Description

Technical Field

[0001] The invention relates to an improvement of a battery structure of a battery swap station. Background Art

[0002] In recent years, with the development of new energy, electric vehicles have become popular. However, electric vehicles have insufficient range, and the way to supplement energy by charging is relatively slow, which is very unfriendly to new energy operating vehicles, and the number of public charging piles cannot meet the needs of the majority of electric vehicle users. The way to supplement energy by battery swapping can solve the above contradictions. There are more and more types of battery swapping stations on the market. The battery swapping efficiency of battery swapping stations is its biggest selling point, so battery swapping stations cannot do without a stable, reliable and simple battery transfer system.

[0003] The forks used in conventional battery transport systems need to have good rigidity because of the large mass of the batteries, which results in the entire fork being very large and heavy. When transporting batteries, the fork needs to be extended for a long time, which causes the fork to bend and deform, making the battery replacement process risky. In addition, due to the large size of the fork, the minimum height of the transport system is limited and cannot be made very low. The other storage systems that work with it are also limited in minimum height, resulting in space waste and reduced efficiency. Summary of the invention

[0004] In order to overcome the shortcomings of the existing fork-type battery transfer system, such as the transfer fork being easily deformed and being bulky, the present invention provides a fork-type battery transfer system with a fast transfer speed.

[0005] The technical solution of the present invention to solve its technical problem is: a fork-type battery transfer system, including a transfer frame, a roller group is provided at the bottom of the transfer frame; a transverse guide rail is provided on the transfer frame, a slide is slidably provided on the transverse guide rail, a servo motor is provided above the transverse guide rail, an output gear is provided on the output end of the servo motor, and the output gear is engaged with the rack on the slide; a fork is provided at each end of the slide, and a battery buckle and a driving device for driving the battery buckle to buckle are provided on the fork.

[0006] The fork is further developed. The fork includes a fork plate, a rotating rod is hinged in the middle of the fork plate, the driving device is a rotating rod motor installed on the rear side of the rotating rod, and a connecting rod is hinged at each end of the rotating rod; a battery buckle is rotatably provided at each end of the fork plate, a rocking rod is provided on the battery buckle, and the head of the rocking rod is hinged on the outer end of the connecting rod, so that the connecting rod rotates to drive the battery buckle to extend out of the fork plate.

[0007] The battery buckle is structurally designed, and the battery buckle is strip-shaped and extends out from the lower side of the fork plate.

[0008] To further improve the structural strength, a reinforcing guard ring is provided at the location where the fork plate is rotatably connected to the battery buckle.

[0009] To facilitate rolling, the rollers of the roller group are composed of a plurality of rollers arranged in a row, and the two ends are connected to two straight rods.

[0010] The design of the rollers includes two groups of rollers, which are located on the left and right sides of the transfer frame respectively.

[0011] In order to reduce the weight, the fork plate is provided with hollow holes to reduce the weight.

[0012] The transverse guide rail on the fork plate is located in the middle of the transfer frame.

[0013] To facilitate installation and prevent the fork plate from being damaged, a connecting piece is provided between the fork plate and the transverse guide rail.

[0014] A design of a transfer frame, wherein the transfer frame is provided with at least two layers of frames, the frames are divided into an upper frame and a lower frame, the roller group is located on the lower frame, and the transverse guide rail is located on the upper frame.

[0015] When the present invention is in use and the transfer mechanism collects the batteries waiting at the transfer location, the connecting rod mechanism of the battery bayonet assembly is first located at the origin position, the battery buckle is in a retracted state, the fork is extended into position, and then the connecting rod mechanism moves, and the fork returns to its original position after the battery buckle is lowered into position, and the battery is collected into the transfer frame; after the transfer frame reaches the designated position, the fork extends and sends the battery to the designated position, and after it is in position, the connecting rod returns to its original position, and the battery buckle is retracted and the fork is restored.

[0016] The installation method is that the roller group is installed on the lower frame of the transfer frame, with a total of two rows, and the rollers in each row are installed at equal intervals; the fork is reversely installed on the aluminum profile of the upper frame of the transfer frame; the battery buckle assembly is installed on the mounting plates at both ends of the telescopic fork, and the servo motor drives the connecting rod to drive the battery buckle to be retracted and lowered.

[0017] The beneficial effects of the present invention are: 1. The battery transportation form is changed from the original fork lifting form to the fork shifting form. When the fork is lifted, the weight of the battery is borne on the fork, which requires a high strength for the fork. In the fork shifting form, the weight of the battery is borne by the roller, and the fork only increases the rolling force of the battery, so the fork can be made very light. The fork lifting the battery requires space for up and down movement, while the fork shifting the battery saves up and down space because it is a translational movement, and the fork shifting form just makes use of the space for plugging and unplugging the battery plug, which greatly improves the space utilization of the battery rack. 2. This transfer mechanism is used in the field of battery replacement and transportation to achieve fast and efficient battery transportation, ensure the efficiency and reliability of battery replacement, reduce the risk of battery replacement, and reduce design time and cost after standardization; 3. It can be mass-produced after standardization and is easy to maintain; the structure is simple and has good structural strength. BRIEF DESCRIPTION OF THE DRAWINGS
