Of course, they are merely examples and are not intended to limit the present invention.

[0034] Vehicle safety is a major concern. With the booming new energy vehicle market, the number of new energy vehicles, led by electric vehicles, has surged year by year. Battery pack protection (such as power battery packs) is closely linked to vehicle safety, and battery pack protection and impact resistance are increasingly receiving attention.
[0035] Taking the power battery pack as an example, the power battery pack is usually installed under the vehicle. During driving, it is easy to scratch, collide or bottom out with objects on the ground, causing damage to the power battery pack, thereby affecting driving safety.
[0036] In the related art, the power battery pack casing is typically thickened to rely on its inherent strength to withstand potential scrapes or collisions. However, even with a thickened power battery pack casing, its strength is often insufficient to withstand the impact of collisions with obstacles such as road humps, deep potholes, and rocks. This can easily cause the internal cells of the power battery pack to be squeezed and deformed, leading to spontaneous combustion of the power battery pack and other issues that affect vehicle driving safety.
[0037] Therefore, currently, protective structures are often installed on the bottom of the vehicle body to prevent scratches and collisions. For example, a protective structure with a certain angle (such as a protective plate) can be fixedly installed under the power battery pack to buffer the pressure on the power battery pack.
[0038] Although this type of protective structure can provide a certain degree of protection for the bottom of the vehicle body, since the area of the protective structure is usually large and the position and inclination angle of the protective structure are usually fixed, it is easy to affect the vehicle's passability during driving, as well as the vehicle's wind resistance performance and safety performance.
[0039] In order to solve the above technical problems, an embodiment of the present application provides a protective device and a vehicle.
[0040] The following first introduces the application scenarios of the technical solution of this application. The protective device 100 provided by this application can be used in Figure 1 In vehicle 1000 shown.
[0041] See also Figure 1 and Figure 2 The vehicle 1000 includes a vehicle body 200 and a battery 300. The battery 300 is disposed at the bottom of the vehicle body 200. The protective device 100 may be disposed on the vehicle body 200 and / or connected to the frame of the vehicle 1000. The protective device 100 includes:
[0042] The protection part 10 has a first state and a second state;
[0043] In the first state, the lower edge of the guard portion 10 in the height direction of the vehicle 1000 is equal to or higher than the upper edge of the protection object. In the second state, the lower edge of the guard portion 10 in the height direction of the vehicle 1000 is lower than the lower edge of the protection object.
[0044] The first state and the second state may include different minimum heights of the protective portion 10 from the ground. For example, in the first state, the lower edge of the protective portion 10 is at a first height above the ground, and in the second state, the lower edge of the protective portion 10 is at a second height, with the first height being greater than the second height above the ground. For another example, assuming the protective portion 10 includes a first end and a second end, and assuming the height of the first end is fixed, the height of the second end can be adjusted up and down. In the first state, the height of the second end is adjusted to be greater than the first end, i.e., the height of the second end in the direction of the height of the vehicle 1000 is greater than the height of the first end in the direction of the height of the vehicle 1000. In this case, the lower edge of the protective portion 10 is the first end, the upper edge is the second end, and the first end is equal to or higher than the upper edge of the protected object. In the second state, the height of the second end is adjusted to be less than the second end, i.e., the height of the second end in the direction of the height of the vehicle 1000 is less than the height of the first end in the direction of the height of the vehicle 1000. In this case, the lower edge of the protective portion 10 is the second end, the upper edge is the first end, and the second end is lower than the lower edge of the protected object.
[0045] The protection part 10 may be a protection plate, a protection net, a protection rod, etc. The protection part 10 may be provided to connect the vehicle body 200 and the frame of the vehicle 1000 ; or, the protection part 10 may be integrally formed with the frame of the vehicle 1000 .
[0046] The protected object may be a device or component located at the bottom of the vehicle 1000, such as the battery 300, the fuel tank of the vehicle 1000, or a brake, which may collide with an obstacle. For ease of explanation, the present embodiment uses the battery 300 located at the bottom of the vehicle 1000 as an example. When the protected object is other devices or components, the implementation principles are similar and will not be further described here.
