Description

Technical Field

[0001] The utility model relates to the field of automobile structures, in particular to an automobile battery arrangement structure. Background Art

[0002] With the increase in new energy vehicles, dangerous accidents caused by battery collisions occur frequently. Among them, increasing the ground clearance of car batteries is a very effective measure to avoid collisions.

[0003] However, in the commercial vehicle sector, due to the need to carry and haul cargo, non-load-bearing structures with beams are generally used. The batteries of new energy vehicle models using single-pack batteries are generally arranged under the frame, leaving only an installation gap between the upper part of the vehicle battery and the lower wing surface of the frame longitudinal beam. Since the belly height of the frame longitudinal beam is generally ≥140mm and due to the need to haul cargo, when the vehicle is fully loaded, the height of the vehicle battery from the ground is generally low, increasing the risk of battery collision. Utility Model Content

[0006] The beneficial effects of this solution are: the ground clearance of the car battery is a very effective measure to avoid bumps. This solution reserves installation space between the two longitudinal beams so that the car battery overlaps with the frame, and the upper surface of the car battery is aligned with the upper wing surface of the longitudinal beam, thereby raising the ground clearance of the car battery. The car battery can generally be raised by the belly height of one frame longitudinal beam, thereby increasing the ground clearance of the car battery when the commercial vehicle is fully loaded, thereby reducing the risk of battery bumps.

[0010] Beneficial effect: By distinguishing the connection positions of the first connection part and the second connection part, the probability of incorrect assembly is reduced and the assembly efficiency is improved.

[0011] Furthermore, a sliding groove is provided on the first connecting portion, and the connecting member can slide on the shell through the sliding groove.

[0012] Furthermore, a positioning pin is fixed on the longitudinal beam, and a positioning groove adapted to the positioning pin is provided on the second connecting portion.

[0013] Beneficial effect: Through the setting of the slide groove, positioning pin and positioning groove, when an error occurs in the installation of the positioning pin, the connecting piece can be slid a certain distance through the slide groove so that the positioning groove and the positioning pin are adapted, thereby improving the installation fault tolerance rate.

[0014] Furthermore, a reinforcing rib is provided between the first connecting portion and the second connecting portion.

[0015] Beneficial effect: By setting the reinforcing ribs, the structural strength of the connector is effectively improved, and the structural stability of the connector is improved.

[0016] Furthermore, the first connecting portion and the second connecting portion are of split design.

[0017] Furthermore, the first connecting portion includes a first mounting surface and a second mounting surface, both of which are provided with several groups of mounting holes. The first mounting surface is fixedly connected to the bottom of the longitudinal beam through the mounting holes, and the second connecting portion can be fixedly connected to the second mounting surface through any group of mounting holes.

[0018] Furthermore, a reinforcing rib is fixed between the first mounting surface and the second mounting surface.

[0019] Based on the above technical features, the beneficial effect of this solution is: through the setting of the split first connecting part and the second connecting part, when the design height of the car battery is too high, the second mounting part can be moved downward a certain distance, and the appropriate mounting hole can be selected to fix the second connecting part, thereby being suitable for the installation of different models of car batteries and improving the versatility of the connector.
