In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] As shown in Figures 1-9 A new energy automobile battery guard plate, comprising a detection part, a guide part and a plurality of guard plate parts arranged in sequence from front to back, the detection part comprises a vertically swingable detection plate 1, when the detection plate 1 rotates backward, the guard plate part releases downward to form a plurality of reinforced protection parts;

[0035] The guard plate part comprises a release part and two protection plates rotatably connected with the bottom of the battery, the outer ends of the protection plates are overlapped and arranged on the lower side of the release part, one of the protection plates is provided with a limiting assembly, and the other protection plate is provided with a guide groove 4. When the release part releases, the airflow generated pushes the two protection plates downward to rotate, and the limiting assembly moves to the bottom of the guide groove 4 and is locked.

[0036] The scheme also includes a controller, the position of the controller is set by the worker according to the actual situation when working, the controller is used to control the electrical devices used in the scheme, including but not limited to sensors, motors, telescopic rods, water pumps, electromagnetic valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lamps, speakers and microphones; the controller is an Intel processor, an AMD processor, a PLC controller, an ARM processor or a single-chip microcomputer, and is used with a mainboard, a memory bar, a storage medium and a power supply, the power supply is a mains electricity or a lithium battery; when the display screen is provided, a display card is also provided.

[0037] A plurality of pressure sensors can be arranged on the bottom of the detection plate 1 and uniformly distributed along the length direction of the detection plate 1, to detect the collision position of the obstacle and the vehicle chassis. Correspondingly, a plurality of pressure sensors can also be arranged on the bottom of the guide part, and the collision position of the obstacle and the bottom of the battery can be calculated according to the collision position of the obstacle and the bottom of the detection plate 1 and the collision position of the obstacle and the bottom of the guide plate 11. When the contact trajectory of the obstacle and the vehicle bottom is linear, the guard plate parts behind the trajectory can be opened correspondingly, and if the contact trajectory of the obstacle and the vehicle cannot be accurately predicted, all the guard plate parts can be opened downward.

[0038] There is a certain rotational resistance between the detection plate 1 and the vehicle chassis. When the obstacle can overcome the rotational resistance and make the detection plate 1 rotate, if the obstacle on the surface is heavy and the impact force with the vehicle is strong, then the protective plate needs to be released to protect the battery.

[0039] Several of the aforementioned protective plate portions are arranged in an array along the width direction of the battery, the length of each protective plate portion is not less than the length of the battery, and the reinforced protective part is a V-shaped support structure with the opening facing upward.

[0040] like Figure 6 As shown, the release part includes a protective partition 5, an explosive layer 6, and a protective film 7 connected to the bottom of the battery. The bottom of the protective partition 5 forms a filling groove. The explosive layer 6 is evenly laid in the filling groove. The protective film 7 covers the bottom of the filling groove and limits the explosive layer 6.

[0041] The release section also includes a triggering component for igniting the explosive layer 6.

[0042] The protective layer 5 should be a heat insulation layer with a certain degree of hardness to protect against the impact of the explosive layer 6. Meanwhile, the protective film 7 should be a paper film or plastic soft film that is easy to penetrate downwards. When the explosive layer 6 explodes, the resulting shock wave can quickly impact downwards, penetrate the protective film 7, and push the protective plate part downwards.

[0043] The triggering component can be an electronic ignition component or other module that can release current to the explosive layer 6. The explosive layer 6 contains a small amount of explosive, and the specific filling amount should be such that the protective plate can be pushed down.

[0044] like Figure 6 As shown, the upper end of the protective plate is rotatably connected to the bottom of the battery. The upper part of the protective plate is inclined away from the release part, and the lower part of the protective plate is bent towards the lower side of the release part. The lower parts of the two protective plates are staggered and arranged on the lower side of the release part.

[0045] The two protective plates are a first protective plate 2 and a second protective plate 3. The limiting component is fixed to the bottom of the first protective plate 2, and the guide groove 4 is disposed on the second protective plate 3. The limiting component passes through the guide groove 4.

[0046] The first protective plate 2 and the second protective plate 3 are overlapped, with the overlap portion being no less than half the width of the release portion. The overlap portion can protect and support the release portion. After the protective plates are released outward, the protective plates and the release portion form a triangular support structure at the bottom of the battery.

