It should also be noted that the aforementioned Z axis, Y axis, and X axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0027] Combination Figure 1 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a hidden door handle mounting structure, including a waistline reinforcement plate 1 and a handle mounting plate 2, the waistline reinforcement plate 1 and the handle mounting plate 2 are respectively integrally formed, and the handle mounting plate 2 includes a mounting plate body 21 and a supporting leg 22, the two ends of the mounting plate body 21 are respectively connected to the waistline reinforcement plate 1 and the supporting leg 22, and the supporting leg 22 is used to be connected to the door inner panel 100.

[0028] It should be noted that the left and right doors of a vehicle are usually provided with hidden door handle installation structures, and are usually arranged symmetrically on the left and right. Figure 3 and Figure 4 The example given in the figure is that the hidden door handle mounting structure is installed on the left door.

[0029] Specifically, the waistline reinforcement plate 1 and the handle mounting plate 2 are independent components that are integrally formed, and the two can be assembled by, for example, welding, clamping, bolting, etc. That is to say, the hidden door handle mounting structure in this embodiment is a split mounting structure, rather than a traditional one-piece stamping structure. The waistline reinforcement plate 1 and the handle mounting plate 2 are usually arranged between the door inner panel 300 and the door outer panel, and are connected to both the door inner panel 300 and the door outer panel. During assembly, the waistline reinforcement plate 1 and the handle mounting plate 2 are usually connected to the door inner panel 300 by welding, so as to achieve the installation and fixation of the waistline reinforcement plate 1 and the handle mounting plate 2 on the door inner panel 300. At the same time, the waistline reinforcement plate 1 and the handle mounting plate 2 are also connected to the door outer panel to support the door outer panel. The waistline reinforcement plate 1 is usually located below the vehicle window, and along the front and rear direction of the vehicle (i.e. Figure 1 The handle mounting plate 2 is generally located at the rear half of the waistline reinforcement plate 1. The handle mounting plate 2 may be located above the waistline reinforcement plate 1 (i.e. Figure 1 The positive direction of the Z axis in the figure) can also be set below the waistline reinforcement plate 1 (i.e. Figure 1 In other words, the handle mounting plate 2 can be connected to the waistline reinforcement plate 1 at Figure 1 The positive or negative end of the middle Z axis, that is, the lower end or upper end of the waistline reinforcement plate 1, for example, Figure 1An example is given in which the handle mounting plate 2 is connected to the lower end of the waistline reinforcement plate 1. In actual application, the design can be selected according to the arrangement position of the hidden handle on the door, and no specific limitation is made here.

[0030] More specifically, the integrated handle mounting plate 2 is usually composed of two parts, namely, a mounting plate body 21 and a support leg 22, wherein the mounting plate body 21 and the support leg 22 are usually processed into the handle mounting plate 2 by an integrated stamping method, and one end of the support leg 22 is connected to the mounting plate body 21, and the other end is used to connect to the door inner panel 300 by, for example, welding, etc. At the same time, the opposite ends of the mounting plate body 21 are respectively connected to the support leg 22 and the waistline reinforcement plate 1, for example Figure 1 As shown, the upper end of the mounting plate body 21 is connected to the lower end of the waistline reinforcement plate 1 , and the lower end of the mounting plate body 21 is connected to one end of the support leg 22 .

[0031] The hidden door handle mounting structure in this embodiment can be manufactured by processing the waistline reinforcement plate 1 and the handle mounting plate 2 in an integrated manner, and assembled by welding, so as to use a split mounting structure to replace the traditional integrated mounting structure. This can not only reduce the processing difficulty and weight of the waistline reinforcement plate 1, but also simplify the structure and production process of the stamping die, so that the waistline reinforcement plate 1 and the handle mounting plate 2 are easier and more efficient to manufacture by stamping. At the same time, by arranging a support leg 22 on the mounting plate body 21 of the handle mounting plate 2, the support leg 22 can be used to improve the rigidity of the handle mounting plate 2 and even the hidden door handle mounting structure. In this way, during assembly, the waistline reinforcement plate 1, the mounting plate body 21 and the support leg 22 can be connected to the door inner panel 300 respectively, and the waistline reinforcement plate 1 and the mounting plate body 21 can be connected to the door outer panel respectively, so as to improve the supporting capacity of the hidden door handle mounting structure to the door outer panel, thereby improving the anti-dent performance of the door outer panel.

