[0026] The beneficial effects of this utility model are:

[0027] This utility model provides a connecting structure. When assembling the door assembly, firstly, the door lock is installed at the door lock mounting position of the connecting structure, with the part of the door lock that locks to the vehicle body extending out of the first clearance hole of the door lock. Then, the receiving groove portion of the connecting structure is inserted into the inner door panel, so that the first mounting surface of the inner door panel can connect with the inner door panel. The outer door panel support portion is located on the outer side of the inner door panel along the first orientation, and the part of the door lock that locks to the vehicle body extends out of the inner door panel. Then, the connecting portion is fixed to the inner door panel through the first mounting surface of the inner door panel. After the connecting portion is fixed to the inner door panel, the relative position of the connecting structure and the inner door panel is fixed. Then, the outer door panel is supported on the outer door panel support portion, and the relative position of the outer door panel and the inner door panel is fixed. In this way, the assembly of the door lock is completed, and the relative position of the inner door panel and the outer door panel is fixed.

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0062] In current technologies, to reduce the processing difficulty of the tailgate inner panel and improve the flexibility of tailgate lock arrangement, a reinforcing plate is usually used as a connecting structure to fix the tailgate lock to the tailgate inner panel. Although this can effectively reduce the stamping depth of the tailgate inner panel and improve the flexibility of tailgate lock arrangement, an additional independent support frame is still required to support the tailgate outer panel, resulting in a complex tailgate assembly structure, a large number of parts, and low production and disassembly efficiency.

[0063] like Figure 1-5 As shown, this utility model provides a connecting structure 1, which includes a connecting part 11 and an outer door panel support part 12. The connecting part 11 has a recessed receiving groove 111 along its first end face in a first orientation, and a second end face along the first orientation includes a first mounting surface 112 for the inner door panel. The groove wall of the receiving groove 111 has a door lock mounting position, and the door lock mounting position has a through door lock first clearance hole 113. The outer door panel support part 12 is connected to the connecting part 11. Along the first orientation, the second end face of the outer door panel support part 12 is farther away from the first end face from the connecting part 11.

[0064] Taking the application of the connecting structure 1 to a door assembly, which includes an inner door panel 2 and an outer door panel 3, as an example: When assembling the door assembly, first install the door lock at the door lock mounting position of the connecting structure 1, and make the part of the door lock that locks with the vehicle body extend out of the first clearance hole 113 of the door lock; or, after fixing the connecting structure 1 to the inner door panel 2, install the door lock at the door lock mounting position of the connecting structure 1, and make the part of the door lock that locks with the vehicle body extend out of the first clearance hole 113 of the door lock and the inner door panel 2.

[0065] Taking the installation of the door lock in the door lock mounting position of the connecting structure 1 as an example. When assembling the door assembly, first install the door lock in the door lock mounting position of the connecting structure 1, and make the part of the door lock that locks with the vehicle body extend out of the first clearance hole 113 of the door lock; then insert the part of the receiving groove 111 on the connecting structure 1 into the inner door panel 2, so that the first mounting surface 112 of the inner door panel can be connected to the inner door panel 2, and the outer door panel support part 12 is located on the side of the inner door panel 2 near the outside along the first orientation, and the part of the door lock that locks with the vehicle body extends out of the inner door panel 2; then fix the connecting part 11 to the inner door panel 2 through the first mounting surface 112 of the inner door panel. It can be understood that after the connecting part 11 is fixed to the inner door panel 2, the relative position of the connecting structure 1 and the inner door panel 2 is fixed; then support the outer door panel 3 on the outer door panel support part 12, and fix the relative position of the outer door panel 3 and the inner door panel 2. This completes the assembly of the door lock and fixes the relative positions of the inner door panel 2 and the outer door panel 3.

[0066] The connecting part 11 includes a first mounting surface 112 of the inner door panel along the second end face of the first orientation. The connecting part 11 is recessed with a receiving groove 111 along the first end face of the first orientation, and a door lock mounting position is provided on the groove wall of the receiving groove 111. After the door lock is installed at the door lock mounting position, the part of the door lock that locks with the vehicle body extends out of the first clearance hole 113 of the door lock, so that there is no need to punch the receiving groove 111 on the inner door panel 2, thereby effectively reducing the punching depth of the inner door panel 2 and effectively improving the flexibility of the door lock arrangement.

[0067] Secondly, the connecting part 11 includes the first mounting surface 112 of the inner door panel along the second end face of the first orientation, and the supporting part 12 of the outer door panel is far away from the second end face relative to the first end face, so that compared with the prior art, the connecting structure 1 can be used to assemble the door lock and to support the outer door panel 3. The connecting structure 1 has integrated functions, simple structure, few parts, and is convenient for production and disassembly.

