DETAILED DESCRIPTION

[0026] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0027] As shown in Figure 1 , Figure 2 and Figure 7 , a guide rail end cover 1 of the preferred embodiment of the present application is installed at the end of a door guide rail 2, and the vehicle body sheet metal 3 parallel to the mounting surface 21 of the door guide rail 2 is provided with a mounting hole 31, the vehicle body sheet metal 3 and the door guide rail 2 are fixedly connected, and the guide rail end cover 1 comprises a main body 11, a mounting buckle 12, a first limiting plate 13, and a second limiting plate 14.

[0028] The main body 11 is a quadrilateral structure, and the plane where the main body 11 is located is parallel to the mounting surface 21 of the guide rail. The first limiting plate 13 and the second limiting plate 14 are respectively fixedly connected with the main body 11, and the first limiting plate 13 and the second limiting plate 14 are clamped at the two side surfaces 23 of the door guide rail 2. The trailing end 122 of the mounting buckle 12 is detachably connected with the main body 11, and the leading end 121 of the mounting buckle 12 is matched with the mounting hole 31.

[0029] By the above scheme, the edge of the main body 11 extends out of the limiting plate to clamp the side surface 23 of the door guide rail 2, thereby reducing the shaking and displacement of the guide rail end cover 1, and the mounting hole 31 is arranged, and the mounting hole 31 cooperates with the buckle to fix the guide rail end cover 1 at the end of the guide rail, thereby preventing the guide rail end cover 1 from falling off the guide rail. Since the installation buckle 12 has a lower cost than the nut and bolt, the production cost can be reduced, and meanwhile, the installation of the installation buckle 12 only needs one person to press, thereby reducing the assembly time and the requirement for the number of assembly personnel.

[0030] In order to make the installation more reliable, in an embodiment, as shown in Figure 3 、 Figure 4 and Figure 5 , the second limiting plate 14 is provided with a first limiting buckle 141, the first limiting buckle 141 includes a first cantilever 1411 and a first hook 1412, the first cantilever 1411 is integrally formed with the second limiting plate 14, and the first hook 1412 hooks the guide rail to make the first cantilever 1411 abut against the side surface 23; the main body 11 is provided with a second limiting buckle 111, the second limiting buckle 111 includes a second cantilever 1111 and a second hook 1112, and the second hook 1112 hooks the mounting surface 21 to make the second cantilever 1111 abut against the end surface 22 of the guide rail.

[0031] It can be understood that since the first cantilever 1411 is integrally formed with the second limiting plate 14, it can also be understood that the first limiting buckle 141 includes the first hook 1412, and the first hook 1412 extends out of the second limiting plate 14. The second limiting plate 14 is used as the first cantilever 1411.

[0032] The first hook 1412 and the second hook 1112 can hook the guide rail, thereby strengthening the assembly strength and further reducing the probability of the guide rail end cover 1 falling out of the mounting hole 31. Since the first cantilever 1411 abuts against the side surface 23 and the second cantilever 1111 abuts against the end surface 22 of the guide rail, the guide rail end cover 1 can be limited in two directions of the side surface 23 and the end surface 22, thereby preventing the guide rail end cover 1 from rotating along the mounting hole 31.

[0033] Since the operation space at the position of the end of the door guide rail 2 may be insufficient, in an embodiment, as shown in Figure 2 , the mounting surface 21 of the door guide rail 2 can also be provided with a positioning hole 25; and the guide rail end cover 1 can also include a positioning pin 16. The positioning pin 16 is integrally formed with the main body 11, the positioning pin 16 extends out of the main body 11 along the extension direction, and the positioning pin 16 is used for being inserted into the positioning hole 25.

[0034] The operation space is insufficient, and the operator cannot directly and clearly see the installation position, which may result in "blind operation". Through the cooperation of the positioning pin 16 and the positioning hole 25, the guide rail end cover 1 can be correctly installed in place during blind operation. Through the cooperation of the positioning pin 16 and the positioning hole 25, a precise "positioning guide" is provided for the installation operation. Even under the condition of blind operation where the specific installation situation cannot be seen, the guide rail end cover 1 can still be correctly installed at the position where it should be, greatly improving the accuracy and efficiency of the installation.

[0035] At the same time, since the positioning pin 16 and the installation buckle 12 both extend into the installation surface 21 of the guide rail, the cooperation of the positioning pin 16 and the installation buckle 12 can reduce the shaking of the guide rail end cover 1 along the installation surface 21 of the guide rail, thereby reducing the gap caused by the shaking.

[0036] In addition to the gap caused by the shaking, there may also be a fitting gap caused by thermal expansion and contraction of the material, deformation, machining precision, and the like.

[0037] In order to compensate for these deficiencies and prevent a gap from being generated between the guide rail end cover 1 and the door guide rail 2, as shown in Figure 6 In an embodiment, the inner side of the first limiting plate 13 is provided with a plurality of ribs 131. When the guide rail end cover 1 is installed at the end of the door guide rail 2, the plurality of ribs 131 are in contact with the side surface 23 of the guide rail, which is used to reduce the installation gap between the first limiting plate 13 and the side surface 23 of the door guide rail 2.

