Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of simulation device technology, and more specifically, to a vehicle collision and rear-end collision simulation device. Background Technology
[0002] Collisions and rear-end collisions are common car accidents. Before an accident, failure to wear a seatbelt, improper seating posture, or failure to assume a proper anti-collision stance when a collision is imminent can easily lead to bodily injury. Furthermore, failing to calm down after an accident can also easily cause secondary accidents. Collision or rear-end collision simulations can improve people's accident handling abilities and reduce personal injury.
[0003] Currently, most car simulation devices only offer the function of colliding with obstacles in front while the vehicle is in motion, used to experience the role of seat belts in a vehicle collision. They lack the function of simulating a rear-end collision with a stationary vehicle, thus failing to adequately meet simulation needs. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a vehicle collision and rear-end collision simulation device, which solves the technical problem that the simulation devices for automobiles in the related art do not have the function of simulating a vehicle being rear-ended while it is stationary, and thus cannot better meet the simulation requirements.

[0006] A vehicle for the simulator to ride in;
[0007] A stop, the stop being located at the front of the passenger vehicle;
[0008] A rear-end collision vehicle, located behind the passenger vehicle, is used to push the passenger vehicle toward the barrier and cause it to collide with the barrier, or to impact the passenger vehicle.

[0011] A hook is provided at the rear end of the passenger vehicle or at the front end of the vehicle involved in the rear-end collision.
[0012] The hanging device is raised and lowered at the front of the rear-end collision vehicle or the rear of the passenger vehicle. After being raised and lowered, the hanging device is used to hook and connect or detach from the hook.
[0013] For example, in a vehicle collision and rear-end collision simulation device provided in at least one embodiment of this disclosure, the vehicle collision and rear-end collision simulation device further includes a telescopic mechanism. One end of the telescopic mechanism is connected to the passenger vehicle, and the other end is connected to the hanging device. After the telescopic mechanism extends and retracts, it is used to drive the hanging device to rise and fall.
[0014] For example, in at least one embodiment of the vehicle collision and rear-end collision simulation device provided in this disclosure, the vehicle collision and rear-end collision simulation device further includes:
[0015] A limit switch, wherein the limit switch is disposed on the stop;
[0016] The control module has its input terminal electrically connected to the output terminal of the limit switch, and its output terminal is simultaneously electrically connected to both the rear-end collision vehicle and the telescopic mechanism.
[0017] For example, in at least one embodiment of the vehicle collision and rear-end collision simulation device provided in this disclosure, the vehicle collision and rear-end collision simulation device further includes:
[0018] A slide rail is provided on the passenger vehicle, and the slide rail is arranged along the vertical direction in its length direction.
[0019] A slider, which is in sliding engagement with the slide rail, and a hanger is mounted on the slider.
[0020] For example, in at least one embodiment of the vehicle collision and rear-end collision simulation device provided in this disclosure, the vehicle collision and rear-end collision simulation device further includes:
[0021] A frame, which is located behind the vehicle involved in the rear-end collision;
[0022] The main friction wheel is rotatably mounted on the frame, and its shaft is positioned in the left-right direction.
[0023] A secondary friction wheel is rotatably mounted on the frame, with its shaft positioned in the left-right direction. The secondary friction wheel is located in front of the primary friction wheel, and the secondary friction wheel and the primary friction wheel are connected by a steel wire rope wound between them. One end of the steel wire rope is used to connect to the rear-end collision vehicle.
[0024] For example, in a vehicle collision and rear-end collision simulation device provided in at least one embodiment of this disclosure, the vehicle collision and rear-end collision simulation device further includes a rotary drive mechanism, which is connected to the main friction wheel via a transmission.
[0025] For example, in a vehicle collision and rear-end collision simulation device provided in at least one embodiment of this disclosure, both the main friction wheel and the secondary friction wheel have receiving grooves on their circumferential surfaces, and the receiving grooves are used to receive the wire rope.

[0029] The beneficial effects of the embodiments disclosed herein are as follows: The passenger vehicle provides the simulator with a space similar to a real driving environment, allowing them to experience the sensations of vehicle collisions and rear-end collisions. A barrier is located in front of the passenger vehicle, acting as a collision obstacle. The rear-ending vehicle is located behind the passenger vehicle and serves two purposes: first, it pushes the passenger vehicle towards the barrier; after reaching a set position, the rear-ending vehicle stops moving, while the passenger vehicle continues to move towards the barrier under inertia and collides with it, simulating the passenger vehicle hitting the barrier in front; second, it directly impacts the passenger vehicle, simply simulating the instantaneous impact of a rear-end collision. Through these two methods, the simulator allows the simulator user to personally experience near-realistic collision and rear-end collision scenarios, better meeting simulation needs and allowing them to familiarize themselves with the sensations of an accident in advance, including the violent shaking of the vehicle and the impact force of the collision. After multiple simulation experiences, the simulator user is more likely to remain calm and react correctly when facing a real accident, such as correctly using a seatbelt and adopting a proper collision-resistance posture, thereby improving their ability to cope with accidents.