[0068] Furthermore, the connecting portion 11 includes a first mounting surface 112 of the inner door panel along the second end face of the first orientation. It is understood that the first mounting surface 112 of the inner door panel is located between the inner door panel 2 and the outer door panel 3. Thus, when the door assembly is in the closed state, the connecting structure 1 can effectively reduce the occupancy rate of the vehicle interior space compared with the prior art.

[0069] Thus, by adopting this connecting structure 1, on the one hand, it can reduce the stamping depth of the inner door panel 2 and improve the flexibility of the door lock arrangement, and also support the outer door panel 3; on the other hand, the connecting structure 1 can effectively reduce the occupancy rate of the vehicle's interior space; furthermore, the connecting structure 1 has a simple structure, few parts, and is convenient for production and disassembly.

[0070] Specifically, the side of the inner door panel 2 closest to the outer side is the side of the inner door panel 2 closest to the outer door panel 3.

[0071] Specifically, such as Figure 5 As shown, after the outer door panel 3 is supported on the outer door panel support part 12, the outer door panel 3 covers the opening of the receiving groove 111 along the orthogonal projection of the first orientation.

[0072] Specifically, in this embodiment, as Figure 1-4 As shown, the connecting part 11 has a first connecting hole 114 at the door lock mounting position. The first connecting hole 114 is a threaded connection hole or a snap-fit ​​hole, etc. The door lock is detachably connected to the connecting part 11 through the first connecting hole 114 to facilitate maintenance and installation / removal of the door lock. In other embodiments, the door lock can also be welded and fixed to the door lock mounting position of the connecting part 11, etc. It is understood that the first connecting hole 114 and the door lock first clearance hole 113 are independent holes.

[0073] Optionally, such as Figure 1-3 As shown, the outer door panel support 12 is located on one side of the connecting portion 11 along the second orientation. The first orientation and the second orientation are set at an angle. Specifically, in this embodiment, taking the door assembly as a tailgate assembly as an example, when the door assembly is in the closed state, the outer door panel support 12 is located above the connecting portion 11 along the second orientation. This makes the outer door panel support 12 positioned close to the middle area of ​​the outer door panel 3, thereby further improving the effect and quality of the outer door panel support 12 in supporting the outer door panel 3. It can be understood that, for the door assembly as a tailgate assembly, when the door assembly is in the closed state, the door assembly is in the state of closing the trunk.

[0074] In other embodiments, the outer door panel support portion 12 may be positioned on one side of the connecting portion 11 along the third orientation. The plane containing the first and second orientations forms an angle with the third orientation.

[0075] In other embodiments, two door outer panel support portions 12 may be provided, with the two door outer panel support portions 12 corresponding to each other on both sides of the connecting portion 11 along the third orientation. This can further improve the effect and quality of supporting the door outer panel 3.

[0076] In other embodiments, the outer door panel support 12 may include a first sub-support and two second sub-supports. The first sub-support is located on one side of the connecting portion 11 along a second orientation, and the two second sub-supports are located on opposite sides of the connecting portion 11 along a third orientation. This can further improve the effect and quality of supporting the outer door panel 3.

[0077] In other embodiments, the outer panel support portion 12 may be arranged in a ring around the outer periphery of the connecting portion 11.

[0078] Specifically, in this embodiment, Figure 5 The direction ab in the diagram is the first orientation; Figure 1 The cd direction in the diagram is the second orientation; Figure 1 The ef direction in the diagram is the third orientation. The first orientation is perpendicular to the second orientation and also perpendicular to the third orientation.

[0079] Optionally, an elastic support member is fixedly provided on the outer door panel support portion 12. Along the first orientation, the elastic support member is located on the side of the outer door panel support portion 12 away from the receiving groove 111. Specifically, the outer door panel 3 is supported on the elastic support member along the first orientation. This not only supports the outer door panel 3, reducing the risk of denting or deformation of the outer door panel 3 under external forces, but also buffers and absorbs vibrations of the outer door panel 3.

[0080] Further optional, such as Figure 1 and Figure 3 As shown, the outer door panel support portion 12 is provided with a first groove 121, and the elastic support member is partially accommodated in the first groove 121. This defines the installation position of the elastic support member on the outer door panel support portion 12.

[0081] Alternatively, the groove wall of the first groove 121 is coated with an adhesive layer, and the elastic support is partially accommodated in the first groove 121. The adhesive layer bonds the portion of the elastic support accommodated in the first groove 121 to the groove wall of the first groove 121. This fixes the position of the elastic support on the door outer panel support 12, preventing the elastic support from failing due to displacement.

