Description

Technical Field

[0001] The utility model relates to the technical field of automobile bodies, in particular to a front water spray frame connection structure for washing a vehicle. Background Art

[0002] When the front water spray rack of a high-pressure cleaning vehicle on the market is connected to the vehicle body, a steel plate is usually welded on the front anti-collision bumper, connected to the front water spray rack mounting seat by bolts, or a separate "X"-shaped piece is buckled on the front bumper of the vehicle and then connected to the front water spray rack mounting seat. When welding is used to connect, the welding will damage the original front bumper of the vehicle; and when a separate "X"-shaped piece is used to connect the front bumper, the front bumper bears the weight of the front water spray rack and the vibration during operation. When the strength is insufficient, it will cause cracks at the connection position between the front anti-collision bumper bracket and the vehicle body longitudinal beam. Therefore, it is necessary to invent a new connection structure for the front water spray rack of a cleaning vehicle. Utility Model Content
