Description

Technical Field

[0001] The utility model relates to the technical field of automobile injection molding or die-casting flat panels, in particular to a large flat panel with a high modality and an automobile. Background Art

[0002] The large flat panel widely used in existing vehicles is usually formed by injection molding or die casting, and its structure includes a flat main body 12 and multiple mounting parts 11 distributed around the edges. However, due to the large area of ​​the large flat panel, if its modal performance is insufficient, it is easy to resonate with the vehicle body during the driving process. This resonance may not only cause the large flat panel to deform or even be damaged, but also generate unnecessary noise, affecting the riding experience of passengers.

[0003] In order to effectively improve the modal performance of the large flat panel, a method currently adopted is to set a plurality of transverse and longitudinal reinforcing ribs on the back of the main body 12, and make them cross to form a lattice-shaped reinforcing structure 13. Although this design can enhance the modal of the large flat panel to a certain extent, its disadvantage is that its material utilization rate is low, a lot of waste is generated, and the modal improvement effect is not significant.

[0004] Therefore, it is necessary to develop a new large flat panel and car with high modality. Summary of the invention

[0005] The utility model aims to provide a large flat panel and a car with high modality, which can improve the modality of the large flat panel.

[0006] In the first aspect, the utility model discloses a large flat plate with a high modality, comprising a flat plate body and mounting points arranged on the edges of the flat plate body. The flat plate body is provided with a plurality of strip ribs radially arranged around a preset point, and the preset point is located in the middle of the flat plate body.

[0007] Optionally, the preset point is the geometric center point of all mounting points on the flat panel. In practical applications, the amplitude at the geometric center point of all mounting points is usually the largest and the energy is most concentrated. Setting the preset point as the geometric center point of all mounting points can maximize the structural strength and natural mode of the large flat panel and avoid the occurrence of resonance.

[0008] Optionally, the outer ends of the strip ribs are connected to the mounting points. It is best to connect each mounting point with a rib to further improve the overall rigidity of the large plate.

[0009] Optionally, the flat plate body is further provided with a circular reinforcing rib with a preset point as the center. The design of the circular reinforcing rib can further improve the overall rigidity of the large flat plate.

[0010] Optionally, three circular reinforcing ribs with a preset point as the center are arranged at intervals on the flat plate body, which can further improve the overall rigidity of the large flat plate.

[0011] Optionally, the height of the strip ribs increases gradually from the inside to the outside. This design significantly reduces the overall weight of the large flat plate. Since the mode is inversely correlated with the weight, the modal performance of the large flat plate can be improved by reducing its weight.

[0012] Optionally, the strip ribs are arranged on the inner surface of the flat plate body. When the large flat plate is used as a cover plate of a controller on a vehicle, it can beautify the appearance of the controller.

[0013] Optionally, the circular reinforcing ribs are arranged on the inner surface of the flat plate body. When the large flat plate is used as a cover plate of a controller on a vehicle, it can beautify the appearance of the controller.

[0014] In a second aspect, a car according to the present invention adopts a large flat panel with a high modality as described in the present invention.

[0015] Beneficial effects of the utility model: The large flat panel with high modality described in the utility model greatly improves the rigidity of the large flat panel by arranging radially distributed strip ribs on the large flat panel. At the same time, the height of the strip ribs is designed to be a structure that gradually increases from the inside to the outside, and this structure can reduce the overall weight of the large flat panel. Because the mode is positively correlated with the rigidity, and the mode is negatively correlated with the weight, the utility model optimizes the modal performance of the large flat panel by increasing the rigidity and reducing the weight. This large flat panel with high modality not only has a longer service life, but can also effectively avoid unnecessary noise during use, thereby improving the riding experience of passengers.

[0021] The following will refer to the accompanying drawings and preferred embodiments to illustrate the implementation of the utility model. Those skilled in the art can understand other advantages and effects of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the utility model. It should be understood that the preferred embodiments are only for illustrating the utility model, not for limiting the scope of protection of the utility model.

[0022] like Figure 2 As shown, in an embodiment of the present application, a large flat panel with a high modality includes a flat panel body 22 and mounting points 21 arranged on the edges of the flat panel body 22. A plurality of strip ribs 23 are arranged radially around a preset point 24 on the flat panel body 22, and the preset point 24 is located in the middle of the flat panel body 22.

[0023] like Figure 2 As shown, in the embodiment of the present application, the plurality of strip ribs 23 are arranged radially outward with the middle of the flat plate body 22 as the center, that is, compared with the grid-shaped reinforcement structure 13 in the prior art (see Figure 1 ), the structural strength of the large flat panel is improved. Since the modal performance is proportional to the stiffness, this embodiment improves the structural strength of the large flat panel, thereby improving the overall natural mode of the large flat panel, thereby avoiding the occurrence of resonance. When the large flat panel with a high modality is applied to a vehicle, the whistling sound of the whole vehicle is effectively avoided, and the driving experience is improved.

[0024] In the embodiment of the present application, a large flat plate with a high modulus is formed by injection molding or die casting.

[0025] like Figure 2 As shown, in a possible embodiment, the preset point 24 is the geometric center point of all the mounting points 21 on the flat plate body 22. In practical applications, the amplitude at the geometric center point of all the mounting points 21 is usually the largest and the energy is most concentrated. Setting the preset point 24 as the geometric center point of all the mounting points 21 can maximize the structural strength and natural mode of the large flat plate and avoid the occurrence of resonance.

[0026] like Figure 2 As shown, in a possible embodiment, the outer end of the strip rib 23 is connected to the mounting point 21. Each mounting point 21 is connected with a rib as much as possible, which further improves the overall rigidity of the large plate.

[0027] like Figure 2As shown, in a possible embodiment, a circular reinforcing rib 25 with a preset point 24 as the center is further provided on the flat plate body 22. The design of the circular reinforcing rib 25 can further improve the overall rigidity of the large flat plate. The number of the circular reinforcing ribs 25 is determined according to the size of the large flat plate. Preferably, three circular reinforcing ribs 25 are provided on the flat plate body 22 at intervals.

[0028] like Figure 3 As shown, in a possible embodiment, the height of the strip ribs 23 gradually increases from the inside to the outside. This design can significantly reduce the overall weight of the large flat panel, and since the mode is inversely correlated with the weight, the modal performance of the large flat panel is effectively improved.

[0029] like Figure 2 As shown, in a possible embodiment, the strip ribs 23 and the circular reinforcing ribs 25 can be arranged on the inner surface of the flat plate body 22, or on the outer surface of the flat plate body 22, and can be specifically designed according to actual needs. Preferably, the strip ribs 23 and the circular reinforcing ribs 25 are both arranged on the inner surface of the flat plate body 22. When the large flat plate is used as a cover plate of a controller on a vehicle, the strip ribs 23 and the circular reinforcing ribs 25 are both arranged on the inner surface of the flat plate body 22, which can beautify the appearance of the controller.

[0030] In an embodiment of the present application, a car adopts a large flat panel with a high modality as described in the embodiment of the present application.

[0031] The above-mentioned embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above-mentioned embodiments. Any other changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement modes and shall be included in the protection scope of the present invention.
