Description

Technical Field

[0001] This application relates to the field of automotive technology, specifically to a door structure and a vehicle. Background Technology

[0002] Currently, traditional automotive door handle designs typically require fastening points at both ends of the handle, relying on independent sheet metal brackets to connect it to the inner door panel. However, the independent manufacturing of these brackets consumes additional materials (such as SECC steel), and their stamping and welding processes increase processing costs and assembly complexity. Furthermore, the added weight of the brackets (typically 200-400g) is detrimental to the overall vehicle lightweight design. Therefore, there is an urgent need for a door structure that can reliably fix the handle to the inner door panel without relying on sheet metal brackets, thereby reducing manufacturing costs and simplifying the assembly process. Utility Model Content

[0003] In view of the above, it is necessary to propose a door structure and vehicle to reduce manufacturing costs and simplify the assembly process while achieving reliable fixation between the handle and the inner side panel of the door.

[0004] This application provides a vehicle door structure, including an inner door panel, an inward-opening handle base, a door panel body, a center trim panel, a handle base, and a handle. The inward-opening handle base is located on one side of the inner door panel and connected to it. The door panel body is located on the side of the inward-opening handle base opposite to the inner door panel and connected to it. The center trim panel is located on the side of the door panel body opposite to the inward-opening handle base and connected to it. The handle base and the handle are both located on the side of the center trim panel opposite to the door panel body. One end of the handle base passes through the center trim panel and is connected to the door panel body. The handle is connected to one side of the handle base.

[0005] The door structure of this application embodiment directly fixes the inward-opening handle base to the inner side panel of the door, and sequentially stacks and fixes the door panel body and the middle trim panel. Simultaneously, one end of the handle base passes through the middle trim panel and connects to the door panel body, thus achieving an indirect and reliable fixation between the handle and the inner side panel of the door. This design eliminates the independent structure of the traditional sheet metal bracket. Through the integrated connection of the inner side panel of the door, the inward-opening handle base, and the door panel body, it can effectively control the appearance matching gap and surface difference while reducing costs. This not only reduces the number of parts and lowers material and processing costs, but also simplifies the assembly process; at the same time, it reduces the weight of the sheet metal bracket, improving the overall vehicle lightweighting level.

[0006] In some possible embodiments, the door structure further includes a first fastening structure, which is disposed at corresponding positions of the inward-opening handle base and the inner side panel of the door, and is respectively connected to the inward-opening handle base and the inner side panel of the door.

[0007] In some possible embodiments, the door structure further includes a second fastening structure, which is disposed at corresponding positions of the handle base, the door panel body, and the inward-opening handle base, and is respectively connected to the inward-opening handle base, the door panel body, and the inward-opening handle base.

[0008] In some possible embodiments, the handle base includes a mounting portion and an abutment portion. The mounting portion passes through the door panel body and the inward-opening handle base, and the abutment portion is located on the side of the mounting portion and abuts against the door panel body. The second fastening structure is connected to the handle base and the mounting portion respectively.

[0009] In some possible embodiments, the handle base further includes a first limiting portion located on one side of the mounting portion and passing through the door panel body and the inward-opening handle base.

[0010] In some possible embodiments, the handle includes a second limiting part, a supporting part, and a fixing part. The second limiting part passes through the handle base and is disposed near the first limiting part. The supporting part is located on one side of the second limiting part and supports the handle base. The fixing part is disposed on the handle base and connected to the supporting part.

[0011] In some possible embodiments, the handle base further includes a recess facing the interior of the handle, and the handle further includes an insertion portion adapted to the recess, the insertion portion being inserted into the recess.

[0012] In some possible embodiments, the door structure further includes a third fastening structure, which is disposed at corresponding positions of the center trim panel, the door panel body, and the inward-opening handle base, and is respectively connected to the center trim panel, the door panel body, and the inward-opening handle base.

[0013] In some possible embodiments, the door structure further includes a fourth fastening structure, which is disposed at corresponding positions on the door panel body and the inner side panel of the door, and is connected to the door panel body and the inner side panel of the door respectively.

[0014] This application also provides a vehicle including the door structure described in any of the above technical solutions.

[0015] In this embodiment, the vehicle achieves indirect and reliable fixing of the handle to the inner door panel by directly fixing the inward-opening handle base to the inner door panel, and sequentially stacking and fixing the door panel body and the center trim panel. Simultaneously, one end of the handle base passes through the center trim panel and connects to the door panel body, thus realizing indirect and reliable fixing of the handle to the inner door panel. This design eliminates the independent structure of traditional sheet metal brackets. Through the integrated connection of the inner door panel, the inward-opening handle base, and the door panel body, it not only reduces the number of parts and lowers material and processing costs but also simplifies the assembly process. Furthermore, it reduces the weight of the sheet metal brackets, improving the overall vehicle lightweighting level. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0029] Please see Figure 1 and Figure 2 This application provides a door structure 100, including an inner door panel 10, an inward-opening handle base 20, a door panel body 30, a center trim panel 40, a handle base 50, and a handle 60.