[0047] The battery 300 can provide power for the operation of the vehicle 1000 (such as driving, etc.).
[0048] Alternatively, the battery 300 may be a power battery 300, such as a lithium-ion battery 300 (Li-ion), a lithium iron phosphate battery 300 (LiFePO4), etc. By placing the battery 300 at the bottom of the vehicle body 200, the weight distribution of the vehicle 1000 can be optimized, the stability of the vehicle 1000 can be improved, and hardware installation space within the vehicle 1000 can be saved.
[0049] Optionally, the protection device 100 includes one or more protection devices 100 , and the protection devices 100 may be disposed on the vehicle body 200 and arranged along the edge toward the center of the vehicle body 200 .
[0050] Optionally, the protection device 100 is provided on the side or bottom of the vehicle body 200 .
[0051] The protective device 100 can be installed on the side of the vehicle body 200 and at the edge of the vehicle body 200. For example, the protective device 100 can be installed at the edge of the rear of the vehicle body 200; and / or the protective device 100 can be installed at the edge of the front of the vehicle body 200; and / or the protective device 100 can be installed at the left and right edges of the vehicle body 200. If multiple protective devices 100 are included, the protective devices 100 are installed around the vehicle body 200 to provide protection for the battery 300 and improve safety.
[0052] For another example, the protection device 100 may be disposed on the bottom surface of the vehicle body 200 . For example, the protection device 100 may be disposed around the battery 300 at the bottom of the vehicle body 200 to provide protection for the battery 300 .
[0053] Optionally, along the width direction of the protective portion 10 , the width of the protective portion 10 is greater than the width of the protected object, the width direction is perpendicular to the length direction, and the length direction is the direction from the upper edge to the lower edge of the protective structure.
[0054] Among them, see Figure 2 The length direction of the protective portion 10 is the direction from the upper edge of the protective portion 10 to the lower edge of the protective portion 10, and the width direction is perpendicular to the length direction. Assuming that the length of the protective portion 10 is L and the width is H, the width H of the protective portion 10 matches the width of the battery 300 (for example, the width of the protective portion 10 is greater than or equal to a certain threshold of the width of the battery 300), so that the protective portion 10 can cover both sides of the battery 300, providing protection for the battery 300 and preventing the battery 300 from being impacted. Because the width of the protective portion 10 can be determined based on the width of the battery 300 to be protected, the area or volume of the protective portion 10 can be avoided from being excessively increased, thus saving costs and ensuring structural stability.
[0055] Optionally, the vehicle 1000 includes an information collection device 201 , which is disposed on the vehicle body 200 .
[0056] For example, the information collection device 201 may be an infrared sensor, a radar sensor, an image sensor, etc. Based on the information collection device 201 , it is possible to determine whether there are obstacles around the vehicle 1000 , the height of the obstacles, the distance between the obstacles and the vehicle 1000 , etc.
[0057] Specifically, the protection device 100 is connected to the frame of the vehicle 1000, and the protection device 100 includes a protection portion 10, for example, see Figure 3The protective device 100 can be set at the rear of the vehicle 1000, the protective part 10 can be a protective plate, the protective plate can move up and down along the height direction of the vehicle 1000, the protective plate includes a first upper edge A and a first lower edge B, the battery 300 includes a second upper edge a and a second lower edge b, in the first state, the protective plate can move upward so that the first lower edge B of the protective plate is equal to or higher than the second upper edge a of the battery 300 to ensure the passability of the vehicle 1000, and in the second state, the protective plate can move downward so that the first lower edge B of the protective part 10 in the height direction of the vehicle 1000 is lower than the second lower edge b of the battery 300 to achieve protection of the battery 300.
