Description

Technical Field

[0001] This utility model belongs to the technical field of front anti-collision beams, specifically an anti-collision front anti-collision beam assembly with adjustable width. Background Technology

[0002] The front crossbeam assembly is a key safety component at the front of a car. It typically consists of the crossbeam body, connecting brackets, and buffer structures. Its main function is to absorb and transfer collision energy during low-speed collisions or scrapes, reducing damage to core components such as the vehicle's longitudinal beams and engine. It also provides mounting support for exterior parts such as the front bumper and is an important component in ensuring the vehicle's safety performance and structural integrity.

[0003] In existing technologies, the width of the front crossbeam assembly is mostly a fixed design. Its size is determined during manufacturing based on the front structural parameters of a specific vehicle model, and cannot be flexibly adjusted according to actual usage needs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example 1, by Figure 1 The present invention relates to a front crossbeam assembly with adjustable width for collision protection, comprising a crossbeam body 1, wherein there are two crossbeam bodies 1, which are symmetrically arranged, and an adjustment mechanism 2 is provided between the two crossbeam bodies 1.

[0017] Specifically, by Figure 2-4The adjusting mechanism 2 includes a sleeve plate 201 located between two crossbeam bodies 1. A support shaft 208 is rotatably connected to the outer side of the sleeve plate 201. A handwheel 2011 is fixedly connected to the end of the support shaft 208 away from the sleeve plate 201. A sleeve disc 207 is fixedly sleeved on the outer side of the support shaft 208. Mounting columns 203 are fixedly connected to the outer sides of both crossbeam bodies 1. Two movable rods 202 are rotatably connected at equal angles to the side of the sleeve disc 207 away from the sleeve plate 201. The ends of the two movable rods 202 away from the sleeve disc 207 are rotatably connected to the two mounting columns 203 respectively. Multiple reinforcing columns 3 are provided on the outer side of the sleeve disc 207. The sleeve plate 201 is fixedly sleeved on the middle of the outer side of each reinforcing column 3. Both crossbeam bodies 1 are movably sleeved on the outer side of each reinforcing column 3. Two guide columns 2017 are symmetrically fixedly connected to the outer side of the sleeve plate 201. A sliding plate 204 is movably connected between the two guide posts 2017. A bracket 205 is fixedly connected to the side of the sliding plate 204 away from the sleeve plate 201. A side rod 206 is fixedly connected to the outside of the bracket 205. A limit plate 2010 is fixedly connected to the end of the side rod 206 away from the bracket 205. Multiple anti-slip particles 209 are provided on the side of the limit plate 2010 away from the side rod 206. Each anti-slip particle 209 abuts against the side of the handwheel 2011 away from the sleeve plate 207. A screw 2014 located between the two guide posts 2017 is fixedly connected to the outside of the sleeve plate 201. The sliding plate 204 is located outside the screw 2014 and does not contact the screw 2014. A screw cylinder 2013 is threadedly sleeved on the outside of the screw 2014. One end of the screw cylinder 2013 abuts against the side of the sliding plate 204 away from the sleeve plate 201. A turntable 2018 is fixedly connected to the other end of the screw cylinder 2013. In use, first rotate the handwheel 2011 to drive the support shaft 208 to rotate, and drive the sleeve 207 to rotate. Then, the two movable rods 202 drive the two mounting columns 203 to move respectively. At the same time, the two crossbeam bodies 1 slide along each reinforcing column 3. Then, push the slide plate 204 to slide along the two guide columns 2017, drive the bracket 205 to move, and drive the limiting plate 2010 to move through the side rod 206 until each anti-slip particle 209 is in close contact with the handwheel 2011. Then, rotate the turntable 2018 to drive the screw barrel 2013 to rotate and move outside the screw 2014 until the screw barrel 2013 abuts against the slide plate 204, thereby limiting the handwheel 2011 to prevent it from rotating arbitrarily. Finally, change the distance between the two crossbeam bodies 1 to adjust the width of the entire anti-collision front crossbeam.

[0018] Specifically, by Figure 4 As shown, side plates 2012 are fixedly connected to the outer sides of the two crossbeam bodies 1. Multiple insertion holes 2016 are provided at equal intervals on the outer sides of the two side plates 2012. Two insertion rods 2015 are symmetrically fixedly connected to the outer side of the slide plate 204. The two insertion rods 2015 are respectively inserted into the two corresponding insertion holes 2016. In use, when the skateboard 204 slides along the two guide posts 2017 and moves the limiting plate 2010, the two insert rods 2015 move. When all the anti-slip particles 209 are in close contact with the handwheel 2011, the two insert rods 2015 are inserted into the two corresponding insertion holes 2016 respectively, which further ensures the stability of the two crossbeam bodies 1 and prevents them from loosening.