[0082] Alternatively, the elastic support is an expanding adhesive filled between the first groove 121 and the outer door panel 3. The expanding adhesive provides both support and cushioning / vibration absorption for the outer door panel 3.

[0083] In other embodiments, the elastic support member may also be made of an elastic material such as rubber. Furthermore, for the elastic support member made of an elastic material such as rubber, the elastic support member may also be fixed to the outer door panel support portion 12 by means of interference fit or other methods.

[0084] Optionally, a reinforcing rib is provided at the connection between the connecting part 11 and the outer door panel support part 12. Since the connecting part 11 and the outer door panel support part 12 are distributed along the first directional interval, the reinforcing rib at the connection between the connecting part 11 and the outer door panel support part 12 can effectively reduce the risk of deformation or even breakage at the connection between the connecting part 11 and the outer door panel support part 12 under external force, thereby effectively improving the reliability of the outer door panel 3 supported by the outer door panel support part 12.

[0085] Further, optionally, in this embodiment, such as Figure 1 and Figure 3As shown, the reinforcing rib is a second groove 13 formed at the connection between the connecting part 11 and the outer door panel support part 12. This effectively reduces the risk of deformation or even breakage at the connection between the connecting part 11 and the outer door panel support part 12 under external force, and also effectively improves the lightweight effect of the connection structure 1.

[0086] Alternatively, in this embodiment, the reinforcing rib is stamped at the connection between the connecting portion 11 and the outer door panel support portion 12. That is, a second groove 13 is formed at the connection between the connecting portion 11 and the outer door panel support portion 12 through stamping. The depth direction of the second groove 13 extends along a second orientation. This effectively improves the strength and rigidity of the formed reinforcing rib while enhancing weight reduction.

[0087] Stamping refers to the process of applying external force to metal sheets (such as steel plates and strips) using a press and molds, and obtaining metal parts with the required shape, size and performance through plastic deformation or separation processes.

[0088] Optionally, there are multiple second grooves 13, which are spaced apart at the connection between the connecting portion 11 and the outer door panel support portion 12. This further reduces the risk of deformation or even breakage at the connection between the connecting portion 11 and the outer door panel support portion 12 under external force. In this embodiment, as... Figure 1 As shown, an exemplary configuration is provided with three second grooves 13, which are distributed along a third directional interval.

[0089] In other embodiments, the reinforcing rib may be provided as an independent part, and the reinforcing rib may be connected to the connecting part 11 and the door outer panel support part 12 by means of welding, bolts and nuts, or screws.

[0090] The groove wall of the receiving groove 111 is also provided with a vibration absorber mounting position. Specifically, the vibration absorber 4 is installed at the vibration absorber mounting position of the connecting part 11 and is housed in the receiving groove 111. With this arrangement, compared with the prior art, it is not necessary to separately form a cavity for housing the vibration absorber 4 on the inner door panel 2, and compared with the prior art, it is not necessary to set an additional reinforcing plate to enhance the connection reliability of the vibration absorber 4 to the inner door panel 2, which further simplifies the structure of the door assembly and further improves the lightweight effect; secondly, the vibration absorber 4 is housed in the receiving groove 111, which can effectively reduce the vehicle interior space occupied by the vibration absorber 4 compared with the prior art.

[0091] Specifically, in this embodiment, as Figure 1-4As shown, the connecting part 11 has a second connecting hole 115 at the vibration absorber mounting position. The second connecting hole 115 is a threaded connection hole or a snap-fit ​​hole, etc. The vibration absorber 4 is detachably connected to the connecting part 11 through the second connecting hole 115 to facilitate maintenance and disassembly of the vibration absorber 4. In other embodiments, the vibration absorber 4 can also be welded and fixed to the vibration absorber mounting position of the connecting part 11, etc.

[0092] Optionally, the door lock mounting positions and the vibration absorber mounting positions are distributed along a second directional interval. For example... Figure 1-4 As shown, the first connecting hole 114 and the second connecting hole 115 are distributed along the second directional interval.

[0093] When the connection structure 1 is applied to the tailgate assembly, since the structure that locks the door lock on the vehicle body is usually located at the bottom of the trunk along the height direction, the door lock mounting position and the vibration absorber mounting position are arranged at intervals along the second orientation. When the door assembly is closed, the door lock mounting position is located below the vibration absorber mounting position along the second orientation.

[0094] This configuration allows the door lock to be effectively locked to the vehicle body. Secondly, it allows the receiving groove 111 to accommodate the vibration absorber 4 and the door lock. The vibration absorber 4 is positioned close to the middle area of ​​the door assembly, which can further improve the vibration absorption effect of the vibration absorber 4 on the door assembly and effectively reduce the size of the receiving groove 111 along the third direction.

