本发明提供了一种发动机舱侧边梁结构，其包括发动机舱侧边梁内板、发动机舱侧边梁外板、A柱加强板、A柱上框加强板、A柱内板、发动机舱盖板铰链安装板以及侧围外板，发动机舱侧边梁外板与发动机舱侧边梁内板相对焊接后围成一空腔；发动机舱盖板铰链安装板设置在发动机舱侧边梁内板上；发动机舱侧边梁外板的连接端与A柱上框加强板和A柱加强板焊接连接；发动机舱侧边梁内板的安装端与A柱上框加强板和A柱加强板焊接连接；A柱内板与A柱加强板和A柱上框加强板的一侧焊接连接，侧围外板与A柱加强板和A柱上框加强板的另一侧焊接连接。本发明的发动机舱侧边梁结构，能够较好地避免侧围外板因受力过大而易于开裂的问题。

The invention provides a side beam structure of an engine compartment, which includes an engine compartment side beam inner panel, an engine compartment side beam outer panel, an A-pillar reinforcement panel, an A-pillar upper frame reinforcement panel, an A-pillar inner panel, and an engine compartment The cover hinge mounting plate and the side wall outer panel, the engine compartment side beam outer panel and the engine compartment side beam inner panel are welded to form a cavity; the engine compartment cover hinge mounting plate is arranged on the engine compartment side beam inner panel Upper; the connecting end of the side beam outer plate of the engine compartment is welded to the A-pillar upper frame reinforcement plate and the A-pillar reinforcement plate; the installation end of the engine compartment side beam inner plate is welded to the A-pillar upper frame reinforcement plate and the A-pillar reinforcement plate Connection: The A-pillar inner plate is welded and connected to one side of the A-pillar reinforcement plate and the A-pillar upper frame reinforcement plate, and the side wall outer plate is welded and connected to the A-pillar reinforcement plate and the other side of the A-pillar upper frame reinforcement plate. The side beam structure of the engine compartment of the present invention can better avoid the problem that the side wall outer panel is prone to cracking due to excessive force.
