Fenders and vehicles Technical Field
[0001] The present application relates to the technical field of vehicles, and more particularly, to a fender and a vehicle. Background Art
[0002] At present, with the rapid development of automation and intelligence, new energy vehicles are becoming more and more popular and purchased by the public; as the sales of new energy vehicles increase and the frequency of use increases, the driving conditions and usage scenarios become more complex and changeable, and battery safety is therefore facing more severe challenges.
[0003] How to improve safety is a research direction in vehicle technology.
[0004] Summary of the Invention
[0005] The present application provides a fender and a vehicle, which can improve safety.
[0006] In a first aspect, an embodiment of the present application provides a protective plate for connecting a battery. The protective plate is provided with a first channel and a second channel inside, and the second channel is provided on a side of the first channel away from the battery.
[0007] When the side of the protective plate facing away from the battery is impacted, both the first and second channels absorb energy and reduce shock, creating a double layer of protection, reducing the amplitude of battery vibration and improving safety. The presence of both channels also reduces the weight of the protective plate.
[0008] In some embodiments, the protective plate includes a first plate body, a second plate body, and a support body, wherein the first plate body and the second plate body are arranged opposite to each other along the thickness direction of the protective plate, and the support body is arranged between the first plate body and the second plate body. The first channel and the second channel are formed between the first plate body and the second plate body.
[0009] In some embodiments, the support body and the first plate body form a first channel, and the support body and the second plate body form a second channel.
[0010] The support body can prop the first plate body and the second plate body apart to form a first channel and a second channel between the first plate body and the second plate body. By using the first plate body and the second plate body to enclose the first channel and the second channel, the volume and weight of the support body can be reduced.
[0011] In some embodiments, at least one of the first channel and the second channel is surrounded by a support body. Enclosing at least one of the first channel and the second channel by a support body can make the shape design of the first channel and the second channel more flexible and improve the strength of the periphery of the first channel or the periphery of the second channel.
[0012] In some embodiments, the first plate body, the second plate body and the support body are formed as an integral structure, thereby simplifying the molding process of the protective plate, improving the overall strength and rigidity of the protective plate, reducing the risk of the protective plate being crushed, and improving safety.
[0013] In some embodiments, the cross-section of the first channel is trapezoidal, rectangular, triangular, semicircular, circular, or racetrack-shaped, and the cross-section of the second channel is trapezoidal, rectangular, triangular, semicircular, circular, or racetrack-shaped.
[0014] The first channel and the second channel can adopt various shapes according to needs, which helps to improve the versatility and diversity of the protective plate.
[0015] In some embodiments, the first channel and the second channel both extend along a first direction, and the first channel and the second channel are stacked along a thickness direction of the protective plate; the first direction is perpendicular to the thickness direction.
[0016] The first channel and the second channel extend along the first direction, which can enhance the strength and rigidity of the protective plate along the first direction; the protective plate has a strong anti-deformation ability. When the protective plate is impacted or collided in the first direction, the deformation of the protective plate can be reduced, thereby effectively protecting the battery and reducing the size of other components invading the battery.
[0017] In some embodiments, the protective plate includes a plurality of first channels and a plurality of second channels, wherein the plurality of first channels are arranged along the second direction, and the plurality of second channels are arranged along the second direction, with the thickness direction, the first direction, and the second direction being perpendicular to each other. At least one second channel is provided on a side of each first channel facing away from the battery.
[0018] By creating multiple first channels and multiple second channels, a honeycomb structure can be formed inside the protective plate. This application utilizes the mechanical support and crush energy absorption of the honeycomb structure to effectively protect the battery, reduce the impact on the battery, and improve battery safety.
[0019] In some embodiments, at least a portion of the first channel is used for allowing a heat exchange medium to flow.
[0020] The first channel of the protective plate is used for heat exchange, creating a large heat exchange area between the protective plate and the battery, thereby improving heat exchange efficiency and response speed. The protective plate integrates protection and heat exchange functions, simplifying the vehicle's structure and improving its range. The second channel, located on the side of the first channel facing away from the battery, serves as an insulating and protective layer. When the protective plate is impacted, the second channel isolates the first channel from external impact, minimizing deformation of the first channel, reducing the risk of heat exchange medium leakage, and improving safety.
