Description

Technical Field

[0001] The present invention relates to the technical field of battery guard plates, in particular to a battery guard plate for a new energy vehicle. Background Art

[0002] With the rapid development of new energy vehicles, the safety and reliability of power batteries, as core components, have drawn significant attention. Battery packs are typically mounted on the underside of the vehicle chassis, making them susceptible to environmental impacts such as road debris, corrosion from accumulated water, and impacts. These can lead to damage, leakage, and even thermal runaway. Therefore, the protective performance of the battery shield is directly related to vehicle safety and battery life.

[0003] Traditional battery shields are mostly designed with a single material structure (such as aluminum alloy or steel plate). Although they have certain strength and impact resistance, they still have the following defects: a. There is a contradiction between lightweight and protective performance. The aluminum alloy guard plate is light in weight but lacks rigidity. When the obstacle is high or hard, the aluminum alloy guard plate is prone to deformation and failure under severe impact. The deformed aluminum alloy guard plate may also cause damage to the battery.

[0004] b. It is inconvenient to repair. When the integrated guard plate is damaged, it needs to be replaced as a whole, which results in high maintenance costs.

[0005] Therefore, the present application provides a new energy vehicle battery guard plate to solve the problems of poor protection effect and high maintenance cost of battery guard plates in the prior art. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a new energy vehicle battery guard plate.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a new energy vehicle battery guard plate, comprising a detection portion, a guide portion and a plurality of guard plate portions arranged in sequence from front to rear, the detection portion comprising a vertically swingable detection plate, when the detection plate rotates backward, the guard plate portion is released downward to form a plurality of reinforced protection portions; The guard plate part includes a release part and two guard plates rotatably connected to the bottom of the battery. The outer ends of the guard plates are overlapped and arranged on the lower side of the release part. One of the guard plates is provided with a limiting component, and the other guard plate is provided with a guide groove. When the release part is released, the airflow generated pushes the two guard plates to rotate downward, and the limiting component moves to the bottom of the guide groove and locks.

[0008] As an optimization, several of the guard plate parts are arranged in an array along the width direction of the battery, the length of the guard plate part is not less than the length of the battery, and the reinforced protective part is a V-shaped support structure with an opening facing upward.

[0009] As an optimization, the release part includes a protective barrier layer connected to the bottom of the battery, an explosive layer and a protective film. The bottom of the protective barrier layer forms a filling groove, the explosive layer is evenly laid in the filling groove, and the protective film covers the bottom of the filling groove to limit the explosive layer. The release portion further comprises a trigger assembly, which is used to ignite the explosive layer.

[0010] As an optimization, the upper end of the protective plate is rotatably connected to the bottom of the battery, the upper portion of the protective plate is inclined in a direction away from the release portion, and the lower portion of the protective plate is bent toward the lower side of the release portion, and the lower portions of the two protective plates are staggered and arranged on the lower side of the release portion; The two protective plates are respectively a first protective plate and a second protective plate. The limiting assembly is fixed to the bottom of the first protective plate. The guide groove is provided on the second protective plate. The limiting assembly is provided through the guide groove.

[0011] As an optimization, the guide assembly includes a guide rod, and a limiting end piece is provided at the lower end of the guide rod. After the guide rod passes through the guide groove, the limiting end piece is provided on the lower side of the guide groove.

[0012] As an optimization, the two long sides of the guide groove are provided with limiting ratchets, and the limiting ratchets on the two long sides are staggered; The guide rod is in the shape of a triangular prism, and one of the side edges of the guide rod is arranged toward the outer end of the guide groove. When the guide rod moves outward along the guide groove, the movement trajectory of the guide rod is W-shaped. When the guide rod moves to the outer end of the guide groove, the limiting ratchet can limit the guide rod.

[0013] As an optimization, the bottom of the detection part is higher than the guard plate part, the detection part includes a detection plate, and the detection plate is rotatably connected to the car floor. The guide part includes a guide plate, and the lower end of the guide plate is not higher than the bottom of the battery, and the lower end of the guide plate is inclined toward the bottom of the battery.