[0030] The inner door handle base 20 is located on one side of the inner door panel 10 and connected to the inner door panel 10. The door panel body 30 is located on the side of the inner door handle base 20 away from the inner door panel 10 and connected to the inner door handle base 20. The center trim panel 40 is located on the side of the door panel body 30 away from the inner door handle base 20 and connected to the door panel body 30. The handle base 50 and the handle 60 are both located on the side of the center trim panel 40 away from the door panel body 30. One end of the handle base 50 passes through the center trim panel 40 and is connected to the door panel body 30. The handle 60 is connected to one side of the handle base 50.

[0031] The door structure 100 of this application embodiment directly fixes the inward-opening handle base 20 to the inner side panel 10 of the door, and sequentially stacks and fixes the door panel body 30 and the middle trim panel 40. At the same time, one end of the handle base 50 passes through the middle trim panel 40 and connects to the door panel body 30, thereby achieving an indirect and reliable fixation between the handle 60 and the inner side panel 10 of the door. This design eliminates the independent structure of the traditional sheet metal bracket. Through the integrated connection of the inner side panel 10 of the door, the inward-opening handle base 20 and the door panel body 30, it can effectively control the appearance matching gap and surface difference while reducing costs. It not only reduces the number of parts and lowers material and processing costs, but also simplifies the assembly process. At the same time, it reduces the weight of the sheet metal bracket and improves the overall vehicle lightweighting level.

[0032] Please see also Figure 3 In some possible embodiments, the door structure 100 further includes a first fastening structure 70, which is disposed at corresponding positions on the inward-opening handle base 20 and the inner door panel 10, and is connected to both the inward-opening handle base 20 and the inner door panel 10. By adding the first fastening structure 70 to connect the inward-opening handle base 20 and the inner door panel 10, the fixing strength and stability between the two are enhanced. At the same time, the setting of the first fastening structure 70 optimizes the load transmission path, so that the external force when the handle 60 is operated can be more evenly distributed to the inner door panel 10, thereby reducing local stress concentration, improving the overall structural durability, and further avoiding loosening or abnormal noise problems caused by long-term use.

[0033] The first fastening structure 70 includes a first fastener 71 and a first locking member 72. The first fastener 71 is located on the inner side panel 10 of the door, and the first locking member 72 is located on the inward-opening handle base 20 and connected to the first fastener 71. The first fastener 71 and the first locking member 72 cooperate to connect the inward-opening handle base 20 and the inner side panel 10 of the door. Specifically, the first fastener 71 is a closed-fit plastic nut, and the first locking member 72 is a screw.

[0034] Please see also Figure 4 and Figure 5In some possible embodiments, the door structure 100 further includes a second fastening structure 80. The second fastening structure 80 is disposed at corresponding positions on the handle base 50, the door panel body 30, and the inward-opening handle base 20, and is connected to the handle base 50, the door panel body 30, and the inward-opening handle base 20 respectively. By adding the second fastening structure 80 to connect the handle base 50, the door panel body 30, and the inward-opening handle base 20, the force transmission path of the handle 60 is further optimized, allowing the door panel body 30 and the inward-opening handle base 20 to jointly bear the load during the operation of the handle 60, thereby improving the rigidity and stability of the overall structure. At the same time, this multi-point fixing method can effectively disperse local stress and prevent structural deformation or loosening of connections due to long-term use. Specifically, the second fastening structure 80 is a screw, and the number of second fastening structures 80 can be multiple, such as three, but is not limited to this.

[0035] The door panel body 30 is recessed with a receiving groove 31 facing away from the middle trim panel 40. The receiving groove 31 is set in relation to the second fastening structure 80. The middle trim panel 40 is provided with a clearance hole 41 at the position corresponding to the receiving groove 31. One end of the handle base 50 passes through the clearance hole 41 of the middle trim panel 40 and abuts against the bottom of the receiving groove 31.

[0036] Please see also Figure 6 and Figure 7 In some possible embodiments, the handle base 50 includes a base body 51, a mounting part 52, and an abutment part 53. The base body 51 is located on the side of the middle trim panel 40 away from the door panel body 30. The mounting part 52 is generally columnar and is connected to one end of the base body 51. The mounting part 52 passes through the door panel body 30 and the inward-opening handle base 20. The abutment part 53 is sheet-like and is located on the side of the mounting part 52 and abuts against the door panel body 30. There are multiple abutment parts 53 and they are located on the outer periphery of the mounting part 52. The second fastening structure 80 is connected to the inward-opening handle base 20 and the mounting part 52 respectively. By having the mounting part 52 penetrate through the door panel body 30 and the inward-opening handle base 20 to form a mechanical interlock, and the abutment part 53 directly contacting the door panel body 30 to form a support surface, combined with the fixing effect of the second fastening structure 80, multi-level force transmission and more uniform load distribution are achieved, enhancing the torsional resistance and installation stability of the handle base 50. Specifically, both the mounting part 52 and the abutment part 53 are located within the receiving groove 31, with the abutment part 53 abutting against the bottom of the receiving groove 31.