[0058] The protective part 10 has a first state and a second state. For example, when there is no risk of collision between the protected object at the bottom of the vehicle 1000 and the obstacle (such as when the height of the obstacle is less than the height of the protected object at the bottom of the vehicle 1000 from the ground), the protective part 10 can be in the first state. At this time, the lower edge of the protective part 10 in the height direction of the vehicle 1000 is equal to or higher than the upper edge of the protected object, that is, the height of the lower edge of the protective part 10 from the ground is greater than the height of the protected object at the bottom of the vehicle 1000 from the ground, reducing the impact on the passability of the vehicle 1000, avoiding scratches on bumps, potholes, etc. on the road surface due to the protective device 100 being too low, ensuring the wind resistance performance of the vehicle 1000, and ensuring the stability and safety of the vehicle 1000. For another example, when there is a risk of collision between the protected object at the bottom of the vehicle 1000 and an obstacle (such as when the height of the obstacle is greater than or equal to the height of the protected object at the bottom of the vehicle 1000 from the ground), the protective part 10 can be in the second state, at which time the lower edge of the protective part 10 in the height direction of the vehicle 1000 is lower than the lower edge of the protected object, that is, the height of the lower edge of the protective part 10 from the ground is less than the height of the protected object at the bottom of the vehicle 1000 from the ground. When the obstacle may collide with the bottom of the vehicle 1000, the protective part 10 can intercept the obstacle to prevent the protected object at the bottom of the body 200 of the vehicle 1000 from being collided and scratched, thereby providing protection for the protected object of the vehicle 1000.
[0059] For example, the protected object is a battery 300, the battery 300 is arranged at the bottom of the vehicle body 200, and the protective device 100 is arranged on the vehicle body 200, and the protective device 100 and the battery 300 are arranged in sequence along the edge of the vehicle body 200 toward the center. When an obstacle is close to the battery 300 under the vehicle, the obstacle will first pass through the protective device 100 and then pass through the battery 300. Therefore, before the obstacle collides with the battery 300, it will first be intercepted by the protective device 100, that is, the protective device 100 can provide protection for the battery 300 in the first time to prevent the battery 300 from being damaged.
[0060] In this way, the protective device 100 is connected to the frame of the vehicle 1000. The protective device 100 includes a protective part 10, and the protective part 10 has a first state and a second state; in the first state, the lower edge of the protective part 10 in the height direction of the vehicle 1000 is equal to or higher than the upper edge of the protected object, reducing the impact on the passability of the vehicle 1000, and avoiding scratches on road bumps, potholes, etc. due to the protective device 100 being too low, ensuring the wind resistance performance of the vehicle 1000, and ensuring the stability and safety of the vehicle 1000 in driving; in the second state, the lower edge of the protective part 10 in the height direction of the vehicle 1000 is lower than the lower edge of the protected object, which can intercept obstacles and avoid collision and scratches on the protected object at the bottom of the body 200 of the vehicle 1000, so as to provide protection for the protected object of the vehicle 1000. The user can adaptively control the first state or the second state of the protective part 10 based on the actual application scenario requirements, and the protective device 100 has better flexibility and adaptability.
[0061] See also Figures 2 to 4 In some embodiments, the protection device 100 further includes a driving unit 20 , which drives the protection unit 10 to switch between the first state and the second state.
[0062] One end of the driving portion 20 is connected to the vehicle frame, and the other end is connected to the lower edge of the protection portion 10 .
[0063] The driving unit 20 includes a telescopic cylinder, a motor, a hydraulic system, and the like.
[0064] Optionally, the driving part 20 includes a cylinder and a telescopic rod, one end of the cylinder of the driving part 20 is connected to the vehicle frame, and the telescopic rod of the driving part 20 is connected to the lower edge of the protective part 10 .
[0065] The cylinder provides the driving force to push the telescopic rod to extend and retract. Since the telescopic rod is connected to the lower edge of the protective portion 10, the extension and retraction of the telescopic rod can drive the lower edge of the protective portion 10 to move (extend and retract). In other words, the driving unit 20 pushes the lower edge of the protective portion 10 to move downward around the upper edge, thereby adjusting the height of the protective portion 10 and switching between the first and second states.