[0032] Optionally, the mounting plate body 21 is welded to the waistline reinforcement plate 1 .

[0033] In the present embodiment, the waistline reinforcement plate 1 and the handle mounting plate 2 are preferably connected by welding, which not only ensures a firm connection with high reliability, but also eliminates the need for additional connection structures such as connection holes and snap-on structures on the waistline reinforcement plate 1 and the handle mounting plate 2 to achieve the connection. This makes the structures of the waistline reinforcement plate 1 and the handle mounting plate 2 simpler, thereby simplifying the structure of the stamping die and further reducing the production cost.

[0034] Optionally, combined Figure 1 and Figure 5As shown, the mounting plate body 21 includes a first recessed portion 211 and a boss portion 212 arranged around the recessed portion 211, the boss portion 212 is used to be convexly arranged toward the outside of the vehicle, the first recessed portion 211 is used to be recessed toward the inside of the vehicle, and the first recessed portion 211 is provided with a handle through hole 214 for avoiding a hidden handle and a mounting portion 215 for installing a hidden handle, the waistline reinforcement plate 1 and the support leg 22 are respectively connected to the boss portion 212.

[0035] Among them, it should be noted that, for the hidden door handle installation structure set on the left door, the direction inside the vehicle is the direction pointing to the right side of the left door, and accordingly, the direction outside the vehicle is the direction pointing to the left side of the left door, and for the hidden door handle installation structure set on the right door, the direction inside the vehicle is the direction pointing to the left side of the right door, and accordingly, the direction outside the vehicle is the direction pointing to the right side of the right door.

[0036] Specifically, the handle through hole 214 is usually a rectangular hole with a large opening area, which can allow part of the structure of the hidden handle to pass through the mounting plate body 21 through the handle through hole 214, and the handle through hole 214 is usually set in the middle of the recessed portion 211, which makes the first recessed portion 211 roughly annular in structure, and the boss portion 212 is usually also annular in structure, and is set around the first recessed portion 211 in a full circle. The mounting portion 215 can be a mounting hole, in which case the hidden handle is installed on the mounting plate body 21 by bolt connection, or the mounting portion 215 can be a snap-fit ​​structure, in which case the hidden handle is installed on the mounting plate body 21 by snap-fitting and fixing, which is not specifically limited here. Moreover, there are usually multiple mounting portions 215, and the multiple mounting portions 215 are spaced around the handle through hole 214 and distributed on the first recessed portion 211. Taking the hidden door handle installation structure on the left door as an example, the first recessed portion 211 is usually formed by the middle part of the mounting plate body 21 being recessed toward the inside of the vehicle along the Y-axis direction, that is, the first recessed portion 211 is formed by the middle part of the mounting plate body 21 being recessed toward the right side, and the boss portion 212 is usually formed by the part of the mounting plate body 21 located on the outer circle of the first recessed portion 211 protruding toward the outside of the vehicle along the Y-axis direction, that is, the boss portion 212 is formed by the part of the mounting plate body 21 located on the outer circle of the first recessed portion 211 protruding toward the left side. In addition, the waistline reinforcement plate 1 and the support leg 22 are usually connected to the two ends of the boss portion 212 in the up and down direction respectively.

[0037] In this embodiment, a first recessed portion 211 recessed toward the inside of the vehicle is provided on the mounting plate body 21, and a handle through hole 214 is provided in, for example, the middle portion of the first recessed portion 211, so as to avoid the hidden handle during installation, thereby providing more installation space and movement space for the hidden handle, ensuring that the hidden handle has sufficient space both during installation and when flipped open for activation. At the same time, a mounting portion 215 for mounting the hidden handle is provided on the first recessed portion 211, and a boss portion 212 protruding toward the outside of the vehicle is provided on the outer ring of the first recessed portion 211, so that the structure around the mounting portion 215 is roughly in the form of a concave-convex structure with a height difference, thereby greatly improving the rigidity of the structure around the handle installation point.

