[0002] The battery pack of new energy vehicles is usually installed in the chassis of the vehicle body. The sides of the battery pack are generally protected by structures such as door sill beams to improve the safety of the battery pack in the event of a side collision.

[0003] Due to the fit gap between the battery pack and the sill beam, in order to improve the protection performance and aerodynamic performance, some related technologies will also add a guard plate on the sill beam.

[0034] Reference Figure 1 In some related technologies, a guard plate 110 is provided on the vehicle's rocker beam 210. The guard plate 110 extends toward the direction of the battery pack 220 and blocks the fitting gap between the rocker beam 210 and the battery pack 220 from the bottom of the vehicle, thereby improving the protection effect of the battery pack 220 while improving the aerodynamic performance of the bottom of the vehicle.

[0035] However, installing the guard plate 110 will occupy space on the threshold beam 210, resulting in an inability to install a hidden foot pedal on the threshold beam 210, which has a negative impact on the user's experience.

[0036] To this end, the present application provides a method for using a guard plate, which helps to improve the functionality of the guard plate 110, so as to provide the user with a foot pedal while improving aerodynamic performance, thereby enhancing the user's experience.

[0037] The method for using the guard plate according to an embodiment of the present application includes:

[0038] Providing a guard plate 110 movably mounted on the door sill beam 210 ;

[0039] The control guard plate 110 switches between a first mode and a second mode. In the first mode, the guard plate 110 is retracted into the vehicle, and the guard plate 110 extends from the door sill beam 210 to the bottom of the battery pack 220 to cover the fitting gap between the battery pack 220 and the door sill beam 210. In the second mode, the guard plate 110 is extended from the vehicle to provide a foot pedal for the user.

[0040] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 For example, the present application further provides a battery pack protection device embodiment for implementing the protective plate use method of the present application, wherein the battery pack protection device includes a protective plate 110, Figures 2 to 5The process of switching the battery pack protection device from the first mode to the second mode under the control of the guard plate usage method is exemplified. In addition, the present application also provides a vehicle having the battery pack protection device of the present application.

[0041] It can be understood that the body of the vehicle can be divided into structural parts (such as the rocker beam 210) and the covering part 230. The covering part 230 forms the overall outer contour of the vehicle body. "The guard plate 110 is retracted into the vehicle" means that the projection of the guard plate 110 on the horizontal plane is within the range of the outer contour, thereby being hidden in the covering part 230, and "the guard plate 110 extends from the vehicle" means that at least a part of the guard plate 110 extends outside the covering part 230, thereby allowing the user to step on it.

[0042] According to the method for using the guard plate of the present application, on the one hand, the method for using the guard plate controls the guard plate 110 to block the fitting gap between the battery pack 220 and the door sill beam 210 in the first mode, thereby producing a windproof effect and preventing air from flowing into the fitting gap from below, thereby being able to guide the air under the battery pack 220 during driving, thereby improving the aerodynamic performance of the vehicle; on the other hand, the method for using the guard plate controls the guard plate 110 to be extended in the second mode to be used as a foot pedal, thereby improving the functionality of the guard plate 110, overcoming the problem that the guard plate 110 occupies the space on the door sill beam 210, making it impossible to install the foot pedal, and helping to improve the user experience.

[0043] The battery pack protection device and the vehicle having the battery pack protection device also have the beneficial effects provided by the method of using the guard plate, which will not be described in detail here.

[0044] Optionally, to further improve aerodynamic performance, in some embodiments, in the first mode, the guard plate 110 abuts against the lower surface of the battery pack 220. By ensuring that the guard plate 110 is in contact with the battery pack 220, airflow can be prevented from passing through the gap between the guard plate 110 and the battery pack 220 during vehicle operation, thereby preventing negative disturbances (such as vibration of the guard plate 110 caused by airflow or noise generated in the gap).

[0045] In some embodiments, the guard plate 110 is further provided with a sealing surface, and in a first mode, the sealing surface faces upward to abut against the lower surface of the battery pack 220. Providing the sealing surface can further enhance the tightness of the contact between the guard plate 110 and the battery pack 220 and better eliminate disturbances.