[0066] Optionally, a plurality of driving parts 20 are provided, and the plurality of driving parts 20 are sequentially arranged along the width direction of the protective part 10 , where the width direction is perpendicular to the length direction, and the length direction is the direction from the upper edge to the lower edge of the protective structure.
[0067] Specifically, multiple drive units 20 can be arranged in sequence along the width direction of the protective part 10. The multiple drive units 20 work together to collaboratively drive the protective part 10 to move. In the event that a certain drive unit 20 fails, the multiple drive units 20 can still function to adjust the height of the protective part 10, thereby improving the stability of the system.
[0068] Optionally, the driving part 20 is set as one, and along the width direction of the protective part 10, the driving part 20 is set in the middle position of the protective part 10, the width direction is perpendicular to the length direction, and the length direction is the direction from the upper edge to the lower edge of the protective structure.
[0069] Specifically, when the driving part 20 includes one, the driving part 20 is arranged in the middle position along the width direction of the protective part 10, that is, the driving part 20 is arranged at the center point in the width direction of the protective part 10. This can avoid the driving part 20 being too close to one side of the protective part 10 and causing an unbalanced workload, resulting in structural instability, thereby improving the overall balance of the structure and improving the reliability of the system.
[0070] In certain embodiments, the guard portion 10 includes a guard plate having a first end and a second end. The height of at least one of the first end and the second end is adjustable along the height of the vehicle 1000. The first end comprises an upper edge of the guard portion 10, and the second end comprises a lower edge of the guard portion 10. For ease of description, the first end is used as the upper edge of the guard portion 10, and the second end as the lower edge of the guard portion 10.
[0071] The height of the first end is fixed, the height of the second end is adjustable along the height direction of the vehicle 1000, and the first end is set to be an end away from the geometric center of the vehicle 1000.
[0072] The geometric center of the vehicle 1000 may be a point on a horizontal plane determined by the intersection of the longitudinal axis of symmetry and the transverse axis of symmetry of the vehicle.
[0073] In the first state, the height of the first end is lower than or equal to the height of the second end; in the second state, the height of the first end is higher than the height of the second end.
[0074] Optionally, the protection device 100 further includes a support member 30 , one end of the support member 30 is used to be connected to the vehicle body 200 , and the other end is connected to the protection portion 10 .
[0075] The upper edge (first end) of the protection portion 10 is rotatably connected to the support member 30 .
[0076] The upper edge of the protection portion 10 and the support member 30 are rotatably connected via a hinge 40 .
[0077] For example, the support member 30 can be a bracket that connects the frame of the vehicle 1000 and the protective part 10. The bracket includes a first bracket 31 and a second bracket 32. One end of the second bracket 32 is set at an end of the first bracket 31 away from the vehicle body 200, and the first end of the protective part 10 is set at the other end of the second bracket 32.
[0078] One end of the first bracket 31 is connected to the frame of the vehicle 1000, and the other end is connected to the second bracket 32, providing a support point for the second bracket 32. One end of the second bracket 32 is connected to the first bracket 31, and the other end is connected to one end (first end) of the protective portion 10, so that the protective portion 10 can cover a larger area, that is, the protective portion 10 can achieve a wider protection function and improve the protection effect.
[0079] For another example, the bracket is set on the vehicle body 200, the first end of the protective part 10 is rotatably set on the second bracket 32, and the driving part 20 is connected to the second end of the protective part 10. Under the drive of the driving part 20, the second end of the protective part 10 can move downward. At this time, the first end of the protective part 10 rotates around the second bracket 32 to adjust the height of the second end of the protective part 10 (for example, lowering the height, etc.). For example, taking the example of the driving unit 20 driving the second end of the protective unit 10 to move downward, during the driving of the vehicle 1000, the second end of the protective unit 10 can be stored at a first height position to avoid affecting the passability and wind resistance performance of the vehicle 1000. When the information collection device 201 (such as an infrared sensor, etc.) detects that an obstacle is approaching the battery 300, the driving unit 20 can drive the second end of the protective unit 10 to move downward to a second height position, which is lower than the first height position. Before the obstacle collides with the battery 300, the protective unit 10 first intercepts the obstacle to reduce the impact energy and impact force of the obstacle, thereby preventing the obstacle from scratching the battery 300 (and other electrical components) and protecting the battery 300.