[0095] As an alternative, the door lock mounting positions and vibration absorber mounting positions can also be arranged along the third directional interval.

[0096] Optionally, the groove wall of the receiving groove 111 is further provided with an integrated mounting position, which includes a trim panel fixing position and / or a wiring harness fixing position. In this embodiment, the integrated mounting position includes a trim panel fixing position and a wiring harness fixing position. In other embodiments, only the trim panel fixing position or the wiring harness fixing position may be provided on the groove wall of the receiving groove 111.

[0097] For the integrated mounting position including the interior panel fixing position, it can fix the relative position of the interior panel and the connecting structure 1, and facilitate the fixing of the relative position of the interior panel and the door inner panel 2, thereby effectively improving the connection reliability of the interior panel and further improving the space utilization of the receiving slot 111.

[0098] Furthermore, such as Figure 1-4 As shown, for the integrated mounting position including the interior panel fixing position, the connecting part 11 is provided with a third connecting hole 116 at the interior panel fixing position. The third connecting hole 116 is a threaded connection hole or a snap-fit ​​hole, etc. The interior panel is detachably connected to the connecting part 11 through the third connecting hole 116 to facilitate maintenance and installation / removal of the interior panel.

[0099] For integrated mounting positions, including wiring harness fixing positions, it is convenient to organize the wiring harness of the door lock and other electrical components such as the door assembly lights, and can further improve the space utilization of the receiving slot 111.

[0100] Furthermore, for the integrated mounting position including the wiring harness fixing position, the connecting part 11 is provided with a fourth connecting hole 117 at the wiring harness fixing position. The fourth connecting hole 117 is a threaded connection hole or a snap-fit ​​hole, etc. Taking the fourth connecting hole 117 as a snap-fit ​​hole as an example, a wiring harness clip is held in the fourth connecting hole 117, and the wiring harness of the door lock, the lighting lamp, etc. are organized by the wiring harness clip.

[0101] Optionally, such as Figure 1-4 As shown, along the third orientation, a portion of the integrated mounting position is located on one side of the door lock mounting position and the vibration absorber mounting position, while the remaining portion is located on the other side. This arrangement allows for a larger coverage area of ​​the integrated mounting position while maintaining the same volume of the receiving groove 111, thus making efficient use of the internal space of the receiving groove 111 and further improving its space utilization rate. Secondly, it ensures that the connecting portion 11 experiences approximately uniform stress, thereby extending the service life of the connecting structure 1.

[0102] As an alternative, the integrated mounting position is located on one side of the door lock mounting position and the vibration absorber mounting position along the third orientation.

[0103] Optionally, such as Figure 1-5 As shown, the groove wall of the receiving groove 111 is provided with a process through hole 118. The door lock mounting position, the vibration absorber mounting position, and the integrated mounting position are all located on the outer periphery of the process through hole 118. This arrangement allows for the inspection and maintenance of the door lock, vibration absorber 4, etc., through the process through hole 118, thereby improving inspection and maintenance efficiency.

[0104] In this embodiment, as Figure 1-5As shown, the receiving groove 111 has a rectangular cross-section along the first orientation; along the first orientation, from the opening of the receiving groove 111 to the inner bottom wall 1113 of the receiving groove 111, the cross-sectional area of ​​the receiving groove 111 gradually decreases. That is, the receiving groove 111 is a basin-shaped structure with a rectangular cross-section along the first orientation. Further, the receiving groove 111 includes a first inner sidewall 1111 and a second inner sidewall 1112 that are opposite to each other and spaced apart along a second orientation, a third inner sidewall and a fourth inner sidewall that are opposite to each other and spaced apart along a third orientation, and an inner bottom wall 1113; the third inner sidewall is connected between the first inner sidewall 1111 and the second inner sidewall 1112 on one side along the third orientation, and the fourth inner sidewall connecting portion 11 is between the first inner sidewall 1111 and the second inner sidewall 1112 on the other side along the third orientation; the first inner sidewall 1111, the second inner sidewall 1112, the third inner sidewall and the fourth inner sidewall are all connected to the inner bottom wall 1113 and are arranged with the inner bottom wall 1113 to form the receiving groove 111.

[0105] It is understood that the door lock mounting position is located on the first inner sidewall 1111 and / or the inner bottom wall 1113, and the vibration absorber mounting position is located on the first inner sidewall 1111 and / or the inner bottom wall 1113, and the door lock mounting position and the vibration absorber mounting position are distributed on both sides of the process through hole 118 along the second directional interval.

