Description

Technical Field

[0001] This invention relates to the field of vehicle testing technology, and more specifically, to a vehicle emergency braking testing device. Background Technology

[0002] Intelligent driving field testing is one of the important means of testing and evaluating the intelligent driving functions of vehicles. The testing of emergency braking functions and performance of vehicles is highly dangerous, and can easily cause damage to the vehicle and greatly threaten the lives of drivers and passengers. Therefore, it is often conducted in closed fields.

[0003] In regulatory tests for vehicle emergency braking (AEB) (CNCAP, ENCAP, etc.), the vehicle-to-vehicle test scenarios cover target vehicle stationary (CCRS), target vehicle creeping (CCRM), and target vehicle decelerating (CCRB). The speeds are typically high, especially in performance tests, where the vehicle's speed often exceeds 80 km / h. The industry commonly uses dummy vehicles (compliant with ISO 19206-3 requirements) as target vehicles. Their role in the testing process is the same as that of a real vehicle, but they can be reused, and in the event of a collision, they cause less injury to the vehicle and its occupants.

[0004] Therefore, how to provide a vehicle emergency braking test device has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] One objective of this invention is to provide a new technical solution for a vehicle emergency braking test device.

[0007] The supporting component includes a base plate, a fixed plate, two limiting plates, and wheels. The base plate is vertically connected to the fixed plate. The two limiting plates are arranged close to both sides of the fixed plate, and the first end of the limiting plate is connected to the fixed plate. The wheels are rotatably mounted on the second end of the limiting plates. The limiting plates and the base plate are on the same horizontal plane. The base plate is used to place a dummy car.

[0008] The two ends of the support component are respectively connected to the limiting plate and the fixing plate;

[0009] The base plate is slidably mounted on the fixing component, and the two limiting plates are located on both sides of the fixing component.

[0012] Optionally, the load-bearing assembly further includes two openings and rollers, with the two openings respectively disposed on the base plate and the rollers rotatably disposed within the openings.

[0013] Optionally, the base plate is provided with anti-slip texture.

[0014] Optionally, the support assembly includes a connecting plate, a first support rod, a second support rod, and a third support rod. The two ends of the connecting plate are respectively connected to the second ends of the two limiting plates. The first support rod and the second support rod are located on the outer side of the wheel, and the third support rod is located on the inner side of the wheel. The two ends of the first support rod, the two ends of the second support rod, and the two ends of the third support rod are respectively connected to the top of the connecting plate and the fixing plate.

[0015] Optionally, the length of the connecting plate is less than the width of the fixing plate, and the support assembly further includes a fixing frame located on both sides of the connecting plate, with both ends of the fixing frame connected to the bottom of the connecting plate and the fixing plate, respectively.

[0016] Optionally, the fixing assembly includes a first fixing rod, a second fixing rod, multiple reinforcing ribs, and a connecting rod.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention solves the problem of collision risks that could lead to injuries to people, vehicles, and dummy vehicles during AEB testing. Two limiting plates are positioned near the sides of the fixed plate, with the first end of each limiting plate connected to the fixed plate. Wheels are rotatably mounted on the second end of each limiting plate. The limiting plates and the base plate are on the same horizontal plane. Both ends of a support assembly are connected to the limiting plates and the fixed plate, respectively. The base plate is slidably mounted on the fixed assembly, with the two limiting plates located on either side of the fixed assembly. During testing, the operator positions the limiting plates on either side of the fixed assembly and places the target dummy vehicle on the base. When the target dummy vehicle is impacted, the impact causes the base plate to move on the fixed assembly, causing the wheels to roll on it. This effectively reduces the collision damage caused by AEB failure and mitigates the risk of injury to people, vehicles, and dummy vehicles during AEB testing.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a vehicle emergency braking test device, including: a dummy vehicle 1, a fixing component 2, a support component 3, and a load-bearing component 4.

[0031] The supporting component 4 includes a base plate 41, a fixing plate 42, two limiting plates 43 and wheels 44. The base plate 41 is vertically connected to the fixing plate 42. The two limiting plates 43 are arranged close to the two sides of the fixing plate 42, and the first end of the limiting plate 43 is connected to the fixing plate 42. The wheels 44 are rotatably arranged at the second end of the limiting plate 43. The limiting plate 43 and the base plate 41 are on the same horizontal plane. The base plate 41 is used to place the dummy car 1.

