Abstract
Description
Technical Field
[0001] The utility model particularly relates to an abnormal drive guidance device used for testing the risk avoidance capability of a vehicle. Background Art
[0002] The name of the moose test comes from the animal, the elk. Found in Scandinavia in northern Europe and across much of North America, elk often inadvertently jump out in front of vehicles, colliding with high-speed vehicles and causing serious traffic accidents. The elk test is also used to test a vehicle's ability to avoid danger in an emergency. The elk test involves entering the test area at a constant speed with a fully loaded vehicle (four passengers, with the luggage compartment loaded with a corresponding weight), and performing high-speed evasive maneuvers without braking or accelerating. If there is no loss of control or rollover, the test vehicle's speed is gradually increased to determine the vehicle's limit. The test speed is based on the vehicle's own speedometer, and the final recorded speed of loss of control is the result of the elk test. This reflects the vehicle's ability to avoid danger in an emergency. During the test, pile barrels can be set up to block the vehicle and make an emergency lane change to avoid it. During the emergency lane change, the pile barrels are frequently knocked over, especially on gravel, ice and snow covered roads. The reset accuracy is lower and the time consumption is longer. After the pile barrel leaves its original position, the staff needs to restore the pile barrel in the shortest time possible to cooperate with the next elk test. However, due to the lack of standard guidance, a unified and standardized reset method cannot be implemented, resulting in low reset accuracy, affecting the accuracy of the test results. Utility Model Content
[0003] In order to overcome the defects of the prior art, a vehicle hazard avoidance capability test device is provided to solve the above problems.
[0004] The camshaft is mounted on a support frame, and the camshaft is mounted on a support frame. The camshaft is mounted on a support frame and has a plurality of control buttons. The camshaft is mounted on a support frame. The camshaft is mounted on a support frame. When the camshaft is mounted on the support frame, the control panel is turned on and off. The camshaft is then turned on and off. When the camshaft is turned on, the control panel is turned on and off.
[0005] The double-track support frame includes an upper blocking cover and two guide rods. The two guide rods are arranged vertically in parallel. A connecting blind hole is processed at the upper end of each guide rod. The upper blocking cover is a U-shaped plate. The two ends of the upper blocking cover are respectively detachably connected to the two connecting blind holes of the two guide rods.
[0006] The beneficial effects of the present invention are:
[0007] The utility model realizes the guidance process of restoring the pile bucket that deviates from the original position in the elk test in the shortest time through the mutual cooperation between the base, the lifting support rod and the multi-point indicator. After the multiple light beam guiding plates slide back and forth to the corresponding positions on the double-track support frame, the lamp body on the light beam guiding plate emits light, thereby illuminating the corresponding pile bucket top, bottom or other predetermined positions, ensuring that during the test, after the pile bucket deviates from the original position, the staff can restore the deviated pile bucket to the original position in the shortest time through the guidance of the light beam guiding plate and cooperate with the next test, which is conducive to improving the accuracy of the test results and standardizing and unifying the processing method for pile bucket restoration.

The front side of the support frame 5-1 is provided with a lamp body 5-2, and the back side of the support frame 5-1 is provided with two driving members 5-3. The power output shaft of each driving member 5-3 passes through the support frame 5-1 and is connected to its corresponding gear 5-4. Each gear 5-4 is engaged with the double-track support frame 4; the drive of the driving member 5-3 can not only start the driving force for the light beam guiding plate 5, but also realize the locking effect at the predetermined position by controlling the engagement of the gear 5-4 with the double-track support frame 4. The moving direction of the light beam guiding plate 5 is correspondingly controlled by the forward and reverse rotation of the driving member 5-3.
[0022] In this embodiment, the double-track support frame 4 includes an upper blocking cover 4-1 and two guide rods 4-2. The two guide rods 4-2 are arranged vertically in parallel. A connecting blind hole 4-3 is processed at the upper end of each guide rod 4-2. The upper blocking cover 4-1 is a U-shaped plate. The two ends of the upper blocking cover 4-1 are detachably connected to the two connecting blind holes 4-3 of the two guide rods 4-2.
[0023] Furthermore, the beam guiding plate 5 is a self-driven beam guiding plate. When conducting a moose test on a car, the light beam from each beam guiding plate 5 can be irradiated to the top, bottom or other predetermined positions of a corresponding pile bucket 11. During the process of starting the vehicle for testing, if it is found that a local pile bucket 11 is deviated from its original position, the position of the light beam emitted by the beam guiding plate 5 corresponding to the pile bucket 11 can be used as a reference to restore the pile bucket 11 to its initial position in the shortest time. When multiple beam guiding plates 5 are connected to the double-track support frame 4, the support frame 5-1 drives the gear 5-4 to slide back and forth between the two guide rods 4-2 through the driving member 5-3, ensuring that the light beam from the beam guiding plate 5 can be accurately irradiated to the top, bottom or other predetermined positions of the pile bucket 11 when adjusting the light beam, thereby improving the accuracy of the test results during the moose test.
