[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] Embodiment 1

[0035] This embodiment relates to a rear door lock reinforcement structure, which can improve the structural stability of the rear door lock installation part of the rear door; an exemplary structure thereof is as follows Figure 1 , Figure 2 and Figure 3 shown.

[0036] In general, the rear door lock reinforcement structure includes a reinforcement plate 2 arranged on the inner plate 4 of the rear door corresponding to the rear door lock, and support plates 1 respectively arranged on the left and right sides of the reinforcement plate 2. The bottom of the support plate 1 is fixedly connected to the reinforcement plate 2, and the upper part of the support plate 1 is abutted and connected to the outer plate 3 of the rear door.

[0037] In view of the fact that a support plate 1 is provided on each of the left and right sides of the reinforcing plate 2, the support plate 1 naturally includes the following: Figure 2 The left support plate 1a and the right support plate 1b shown in the figure; the left support plate 1a and the right support plate 1b can of course adopt different structural forms, or adopt the same structure and be arranged in the same direction and posture. However, preferably, the left support plate 1a and the right support plate 1b of this embodiment adopt the same structure and are arranged in a bilaterally symmetrical manner. When introducing the support plate 1 below, only the left support plate 1a is used as an example; the structure of the right support plate 1b is symmetrical with the left support plate 1a, and the structural setting of the left support plate 1a can be referred to, and will not be described separately.

[0038] like Figure 2 and Figure 3 As shown, the reinforcing plate 2 of this embodiment includes a base plate 20, and a front flange 21 and a rear flange 22 respectively bent and formed at the front and rear ends of the base plate 20; the base plate 20 and the front flange 21 are both overlapped on the inner plate 4, and the rear flange 22 is abutted and connected with the outer plate 3. By respectively arranging the front flange 21 and the rear flange 22 at the front and rear ends of the reinforcing plate 2, the overlap area between the reinforcing plate 2 and the inner plate 4, and between the reinforcing plate 2 and the outer plate 3 can be increased, thereby increasing the structural reinforcement effect of the reinforcing plate 2.

[0039] In addition, it is preferred that an upwardly protruding boss 23 is formed at the edge of both the left and right sides of the base plate 20, and the bottom of the support plate 1 is at least partially fixed to the boss 23 on the corresponding side. Providing the protruding boss 23 at the edge of the base plate 20 can enhance the structural support of the portion, thereby providing a more stable support base for the support plate 1.

[0040] The above-mentioned base plate 20 can of course adopt a flat plate structure, but in this embodiment, a first recessed groove 24 is formed in the middle of the base plate 20, and an escape hole 200 for avoiding the lock tongue of the back door lock is opened on the plate body at the bottom of the first recessed groove 24. A first mounting hole 201 is respectively provided on both sides of the escape hole 200 for mounting the back door lock. The recessed groove structure formed on the base plate 20 is conducive to enhancing the overall structural strength of the base plate 20.

[0041] There are of course many design options for the structural form of the support plate 1; for example, a simple bending structure can be used. Figure 4 , Figure 5As shown, the support plate 1 includes a plate body 10 arranged perpendicular to the left-right direction of the vehicle, and a notch 12 is provided at the bottom of the plate body 10; the parts of the plate body 10 located on both sides of the notch 12 respectively constitute legs 101, and the bottoms of the two legs 101 are fixedly connected to the reinforcing plate 2. At the same time, a plurality of second mounting holes 102 can also be provided on the plate body 10 for mounting and fixing the rear door lock.

[0042] The bottom of the support plate 1 is designed as a double-leg support structure, which can adapt to the complex surface characteristics of the reinforcing plate 2 and form a triangular support form between the support plate 1 and the reinforcing plate 2. In this embodiment, the notch 12 is triangular in shape, and the two legs 101 are distributed in a "human" shape, which greatly improves the support stability of the support plate 1 on the reinforcing plate 2. The setting of the notch 12 is also conducive to reducing the weight of the support plate 1 itself.

[0043] Figure 5 The three-dimensional structure of the left support plate 1a is shown. As can be seen from the figure, an upper flange 14 is formed on one side of the upper part of the plate body 10 of the left support plate 1a of this embodiment, and the same design is adopted on the right support plate 1b. In this way, the support plate 1 is abutted against the outer plate 3 through the upper flange 14. The upper flange 14 is arranged on the upper part of the support plate 1, which can increase the abutment area between the support plate 1 and the outer plate 3, and the support position and height of the support plate 1 can also be flexibly adjusted according to the specific situation of the outer plate 3. The stable support of the upper flange 14 to the outer plate 3 can not only strengthen the overall installation foundation of the back door lock; but also improve the rigidity of the outer plate 3, thereby improving the structural stability of the car license plate installation area, and improving the vibration problem of the license plate area when the back door is closed. As for the bending direction of the upper flange 14, of course, it can be flexibly selected, and it can be bent toward the left or right side of the support plate 1. It is best to make the upper flange 14 closer to the weak position on the outer plate 3.

