[0033] Reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, proposes

[0034] A novel back door limit block assembly includes:

[0035] A first mounting seat 1, used for being arranged on a vehicle body, and having a plurality of slide grooves 2;

[0036] The second mounting seat 3 is used to be set on the tailgate of the vehicle. The second mounting seat 3 has a plurality of sliding protrusions 4, and the cross-sectional size of the opening of the slide groove 2 and the cross-sectional size of the sliding protrusion 4 gradually decrease from the starting end to the end of the slide groove 2. The sliding protrusion 4 is used to be slidably set in the slide groove 2.

[0037] In this embodiment, since the first mounting seat 1 of the existing tailgate limit block has a slide groove 2 and the second mounting seat 3 has a sliding protrusion 4, when the tailgate is closed, the first sliding protrusion 4 slides into the slide groove 2 with a poor positioning effect and poor stability. The present scheme is provided with a first mounting seat 1 and a second mounting seat 3, and both the sliding protrusion 4 and the slide groove 2 have a plurality of sliding protrusions 4, and the plurality of sliding protrusions 4 are respectively and one by one arranged in a plurality of slide grooves 2, which can increase the stability of the cooperation between the first mounting seat 1 and the second mounting seat 3, and can increase the positioning effect of the cooperation between the first mounting seat 1 and the second mounting seat 3, thereby improving the stability of the installation.

[0038] Further, the second mounting seat 3 has an abutting end 5, the abutting end 5 has a mounting hole 6, and further includes:

[0039] The buffer block 7 is arranged on the mounting hole 6 .

[0040] In this embodiment, the second mounting seat 3 has an abutment end 5, and a buffer block 7 is installed in the mounting hole 6 of the abutment end 5. The buffer block 7 can achieve a buffering effect in the matching process of the first mounting seat 1 and the second mounting seat 3, thereby further improving the stability of the matching between the first mounting seat 1 and the second mounting seat 3.

[0041] Furthermore, the buffer block 7 has a clamping end 8 which is clamped into the mounting hole 6 and is in a frustum shape.

[0042] In this embodiment, since the limit block 7 is impacted each time the tailgate is opened or closed, it is easy to be damaged and needs to be replaced regularly. The limit block of this solution is configured to be detachable, and the clamping end 8 of the limit block is configured to be frustum-shaped. When installation is required, the frustum-shaped clamping end 8 is easy to install and is not easy to fall off, thereby realizing quick replacement of the buffer block 7 and reducing the use cost of the device.

[0043] Further, the sliding protrusion 4 has a buffer groove 9, the second mounting seat 3 has a mounting cavity 10, the buffer groove 9 and the mounting cavity 10 are connected, the end width of the sliding protrusion 4 is greater than the end width of the sliding groove 2, and further includes:

[0044] The flexible block 11 is arranged in the installation cavity 10 .

[0045] In this embodiment, the sliding protrusion 4 has a buffer groove 9, and the second mounting seat 3 also has an installation cavity 10. A flexible block is arranged in the installation cavity 10. When the sliding protrusion 4 slides into the sliding groove 2, the flexible blocks are squeezed toward the installation groove position on both sides of the sliding protrusion 4, which can further realize the stability of the cooperation between the first mounting seat 1 and the second mounting seat 3.

[0046] Furthermore, the first mounting seat 1 has a plurality of first sunken platforms 12, each of which has a first mounting groove 13, which is connected to the vehicle body through a fixing member, and the second mounting seat 3 has a plurality of second sunken platforms 14, each of which has a second mounting groove 15, which is connected to the tailgate through a fixing member.

[0047] In this embodiment, the first mounting seat 1 has a first sunken platform 12, the second mounting seat 3 has a second sunken platform 14, the first sunken platform 12 has a first mounting groove 13, the second sunken platform 14 has a second mounting groove 15, the first mounting groove 13 and the second mounting groove 15 are used to install the first mounting seat 1 and the second mounting seat 3 respectively, the first sunken platform 12 and the second sunken platform 14 are used to avoid contact between the first mounting seat 1 and the second mounting seat 3, the first mounting groove 13 and the second mounting groove 15 can be adjusted to match the mounting holes 6 on the vehicle body and the tailgate to avoid installation failure due to production errors.

[0048] Furthermore, the flexible block 11 has extrusion protrusions 16 on both sides, and the extrusion protrusions 16 are disposed against the side walls of the installation cavity 10 .

[0049] In this embodiment, the flexible block has extrusion protrusions 16 on both sides. Under the action of the extrusion protrusions 16, the flexible block is interference-set in the installation cavity 10 to prevent the flexible block from falling out of the installation cavity 10 during use.

[0050] Furthermore, it also includes:

[0051] There are a plurality of bushings 17 , and the bushings 17 are respectively disposed in the first mounting groove 13 and the second mounting groove 15 .

[0052] In this embodiment, matching bushings 17 are disposed in the first installation groove 13 and the second installation groove 15 to seal and prevent the first installation groove 13 and the second installation groove 15 from being worn and aged.

[0053] Furthermore, the first mounting groove 13 is a round hole, and the second mounting groove 15 is an oblong hole.

[0054] In this embodiment, the second mounting groove 15 is configured as an oblong hole to avoid inaccurate positioning due to processing errors, which may result in failure to set the first mounting seat 1 or the second mounting seat 3 on the vehicle body and the tailgate.

[0055] Furthermore, the buffer groove 9 divides the sliding protrusion 4 into a movable end 19 and a fixed end 18 . After the sliding protrusion 4 slides into the sliding groove 2 , the movable end 19 is close to the fixed end 18 .

[0056] In this embodiment, the sliding protrusion 4 is divided into a movable end 19 and a fixed end 18. When the sliding protrusion 4 slides into the slide groove 2, the sliding end is close to the fixed end 18 to achieve a better buffering effect and improve the stability of the cooperation between the sliding protrusion 4 and the slide groove 2.

[0057] Furthermore, the buffer block 7 is made of rubber, and the flexible block 11 is made of polyurethane.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