[0038] By adding a plurality of ribs 131 to the inner side of the first limiting plate 13, the plurality of ribs 131 can be in contact with the side surface 23 of the guide rail when the guide rail end cover 1 is installed at the end of the door guide rail 2. Therefore, the clamping force can be further improved, the deficiency of the machining precision can be compensated for, and the assembly gap between the first limiting plate 13 and the door guide rail 2 can be eliminated.

[0039] Since the first limiting plate 13 is arranged opposite to the second limiting plate 14, the assembly gap between the first limiting plate 13 and the door guide rail 2 is eliminated, and the assembly gap between the second limiting plate 14 and the door guide rail 2 is also eliminated.

[0040] It can be understood that in the present application, the detachable connection between the tail end 122 of the installation buckle 12 and the main body 11 can adopt threaded connection (such as providing a threaded hole on the main body 11, and processing the tail end 122 of the installation buckle 12 into a thread), buckle connection, plug-in connection (maintaining the connection through the friction force of interference fit), or hinge connection. The tail end 122 of the installation buckle 12 is first detachably assembled with the main body 11, and then installed at the end of the door guide rail 2, which can be completed by one person.

[0041] In an embodiment of the present application, as shown in Figure 6 andFigure 7 As shown, the main body 11 is provided with a sliding groove 112, and the tail end 122 is in sliding connection with the sliding groove 112. The tail end 122 is provided with a radial protrusion 123, which is used to prevent the mounting buckle 12 from being pulled out of the sliding groove 112.

[0042] Through the structure of the sliding groove 112 and the radial protrusion 123, the mounting buckle 12 can be conveniently disassembled and assembled, and the radial protrusion 123 makes it difficult for the mounting buckle 12 to be pulled out of the sliding groove 112, thereby improving the anti-pulling-out effect and the durability of the guide rail end cover 1.

[0043] In another embodiment, the guide rail end cover 1 can further include a third limiting plate 15 fixedly connected with the main body 11. The first limiting plate 13 and the third limiting plate 15 are connected through a rounded corner, and the third limiting plate 15 and the second limiting plate 14 are connected through a rounded corner.

[0044] In mechanical structures, when there are sharp corners between adjacent components, stress concentration phenomena are easy to occur, and stress concentration often becomes a hidden danger point for structural damage, fatigue cracks, and other problems. By connecting any two adjacent limiting plates through a rounded corner, stress concentration caused by sharp corners can be effectively avoided, making the force transmitted more uniformly and gently in the structure, thereby improving the strength and fatigue resistance of the entire limiting plate structure, prolonging its service life, and ensuring more reliable limiting function during long-term use.

[0045] As shown in Figure 4 and Figure 7 In an embodiment, the connecting portion of the positioning pin 16 and the main body 11 is provided with a plurality of reinforcing ribs 113. The reinforcing ribs 113 can enhance the structural strength of the connecting portion of the positioning pin 16 and the main body 11, and reduce the possibility of deformation or fracture.

[0046] In another embodiment, the guide rail end cover 1 can further include a support plate 17, which is in abutment with the door guide rail 2. The support plate 17 extends from the side of the main body 11 covered by the mounting surface 21, and the extension direction of the support plate 17 is the same as that of the first limiting plate 13.

[0047] After the mounting buckle 12 is installed in the mounting hole 31, there can be a certain installation gap. Through the above-mentioned scheme, since the side where the support plate 17 is located is covered by the mounting surface 21 of the door guide rail 2, the support plate 17 abuts against the other side of the mounting surface 21 of the door guide rail 2, thereby cooperating with the first hook 1412 and the second hook 1112 to limit the shaking along the extension direction, and the deficiency of the mounting buckle 12 structure is overcome.

[0048] In an embodiment, the distance between the mounting hole 31 and any side of the main body 11 is a first distance, and the distance between the limiting hole and any side of the main body 11 is a second distance, the first distance being different from the second distance.

[0049] Since the first distance is different from the second distance, the installation cannot be completed when the installation direction is changed, thereby achieving the anti-fumble effect and reducing the probability of incorrect assembly.

[0050] In an embodiment, the door guide rail 2 is fixed to the frame sheet metal 4, the guide rail end cover 1 is installed between the end of the door guide rail 2 and the frame sheet metal 4, and the third limiting plate 15 is attached to the frame sheet metal 4.

[0051] Through the attachment of the third limiting plate 15 to the frame sheet metal 4, the frame sheet metal 4 is relied on to reduce the shaking of the guide rail end cover 1 in the extension direction of the door guide rail 2.

[0052] In summary, the embodiment of the present application provides a guide rail end cover 1, the embodiment of the present application adopts the mode of cooperation between the mounting buckle 12 and the mounting hole 31, and through the clamping action of the first limiting plate 13, the third limiting plate 15 and the second limiting plate 14, the bolt-free fixation is achieved. In terms of material cost, the cost of the buckle structure is lower than that of the bolt and nut, and the cost of two bolts and two nuts can be saved for each vehicle, thereby significantly reducing the material cost.

[0053] The above is only the preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the technical field, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection range of the present application.