[0080] Specifically, the first end of the protective portion 10 is rotatably connected to the bracket, and the protective portion 10 can rotate around the bracket, thereby achieving adjustable position of the protective portion 10 and increasing the flexibility of the protective portion 10. The first end of the protective portion 10 is rotatably disposed at the end of the bracket away from the vehicle body 200, and the first end of the protective portion 10 and the bracket are rotatably connected via a hinge 40. Based on the hinge 40, the first end of the protective portion 10 and the end of the bracket away from the vehicle body 200 can rotate relative to each other around the central axis of the hinge 40. For example, in a case where the protective device 100 is disposed at the edge of the vehicle body 200 and is located at the rear of the vehicle 1000, based on the hinge 40, the first end of the protective portion 10 can rotate around the central axis of the hinge 40 (i.e., an axis perpendicular to the direction of travel of the vehicle 1000) relative to the end of the bracket away from the vehicle body 200, thereby increasing the flexibility and adjustability of the protective portion 10.
[0081] In some embodiments, the protective device 100 further includes a driving unit 20. In a first state, the driving unit 20 drives the second end of the protective unit 10 to move so that the height of the second end of the protective unit 10 is within a first preset height range.
[0082] In the second state, the driving part 20 drives the second end of the protection part 10 to move so that the height of the second end of the protection part 10 is located in a second preset height range, and the first preset height range and the second preset height range are different.
[0083] The minimum height of the first preset height range is greater than the maximum height of the second preset height range.
[0084] Specifically, the protective device 100 has a first mode and a second mode. The first mode can be a protection mode or an anti-collision mode for protecting the batteries 300, 300, etc., while the second mode can be a mode for accommodating the protective portion 10 to prevent the protective portion 10 from affecting the vehicle's wind resistance performance and passability. In the first mode, the drive unit 20 can drive the protective portion 10 to switch to the first state. In the first state, the drive unit 20 drives the second end of the protective portion 10 to move so that the height of the second end of the protective portion 10 is within a first preset height range, the minimum height of which is greater than the bottom height of the battery 300. This achieves the purpose of accommodating the protective portion 10 and preventing it from affecting the vehicle's wind resistance performance and passability.
[0085] In the second mode, the driving unit 20 can drive the protective unit 10 to switch to the second state. The driving unit 20 drives the second end of the protective unit 10 to move so that the height of the second end of the protective unit 10 is within a second preset height range. The second preset height range is determined based on the bottom height of the battery 300. In the second mode, the height of the second end of the protective unit 10 is always less than the bottom height of the battery 300 to ensure that when an obstacle rushes towards the vehicle 1000, the protective unit 10 can effectively protect the battery 300 and prevent the battery 300 from directly colliding with obstacles, etc., so that the protective unit 10 can provide sufficient protection and optimize the protection effect. The first preset height range and the second preset height range are different, and the minimum height of the first preset height range is greater than the maximum height of the second preset range.
[0086] See also Figure 5 and Figure 6 In some embodiments, the protected object includes a battery 300. The battery 300 includes a battery body 301 and a housing. The housing includes a first bottom plate 302 and a second bottom plate 303. The battery body 301, the first bottom plate 302, and the second bottom plate 303 are stacked, and a cavity 304 is formed between the first bottom plate 302 and the second bottom plate 303.
[0087] Glue is placed in the cavity 304 and solidifies when exposed to air.
[0088] The glue may be a quick-drying glue that can quickly complete bonding in a short time and has a strong bonding force.
[0089] Optionally, the cavity 304 includes a plurality of isolated sub-cavities, and glue is set in the sub-cavities, and the glue solidifies when exposed to air.