[0038] Optionally, combined Figure 5 As shown, a plurality of mounting portions 215 are provided, and center lines of the plurality of mounting portions 215 are arranged in parallel and are not coplanar.

[0039] In this embodiment, since the hidden handle is usually installed by three-point fixing in actual applications, three mounting portions 215 are usually used as a group of mounting portions 215. Specifically, there are usually at least three mounting portions 215 on the mounting plate body 21. Since the center lines of the at least three mounting portions 215 are arranged in parallel and not coplanar, there is at least one group of mounting portions 215 distributed in a triangle, such as Figure 5 Thus, when installing the hidden handle, three mounting portions 215 distributed in a triangle among the multiple mounting portions 215 can be selected as mounting points for the hidden handle for installation and fixing, thereby ensuring that the force at the mounting point of the handle is uniform and the stability is high.

[0040] Optionally, combined Figure 5 As shown, a reinforcing rib 216 is further provided on the first recessed portion 211 , and the reinforcing rib 216 is located between two adjacent mounting portions 215 .

[0041] In this embodiment, the reinforcing rib 216 is usually formed by a local portion of the first recessed portion 211 protruding toward the vehicle interior or vehicle exterior, and the number of reinforcing ribs 216 between two adjacent mounting portions 215 can be selected and set according to the spacing between the two adjacent mounting portions 215. For example, when the spacing between the two adjacent mounting portions 215 is large, two or three reinforcing ribs 216 can be selected to be set between the two mounting portions 215, and when the spacing between the two adjacent mounting portions 215 is small, one reinforcing rib 216 can be selected to be set between the two mounting portions 215. In this way, by setting the reinforcing rib 216 between the two adjacent mounting portions 215, the rigidity of the structure around the mounting portion 215 is improved, thereby further improving the rigidity at the handle mounting point.

[0042] Furthermore, combined with Figure 5 As shown, the boss portion 212 is provided with a first glue groove 217, and the mounting plate body 21 is used to bond with the door outer panel at the first glue groove 217. There are usually multiple first glue grooves 217, and these multiple first glue grooves 217 are arranged at intervals around the first recessed portion 211 on the boss portion 212. In this way, the connection between the handle mounting plate 2 and the door outer panel is achieved, ensuring that the handle mounting plate 2 can effectively support the door outer panel.

[0043] Optionally, combined Figure 5 As shown, a first flange structure 218 is provided on one side of the boss portion 212 along the left-right direction of the vehicle, and the first flange structure 218 is used to be connected to the door inner panel 300 .

[0044] In this embodiment, the first flange structure 218 is usually arranged at one end of the boss portion 212 facing the rear direction of the vehicle, and is used for welding with the window frame 310 of the door inner panel 300. In this way, the flange structure is utilized to realize the welding between the mounting plate body 21 and the door inner panel 300, and form a side force transmission structure, which is convenient for transferring the load borne by the handle mounting plate 2 to the door inner panel 300 to share the load, thereby improving the carrying capacity of the handle mounting plate 2.

[0045] Furthermore, combined with Figure 5 and Figure 6 As shown, the first recessed portion 211 is provided with a second flange structure 219, which is arranged along the edge of the handle through hole 216 and is located on the side of the first recessed portion 211 facing the door outer panel. In this embodiment, by arranging the second flange structure 219 on the edge of the handle through hole 216, the rigidity of the structure around the handle through hole 216 is improved. At the same time, the second flange structure 219 is arranged on the handle through hole 216, which can not only prevent the second flange structure 219 from occupying the space on the side of the mounting plate body 21 facing the vehicle interior, thereby reducing the occupied space of the mounting plate body 21, but also prevent the second flange structure 219 from interfering with the door inner panel 300.

[0046] Optionally, combined Figure 5 As shown, the support leg 22 includes a second recessed portion 221 and a third recessed portion 222 which are recessed toward the interior of the vehicle. The second recessed portion 221 is extended along the edge of the boss portion 212 away from the waistline reinforcement plate 1. One end of the third recessed portion 222 is cross-connected to the second recessed portion 221 and the boss portion 212, and the other end of the third recessed portion 222 is used to be connected to the door inner panel 300.

