[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 9 A vehicle door inner panel according to an embodiment of the present utility model is described.

[0032] In the related art, reinforcing components such as reinforcing rods or support rods are usually provided on the inner door panel. However, the method of adding reinforcing components increases the weight of the inner door panel, making it difficult to meet the goal of lightweight door structure. In addition, the method of adding reinforcing components cannot effectively disperse the impact force, resulting in the area of ​​the inner door panel with reinforcing components having higher strength, while the area without reinforcing components has lower strength, resulting in uneven strength of the inner door panel.

[0033] Therefore, the utility model proposes a vehicle door inner panel to solve the above-mentioned technical problems.

[0034] like Figure 1 and Figure 3 As shown, the door inner panel includes: an inner panel body 1 and a first reinforcing rib 2. The first reinforcing rib 2 is arranged around the stop position of the inner panel body 1 near the four edges. The first reinforcing rib 2 protrudes toward the inner side of the vehicle and forms a closed annular protrusion structure on the inner wall of the inner panel body 1.

[0035] In this way, the first reinforcing rib 2 is arranged around the stop positions around the inner panel body 1 and protrudes toward the inner side of the vehicle, providing the inner panel body 1 with a full circle of "closed-loop force channel", so that the overall force distribution of the door inner panel can be dispersed at different positions, ensuring that the overall structure of the door inner panel is more evenly stressed.

[0036] In some embodiments, a third installation area 105 , a fourth installation area 106 , a fifth installation area 107 , a sixth installation area 108 , a seventh installation area 109 , an eighth installation area 110 , and a ninth installation area 111 are provided at the stop positions around the inner panel body 1 . Among them, the third installation area 105 is the inner water cut installation sill area, that is, the installation position of the water cut; the fourth installation area 106 is the hinge structure installation structure area, that is, the installation position of the door hinge, belongs to the front area of ​​the door inner panel, is located on one side of the limiter, and together with the limiter installation structure area, constitutes the front area of ​​the door inner panel; the fifth installation area 107 is the limit installation structure area, that is, the installation position of the door limiter, and belongs to the front area of ​​the door inner panel; the sixth installation area 108 is the front corner area of ​​the door sill, that is, the transition area connecting the door hinge structure installation structure area and the door sill crossbeam structure area; the seventh installation area 109 is the sill crossbeam structure area, that is, the main force channel of the lower part of the vehicle body, and is the arrangement position of the sill beam; the eighth installation area 110 is the rear corner area of ​​the door sill, that is, the transition area connecting the door lock installation structure area and the door sill crossbeam structure area; the ninth installation area 111 is the door lock installation structure area, that is, the installation position of the door lock body.

[0037] The third installation area 105, the fourth installation area 106, the fifth installation area 107, the sixth installation area 108, the seventh installation area 109, the eighth installation area 110, and the ninth installation area 111 are connected in a clockwise direction. A first annular reinforcing rib 2 is provided in the above-mentioned installation areas to strengthen the strength of multiple installation areas, so that the force on the vehicle door forms a complete closed loop, and the overall force is uniform. At the same time, the connection strength between the hinge structure installation structure and the limit installation structure on the vehicle door inner panel and the vehicle door inner panel is improved.

[0038] Therefore, the first reinforcing rib 2 is arranged around the stopper position around the inner panel body 1, so that the force of the door forms a complete closed loop, and the overall force distribution of the door inner panel can be dispersed at different positions, ensuring that the overall structure of the door inner panel is more evenly stressed. In addition, the first reinforcing rib 2 is arranged at the stopper boundary to ensure the peripheral stiffness of the door to avoid force vibration, thereby ensuring good NVH performance when the door is opened and closed.

[0039] According to some specific embodiments of the present invention, see Figure 4 and Figure 5 As shown, the cross-sectional shape of the first reinforcing rib 2 includes: a first main rib portion 201 and a first side rib portion 202, the first side rib portion 202 is respectively connected to both sides of the first main rib portion 201, the first side rib portion 202 is bent and extended toward the outside of the vehicle relative to the first main rib portion 201, and is connected to the inner wall of the inner panel body.

[0040] With such arrangement, the cross-sectional shape of the first reinforcing rib 2 is an arch structure. By utilizing the high strength of the arch structure, the strength of the stop positions around the inner panel body 1 can be increased, so that the overall force distribution of the door inner panel can be dispersed at different positions, ensuring that the overall structure of the door inner panel is more evenly stressed.

[0041] According to some specific embodiments of the present invention, see Figure 2 and Figure 3 As shown, a first through hole 101 is provided on the side of the inner panel body 1 away from the vehicle body. The door inner panel further comprises: a second reinforcing rib 3, which is provided around at least part of the periphery of the first through hole 101 and protrudes toward the inner side of the vehicle.