[0014] As an optimization, a damping shaft is connected between the detection plate and the vehicle floor, and the damping shaft is equipped with an angle sensor.

[0015] This solution provides a new energy vehicle battery guard plate with the following benefits: The present application sets a guard plate portion on the lower side of the new energy battery. In the event of a large impact, the guard plate is pushed downward by the release portion, so that the two guard plates are arranged opposite to each other to form a reinforced guard portion. The reinforced guard portion forms a triangular structure with the battery, effectively enhancing the protective effect of the guard plate portion. In addition, the guard portion can push obstacles during the downward impact to prevent movable obstacles from bouncing upward and hitting the battery. If the impact force is large, the vehicle can also be forced to float upward to prevent obstacles from impacting the battery. The detection part detects obstacles, and the guide part guides movable obstacles to ensure the efficient release and use of the guard plate part. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-9 As shown, a new energy vehicle battery guard plate includes a detection portion, a guide portion, and a plurality of guard plate portions arranged in sequence from front to back. The detection portion includes a detection plate 1 that is vertically swingable. When the detection plate 1 rotates backward, the guard plate portion is released downward to form a plurality of reinforced protective portions. The guard plate part includes a release part and two guard plates rotatably connected to the bottom of the battery. The outer ends of the guard plates are overlapped and arranged on the lower side of the release part. One of the guard plates is provided with a limiting component, and the other guard plate is provided with a guide groove 4. When the release part is released, the airflow generated pushes the two guard plates to rotate downward, and the limiting component moves to the bottom of the guide groove 4 and is locked.

[0028] This solution also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical devices used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, AMD processor, PLC controller, ARM processor or single-chip microcomputer, and is also used with a motherboard, memory stick, storage medium and power supply, and the power supply is AC or lithium battery; when a display screen is provided, a display card is also provided.

[0029] Multiple pressure sensors can be installed at the bottom of the detection plate 1, evenly distributed along the length of the detection plate 1, to detect the collision position between the obstacle and the vehicle chassis. Correspondingly, multiple pressure sensors can also be installed at the bottom of the guide portion. Based on the collision position between the obstacle and the bottom of the detection plate 1 and the collision position between the obstacle and the bottom of the guide plate 11, the collision position between the obstacle and the bottom of the battery can be calculated. If the contact trajectory between the obstacle and the bottom of the vehicle is linear, the guard plate portion behind the trajectory can be opened accordingly. If the contact trajectory between the obstacle and the vehicle cannot be accurately predicted, all guard plates can be opened downward.

[0030] 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 surface obstacle is heavy and the impact force with the vehicle is strong, it is necessary to release the guard plate part to protect the battery.

[0031] Several guard plate parts are arranged in an array along the width direction of the battery, the length of the guard plate part is not less than the length of the battery, and the reinforced protection part is a V-shaped support structure with an opening facing upward.

[0032] like Figure 6 As shown, the release part includes a protective barrier 5 connected to the bottom of the battery, an explosive layer 6 and a protective film 7. The bottom of the protective barrier 5 forms a filling groove, and the explosive layer 6 is evenly laid in the filling groove. The protective film 7 covers the bottom of the filling groove to limit the explosive layer 6. The release portion further comprises a trigger assembly, which is used to ignite the explosive layer 6 .

[0033] The protective barrier 5 should be an insulating layer with a certain hardness, which can protect against the impact of the explosive layer 6. At the same time, the protective film 7 is a paper film or plastic soft film that is easy to break through downward. When the explosive layer 6 explodes, the shock wave generated can quickly impact downward, break through the protective film 7, and push the guard plate part downward.

[0034] The trigger component can be a module such as an electronic ignition component that can release current to the explosive layer 6. The explosive layer 6 contains small-equivalent explosives, and the specific filling amount is preferably such that the protective plate can be pushed downward.