[0037] In some possible embodiments, the handle base 50 further includes a first limiting part 54, which is a columnar structure. The first limiting part 54 is located on one side of the mounting part 52 and connected to the base body 51. The first limiting part 54 passes through the door panel body 30 and the inward-opening handle base 20. By adding the first limiting part 54 to the handle base 50, which passes through the door panel body 30 and the inward-opening handle base 20, the installation positioning accuracy of the handle base 50 is further enhanced, preventing offset or misalignment during assembly. At the same time, an additional mechanical limiting structure is formed, effectively suppressing radial movement and rotational loosening of the handle 60 during dynamic use.

[0038] In some possible embodiments, the handle 60 includes a handle body 61 and a second limiting part 62, a supporting part 63, and a fixing part 64, each disposed at one end of the handle body 61. The handle body 61 is disposed on one side of the base body 51 and connected to the base body 51. The second limiting part 62 is a columnar structure, passing through the handle base 50 and disposed close to the first limiting part 54. The supporting part 63 is located on one side of the second limiting part 62 and supports the handle base 50. The fixing part 64 is disposed on the handle base 50 and connected to the supporting part 63. By making the second limiting part 62 and the first limiting part 54 of the handle base 50 complement each other, the handle 60's degrees of freedom in multiple directions are effectively constrained. At the same time, the close contact between the supporting part 63 and the handle base 50 provides a stable support surface. Combined with the rigid connection of the fixing part 64, the handle 60 can evenly transmit the load to the base structure when subjected to tensile force.

[0039] In some possible embodiments, the handle base 50 further includes a recess 55, which is disposed facing the interior of the handle 60. The handle 60 also includes an insertion portion 65 adapted to the recess 55, which is inserted into the recess 55. By providing a recess 55 in the handle base 50 and correspondingly designing an insertion portion 65 on the handle 60, a plug-in mating structure is formed between the two. This not only achieves rapid positioning guidance during handle 60 installation, ensuring assembly accuracy and consistency, but also adds additional shear and torsional resistance to the original fastening connection through the interlocking structure. Specifically, there are two rows of recesses 55, with multiple recesses 55 in each row; the number of insertion portions 65 is equal to the number of recesses 55.

[0040] Please see also Figure 8In some possible embodiments, the door structure 100 further includes a third fastening structure 90, which is disposed at corresponding positions on the center trim panel 40, the door panel body 30, and the inner handle base 20, and is connected to the center trim panel 40, the door panel body 30, and the inner handle base 20 respectively. By adding the third fastening structure 90 to rigidly connect the center trim panel 40, the door panel body 30, and the inner handle base 20, a multi-layer composite fixing system is formed, which can effectively constrain the relative displacement between the components of each layer, and significantly improve the integrity and deformation resistance of the door panel assembly under dynamic working conditions. Specifically, the third fastening structure 90 is a screw.

[0041] Please see also Figure 9 In some possible embodiments, the door structure 100 further includes a fourth fastening structure 101. The fourth fastening structure 101 is located at corresponding positions on the door panel body 30 and the inner door panel 10, and is connected to both the door panel body 30 and the inner door panel 10. By adding the fourth fastening structure 101 to directly connect the door panel body 30 to the inner door panel 10, the overall rigidity of the inner and outer structures of the door is further enhanced, allowing the door panel body 30 to not only be indirectly connected via the inward-opening handle base 20, but also to form a direct mechanical transmission path with the inner door panel 10. Specifically, the fourth fastening structure 101 is a screw or a clip.

[0042] This application also provides a vehicle (not shown), including a vehicle body and the aforementioned door structure 100.

[0043] In this embodiment, the vehicle achieves indirect and reliable fixing of the handle 60 to the inner door panel 10 by directly fixing the inward-opening handle base 20 to the inner door panel 10, and by sequentially stacking and fixing the door panel body 30 and the center trim panel 40, while simultaneously connecting one end of the handle base 50 through the center trim panel 40 to the door panel body 30. This design eliminates the independent structure of the traditional sheet metal bracket. Through the integrated connection of the inner door panel 10, the inward-opening handle base 20, and the door panel body 30, cost reduction can be achieved while effectively controlling the appearance matching gap and surface difference. This not only reduces the number of parts and lowers material and processing costs, but also simplifies the assembly process; at the same time, it reduces the weight of the sheet metal bracket and improves the overall vehicle lightweighting level.
