Description

Technical Field

[0001] The utility model belongs to the technical field of door inner panels, and more specifically, relates to a door inner panel structure and a vehicle. Background Art

[0002] Applying carbon fiber composite materials to the automotive body structure can significantly reduce the body weight. However, carbon fiber composite materials and metals have completely different material and process forming characteristics. Therefore, for the design of carbon fiber bodies, it cannot be the same as metal structures, otherwise it will cause problems such as high process difficulty, high manufacturing cost, and inability to maximize the advantages of carbon fiber itself.

[0003] For the door structure, the door inner panel and the door outer panel of the traditional sheet metal door are connected by hemming, that is, the edge of the door outer panel is bent inward to form a hemming structure to fix the door inner panel. However, the carbon fiber composite material door cannot be connected by hemming and can only be connected by structural adhesive bonding. In order to ensure the firmness after bonding the door inner panel and the door outer panel, the width of the connecting flange of the door inner panel is usually set relatively large to increase the contact area with the door outer panel. Since the connecting flange is bent outward into the cavity between the door inner panel and the door outer panel, after the structural adhesive is coated on the connecting flange and the door outer panel, it is easy to overflow the cavity, which not only affects the overall appearance of the door, but also requires post-processing for the excessive overflow adhesive, increasing the production cost.

T

[0032] Please refer to together Figures 1 to 7 , and now the door inner panel structure and the vehicle provided by the present utility model will be described. The door inner panel structure includes an inner panel body 1 and a connecting flange 5. The inner panel body 1 is arranged on the inner side of the outer door panel 3, and the inner panel body 1 has a receiving groove 101 recessed inward; the connecting flange 5 is arranged at the end of the inner panel body 1, and the connecting flange 5 has a first connecting area 501 located in the receiving groove 101 and a second connecting area 502 located outside the receiving groove 101. Both the first connecting area 501 and the second connecting area 502 are used for connecting with the outer door panel 3.

[0033] The door inner panel structure provided by the present utility model, compared with the prior art, has the connecting flange 5 provided at the end of the inner panel body 1, and the connecting flange 5 extends into the receiving groove 101 to form a first connecting area 501 and extends out of the receiving groove 101 to form a second connecting area 502. When connecting the door inner panel structure to the door outer panel 3, structural adhesive is applied to the connecting flange 5, and the structural adhesive overflows into the receiving groove 101. The present utility model not only ensures the connection area between the connecting flange 5 and the door outer panel 3, increasing the firmness of the connection, but also has the first connecting area 501 disposed within the receiving groove 101. On the one hand, it can make both the inner and outer sides of the inner panel body 1 receive the adhesive force and be evenly stressed; on the other hand, it can achieve the overflow of the structural adhesive into the receiving groove 101 when the connecting flange 5 is bonded to the door inner panel, avoiding the problem in the prior art that the connecting flange 5 bends out of the receiving groove 101, resulting in the structural adhesive only overflowing out of the receiving groove 101 and requiring subsequent shaping of the overflowed structural adhesive.

[0034] Specifically, the middle part of the connecting flange 5 is connected to the inner panel body 1, so that the connecting flange 5 has a first connecting area 501 located within the receiving groove 101 and a second connecting area 502 located outside the receiving groove 101, and the connecting flange 5 and the inner panel body 1 form a "T" - shaped structure.

[0035] Optionally, the connecting flange 5 and the inner panel body 1 are integrally formed.

[0036] In some embodiments, please refer to Figures 2 to 4 , the inner panel body 1 has a hinge connection area 102, and the door inner panel structure further includes a hinge reinforcement plate 4 connected to the hinge connection area 102. The hinge connection area 102 protrudes into the receiving groove 101 to form a boss structure, increasing the thickness of the hinge connection area 102.