[0047] like Figure 6As shown, the guide assembly comprises a guide rod 8, the lower end of the guide rod 8 is provided with a limiting end piece 9, after the guide rod 8 passes through the guide groove 4, the limiting end piece 9 is arranged on the lower side of the guide groove 4.

[0048] The guide groove 4 can limit the guide rod 8, and the guide rod 8 can also move along the guide groove 4.

[0049] As shown in the drawings, Figure 6 As shown, the two long edges of the guide groove 4 are provided with limiting ratchets 10, and the limiting ratchets 10 of the two long edges are staggered;

[0050] The guide rod 8 is a triangular prism, one side of the guide rod 8 is arranged towards the outer end of the guide groove 4, and the moving track of the guide rod 8 is W-shaped when the guide rod 8 moves outward along the guide groove 4, and the limiting ratchet 10 can limit the guide rod 8 when the guide rod 8 moves to the outer end of the guide groove 4.

[0051] The tooth tip of the limiting ratchet 10 is towards the outer end of the guide groove 4, so that the guide rod 8 can move outward along the guide groove 4, and the limiting ratchet 10 can limit the guide rod 8 when the guide rod 8 reaches the outer end of the guide groove 4.

[0052] As shown in the drawings, Figure 1 And Figure 2 As shown, the bottom of the detection part is higher than the bottom of the guard part, the detection part comprises a detection plate 1, the detection plate 1 is rotatably connected with the automobile bottom plate, the guide part comprises a guide plate 11, the lower end of the guide plate 11 is not higher than the bottom of the battery, and the lower end of the guide plate 11 is arranged obliquely towards the bottom of the battery.

[0053] When the guard part is folded up, the bottom of the guard part is higher than the bottom of the guide part.

[0054] As shown in the drawings, Figure 1 As shown, a damping shaft is connected between the detection plate 1 and the automobile bottom plate, and the damping shaft is provided with an angle sensor.

[0055] The angle sensor can be used to detect the rotation angle of the detection plate 1, and a certain angle is set by the controller, and when the angle sensor detects that the rotation angle of the detection plate 1 exceeds the set threshold, the guard part is released.

[0056] Method for use:

[0057] When the device is used, the detection plate 1 detects the obstacles on the road surface during the driving of the automobile, and when a larger obstacle impacts the detection plate 1, the guard part is released downward;

[0058] When the automobile passes through the obstacle, such as the obstacle is hard, the obstacle will impact the detection plate 1, so that the detection plate 1 and the bottom surface of the automobile are relatively rotated, the rotation angle of the detection plate 1 is detected through the angle sensor, when the rotation angle of the detection plate 1 exceeds the set angle threshold, the controller controls the release of the baffle part downward;

[0059] The controller controls the trigger assembly to operate, through the operation of the trigger assembly, the explosive layer 6 is ignited, and after the explosion of the explosive layer 6, the airflow impact is generated, the airflow breaks through the protective film 7 and pushes the two protective plates downward to rotate downward;

[0060] When the first protective plate 2 and the second protective plate 3 rotate downward, the guide rod 8 moves downward along the guide groove 4, until the two protective plates no longer rotate downward, the guide rod 8 is limited by the limiting ratchet 10, so that the protective plate cannot be reset upward;

[0061] The first protective plate 2 and the second protective plate 3 form a three-prism-shaped reinforced protection part on the lower side of the battery, and the reinforced protection part is arranged in close contact with the bottom of the battery, the sharp end is downward, and is uniformly distributed on the bottom of the battery;

[0062] After the obstacle passes through the detection plate 1, it is guided through the guide plate 11 and enters the lower side of the electric vehicle, and the reinforced protection part contacts the obstacle, so that the obstacle is broken, or the reinforced protection part supports the obstacle, so that the vehicle floats upward, avoids the impact of the obstacle on the battery, and can uniformly distribute the impact force and avoid local impact force being too large.

[0063] The above specific embodiments are only specific cases of the application, the patent protection scope of the application includes but is not limited to the product forms and styles of the above specific embodiments, any appropriate changes or modifications made by any ordinary skilled person in the corresponding technical field to the new energy automobile battery baffle according to the claims of the application shall fall within the patent protection scope of the application.