[0024] Furthermore, multiple beam guiding plates 5 are mounted on two guide rods 4-2 through a support frame 5-1 to avoid slipping and instability, so that a rack 9 is set on the guide rod 4-2, and the gears 5-4 on the multiple beam guiding plates 5 are engaged with the rack 9, and the power output shaft of the driving member 5-3 drives the gear 5-4 to move up and down between the two guide rods 4-2.
[0025] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1. An annular protrusion 4-1-1 is processed on each end of the upper sealing cover 4-1, and an annular groove is processed on the inner hole wall of the blind hole 4-3. When the upper sealing cover 4-1 is connected to the guide rod 4-2, each annular protrusion 4-1-1 is snap-fitted with its corresponding annular groove.
[0026] Furthermore, when multiple beam guiding plates 5 are mounted on the guide rod 4-2, the annular protrusion 4-1-1 on the upper blocking cover 4-1 can be snap-fitted with the annular groove in the guide rod 4-2, thereby ensuring that the beam guiding plates 5 and the guide rod 4-2 can be easily disassembled and installed.
[0027] Specific embodiment three: This embodiment is a further limitation of specific embodiment one or two. The lifting support rod 2 is formed by multiple single tube bodies 2-1 that are sequentially connected from top to bottom. The outer diameters of the multiple single tube bodies 2-1 decrease from bottom to top. Adjacent single tube bodies 2-1 are connected in a sleeve manner. The interiors of the multiple single tube bodies 2-1 are sequentially connected to form a wiring cavity 6 that cooperates with multiple beam guiding plates 5.
[0028] Furthermore, the lifting support rod 2 can be extended and shortened through multiple single tubes 2-1, thereby ensuring that it can be easily retracted and extended during use. At the same time, a multi-point indicator 3 is provided at the upper end of the lifting support rod 2. The beam guiding plate 5 on the multi-point indicator 3 is a self-driven beam guiding plate. The light beam on the beam guiding plate 5 is irradiated on the top, bottom or other predetermined positions of the corresponding pile barrel 11, so that the interiors of the multiple single tubes 2-1 are connected in sequence to form a wiring cavity 6 that cooperates with the multiple beam guiding plates 5, providing a routing space for the lamp body 5-2 or other electronic control circuits, so that the entire structural form is reasonably configured and the space utilization rate is high, and no external accessories are required for routing components. The lamp body 5-2 is an existing lamp body that can emit laser beams, and its working principle is the same as that of the existing laser lamp body.
[0029] Specific embodiment four: This embodiment is a further limitation of specific embodiments one, two or three. The upper end of the lifting support rod 2 is detachably connected to the double-track support frame 4 in the multi-point indicator 3 through the connecting seat 7. The connecting seat 7 is a T-shaped seat body. The T-shaped seat body includes a vertical tube 3-1 and a horizontal tube 3-2. The vertical tube 3-1 is vertically arranged, and the horizontal tube 3-2 is horizontally arranged above the vertical tube 3-1. The middle part of the horizontal tube 3-2 is connected to the upper end of the vertical tube 3-1. The lower end of the vertical tube 3-1 is detachably connected to the lifting support rod 2, and the interior of the horizontal tube 3-2 is connected to the wiring cavity 6 through the vertical tube 3-1.
[0030] Furthermore, the lifting support rod 2 is connected to the double-track support frame 4 through the connecting seat 7. At the same time, during the connection process, the lifting support rod 2 and the connecting seat 7 can be inserted into the interior of the lifting support rod 2 through the vertical tube 3-1. The horizontal tube 3-2 on the vertical tube 3-1 is horizontally set at the top of the lifting support rod 2. During the connection process, the interior of the vertical tube 3-1 and the interior of the horizontal tube 3-2 are connected to the wiring cavity 6, thereby ensuring that the electric control circuit is stably connected to the lamp body 5-2 through the wiring cavity 6, forming a built-in wiring form, avoiding external interference, and helping to improve the stable use performance adapted to severe weather conditions.
[0031] Furthermore, a heat-insulating layer may be laid in the wiring cavity 6 or a heat-insulating cover may be wrapped around the lifting support rod 2 , so as to improve the self-protection performance of the present invention.
[0032] The lifting support rod 2 is an existing lifting rod body structure. It can form support forms of different heights by installing its own multi-section sleeves and then lifting and lowering between the sleeves. By tightening the inner sleeve with bolts, the outer sleeve and the inner sleeve can be fixed in relative position after lifting and lowering adjustment.
[0033] Specific embodiment five: This embodiment is a further limitation of specific embodiments one, two, three or four. Each guide rod 4-2 is processed with a strip-shaped notch 8 along its length direction, and a rack 9 is fixedly installed in the strip-shaped notch 8. The length direction of the rack 9 is in the same direction as the length direction of the rack 9, and the rack 9 is engaged with the gear 5-4.
[0034] Furthermore, the rack 9 is fixedly connected to the guide rod 4-2 through the strip-shaped notch 8, ensuring that when the support frame 5-1 is connected to the guide rod 4-2, the gear 5-4 can be driven by the driving member 5-3 to slide back and forth along the length direction of the guide rod 4-2, thereby ensuring the accuracy of the test results.
