Description

Technical Field

[0001] This utility model belongs to the field of battery swapping technology for new energy vehicles, and relates to a power frame for battery swapping. Background Technology

[0002] With the rapid development of new energy technologies, electrification has become an important development direction in the transportation sector. Compared with traditional fuel vehicles, electric vehicles have shown significant advantages in energy conservation and emission reduction, lower operating costs, and improved energy efficiency. However, the widespread adoption of electric vehicles still faces key challenges such as limited driving range and long charging times, especially in the heavy commercial vehicle sector, such as large trucks, where the demand for high energy density and rapid refueling is even more urgent.

[0003] Currently, the main energy replenishment methods for large electric trucks include conventional charging and battery swapping. Conventional charging is limited by battery charging speed; even with high-power fast charging technology, a complete energy replenishment still takes a considerable amount of time, making it difficult to meet the demands of high-intensity, continuous operation scenarios such as long-haul logistics. In contrast, battery swapping, by quickly removing depleted batteries and replacing them with fully charged ones, can achieve highly efficient energy replenishment within minutes, significantly improving vehicle uptime and operational efficiency. Therefore, it is considered an effective way to solve the energy replenishment bottleneck of electric heavy-duty trucks.

[0004] In typical battery swapping systems, the battery packs of large trucks are usually installed in the upper part of the vehicle chassis. This layout helps to lower the vehicle's center of gravity, optimize space utilization, and facilitate centralized battery management. However, this design also places specific technical requirements on battery swapping operations: the removal and installation of batteries must be carried out from above the vehicle, meaning that the old battery needs to be lifted vertically or at an angle from above the vehicle body, and the new battery needs to be precisely installed into the battery compartment along the same path.

[0005] To automate and improve the efficiency of the battery swapping operation, various battery swapping devices and handling mechanisms have emerged in the existing technology. However, most traditional battery swapping equipment uses steel cable traction for vertical lifting or horizontal transport of batteries, resulting in long battery swapping cycles and problems with swaying and poor stability during battery transport. Utility Model Content

[0006] The purpose of this invention is to provide a power frame for battery swapping, which has the ability to move quickly and smoothly, and can realize the efficient transfer of batteries between the vehicle and the charging area, thereby improving the overall battery swapping efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides a power frame for battery swapping, including two opposing longitudinal slide rails, and two opposing and perpendicular transverse slide rails at one end of the two longitudinal slide rails. A longitudinal displacement frame is slidably connected to the two longitudinal slide rails. Both sides of the longitudinal displacement frame are rotatably connected to longitudinal drive rollers that are respectively rolled and connected to the corresponding longitudinal slide rails. A longitudinal drive motor for driving the longitudinal drive rollers to rotate is installed inside the longitudinal displacement frame. A power battery swapping frame is connected below the longitudinal displacement frame. At least two electric telescopic cylinders are rotatably connected between the longitudinal displacement frame and the power battery swapping frame. Each electric telescopic cylinder is tilted left and right and connected between the longitudinal displacement frame and the power battery swapping frame. All the electric telescopic cylinders are staggered left and right.

[0008] Two transverse slide rails are slidably connected to a transverse displacement frame. Both sides of the transverse displacement frame are rotatably connected to transverse drive rollers that are respectively rolled and connected to the corresponding transverse slide rails. A transverse drive motor for driving the transverse drive rollers to rotate is installed inside the transverse displacement frame. The transverse displacement frame is provided with two movable slide rails that correspond one-to-one with the two longitudinal slide rails. Each longitudinal drive roller can move onto the corresponding movable slide rail.

[0009] By adopting the above technical solution, when the power swapping rack needs to be moved, the longitudinal drive motor is first started to drive the longitudinal drive rollers to roll along the longitudinal slide rail, so that the longitudinal displacement rack slides to the appropriate position along the longitudinal slide rail. Then, the electric telescopic cylinder is activated, and by extending the electric telescopic cylinder, the power swapping rack is lowered to the required height for battery removal from the truck. After the battery is removed, the electric telescopic cylinder retracts, and the power swapping rack lifts the battery and slides it along the longitudinal slide rail.

[0010] When the longitudinal displacement frame moves from the longitudinal slide rail to the moving slide rail of the transverse displacement frame, the transverse drive motor is started to drive the transverse drive roller to roll along the transverse slide rail, so that the transverse displacement frame slides along the transverse slide rail to the appropriate position and the battery is put down to charge.

[0011] Then, move the battery to the fully charged battery using the lateral displacement frame, remove the battery, move it in the opposite direction to the truck position, and install the battery onto the truck using the mechanism on the power swapping rack.

[0012] The present invention is further configured such that each transverse slide rail is located above the longitudinal slide rail, so that the longitudinal displacement frame can pass under the transverse slide rail.

[0013] The present invention is further configured such that each movable slide rail is connected upward to the transverse displacement frame via a vertical connecting strip.

[0014] The present invention is further configured such that a longitudinal mounting frame is provided above the longitudinal slide rail along its length direction, and each longitudinal slide rail is connected upward to the longitudinal mounting frame through multiple first connecting strips.

[0015] The present invention is further configured such that a horizontal mounting bracket is provided above the horizontal slide rail along its length, and each horizontal slide rail is connected upward to the horizontal mounting bracket through multiple second connecting strips.

[0016] The present invention is further configured such that each side of the longitudinal displacement frame is rotatably connected to a longitudinal support roller that is respectively rolledly connected to the corresponding longitudinal slide rail, and the two longitudinal drive rollers and the two longitudinal support rollers are distributed at the four corners of the longitudinal displacement frame.

