Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an automotive engine compartment crossbeam structure. Background Technology

[0002] With the rapid development of the automotive industry, automobiles have become an indispensable means of transportation for people. The number of cars on the road is increasing year by year, and more and more people own private cars. The front engine compartment of a car contains a large number of components, and how to improve the compactness of the component layout in the front engine compartment has always been a problem that needs to be considered in automotive development and design.

[0003] A search revealed that utility model patent CN222408395U discloses a crossbeam for the front engine compartment of an automobile. The crossbeam has a liquid storage chamber, and a coolant filling port and a coolant outlet are provided on the crossbeam, which are connected to the liquid storage chamber. The coolant filling port is covered with a cap. This crossbeam integrates the function of a coolant reservoir, realizing the sharing of the crossbeam and the coolant reservoir. This can effectively reduce the number of parts in the front engine compartment, thereby saving space in the front engine compartment and also effectively saving costs.

[0004] However, the aforementioned patent has the following shortcomings: although multiple reinforcing plates can support the interior of the crossbeam to enhance its strength, the lack of reinforcement along the length of the crossbeam affects its overall strength; furthermore, other automotive components are installed above the crossbeam, and the presence of coolant filler necks and caps hinders their installation, resulting in poor practicality. Therefore, we propose a new automotive engine compartment crossbeam structure. Utility Model Content

The top surface of the partition 16 is provided with an upper liquid permeation channel 17, and the bottom of the partition 16 is provided with a lower liquid permeation channel 18.

[0028] In this embodiment, the partition 16 can be welded to the rectangular crossbeam 1 or be an integrally formed structure. By designing multiple partitions 16, the structural strength of the rectangular crossbeam 1 can be improved, and the reinforcing effect of the rectangular crossbeam 1 on the overall vehicle structural strength can be enhanced. At the same time, the multiple partitions 16 set in the rectangular crossbeam 1 can divide the liquid storage tank 3 into multiple partition chambers to prevent the coolant from shaking violently in the liquid storage tank 3.

[0029] For details, please refer to Figure 1 and Figure 2 The top of the rectangular beam 1 is provided with a coolant filling port 4, and a cap 5 is threaded onto the outside of the coolant filling port 4.

[0032] In this embodiment, the crossbeam is installed between the front wheel arches on both sides of the front compartment through the cooperation of the mounting hole 14, the mounting tube 15 and the bolts, which enhances the stability of the front compartment and improves the torsional stiffness.

[0033] For details, please refer to Figure 3 A return port 12 is fixedly sleeved on the top of the rectangular beam 1, and a vent pipe 13 is fixedly sleeved on the top of the rectangular beam 1.

[0034] In this embodiment, the coolant is returned to the inner cavity of the storage tank 3 through the cooperation of the return port 12 and the pipeline. The vent pipe 13 can be connected to the thermal management system through the external pipeline, which is conducive to venting the gas or water vapor in the system into the storage tank 3, thereby balancing the system pressure.

[0035] For details, please refer to Figures 1 to 4 The rectangular beam 1, side reinforcing ribs 6, bottom reinforcing ribs 7, sealing plate 2, partition plate 16, upper support frame 9, and support base 10 are all made of aluminum alloy.

[0036] In this embodiment, the aluminum alloy beam is advantageous for lightweight design, has a simple structure, good corrosion resistance, and low cost.

[0037] Working principle: In use, firstly, multiple side reinforcing ribs 6 are welded to the side of the rectangular crossbeam 1, multiple bottom reinforcing ribs 7 are welded to the bottom of the rectangular crossbeam 1, and multiple baffles 16 are welded to the inner cavity of the liquid storage tank 3 inside the rectangular crossbeam 1 to ensure the overall strength of the crossbeam. Then, the crossbeam is installed between the front wheel arches on both sides of the front compartment through the mounting holes 14, mounting pipes 15 and bolts, and the reservoir cap 5 is removed. Coolant is injected into the inner cavity of the liquid storage tank 3 through the coolant filler port 4. The coolant in the inner cavity of the liquid storage tank 3 is discharged through the coolant outlet 8 and pipe to cool the vehicle equipment. The coolant is returned to the inner cavity of the liquid storage tank 3 through the pipe and return port 12. Finally, the equipment to be installed on the crossbeam is placed on the support base 10, and the equipment is fixed on the crossbeam through the bolts and screw holes 11.
