[0025] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for the purpose of explaining the present application, and should not be understood as a limitation of the present application.

[0026] The core of the present application is to provide a vehicle bottom protection device and a vehicle, which can effectively prevent the vehicle body sheet metal part at the bottom of the vehicle body from being corroded.

[0027] In order to enable those skilled in the art to better understand the technical solutions provided by the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0028] Specifically, referring to Figs. 1-2 The present application provides a vehicle bottom protection device, which comprises a bottom protection plate 1.

[0029] The bottom protection plate 1 is arranged below the vehicle body sheet metal part 4 at the bottom of the vehicle, and the bottom protection plate 1 serves as a protection structure capable of covering the easily corroded area of the vehicle body sheet metal part 4, so as to avoid direct contact of mud with the vehicle body sheet metal part 4, thereby preventing the vehicle body sheet metal part 4 from being corroded.

[0030] The side edges of the bottom protection plate 1 are covered and fixed on the vehicle by the wheel arch 2 of the vehicle, and the front side edges of the bottom protection plate 1 are connected with the foot guard plate 3 of the vehicle. The wheel arch is usually installed on the upper part of the tire of the vehicle, and mainly serves to decorate and reduce the wind resistance coefficient. The foot guard plate 3 is located on the inner side of the foot pedal at both sides of the vehicle body sheet metal part 4, and serves as a part for providing support for the foot pedal and protecting the side of the vehicle body.

[0031] The vehicle bottom protection device provided by the present application can avoid direct contact of mud with the vehicle body sheet metal part 4 by arranging the bottom protection plate 1 below the vehicle body sheet metal part 4 prone to corrosion, thereby preventing the vehicle body sheet metal part 4 from being corroded. Meanwhile, the side edges of the bottom protection plate 1 are covered and fixed on the vehicle by the wheel arch 2 of the vehicle, and the front side edges of the bottom protection plate 1 are connected with the foot guard plate 3 of the vehicle, so as to realize mutual connection of the bottom protection plate 1 and each component at the bottom of the vehicle, form an integral structure, and realize stable connection. The protection of the structure at the bottom of the vehicle can also be improved.

[0032] Vehicles equipped with a bottom protection plate 1 have certain resistance to dirt and stone chips. However, since the bottom protection plate 1 is usually made of hard materials, its noise reduction and sound insulation effects are not good. To solve the above problems, in a specific embodiment, a sound-absorbing and heat-insulating pad 5 is installed between the bottom protection plate 1 and the vehicle body sheet metal part 4. To facilitate the installation of the sound-absorbing and heat-insulating pad 5, a space is reserved between the bottom protection plate 1 and the vehicle body sheet metal part 4. The reserved space is relatively dry, and by adding the sound-absorbing and heat-insulating pad 5, the sound absorption and heat insulation effect is further improved.

[0033] Specifically, the sound-absorbing and heat-insulating pad 5 is made of sound-absorbing and heat-insulating cotton. More specifically, it can be heat-insulating aluminum foil sound-absorbing cotton, a composite material combining the properties of aluminum foil and sound-absorbing cotton. In addition to heat insulation and sound absorption, it also possesses flame-retardant and high-temperature resistant properties. The protective device equipped with the sound-absorbing and heat-insulating pad 5 has a significant positive effect on reducing various noises generated by the tires below, ensuring stable temperature inside the vehicle body, especially the front, and improving the vehicle's heat insulation performance.

[0034] Of course, the sound-absorbing and heat-insulating pad 5 can also be made of other composite materials that can provide sound absorption and heat insulation effects.

[0035] In a specific embodiment, the bottom protective plate 1 is a fiber compressed plate. Fiber compressed materials have better sound absorption and heat insulation effects than plastic materials. In addition, while improving the performance against dirt brought in by the tires below and external splashes during driving, it provides a lightweight option, greatly improving the corrosion resistance and resistance to external damage of the vehicle body sheet metal parts 4, as well as the overall lightweight design.

[0036] In addition to covering the side edge of the underbody protection plate 1 with the wheel arches 2 to prevent the edge from being exposed, the edge of the underbody protection plate 1 is tightly fitted to all components of the vehicle's underside. Specifically, after the underbody protection plate 1 is assembled with the various components of the vehicle's underside (such as the wheel arches 2 and footrests 3), the gaps between the components are completely covered, preventing exposed corners and avoiding the problem of exposed body sheet metal parts 4. It can effectively prevent external dirt and corrosion from accumulating.

[0037] like Fig. 2 As shown, the bottom protective plate 1 is U-shaped. The concave surface of the bottom protective plate 1 is close to the vehicle body sheet metal part 4. The outer edge of the bottom protective plate 1 has a flange. The flange can abut against the edge of the wheel arch 2, so that the wheel arch 2 covers the side edge of the bottom protective plate 1.

[0038] In addition, this solution also provides a vehicle, including a body sheet metal part 4, wheel arches 2, foot protection plates 3, and a vehicle bottom protection device as described above.

[0039] Obviously, vehicles equipped with the aforementioned underbody protection devices have the same beneficial effects, which will not be elaborated upon here.

[0040] The vehicle can be a large commercial vehicle such as a truck, a tractor, or a passenger car, and can be adaptively selected according to actual needs.

[0041] When the vehicle is a truck, the vehicle bottom protection device is located below the truck head, and the truck head is turned over relative to the vehicle body through a turnover mechanism. The bottom protection plate 1 realizes protection around the bottom of the cab, greatly improves the corrosion resistance, stone impact resistance and heat preservation and noise reduction effect of the vehicle body sheet metal part 4.

[0042] In the actual assembly process, first, the foot guard plate 3 is installed on the vehicle body, and then the sound-absorbing and heat-insulating pad 5 is combined with the bottom protection plate 1 by pasting to form a combined part. The combined part is fastened on the vehicle body sheet metal part 4 for assembly and fixation, and finally the wheel arch 2 is assembled to complete the overall assembly. Through the combination of the bottom protection plate 1, the wheel arch 2, the foot guard plate 3 and the sound-absorbing and heat-insulating pad 5 on the vehicle body sheet metal part 4, an interlocking relationship is formed between the components, and a full-range overall protection device is formed for the vehicle body sheet metal part 4.

[0043] After assembly, the gaps between the components are shielded, there is no exposed sheet metal problem, and external dirt and corrosive substances can be effectively blocked. During routine cleaning and maintenance, the cab can be turned over as a whole through the turnover mechanism provided on the cab body, and then water washing and maintenance can be performed, which is convenient for maintenance and cleaning.

[0044] In the description of the present application, it should be understood that the orientation description, such as the orientation or position relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0045] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be mutually referred to.

[0046] The principles and implementation modes of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principles of the present application, the present application can be improved and modified in many ways.
