[0024] The vehicle door inner panel in the present application can be applied to related structures of vehicles, rail transit or industrial equipment, etc. In the present application, the application of the vehicle door inner panel in the vehicle will be taken as an example for description.

[0025] Please refer to Figure 1 , Figure 1 is the overall structure schematic diagram of an embodiment of the vehicle door inner panel of the present application.

[0026] In an aspect of the present application, a vehicle door inner panel 10 is provided, which comprises a window body part 111 and a body part 112. On the inner side of the vehicle door inner panel 10, the connecting area of the window body part 111 and the body part 112 is convexly formed with a first reinforcing cavity 113; the inner side of the body part 112 is provided with a mounting area for mounting a loudspeaker, the mounting area is convexly formed with a second reinforcing cavity 114 towards the inner side of the vehicle door inner panel 10, the first reinforcing cavity 113 extends along a first direction X, the second reinforcing cavity 114 extends along a second direction Y, the first reinforcing cavity 113 and the second reinforcing cavity 114 are communicated; wherein the first direction X and the second direction Y intersect.

[0027] As can be seen from the above structure, since the window body part 111 is provided with an opening for mounting a window, the connection area between the window body part 111 and the body part 112 is often weak in structural strength. In the present application, the first reinforcing cavity 113 is protrudingly formed at the connection area between the window body part 111 and the body part 112, so as to improve the structural strength of the connection area between the window body part 111 and the body part 112, and further improve the structural strength of the door inner panel 10. Since the loudspeaker has a certain volume, the second reinforcing cavity 114 is protrudingly formed at the mounting area of the loudspeaker towards the inner side of the door inner panel 10, so that the second reinforcing cavity 114 can cover the loudspeaker, which not only improves the sound effect of the loudspeaker, but also protects the loudspeaker to a certain extent, and on the other hand, it can also enhance the structural strength of the door inner panel 10 and the overall design of the door inner panel 10. In addition, the first reinforcing cavity 113 and the second reinforcing cavity 114 are both protrudingly formed from the door inner panel 10. Compared with the way of additionally setting a reinforcing structure on the inner side of the door inner panel 10, the present application can form a reinforcing structure by using the structure of the door inner panel 10 itself, which on the one hand can enhance the strength of the door inner panel 10 to reduce the optimization of the strength of the door inner panel 10 in the later stage, and on the other hand, it can also effectively reduce the number of reinforcing structure parts, and further reduce the weight of the door inner panel 10 to realize the lightweight setting.

[0028] Further, the first reinforcing cavity 113 and the second reinforcing cavity 114 are in communication, so that the reinforcing structure feature is not disconnected in the middle, which on the one hand can improve the design of the door inner panel 10, and on the other hand can effectively strengthen the structural strength of the door inner panel 10, thereby reducing the optimization of the strength of the door inner panel 10 in the later stage.

[0029] Wherein, the inner side of the door inner panel 10 is defined as the side of the door inner panel 10 facing the vehicle body, that is, facing the driver's seat of the vehicle. The outer side of the door inner panel 10 is defined as the side of the door inner panel 10 facing away from the vehicle body, that is, the side of the door inner panel 10 facing away from the driver's seat of the vehicle.

[0030] Wherein, when the door is closed, the first direction X is along the extension direction of the vehicle body, and the second direction Y can be any direction along the vehicle body, which can be set according to the setting position of the loudspeaker, which is not limited here.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 2 is a partial cross-sectional structure schematic view of an embodiment of the door inner panel of the present application; Figure 3Fig. 2 is a schematic view of a partial structure of an embodiment of the vehicle door inner panel according to the present application. In some embodiments of the present application, the body portion 112 further has an inner panel large surface 1121 formed thereon, which is located in the peripheral region of the second reinforcing cavity 114. The height difference H1 between the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located and the plane in which the inner panel large surface 1121 is located is 15-30 mm. The inner panel large surface 1121 can be used to mount some components of the vehicle and can also provide good support to the first reinforcing cavity 113 and the second reinforcing cavity 114. Therefore, by forming the inner panel large surface 1121 in the peripheral region of the second reinforcing cavity 114, the inner panel large surface 1121 can be used to mount the remaining components and has a strong structural strength, thereby facilitating the enhancement of the structural strength of the vehicle door inner panel 10.

[0032] Further, the height difference H1 between the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located and the plane in which the inner panel large surface 1121 is located is 15-30 mm. When the height difference H1 between the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located and the plane in which the inner panel large surface 1121 is located is less than 15 mm, the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located are close to the plane in which the inner panel large surface 1121 is located, and thus the reinforcing effect of the first reinforcing cavity 113 and the second reinforcing cavity 114 is poor, thereby affecting the overall structural strength of the vehicle door inner panel 10. When the height difference H1 between the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located and the plane in which the inner panel large surface 1121 is located is greater than 30 mm, the height difference H1 between the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located and the plane in which the inner panel large surface 1121 is located is too large, and thus the sheet metal is prone to breaking during the stamping of the first reinforcing cavity 113 and the second reinforcing cavity 114, thereby affecting the product quality and production efficiency of the vehicle door inner panel 10. Therefore, when the height difference H1 between the plane in which the bottom wall of the first reinforcing cavity 113 is located and the plane in which the bottom wall of the second reinforcing cavity 114 is located and the plane in which the inner panel large surface 1121 is located is 15-30 mm, the structural strength of the vehicle door inner panel 10 can be effectively improved, the sheet metal is not prone to breaking during the production process, and the product quality and production efficiency can be effectively improved.