[0047] In this embodiment, based on the arrangement of the first recessed portion 211 along the edge of the inner periphery of the boss portion 212, a second recessed portion 221 is further arranged, and the second recessed portion 221 is arranged along the lower end edge of the outer periphery of the boss portion 212, so that both the inner and outer sides of the boss portion 212 form a concave surface, that is, the structure around the mounting portion 215 forms a concave-convex structure, so that the rigidity of the structure around the handle mounting point can be further improved. In addition, on the basis that the boss portion 212 is connected to the door inner panel 300 through the first flange structure 218, one end of the boss portion 212 away from the waistline reinforcement plate 1 and one end of the second recessed portion 221 are cross-connected with one end of the third recessed portion 222 respectively, and the other end of the third recessed portion 222 is connected to the door inner panel 300, so that the boss portion 212 and the supporting leg 22 together form a double-channel force transmission structure similar to a herringbone shape, which can not only greatly improve the rigidity of the handle mounting plate 2 and even the hidden handle mounting point, but also facilitate the handle mounting plate 2 to transfer the load received by the boss portion 212 and the supporting leg 22 to the door inner panel 300 respectively, thereby further improving the bearing capacity of the handle mounting plate 2.

[0048] Optionally, combined Figure 5 As shown, the support leg 22 further includes a flange portion 223 , which is extended along the edges of the second recessed portion 221 and the third recessed portion 222 and is located on the side of the second recessed portion 221 and the third recessed portion 222 facing the door outer panel.

[0049] In this embodiment, the flange portion 223 and the boss portion 212 are respectively convexly arranged on both sides of the second recessed portion 221, so that convex surfaces are formed on both sides of the second recessed portion 221, and the structure around the mounting portion 215 forms a concave-convex structural form, thereby further improving the rigidity of the structure around the handle mounting point.

[0050] Optionally, combined Figure 1 and Figure 2 As shown, the waistline reinforcement plate 1 includes a first reinforcement portion 11, a second reinforcement portion 12 and a third reinforcement portion 13 which are sequentially connected from top to bottom, and the first reinforcement portion 11 and the second reinforcement portion 12 are arranged at an obtuse angle or a right angle, and the third reinforcement portion 13 and the second reinforcement portion 12 are arranged at an obtuse angle or a right angle.

[0051] In this embodiment, the waistline reinforcement plate 1 is usually a bent plate structure, which is bent twice to form three roughly flat plate structures, namely the first reinforcement part 11, the second reinforcement part 12 and the third reinforcement part 13, wherein the first reinforcement part 11 and the second reinforcement part 12 are arranged at an obtuse angle or a right angle, which means that the surface where the first reinforcement part 11 is located and the surface where the second reinforcement part 12 is located are arranged at an obtuse angle or a right angle, and correspondingly, the third reinforcement part 13 and the second reinforcement part 12 are arranged at an obtuse angle or a right angle, which means that the surface where the third reinforcement part 13 is located and the surface where the second reinforcement part 12 is located are arranged at an obtuse angle or a right angle. When the handle mounting plate 2 is arranged below the waistline reinforcement plate 1, the mounting plate body 21 of the handle mounting plate 2 is usually welded to the third reinforcement part 13 of the waistline reinforcement plate 1, and when the handle mounting plate 2 is arranged above the waistline reinforcement plate 1, the mounting plate body 21 of the handle mounting plate 2 is usually welded to the first reinforcement part 11 of the waistline reinforcement plate 1. In this way, by arranging the first reinforcement part 11 and the third reinforcement part 13 above and below the second reinforcement part 12 respectively, and respectively arranging them at an obtuse angle or a right angle with the second reinforcement part 12, the waistline reinforcement plate 1 is made into a bending structure with a roughly Z-shaped cross-section, so as to greatly improve the rigidity of the waistline reinforcement plate 1.

[0052] Furthermore, combined with Figure 1 As shown, the waistline reinforcement plate 1 is provided with a second glue groove 14, and the waistline reinforcement plate 1 is used to be bonded to the door outer panel at the second glue groove 14. Specifically, the second glue groove 14 is provided on the third reinforcement portion 13, and a plurality of second glue grooves 14 are usually provided at intervals along the extension direction of the waistline reinforcement plate 1.