[0046] The protective plate 110 can be provided with a sealing surface in various ways, as long as the requirements of the protective plate's usage are met. For example, in some embodiments, a sealing gasket 120 is provided on the protective plate 110. It is understood that the sealing gasket 120 is capable of elastic deformation. When the protective plate 110 is in the first mode, the sealing gasket 120 contacts the battery pack 220 and, under the compressive action of the battery pack 220 and the protective plate 110, fills and seals the gap between the battery pack 220 and the protective plate 110.

[0047] Alternatively, in some embodiments, the shield 110 may be composed of a rigid core plate and an elastic surface layer wrapped around the core plate. The core plate provides strength to maintain the basic shape of the shield 110, while the surface layer contacts and deforms with the battery pack 220 in the first mode, thereby creating a seal. The surface layer may be plastic, rubber, or other commonly used elastic materials, and may be bonded to the core plate through processes such as injection molding.

[0048] In some embodiments, the guard plate 110 is further provided with an anti-slip surface. In the second mode, the anti-slip surface faces upward, so that the guard plate 110 has anti-slip performance, thereby improving the user experience.

[0049] Various methods can be used to provide a non-slip surface for the guard plate 110, as long as they meet the requirements of the guard plate's usage. For example, in some embodiments, the guard plate 110 is provided with a non-slip pad 130. It is understood that the non-slip pad 130 has a high coefficient of friction, thereby achieving a non-slip effect. For example, the non-slip pad can be made of a material with a high coefficient of friction, or it can be made with non-slip textures or non-slip flocking. Of course, in other embodiments, non-slip textures can also be directly formed on the guard plate 110 to form a non-slip surface, and this is not limited here.

[0050] It should be pointed out that when used as a foot pedal, impurities such as stones and dirt may remain on the surface of the guard plate 110. In rainy and snowy weather conditions, there may also be accumulated water on the surface of the guard plate 110, which may cause damage to the battery pack 220. Larger stone particles may also affect the sealing effect between the guard plate 110 and the battery pack 220. Therefore, although the sealing surface and the anti-slip surface can sometimes be designed in the same way (for example, the sealing gasket 120 and the anti-slip gasket 130 are both made of the same elastic material with a large friction coefficient), preferably, the sealing surface and the anti-slip surface are different surfaces.

[0051] For example, in some embodiments, the sealing surface and the anti-slip surface are respectively located on opposite sides of the guard plate 110 . For example, the sealing pad 120 and the anti-slip pad 130 may be respectively provided on both sides of the guard plate 110 .

[0052] Correspondingly, in the method of using the guard plate, the guard plate 110 is turned over so that the sealing surface and the anti-slip surface are switched to face upward.

[0053] In other words, in the second mode, the sealing surface is the lower surface of the guard plate 110, and the anti-slip surface is the upper surface of the guard plate 110. The sealing surface is not prone to accumulation of water, stones, dirt or other impurities, thereby reducing the risk of damage to the battery pack 220. In the first mode, the sealing surface is the upper surface of the guard plate 110, and the anti-slip surface is the lower surface of the guard plate 110. The impurities originally remaining on the anti-slip surface can be automatically separated from the anti-slip surface under the influence of its own gravity and vehicle vibration, so that the anti-slip surface has a certain self-cleaning ability.

[0054] The guard plate 110 can be switched between the first and second modes in a variety of ways. Optionally, in some embodiments, the battery pack protection device includes a flexible arm fixedly mounted on the door sill beam 210 , with the guard plate 110 mounted on the flexible arm, which can drive the guard plate 110 to switch between the first and second modes.

[0055] It is understood that the flexible arm has multiple degrees of freedom, thereby increasing the flexibility and range of motion of the guard plate 110. For example, in some embodiments, the flexible arm includes a base 140 and arm sections, wherein the base 140 is fixedly mounted on the bottom of the door sill beam 210, and the arm sections are hingedly connected to the base 140 and the guard plate 110.