[0033] The height difference between the plane where the bottom wall of the first reinforcing cavity 113 is located and the plane where the inner plate large surface 1121 is located and the height difference between the plane where the bottom wall of the second reinforcing cavity 114 is located and the plane where the inner plate large surface 1121 is located can be equal or not equal, as long as the height difference between the plane where the bottom wall of the first reinforcing cavity 113 is located and the plane where the inner plate large surface 1121 is located and the height difference between the plane where the bottom wall of the second reinforcing cavity 114 is located and the plane where the inner plate large surface 1121 is located are both within the range of 15mm-30mm. When the height difference between the plane where the bottom wall of the first reinforcing cavity 113 is located and the plane where the inner plate large surface 1121 is located is equal to the height difference between the plane where the bottom wall of the second reinforcing cavity 114 is located and the plane where the inner plate large surface 1121 is located, the design of the inner side of the door inner plate 10 is better, the aesthetic property is better, and the user experience is improved.

[0034] The height difference H1 between the plane where the bottom wall of the first reinforcing cavity 113 is located and the plane where the inner plate large surface 1121 is located and the plane where the bottom wall of the second reinforcing cavity 114 is located can be 15mm, 18mm, 20mm, 22mm, 24mm, 25mm, 27mm, 28mm, 28.5mm, 28.8mm, 29mm, 29.8mm, 30mm, etc., and can be set according to actual conditions, which will not be described here.

[0035] In some embodiments of the present application, the door inner plate 10 further comprises an inner plate sealing portion 12. The inner plate sealing portion 12 surrounds the outer periphery of the area composed of the window portion 111 and the body portion 112. At least part of the inner plate large surface 1121 is located between the inner plate sealing portion 12 and the second reinforcing cavity 114. In the present application, the structure of the inner plate sealing portion 12 can effectively prevent water and dust, and can also achieve sound insulation and heat insulation, thereby improving the overall performance of the vehicle and effectively improving the comfort of passengers. Since the installation area of the loudspeaker is protruded towards the inner side of the door inner plate 10 to form the second reinforcing cavity 114, the loudspeaker can be correspondingly arranged at least partially in the second reinforcing cavity 114. When at least part of the inner plate large surface 1121 is located between the inner plate sealing portion 12 and the second reinforcing cavity 114, the inner plate large surface 1121 can form a certain buffer between the inner plate sealing portion 12 and the second reinforcing cavity 114, so that the inner plate sealing portion 12 can more effectively block the interference of dust, rain and noise from the outside on the loudspeaker, thereby improving the service life of the loudspeaker and the user experience. In addition, the above-mentioned arrangement can also improve the ability of the door inner plate 10 to disperse and withstand pressure, thereby improving the structural strength of the door inner plate 10 and improving the stability and safety of the vehicle during driving.

[0036] In some embodiments of this application, the inner panel sealing portion 12 protrudes towards the inner side of the door inner panel 10 relative to the inner panel large surface 1121. With this arrangement, no planar structure is formed between the inner panel sealing portion 12 and the inner panel large surface 1121, thereby effectively enhancing the structural strength of the inner panel sealing portion 12 and improving the overall structural strength of the door inner panel 10.

[0037] In some embodiments of this application, in the first direction X, the width L1 of the large inner panel surface 1121 located between the second reinforcing cavity 114 and the inner panel sealing part 12 is 15mm-30mm. When the width L1 of the large inner panel surface 1121 located between the second reinforcing cavity 114 and the inner panel sealing part 12 is less than 15mm, the width L1 of the large inner panel surface 1121 between the second reinforcing cavity 114 and the inner panel sealing part 12 is small, which cannot provide a good buffering effect on the sealing performance of the inner panel sealing part 12, thereby affecting the overall sealing performance of the inner panel sealing part 12. Since the width of the inner door panel 10 in the first direction X is usually fixed, when the width L1 of the large inner panel surface 1121 located between the second reinforcing cavity 114 and the inner panel sealing part 12 is greater than 30mm, the large inner panel surface 1121 will occupy the setting space of the second reinforcing cavity 114 or the setting space of the inner panel sealing part 12. When the large inner panel surface 1121 occupies the space of the second reinforcing cavity 114, it affects the structural strength of the door inner panel 10. Conversely, when the large inner panel surface 1121 occupies the space of the inner panel sealing part 12, it affects the overall sealing performance of the door inner panel 10. Therefore, when the width L1 of the large inner panel surface 1121 located between the second reinforcing cavity 114 and the inner panel sealing part 12 is between 15mm and 30mm, the door inner panel 10 can not only have good structural strength but also good sealing performance.

