Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a ground contact buffer device and an electric vehicle. Background Technology

[0002] Vehicles are an important means of transportation for people, and therefore there are a great many of them. Consequently, there are also many safety accidents. To ensure the personal safety of drivers and passengers, vehicles are equipped with safety components such as seat belts and airbags. However, in cases of high vehicle speed and violent collisions, serious personal injuries can still occur. Therefore, it is necessary to further enhance the safety performance of vehicles.

[0003] The existing utility model patent with authorization announcement number CN2035800853U discloses a vehicle anti-collision ground contact shock absorption device, belonging to the field of vehicle mechanics. It mainly consists of a shock absorber rod, a spring, a force-bearing bar, and a slide groove. The shock absorber rod is inclined to the ground and is made of metal. One end of the shock absorber rod passes through the hole of the spring and is connected and fixed to the force-bearing bar. The force-bearing bar is installed at the front or rear of the vehicle and is connected to the spring. A slide groove is installed around the shock absorber rod, and the outer wall of the slide groove is fixed to the vehicle body. One end of the spring is connected to the outer wall of the slide groove.

[0004] The above-mentioned technical solution connects the shock absorber rod directly to the load-bearing bar. However, due to the unstable and unpredictable deformation of the load-bearing bar during a vehicle accident, it cannot be guaranteed that the shock absorber rod can achieve a good shock absorption effect. Therefore, it is urgent to improve it. Utility Model Content

[0023] like Figure 1 and Figure 2 As shown, the ground contact buffer device of this utility model includes a base 1, a driving component 2, a support 21, a sleeve 22, a piston rod 23, a contact component 3, a collision sensor 4, and a controller 5. The electric vehicle of this utility model includes the aforementioned ground contact buffer device and also includes a safety airbag 6.

[0024] like Figure 1 and Figure 2 As shown, the base 1 is connected to the vehicle body; the drive component 2 is mounted on the base 1; the contact component 3 is movably mounted on the base 1. The drive component 2 is used to drive the contact component 3 to move so as to cushion the impact with the ground after the vehicle is hit. As described above, base 1 serves as the mounting base and is installed on the vehicle; Both the driving component 2 and the contact component 3 are mounted on the base 1, and the contact component 3 is movably connected to the base 1. Thus, after a vehicle collision, the driving component 2 can drive the contact component 3 to move so that the contact component 3 can abut against the ground, thereby achieving a shock absorption and buffering effect. In this design, since the contact element 3 is actively opened and its direction is fixed, the stability of the action can be ensured, thus ensuring a good shock absorption effect. This structure operates quickly and stably, which can improve the safety performance of the vehicle.

[0025] Specifically, base 1 is a crash beam or vehicle chassis.

[0026] like Figure 1 As shown, the contact element 3 has a rod-shaped structure, and one end of the contact element 3 is hinged to the base 1; As described above, the contact 3 is a rod-shaped structure with one end hinged to the base 1. In the illustrated structure, the contact 3 is in the open state. When not triggered, the contact 3 is parallel to the base 1 and in the retracted state. After being impacted, the contact 3 is rotated by the drive 2, thereby opening.

[0027] In some embodiments, the drive element 2 is a cylinder.

[0028] In some embodiments, such as Figure 1 As shown, the driving component 2 includes a support 21, a sleeve 22 and a piston rod 23. The support 21 is connected to the base 1. The sleeve 22 is disposed on the support 21 and a power component is disposed inside the sleeve 22. One end of the piston rod 23 is slidably connected to the sleeve 22 and abuts against the power component, while the other end of the piston rod 23 abuts against the contact component 3. As described above, the support 21 of the driving component 2 is used to connect and fix it to the base 1, and the base 1 is provided with a sleeve 22 and a piston rod 23 connected to the sleeve 22. During operation, the power component inside the sleeve 22 moves to push out the piston rod 23, and then the piston rod 23 can push the contact member 3 to open. Specifically, the power source is an explosive to ensure rapid operation.

[0029] like Figure 2 As shown, the collision sensor 4 is installed on the electric vehicle; the controller 5 is installed on the electric vehicle and is electrically connected to the collision sensor 4 and the drive unit 2. As described above, the collision sensor 4 can be an acceleration sensor to detect whether a collision has occurred and transmit the detection signal to the controller 5. The controller 5 then analyzes, processes, and judges the signal. It performs calculations according to a pre-set algorithm to determine whether the conditions for activating the ground contact buffer device have been met. Specifically, the ground contact buffer device will not activate when the seat sensor does not detect weight in low-speed collisions (less than 16 km / h), side collisions, rear-end collisions, small-angle scraping impacts that do not meet the set directional requirements, when the vehicle's engine shutdown system is not powered, or when there are no passengers in the vehicle. Specifically, when the vehicle starts, the safety system begins a self-check and monitors the data from the collision sensor 4 in real time. When a collision occurs, the controller 5 analyzes the data fed back by the collision sensor 4. If the force of the frontal collision is greater than 20G, the controller 5 activates the ground contact buffer device. In some embodiments, the ground contact buffer device shares the controller 5 with the airbag 6.

[0030] Specific implementation steps: If a frontal collision occurs while the vehicle is in motion and the impact force is sufficient, the controller 5 detonates the explosive in the sleeve 22 to push out the piston rod 23. Then, the piston rod 23 pushes the contact member 3, which in turn holds the ground, thereby achieving a buffering and shock absorption effect.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
