Description

Technical Field

[0001] This utility model relates to the field of bumper car technology, specifically a protective device for bumper cars. Background Technology

[0002] Bumper cars, a popular amusement ride, are widely used in amusement parks, theme parks, and other entertainment venues. They provide a fun and exciting experience through collisions between the vehicles. During these collisions, the safety of occupants and the structural protection of the vehicles themselves are among the core design considerations. With the continuous improvement of safety standards for amusement facilities, optimizing protective performance and reducing damage to occupants and vehicles from collisions while ensuring a safe and enjoyable experience has become an important research direction in the field of bumper car technology.

[0003] Currently, most common bumper car safety devices on the market rely on rubber buffer strips on the outside of the vehicle. These devices typically work by absorbing collision energy through the deformation of elastic materials. For example, rubber rings are placed around the edges of the vehicle to offset some of the impact force, thereby reducing the impact on the vehicle and occupants to a certain extent. Existing technology uses a single structure of rubber buffer strips for protection, which has the problem of limited collision energy absorption efficiency. Especially in high-intensity collisions, it is difficult to quickly attenuate the impact force, making occupants susceptible to shock or even minor injuries. The stability and durability of the protective effect are also poor. Therefore, we propose a bumper car safety device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a protective device for bumper cars. The multi-level buffer structure improves safety and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for bumper cars, including a car body and a protective mechanism;

[0006] The protective mechanism includes a mounting frame, a friction barrel, a mounting post, and a first hydraulic damper. The mounting frame is located at the front interior of the vehicle body, and the friction barrel is located on the rear inner wall of the mounting frame. The mounting post is slidably connected to the front interior of the friction barrel, and its front end passes through a through hole at the front end of the vehicle body. A rubber protective rod is rotatably connected to the front end of the mounting post. The first hydraulic damper is located on the rear inner wall of the friction barrel, and its damping end is fixedly connected to the rear side of the mounting post. Through a multi-stage buffer structure, the collision impact force of the bumper car is absorbed in three dimensions and dynamically protected, improving safety and adaptability.

[0007] Furthermore, the protective mechanism also includes a buffer rod and a movable frame. U-shaped seats are provided on both the left and right sides of the middle of the outer arc surface of the mounting column, and strip openings are provided on both the left and right sides of the middle of the friction barrel. The U-shaped seats are located inside the horizontally adjacent strip openings, and buffer rods are rotatably connected inside the U-shaped seats. The movable frame is respectively set on the left and right inner walls of the mounting frame through damping components. The rear end of the buffer rod is rotatably connected to the front end of the adjacent movable frame on the rear side for buffering.

[0008] Furthermore, the damping component is a second hydraulic damper, and the left and right inner walls of the mounting frame are provided with second hydraulic dampers. The movable frame is fixedly connected to the damping end of the second hydraulic damper that is laterally adjacent to absorb the impact force.

[0009] Furthermore, a third hydraulic damper is installed at both ends of the bottom wall of the mounting bracket, and a sliding groove is opened at both ends of the rear arc surface of the rubber guard rod. A slider is slidably connected between the upper and lower inner walls of the sliding groove. The telescopic ends of the third hydraulic damper pass through the sliding hole opened on the front side of the vehicle body and are fixedly connected to the rear end of the outer arc surface of the adjacent slider on the front side. It can rotate within a certain range to better protect against multi-angle impacts.

[0010] Furthermore, a microcontroller is provided on the rear inner wall of the mounting bracket, and the input terminal of the microcontroller is electrically connected to an external power supply for easy data analysis.

[0011] Furthermore, the outer arc surface of the mounting column is provided with a mounting plate at its rear end. The middle part of the mounting plate is located inside the horizontally adjacent strip opening. A laser rangefinder is provided on the rear side of the mounting plate. The laser rangefinder is bidirectionally electrically connected to the microcontroller. The laser rangefinder is configured to cooperate with the rear inner wall of the mounting frame to monitor the displacement distance of the mounting column in real time.