[0042] That is to say, the inner panel body 1 is provided with a first through hole 101 on one side close to the ninth installation area 111, and the first through hole 101 can be used as a process through hole for installing internal door accessories. Since internal door accessories need to be installed here, the present application strengthens this place, that is, a second reinforcing rib 3 is provided around at least part of the outer periphery of the first through hole 101, so that at least part of the first through hole 101 forms an island-shaped reinforcement structure, thereby improving the strength and rigidity of the first through hole 101, thereby ensuring the installation firmness of the internal door accessories.

[0043] Some specific embodiments, see Figure 4 and Figure 6 As shown, the cross-sectional shape of the second reinforcing rib 3 includes: a second main rib portion 301 and a second side rib portion 302, the second side rib portions 302 are respectively connected to the two sides of the second main rib portion 301, the second side rib portion 302 is bent and extended toward the outside of the vehicle relative to the second main rib portion 301, the second side rib portion 302 away from the first through hole 101 is connected to the inner wall of the inner panel body, and the second side rib portion 302 adjacent to the first through hole 101 is provided with a flange 303.

[0044] With such arrangement, the cross-sectional shape of the second reinforcing rib 3 is an arch structure. By utilizing the high strength of the arch structure, the strength and rigidity at the first through hole 101 can be improved, and the second side rib portion 302 adjacent to the first through hole 101 is provided with a flange 303 to facilitate operation and improve the connection reliability of the door inner panel accessories.

[0045] According to some specific embodiments of the present invention, see Figure 2 and Figure 3 As shown, a second through hole 102 is provided on the side of the inner panel body 1 adjacent to the vehicle body, and the second through hole 102 is provided at the lower part of the inner panel body 1. The door inner panel also includes: a third reinforcing rib 4, which is provided around at least part of the outer periphery of the second through hole 102 and protrudes toward the inner side of the vehicle.

[0046] That is, a second through hole 102 is provided on one side of the inner panel body 1 close to the fourth installation area 106 / fifth installation area 107. The second through hole 102 can be used as a layout area for the accessory speaker inside the door, and is located at the lower part of the inner panel of the door. Since the accessory speaker needs to be installed here, the present application strengthens this place, that is, a third reinforcing rib 4 is provided around at least part of the outer periphery of the second through hole 102, so that at least part of the second through hole 102 forms an island-shaped reinforcement structure, thereby improving the strength and rigidity of the second through hole 102, thereby ensuring the installation firmness of the accessory speaker inside the door.

[0047] Some specific embodiments, see Figure 4 and Figure 7 As shown, the cross-sectional shape of the third reinforcing rib 4 includes a third main rib portion 401 and a third side rib portion 402, the third side rib portions 402 are respectively connected to both sides of the third main rib portion 401, the third side rib portion 402 away from the second through hole 102 is bent and extended toward the outside of the vehicle relative to the third main rib portion 401, and is connected to the inner wall of the inner panel body, and the third side rib portion 402 adjacent to the second through hole 102 is bent and arranged toward the outside of the vehicle relative to the third main rib portion 401.

[0048] In this way, the cross-section of the third reinforcing rib 4 is an arched structure, and the strength and rigidity of the second via hole 102 can be improved by utilizing the arched structure's high strength. In addition, the third side rib portion 402 adjacent to the second via hole 102 is bent toward the outside of the vehicle relative to the third main rib portion 401, which will not cause interference with the installation of the speaker.

[0049] According to some specific embodiments of the present invention, see Figure 2 and Figure 3 As shown, a first mounting area 103 is provided on a side of the inner panel body 1 adjacent to the vehicle body, and the first mounting area 103 is provided at an upper portion of the inner panel body 1. The door inner panel further includes a fourth reinforcing rib 5, which is provided around at least a portion of the periphery of the first mounting area 103 and protrudes toward a side inside the vehicle.

[0050] In this way, the first installation area 103 can be used as the main arrangement area of ​​the accessory controller inside the door, and is located at the upper part of the inner panel body 1. Since the accessory controller needs to be installed here, the present application strengthens this place, that is, the fourth reinforcing rib 5 is arranged around at least part of the outer periphery of the first installation area 103, so that at least part of the first installation area 103 forms an island-shaped reinforcement structure, which improves the strength and rigidity of the first installation area 103, thereby ensuring the installation firmness of the accessory controller inside the door.

[0051] Some specific embodiments, see Figure 8As shown, the cross-sectional shape of the fourth reinforcing rib 5 includes a fourth main rib portion 501 and a fourth side rib portion 502. The fourth side rib portion 502 is respectively connected to both sides of the fourth main rib portion 501. The fourth side rib portion 502 is bent and extended toward the vehicle outer side relative to the fourth main rib portion 501, and is connected to the inner wall of the inner panel body. In this way, the cross-sectional shape of the fourth reinforcing rib 5 is an arched structure. By utilizing the high strength of the arched structure, the strength and rigidity of the first installation area 103 can be improved.

[0052] Therefore, see Figure 3 By locally reinforcing the installation structure area of ​​the accessory speakers, controllers, etc. inside the door, three island structures are formed on the inner panel body 1, one is located on the side of the inner panel body 1 away from the connection with the vehicle body, and the other two are located on the side of the inner panel body 1 adjacent to the connection with the vehicle body. That is, the three island structures are arranged at the position where the inner panel of the door is subjected to greater force, which can ensure the strength and rigidity of the position where the inner panel is subjected to greater force.

