Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle components, and in particular relates to a back door lock installation assembly and a vehicle. Background Art

[0002] The tailgate lock is a locking component that realizes the locking of the vehicle's tailgate. For a flip-up tailgate, the tailgate lock is usually installed in the cavity between the tailgate inner panel and the tailgate outer panel, and the locking end extends from the notch of the tailgate inner panel. Due to the large size and complex structure of the tailgate inner panel, a thin plate material with a relatively weak yield strength is generally used. In addition, due to the existence of the notch and the design requirement that the tailgate lock needs to be arranged based on the tailgate hinge axis, the tailgate inner panel around the tailgate lock needs to be designed with a larger drawing depth during manufacturing, and the molding process is more difficult. In addition, combined with the actual situation that the area where the tailgate lock is located is subject to greater force when the tailgate is opened and closed, it is easy to cause the area of ​​the tailgate inner panel near the tailgate lock to tear during the molding process and in the endurance condition of opening and closing. In order to improve this problem, a reinforcement plate is usually set between the tailgate inner panel and the outer panel, but this reinforcement plate still has similar defects as the tailgate inner panel, and the reinforcement effect is difficult to further improve. Utility Model Content

[0032] The tailgate lock generally includes a main lock body arranged on the vehicle body and a secondary lock body arranged on the tailgate. The inventor has found that during the opening process of the flip-up tailgate, the main lock body will have a certain obstructive effect on the secondary lock body, causing the area where the secondary lock body is located to be pulled. When closing the door, the secondary lock body will hit the main lock body to produce an impact effect. Repeated opening and closing of the door will cause the area where the secondary lock body is located to be repeatedly pulled and impacted, so the inner panel of the tailgate in this area is more prone to deformation and tearing.

[0033] In order to improve the problem that the back door inner panel 110 is easily deformed and torn, please refer to Figures 1 to 5 The back door lock installation assembly provided by the utility model is now described. The back door lock installation assembly includes a back door body 1 and a reinforcement bracket 2. The reinforcement bracket 2 is box-shaped, and its inner cavity can accommodate the back door lock 3. The reinforcement bracket 2 has a connecting plate 210 that is closely connected to the inner side of the back door body 1, and a surrounding plate 220 that is covered on the inner side of the connecting plate 210. The surrounding plate 220 is formed with a door lock installation position 201.

[0034] The back door lock installation assembly of this embodiment is applicable to both hatchback and three-box vehicles; the reinforcement bracket 2 is generally located at the lower part of the back door body 1, and the specific location corresponds to the locking position of the back door lock 3, which is mostly applicable to flip-up back doors. This embodiment exemplarily shows a three-box vehicle, and the reinforcement bracket 2 is located in the middle of the lower part of the back door body 1.

[0035] In this embodiment, the door lock installation position 201 is a hole position, and the connection between the back door lock 3 and the reinforcing bracket 2 is achieved through fasteners such as threaded connectors and clamps. This embodiment exemplarily shows the way of achieving connection through threaded connectors. In addition, in the reinforcing bracket 2, the connecting plate 210 and the enclosure 220 can be a plate structure with a continuous plate surface, or a plate structure with a hollow, groove and other structures, which can meet the requirements of assembly and reinforcement; in order to improve the strength and reduce the difficulty of manufacturing, this embodiment exemplarily shows the connecting plate 210 and the enclosure 220 as a plate structure with a continuous plate surface; of course, under the premise of having hollow or grooves, the hollow or grooves can be set to a triangle, trapezoidal and other structures to avoid affecting the overall strength of the reinforcing bracket 2.