[0042] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0043] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0044] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0045] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0046] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0047] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0048] like Figures 1-2 As shown, it illustrates a vehicle collision and rear-end collision simulation device according to an embodiment of the present disclosure, including a passenger vehicle 1, a stop 2, and a rear-end collision vehicle 3. The passenger vehicle 1 is used for a simulator to ride in. The passenger vehicle 1 has a seat and a steering wheel. The seat is equipped with a seat belt, which can effectively restrain the simulator's body at the moment of collision and provide the simulator with a space similar to a real car riding environment, so that the simulator can experience the feeling of vehicle collision and rear-end collision in it.
[0049] The barrier 2 is located in front of the passenger vehicle 1; it acts as a collision obstacle. The barrier 2 is made of high-strength, high-toughness metal materials, such as special alloy steel, possessing sufficient strength to withstand the impact of the passenger vehicle 1 without excessive deformation or damage, simulating a real-world collision scenario between a vehicle and an obstacle. To increase stability, the bottom of the barrier 2 is securely connected to the ground or a specific foundation structure, for example, through anchor bolts or pre-embedded fasteners, ensuring it remains in a fixed position throughout multiple collisions.
[0050] The rear-end collision vehicle 3 is positioned behind passenger vehicle 1 and is used to either propel passenger vehicle 1 towards and collide with barrier 2, or to impact passenger vehicle 1. In other words, rear-end collision vehicle 3 has two functions: first, it propels passenger vehicle 1 towards barrier 2; after reaching a predetermined position, rear-end collision vehicle 3 stops moving, and passenger vehicle 1 continues to move towards barrier 2 under inertia, colliding with it—this simulates passenger vehicle 1 impacting barrier 2 in front; second, it directly impacts passenger vehicle 1, simply simulating the instantaneous impact of a rear-end collision. Through these two methods, simulators can experience near-realistic collision and rear-end collision scenarios, better meeting simulation needs and allowing them to familiarize themselves with the sensations of an accident, including the violent shaking of the vehicle and the impact force of the collision. After multiple simulations, simulators can remain calmer and more likely to react correctly in real accidents, such as properly using seat belts and adopting proper collision-resistance postures, thereby improving their ability to handle accidents.
[0051] In some examples, a vehicle collision and rear-end collision simulation device also includes a track 4, on which a passenger vehicle 1 and a rear-end collision vehicle 3 are slidably mounted, with a stop 2 located at the front end of the track 4.
[0052] For example, such as Figure 1 and Figure 2 As shown, track 4 is generally made of high-strength steel rails with a polished surface to reduce friction when the passenger vehicle 1 and the rear-end collision vehicle 3 slide, ensuring smooth vehicle operation. The bottom of track 4 is tightly connected to the ground via a series of fasteners, such as pre-embedded bolts and welded mounting brackets, ensuring that track 4 will not shift during multiple vehicle collisions. The passenger vehicle 1 and the rear-end collision vehicle 3 slide on track 4, which provides them with a fixed trajectory, making the simulation process more controllable and predictable. By restricting the direction of movement of the passenger vehicle 1 and the rear-end collision vehicle 3, the scenario of collisions and rear-end collisions when vehicles are traveling in a straight line on a real road can be simulated more accurately.
[0053] In some examples, a vehicle collision and rear-end collision simulation device also includes a hook 5 and a hanger 6. The hook 5 is located at the rear end of the passenger vehicle 1 or the front end of the rear-end collision vehicle 3. The hanger 6 is raised and lowered at the front end of the rear-end collision vehicle 3 or the rear end of the passenger vehicle 1. After the hanger 6 is raised and lowered, it is used to hook and connect or separate from the hook 5.