[0035] Specific embodiment six: This embodiment is a further limitation of specific embodiments one, two, three, four or five. When the two driving members 5-3 are replaced by one driving member 5-3, a counterweight block 10 that cooperates with the driving member 5-3 is provided on the support frame 5-1.
[0036] Furthermore, the first form is that two driving members 5-3 drive two gears 5-4 to perform reciprocating sliding motion on the guide rod 4-2, and the second form is that one driving member 5-3 drives the support frame 5-1 to perform reciprocating sliding motion on the guide rod 4-2. When one driving member 5-3 appears, in order to prevent the light beam guiding plate 5 from sliding on the double-track support frame 4 and tilting due to uneven weight distribution, a counterweight block 10 that matches the driving member 5-3 is provided on the support frame 5-1, thereby achieving a balanced state.
[0037] Specific embodiment seven: This embodiment is a further limitation of specific embodiments one, two, three, four, five or six, and the support frame 5 - 1 is a rectangular frame or a rectangular frame with a short notch.
[0038] Furthermore, the support frame 5-1 is a rectangular frame, ensuring that two driving members 5-3 or one driving member 5-3 and a counterweight 10 can be set on the support frame 5-1, so that the driving member 5-3 drives the gear 5-4 to slide back and forth on the guide rod 4-2. At the same time, a lamp body 5-2 is hinged on the support frame 5-1. By adjusting the light beam of the lamp body 5-2 to illuminate the original position of the pile bucket 11, the staff can restore the offset pile bucket 11 to its initial position under the guidance of the light beam, so as to cooperate with the next elk test and avoid affecting the accuracy of the test results.
[0039] The usage process of the present utility model is as follows: first, the staff installs the lifting support rod 2 on the base 1, installs the multi-point indicator 3 on the lifting support rod 2, and adjusts the position of multiple light beam guiding plates 5 on the double-track support frame 4 through the driving part 5-3, and uses the lamp body 5-2 to irradiate the light beam on the top, bottom or other predetermined positions of the corresponding pile bucket 11, so that when conducting the moose test, if a car knocks the pile bucket 11 off course, the staff can restore the pile bucket 11 to its original position in the shortest time through the position of the light beam irradiation, so that it can quickly cooperate with the next moose test.
[0040] The working principle of this utility model:
[0041] After placing the pile buckets 11 according to the formation form and size requirements, select the corresponding number of different-drive guidance devices for the vehicle hazard avoidance ability test for deployment, adjust each beam guidance plate 5 in the different-drive guidance device for the vehicle hazard avoidance ability test, and move multiple beam guidance plates 5 to their respective predetermined positions to ensure that the light beam of each beam guidance plate 5 is irradiated to the top, bottom or other predetermined positions of the corresponding pile bucket 11. When the vehicle is started for the elk test, when it is found that a local pile bucket 11 has deviated from its original position, the position of the pile bucket 11 is rearranged based on the position of the light beam emitted by the beam guidance plate 5 corresponding to the pile bucket 11. The placement principle is to ensure that the light beam of the beam guidance plate 5 is re-irradiated to the top, bottom or other predetermined positions of the pile bucket 11, thereby realizing the operation process of accurately and quickly re-arranging the pile bucket 11.
[0042] The specific process of selecting the corresponding number of different-drive guidance devices for the vehicle risk avoidance ability test for positioning is as follows: the standard formation is divided into two groups, that is, the pile buckets 11 corresponding to each side of the car are a group, each group of pile buckets 11 corresponds to a different-drive guidance device for the vehicle risk avoidance ability test, and the distance value between two adjacent pile buckets 11 in the formation is obtained. According to the angle between the top or bottom of each pile bucket 11 and the position of the lamp body 5-2 in its corresponding beam guiding plate 5, the vertical distance of the lamp body 5-2 is derived using the trigonometric function formula. The vertical position is the distance between the lamp body 5-2 and the vertical position of the lamp body 5-2. After determining the distance from each lamp body 5-2 to the bottom of the base 1, the distance from each lamp body 5-2 to the bottom of the base 1 is determined. This distance is the sum of the height of the base 1, the height of the lifting support rod 2 after adjustment, and the length from the top of the lifting support rod 2 to the lamp body 5-2. Each driving member 5-3 is then driven to synchronously or asynchronously adjust each beam directing plate 5 until each lamp body 5-2 moves to a predetermined position. The predetermined position is the vertical position of the lamp body 5-2 at a distance from the bottom of the base 1 that ensures that the light emitted by the lamp body 5-2 reaches the predetermined position of the corresponding bucket 11. Similarly, the vertical position of each lamp body 5-2 in the different-drive directing device for the vehicle hazard avoidance capability test corresponding to another set of buckets 11 is adjusted.
[0043] In this embodiment, the different drive guidance device can correspond to guiding multiple different formations, or it can correspond to guiding only one formation. It can also combine multiple different drive guidance devices for adjusting the vehicle's risk avoidance ability test and use them together to form a large span or other complex formation arrangement.