[0090] Optionally, a pressure sensor is further provided in the cavity 304 , and when the pressure change trend of the pressure sensor meets a preset trend, a warning instruction is issued to the controller of the vehicle 1000 .
[0091] Alternatively, the pressure sensor may be a liquid pressure sensor or the like.
[0092] Among them, the number and size of the sub-cavities are related to the size of the battery 300 and the accuracy of the detection. For example, the smaller the size of the sub-cavity, the greater the detection accuracy. The user can adaptively set the number and size of the sub-cavities according to the size of the battery 300, production cost and inspection accuracy requirements.
[0093] The preset trend may be determined based on experiments or table lookup, etc. For example, the preset trend may be a constant value; for another example, the preset trend may be decreasing first and then constant; or increasing first and then constant.
[0094] Specifically, the battery 300 includes a battery body 301 and a shell. The shell includes a first bottom plate 302 and a second bottom plate 303. The battery body 301, the first bottom plate 302, and the second bottom plate 303 are stacked. A cavity 304 is formed between the first bottom plate 302 and the second bottom plate 303. The cavity 304 can be divided into multiple mutually isolated sub-cavities. Glue and pressure sensors can be placed in the sub-cavities to obtain multiple sub-compartments. The sub-compartments are filled with glue, and the pressure sensors are immersed in the glue. Before the battery 300 is impacted, the pressure sensor can detect a fixed pressure value (assuming a first pressure value). After the battery 300 is impacted, if the sub-compartment at the bottom of the battery 300 is ruptured, the pressure detected by the pressure sensor will change (usually the pressure value detected will decrease). After the sub-compartment is ruptured, the glue overflows from the ruptured area and quickly solidifies when it comes into contact with air, thereby repairing the crack. After the repair is completed, the pressure sensor can detect that the pressure value no longer changes and is a fixed value (assuming a second pressure value), which is less than the first pressure value. If the glue has completely leaked, meaning the repair is incomplete, the pressure value detected by the pressure sensor will be less than the second pressure value. Therefore, if the pressure change trend of the pressure sensor matches the gradually decreasing pressure trend, and the pressure value is less than the second pressure value, it can be assumed that the bottom of battery 300 is damaged and cannot be repaired. At this point, a warning command can be sent to the controller of vehicle 1000, which can issue a warning message in the form of voice, text, light, etc., to warn the user to inspect and repair the bottom of battery 300.
[0095] Since pressure sensors are provided in each sub-compartment (sub-cavity), the pressure sensors can be numbered and the damaged position can be quickly located according to the number of the pressure sensors that meet the preset trend, thereby improving the inspection and repair efficiency.
[0096] Optionally, the sub-cavity can be a mosaic cavity 304 compartment, that is, each sub-cavity can be removed and replaced. If it is determined that the sub-cavity is damaged, the sub-cavity can be quickly replaced to avoid additional losses caused by overall replacement and further improve maintenance and repair efficiency.
[0097] See also Figure 7 In certain embodiments, the present application further provides a control method, which is used for the protective device 100100 and the vehicle 10001000 of any of the above embodiments. The control method includes:
[0098] Step 011: Obtain the obstacle height of the obstacle close to the vehicle 10001000;
[0099] Step 012: Based on the height of the obstacle and the height of the protected object, switch the working state of the protection unit 10, where the working state includes a first state and a second state.
[0100] Specifically, for ease of explanation, the following description uses the battery 300 as the protected object and the height of the battery 300 from the ground (hereinafter referred to as the battery 300 height) as an example. An information collection device (e.g., an infrared sensor, a laser sensor, an image sensor, a millimeter-wave radar, etc.) mounted on the vehicle 1000 1000 can scan road condition information to obtain obstacles around the vehicle 1000 1000. Then, by calculating the change in the distance between the vehicle 1000 1000 and the obstacle within a preset time, obstacles approaching the vehicle 1000 1000 are determined (e.g., obstacles whose relative distance from the vehicle 1000 1000 decreases within the preset time are determined to be obstacles approaching the vehicle 1000 1000). The obstacle height of the obstacle approaching the vehicle 1000 1000 is then analyzed and compared with the battery 300 height to switch the operating state of the protection unit 10, which includes a first state and a second state. For example, when the height of the obstacle is less than the height of the battery 300, it can be assumed that the obstacle will not collide with the battery 300, and the protective part 10 is switched to the first state to ensure the passability and wind resistance performance of the vehicle 10001000; when the height of the obstacle is greater than the height of the battery 300, the obstacle may scratch and collide with the battery 300 when passing the bottom of the vehicle 10001000, and the protective part 10 can be switched to the second state to achieve protection of the battery 300.
