Description

Technical Field

[0001] The present invention relates to the technical field of vehicle collision testing, and in particular to a positioning device for a first collision point of a vehicle. Background Art

[0002] In a full-vehicle crash test, the first point of impact is the point where the test vehicle first contacts the collision barrier. Currently, there are two main methods for locating the first point of impact. One method involves positioning the test vehicle just in front of the collision barrier before the test. The vehicle is centered relative to the towing track, with the steering wheel positioned so that the vehicle can travel along the towing track. The vehicle is then pushed forward until it makes contact with the barrier. This point of contact is considered the first point of impact. The other method involves determining the first point of impact without the aid of a collision barrier, relying solely on the tester's intuition and experience to roughly determine the first point of impact.

[0003] The first positioning method mentioned above uses a collision barrier and straightens the vehicle to locate the first collision point. It requires a lot of time and manpower during the test preparation process and is inefficient. The second positioning method has low positioning accuracy and there is a risk of test failure. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing method for locating the first collision point of a vehicle, the purpose of the present invention is to provide a positioning device for the first collision point of a vehicle, which can locate the first collision point conveniently and quickly with high positioning efficiency and accuracy.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a positioning device for the first collision point of a vehicle, including a base, a vertical pole and a bracket assembly, the lower end of the vertical pole is connected to the base, the upper end face of the vertical pole is provided with an angle dial, one end of the bracket assembly is rotatably connected to the vertical pole, and the bracket assembly can rotate around the vertical pole, the bracket assembly is provided with an angle pointer, the angle pointer is located above the angle dial, and the bracket assembly is also provided with a canvas body, which is vertically arranged.

[0006] Furthermore, the base includes a first rod and a second rod perpendicular to the first rod, one end of the second rod is connected to the middle of the first rod, and the other end of the second rod is connected to the lower end of the vertical rod. The two ends of the first rod are respectively rotatably connected to a first positioning wheel, and the second rod is provided with a slider that can slide along the second rod, and the lower end of the slider is rotatably connected to a second positioning wheel. The base also includes elastic members respectively connected to the slider and the second rod.

[0007] Furthermore, the elastic member is a tension spring.

[0008] Furthermore, there are two tension springs, which are arranged on both sides of the second rod opposite to each other; one end of the tension spring is connected to the second rod, and the other end of the tension spring is connected to the slider.

[0009] Furthermore, the second rod is rotatably connected to the vertical rod.

[0010] Furthermore, a first steel sleeve is provided at one end of the second rod away from the first rod, a second steel sleeve is provided at the lower end of the vertical rod, and the first steel sleeve and the second steel sleeve are rotatably connected via a pin shaft.

[0011] Furthermore, the bracket assembly includes a third rod and a fourth rod arranged parallel to the third rod, the third rod and the fourth rod are respectively rotatably connected to the vertical rod, a fifth rod is provided at one end of the third rod away from the vertical rod, the fifth rod is hinged to the third rod, a sixth rod is provided at one end of the fourth rod away from the vertical rod, the sixth rod is hinged to the fourth rod, and the canvas body is connected between the fifth rod and the sixth rod.

[0013] Furthermore, the fourth rod is located above the third rod, and the angle pointer is connected to the fourth rod.

[0014] Furthermore, the vertical pole is a multi-section telescopic pole.

[0015] The above technical solution provides a positioning device for the first collision point of a vehicle. Compared with the existing technology, its beneficial effect is that the first collision point when the vehicle collides can be known by touching the canvas body to the vehicle. By rotating the bracket assembly relative to the vertical pole, the canvas body can touch the vehicle at different angles, simulating the vehicle colliding with the barrier from different angles, and measuring the corresponding first collision point. The inclination angle of the canvas body can be directly observed and controlled by cooperating with the angle dial and the angle pointer. Therefore, the first collision point can be accurately positioned at the vehicle starting position using the above positioning device, without moving the test vehicle to the front of the collision barrier.

[0022] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0023] like Figures 1 to 3As shown, an embodiment of the present invention provides a positioning device for the first collision point of a vehicle, including a base 1, a vertical pole 2 and a bracket assembly 3. The lower end of the vertical pole 2 is connected to the base 1, and the upper end face of the vertical pole 2 is provided with an angle dial 4. One end of the bracket assembly 3 is rotatably connected to the vertical pole 2, and the bracket assembly 3 can rotate around the vertical pole 2. An angle pointer 5 is provided on the bracket assembly 3, and the angle pointer 5 is located above the angle dial 4. The angle pointer 5 rotates with the bracket assembly 3, and the angle dial 4 is fixed. A canvas body 6 is also provided on the bracket assembly 3, and the canvas body 6 is vertically arranged.