[0106] It is understood that a portion of the integrated mounting position is located on the third inner sidewall and / or inner bottom wall 1113, and is situated on one side of the door lock mounting position and the vibration absorber mounting position; the remaining portion of the integrated mounting position is located on the fourth inner sidewall and / or inner bottom wall 1113, and is situated on the other side of the door lock mounting position and the vibration absorber mounting position. Alternatively, all integrated mounting positions are located on the third inner sidewall and / or inner bottom wall 1113, and are situated on one side of the door lock mounting position and the vibration absorber mounting position. Alternatively, all integrated mounting positions are located on the fourth inner sidewall and / or inner bottom wall 1113, and are situated on one side of the door lock mounting position and the vibration absorber mounting position. Alternatively, the integrated mounting position is located on the inner bottom wall 1113 and / or the first inner sidewall 1111 and / or the second inner sidewall 1112.

[0107] In this embodiment, as Figure 1-5 As shown, the process through hole 118 is provided in the inner bottom wall 1113. There are two first connecting holes 114 and two second connecting holes 115. The first door lock clearance hole 113 and the two first connecting holes 114 are all provided in the first inner side wall 1111, and the two second connecting holes 115 are provided in the second inner side wall 1112. When the door assembly is in the closed state, the first inner side wall 1111 is located below the second inner side wall 1112 along the second orientation.

[0108] Furthermore, in this embodiment, as Figure 1-4As shown, there are two third connecting holes 116 and two fourth connecting holes 117. Along the third orientation, one of the third connecting holes 116 and one of the fourth connecting holes 117 are located on one side of the process through hole 118, and the other third connecting hole 116 and the other fourth connecting hole 117 are located on the other side of the process through hole 118.

[0109] In other embodiments, the receiving groove 111 may also be provided with a circular cross-section along the first orientation. Along the first orientation, from the opening of the receiving groove 111 to the inner bottom wall 1113 of the receiving groove 111, the cross-sectional area of ​​the receiving groove 111 gradually decreases or remains constant. Further, for the receiving groove 111 having a circular cross-section along the first orientation, and the cross-sectional area of ​​the receiving groove 111 remaining constant along the first orientation from the opening of the receiving groove 111 to the inner bottom wall 1113 of the receiving groove 111, the receiving groove 111 is a cylindrical structure with a circular cross-section along the first orientation. For the receiving groove 111 having a circular cross-section along the first orientation, and the cross-sectional area of ​​the receiving groove 111 gradually decreasing along the first orientation from the opening of the receiving groove 111 to the inner bottom wall 1113 of the receiving groove 111, the receiving groove 111 is a basin-shaped structure with a circular cross-section along the first orientation.

[0110] It is understandable that the number of the first connecting hole 114, the second connecting hole 115, the third connecting hole 116 and the fourth connecting hole 117 can be adjusted adaptively according to the actual working conditions.

[0111] In this embodiment, the first mounting surface 112 of the inner door panel is welded and fixed to the inner door panel 2. In other embodiments, the connecting part 11 can also be connected to the inner door panel 2 by riveting, bolt and nut connection, or screw connection, etc.

[0112] Among them, such as Figure 2 As shown, the first mounting surface 112 of the inner door panel includes a first sub-mounting surface 1121, the first sub-mounting surface 1121 being located on the outer periphery of the opening of the receiving groove 111 along a first orientation. Specifically, as... Figure 6 As shown, the inner panel 2 of the door has a socket 21. Figure 3-6 As shown, after the portion of the connecting structure 1 containing the groove 111 is inserted into the insertion hole 21 of the inner door panel 2 along the first orientation, the first sub-mounting surface 1121 is connected to the inner door panel 2.

[0113] Optionally, such as Figure 2 and Figure 5As shown, the first mounting surface 112 of the door inner panel also includes a second sub-mounting surface 1122 connected to the first sub-mounting surface 1121. After the portion of the receiving groove 111 on the connecting structure 1 is inserted into the insertion hole 21 of the door inner panel 2, both the first sub-mounting surface 1121 and the second sub-mounting surface 1122 are connected to the door inner panel 2. This can further increase the connection area between the connecting structure 1 and the door inner panel 2, thereby further improving the reliability of the connecting part 11 fixed to the door inner panel 2.

[0114] Optionally, such as Figure 2 and Figure 5 As shown, the second sub-mounting surface 1122 is located within the opening along the orthographic projection of the first orientation. This allows for a further increase in the connection area between the connection structure 1 and the inner door panel 2, while avoiding an increase in the volume and space occupancy of the connection portion 11.