[0101] In this way, by obtaining the obstacle height of the obstacle close to the vehicle 10001000, the working state of the protection part 10 is switched based on the obstacle height and the protected height of the protected object, wherein the working state includes a first state and a second state. By adaptively switching the working state of the protection part 10, the flexibility of the protection device 100 is improved, and while protecting the protected object, the influence of the protection device 100 on the passability and wind resistance performance of the vehicle 10001000 is avoided.
[0102] See also Figure 8 Optionally, the protective device 100 is provided with a first mode and a second mode. In the first mode, the protective portion 10 is set to the first state; in the second mode, the protective portion 10 is set to the second state.
[0103] Step 012: Based on the height of the obstacle and the height of the protected object, the working state of the protection unit 10 is switched, including:
[0104] Step 0121: When the height of the obstacle is less than the height of the protected object, the protection device 100 is controlled to switch to the second mode;
[0105] Step 0122: When the height of the obstacle is greater than the protected height of the protected object, the protection device 100 is controlled to switch to the first mode.
[0106] Specifically, the protective device 100 has a first mode and a second mode. In the first mode, the protective portion 10 is set to the first state; in the second mode, the protective portion 10 is set to the second state. If an obstacle is higher than the battery 300, and the obstacle gradually approaches the vehicle 1000, it may collide with the battery 300 at the bottom of the vehicle 1000. By controlling the protective device 100 to switch to the second mode, the height of the lower edge (e.g., the second end) of the protective device 100 is lowered, so that the obstacle first collides with the protective portion 10 of the protective device 100 after approaching the vehicle 1000, reducing the impact force of the obstacle and effectively protecting the battery 300. If the obstacle is lower than the battery 300, the obstacle will not collide with the battery 300 of the vehicle 1000. The protective device 100 can be switched to the first mode to ensure that the height of the second end of the protective device 100 is within a first predetermined height range, thereby avoiding affecting the vehicle 1000's navigability and wind resistance.
[0107] See also Figures 9 to 11 Optionally, step 0121: controlling the protection device 100 to switch to the second mode includes:
[0108] Step 01211: Control the protection device 100 to switch to the second mode within a preset time period; and / or
[0109] Step 01212: When the distance between the obstacle and the driving unit 20 is greater than a preset distance, the protection device 100 is controlled to switch to the second mode at a preset speed.
[0110] The preset duration can be determined based on the following methods:
[0111] t1 <L1 / V
[0112] Among them, L1=L2-(H1-H0)*tanθ+L3, L1 is the distance between the impact point of the obstacle and the protective part 10 and the current position of the obstacle, L2 is the distance between the projections of the upper edge (first end) and the lower edge (second end) of the protective part 10 on the ground in the second mode, H1 is the height of the obstacle, H0 is the height of the battery 300, θ is the angle between the protective part 10 and the driving part 20 in the second mode, L3 is the distance between the current position of the obstacle and the projection of the upper edge on the ground, and V is the relative speed of the vehicle 10001000 and the obstacle.
