[0034] See also Figures 1 to 8 Now, an embodiment of the plug-sliding door sealing frame installation and positioning device provided by the present invention is described. The plug-sliding door sealing frame installation and positioning device comprises a mounting member 100 and a bolt positioning member 200.

[0035] The mounting member 100, as a carrier of the bolt positioning member 200, can be a plate, a block or various profile structures. The mounting member 100 is used to be installed at the idle C-shaped slide groove 500 of the vehicle body. When the applicant was developing the plug door sealing frame installation and positioning device provided in the embodiment of the present invention, it was found that a bolt slide groove 600 was provided on the vehicle body. The bolt slide groove 600 is a C-shaped slide groove. At the same time, there is usually at least another C-shaped slide groove with other functions near the bolt slide groove 600. The C-shaped slide groove is usually connected or similar to the structure of the bolt slide groove 600 and is arranged side by side. However, the C-shaped slide groove may not be used to install the plug door sealing frame. Therefore, it is an idle C-shaped slide groove when installing the plug door sealing frame. The technical concept of this application is formally designed based on the function of exploring this idle C-shaped slide groove 500.

[0036] The mounting member 100 is provided with a first positioning and mounting unit 110 for plugging and positioning or clamping and positioning with the idle C-shaped chute 500, and a second positioning and mounting unit for positioning and installing the bolt positioning member 200. The first positioning and mounting unit 110 realizes the positioning and connection operation between the mounting member 100 and the idle C-shaped chute 500, and the second positioning and mounting unit is used for fast positioning and detachable installation of the bolt positioning member 200. Due to the special structure of the idle C-shaped chute 500, the first positioning and mounting unit 110 can be fast positioned and movably connected on the idle C-shaped chute 500 by clamping or plugging. The positions of the first positioning and mounting unit 110 and the second positioning and mounting unit on the mounting member 100 are designed in advance according to the positions of the sealing frame mounting bolts 700 required to be installed on the sealing frame.

[0037] The bolt positioning member 200 is detachably connected to the mounting member 100, and a bolt positioning notch 211 for positioning the sealing frame mounting bolt 700 is provided on the bolt positioning member 200. The bolt positioning member 200 has at least one, which can position one or more sealing frame mounting bolts 700, and the shape of the bolt positioning notch 211 is not limited, and can be a circular notch, a square notch, or a semi-enclosed notch that opens the edge of the bolt positioning member 200.

[0038] When using the plug sliding door sealing frame installation positioning device provided by the embodiment of the present invention, first use the first positioning installation unit 110 to position and install the installation member 100 at a preset position on the idle C-shaped slide 500; then the sealing frame installation bolt 700 to be installed can be slid into the bolt slide 600, and the bolt positioning member 200 can be quickly positioned and installed on the installation member 100 by using the second installation unit. After the bolt positioning member 200 is in place, the bolt positioning notch 211 is located near the bolt slide 600 (above or in front of the bolt slide 600), and the bolt positioning notch 211 of the bolt positioning member 200 is used to position each sealing frame installation bolt 700 to the corresponding position on the bolt slide 600; then the sealing frame can be installed. The entire positioning and installation process uses the idle C-shaped slide 500 to achieve the rapid positioning of the sealing frame installation bolt 700 in the bolt slide 600, thereby improving the installation efficiency. In addition, the plug sliding door sealing frame installation positioning device provided by the embodiment of the present invention has a light structure and can be operated independently by a single person.

[0039] Compared with the prior art, the Sierra door sealing frame installation and positioning device provided in the embodiment of the present invention, by providing a mounting piece that is plugged into or snapped into an idle C-shaped slide groove and a bolt positioning piece that is quickly positioned and installed with the mounting piece, can quickly position the sealing frame mounting bolts with the aid of an idle C-shaped slide groove, thereby improving the installation efficiency of the sealing frame and reducing manpower input; at the same time, the entire device has a simple and lightweight structure, and is installed at an idle C-shaped slide groove to avoid the device from bumping against the exterior paint of the vehicle body.

