Description

Technical Field

[0001] The utility model relates to the technical field of top side beams of passenger cars, in particular to a top side beam component of a passenger car. Background Art

[0002] The roof side beams of buses refer to the structural support parts of the vehicle roof, usually made of metal. They are located at the edge of the vehicle roof and connect the roof to the body, giving the body a higher structural strength, thereby improving the safety of the passengers in the vehicle. In addition, the roof side beams of buses not only provide important support as part of the body structure, but also play an important role in aesthetics. Their design is exquisite and practical and can be used as decorative elements to enhance the overall appearance and fashion sense of the car.

[0003] A Chinese patent discloses an arc-shaped passenger bus top side beam component (authorization announcement number CN208102117U). This patented technology uses low-density, high-strength aluminum alloy materials for the top side beams, effectively reducing the weight of the component and improving the endurance of the bus. The upper and lower slots are convenient for fixing the top arch beam and side columns to it through connecting angles, bolts and inserts, eliminating the welding process and reducing the skill requirements for workers.

[0004] However, the existing top side beams are mostly made of aluminum alloy to reduce the weight of the components, resulting in poor strength. For example, the above-mentioned reference document uses aluminum alloy. In actual application, due to its poor internal space strength, it is easy to deform in the event of a collision, resulting in low safety. Therefore, those skilled in the art provide a bus top side beam assembly to solve the problems raised in the above background technology. Utility Model Content

[0010] As a further solution of the present invention: the first sound insulation layer and the second sound insulation layer have the same thickness, and the first sound insulation layer and the second sound insulation layer are filled with sound insulation foam.

[0011] As a further solution of the utility model: the first reinforcing rod is arranged in a cylindrical shape inside the upper top side beam and the lower top side beam.

[0012] As a further solution of the utility model: a second reinforcement rod is arranged through the outside of the first reinforcement rod, and two ends of the second reinforcement rod are fixed to the inner side of the upper top side beam.