[0035] like Figure 6 As shown, the upper end of the protective plate is rotatably connected to the bottom of the battery, the upper portion of the protective plate is inclined in a direction away from the release portion, and the lower portion of the protective plate is bent toward the lower side of the release portion, and the lower portions of the two protective plates are staggered and arranged on the lower side of the release portion; The two protective plates are respectively a first protective plate 2 and a second protective plate 3 , the limiting assembly is fixed to the bottom of the first protective plate 2 , the guide groove 4 is provided on the second protective plate 3 , and the limiting assembly is provided through the guide groove 4 .

[0036] The first and second protective plates 2 and 3 overlap, with the overlap being no less than half the width of the release portion. This overlap protects and supports the release portion. When the protective plates are extended outward, they and the release portion form a triangular support structure at the bottom of the battery.

[0037] like Figure 6 As shown, the guide assembly includes a guide rod 8, and a limiting end piece 9 is provided at the lower end of the guide rod 8. After the guide rod 8 passes through the guide groove 4, the limiting end piece 9 is provided on the lower side of the guide groove 4.

[0038] The guide groove 4 can limit the guide rod 8 , and the guide rod 8 can also move along the guide groove 4 .

[0039] like Figure 6 As shown, the two long sides of the guide groove 4 are provided with limiting ratchets 10, and the limiting ratchets 10 on the two long sides are staggered; The guide rod 8 is in the shape of a triangular prism, and one of the side edges of the guide rod 8 is set toward the outer end of the guide groove 4. When the guide rod 8 moves outward along the guide groove 4, the movement trajectory of the guide rod 8 is W-shaped. When the guide rod 8 moves to the outer end of the guide groove 4, the limiting ratchet 10 can limit the guide rod 8.

[0040] The tooth tip of the limiting ratchet 10 faces the outer end of the guide groove 4, so that the guide rod 8 can move outward along the guide groove 4. When the guide rod 8 reaches the outer end of the guide groove 4, the limiting ratchet 10 can limit the guide rod 8.

[0041] like Figure 1 and Figure 2 As shown, the bottom of the detection part is higher than the guard plate part, the detection part includes a detection plate 1, and the detection plate 1 is rotatably connected to the car floor. The guide part includes a guide plate 11, and 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 inclined toward the bottom of the battery.

[0042] When the guard plate part is retracted upward, the bottom of the guard plate part is higher than the bottom of the guide part.

[0043] like Figure 1 As shown, a damping shaft is connected between the detection plate 1 and the vehicle floor, and the damping shaft is equipped with an angle sensor.

[0044] The angle sensor can be used to detect the rotation angle of the detection plate 1. A certain angle is preset through the controller. When the angle sensor detects that the rotation angle of the detection plate 1 exceeds the set threshold, the guard plate part is released.

[0045] Directions: When the device is in use, the detection plate 1 detects obstacles on the road during the vehicle's movement. If a large obstacle impacts the detection plate 1, the guard plate portion is released downward. When the car passes an obstacle, if the obstacle is hard, the obstacle will impact the detection plate 1, causing the detection plate 1 to rotate relative to the bottom of the car. The angle sensor detects the rotation angle of the detection plate 1. When the rotation angle of the detection plate 1 exceeds the set angle threshold, the controller controls the guard plate to release downward. The controller controls the operation of the trigger assembly, which ignites the explosive layer 6. After the explosive layer 6 explodes, an air flow impact is generated. After the air flow breaks through the protective film 7, it pushes the two protective plates downward to rotate; 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 stop rotating downward. The guide rod 8 is limited by the limiting ratchet 10, so that the protective plates cannot be reset upward. The first protective plate 2 and the second protective plate 3 form a triangular prism-shaped reinforced protective portion on the lower side of the battery. The reinforced protective portion is arranged in contact with the bottom of the battery, with the tip facing downward and evenly distributed on the bottom of the battery. After the obstacle passes through the detection plate 1, it is guided by the guide plate 11 and enters the lower side of the tram. By strengthening the contact between the protective part and the obstacle, the obstacle can be broken, or the support between the protective part and the obstacle can be strengthened to make the vehicle float upward, avoiding the impact between the obstacle and the battery, and being able to evenly distribute the impact force to avoid excessive local impact force.
