Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bumper cars, in particular to a collision buffer structure of a bumper car. Background Art
[0002] Bumper cars are a type of motorized amusement facility. The equipment includes bumper cars and an indoor venue. There is an electrified grid on the ceiling. There are small electric bumper cars for passengers to drive in the venue. The electric cars are connected to the vertical poles on the ceiling. Generally, there are two people on the car, with pedals for acceleration and steering wheels for steering.
[0003] Most of the existing bumper car collision buffer structures are composed of a single buffer structure that contracts forward and backward to buffer the collision impact force. When the bumper car is hit obliquely, the existing bumper car collision buffer structure cannot effectively absorb the lateral impact force, and the buffer structure that contracts forward and backward is prone to bending when subjected to lateral impact force for a long time. Utility Model Content
[0004] The utility model aims to provide a bumper car collision buffer structure to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bumper car collision buffer structure, including a bumper car chassis, collision shells are arranged at both ends of the bumper car chassis, a damping rod is hingedly installed between the collision shell and the bumper car chassis, a shrink sleeve is fixedly connected to a position inside the collision shell between the two damping rods, and the other end of the shrink sleeve is connected to the bumper boat chassis.
[0006] Preferably, the outer surfaces of the inner rod and the outer rod of the damping rod are both provided with limit plates, and the outer surface of the damping rod between the two limit plates is provided with a return spring. When one side of the collision shell is tilted after being hit by other bumper cars, the inner rod of the damping rod on the inner side of the collision end is contracted toward the inside of the outer rod, the return spring contracts, and the inner rod of the damping rod on the inner side of the other end is pulled outward, the return spring is stretched to absorb the impact force generated by the collision, and then the two return springs reset the damping rod to ensure that the collision shell and the bumper car chassis are in a parallel state.
[0007] Preferably, both side surfaces of the bumper car chassis are provided with rubber shells, which have a certain buffering effect and protect both sides of the bumper car chassis. If both sides of the bumper car are accidentally hit, the rubber shells can absorb a certain impact force.
[0008] Preferably, a cavity is provided inside the shrink sleeve, an inward-retracting bracket is provided at the front end of the cavity, the head end of the inward-retracting bracket is hingedly mounted on one side of the collision shell, a limit plate is provided at the bottom end of the inward-retracting bracket, a buffer spring is provided at the bottom end of the limit plate, and the limit plate serves to limit the length of the inward-retracting bracket extending outward. When the collision shell is hit in front, the inward-retracting bracket will shrink into the cavity, squeezing the buffer spring and reducing the impact force on the bumper car chassis. When the collision is over, the buffer spring will push the reset limit plate to reset the inward-retracting bracket.
[0009] Preferably, notches are provided on the surrounding surfaces of the inward-retracting bracket at the cavity position, tension springs are provided at the four notches, and extension plates are provided on the end surfaces of the four tension springs. When the inward-retracting bracket moves toward the inside of the shrinkage sleeve due to impact force, the four tension springs are stretched to further absorb the impact force and reduce the impact force on the bumper car base.
[0010] Preferably, the top surfaces of the four extension plates are fixedly mounted together inside the shrink sleeve, and the extension spring is installed at a predetermined position through the extension plate, thereby ensuring that the extension spring can further reduce the impact force on the bumper car base.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The bumper car collision buffer structure is used in combination with an inward-retracting bracket and a shrinking sleeve, and a damping rod and a return spring. When one side of the collision shell is hit by other bumper cars and tilts, the stressed inner rod of the damping rod inside the collision end shrinks toward the inside of the outer rod, the return spring shrinks, and the inner rod of the damping rod inside the other end is pulled outward, and the return spring is stretched to absorb the impact force generated by the collision. Then the two return springs reset the damping rod to ensure that the collision shell and the bumper car chassis are in a parallel state. When the collision shell is hit in front, the inward-retracting bracket will shrink into the cavity, squeeze the buffer spring, and reduce the impact force on the bumper car chassis. When the collision is over, the buffer spring will push the return limit plate to reset the inward-retracting bracket. A single buffer device has a poor effect in absorbing impact force. Buffer devices are set at different positions to absorb impact force to the maximum extent. At the same time, the bumper car shrinks or tilts at both ends when hit at different positions to reduce the impact force on the bumper car. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0019] like Figures 1 to 3 As shown, the present embodiment is a bumper car collision buffer structure, including a bumper car chassis 1, both ends of the bumper car chassis 1 are provided with a collision shell 4, when driving the bumper car, the collision shell 4 collides with other bumper cars to prevent the bumper car chassis 1 from being damaged by the impact force, a damping rod 5 is hingedly installed between the collision shell 4 and the bumper car chassis 1, a shrink sleeve 3 is fixedly connected between the two damping rods 5 and located at the inner side of the collision shell 4, the other end of the shrink sleeve 3 is connected to the bumper boat 1 chassis, when one side of the collision shell 4 is hit by other bumper cars and tilts, the damping rod 5 on the inner side of the collision end is stressed and the inner rod is contracted toward the inside of the outer rod, and the inner rod of the damping rod 5 on the inner side of the other end is pulled outward to absorb the impact force generated by the collision.
[0020] Specifically, the outer surfaces of the inner rod and the outer rod of the damping rod 5 are both provided with limit plates 6, and the outer surface of the damping rod 5 between the two limit plates 6 is provided with a return spring 7. When one side of the collision shell 4 is hit by other bumper cars and tilts, the inner rod of the damping rod 5 on the inner side of the collision end is contracted toward the inside of the outer rod, and the return spring 7 contracts. The inner rod of the damping rod 5 on the inner side of the other end is pulled outward, and the return spring 7 is stretched to absorb the impact force generated by the collision. Then the two return springs 7 reset the damping rod 5 to ensure that the collision shell 4 is in a parallel state with the bumper car chassis.
[0021] Furthermore, rubber shells 2 are provided on both side surfaces of the bumper car chassis 1. The rubber shells 2 have a certain buffering effect and protect both sides of the bumper car chassis 1.