[0040] See also Figure 2 , Figure 3 , Figure 4 and Figure 6As a specific embodiment of the plug door sealing frame installation and positioning device provided by the present invention, the first positioning and installation unit 110 includes an insertion positioning block 111 for inserting into the idle C-shaped slide groove 500 and an abutment positioning portion 112 for abutting and positioning with the top end of the idle C-shaped slide groove 500. The plug-in positioning block 111 is adapted to the idle C-shaped slide groove 500, and can realize quick plug-in installation and pull-out disassembly with the idle C-shaped slide groove 500. The structure of the abutment positioning portion 112 is not limited and can be a plate, a block or other special-shaped structures. After the plug-in positioning block 111 is inserted into the idle C-shaped slide groove 500, the plug-in positioning block 111 can at least realize accurate positioning or approximate positioning of the mounting member 100 in the width direction of the mounting member 100 (not the extension direction and thickness direction of the mounting member 100) (because the sealing frame mounting bolt 700 slides in the bolt slide groove 600, the positioning requirement of the mounting member 100 in the width direction of the mounting member 100 is not high). At the same time, the positioning in the thickness direction of the mounting member 100 can be achieved by the abutment between the mounting member 100 itself and the idle C-shaped slide groove 500, or by the plugging of the plug-in positioning block 111 and the idle C-shaped slide groove 500. The abutting positioning portion 112 abuts against the end of the idle C-shaped slide groove 500 to achieve freedom-limiting positioning of the mounting member 100 in the third direction (the extension direction of the mounting member 100, generally also the length direction of the mounting member 100).

[0041] The plug-in positioning block 111 and the abutment positioning portion 112 are respectively connected to the mounting member 100. It should be pointed out here that the plug-in positioning block 111 and the abutment positioning portion 112 can be directly connected to the mounting member 100 respectively, or can be indirectly connected to the mounting member 100. For example, the abutment positioning portion 112 can be arranged on the plug-in positioning block 111, and the abutment positioning portion 112 is indirectly connected to the mounting member 100 with the aid of the plug-in positioning block 111.

[0042] The above structure can realize the rapid positioning and installation operation of the mounting member 100 and the idle C-shaped slide groove 500 in a simple and low-cost manner.

[0043] See also Figures 1 to 4 As a specific embodiment of the plug door sealing frame installation and positioning device provided by the present invention, the mounting member 100 is a strip structure, or a long strip plate structure. Because the idle C-shaped slide groove 500 and the bolt slide groove 600 are usually long, the mounting member 100 is designed as a lighter strip structure to facilitate single-person operation.

[0044] The plug-in positioning block 111 is located on one side surface in the thickness direction of the strip structure, and the abutting positioning portion 112 includes two block structures protruding from both sides of the plug-in positioning block 111 in the width direction of the strip structure. When installing the mounting member 100, the plug-in positioning block 111 is first inserted into the idle C-shaped slide groove 500, and then the abutting positioning portion 112 abuts against the top end of the idle C-shaped slide groove 500 to position the mounting member 100 in the length direction of the mounting member 100.

[0045] As a specific embodiment of the plug door sealing frame installation and positioning device provided by the present invention, the mounting piece 100 as a strip-shaped structure has one side surface in the thickness direction set as a special-shaped surface adapted to the sealing frame. The special-shaped surface depends on the external structure of the sealing frame and may be a combination of a partial plane and a partial arc surface.

[0046] See also Figures 1 to 8 As a specific embodiment of the plug-type door sealing frame installation positioning device provided by the present invention, the second positioning installation unit includes a positioning slot 120 plugged with the bolt positioning member 200. The positioning slot 120 is adapted to the outer edge of the bolt positioning member 200, and the bolt positioning member 200 can be quickly positioned on the mounting member 100 along the extension direction and thickness direction of the mounting member 100 by plugging (because the sealing frame mounting bolt 700 slides in the bolt slide groove 600, the positioning requirements for the mounting member 100 and the bolt positioning member 200 in the width direction of the mounting member 100 are not high). When positioning the sealing frame mounting bolt 700, first slide the sealing frame mounting bolt 700 in the bolt slide groove 600 to an approximate position corresponding to the positioning slot 120, and then insert the bolt positioning piece 200 into the positioning slot 120. The bolt positioning piece 200 (the bolt positioning notch 211) passes through the positioning slot 120 and extends to the top or front of the bolt slide groove 600. The bolt positioning notch 211 is used to realize the positioning of the sealing frame mounting bolt 700 in the extension direction of the bolt slide groove 600.