[0017] The present invention is further configured such that each side of the transverse displacement frame is rotatably connected to a transverse support roller that is respectively rolledly connected to the corresponding transverse slide rail, and the two transverse drive rollers and the two transverse support rollers are distributed at the four corners of the transverse displacement frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Firstly, by adopting a design of longitudinal and transverse slide rails, combined with longitudinal and transverse drive rollers, the power swapping rack can move quickly and smoothly on a two-dimensional plane, greatly improving the efficiency of the swapping operation.

[0021] Secondly, the tilting connection design of the electric telescopic cylinder not only enhances the stability of the power swapping rack, but also ensures that the battery remains horizontal during disassembly and installation, preventing battery shaking and improving the safety of the swapping operation.

[0022] Thirdly, by setting each transverse slide rail above the longitudinal slide rail and designing a movable slide rail that allows the longitudinal displacement frame to pass under the transverse slide rail, this ingenious spatial layout greatly saves floor space, making the battery swapping system more compact and efficient.

Detailed Implementation

[0027] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the power frame for battery swapping proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0028] Example, refer to Figure 1-3 A power frame for battery swapping includes two opposing longitudinal slide rails 1. A longitudinal mounting frame 2, extending along the length of each slide rail 1, is positioned above the slide rail 1. Each longitudinal slide rail 1 is connected upwards to the longitudinal mounting frame 2 via multiple first connecting strips 3. A longitudinal displacement frame 4 is slidably connected to the two longitudinal slide rails 1. Each side of the longitudinal displacement frame 4 is rotatably connected to a longitudinal drive roller 5, which is respectively rolled and connected to the corresponding longitudinal slide rail 1. Two longitudinal drive motors 6 are installed inside the longitudinal displacement frame 4 to drive the longitudinal drive rollers 5. Each side of the longitudinal displacement frame 4 is rotatably connected to a longitudinal support roller 7, which is respectively rolled and connected to the corresponding longitudinal slide rail 1. The two longitudinal drive rollers 5 and the two longitudinal support rollers 7 are distributed at the four corners of the longitudinal displacement frame 4. Driven by the longitudinal drive motors 6, the longitudinal displacement frame 4 can slide along the longitudinal slide rails 1.

[0029] A power swapping frame 8 is connected below the longitudinal displacement frame 4. The power swapping frame 8 integrates a mechanism for assembling and disassembling the car motor. Three electric telescopic cylinders 9 are rotatably connected between the longitudinal displacement frame 4 and the power swapping frame 8. Each electric telescopic cylinder 9 is connected to the longitudinal displacement frame 4 and the power swapping frame 8 at a left-right tilt. The three electric telescopic cylinders 9 are staggered left-right, or two electric telescopic cylinders 9 can be staggered left-right, so that when the electric telescopic cylinders 9 extend and retract simultaneously, they can drive the power swapping frame 8 to rise or fall.

[0030] Two opposing and perpendicular transverse slide rails 10 are provided at one end of the two longitudinal slide rails 1. A transverse mounting bracket 11 is provided above the transverse slide rail 10 along its length. Each transverse slide rail 10 is connected to the transverse mounting bracket 11 upward through multiple second connecting strips 12. Each transverse slide rail 10 is located above the longitudinal slide rail 1, so that the longitudinal displacement bracket 4 can pass under the transverse slide rail 10. A transverse displacement bracket 13 is slidably connected to the two transverse slide rails 10.

[0031] Two transverse drive rollers 14 are rotatably connected to both sides of the transverse displacement frame 13 and are respectively rolledly connected to the corresponding transverse slide rails 10. Two transverse drive motors 15 are installed inside the transverse displacement frame 13 to drive the transverse drive rollers 14 to rotate. Two transverse support rollers 16 are rotatably connected to both sides of the transverse displacement frame 13 and are respectively rolledly connected to the corresponding transverse slide rails 10. The two transverse drive rollers 14 and the two transverse support rollers 16 are distributed at the four corners of the transverse displacement frame 13. Two movable slide rails 17 are provided downward on the transverse displacement frame 13, which correspond one-to-one with the two longitudinal slide rails 1. Each movable slide rail 17 is connected upward to the transverse displacement frame 13 through a vertical connecting strip 18. Each longitudinal drive roller 5 can move onto the corresponding movable slide rail 17.

[0032] Working principle: When the power swapping rack 8 needs to be moved, the longitudinal drive motor 6 is first started to drive the longitudinal drive roller 5 to roll along the longitudinal slide rail 1, so that the longitudinal displacement frame 4 slides along the longitudinal slide rail 1 to the appropriate position. Then, the electric telescopic cylinder 9 is started, and by extending the electric telescopic cylinder 9, the power swapping rack 8 is lowered to the required height to remove the battery from the truck. After the battery is removed, the electric telescopic cylinder 9 is shortened, and the power swapping rack 8 lifts the battery and slides it along the longitudinal slide rail 1.

[0033] When the longitudinal displacement frame 4 moves from the longitudinal slide rail 1 to the moving slide rail 17 of the transverse displacement frame 13, the transverse drive motor 15 is started to drive the transverse drive roller 14 to roll along the transverse slide rail 10, so that the transverse displacement frame 13 slides along the transverse slide rail 10 to the appropriate position and the battery is put down to charge.

[0034] Then, the battery is moved to the fully charged battery by the lateral displacement frame 13, the battery is removed and moved in the opposite direction to the truck position, and the battery is installed on the truck by the mechanism on the power swapping frame 8.

[0035] Furthermore, by setting longitudinal support rollers 7 and lateral support rollers 16, the stability of the longitudinal displacement frame 4 and lateral displacement frame 13 during the sliding process can be further improved, reducing swaying and thus improving the accuracy and safety of the battery swapping operation. At the same time, the staggered left-right distribution design of the electric telescopic cylinder 9 also makes the power battery swapping frame 8 more stable during the lifting and lowering process, further improving the battery swapping efficiency.

[0036] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