[0115] Optionally, such as Figure 2 and Figure 5 As shown, the second sub-mounting surface 1122 is located on one side of the receiving groove 111 along the second orientation. In this embodiment, when the door assembly is in the closed state, the second sub-mounting surface 1122 is preferably located below the receiving groove 111 along the second orientation. With this configuration, when the door assembly is in the closed state, the inner door panel 2 can support the connecting structure 1 through the second sub-mounting surface 1122, thereby further improving the reliability of the connecting structure 1 fixed to the inner door panel 2, and effectively improving the structural strength and rigidity of the overall structure formed by the connecting structure 1 and the inner door panel 2.

[0116] As an alternative, the second sub-mounting surface 1122 is located on one side of the receiving groove 111 along the third orientation. This can further increase the connection area between the connecting structure 1 and the inner door panel 2 without increasing the processing difficulty of the inner door panel 2, thereby further improving the reliability of the connecting structure 1 fixed to the inner door panel 2.

[0117] In this embodiment, as Figure 2 and Figure 5 As shown, the first mounting surface 112 of the inner door panel includes a first sub-mounting surface 1121 and a second sub-mounting surface 1122 connected to each other. The first sub-mounting surface 1121 is located on the outer periphery of the opening of the receiving groove 111 along the first orientation. The second sub-mounting surface 1122 is located inside the opening along the first orientation, and when the door assembly is in the closed state, the second sub-mounting surface 1122 is located below the receiving groove 111 along the second orientation.

[0118] Furthermore, in this embodiment, as Figure 2 and Figure 4-6As shown, the inner door panel 2 is provided with a connecting ear 22, and the connecting ear 22 is provided with a fifth connecting hole 221; the second sub-mounting surface 1122 is connected to the connecting ear 22, and the first connecting hole 114 communicates with the fifth connecting hole 221. Specifically, after the portion of the receiving groove 111 on the connecting structure 1 is inserted into the insertion hole 21 of the inner door panel 2 along the first orientation, the first connecting hole 114 communicates with the fifth connecting hole 221, and then the second sub-mounting surface 1122 is connected to the connecting ear 22. The door lock is detachably connected to the connecting part 11 and the inner door panel 2 through the first connecting hole 114 and the fifth connecting hole 221. This arrangement can further improve the installation reliability and stability of the door lock.

[0119] Furthermore, in this embodiment, as Figure 2 and Figure 4-6 As shown, there are two connecting ears 22, which are distributed along a third directional interval and form a second door lock clearance hole 23 between them. The second door lock clearance hole 23 is connected to the insertion hole 21. After the portion of the receiving groove 111 on the connecting structure 1 is inserted into the insertion hole 21 of the inner panel 2 of the door, the second door lock clearance hole 23 is connected to the first door lock clearance hole 113. Furthermore, there are two sets of first connecting holes 114; each connecting ear 22 is provided with a set of fifth connecting holes 221, and the two sets of first connecting holes 114 and the two sets of fifth connecting holes 221 are arranged one-to-one. While ensuring that the door lock can partially extend out of the first door lock clearance hole 113 and the second door lock clearance hole 23, the installation reliability and stability of the door lock are further improved.

[0120] Optionally, such as Figure 1-3 As shown, the connecting structure 1 also includes a reinforcing portion 14 connected to the connecting portion 11, and the reinforcing portion 14 forms a second mounting surface 141 for the inner door panel. After the portion of the connecting structure 1 containing the receiving groove 111 is inserted into the insertion hole 21 of the inner door panel 2 along the first orientation, the second mounting surface 141 of the inner door panel is connected to the inner door panel 2. This can further increase the connection area between the connecting structure 1 and the inner door panel 2, thereby further improving the reliability of the connecting structure 1 being fixed to the inner door panel 2.

[0121] In this embodiment, the second mounting surface 141 of the inner door panel is riveted to the inner door panel 2. In other embodiments, the reinforcing part 14 may also be connected to the inner door panel 2 by welding, bolt and nut connection, or screw connection, etc.

[0122] Optionally, the dimension of the reinforcing part 14 along the third orientation is smaller than the dimension of the connecting part 11 along the third orientation. That is, the dimension of the second mounting surface 141 of the inner door panel along the third orientation is smaller than the dimension of the connecting part 11 along the third orientation. This achieves both increasing the connection area between the connecting structure 1 and the inner door panel 2 and reducing the weight of the connecting structure.

[0123] As an alternative, the dimension of the reinforcing part 14 along the third orientation is equal to the dimension of the connecting part 11 along the third orientation. As another alternative, the dimension of the reinforcing part 14 along the third orientation is greater than the dimension of the connecting part 11 along the third orientation.