[0032] The two ends of the support component 3 are connected to the limiting plate 43 and the fixing plate 42, respectively.

[0033] The base plate 41 is slidably mounted on the fixed component 2, and the two limiting plates 43 are located on both sides of the fixed component 2.

[0034] During the test, the operator positioned the limiting plate 43 on both sides of the fixing component 2 and placed the target dummy car 1 on the base. When the target dummy car 1 was hit, the impact caused the base plate 41 to move on the fixing component 2, causing the wheels 44 to roll on the fixing component 2.

[0035] During static testing (CCRS), load-bearing component 4 can be used independently.

[0036] During deceleration and slow speed (ccrm, ccrb) tests, the target dummy car 1 is placed on the fixed component 2 and the vehicle tows the fixed component 2. When a collision occurs, the target dummy car 1 slides along the fixed component 2, and the vehicle towing in front can also accelerate to escape in time, effectively reducing the collision damage caused by the failure of the AEB function.

[0037] This invention solves the problem of collision risks that may occur during AEB testing, which could lead to injuries to people, vehicles, and the dummy car 1. Two limiting plates 43 are positioned close to both sides of the fixed plate 42, with the first end of each limiting plate 43 connected to the fixed plate 42. Wheels 44 are rotatably mounted on the second end of each limiting plate 43. The limiting plates 43 and the base plate 41 are on the same horizontal plane. Both ends of the support assembly 3 are connected to the limiting plates 43 and the fixed plate 42, respectively. The base plate 41 is slidably mounted on the fixed assembly 2, and the two limiting plates 43 are located on both sides of the fixed assembly 2. During testing, the operator positions the limiting plates 43 on both sides of the fixed assembly 2 and places the target dummy car 1 on the base. When the target dummy car 1 is impacted, the impact causes the base plate 41 to move on the fixed assembly 2, causing the wheels 44 to roll on the fixed assembly 2. This effectively reduces the collision damage caused by AEB failure and mitigates the risk of injury to people, vehicles, and the dummy car 1 during AEB testing.

[0038] The base plate 41 of the present invention has multiple fixed points, which can be used to place multiple models. It can be used as a testing device for other target objects such as dummies and two-wheeled vehicle models, thereby realizing scene testing of multiple target objects.

[0039] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2 As shown, the supporting component 4 also includes a first reinforcing plate 45 and a second reinforcing plate 46. The first reinforcing plate 45 and the second reinforcing plate 46 are respectively disposed at the bottom and top of the fixed plate 42, and the first reinforcing plate 45 is connected to the first end of the limiting plate 43, and the second reinforcing plate 46 is connected to the supporting component 3.

[0040] The present invention provides a first reinforcing plate 45 and a second reinforcing plate 46 respectively at the bottom and top of a fixed plate 42, and connects the first reinforcing plate 45 to the first end of a limiting plate 43 and the second reinforcing plate 46 to a support assembly 3. The first reinforcing plate 45 and the second reinforcing plate 46 increase the structural strength of the vehicle emergency braking test device of the present invention, reduce the injury to people and vehicles in AEB tests, and extend the service life of the dummy vehicle 1.

[0041] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2 As shown, the supporting component 4 also includes a baffle 47, which has a semi-circular structure. The baffle 47 is connected to the top of the fixing plate 42, and the interior of the baffle 47 faces the limiting plate 43.

[0042] Specifically, the target dummy car 1 can be connected and fixed to the baffle 47 by straps, so that the target dummy car 1 will not roll over and cause damage when it is hit.

[0043] The curved outer edge of the baffle 47 is set outwards, further reducing the risk of damage to people and dummy vehicle 1 after a collision.

[0044] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2 As shown, the supporting component 4 also includes two openings 48 and a roller 49. The two openings 48 are respectively disposed on the base plate 41, and the roller 49 is rotatably disposed in the openings 48.

[0045] The present invention provides two openings 48 respectively on the base plate 41, and a roller 49 is rotatably disposed in the openings 48, so that the base plate 41 can be moved on the fixing component 2 by means of the roller 49.

[0046] In one embodiment of the vehicle emergency braking test device of the present invention, the base plate 41 is provided with anti-slip texture. This configuration increases the coefficient of friction between the target dummy vehicle 1 and the base plate 41, thereby improving stability.