[0047] Typically, the positioning slots 120 correspond to the bolt positioning members 200 one by one, and one positioning slot 120 is used to position one bolt positioning member 200 .

[0048] See also Figure 2 , Figure 4 , Figure 7 and Figure 8As a specific embodiment of the plug door sealing frame installation positioning device provided by the present invention, the bolt positioning member 200 includes a plug plate 210 plugged into the positioning slot 120 and a positioning plate 220 for abutting and positioning against the side surface in the thickness direction of the mounting member 100. The plug plate 210 is vertically connected to the positioning plate 220, so that the plug plate 210 and the positioning plate 220 form a "T"-shaped structure. The bolt positioning notch 211 is provided on the plug plate 210. The positioning plate 220 can not only realize the positioning of the bolt positioning member 200 in the width direction of the mounting member 100, but also facilitates the operator's operation of inserting and removing the bolt positioning member 200.

[0049] See also Figure 2 , Figure 4 , Figure 7 and Figure 8 As a specific implementation of the plug door sealing frame installation positioning device provided by the present invention, the positioning slot 120 is a rectangular slot adapted to the shape of the plug plate 210.

[0050] See also Figure 2 and Fig. 9 As a specific embodiment of the plug-type sliding door sealing frame installation and positioning device provided by the present invention, the plug-type sliding door sealing frame installation and positioning device provided by the embodiment of the present invention also includes a rotating block 300 rotatably arranged on the mounting member 100, and by rotating to a certain angle range, the rotating block 300 can be inserted into or extended into the idle C-shaped slide groove 500.

[0051] As a bar-shaped mounting member 100, after one end (the first positioning mounting unit 110) is positioned and fixed with the idle C-shaped chute 500, because the mounting member 100 is relatively long and may have a certain degree of flexibility, the middle part and the other end of the mounting member 100 may have the problem of inaccurate positioning and fixing with the idle C-shaped chute 500. Therefore, a rotating block 300 is specially provided. After the rotating block 300 extends into the idle C-shaped chute 500, the rotating block 300 is rotated so that the rotating block 300 is abutted (or clamped) against the inner walls of both sides of the idle C-shaped chute 500, thereby further fixing the mounting member 100 with the mounting member 100.

[0052] See also Figure 2 and Fig. 9 As a specific embodiment of the plug door sealing frame installation and positioning device provided by the present invention, there are multiple rotating blocks 300, which are respectively arranged in the middle of the mounting member 100 or the other end away from the first positioning mounting unit 110.

[0053] See also Figure 2 and Fig. 9As a specific embodiment of the plug door sealing frame installation and positioning device provided by the present invention, the rotating block 300 is a quadrangular prism structure, specifically a tensile block structure with a parallelogram cross section. The two diagonals (or two adjacent sides) of the parallelogram can be of different lengths, so by changing the rotation angle, the tensile block structure with a parallelogram cross section can be extended into the idle C-shaped chute 500, and the tensile block structure (two diagonals) with a parallelogram cross section can be respectively abutted against the inner walls of the two sides of the idle C-shaped chute 500 by the rotation angle, so as to achieve the fixation of the rotating block 300 and the idle C-shaped chute 500.

[0054] See also Figure 2 and Fig. 9 As a specific embodiment of the plug door sealing frame installation and positioning device provided by the present invention, in order to facilitate the smooth abutment between the two diagonals of the stretching block structure with a parallelogram cross-section and the inner walls on both sides of the idle C-shaped slide groove 500, a transition arc corner structure 310 is arranged between the two adjacent side surfaces of the stretching block structure with a parallelogram cross-section, and the transition arc corner structure 310 is used to abut against the inner wall of the idle C-shaped slide groove 500.

[0055] See also Figures 1 to 4 and Fig. 9 As a specific embodiment of the plug-sliding door sealing frame installation and positioning device provided by the present invention, the plug-sliding door sealing frame installation and positioning device provided by the embodiment of the present invention also includes a bolt 400 threadedly connected to the mounting member 100, and specifically, the mounting member 100 is provided with a threaded hole threadedly connected to the bolt 400. The rotating block 300 is fixedly connected to the bolt 400, and the operator rotates the bolt 400 to realize the rotation operation of the rotating block 300 relative to the mounting member 100. The above structure is simple and reliable, and can realize the reliable fixation of the rotating block 300 and the inner wall of the idle C-shaped slide 500.