[0024] Based on the above scheme, the first collision point when the vehicle collides can be known by touching the canvas body 6 to the vehicle. By rotating the bracket assembly 3 relative to the vertical pole 2, the canvas body 6 can touch the vehicle at different angles, simulating the vehicle colliding with the barrier from different angles, and measuring the corresponding first collision point. The inclination angle of the canvas body 6 can be directly observed and controlled by cooperating with the angle dial 4 and the angle pointer 5. Therefore, the first collision point can be accurately positioned at the vehicle starting position using the above positioning device, without moving the test vehicle to the front of the collision barrier. It is convenient and fast, saves time and manpower, and has high measurement efficiency.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the base 1 includes a first rod 11 and a second rod 12 perpendicular to the first rod 11, one end of the second rod 12 is connected to the middle of the first rod 11, and the other end of the second rod 12 is connected to the lower end of the vertical rod 2. The two ends of the first rod 11 are respectively rotatably connected to a first positioning wheel 13, and the second rod 12 is provided with a slider 14 that can slide along the second rod 12. The lower end of the slider 14 is rotatably connected to a second positioning wheel 15. The base 1 also includes an elastic member 16 respectively connected to the slider 14 and the second rod 12.

[0026] Specifically, the first rod 11 and the second rod 12 form a T-shaped structure, and the two first positioning wheels 13 and the second positioning wheel 15 are in a triangle. During testing, the base 1 can be placed on the track 10 of the towing vehicle, the two first positioning wheels 13 are located on the track 10 on one side, and the second positioning wheel 15 is located on the track 10 on the other side. The three positioning wheels can roll along the side of the track 10 respectively, so that the base 1 can move along the track 10, and then during the test, the canvas body 6 is moved close to the vehicle by moving the base 1 until the canvas body 6 contacts the vehicle to determine the first collision point, and the test is simple and quick.

[0027] Among them, the elastic member 16 is used to give the slider 14 a pulling force away from the first rod 11, so that the second positioning wheel 15 is pressed against the track 10 on one side and the first positioning wheel 13 is pressed against the track 10 on the other side. In this way, the two first positioning wheels 13 and the second positioning wheels 15 are stably stuck between the two tracks 10.

[0028] In this embodiment, if Figure 2 As shown, the elastic member 16 is a tension spring. Specifically, there are two tension springs, which are arranged on both sides of the second rod 12; one end of the tension spring is connected to the second rod 12, and the other end of the tension spring is connected to the slider 14; the end of the tension spring can be fixedly connected to the second rod 12 or the slider 14 by welding through a connecting rod.

[0029] Furthermore, in order to facilitate storage, in this embodiment, the second rod 12 is rotatably connected to the vertical rod 2.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, a first steel sleeve 7 is provided at the end of the second rod 12 away from the first rod 11, and a second steel sleeve 8 is provided at the lower end of the vertical rod 2. The first steel sleeve 7 and the second steel sleeve 8 are rotatably connected by a pin shaft 9. When not in use, the vertical rod 2 can be rotated downward and stored.

[0031] In this embodiment, if Figure 3 As shown, the bracket assembly 3 includes a third rod 31 and a fourth rod 32 arranged parallel to the third rod 31. The third rod 31 and the fourth rod 32 are respectively rotatably connected to the vertical rod 2. A fifth rod 33 is provided at the end of the third rod 31 away from the vertical rod 2. The fifth rod 33 is hinged to the third rod 31. A sixth rod 34 is provided at the end of the fourth rod 32 away from the vertical rod 2. The sixth rod 34 is hinged to the fourth rod 32. The canvas body 6 is connected between the fifth rod 33 and the sixth rod 34. When not in use, the fifth rod 33 and the sixth rod 34 can be flipped and folded together with the third rod 31 and the fourth rod 32 respectively through the hinge connection.

[0032] In this embodiment, if Figure 3 As shown, the bracket assembly 3 further includes a first cross bar 35 and a second cross bar 36. The first cross bar 35 and the second cross bar 36 are arranged crosswise and hingedly connected to each other. One end of the first cross bar 35 is rotatably connected to the third bar 31, and the other end of the first cross bar 35 is slidably connected to the fourth bar 32. One end of the second cross bar 36 is rotatably connected to the fourth bar 32, and the other end of the second cross bar 36 is slidably connected to the third bar 31. The third bar 31 is capable of sliding along the vertical rod 2. Through the movement of the two cross bars, the third bar 31 and the fourth bar 32 can be closed and stored. The third bar 31 slides upward to approach the fourth bar 32, further reducing the size of the bracket assembly 3 for easy storage and transportation.

[0033] Among them, such as Figure 3 As shown, the fourth rod 32 is located above the third rod 31, and the angle pointer 5 is connected to the fourth rod 32. When the bracket assembly 3 rotates, the angle pointer 5 is driven to rotate above the angle dial 4, so that the rotation angle of the canvas body 6 can be intuitively observed.

[0034] Furthermore, the vertical pole 2 of this embodiment is a multi-section telescopic pole, for example, a two-stage or three-stage telescopic pole, which is convenient for storage.

[0035] In summary, the embodiments of the present invention provide a device for locating the first collision point of a vehicle, which has the following beneficial effects:

[0036] 1. The positioning device of this embodiment can be used to directly locate the first collision point at the vehicle departure position without moving the test vehicle to the front of the collision barrier, saving time and manpower and increasing efficiency.

[0037] 2. By rotating the bracket assembly 3 and observing the angle pointer 5 and the angle dial 4, it can be applied to the measurement of the first collision point of barriers at different angles, and has wide applicability.

[0038] 3. Through the telescopic and folding structure of each part, it can be stored into a smaller volume, which is more convenient and saves space.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