[0056] The arm section can provide the guard plate 110 with freedom of movement, so that the guard plate 110 can cover the fitting gap on the inside of the vehicle in the first mode, and extend to the outside of the vehicle body to provide a foot pedal for the user in the second mode. The arm section can also provide rotational freedom, so that the guard plate 110 can be flipped over, so that a sealing surface is used to contact the battery pack 220 in the first mode, and a non-slip surface is used for the user to step on in the second mode.

[0057] Specifically, the flexible arm can have multiple arm sections, refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In some implementations, the arm section includes a first arm section 150 and a second arm section 160, and the base 140, the first arm section 150, the second arm section 160, and the guard plate 110 are sequentially hingedly connected. This provides the flexible arm with three joints (i.e., hinged locations), thereby providing greater flexibility and facilitating more refined design of the movement trajectory of the flexible arm and guard plate 110, facilitating avoidance of other vehicle structures during movement and / or ensuring a more reasonable position of the flexible arm and guard plate 110 when stationary (i.e., the positions in the first and second modes).

[0058] For example, refer to Figure 5 In some embodiments, in the first mode, the first arm section 150 and the second arm section 160 are retracted into the vehicle, and in the second mode, the first arm section 150 extends outward from the sill beam 210 to extend from the bottom of the sill beam 210, and the second arm section 160 extends upward at an angle to raise the guard plate 110 relative to the first mode.

[0059] It is understandable that in the first mode, the guard plate 110 needs to be at a relatively low horizontal height (lower than the battery pack 220) to achieve a shielding effect. If in the second mode, the guard plate 110 is still at the same height as the first mode, the vertical distance between the guard plate 110 and the vehicle door will be too large, reducing the user's experience when lifting their legs from the guard plate 110 and stepping into the vehicle door.

[0060] By lifting the guard plate 110 to a suitable height, this problem can be overcome and the user experience can be improved. The first arm section 150 and the second arm section 160 cooperate to complete the lifting of the height of the guard plate 110 and the movement to the outside, which can effectively avoid other parts on the vehicle (such as Figure 2 The cover 230 of the vehicle shown in FIG. 1 is provided to avoid interference.

[0061] Of course, the number of arm sections can be further increased based on the actual design requirements (e.g., position and motion trajectory) of the guard plate 110, which will not be further elaborated here. For example, under the premise of meeting the design requirements, the first arm section 150 and the second arm section 160 can be plates, rods, or parts of other shapes and specifications, which are not limited in this application.

[0062] Furthermore, in some embodiments, in the second mode, the second arm section 160 abuts against an outer surface of the vehicle, and the shape of the second arm section 160 matches the outer shape of the vehicle (ie, the cover 230 forming the outer contour of the vehicle).

[0063] For example, refer to Figure 5 The second arm section 160 adopts a curvature design. Specifically, in some embodiments, the portion of the second arm section 160 close to the cover 230 has a curvature that is substantially consistent with the surface of the cover 230, thereby avoiding a sudden change in the vehicle's appearance and improving the vehicle's aesthetics.

[0064] Of course, the adaptation referred to in this application should depend on the overall design concept of the vehicle, and is not limited to Figure 5 As shown in the design, the second arm section 160 can adopt different design methods based on the specific design of the vehicle, as long as it can coordinate with the surrounding cover 230 to enhance the aesthetic effect.

[0065] It should also be pointed out that Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The basic main structure of the battery pack protection device is only shown by way of example. The battery pack protection device also includes a driver, which is an active component and is used to drive the guard plate 110 to move (for example, drive the various joints of the flexible arm to rotate).

[0066] The driver can adopt existing related technologies, such as rotary motors, linear motors, linear cylinders, etc., and connect and drive the flexible arm through conventional connection methods. In actual implementation plans, the structure of the flexible arm may change according to the specifications of the specific driver used.

[0067] For example, when using a rotary motor as the driver of the flexible arm, the rotary motor can be directly installed at the various joints of the flexible arm, and the shape and size of the hinged part will change accordingly; when using a linear cylinder as the driver of the flexible arm, since the linear motion of the driver needs to be converted into the rotational motion of each arm segment and the guard plate 110, the driver needs to be connected to the arm segment and / or the guard plate 110 through a connecting rod or other transmission mechanism, so the battery pack protection device also needs to add a related transmission mechanism.

[0068] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