[0012] Furthermore, a rubber impact ring is provided at the lower end of the vehicle body for protection.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The protective device for this bumper car has the following advantages:

[0014] The multi-stage buffer structure achieves three-dimensional absorption and dynamic protection against collision impact, significantly improving safety and adaptability. Specifically, when the rubber guard bar is subjected to collision force, the mounting column compresses the first hydraulic damper backward, using the flow of hydraulic oil to consume energy and slow down the impact speed. At the same time, the friction barrel wall comes into contact with the mounting column to generate friction, converting the collision kinetic energy into heat energy to reduce the impact intensity. When the mounting column moves, it pushes the buffer rod, which drives the moving frame to compress the second hydraulic damper. The hydraulic system absorbs the lateral impact force. When the rubber guard bar is passively rotated due to a side impact, the slider slides in the groove, causing the third hydraulic damper to contract, absorbing the impact force with the help of the hydraulic system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: a protective device for a bumper car, including a car body 1, a rubber collision ring 10 at the lower end of the car body 1, the rubber collision ring 10 at the lower end of the car body deforms during a collision, absorbs the ground reaction force and bottom impact energy, and reduces the impact of the vibration of the car body 1 on passengers, and also includes a protective mechanism 2.

[0023] Protective mechanism 2 includes a mounting frame 21, a friction barrel 22, a mounting post 23, and a first hydraulic damper 24. The mounting frame 21 is located at the front end of the vehicle body 1. The friction barrel 22 is located on the rear inner wall of the mounting frame 21. The mounting post 23 is slidably connected to the front end of the friction barrel 22. The front end of the mounting post 23 passes through a through hole at the front end of the vehicle body 1. A rubber protective rod 3 is rotatably connected to the front end of the mounting post 23. The first hydraulic damper 24 is located on the rear inner wall of the friction barrel 22. The damping end of the first hydraulic damper 24 is fixedly connected to the rear side of the mounting post 23. The protective mechanism 2 also includes a buffer rod 25 and a movable frame 26. U-shaped seats 231 are provided on both the left and right sides of the middle of the outer arc surface of the mounting post 23. Strip-shaped openings are provided on both the left and right sides of the middle of the friction barrel 22. 221 and U-shaped seats 231 are both located inside the horizontally adjacent strip openings 221. A buffer rod 25 is rotatably connected inside each U-shaped seat 231. Moving frames 26 are respectively installed on the left and right inner walls of the mounting frame 21 via damping components. The rear ends of the buffer rods 25 are rotatably connected to the front ends of the adjacent moving frames 26. The damping components are second hydraulic dampers 11. Second hydraulic dampers 11 are provided on the left and right inner walls of the mounting frame 21. Moving frames 26 are fixedly connected to the damping ends of the horizontally adjacent second hydraulic dampers 11. Third hydraulic dampers 6 are installed on both the left and right ends of the bottom wall of the mounting frame 21. Slide grooves 4 are opened on both the left and right ends of the rear arc surface of the rubber protective rod 3. Sliding sliders 5 are slidably connected between the upper and lower inner walls of the slide grooves 4. The third hydraulic dampers 6... The telescopic ends all pass through the sliding holes opened on the front side of the vehicle body 1 and are fixedly connected to the rear end of the outer arc surface of the adjacent slider 5 on the front side. A microcontroller 9 is provided on the rear inner wall of the mounting bracket 21. The input end of the microcontroller 9 is electrically connected to an external power source. A mounting plate 7 is provided on the rear end of the outer arc surface of the mounting column 23. The middle part of the mounting plate 7 is located inside the horizontally adjacent strip opening 221. A laser rangefinder 8 is provided on the rear side of the mounting plate 7. The laser rangefinder 8 is bidirectionally electrically connected to the microcontroller 9. The laser rangefinder 8 is set in conjunction with the rear inner wall of the mounting bracket 21. When driving the bumper car, when the rubber guard bar 3 at the front of the vehicle body 1 is subjected to a frontal collision force, the force is transmitted to the friction barrel 22 through the mounting column 23. The mounting column 23 compresses the first hydraulic damper 24 backward. The first hydraulic damper 24 passes through... The flow of internal hydraulic oil consumes collision energy and slows down the impact speed. When the mounting column 23 slides inside the friction barrel 22, the contact between the barrel wall of the friction barrel 22 and the column body of the mounting column 23 generates friction, further converting the collision kinetic energy into heat energy and reducing the impact intensity. At the same time, the mounting column 23 moves backward through the U-shaped seat 231 at the strip opening 221, simultaneously pushing the buffer rod 25 to move backward in sync. The backward movement of the buffer rod 25 transmits the vertical impact force of the mounting column 23 to the adjacent second hydraulic damper 11 through the moving frame 26. The second hydraulic damper 11 consumes collision energy and slows down the impact speed through the flow of internal hydraulic oil, thereby absorbing the vertical impact force of the mounting column 23 from both vertical and lateral perspectives. Meanwhile, when the rubber protective rod 3 is impacted from the side...The impacted end of the rubber guard bar 3 rotates backward, causing the slider 5 at that end to slide within the groove 4, pushing the adjacent third hydraulic damper 6 to contract. The third hydraulic damper 6 absorbs the impact force through its internal hydraulic system. During this process, the laser rangefinder 8 monitors the displacement of the mounting column 23 in real time and transmits the data to the microcontroller 9. The microcontroller 9 determines the collision intensity based on the displacement. If the threshold is exceeded, the microcontroller 9 sends an alarm signal indicating excessive collision to the worker's terminal via its internal wireless communication module (the number of protective mechanisms 2 and rubber guard bars 3 can be increased depending on the application scenario). This multi-level buffer structure achieves three-dimensional absorption and dynamic protection against the impact force of the bumper car collision, improving safety and adaptability.