[0038] The width L1 of the inner plate large surface 1121 located between the second reinforcing cavity 114 and the inner plate sealing part 12 can be 15mm, 16mm, 18mm, 18.5mm, 19mm, 20.9mm, 22mm, 24.6mm, 27mm, 28.3mm, 29mm, 30mm, etc., and there is no limitation here.

[0039] In some embodiments of the present application, the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is 4mm-8mm. When the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is less than 4mm, the plane between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is close to a plane structure, thereby affecting the structural strength of the inner plate sealing portion 12. When the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is greater than 8mm, the sheet metal is prone to cracking during stamping of the inner plate sealing portion 12, thereby affecting the production efficiency of the inner plate sealing portion 12. Therefore, when the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is 4mm-8mm, the inner plate sealing portion 12 not only has strong structural strength, but also is not prone to cracking during production, thereby effectively improving the production efficiency of the inner plate sealing portion 12.

[0040] In some embodiments of the present application, the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is 4mm-8mm. When the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is less than 4mm, the plane between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is close to a plane structure, thereby affecting the structural strength of the inner plate sealing portion 12. When the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is greater than 8mm, the sheet metal is prone to cracking during stamping of the inner plate sealing portion 12, thereby affecting the production efficiency of the inner plate sealing portion 12. Therefore, when the height difference H2 between the plane where the inner plate sealing portion 12 is located and the plane where the large surface 1121 of the inner plate is located is 4mm-8mm, the inner plate sealing portion 12 not only has strong structural strength, but also is not prone to cracking during production, thereby effectively improving the production efficiency of the inner plate sealing portion 12.

[0041] In some embodiments of the present application, the width L2 of the inner plate sealing portion 12 in the first direction X is 15mm-20mm. When the width L2 of the inner plate sealing portion 12 in the first direction X is less than 15mm, the width of the inner plate sealing portion 12 is small, and thus the sealing performance of the inner plate sealing portion 12 is reduced. However, since the size of the door inner plate 10 is fixed, when the width L2 of the inner plate sealing portion 12 in the first direction X is greater than 20mm, the width of the large surface 1121 of the inner plate or the second reinforcing cavity 114 is indirectly affected, thereby affecting the structural strength of the door inner plate 10. Therefore, when the width L2 of the inner plate sealing portion 12 in the first direction X is 15mm-20mm, the inner plate sealing portion 12 not only has good sealing performance, but also can ensure the structural strength of the door inner plate 10.

[0042] In some embodiments of the present application, the width L2 of the inner plate sealing portion 12 in the first direction X is 15mm-20mm. When the width L2 of the inner plate sealing portion 12 in the first direction X is less than 15mm, the width of the inner plate sealing portion 12 is small, and thus the sealing performance of the inner plate sealing portion 12 is reduced. However, since the size of the door inner plate 10 is fixed, when the width L2 of the inner plate sealing portion 12 in the first direction X is greater than 20mm, the width of the large surface 1121 of the inner plate or the second reinforcing cavity 114 is indirectly affected, thereby affecting the structural strength of the door inner plate 10. Therefore, when the width L2 of the inner plate sealing portion 12 in the first direction X is 15mm-20mm, the inner plate sealing portion 12 not only has good sealing performance, but also can ensure the structural strength of the door inner plate 10.

[0043] In some embodiments of the present application, in order to reduce the weight of the door inner panel 10, a plurality of weight-reducing holes 1122 are formed in the body portion 112 for reducing the weight of the door inner panel 10. The arrangement of the weight-reducing holes 1122 can effectively reduce the weight of the door inner panel 10, which is conducive to the lightweight design of the door inner panel 10.

[0044] Preferably, the second reinforcing cavity 114 is arranged close to the inner panel sealing portion 12, and the first reinforcing cavity 113 and the second reinforcing cavity 114 form an L-shaped cavity feature, so that the size of the weight-reducing hole 1122 can be as large as possible, thereby reducing the number of weight-reducing holes 1122. The above arrangement can not only effectively reduce the weight of the door inner panel 10 and facilitate the lightweight design of the door inner panel 10, but also reduce the waste generated during production, thereby saving production costs and improving production efficiency. In addition, the above arrangement can also increase the area of the inner panel large surface 1121 on the side of the second reinforcing cavity 114, thereby facilitating the installation and cooperation of other components.

[0045] In a second aspect of the present application, a vehicle is provided. The vehicle includes a vehicle body and any of the above-mentioned door inner panel 10. The door inner panel 10 is mounted on the vehicle body. Specifically, since the vehicle includes the door inner panel 10 described in the above embodiments, it also has the beneficial effects of the door inner panel 10 described above, which will not be repeated here.

[0046] In another embodiment of the present application, a speaker is arranged on the inner side of the door inner panel 10, wherein the speaker is arranged corresponding to at least part of the second reinforcing cavity 114. The above arrangement can optimize the sound level in the vehicle body and improve the user's experience. On the other hand, the side space of the door inner panel 10 is relatively spacious, which can facilitate the installation personnel to operate and adjust the position and angle of the speaker to improve the sound effect of the speaker. Moreover, the second reinforcing cavity 114 is arranged corresponding to the speaker, and the second reinforcing cavity 114 can also provide good covering effect for the speaker, thereby providing good protection for the speaker.