[0037] Since the hinge is installed on the hinge reinforcement plate 4 and the hinge reinforcement area, the hinge will vibrate when the door is closed. Therefore, higher strength requirements are imposed on the hinge reinforcement area on the door inner panel. In this embodiment, according to the characteristics of the carbon fiber material, the thickness of a local area of the inner panel body 1 is increased, so that the hinge connection area 102 protrudes into the receiving groove 101 to form a boss structure, increasing the thickness of the hinge connection area 102, thereby increasing the strength of the hinge connection area 102. The solution in this embodiment does not require increasing the overall thickness of the door inner panel, which is beneficial to the lightweight of the whole vehicle, and the boss structure protrudes into the receiving groove 101, avoiding occupying the interior space of the vehicle.

[0038] In some embodiments, please refer to Figures 4 to 6 , the door inner panel structure further includes a window frame reinforcement plate 2 connected to the inner side of the inner panel body 1. The window frame reinforcement plate 2 is a hollow tubular member and extends circumferentially along the window frame of the inner panel body 1 in a ring shape, and the window frame reinforcement plate 2 is also connected to the hinge reinforcement plate 4.

[0039] The window frame reinforcement plate 2 adopts a hollow tubular structure, so that it can have greater strength and stiffness even with a smaller cross-sectional size, meeting the requirements of the window frame position for the field of vision. In addition, the window frame reinforcement plate 2 is arranged around the outer periphery of the window frame of the inner plate body 1, improving the anti-deformation ability of the area near the window frame of the inner plate body 1.

[0040] Optionally, the upper part of the hinge reinforcement plate 4 is connected to the window frame reinforcement plate 2 and is located between the inner plate body 1 and the window frame reinforcement plate 2 in the inner and outer directions.

[0041] In some embodiments, please refer to Figures 4 to 6 , an installation flanging that bends outward is provided on the inner plate body 1, and the installation flanging is connected to the window frame reinforcement plate 2.

[0042] The installation flanging increases the connection area with the window frame reinforcement plate 2. The installation flanging is located on the inner circumferential wall of the annular structure formed by the window frame reinforcement plate 2. The installation flanging can be arranged in a complete circle along the inner circumferential wall or a part of it, facilitating the increase of the bonding area between the window frame reinforcement plate 2 and the inner plate body 1, meeting the bonding size requirements, and ensuring the connection strength of the structure.

[0043] In some embodiments, please refer to Figures 6 to 7 , the window frame reinforcement plate 2 includes an integrally formed lower bottom pipe 201, an upper top pipe 202, and a side vertical pipe 203. The installation flanging includes a lower flanging 103 connected to the top wall of the lower bottom pipe 201, and the top wall of the lower bottom pipe 201 extends obliquely upward and outward.

[0044] In this embodiment, the window frame reinforcement plate 2 adopts a structure in which the lower bottom pipe 201, the upper top pipe 202, and the side vertical pipe 203 are integrally formed. The above components can enclose polygons with different sizes, and corresponding sizes can be selected according to the vehicle model characteristics.

[0045] It should be noted that for the front door position of the vehicle, the upper top pipe 202 and the front side vertical pipe 203 can adopt an integrally formed structure with an arc-shaped extension. At this time, the window frame reinforcement plate 2 forms an approximately triangular frame structure.

[0046] Optionally, the lower flanging 103 of the inner plate body 1 extends toward the side away from the vehicle body central axis and is connected to the top wall of the lower bottom pipe 201. The top wall of the lower bottom pipe 201 extends obliquely upward and outward, facilitating the reduction of the bending angle of the lower flanging 103, realizing the effective bonding of the lower flanging 103 and the top wall of the lower bottom pipe 201, meeting the bonding size requirements, and improving the connection reliability.

[0047] In some embodiments, please refer to Figure 7 , the top wall of the upper top pipe 202 extends obliquely upward and outward, and the upper edge of the inner plate body 1 is provided with an upper flanging 104 connected to the top wall of the upper top pipe 202.

[0048] On the basis of connecting the lower flanging 103 to the top wall of the lower bottom pipe 201, an upper flanging 104 is further provided on the inner panel body 1, and the upper flanging 104 can be effectively bonded to the top wall of the upper top pipe 202, increasing the bonding area between the inner panel body 1 and the window frame reinforcing plate 2.