[0024] The working principle of the bumper car protective device provided by this utility model is as follows: When the bumper car is being driven, when the rubber protective bar 3 at the front of the car body 1 is subjected to a frontal collision force, the force is transmitted to the friction barrel 22 through the mounting column 23. The mounting column 23 compresses the first hydraulic damper 24 backward. The first hydraulic damper 24 consumes the collision energy and slows down the impact speed through the flow of internal hydraulic oil. When the mounting column 23 slides in the friction barrel 22, the contact between the barrel wall of the friction barrel 22 and the column body of the mounting column 23 generates friction, further converting the collision kinetic energy into heat energy and reducing the impact intensity. At the same time, the mounting column 23 moves backward through the U-shaped seat 231 at the strip opening 221, pushing the buffer rod 25 to move backward synchronously. The backward movement of the buffer rod 25 transmits the vertical impact force of the mounting column 23 to the adjacent second hydraulic damper 11 through the moving frame 26. The pressure damper 11 consumes collision energy and slows down the impact speed by flowing internal hydraulic oil, thereby absorbing the vertical impact force of the mounting column 23 from both vertical and lateral perspectives. At the same time, when the rubber guard bar 3 is hit from the side, the end of the rubber guard bar 3 that is hit rotates backward, and the slider 5 at this end slides in the groove 4, pushing the adjacent third hydraulic damper 6 to contract. The third hydraulic damper 6 absorbs the impact force through its internal hydraulic system. During this process, the laser rangefinder 8 monitors the displacement of the mounting column 23 in real time and transmits it to the microcontroller 9. The microcontroller 9 judges the collision intensity based on the displacement. If it exceeds the threshold, the microcontroller 9 sends an alarm signal of excessive collision to the staff terminal through its internal wireless communication module. The rubber collision ring 10 at the bottom of the vehicle body deforms during the collision, absorbing the ground reaction force and the bottom impact energy, reducing the impact of the vehicle body 1 vibration on the passengers.

[0025] It is worth noting that the laser rangefinder 8 disclosed in the above embodiments can be the TIM551 series, and the microcontroller 9 can be the ESP8266 series module (core processor ESP8266).

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