[0054] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, hook 5 is forged from high-strength metal materials, such as chromium-molybdenum alloy steel, and its strength and toughness are enhanced through heat treatment, enabling it to withstand greater tensile forces. The hook 5 is designed with a standard hook-like structure to ensure a secure connection with the hanger 6. Hanger 6 is also made of high-strength metal materials, and its shape and size match those of hook 5. Corresponding slots are provided on hanger 6 for easy hooking with hook 5. To ensure reliable connection, hook 5 is positioned at the front of the rear-end collision vehicle 3, and hanger 6 is positioned at the rear of the passenger vehicle 1. When it is necessary to pull passenger vehicle 1 back to its initial position, hanger 6 is lowered to hook and connect with hanger 5, and then the rear-end collision vehicle 3 pulls passenger vehicle 1 backward to its initial position. The structure is simple and easy to use.
[0055] In some examples, a vehicle collision and rear-end collision simulation device also includes a telescopic mechanism 7, one end of which is connected to the passenger vehicle 1 and the other end of which is connected to the hanging device 6. After the telescopic mechanism 7 extends or retracts, it is used to drive the hanging device 6 to rise or fall.
[0056] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the telescopic mechanism 7 can be an electric push rod, a hydraulic telescopic rod, or a pneumatic telescopic rod. In this disclosure, an electric push rod is preferred, which converts the rotational motion of the motor into the linear telescopic motion of the push rod.
[0057] The upper end of the telescopic mechanism 7 is connected to the passenger vehicle 1, and the lower end is connected to the hanging piece 6. The telescopic movement drives the hanging piece 6 to rise and fall. When it is necessary to pull the passenger vehicle 1 back to its initial position, the telescopic mechanism 7 extends, pushing the hanging piece 6 downwards to engage with the hook 5. When the rear-ending vehicle 3 pulls the passenger vehicle 1 backwards back to its initial position, the telescopic mechanism 7 retracts, pulling the hanging piece 6 upwards to separate it from the hook 5. This mechanized operation saves time and effort.
[0058] In some examples, a vehicle collision and rear-end collision simulation device also includes a limit switch 8 and a control module 9. The limit switch 8 is mounted on the stop 2. The input terminal of the control module 9 is electrically connected to the output terminal of the limit switch 8, and the output terminal of the control module 9 is simultaneously electrically connected to the rear-end collision vehicle 3 and the telescopic mechanism 7.
[0059] For example, such as Figure 7 and Figure 8As shown, the limit switch 8 is typically a high-precision, high-reliability mechanical or electronic limit switch. Mechanical limit switches sense the position of an object through a mechanical trigger mechanism, while electronic limit switches utilize photoelectric or electromagnetic principles to detect the approach or departure of an object. The limit switch 8 is mounted on the stop 2, and its trigger position is precisely calibrated to accurately detect whether the passenger vehicle 1 collides with the stop 2. The control module 9 generally uses a microcontroller (such as a single-chip microcomputer) or a programmable logic controller (PLC), possessing powerful data processing and control capabilities. It receives signals from the limit switch 8 and sends control commands to the telescopic mechanism 7 according to a preset program. When the passenger vehicle 1 collides with the stop 2, it triggers the limit switch 8 on the stop 2. The limit switch 8 transmits a signal to the control module 9. The control module 9 determines that a collision has occurred based on the received signal and then sends commands to the rear-end collision vehicle 3 and the telescopic mechanism 7. This causes the rear-end collision vehicle 3 to move behind the passenger vehicle 1, the telescopic mechanism 7 to extend, and the hanging piece 6 to descend and hook onto the hook 5 on the passenger vehicle 1. The rear-end collision vehicle 3 then pulls the passenger vehicle 1 backward back to its initial position. It can automate the simulation process, reduce human intervention, and improve the accuracy and reliability of the simulation.
[0060] In some examples, a vehicle collision and rear-end collision simulation device also includes a slide rail 10 and a slider 11. The slide rail 10 is mounted on the passenger vehicle 1 and its length direction is arranged in the vertical direction. The slider 11 is in sliding engagement with the slide rail 10, and the hanger 6 is mounted on the slider 11.
[0061] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the slide rail 10 adopts a high-precision linear guide rail, which has high hardness and wear resistance. The cooperation between the slide rail 10 and the slider 11 can provide stable and precise guidance for the lifting and lowering of the hanging part 6, ensuring that the hanging part 6 will not deviate or shake during the lifting and lowering process, ensuring the accuracy and reliability of the connection between the hook 5 and the hanging part 6, and making the lifting and lowering movement of the hanging part 6 more stable.
