted into the notches. Each of the second connecting blocks 14 has a lifting block 15 fixedly connected to one side, and a connecting column 20 fixedly connected to the top of the lifting block 15. A honeycomb plate 13 is fixedly connected to the top of the connecting column 20. Filling ports 7 are opened on both sides of the fixed cylinder 4. By turning on the servo motor 3 and rotating the rotating shaft 9, the first gear 11 drives the second gear 12 to decelerate. By rotating the screw 10, the lifting column 6 can slowly rise and fall inside the fixed cylinder 4, thereby reducing the impact of rapid extension and retraction of the lifting column 6 on the fixed cylinder 4 itself. At the same time, when the lifting column 6 rises and falls, the lifting blocks 15 inside the two sliding areas 19 will simultaneously drive the two honeycomb plates 13 to slide inside the two buffer zones 18 through the two connecting columns 20. When oily liquid is filled into the two buffer zones 18 through the two filling ports 7, the sliding of the two honeycomb plates 13 uses the oily liquid to buffer the movement, thereby further reducing the possibility of the device being impacted and improving the service life of the device.

[0021] In order to buffer the lifting and lowering of the lifting column 6 by using the sliding of the two honeycomb panels 13 inside the two buffer zones 18 respectively, the number of the honeycomb panels 13 is two, and the two honeycomb panels 13 are slidably disposed inside the two buffer zones 18 respectively, with the outer surfaces of the two honeycomb panels 13 respectively in contact with the inner walls of the two buffer zones 18.

[0022] To facilitate the reciprocating sliding of the honeycomb panel 13, and to seal the sliding insertion of the connecting post 20 at the dividing block 16, there are two connecting posts 20, and the two connecting posts 20 are slidably inserted into the interior of the two dividing blocks 16 respectively. The inner walls of the two dividing blocks 16 are each embedded with two sealing rings 17, and the two sealing rings 17 on the same side are respectively attached to the outer surface of the corresponding connecting post 20.

[0023] In order to reduce the lifting speed of the lifting column 6 and avoid the problem of excessive lifting speed, the first gear 11 and the second gear 12 are both rotatably connected to the inside of the equipment box 1, and the ratio of the number of teeth of the first gear 11 and the second gear 12 is 1:3.

[0024] To facilitate the assembly and disassembly of the device, mounting plates 2 are fixed to both sides of the equipment box 1, and mounting holes are opened on the outer surfaces of the two mounting plates 2. The outer surfaces of the two lifting blocks 15 are respectively attached to the inner walls of the two sliding areas 19.

[0025] To facilitate the filling of oily liquids, one end of each of the two filling ports 7 is connected to the interior of the two sliding areas 19, and a piston 8 is movably plugged inside each of the two filling ports 7.

[0026] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0028] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