[0021] In some embodiments, the protective plate includes a plate body, an inlet pipe, and an outlet pipe. The plate body is provided with a first channel and a second channel. The inlet pipe and the outlet pipe are respectively provided on either side of the plate body along a first direction. The first channel for allowing the heat exchange medium to flow is connected to the inlet pipe and the outlet pipe.
[0022] By integrating an inlet pipe and an outlet pipe on the protective plate, the protective plate is connected to the heat exchange system of the vehicle, thereby simplifying the structure of the vehicle.
[0023] In some embodiments, the protective plate includes a plurality of channel groups spaced apart along the second direction, each channel group including at least one first channel and at least one second channel; a third channel is formed between adjacent channel groups. The provision of the third channel further reduces the weight of the protective plate.
[0024] In a second aspect, some embodiments of the present application provide a vehicle, comprising a battery and the protective plate provided by any embodiment of the first aspect, wherein the battery is connected to the protective plate.
[0025] In some embodiments, the vehicle includes a floor, the floor includes a protective plate, and the battery is disposed on a lower side of the protective plate.
[0026] The protective plate can increase the overall rigidity of the vehicle body, reduce the risk of the vehicle body being crushed in a collision, and improve safety. The protective plate can also resist the impact from above the battery, reducing the amplitude of battery vibration and improving safety.
[0027] In some embodiments, the extension direction of the first channel is perpendicular to the front-rear direction of the vehicle and the thickness direction of the fender, and the extension direction of the second channel is perpendicular to the front-rear direction of the vehicle and the thickness direction of the fender.
[0028] The protective plate has high strength and rigidity in the extension direction of the first channel, and can protect the battery in the extension direction of the first channel, while the vehicle body can protect the battery in the front and rear directions, thereby achieving all-round protection of the battery, reducing the deformation of the battery when the vehicle collides, reducing the risk of battery fire and explosion, and improving safety.
[0029] In some embodiments, the vehicle further includes a seat mounted to the fender.
[0030] The fender's high strength eliminates the need for traditional seat crossbars, allowing seats to be mounted to multiple locations on the fender, making it adaptable to a wider range of vehicle compartments. The fender's high flatness allows for flexible seat positioning, further enhancing the intelligent cockpit.
[0031] In some embodiments, the vehicle includes a floor, the battery is disposed on a lower side of the floor, and the protective plate is disposed on a lower side of the battery.
[0032] During driving, the protective plate blocks road debris and reduces the risk of battery damage. Both the first and second channels of the protective plate absorb energy and reduce shock, creating a double layer of protection that reduces battery vibration and improves safety.

[0054] The driving conditions and usage scenarios of new energy vehicles are complex and changeable, which poses severe challenges to battery safety.
[0055] The inventor tried to set a protective plate on the outside of the battery, which can reduce the impact on the battery and improve the safety of the battery.
[0056] The inventors noticed that when the car vibrates, the protective plate has a poor shock-absorbing effect, causing the force transmitted to the battery to be too large, making the battery prone to strong vibrations and posing a safety hazard.

The first channels 7a for the heat exchange medium 8 may also be referred to as heat exchange channels. The number of heat exchange channels may be adaptively selected based on the heat exchange intensity requirements of different batteries 2.
[0111] In the embodiment of the present application, the first channel 7a of the protective plate 7 can be used by the heat exchange medium 8. The heat exchange area between the protective plate 7 and the battery 2 is large, thereby improving the heat exchange efficiency and the response speed. The protective plate 7 integrates the protection function and the heat exchange function, which can simplify the structure of the vehicle 1 and improve the endurance of the vehicle 1. The second channel 7b is located on the side of the first channel 7a away from the battery 2 to serve as an isolation protection layer; when the protective plate 7 is impacted, such as by a falling hammer, stepping on, or impact by a child seat leg, the second channel 7b can isolate the first channel 7a from the external impact, thereby reducing the deformation of the first channel 7a, reducing the risk of leakage of the heat exchange medium 8, and improving safety.
[0112] In some embodiments, all first channels 7a can be used as heat exchange channels. The embodiment of the present application can increase the heat exchange area of the protective plate 7, improve the heat exchange efficiency, and increase the response speed.
