[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] like Figures 1 to 3 As shown, the utility model is a mounting structure assembly for an automobile guide rail 1 and a seal 2, comprising: a guide rail 1, which has a first main body 10 and a second main body 11 arranged at a height difference, a connecting plate 12 is arranged between the first main body 10 and the second main body 11, and a step 120 is formed on the connecting plate 12; a seal 2 and an elastic strip 3, the seal 2 has a first sealing block 20 and a second sealing block 21 arranged at a height difference, the first sealing block 20 is movably pressed against the first main body 10, and the second sealing block 21 is movably pressed against the second main body 11; the elastic strips 3 are respectively movably pressed against the first main body 10 and the inner wall of the second main body 11, and a first engaging groove 200 is formed together with the first sealing block 20 on one side of the elastic strip 3, and a second engaging groove 210 is formed together with the second sealing block 21 on the other side of the elastic strip 3; when the elastic strip 3 moves along the length direction of the guide rail 1, the first engaging groove 200 can be movably inserted into the connecting plate 12 and pressed against the bottom wall of the step 120 when the first sealing block 20 is aligned and movably pressed against the first main body 10; the second engaging groove 210 can be movably inserted into the connecting plate 12 and pressed against the top wall of the step 120 when the second sealing block 21 is aligned and movably pressed against the second main body 11.

[0030] Compared with the traditional method of installing the seal 2 by beveling the end of the guide rail 1, this embodiment forms a step 120 on the connecting plate 12. The step 120 can ensure the close fit between the guide rail 1 and the seal 2. Specifically, Figures 1 to 3As shown, during the installation process, the workers can pre-align the first sealing block 20 and the second sealing block 21 on the sealing member 2 with the first main body part 10 and the second main body part 11 on the guide rail 1. Since the elastic strip 3 is connected to the bottom wall of the sealing member 2 in this embodiment, as the elastic strip 3 is placed in the guide rail 1, the elastic strip 3 can move along the length direction of the guide rail 1 during the process of sealing the end of the guide rail 1, thereby effectively guiding the first clamping groove 200 and the second clamping groove 210 to align with the step 120 on the connecting plate 12. As the elastic strip 3 continues to move, the first clamping groove 200 can be aligned and movably inserted and tightly abut against the bottom wall of the step 120, so as to tightly attach the first sealing block 20 to the first main body part 10. Similarly, the second clamping groove 210 is synchronously aligned and movably inserted and tightly abut against the top wall of the step 120, so as to tightly attach the second sealing block 21 to the second main body part 11. The design of the step 120 effectively solves the sealing requirement of the two sealing blocks with height difference on the whole end of the guide rail 1. Once the sealing member 2 and the elastic strip 3 are fixed, they will maintain the state of tightly attaching to the guide rail 1, thereby providing effective sealing effect. As can be seen, through the design of the movable and tight attachment of the sealing member 2 to the main body part of the guide rail 1, and the additional pressure provided by the elastic strip 3, it can be ensured that even if vibration or temperature change is encountered during the driving of the vehicle, good sealing performance can be maintained. In addition, the structure allows quick installation and disassembly, does not require additional tools, reduces installation time and cost, meets the installation structure and sealing requirement of the guide rail 1 and the sealing member 2, prolongs the service life, and also guarantees the performance of the whole vehicle and the user experience.

[0031] Preferably, the step 120 in this embodiment includes a first step 120a and a second step 120b (both composed of a horizontal surface and a vertical surface connected to each other) connected to each other. Because of the existence of the first step 120a and the second step 120b, the first clamping groove 200 and the second clamping groove 210 can find their positions more accurately, i.e., the first clamping groove 200 tightly abuts against the bottom wall of the first step 120a, and the second clamping groove 210 tightly abuts against the top wall of the second step 120b, so that the first sealing block 20 and the second sealing block 21 on the sealing member 2 can be effectively fixed, the stability of the whole structure is enhanced, the tight attachment between the sealing member 2 and the guide rail 1 is guaranteed, external impurities are effectively prevented from entering and internal substances are effectively prevented from leaking, and the sealing performance is improved.

[0032] The elastic strip 3 has a first anti-disengagement part 30 and a second anti-disengagement part 31. The first anti-disengagement part 30 is connected to the first sealing block 20, and the second anti-disengagement part 31 is connected to the second sealing block 21. A tensioning block 32 is connected between the bottom ends of the first anti-disengagement part 30 and the second anti-disengagement part 31, and the first anti-disengagement part 30 and the second anti-disengagement part 31 can be extruded or expanded towards each other.

[0033] As Figure 2 and Figure 3 shown, in the process of placing the elastic strip 3 into the guide rail 1, due to the extrusion of both sides of the guide rail 1, the first anti-drop part 30 and the second anti-drop part 22 can be extruded towards each other and allowed to extend into the guide rail 1 by the tensioning effect of the tensioning block 32. It is worth noting that at this time, the first anti-drop part 30 and the second anti-drop part 31 are under the expansion force of the tensioning block 32, so that a certain extrusion force is applied to the inner wall of both sides of the guide rail 1 (i.e. the main body part), which not only accurately guides the two sealing blocks to align with the corresponding main body part, but also effectively prevents the sealing element 2 from accidentally falling out of the guide rail 1 during use, thereby improving the stability and reliability of the entire system. Moreover, due to the effect of the tensioning block 32, even if the vehicle encounters vibration or other external forces during driving, the first anti-drop part 30 and the second anti-drop part 31 can still effectively constrain the sealing blocks, ensuring that the sealing element 2 will not easily fall off. If it is necessary to disassemble or replace the sealing element 2, only appropriate force needs to be applied to separate the first anti-drop part 30 and the second anti-drop part 31, and then the elastic strip 3 and the sealing element 2 can be easily removed, which is simple in overall operation and provides convenience for subsequent replacement and maintenance operations.