[0113] See also Figure 11 The upper edge includes the first end, the lower edge includes the second end, and the speed at which the driving unit 20 drives the first end to move downward to achieve switching to the second mode can be adjusted. Based on the monitored driving speed of the vehicle 10001000, the height of the obstacle, and the distance between the vehicle 10001000 and the obstacle, the distance L1 between the current position of the obstacle and the impact point in the event of a collision is first determined:
[0114] L1=L11+L3
[0115] Where L11 is the distance between the impact point and the projection of the first end on the ground. The distance L1 between the current position of the obstacle and the impact point can be calculated using the following formula:
[0116] L11=L-L12
[0117] Where L12 is the distance between the impact point and the projection of the second end on the ground. The distance L12 between the impact point and the projection of the second end on the ground can be calculated using the following formula:
[0118] L12=(H1-H0)*tanθ
[0119] Therefore, the time (L1 / V) when the vehicle 10001000 collides with the obstacle can be determined by calculating the distance L1 between the current position of the obstacle and the impact point, and the relative speed between the vehicle 10001000 and the obstacle. When the time for the driving unit 20 to adjust the height of the second end to the first preset height range is less than the time, it can be determined that when the obstacle collides with the protective unit 10, the protection that the protective device 100 can provide is in place, that is, the battery 300 can be protected.
[0120] The preset distance L4 is determined based on the following formula:
[0121] L4>(t2*V)+(H1-H0)*tanθ
[0122] Wherein, t2 is the switching time of the driving unit 20 at the preset speed, V is the relative speed of the vehicle 10001000 and the obstacle, H1 is the height of the obstacle, H0 is the height of the battery 300, and θ is the angle between the protection unit 10 and the driving unit 20 in the second mode.
[0123] When the protective device 100 switches to the second mode at a preset speed, the speed is fixed. Therefore, at the preset speed, the switching time t2 of the drive unit 20 is also constant. Assume that after time t2, the obstacle collides with the vehicle 10001000. At this time, the distance moved by the obstacle is (t2*V) plus the distance L12 between the impact point and the projection of the second end on the ground, which is less than the preset distance. This indicates that when the distance between the obstacle and the drive unit 20 is greater than the preset distance, when the protective device 100 is controlled to switch to the second mode at the preset speed, after the protective device 100 completes the switch (protection is in place), there is still a safe distance (H1-H0)*tanθ between the obstacle and the drive unit 20. In other words, at this time, the obstacle impacts the protective plate, achieving protection for the battery 300.
[0124] Specifically, if the height of the obstacle is greater than the height of the battery 300, the height of the obstacle can be compared with the height of the first end of the guard 10. If the height of the obstacle is greater than the height of the first end of the guard 10, the obstacle will collide with the vehicle 1000 1000. Therefore, an obstacle warning can be issued to prompt the driver to brake or evade the obstacle, and the driver can be further reminded to take protective measures (braking or reducing speed) by controlling the seat belt to tighten. The vehicle 1000 1000 can also be controlled to perform emergency braking and / or emergency evasion to further improve driving safety. If the height of the obstacle is greater than the height of the battery 300 and the height of the obstacle is less than the height of the first end of the guard 10, the guard 100 can be controlled to switch to the second mode within a preset time period and / or, if the distance between the obstacle and the driving unit 20 is greater than a preset distance, the guard 100 can be controlled to switch to the second mode at a preset speed to effectively protect the battery 300 and avoid the risk of collision with the battery 300.
[0125] It should be noted that in the second mode, the angle θ between the protection part 10 and the driving part 20 can be determined according to the ground clearance of the vehicle 10001000 and the required protection performance. For example, the larger the angle θ, the better the protection performance.
[0126] See also Figure 12 In order to facilitate better implementation of the control method of the embodiment of the present application, the embodiment of the present application also provides a control device 400, which is applied to a protective device, and the protective device is connected to the frame of the vehicle.

[0127] In some embodiments, the switching module 402 is specifically used to control the protection device to switch to the second mode when the height of the obstacle is less than the protected height of the protected object; and to control the protection device to switch to the first mode when the height of the obstacle is greater than the protected height of the protected object.
[0128] In some embodiments, the protective device also includes a driving unit, and the switching module 402 is specifically used to control the protective device to switch to the second mode within a preset time period; and / or when the distance between the obstacle and the driving unit is greater than or equal to a preset distance, control the protective device to switch to the second mode at a preset speed.