[0062] In some examples, a vehicle collision and rear-end collision simulation device also includes a frame 12, a main friction wheel 13, and a secondary friction wheel 14. The frame 12 is located behind the rear-end collision vehicle 3. The main friction wheel 13 is rotatably mounted on the frame 12, with its rotating shaft arranged in the left-right direction. The secondary friction wheel 14 is rotatably mounted on the frame 12, with its rotating shaft arranged in the left-right direction. The secondary friction wheel 14 is located in front of the main friction wheel 13. The secondary friction wheel 14 and the main friction wheel 13 are connected by a steel wire rope wound between them, and one end of the steel wire rope is used to connect to the rear-end collision vehicle 3.
[0063] For example, such as Figure 8 , Figure 9 and Figure 10As shown, the frame 12 is constructed of a high-strength metal frame, assembled by welding or bolting, possessing sufficient strength and stability to withstand the tension transmitted by the main friction wheel 13, the auxiliary friction wheel 14, and the wire rope. The surfaces of the main friction wheel 13 and the auxiliary friction wheel 14 have high hardness and wear resistance. At the moment of impact between the rear-ending vehicle 3 and the passenger vehicle 1, the traction force at the end of the wire rope increases dramatically. Since the wire rope has not yet rolled against the main friction wheel 13 and the auxiliary friction wheel 14, the overload traction force can cause the wire rope to slip against them, thus preventing the wire rope from breaking. The pressure of a single wire rope on the friction wheel is relatively small, and the contact area of a single wire rope with the friction wheel is small, insufficient to provide sufficient traction force. Multiple windings can increase the pressure, thereby increasing the upper limit of the traction force.
[0064] In some examples, a vehicle collision and rear-end collision simulation device also includes a rotary drive mechanism 15, which is drivenly connected to the main friction wheel 13.
[0065] For example, such as Figure 8 and Figure 9 As shown, the rotary drive mechanism 15 can be a power device such as a motor, reducer, or hydraulic motor. Taking a motor as an example, the motor is connected to the main friction wheel 13 through a coupling or pulley, transmitting the motor's rotational motion to the main friction wheel 14, providing rotational power to the main friction wheel 14, and enabling precise control of the rear-end collision vehicle 3. The control module 9, frame 12, main friction wheel 13, auxiliary friction wheel 14, and rotary drive mechanism 15 are all housed within the protective box 18, making them safer and more reliable, and resulting in a neater and more aesthetically pleasing overall appearance.
[0066] In some examples, both the main friction wheel 13 and the secondary friction wheel 14 have receiving grooves 1301 on their circumferential surfaces, which are used to receive the wire rope.
[0067] For example, such as Figure 10 As shown, the receiving groove 1301 is an annular groove machined on the circumferential surface of the main friction wheel 13 and the auxiliary friction wheel 14. Its shape is semi-circular or V-shaped, and the specific shape is designed according to the cross-sectional shape of the wire rope to ensure that the wire rope can fit tightly in the receiving groove 1301. This can prevent the wire rope from shifting or falling off during the rotation of the main friction wheel 13 and the auxiliary friction wheel 14, and ensure that the wire rope can stably transmit power, so as to realize the effective driving of the rear-end collision vehicle 3 by the main friction wheel 13 and the auxiliary friction wheel 14.
[0068] In some examples, the frame 12 has grooves 1201 on both the left and right sides. The length direction of the grooves 1201 is arranged along the front-to-back direction. A vehicle collision and rear-end collision simulation device also includes an adjusting seat 16 and an adjusting rod 17. The adjusting seat 16 is slidably engaged with the grooves 1201. The end of the auxiliary friction wheel 14 is rotatably connected to the adjusting seat 16. The adjusting rod 17 is rotatably connected to the frame 12 and threadedly connected to the adjusting seat 16. The length direction of the adjusting rod 17 is arranged along the front-to-back direction. After the adjusting rod 17 is rotated, it is used to move the adjusting seat 16 forward or backward along the grooves 1201.
[0069] For example, such as Figure 9 and Figure 10 As shown, the slide groove 1201 is a long strip-shaped groove machined on both sides of the frame 12, with its length direction along the front-to-back direction. The inner wall of the slide groove 1201 is ground to reduce the friction when the adjusting seat 16 slides within the slide groove 1201. The shape of the adjusting seat 16 matches the slide groove 1201, and a slider or roller is installed at the bottom to allow it to slide smoothly within the slide groove 1201. The adjusting rod 17 is usually a threaded rod and is rotatably connected to the frame 12. When the adjusting rod 17 is rotated, the rotational motion of the adjusting rod 17 is converted into linear motion of the adjusting seat 16 within the slide groove 1201, thereby driving the secondary friction wheel 14 to move back and forth. By adjusting the position of the secondary friction wheel 14, the tension of the wire rope can be changed to better meet the usage requirements.
