[0002] The outlook and trends for new energy vehicles are very optimistic, and they are expected to become the dominant mode of transportation within the next few decades. The development of the new energy vehicle industry is driven by technological advancements, strengthened environmental policies, and growing consumer demand for environmentally friendly and efficient energy. From a long-term perspective, new energy vehicles are expected to become the dominant mode of transportation within the next few decades. As battery manufacturing costs decrease and performance improves, the economic benefits of electric vehicles will become increasingly prominent.

[0003] For new energy vehicles, the battery pack is usually arranged at the chassis position to lower the center of gravity of the vehicle, improve stability and endurance, but it brings the risk of chassis collision. Considering the safety of the vehicle, it is necessary to perform collision detection on the chassis of the new energy vehicle. The detection device is used to test whether the impact strength of the chassis of the new energy vehicle is sufficient. At the same time, it is necessary to observe whether the chassis of the new energy vehicle will be deformed during the collision. At the same time, in the collision test, when the speed of the new energy vehicle is low, the chassis of the vehicle is easy to stay on the collision object due to insufficient inertia after the collision, causing the chassis of the vehicle to be lifted up and stuck by the collision object, and the subsequent moving and debugging of the vehicle is more troublesome. At the same time, when a collision occurs, some collision debris on the chassis of the vehicle will splash, and these debris will fall into the gap of the detection device. Long-term accumulation will affect the detection equipment. These debris are inside the detection equipment, and subsequent manual cleaning is very difficult. Therefore, the present application proposes a vehicle chassis collision force detection device. Summary of the Invention

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figure 1 As shown, the utility model proposes a vehicle chassis collision force detection device, a base 1, a rectangular groove is provided on the base 1, one end of the rectangular groove is installed with a force sensor 7 for testing the collision force, the model of the force sensor 7 is a 600KN-column structure standard dynamometer, the force sensor 7 is used to detect the pressure during the collision, one end of the force sensor 7 contacts a liftable fixed block 6, the fixed block 6 is provided with a plurality of limit columns 601 for fixing the collision block 602, the collision blocks 602 are all used to test the collision with the vehicle chassis, a fan 9 for cleaning debris is installed below the force sensor 7 in the base 1, an arc groove 101 for changing the wind direction of the fan is provided in the base 1, and a slope 103 for assisting in cleaning debris is provided in the base, and the fan 9 can clean the debris inside the base 1 by the action of the arc groove 101 and the slope.

[0023] like Figure 1 As shown, a set of limiting horizontal plates 2 are fixedly connected inside the base 1, and sliding blocks 3 are movably passed through the two limiting horizontal plates 2. Hydraulic telescopic cylinders 4 are fixedly connected to the two sliding blocks 3, and the hydraulic telescopic cylinders 4 are used to lift the collision block 602.

[0024] like Figure 1 and Figure 2 As shown, the top ends of the two hydraulic telescopic cylinders 4 are fixedly connected to the support block 5. A rectangular hole is provided on the support block 5 for socketing the fixed block 6, so that the support block 5 is used to connect the fixed block 6, so that when the collision block 602 is hit, it will drive the support block 5 and the fixed block 6 to be squeezed toward the force sensor 7 at the same time.

[0025] like Figure 4As shown, a plurality of limiting posts 601 are installed on the fixed block 6, and the intervals between the limiting posts 601 are the same size. The plurality of limiting posts 601 are sleeved on the circular holes at the bottom of the collision block 602. The limiting posts 601 are used to fix the collision block 602. At the same time, different collision blocks 602 can be replaced so that the contact area with the car chassis is different during the collision, thereby detecting whether there is a relationship between the impact force and the size of the impacting object.

[0026] like Figure 1 and Figure 2 As shown, a groove is provided on the base 1, and a support frame 8 is fixedly installed in the groove. The support frame 8 is rotatably connected to the display 801, and the display 801 is electrically connected to the force sensor 7. The base 1 is provided with four square grooves, and a hanging ring 102 is installed at the bottom of the square groove. The display 801 is used to display and record the impact force of each car chassis hitting the collision block 602. The hanging ring 102 is used to facilitate the installation of the base 1. At the same time, after the use of the hanging ring 102, a cover for sealing the hanging ring can be placed on the hanging ring 102.

[0027] like Figure 1 and Figure 3 As shown, a rectangular groove is provided on the base 1, and a high-speed camera 10 is installed at the bottom of the rectangular groove. A transparent plate 11 is installed on the base 1 above the high-speed camera 10. The high-speed camera 10 is installed on the inclined surface of the rectangular groove so that the high-speed camera 10 is aligned with the position where the collision block 602 contacts the car chassis, so that the collision image can be recorded during the collision, so as to check whether the chassis is deformed during the collision. At the same time, the transparent plate 11 can play a protective role to prevent some metal debris from damaging the high-speed camera 10 during the collision.

[0028] In this embodiment, first, a base for installing the base 1 is dug out in an open position, and then the base 1 is installed on the base with the help of the lifting ring 102 so that the base 1 is horizontal with the ground, and then the collision block 602 is installed on the limiting column 601, and then the impact angle of the car is adjusted so that the car accelerates to a specified speed and hits the collision block 602. At the moment of impact, the collision block 602 hit by the car will drive the fixed block 6, the support block 5, the hydraulic telescopic cylinder 4 and the sliding block 3 to move to one side, thereby squeezing the force sensor 7, and the elastic element of the force sensor 7 will undergo corresponding deformation. This deformation is then converted into an electrical signal and output to the display 801. According to the value on the display 801, the impact force of the car is judged, and then the high-speed camera 10 is used to check whether the impact is not caused. The deformation of the car bottom plate under the same impact force, when the car collides with the collision block 602 at a low speed, the chassis of the car is easily lifted up by the collision block 602, causing the car to be stuck. At this time, by contracting the hydraulic telescopic cylinder 4, the support block 5, the fixed block 6 and the collision block 602 are driven to descend, so that the chassis of the car is separated from the collision block 602, thereby preventing the car chassis from being stuck by the collision block during the test. At the same time, the debris of the impact will fall into multiple grooves in the base 1 during the splashing process, and thus accumulate on the inclined plate in the base 1. At this time, by starting the fan 9, the air outlet of the fan 9 is aligned with the arc groove 101, so that the high-speed wind blown out by the fan 9 blows onto the arc groove 101, thereby changing the wind direction and expanding the range of the wind, so that the wind blows onto the debris on the inclined plate, thereby blowing the debris onto the collection plate 12.

[0029] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
