Description

Technical Field

[0001] This utility model belongs to the technical field of automotive battery frame sub-beams. Specifically, this utility model relates to a new energy battery frame sub-beam structure. Background Technology

[0002] The main body of the sub-beams of existing new energy battery frames is mostly composed of a single profile and its reinforcing beams or plates.

[0003] A patent application (patent number 201721791033.8) published on October 12, 2018, discloses a connection structure between a power battery pack frame and a vehicle body mounting beam for a new energy vehicle, belonging to the technical field of automotive design and manufacturing. This utility model's connection structure includes a power battery pack frame, a vehicle body mounting beam, a mounting reinforcement plate, a nut box, a nut plate, and bolts. The bolts are sequentially fastened through openings in the power battery pack frame, the vehicle body mounting beam, the mounting reinforcement plate, the nut box, and the threaded holes in the nut plate. The nut plate is housed within the nut box, which restricts its horizontal movement. This utility model's connection structure optimizes the structure of the nuts and bolts from a tolerance matching perspective, effectively preventing the safety risk of standard parts pulling out.

[0004] The profiles have specific standard specifications and models, which cannot meet the special height requirements of the sub-beams. Non-standard sized profiles can also be customized, but this involves minimum order quantity, higher costs, and because they are integrated profile structures, they are usually very heavy to ensure strength.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0023] Please see Figure 1-5 A new energy battery frame sub-beam structure includes a vehicle frame 1, a sub-beam mounted on the vehicle frame 1, and a battery frame 2 mounted on the sub-beam. The sub-beam includes a main board 3 mounted on a connector, a support beam on the main board 3 for supporting the battery frame 2, and reinforcing members on the main board 3 to strengthen the support beam and the main board 3. The sub-beam supporting the battery frame 2 is decomposed into multiple parts, which only need to be welded together to form the sub-beam. Under the premise of meeting performance requirements, it can achieve both weight reduction and improved overall structural strength, and can meet the sub-beam height requirements within a certain range, making it widely applicable. The support frame is distributed on the front and rear sides of the main board 3, working with the main board 3 to support the battery frame 2. The width of the main board 3 can be changed according to the required height to meet the height requirements, reducing the cost of replacement and adjustment. At the same time, by welding multiple reinforcing members between the support frame and the main board 3, the strength of the reinforcing members can be improved by using better processes during production due to their simple structure. Compared with a one-piece beam, it can improve the overall strength while reducing the overall structural weight.

[0024] The support beam is divided into an inner support frame 4 and an outer support frame 5, which are set on both sides of the main board 3. The inner support frame 4 is set on the side of the two main boards 3 that are close to each other. The inner support frame 4 and the outer support frame 5 together with the main board 3 form the main support structure for supporting the battery frame 2. By extending the support contact surface on both sides of the main board 3 for supporting the battery frame 2, the battery frame 2 is placed more stably. Since the outer support frame 5 and the inner support frame 4 are located on both sides of the main board 3, they can be used to balance the main board 3 and prevent the main board 3 from tilting or bending.

[0025] The outer support frame 5 has a U-shaped cross-section and an arc-shaped lower surface. The inner support frame 4 also has an arc-shaped lower surface and a weight-reducing hole in the middle. The U-shaped outer support frame 5 can increase the contact area with the battery frame 2, improve the overall stability, and reduce the shaking of the battery frame 2 during the process. Furthermore, the arc-shaped lower surfaces of both the inner support frame 4 and the outer support frame 5 can improve the vertical shear resistance and prevent vertical breakage. At the same time, since the inner support frame 4 is smaller than the outer support frame 5, the required strength is lower. By opening a weight-reducing hole in the inner support frame 4, the weight is reduced and the cost is saved.

[0026] The upper surfaces of the outer support frame 5 and the inner support frame 4 are flush with the upper surface of the main board 3; this ensures that the contact surface between the battery frame 2 and the sub-beam is flat, avoiding tilting and large gaps, and reducing possible vibrations.

[0027] The main board 3 is a C-shaped board. The main board 3 has a top plate 6 and a bottom plate 7 on both sides. The upper and lower sides of the inner support frame 4 are respectively attached to the top plate 6 and the bottom plate 7. The top of the inner support frame 4 has a groove that matches the top plate 6. The C-shaped board structure can improve the strength of the main board 3. The main board 3, the bottom plate 7 and the top plate 6 are integrated structural components. The upper and lower end surfaces of the inner support frame 4 are attached to the top plate 6 and the bottom plate 7. The inner support frame 4 supports the top plate 6 and the bottom plate 7 to prevent the top plate 6 and the bottom plate 7 from being tilted under pressure. The top of the inner support frame 4 has a groove that matches the top plate 6, so that the top surface of the top plate 6 and the top surface of the inner support frame 4 form a plane, ensuring the stability of the battery frame 2.

[0028] A vertical reinforcing plate 8 is provided between the top plate 6 and the bottom plate 7. The vertical reinforcing plate 8 is attached to the surface of the inner support frame 4 near the center of the main plate 3. The vertical reinforcing plate 8 is used to support the top plate 6 and the bottom plate 7, and can also support the inner support frame 4 and the main plate 3, preventing the connection between the inner support frame 4 and the main plate 3 from breaking.

[0029] The main board 3 has a trapezoidal groove in the middle of one side of the top plate 6. An inclined reinforcing plate 9 is provided between the top plate 6 and the bottom plate 7. The inclined reinforcing plate 9 is set along the two sides of the trapezoidal groove. The trapezoidal groove can effectively reduce the material used in the main board 3 and reduce the cost. At the same time, since the upper middle part of the main board 3 is not used for support, it has a low impact on the overall strength of the main board 3. The inclined reinforcing plates 9 are symmetrically distributed on both sides of the trapezoidal groove, and the two ends of the inclined reinforcing plates 9 are connected to the top plate 6 and the bottom plate 7 respectively. This can also serve to support the top plate 6 and the bottom plate 7. Furthermore, since the inclined reinforcing plates 9 are inclined, they can improve the lateral shear resistance of the main board 3.

[0030] The main board 3 has screw holes, and a U-shaped connecting plate 10 is provided between the frame 1 and the main board 3 through screws; it is used to fix the sub-beam to the frame 1.

[0031] The technical advantages of this invention are as follows: the sub-beam used to support the battery frame 2 is decomposed into multiple parts, which can be welded together to form the sub-beam. Under the premise of meeting the performance requirements, it can achieve both weight reduction and improve the strength of the overall structure. It can also meet the sub-beam height requirements within a certain range as much as possible, and has wide applicability.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