[0047] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2 As shown, the support assembly 3 includes a connecting plate 31, a first support rod 32, a second support rod 33, and a third support rod 34. The two ends of the connecting plate 31 are respectively connected to the second ends of the two limiting plates 43. The first support rod 32 and the second support rod 33 are located on the outside of the wheel 44, and the third support rod 34 is located on the inside of the wheel 44. The two ends of the first support rod 32, the two ends of the second support rod 33, and the two ends of the third support rod 34 are respectively connected to the top of the connecting plate 31 and the fixing plate 42.

[0048] Specifically, the first support rod 32, the second support rod 33 and the third support rod 34 are in two sets, each set being disposed on both sides of a wheel 44.

[0049] This invention, by placing the first support rod 32 and the second support rod 33 on the outside of the wheel 44 and the third support rod 34 on the inside of the wheel 44, and connecting the two ends of the first support rod 32, the two ends of the second support rod 33 and the two ends of the third support rod 34 to the top of the connecting plate 31 and the fixing plate 42 respectively, further increases the structural strength between the fixing plate 42 and the limiting plate 43, further reduces the injury to people and vehicles in the AEB test, and extends the service life of the dummy vehicle 1.

[0050] Furthermore, the present invention enables dynamic scene testing through support component 3.

[0051] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2As shown, the length of the connecting plate 31 is less than the width of the fixing plate 42. The support assembly 3 also includes a fixing frame 35, which is located on both sides of the connecting plate 31. The two ends of the fixing frame 35 are respectively connected to the bottom of the connecting plate 31 and the fixing plate 42.

[0052] The present invention improves the service life of the vehicle emergency braking test device by placing the fixing frame 35 on both sides of the connecting plate 31 and connecting the two ends of the fixing frame 35 to the bottom of the connecting plate 31 and the fixing plate 42 respectively, thereby forming a triangular structure with the first reinforcing plate 45 and the limiting plate 43.

[0053] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2 As shown, the fixing component 2 includes a first fixing rod 21, a second fixing rod 22, multiple reinforcing ribs 23, and a connecting rod 24. The connecting rod 24 is respectively disposed at both ends of the first fixing rod 21 and the second fixing rod 22, and both ends of the connecting rod 24 are respectively connected to the first fixing rod 21 and the second fixing rod 22. The multiple reinforcing ribs 23 are interconnected and bent. Both ends of the reinforcing ribs 23 are connected to the first fixing rod 21 and the second fixing rod 22. The inner wall of the limiting plate 43 abuts against the outer wall of the first fixing rod 21 and the outer wall of the second fixing rod 22. The wheel 44 is located between the first fixing rod 21 and the second fixing rod 22.

[0054] This invention connects the two ends of the connecting rod 24 to the first fixed rod 21 and the second fixed rod 22 respectively, and connects multiple reinforcing ribs 23 to each other in a bent configuration. The two ends of the reinforcing ribs 23 are connected to the first fixed rod 21 and the second fixed rod 22. In use, the inner wall of the limiting plate 43 abuts against the outer walls of the first fixed rod 21 and the second fixed rod 22, thereby providing a limiting effect on the base plate 41. This allows the base plate 41 to move along the length direction of the first fixed rod 21 and the second fixed rod 22, and positions the wheel 44 between the first fixed rod 21 and the second fixed rod 22, thereby improving the stability of vehicle movement.

[0055] In one embodiment of the vehicle emergency braking test device of the present invention, such as Figure 1 and Figure 2 As shown, the fixing component 2 also includes rollers 25, which are respectively disposed on the inner walls of the first fixing rod 21 and the second fixing rod 22. This arrangement facilitates the movement of the first fixing rod 21 and the second fixing rod 22, improving convenience.

[0056] In one embodiment of the vehicle emergency braking test device of the present invention, the fixing component 2 further includes a mounting plate, which is respectively disposed on the inner wall of the first fixing rod 21 and the second fixing rod 22 and located above the rolling wheel 25, with the wheel 44 located on the mounting plate.

[0057] The present invention enables the wheel 44 to move stably on the mounting plate by respectively setting the mounting plate on the inner wall of the first fixing rod 21 and the second fixing rod 22, and placing the mounting plate above the rolling wheel 25 and the wheel 44 on the mounting plate.