[0034] The tensioning block 32 is formed with an arc-shaped protruding block 320 along the length direction of the guide rail 1, which allows the first anti-drop part 30 and the second anti-drop part 31 to be extruded or expanded towards each other.

[0035] Further, as Figure 2 and Figure 3 shown, the design of the arc-shaped protruding block 320 allows the first anti-drop part 30 and the second anti-drop part 31 to automatically adjust the distance between the two anti-drop parts during movement, so as to achieve smooth and precise positioning. In addition, the arc-shaped protruding block 320 can also guide the anti-drop parts to be precisely extruded or expanded towards each other, ensuring that the first clamping groove 200 and the second clamping groove 210 can be accurately embedded into the corresponding step 120, reducing installation errors. Finally, the additional constraint force provided by the arc-shaped protruding block 320 enhances the stability of the entire structure, which can maintain the stable position of the sealing element 2 even under dynamic conditions (such as vibration during vehicle driving), greatly optimizing the assembly process and improving the structural stability, reducing the risk of failure caused by external factors, thereby prolonging the service life of the component.

[0036] Preferably, as Figure 2 and Figure 3As shown, the first anti-falling part 30 is further provided with an extension block 300 on the side wall close to the bottom end, and an arc-shaped protruding block 320 is connected to the extension block 300 away from the end of the second anti-falling part 31, so that the first anti-falling part 30 and the second anti-falling part 31 are arranged in a non-coplanar manner. As a result, the stability of the sealing element 2 is maintained, the risk of falling is reduced, the machining precision of the flatness of the side wall of the connecting plate 12 is reduced, the smoothness of the installation of the anti-falling part is avoided due to the unevenness of the side wall, and the stability of the sealing block and the main body part when the sealing block and the main body part are tightly attached to achieve the required sealing effect is ensured.

[0037] Further preferably, the first main body part 10 and the second main body part 11 are each provided with a circular arc transition surface 121 at the connection with the connecting part, which reduces the frictional resistance of the first clamping groove 200 and the second clamping groove 210 when inserted into the corresponding step 120, making the entire installation process smoother and faster. Through smooth transition, stress concentration problems caused by sharp corners or sharp edges are avoided, the risk of damage to the assembly during use is reduced, and the service life is prolonged. In addition, the circular arc transition surface 121 helps the sealing element 2 to tightly fit with the guide rail 1, providing better sealing effect, especially under dynamic conditions (such as vibration during vehicle driving).

[0038] The sealing element 2 further comprises an anti-falling block 22 arranged along the length direction of the elastic strip 3, and the first anti-falling part 30 and the second anti-falling part 31 are respectively provided with the first clamping groove 200 and the second clamping groove 210 formed with the anti-falling block 22, and the inner wall of the anti-falling block 22 is formed with a locking arc surface 220, which is tightly attached to the circular arc transition surface 121.

[0039] Further preferably, as shown in Figure 2 and Figure 3 As the first clamping groove 200 is inserted into the bottom wall of the first step 120a, and the second clamping groove 210 is inserted into the top wall of the second step 120b, the locking arc surface 220 of the anti-falling block 22 also begins to tightly fit the circular arc transition surface 121 on the guide rail 1. Once the sealing element 2 is fixed, the tight fit between the locking arc surface 220 and the circular arc transition surface 121 can provide additional restraint force to prevent the sealing element 2 from loosening due to vibration or other external forces during vehicle driving.

[0040] The first main body part 10 is provided with a first hem 100, and the second main body part 11 is provided with a second hem 110, both of which are provided with a guide groove 122 with the connecting plate 12, and the first anti-falling part 30 or the second anti-falling part 31 is movably clamped in the guide groove 122.

[0041] Further preferably, as shown in Figure 2 and Figure 3As shown, in the process of embedding the first engaging groove 200 into the bottom wall of the first step 120a and embedding the second engaging groove 210 into the top wall of the second step 120b, the first hem 100 and the second hem 110 provide a precise path for the first anti-disengagement part 30 or the second anti-disengagement part 31 from the guide groove 122 formed by the connecting plate 12, ensuring that they can accurately reach the predetermined position, which effectively reduces the error during installation, simplifies the installation steps, reduces the operation difficulty, and ensures that the assembly quality can meet the required use requirements.

[0042] Further preferably, as Figure 2 Figure 3 Figures 1 to 3 As shown, the first sealing block 20 and the second sealing block 21 in the embodiment are both formed with a cladding surface 230 in the length direction of the guide rail 1, and the cladding surface 230 is designed in a convex manner relative to the sealing block. Therefore, in the process of tightly attaching the sealing block to the main body part, the cladding surface 230 can be tightly attached to the outer wall of the guide rail 1 to guide the tight attachment of the sealing block and the end of the main body part. Moreover, the design of the cladding surface 230 significantly improves the contact area between the sealing member 2 and the guide rail 1, providing better sealing effect, especially covering the surface of the guide rail 1 in the horizontal direction, effectively preventing foreign matter from entering and internal substances from leaking.

[0043] Further preferably, the embodiment further forms a connecting block 201 on the first sealing block 20 and a connecting groove 211 on the second sealing block 21. Without affecting the required sealing effect of the sealing member 2 on the guide rail 1, the design of the connecting block 201 and the connecting groove 211 significantly improves the functionality of the system, so that the sealing member 2 can not only provide a sealing function, but also reliably assemble with other external parts, expand the application scenarios, and increase the adaptability and flexibility of the overall structure.