[0036] Compared with the prior art, the tailgate lock installation assembly provided in this embodiment has the following beneficial effects: 1) The reinforcing bracket 2 is arranged outside the tailgate body 1 and forms a door lock installation position 201. The tailgate lock 3 is installed by means of the reinforcing bracket 2, thereby avoiding setting a notch on the tailgate inner panel 110, and there is no need to set a deep drawing area on the tailgate inner panel 110 that is compatible with the tailgate lock 3. In addition, the connecting plate 210 forms a multi-layer reinforcement on the tailgate inner panel 110, and the structural strength and rigidity of the tailgate inner panel 110 itself are effectively improved; 2) The reinforcing bracket 2 is a box-shaped structure, which has high structural strength and rigidity, and can provide sufficient accommodation and installation space for the tailgate lock 3, thereby meeting the assembly requirements of the tailgate lock 3. This embodiment provides a method for improving the integrity of the tailgate inner panel 110, reduces the drawing depth of the tailgate inner panel 110, and combines the box-shaped structure design of the reinforcement bracket 2 itself, so that the overall structural strength and rigidity of the tailgate lock 3 installation area are significantly improved, and the reliability of use is greatly increased. Compared with the traditional reinforcement structure, the tailgate lock installation assembly of this embodiment significantly improves the reinforcement effect of the tailgate lock 3 installation area, avoiding the problem of long-term cracking of the tailgate inner panel 110 and the reinforcement structure; and the drawing depth is reduced during molding, so that the molding process is improved, avoiding the problem of cracking of the tailgate inner panel 110 during the molding process.

[0037] In some specific embodiments of the enclosure 220 not shown in the figures, the enclosure 220 includes a top plate 221, a first connecting plate 222, a bottom plate 223 and a second connecting plate 224 connected in sequence end to end along the circumference of the connecting plate 210, and also includes a cover plate connected to the inner edges of the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224. The top plate 221 is located at the upper edge of the connecting plate 210, and the bottom plate 223 is located at the lower edge of the connecting plate 210. At least one of the top plate 221, the first connecting plate 222, the bottom plate 223, the second connecting plate 224 and the cover plate forms a door lock installation position 201. In this embodiment, the enclosure 220 cooperates with the connecting plate 210 to form a closed box structure, and the door lock installation position 201 can be separately set on one of the top plate 221, the first connecting plate 222, the bottom plate 223, the second connecting plate 224 and the cover plate, or, in the case of multiple door lock installation positions 201, multiple door lock installation positions 201 are dispersedly set on different plates. The specific setting method is related to the structure and locking requirements of the back door lock 3, and is not limited here. It should be noted that the extension trend of the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224 is consistent with the circumferential contour of the connecting plate 210, that is, the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224 can be straight plates, or multi-section bent plates, arc-shaped plates, etc., which are not limited here.

[0038] In specific implementation, the top plate 221, the first connecting plate 222, the bottom plate 223, the second connecting plate 224, the cover plate and the connecting plate 210 are enclosed to form an inner cavity capable of accommodating the back door lock 3. During assembly, the top plate 221, the first connecting plate 222, the bottom plate 223, the second connecting plate 224 and the connecting plate 210 can be first connected in place to form the main body of the box structure. After the back door lock 3 is installed and fixed in the main body of the box structure, the cover plate is then covered and fixed in place. The cover plate can be integrally bent and formed with one of the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224. When the back door lock 3 is installed, the cover plate is opened. After the back door lock 3 is installed, the cover plate is bent and covers the inner opening of the box structure. Then, it can be connected and fixed with the other three side plates by means of detachable connection such as snap connection, so as to facilitate the maintenance and replacement of the back door lock 3 in the later stage.