[0124] Optionally, there may be multiple reinforcing parts 14, which are distributed at intervals along a third orientation. This can further increase the connection area between the connecting structure 1 and the inner door panel 2, thereby further improving the reliability of the connecting structure 1 being fixed to the inner door panel 2.

[0125] In this embodiment, the reinforcement 14 is configured such that its dimension along the third orientation is smaller than that of the connecting portion 11 along the third orientation, and the number of reinforcements 14 is two.

[0126] Among them, such as Figure 2 and Figure 3 As shown, the second mounting surface 141 of the inner door panel includes a third sub-mounting surface 1411. After the portion of the receiving groove 111 on the connecting structure 1 is inserted into the insertion hole 21 of the inner door panel 2 along the first orientation, the third sub-mounting surface 1411 is connected to the inner door panel 2.

[0127] Optionally, such as Figure 2 and Figure 3 As shown, the second mounting surface 141 of the inner door panel also includes a fourth sub-mounting surface 1412 connected to the third sub-mounting surface 1411 and arranged at an angle. After the portion of the receiving groove 111 on the connecting structure 1 is inserted into the insertion hole 21 of the inner door panel 2 along the first orientation, both the third sub-mounting surface 1411 and the fourth sub-mounting surface 1412 are connected to the inner door panel 2. This can further increase the connection area between the connecting structure 1 and the inner door panel 2, thereby further improving the reliability of the connecting part 11 being fixed to the inner door panel 2; secondly, the angle arrangement of the third sub-mounting surface 1411 and the fourth sub-mounting surface 1412 can further improve the structural strength and rigidity of the overall structure formed by the connecting structure 1 and the inner door panel 2.

[0128] In this embodiment, as Figure 1-3 As shown, the third sub-mounting surface 1411 and the fourth sub-mounting surface 1412 are set at an obtuse angle. The third sub-mounting surface 1411 and the fourth sub-mounting surface 1412 are distributed sequentially along the first orientation. The third sub-mounting surface 1411 is located between the connecting portion 11 and the fourth sub-mounting surface 1412 along the second orientation.

[0129] Understandably, depending on the structural form of the inner bottom plate, the second mounting surface 141 of the inner door panel can be adapted to include a fifth sub-mounting surface connected to the fourth sub-mounting surface 1412, etc.

[0130] Optionally, the reinforcing part 14 is located on one side of the connecting part 11 along the second orientation. Specifically, in this embodiment, when the door assembly is in the closed state, the reinforcing part 14 is preferably located below the connecting part 11 along the second orientation. With this configuration, when the door assembly is in the closed state, the inner door panel 2 can support the connecting structure 1 through the second mounting surface 141 of the inner door panel, thereby further improving the reliability of the connecting structure 1 fixed to the inner door panel 2, and further improving the structural strength and rigidity of the overall structure formed by the connecting structure 1 and the inner door panel 2.

[0131] Preferably, such as Figure 1-3 As shown, the outer door panel support 12 is located on one side of the connecting portion 11 along the second orientation, and the reinforcing portion 14 is located on the other side of the connecting portion 11 along the second orientation. In this embodiment, when the door assembly is in the closed state, the outer door panel support 12 is located above the connecting portion 11 along the second orientation, and the reinforcing portion 14 is located below the connecting portion 11 along the second orientation. This improves the effectiveness and quality of the outer door panel support 12 in supporting the outer door panel 3 while simplifying the structure, and also enhances the structural strength and rigidity of the overall structure formed by the connecting structure 1 and the inner door panel 2.

[0132] As an alternative, the reinforcing part 14 can be located on one side of the connecting part 11 along the third orientation; or, the connecting part 11 can be provided with reinforcing parts 14 on both sides along the third orientation. Both can further increase the connection area between the connecting structure 1 and the inner door panel 2.

[0133] In this embodiment, the connecting part 11, the outer panel support part 12, and the reinforcing part 14 of the connecting structure 1 are integrally stamped from sheet metal. Using sheet metal stamping to form the connecting structure 1 results in high production efficiency, low production cost, and stable quality of the produced connecting structure 1.

[0134] Specifically, in this embodiment, the connecting structure 1 is integrally stamped from an aluminum plate. Aluminum plates have advantages such as being lightweight, having high tensile strength, good plasticity, and being corrosion resistant.

[0135] As an alternative, the connecting part 11, the outer door panel support part 12, and the reinforcing part 14 can be formed separately from sheet metal, and then the connecting part 11, the outer door panel support part 12, and the reinforcing part 14 can be spliced ​​together to form the connecting structure 1.