[0049] In some embodiments, refer to Figure 4 , a reinforcing bump 204 protruding outward is integrally formed on the window frame reinforcing plate 2. The reinforcing bump 204 is located at the front part of the window frame reinforcing plate 2, and the reinforcing bump 204 is horizontally corresponding to and connected with the outer rearview mirror mounting plate.

[0050] In this embodiment, for the window frame reinforcing plate 2 on the front door of the vehicle, a reinforcing bump 204 is further provided. The reinforcing bump 204 is located at a position of the window frame reinforcing plate 2 close to the outer rearview mirror, that is, at the outer front part of the window frame reinforcing plate 2. The reinforcing bump 204 protrudes outward, can be horizontally corresponding to the outer rearview mirror mounting plate 6, can realize the reliable installation of the outer rearview mirror mounting plate 6, ensure the connection strength of the structure, improve the structural strength of this part of the window frame, form a force transmission channel arranged along the outer rearview mirror reinforcing plate and the lower bottom pipe 201 and extending in the front-back direction, so that multiple force transmission channels from top to bottom and from front to back are formed in the window frame part, ensure the continuity of the vehicle window frame force transmission, enhance the stiffness of the front side corner part of the window frame and the outer rearview mirror mounting position, and improve the reliability of the structural installation.

[0051] In some embodiments, refer to Figure 6 , an extension part 205 connected to the inner panel body 1 is integrally formed on the front side of the window frame reinforcing plate 2. The extension part 205 is located on the side of the inner panel body 1 away from the vehicle body central axis.

[0052] In this embodiment, the extension part 205 is connected to the front side of the window frame reinforcing plate 2, and this structure is suitable for the window frame reinforcing plate 2 of the vehicle rear door. The extension part 205 can be reliably connected to the side wall of the inner panel body 1, further enhancing the self-structural strength of the window frame reinforcing plate 2, and at the same time increasing the connection area between the window frame reinforcing plate 2 and the inner panel body 1, ensuring the reliability of the structural connection.

[0053] Based on the same inventive concept, the present utility model further provides a vehicle. Refer to Figure 1 , the vehicle includes the above-mentioned door inner panel structure, and further includes an outer door panel 3 arranged outside the door inner panel structure and connected to the connecting flanging 5.

[0054] The vehicle provided by the present utility model adopts the above-mentioned inner door panel structure. The connecting flange 5 is arranged at the end of the inner panel body 1, and the connecting flange 5 extends into the receiving groove 101 to form a first connecting area 501 and extends out of the receiving groove 101 to form a second connecting area 502. When connecting the inner door panel structure to the outer door panel 3, structural adhesive is applied to the connecting flange 5, and the structural adhesive overflows into the receiving groove 101. The present utility model not only ensures the connection area between the connecting flange 5 and the outer door panel 3, increasing the firmness of the connection, but also arranges the first connecting area 501 in the receiving groove 101. On the one hand, both the inner and outer sides of the inner panel body 1 can be subjected to the adhesive force, and the force is uniform; on the other hand, when the connecting flange 5 is bonded to the inner door panel, the structural adhesive can overflow into the receiving groove 101, avoiding the problem in the prior art that the connecting flange 5 bends out of the receiving groove 101, resulting in the structural adhesive only overflowing out of the receiving groove 101 and requiring subsequent shaping of the overflowed structural adhesive, thus saving production man-hours and costs.

[0055] In some embodiments, please refer to Figure 8 , the edge of the outer door panel 3 has a limiting portion 301 protruding inward, and the limiting portion 301 is located on the outer periphery of the second connecting area 502.

[0056] By arranging a limiting portion 301 protruding inward at the edge of the outer door panel 3, after the connecting flange 5 is connected to the outer door panel 3, the outer edge of the second connecting area 502 is located inside the inner periphery of the limiting portion 301. Even if the structural adhesive overflows out of the second connecting area 502, it can be blocked by the limiting portion 301, making the connection between the outer door panel 3 and the connecting flange 5 smooth and without subsequent shaping.

[0057] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
