This invention belongs to the field of vehicle safety technology and discloses a constant-resistance buffer vehicle energy-absorbing box, including a support tube, a collapsible tube, a pressure-reinforcing spherical crown, and a radial constriction tube. The support tube is slidably connected inside the collapsible tube, and the end of the support tube near the collapsible tube receives the pressure-reinforcing spherical crown, with the support tube and the pressure-reinforcing spherical crown in spherical contact. The inner diameter of the pressure-reinforcing spherical crown is a variable-diameter through hole. The end of the collapsible tube away from the support tube is connected to the radial constriction tube. The other end of the radial constriction tube is interference-fitted to the variable-diameter through hole. The inner collapsible tube structure of this invention can withstand a certain amount of off-center impact. After exceeding the bearing capacity of the inner collapsible tube structure, the radial constriction tube and the pressure-reinforcing spherical crown can bend and deflect with the collapsible tube, and the radial constriction tube and the pressure-reinforcing spherical crown can also remain coaxially aligned, ensuring that the radial constriction tube undergoes constant-resistance deformation after passing through the pressure-reinforcing spherical crown and does not get stuck. The constant-resistance deformation buffer of the vehicle energy-absorbing box generates minimal support reaction force, minimizing damage to people and vehicles, and greatly improving the passive safety of the vehicle.
