Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and more specifically, it relates to an aluminum profile automobile anti-collision beam. Background Technology

[0002] In automotive manufacturing production lines, where body assembly and collision safety system installation take place, anti-collision beams need to be precisely installed at designated positions at the front and rear ends of the vehicle to ensure that collision energy absorption performance and safety protection effects meet design requirements.

[0003] Existing methods for installing aluminum profile automotive crash beams mostly rely on manual visual alignment or positioning using pre-drilled mounting holes in the vehicle body. Manual visual alignment depends on the operator's experience in judging the relative position of the crash beam to components such as the longitudinal beams and energy-absorbing boxes. The positioning accuracy is greatly affected by human factors and is prone to lateral or height deviations. The installation process requires repeated adjustments to the position and verification with measuring tools to achieve the required assembly accuracy. While positioning using pre-drilled mounting holes in the vehicle body can determine the bolt connection positions, it cannot effectively constrain the posture and orientation of the crash beam before installation. During the process of transporting the crash beam to the installation position and aligning it with the mounting holes, it is prone to tilting or rotation, making it difficult to align the mounting holes or resulting in an incorrect installation angle for the crash beam after alignment. Operators need to support the weight of the crash beam while adjusting its posture and position, making the installation operation laborious and inefficient, and failing to meet the requirements of automotive production lines for fast and accurate installation and assembly cycle of crash beams. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides an aluminum profile automotive anti-collision beam to solve the technical problems mentioned in the background art. Technical solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile automotive anti-collision beam, comprising a beam body, an mounting bracket connected to the inner side of the beam body, multiple sets of mounting brackets, each with a fixed plate fixed at its top, and a positioning mechanism on each of the multiple sets of fixed plates. The positioning mechanism includes a rod and a fixing sleeve. The rod is inserted into the mounting plate, and the fixing sleeve is inserted into the top of the rod. The inner wall of the fixing sleeve has a movable groove, multiple sets of movable grooves, each with a slidingly connected locking block on its inner side, and a push spring connected between the outer side of each locking block and the movable groove. The outer wall of the rod has a locking groove, and an abutment block is fixedly provided at the bottom of the rod. An unlocking sleeve is slidably provided on the outer wall of the locking groove.

[0006] The present invention is further configured such that the inner sides of the multiple sets of card blocks are all set with inclined surfaces, and the outer wall of the unlocking sleeve is set with an inclined surface. The axial movement of the unlocking sleeve is converted into the radial movement of the card blocks through the cooperation of the inclined surfaces. The wedge-shaped force of the inclined surfaces pushes the card blocks to slide outward and disengage from the card slot, thereby reducing the operating force required for unlocking.

[0007] The present invention is further configured such that the outer wall of the abutment block is provided with a sliding groove, the sliding groove is provided in multiple sets and is slidably connected to a sliding sleeve, the bottom surface of the sliding sleeve is fixedly provided with a sliding rod, the top end of the sliding rod is fixedly connected to the unlocking sleeve, and the sliding groove provides a stable sliding guide for the sliding sleeve, and the sliding rod accurately transmits the pulling force of the sliding sleeve to the unlocking sleeve, thereby realizing reliable transmission from external rotation operation to internal unlocking block.

[0008] The present invention is further configured such that a sliding groove is provided on the outer wall of the insertion rod, and the sliding groove is slidably connected to the unlocking sleeve. The sliding groove provides accurate sliding guidance for the unlocking sleeve, ensuring that the unlocking sleeve moves smoothly along the axial direction without deviation, and restricting the circumferential rotation of the unlocking sleeve to ensure accurate pushing of multiple sets of locking blocks out of the slot.

[0009] The present invention is further configured such that a threaded sleeve is provided on the outer wall of the abutment block, and the rotational motion is converted into the linear motion of the sliding sleeve through the threaded sleeve to drive the unlocking mechanism to operate, making the operation simple and convenient.

[0010] The present invention is further configured such that each of the multiple sets of fixing plates is provided with a positioning hole, and the insertion rod is inserted into the positioning hole. The positioning hole and the insertion rod cooperate to provide a precise insertion position and guide channel, restrict the lateral movement of the insertion rod, and ensure accurate alignment between the fixing plate and the frame.

[0011] The present invention is further configured such that a thrust bearing is provided between the threaded sleeve and the sliding sleeve, and the thrust bearing bears the axial thrust generated when the threaded sleeve rotates, thereby reducing the rotational friction and making the rotational operation more effortless and smooth.

[0012] The present invention is further configured such that the outer side of the threaded sleeve is polygonal, and the polygonal structure facilitates rotational operation using a wrench or socket tool, and provides a reliable tool engagement surface to prevent slippage. Beneficial effects

[0013] Compared with the prior art, this utility model provides an aluminum profile automotive anti-collision beam, which has the following beneficial effects: 1. By setting a positioning mechanism on multiple sets of fixing plates, the insertion rod is inserted into the external frame and then into the positioning hole. Subsequently, the fixing sleeve is inserted into the top of the insertion rod. The insertion rod pushes multiple sets of locking blocks to slide into the movable groove and compresses multiple sets of push springs. When the insertion rod is fully inserted into the fixing sleeve, the multiple sets of push springs reset and push the locking blocks into the slots to complete the locking of the insertion rod, accurately positioning the fixing plate on the frame. The entire positioning process achieves precise alignment of the beam with the longitudinal beam of the vehicle body, energy absorption box and other components through the insertion and cooperation of the insertion rod and the frame. It does not require manual visual judgment or repeated adjustment and measurement confirmation, avoiding the problem of left and right offset or height deviation caused by human factors affecting the positioning accuracy of traditional installation methods.

[0014] 2. Multiple sets of push springs continuously push the locking blocks to engage in the slots, forming a reliable automatic locking mechanism. When the insertion rod is in place, the locking blocks automatically engage in the slots, achieving stable fixation of the beam on the vehicle frame. This eliminates the need for operators to use their hands or auxiliary support tools to lift the anti-collision beam to maintain its position, effectively solving the problems of traditional installation methods, such as the lack of temporary positioning and support mechanisms, the need for operators to lift the anti-collision beam while simultaneously tightening bolts, and the tendency for the anti-collision beam to sink or shift due to its own weight or operating force, leading to misalignment of the mounting holes.

[0015] 3. By rotating the threaded sleeve, the sliding sleeve is pulled along multiple sets of sliding grooves via the thrust bearing. The sliding sleeve pushes the unlocking sleeve along the sliding groove via the sliding rod. The unlocking sleeve pushes multiple sets of locking blocks to disengage from the locking groove through the interaction of the inclined plane, thus releasing the locking of the insertion rod. Then, the insertion rod is separated from the positioning hole to complete the disassembly of the positioning mechanism. The entire unlocking process can be quickly released by simply rotating the threaded sleeve, without the need to use tools to disassemble multiple connecting parts one by one or to forcefully pull out the insertion rod.
