Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, and specifically relates to an intelligent tail door stay rod. BACKGROUND

[0002] With the development and popularization of automobile technology, automobiles have increasingly entered ordinary households and gradually become a means of transportation for consumers to go to work and travel. With the rise in fuel prices, automobile lightweighting has been an important indicator in the development process of automobiles, and the miniaturization and lightweight design of component structures are one of the key indicators for measuring the quality of component development.

[0003] Currently, the traditional electric tail door stay rod on the market needs to use an external electronic control unit to control the electric opening and closing of the tail door. The stay rod needs to control the rotation of the DC motor inside the stay rod through the external electronic control unit, drive the lead screw to rotate through the gear box, and then drive the lead screw nut to move linearly to push the aluminum pipe and compression spring, thereby achieving the extension and retraction of the tail door stay rod.

[0004] The traditional electric tail door stay rod on the market mainly has the following shortcomings: 1. An external electronic control unit is needed to achieve the extension and retraction of the stay rod; 2. The connection between the external electronic control unit and the stay rod requires the use of complex connectors; 3. The stay rod can only output a Hall signal to the external electronic control unit and cannot provide more information, which is an information island.

[0005] For example, the Chinese patent CN119041789A discloses an automobile electric tail door stay rod, which includes a stay rod main body and a stay rod auxiliary body. One end of the telescopic stay rod main body is arranged on the automobile body, and the stay rod main body includes a first magnet. One end of the stay rod auxiliary body is arranged on the automobile tail door, and the stay rod auxiliary body includes a second magnet. The same magnetic poles of the first magnet and the second magnet are arranged in opposite intervals to enable the stay rod main body to support the automobile tail door through the repulsive force between the magnets. If an obstacle prevents the automobile tail door from closing during the retraction of the stay rod main body, the stay rod main body will not generate a traction force on the stay rod auxiliary body and the automobile tail door, and will not cause clamping of the obstacle. The automobile electric tail door stay rod provided by the present application effectively improves the reliability and safety of the automobile tail door stay rod. Although the electric tail door stay rod can reduce electric system circuit failures and thus cause sensor failure, the use of an external electronic control unit to achieve the extension and retraction of the stay rod increases the cost and complicates the assembly.

[0006] For example, a road noise control method, device, equipment and storage medium based on control of tail gate support rod are disclosed in Chinese Patent CN118979670A, which relates to the technical field of automobile NVH, and discloses a road noise control method based on control of tail gate support rod, which comprises the following steps: acquiring vibration acceleration of a tail gate in different directions collected by a preset sensor; calculating target vibration acceleration according to the vibration acceleration in the different directions; obtaining control current according to the target vibration acceleration and a preset vibration acceleration-current mapping table; and adjusting a motion parameter of a tail gate support rod of the vehicle according to the control current to complete road noise control of the tail gate support rod. Although the technical solution effectively reduces the noise in the vehicle caused by uneven road surface by collecting tail gate vibration data, calculating target vibration acceleration, and dynamically adjusting the motion parameter of the tail gate support rod by referring to the preset vibration acceleration-current mapping table, the design of the electric tail gate support rod cannot simplify the whole vehicle electrical connection and develop in the direction of informatization.
