Description

Technical Field

[0001] This utility model relates to a high-strength battery protection beam. Background Technology

[0002] As a core component of new energy vehicles and power storage systems, the safety and reliability of batteries directly affect the overall vehicle performance and lifespan. During vehicle operation or equipment operation, battery packs are primarily vulnerable to protruding foreign objects on the ground. Therefore, an independent protective beam needs to be installed at the front of the battery pack to further protect the front of the battery and prevent foreign objects from scratching the protective beam by preemptively colliding with it.

[0003] The existing protective beams of this type are single-layer structures, which have insufficient impact resistance.

[0004] Based on the above problems, we designed a high-strength battery protection beam with stronger impact resistance and better protection against bottoming out. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-strength battery protection beam with stronger impact resistance and better protection against bottoming out.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A high-strength battery protection beam includes two connectors, and a primary beam and a secondary beam installed between the two connectors. The primary beam protects the front of the secondary beam, and the lower end face of the secondary beam is lower than the lower end face of the primary beam. The lower end face of the primary beam is flush with the lower end face of the battery pack, and the secondary beam maintains a gap of more than 3 cm with the battery pack.

[0008] Preferably, a connecting bolt is provided at the front of the connector, the primary beam is fixed to the front of the connector by the connecting bolt, a right-angle groove is machined at the bottom of the inner side of the connector, a first connecting bolt is vertically provided at the bottom of the right-angle groove, the secondary beam is fixed by the first connecting bolt, and the right-angle groove limits the upward movement of the secondary beam.

[0009] Preferably, an elastic rubber buffer pad is fitted between the primary beam and the connector, and the connecting bolt passes through the buffer pad.

[0010] Preferably, a guide surface is machined at the bottom front of the primary beam.

[0011] Preferably, the guiding surface is an arc-shaped surface or an inclined surface.

[0012] Preferably, a gap of 1 to 2 cm is formed between the primary beam and the secondary beam.

[0013] Preferably, the secondary beam is an inverted trapezoid, and a reinforcing beam is provided on the inner side of the secondary beam.

[0014] Preferably, the reinforcing beam and the secondary beam are cast as a single unit, and a slot is formed between the reinforcing beam and the secondary beam. A rubber buffer block is embedded in the slot, and the rear end face of the buffer block acts on the battery pack.

[0015] The beneficial effects of this utility model are:

[0016] This device employs a primary beam and a secondary beam. The primary beam protects the front of the secondary beam, providing dual impact resistance.

[0017] The primary beam is installed on the front of the two connectors, thus providing stronger resistance to frontal impacts. The secondary beam is installed in a right-angle slot, and its upward movement is restricted by the right-angle slot, as is its backward movement. Therefore, the secondary beam not only provides resistance to frontal impacts but also prevents bottoming out, effectively protecting the battery pack.

[0018] This device has a simple structure, is easy to install, and is suitable for widespread use. Attached Figure Description

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] See Figure 1 The high-strength battery protection beam shown includes two connectors 1, and a primary beam 2 and a secondary beam 3 installed between the two connectors 1. The primary beam 2 protects the front of the secondary beam 3, and the lower end face of the secondary beam 3 is lower than the lower end face of the primary beam 2. The lower end face of the primary beam 2 is flush with the lower end face of the battery pack, and the secondary beam 3 maintains a gap of more than 3 cm with the battery pack.

[0032] In the above technical solution, the primary beam is made of high-strength steel, and the secondary beam is made of aluminum alloy.

[0033] In terms of thickness, the thickness of the first-level beam is 1cm, and the thickness of the second-level beam is 1.4cm.

[0034] When a foreign object passes under a vehicle while it is moving at high speed, the primary beam absorbs the main impact. When the primary beam deforms to the point of contact with the secondary beam, the secondary beam provides further collision protection.

[0035] In the above technical solution, the lower end faces of the primary beam 2 and the secondary beam 3 are misaligned. The lower end face of the secondary beam 3 is slightly higher than the lower surface of the battery pack. Its function is to further intercept foreign objects on the ground and reduce damage to the battery pack.

[0036] Connector 1 is fixed to the longitudinal beam of the vehicle by bolts, and welding is added at the contact point.

[0037] See Figure 2 and Figure 3 As shown, a connecting bolt 11 is provided at the front of the connector 1. The primary beam 2 is fixed to the front of the connector 1 by the connecting bolt 11. A right-angle groove 12 is machined at the bottom of the inner side of the connector 1. A first connecting bolt 13 is vertically provided at the bottom of the right-angle groove 12. The secondary beam 3 is fixed by the first connecting bolt 13. The right-angle groove 12 limits the upward movement of the secondary beam 3.

[0038] In the above technical solution, the primary beam 2 is located at the front of the connector 1, which can better prevent frontal impact.

[0039] The secondary beam 3 is installed in the right-angle groove 12, which can better withstand upward forces and also withstand positive impact forces.

[0040] See Figure 2 As shown, an elastic rubber buffer pad 21 is installed between the primary beam 2 and the connector 1, and the connecting bolt 11 passes through the buffer pad 21.

[0041] The cushioning pad 21 can provide cushioning and protection.

[0042] See Figure 4 and Figure 5 As shown, a guide surface 22 is machined at the bottom front of the primary beam 2.

[0043] See Figure 4 As shown, the guide surface 22 is an arc-shaped surface.

[0044] See Figure 5 As shown, the guide surface 22 is an inclined surface.

[0045] In the above technical solution, the guide surface 22 is designed to better manage the airflow under the car.

[0046] See Figure 2 As shown, a gap of 2cm is formed between the primary beam 2 and the secondary beam 3.

[0047] By using certain intervals, the deformation space of the first-stage beam 2 is increased.

[0048] See Figure 6 As shown, the secondary beam 3 is an inverted trapezoid, and a reinforcing beam 31 is provided on the inner side of the secondary beam 3.

[0049] The secondary beam 3 of this structure can better withstand upward impact forces, mainly when the car bottoms out.

[0050] See Figure 6 As shown, the reinforcing beam 31 and the secondary beam 3 are cast integral structures, and a cavity 32 is formed between the reinforcing beam 31 and the secondary beam 3. A rubber buffer block 33 is embedded in the cavity 32, and the rear end face of the buffer block 33 acts on the battery pack.

[0051] The setting of buffer block 33 can further enhance the buffering effect.