[0039] See also Figures 1 to 4 In other specific embodiments of the enclosure 220, the enclosure 220 includes a top plate 221, a first connecting plate 222, a bottom plate 223 and a second connecting plate 224 which are connected in sequence end to end along the circumferential direction of the connecting plate 210, the top plate 221 is located at the upper edge of the connecting plate 210, the bottom plate 223 is located at the lower edge of the connecting plate 210, and at least one of the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224 forms a door lock installation position 201, wherein the top plate 221, the first connecting plate 222, the bottom plate 223, the second connecting plate 224 and the connecting plate 210 enclose an inner cavity that can accommodate the back door lock 3 and is open on the inner side. It should be noted that the extension trend of the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224 is consistent with the circumferential profile of the connecting plate 210, that is, the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224 can be straight plates, or multi-section bent plates, arc-shaped plates, etc., which are not limited here. The door lock installation position 201 of this embodiment can be set separately on one of the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224, or, when there are multiple door lock installation positions 201, multiple door lock installation positions 201 are dispersedly set on different plates. The specific setting method is related to the structure and locking requirements of the back door lock 3, which is not limited here. Since the enclosure 220 cooperates with the connecting plate 210 to form a box structure with an open inner side, it can not only effectively accommodate the back door lock 3, but also the reinforcing bracket 2 can avoid obstruction to the back door lock 3 when loading and unloading the back door lock 3, making it convenient for disassembly and assembly; since the inner side of the back door inner plate 110 is also covered with a back door interior panel, whether the inner side of the reinforcing bracket 2 is open will not affect the interior effect. It should be understood that the top plate 221, the first connecting plate 222, the bottom plate 223 and the second connecting plate 224 are reinforced on the rear side of the connecting plate 210, which can make the reinforcing bracket 2 have a higher structural strength and rigidity as a whole.

[0040] Based on the above embodiments, see Figures 1 to 4 The inner and outer widths of the bottom plate 223 are greater than the inner and outer widths of the top plate 221. The bottom plate 223 is provided with a position-avoiding notch 2231 corresponding to the back door lock 3, and a door lock installation position 201. The door lock installation position 201 and the position-avoiding notch 2231 are staggered left and right, and the position-avoiding notch 2231 has an inward opening. In this embodiment, in order to meet the general installation requirements of the back door lock 3 and ensure that the back door lock 3 is evenly stressed after closing, the back door lock 3 is installed on the bottom plate 223. The bottom plate 223 with a larger inner and outer width can provide sufficient installation space for the back door lock 3 (that is, provide sufficient layout time for the door lock installation position 201) to ensure the reliability of the installation, while the narrower top plate 221 provides more operating space for the installation of the back door lock 3 in the up and down directions, which is not only convenient for installation, but also saves materials. Based on this, in order to compress the assembly dimensions of the tailgate lock 3 and the reinforcing bracket 2 in the inward and outward directions, a avoidance notch 2231 is provided to accommodate the main structure of the tailgate lock 3. Since the opening of the avoidance notch 2231 is inward, when the tailgate lock 3 is installed, the main body of the tailgate lock 3 can be directly placed into the avoidance notch 2231 from the opening side of the avoidance notch 2231, thereby avoiding interference of the bottom plate 223 with the loading and unloading of the tailgate lock 3, thereby ensuring the convenience of loading and unloading.

[0041] In some more specific embodiments, in order to ensure uniform force, multiple door lock installation positions 201 are provided, and the multiple door lock installation positions 201 are symmetrically arranged on the left and right sides of the avoidance gap 2231. This embodiment exemplarily shows an implementation method in which two door lock installation positions 201 are provided, and the two door lock installation positions 201 are symmetrically arranged on the left and right sides of the avoidance gap 2231.

[0042] For more details, see Figures 1 to 4 The arrangement of the avoidance opening weakens the structural strength of the bottom plate 223 to a certain extent. To offset this defect, the edge of the avoidance notch 2231 is bent downward to form a reinforcing flange 2232. During installation, the back door lock 3 is first overlapped on the top of the bottom plate 223 and then fixed with fasteners. The reinforcing flange 2232 will not affect the installation of the back door lock 3, and at the same time, it can also make the bottom plate 223 have a certain pre-positioning effect, further improving the convenience of assembling the back door lock 3.

[0043] In some embodiments, see Figures 1 to 4 The inner and outer widths of the first connecting plate 222 and the second connecting plate 224 gradually decrease from bottom to top, so that the first connecting plate 222 and the second connecting plate 224 have a trapezoidal structure that is narrow at the top and wide at the bottom. The trapezoid has the characteristic of high structural stability, and the bending strength of the first connecting plate 222 and the second connecting plate 224 themselves is improved, thereby promoting the improvement of the overall structural strength and rigidity of the reinforcing bracket 2.

[0044] Based on the above embodiments, see Figures 1 to 4 The inner contour lines of the first connecting plate 222 and the second connecting plate 224 are arc lines protruding outward, so that the first connecting plate 222 and the second connecting plate 224 form an arch structure, further improving the load-bearing capacity in the inner and outer directions.