[0136] Optionally, such as Figure 1-4 As shown, the inner bottom wall 1113 of the receiving groove 111 is provided with positioning holes 119. Specifically, when the positioning holes 119 are circular, the number of positioning holes 119 is at least two. When the positioning holes 119 are non-circular, the number of positioning holes 119 is at least one.

[0137] When the connecting part 11, the outer panel support part 12, and the reinforcing part 14 of the connecting structure 1 are integrally stamped from sheet metal, it is convenient to position the relative positions of the sheet metal and the stamping die, thereby improving the quality of the stamped structure. Specifically, the stamping die is provided with a first positioning post that inserts into the positioning hole 119.

[0138] When the connecting structure 1 is installed on the inner door panel 2, the relative position of the connecting structure 1 and the inner door panel 2 can be positioned to prevent the connecting structure 1 from shifting, thereby effectively ensuring the welding accuracy of welding the first mounting surface 112 of the inner door panel to the inner door panel 2. Specifically, the inner door panel 2 is provided with a second positioning post that is inserted into the positioning hole 119.

[0139] In this embodiment, as Figure 1-4 As shown, there are two positioning holes 119, both of which are round holes; along the third orientation, one positioning hole 119 is located on one side of the process through hole 118, and the other positioning hole 119 is located on the other side of the process through hole 118.

[0140] This utility model also provides a door assembly, such as Figure 1-6 As shown, the door includes an inner panel 2 and an outer panel 3, and also includes the aforementioned connecting structure 1. The first mounting surface 112 of the inner panel is connected to the inner panel 2, and the first mounting surface 112 of the inner panel is located between the inner panel 2 and the outer panel 3. The outer panel 3 is supported by the outer panel support portion 12.

[0141] By adopting the above-mentioned connection structure 1, the stamping depth of the inner door panel 2 can be effectively reduced, the flexibility of the door lock arrangement can be improved, the occupancy rate of the door assembly in the vehicle interior space can be effectively reduced, and the structure of the door assembly can be effectively simplified, making production and disassembly convenient.

[0142] Specifically, such as Figure 1-6 As shown, the inner door panel 2 is provided with an insertion hole 21. The portion of the connecting part 11 containing the receiving groove 111 is inserted into the insertion hole 21 along the first orientation, thereby connecting the first clearance hole 113 and the second clearance hole 23 of the door lock. The first mounting surface 112 of the inner door panel is located between the inner door panel 2 and the outer door panel 3. Specifically, after the portion of the connecting part 11 containing the receiving groove 111 is inserted into the insertion hole 21 along the first orientation, the first mounting surface 112 of the inner door panel is connected to the inner door panel 2.

[0143] Specifically, such as Figure 1-4 As shown, the door assembly also includes a door lock, which is fixed to the door lock mounting position of the connecting structure 1 via the first connecting hole 114.

[0144] Specifically, such as Figure 1-5 As shown, the door assembly also includes a vibration absorber 4, which is fixed to the vibration absorber mounting position of the connecting structure 1 through the second connecting hole 115.

[0145] Specifically, such as Figure 1-4 As shown, the door assembly also includes an interior panel, which is fixed to the interior panel fixing position of the connecting structure 1 via a third connecting hole 116.

[0146] Specifically, the door assembly also includes wiring harness clips, which are used to organize the wiring harnesses for the door locks, lights, etc. For example... Figure 1-4 As shown, the wire harness clip is fixed to the wire harness fixing position of the connection structure 1 through the fourth connecting hole 117.

[0147] Specifically, the specific structures of the door lock, vibration absorber 4, wiring harness clip, door outer panel 3, and interior panel are all existing technologies, so they will not be described in detail here.

[0148] Specifically, in this embodiment, the door assembly is taken as the tailgate assembly, that is, the inner door panel 2 is the tailgate inner panel, the outer door panel 3 is the tailgate outer panel, and the door lock is the tailgate lock.

[0149] Preferably, such as Figure 5 As shown, the thickness of the connecting structure 1 is greater than that of the inner door panel 2. This effectively improves the reliability of fixing the door lock, vibration absorber 4, interior panel, and wiring harness clips to the connecting structure 1, and eliminates the need for additional reinforcing plates to improve connection reliability.

[0150] In other embodiments, the thickness of the connecting structure 1 may be equal to the thickness of the inner door panel 2. Reinforcing plates may also be provided at least at the door lock mounting position, the vibration absorber mounting position, and the interior panel fixing position.

[0151] This utility model also provides a vehicle, including the aforementioned connecting structure 1 or the aforementioned door assembly. It can effectively improve the vehicle's working performance and weight reduction, and is convenient for production and assembly / disassembly.

[0152] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