[0044] In addition, the rear end of the reinforcing plate 2 of this embodiment is provided with a glue groove 5, and the glue groove 5 is filled with expansion glue, and the reinforcing plate 2 is bonded to the outer plate 3 by the expansion glue; when the rear end of the reinforcing plate 2 is provided with a rear flange 22, the glue groove 5 can be provided on the rear flange 22. Similarly, the upper flange 14 of this embodiment is provided with a glue groove 5, and the glue groove 5 is filled with expansion glue, and the support plate 1 is bonded to the outer plate 3 by the expansion glue.

[0045] By filling the expansion glue in the glue groove 5, the connection reliability between the support plate 1 and the outer plate 3 can be further enhanced, and the expansion glue has a certain buffering effect between the support plate 1 and the outer plate 3, which can further improve the vibration of the car license plate when the back door is closed, thereby eliminating the problem of the license plate vibrating and producing a tremor when the back door is closed. In this embodiment, based on the fact that the rear end of the reinforcing plate 2 is provided with a rear flange 22, it is preferred to set the glue groove 5 on the rear flange 22, and at the same time, set the glue groove 5 on the upper flange 14.

[0046] like Figure 5 Combined with Figure 6 As shown, a second sink 100 is formed on the plate body 10 of this embodiment, and a notch 12 is provided at the bottom of the second sink 100. In addition, a reinforcing flange 120 may be provided at the edge of the notch 12 of the plate body 10. The structure of providing the second sink 100 on the plate body 10 can enhance the structural strength of the plate body 10; providing the reinforcing flange 120 at the edge of the notch 12 can also achieve the effect of enhancing the structural strength of the support plate 1 and improving the structural stability of the leg 101. Of course, the above-mentioned second sink 100 and reinforcing flange 120 can be provided selectively or both; the depth of the second sink 100 and the structural dimensions of the reinforcing flange 120 can be reasonably set. In this embodiment, not only a second trough 100 is provided, but also a reinforcing flange 120; wherein, the reinforcing flange 120 is sunken relative to the bottom surface of the second trough 100, and the distance b between the surface of the reinforcing flange 120 and the bottom surface of the second trough 100 (i.e., the depth of the reinforcing flange 120) can be set at about 3 mm; the depth a of the second trough 100 is preferably set between 3 mm and 5 mm.

[0047] In addition, in this embodiment, the bottom of the two legs 101 is formed with a lower flange 13, which is overlapped on the reinforcing plate 2 and welded to the reinforcing plate 2. The setting of the lower flange 13 can greatly increase the connection area between the support plate 1 and the reinforcing plate 2, which is conducive to enhancing the connection stability between the two. There are of course many options for the specific structural form of the lower flange 13. In this embodiment, the lower flange 13 located on the front side of the support plate 1 is correspondingly connected between the base plate 20 and the front flange 21 of the reinforcing plate 2, and the lower flange 13 includes a bottom 130 and a side 131 connected by bending, the bottom 130 is overlapped on the base plate 20, and the side 131 is overlapped on the front flange 21; the bending shape of the bottom 130 and the side 131 can be set according to the bending shape of the front flange 21; the angle between the two profiles of the bottom 130 and the side 131 of this embodiment is 95°. The lower flange 13 at the rear side of the support plate 1 is in the shape of a flat plate, and the lower flange 13 overlaps the boss 23 at the edge of the base plate 20. The welding method between the two lower flanges 13 and the reinforcing plate 2 can be spot welding or full welding. Considering that the space where the reinforcing plate 2 is located is small and the welding space is insufficient, plug welding technology can also be used (two plates are connected up and down, and the two plates are welded through by melting welding to achieve fixed connection).

[0048] To summarize, the rear door lock reinforcement structure of the present embodiment provides a reinforcement plate 2 on the inner panel 4 of the rear door corresponding to the installation position of the rear door lock, and provides a support plate 1 on each of the left and right sides of the reinforcement plate 2, and the bottom of the support plate 1 is fixedly connected to the reinforcement plate 2, and the upper part of the support plate 1 is abutted against the outer panel 3, so that a stable support can be formed between the outer panel 3 and the inner panel 4, providing a good installation foundation for the installation of the rear door lock, and also helping to enhance the structural performance of the car license plate installation area on the rear door, thereby improving the structural stability of the rear door lock installation part of the rear door.