[0045] It should be noted that the first connecting plate 222 and the second connecting plate 224 are arranged along the left-right direction. The first connecting plate 222 can be on the left side of the second connecting plate 224, or the first connecting plate 222 can be on the right side of the second connecting plate 224, and there is no sole limitation here; in addition, the structures of the first connecting plate 222 and the second connecting plate 224 are roughly the same, so that the overall reinforcing bracket 2 presents a left-right symmetrical structure, which is also beneficial to enhancing its structural strength.

[0046] In some embodiments, see Figures 1 to 4 In order to facilitate molding, the first connecting plate 222 and the top plate 221, the second connecting plate 224 and the top plate 221, the first connecting plate 222 and the bottom plate 223, and the second connecting plate 224 and the bottom plate 223 are all overlapped and fixed. In specific implementation, the first connecting plate 222 and the second connecting plate 224 both have a top plate 221 flange overlapped with the top plate 221, and a bottom plate 223 flange overlapped with the bottom plate 223, and the door lock installation position 201 corresponds to the bottom plate 223 flange setting.

[0047] More specifically, the top plate 221 , the bottom plate 223 , the connecting plate 210 , the first connecting plate 222 and the second connecting plate 224 are all bent and formed integrally, thereby reducing the seams of the reinforcing bracket 2 and further improving its structural strength and rigidity.

[0048] In some embodiments, see Figures 1 to 5 The back door body 1 includes a back door inner panel 110 and a back door outer panel 120 disposed outside the back door inner panel 110. In order to further compress the space occupied by the reinforcing bracket 2 in the inner and outer directions and prevent the reinforcing bracket 2 from affecting the overall thickness of the back door, the back door inner panel 110 has an outwardly recessed avoidance space 1101. The reinforcing bracket 2 is disposed in the avoidance space 1101, and the connecting plate 210 is fitted and connected to the outer wall of the avoidance space 1101. The drawing depth of the recessed avoidance space 1101 is less than the drawing depth of the corresponding area of ​​the conventional back door inner panel 110. The wall surface of the avoidance space 1101 is a continuous surface, preferably without a notch or hole structure.

[0049] For more details, see Figure 5 The bottom of the avoidance space 1101 is open to reserve an installation operation space corresponding to the bottom plate 223.

[0050] In some embodiments, see Figure 3 and Figure 6 The back door body 1 includes a back door inner panel 110, a support plate 130 and a back door outer panel 120 which are arranged sequentially from the inside to the outside, and the connecting plate 210 is fitted and connected to the inner side surface of the back door inner panel 110; the support plate 130 has an inner connecting portion 131, a supporting portion 132 and an outer connecting portion 133 which are connected sequentially from the inside to the outside, wherein the inner connecting portion 131 is fitted and connected to the back door inner panel 110, and the connecting area corresponds to the connecting plate 210, and the outer connecting portion 133 is fitted and connected to the back door outer panel 120. The support plate 130 forms a support between the tailgate inner panel 110 and the tailgate outer panel 120, ensuring the structural strength of the tailgate lock 3 installation area in the inward and outward directions. When opening and closing the door, the pulling or impact force transmitted by the tailgate lock 3 can be dispersed and transmitted through the force transmission path from the reinforcing bracket 2, the tailgate inner panel 110, the support plate 130 to the tailgate outer panel 120, thereby achieving the effect of quickly dispersing the force to multiple components, avoiding the problem of deformation and cracking of the tailgate inner panel 110 due to concentrated force. At the same time, the higher structural strength can also dissipate the action energy as quickly as possible, reducing the risk of structural damage.

[0051] On the basis of the above-mentioned embodiment, the inner connection part 131 and the outer connection part 133 extend to both sides of the support part 132 respectively, so that the support plate 130 is in a Z-shaped structure as a whole, with a large operating space during installation and high structural strength, and the force of the back door inner plate 110 can be transmitted through the path from the inner connection part 131 and the support part 132 to the outer connection part 133.
