Description

Technical Field

[0001] This utility model relates to the field of battery frame technology, and in particular to a fast battery swapping frame for new energy light trucks. Background Technology

[0002] Currently, new energy vehicle technology is developing rapidly both domestically and internationally, but it also faces many challenges. There are currently two ways to supply electricity: charging and battery swapping. However, charging can easily damage battery life and requires excessively long waiting times, while battery swapping can effectively avoid these problems. The fast battery swapping framework serves as a key supporting structure for achieving automatic battery replacement.

[0003] During long-term and frequent battery swapping, the weight of the battery pack is concentrated on the frame, which can easily cause the frame to bend, deform, or even collapse in some areas, affecting the structural stability and service life. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] The fast battery swapping framework for new energy light trucks includes:

[0006] Frame;

[0007] A support beam is fixedly installed in the middle of the frame and is arranged along the width of the frame. The support beam divides the cavity of the frame into two spaces for accommodating light truck battery packs.

[0008] Two sets of crossbars are installed on the frame and located at the top of the support beam, and are arranged along the extension direction of the frame;

[0009] Two sets of connecting rods are integrally formed and set between the two sets of crossbars, and are respectively located on both sides of the support beam.

[0010] As an improvement to the above technical solution, a support frame is provided at the connection between the crossbar and the support beam, and support plates are integrally formed on both sides of the top of the support frame, with the bottom of the support plates abutting against the top of the support beam.

[0011] As an improvement to the above technical solution, the support beam has a U-shaped cross-section, and multiple sets of reinforcing plates are arranged at intervals inside the support beam along its extension direction, with an arc-shaped groove on the top of each set of reinforcing plates.

[0012] As an improvement to the above technical solution, at least two sets of connecting plates for installing connecting wires are fixedly connected between one set of the crossbars and the frame.

[0013] As an improvement to the above technical solution, a connector for installing connecting wires is fixedly provided on the crossbar and between the two sets of connecting pieces.

[0014] The beneficial effects of this utility model are:

[0015] The frame structure, in conjunction with the support beams, provides lateral support and spatial separation, effectively distributing the weight of the battery pack and preventing the frame from collapsing in the middle. The crossbars, support beams, and frame structure form a multi-point support system, enhancing bending resistance. The symmetrical, integrated layout of the connecting rods significantly improves the frame's torsional resistance, avoiding torsional deformation caused by uneven stress, and significantly improving the overall reliability and fatigue life of the frame structure.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The fast battery swapping framework for new energy light trucks includes:

[0022] Frame 10;

[0023] The support beam 20 is fixedly installed at the middle position of the frame 10 and is arranged along the width direction of the frame 10. The support beam 20 divides the cavity of the frame 10 into two sets of spaces for accommodating light truck battery packs.

[0024] Two sets of crossbars 11 are installed on the frame 10 and located on top of the support beam 20, and are arranged along the extension direction of the frame 10;

[0025] Two sets of connecting rods 50 are integrally formed and set between the two sets of crossbars 11, and are respectively located on both sides of the support beam 20.

[0026] Specifically, the frame 10 is the basic structure of the entire battery swapping frame. It is formed by connecting and enclosing the frame with crossbeams and longitudinal beams in sequence. The frame 10 has an open bottom design, providing a channel for the light truck battery pack to move from bottom to top, facilitating the entry of the light truck battery pack into the frame 10. When the battery pack is lifted into the frame 10, the support beam 20 increases the lateral support force, preventing the frame 10 from collapsing or bending due to the concentrated weight of the battery. It also serves as the installation reference point for the crossbar 11 and connecting rod 50, enhancing the overall structural rigidity. The crossbar 11 shares part of the lateral load and, together with the support beam 20 and the frame 10, forms a multi-point support system, improving the overall bending resistance of the frame and preventing structural deformation due to lateral forces. The connecting rod 50 forms a symmetrical layout, enhancing the overall rigidity of the frame, improving torsional performance, and avoiding structural twisting or tilting due to uneven force on one side. The one-piece molding process reduces weak points in welding, improving fatigue life and structural reliability. Together with the crossbars and support beams, it forms a "stabilizing unit," enhancing the overall structural stability.

[0027] In one embodiment, a support frame 111 is provided at the connection between the crossbar 11 and the support beam 20. Support plates 112 are integrally formed on both sides of the top of the support frame 111. The bottom of the support plates 112 abuts against the top of the support beam 20. The support frame 111 increases the contact area between the crossbar 11 and the support beam 20, improving the structural strength and rigidity of the connection between the crossbar 11 and the support beam 20. Serving as the installation base for the crossbar 11, it enhances the stability of the connection between the crossbar 11 and the support beam 20 and acts as a local reinforcing rib, preventing stress concentration from causing… If the connection part deforms or cracks, the support plate 112 directly transfers part of the load borne by the crossbar 11 to the support beam 20, disperses the pressure, avoids stress concentration, provides a limiting function, prevents the crossbar 11 from shifting laterally during the battery swapping process, enhances the shear resistance of the connection part, and improves the overall stability of the structure. With the addition of the support frame 111 and the support plate 112, the battery swapping frame achieves structural reinforcement at the key connection parts between the crossbar and the support beam. Together with other components, it forms a more complete force transmission and stability system, ensuring the reliability and safety of the battery swapping frame under high-frequency use.

[0028] The support beam 20 has a U-shaped cross-section. Multiple sets of reinforcing plates are spaced apart inside the support beam 20 along its extension direction. Each set of reinforcing plates has an arc-shaped groove at its top. The U-shaped support beam 20 can provide a larger bending moment of inertia and enhance the lateral bearing capacity. The reinforcing plates enhance the longitudinal stiffness of the support beam, which can effectively limit the local deformation of the support beam 20. At the same time, it can also improve the torsional performance of the support beam, prevent torsion caused by lateral forces, and ensure that the support beam maintains structural integrity under complex stress conditions. The arc-shaped groove serves as a stress relief structure, reducing the risk of cracks in the reinforcing plates or support beam 20 due to stress concentration.

[0029] In one embodiment, at least two sets of connecting plates 30 for installing connecting wires are fixedly connected between one set of the crossbars 11 and the frame 10. The connecting plates 30 serve as a wiring support structure for the power cord and as an extension of the connection structure between the crossbars 11 and the frame 10. While fixing the connecting wires, they can help disperse the influence of the cable's own weight and external forces on the frame, and enhance the overall rigidity of the connection between the crossbars 11 and the frame 10.

[0030] In one embodiment, a connector 40 for installing a connecting line is fixedly provided on the crossbar 11 and located between the two sets of connecting pieces 30. When the robotic arm pulls the connecting line or the vehicle vibrates, the connector 40 transmits the external force to the crossbar 11 through a rigid connection. Then, through the synergistic action of the crossbar 11, the support beam 20, and the frame 10, the load is distributed to the entire frame, further enhancing the crossbar's resistance to deformation.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