[0053] According to some specific embodiments of the present invention, see Figure 2 and Figure 3 As shown, a second mounting area 104 is provided in the middle of the inner panel body 1, and the second mounting area 104 is extended along the inclination direction of the rear side column of the door inner panel. The door inner panel also includes a fifth reinforcing rib 6, which is provided through the second mounting area 104 and protrudes toward the inner side of the vehicle.

[0054] In this way, the second installation area 104 can be used as the main arrangement area of ​​the door interior accessory window lifter. In addition, the second installation area 104 is extended along the inclination direction of the rear side column of the door inner panel. For example, when the door inner panel is the front vehicle interior panel, the second installation area 104 is extended along the inclination direction of the B-pillar of the door inner panel.

[0055] Since this place is mainly responsible for installing the glass lifter, the present application strengthens this place, that is, a fifth reinforcing rib 6 is set in the second installation area 104, and the whole is penetrated through the second installation area 104 to form a reinforcing rib structure in the height direction, so as to improve the strength and rigidity of the second installation area 104, thereby ensuring the installation firmness of the glass lifter.

[0056] See Figure 4 and Fig. 9 As shown, the cross-sectional shape of the fifth reinforcing rib 6 includes: a fifth main rib portion 601 and a fifth side rib portion 602. The fifth side rib portion 602 is respectively connected to both sides of the fifth main rib portion 601 and is connected to the inner wall of the inner panel body. At least one groove 603 is provided on the fifth main rib portion 601, and the groove 603 is recessed toward the outside of the vehicle.

[0057] In this way, the cross-sectional shape of the fifth reinforcing rib 6 is an arched structure, and the arched structure has the characteristic of high strength, which can improve the strength and rigidity of the second installation area 104. In addition, at least one groove 603 is provided on the fifth main rib portion 601, which can improve the strength and rigidity of the fifth reinforcing rib 6, and further improve the strength and rigidity of the second installation area 104.

[0059] In this way, a sixth reinforcing rib 7 is provided on one side of the front side column of the door inner panel adjacent to the second installation area 104, so that the sixth reinforcing rib 7 is roughly arranged in the middle area of ​​the inner panel body, and the sixth reinforcing rib 7 is extended along the inclination angle of the rear side column of the door inner panel as a whole, so that the inner panel body 1 has an integral reinforcing rib structure penetrating in the height direction. The penetrating reinforcing rib structure can ensure the complete rigidity of the door inner panel itself, and avoid bending modal vibration caused by insufficient rigidity in other directions.

[0060] In some specific embodiments, the cross-sectional shape of the sixth reinforcing rib 7 includes: a sixth main rib portion and a sixth side rib portion, wherein the sixth side rib portion is respectively connected to both sides of the sixth main rib portion and is connected to the inner wall of the inner panel body. In this way, the cross-sectional shape of the sixth reinforcing rib 7 is an arch structure, and the arch structure has the characteristic of high strength, so as to improve the strength and rigidity of the middle area of ​​the door inner panel, and avoid bending mode vibration caused by insufficient rigidity in other directions.

[0061] A vehicle according to an embodiment of the second aspect of the utility model includes a door inner panel.

[0062] Therefore, the door inner panel according to the utility model has the following effects:

[0063] First, the first reinforcing rib 2 is arranged around the stopper position around the inner panel body 1, so that the force of the door forms a complete closed loop, so that the overall force distribution of the door inner panel can be dispersed at different positions, ensuring that the overall structure of the door inner panel is more evenly stressed. In addition, the first reinforcing rib 2 is arranged at the stopper boundary to ensure the rigidity of the door periphery to avoid force vibration, thereby ensuring good NVH performance when the door is opened and closed.

[0064] Secondly, by respectively setting the second reinforcing rib 3, the third reinforcing rib 4 and the fourth reinforcing rib 5 in the mounting structure areas of the internal door accessory speakers, controllers, etc., the internal door accessory mounting structure is locally reinforced, and three island structures are formed on the inner panel body 1, one is located on the side of the inner panel body 1 away from the connection with the vehicle body, and the other two are located on the side of the inner panel body 1 adjacent to the connection with the vehicle body, that is, the three island structures are arranged at the position where the inner panel of the vehicle door is subjected to greater force, which can ensure the strength and rigidity of the position where the local force of the inner panel of the vehicle is greater.

[0065] Third, by arranging the fifth reinforcing rib 6 and the sixth reinforcing rib 7 in the second installation area 104 and its vicinity in the middle of the inner panel body 1, the inner panel body 1 has two integral reinforcing rib structures penetrating in the height direction. The penetrating reinforcing rib structure can ensure the full rigidity of the door inner panel itself and avoid bending modal vibration caused by insufficient rigidity in other directions. The fifth reinforcing rib 6 can also ensure the installation firmness of the window lifter.
