Description

Technical Field

[0001] The utility model specifically relates to a switching component, a driving assembly and a vehicle. Background Art

[0002] Some vehicles use a frameless door design. Compared with traditional doors, the window glass of a frameless door is subject to less restrictive force in the Y direction (i.e. left-right direction) of the actual vehicle after it drops a certain distance from the top dead center due to the lack of side frames. Based on this, if the passenger closes the door at this time, the window glass and parts related to the window glass will be subjected to force and shake, which is likely to produce abnormal noise (or vibration) that affects the passenger's experience.

[0003] In the related art, the solutions to solve this abnormal noise include increasing the sealing force (or compression load) of related seals such as internal and external water cuts on the vehicle window glass; the disadvantages of such solutions are: first, it will significantly increase the resistance of the vehicle window glass to move up and down, and then significantly increase the operating load of the drive assembly (also known as the glass lifter) used to drive the vehicle window glass up and down; secondly, it will significantly increase the risk of friction abnormal noise between the vehicle window glass and related seals.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle with a frameless door design, and the left front part of the vehicle is provided with a driving assembly for driving the window glass (not shown) to rise and fall, and the driving assembly includes a guide rail 1, an adapter 2, and a slider 3 that can slide along the guide rail 1. In this embodiment, the adapter 2 is connected to the slider 3 and is also slidably connected to the guide rail 1, and as shown in FIG. Figure 3 and Figure 4 As shown, the adapter 2 includes a main body 20 and a bent body 21, the end of the main body 20 and the bent body 21 form a matching groove 22, and the matching groove 22 is used to slide with the guide rail 1; in addition, an elastic support 23 is formed by extending from the groove edge of the matching groove 22 toward the outside of the matching groove 22, one end of the elastic support 23 is a fixed end connected to the matching groove 22 as a whole, and the other end is a free end spaced from the bent body 21 and the main body 20, and the elastic support 23 is used to be between the slider 3 and the guide rail 1, and to abut against the slider 3 and the guide rail 1 at different positions thereof.

[0043] Based on the above arrangement, it can be known that by making the elastic support 23 respectively abut against the slider 3 and the guide rail 1 at different positions thereof, the present embodiment can enhance the matching stability between the slider 3 with the adapter 2 and the guide rail 1 without significantly affecting the sliding smoothness between the slider 3 with the adapter 2 and the guide rail 1, thereby reducing the abnormal noise caused by the occupant closing the door after the window glass leaves the top dead center.

[0044] For a more detailed description, when the adapter 2 abuts against the slider 3 and the guide rail 1 at different positions thereof, when the slider 3 slides, the elastic support 23 can adaptively be in a state of elastic deformation, so as not to overly hinder the sliding of the slider 3; meanwhile, when a passenger closes the door when the window glass leaves the top dead center, the adapter 2 can be supported between the slider 3 and the guide rail 1 through the abutting relationship between itself and the slider 3 and the guide rail 1, thereby reducing the amount of晃动 of the slider 3 relative to the guide rail 1, indirectly increasing the Y-direction limiting force received by the window glass, and ultimately achieving the effect of reducing the abnormal noise when closing the door.

[0045] It can be understood that compared with the solution of increasing the sealing force of the window glass by adding sealing parts such as inner and outer water cutters, the foregoing solution will neither significantly increase the resistance of the window glass to move up and down, nor significantly increase the risk of frictional abnormal noise generated between the window glass and the relevant sealing parts.

[0046] For the above vehicle, the following is a more detailed exemplary setting:

[0047] Please continue to refer to Figure 3 and Figure 4 It should be noted that the adapter 2 of this embodiment is an elastic plastic product. The adapter 2 includes two bending bodies 21, and these two bending bodies 21 extend outward from the upper and lower ends of the main body 20 and respectively form two fitting grooves 22 with the upper and lower ends of the main body 20, so that the adapter 2 can be slidably fitted with the guide rail 1.

[0048] Exemplarily, the middle part of the main body 20 is in a strip shape extending in the up and down direction. The upper end and the lower end of the main body 20 protrude backward relative to the middle part thereof and are in an "L" shape (for the convenience of illustration, Figure 3 the outline I of the dotted line is used to assist in indicating the outline of the main body 20); correspondingly, the bending body 21 is in an "S" shape (for the convenience of illustration, Figure 3 the outline II of the dotted line is used to assist in indicating the bending body 21). The left end of the bending body 21 is integrally connected with the left end of the main body 20, and there is a gap between the right end of the bending body 21 and the right end of the main body 20. The fitting groove 22 formed by connecting the bending body 21 and the main body 20 has a cross-section approximately in the shape of a sock. In this embodiment, the two fitting grooves 22 formed on the adapter 2 communicate with each other in the up and down direction and have an opening structure formed through the foregoing gap at the end far from the bottom of its own groove, so that the guide rail 1 can伸入 the fitting groove 22 as Figure 2 shown and form a connected relationship with the slider 3. It can be understood that the assembly sequence of the slider 3, the adapter 2, and the guide rail 1 can be flexibly determined by those skilled in the art according to needs; in this embodiment, the adapter 2 is first assembled with the slider 3, and then the slider 3 with the adapter 2 is assembled with the guide rail 1.

[0049] Please refer to Figure 2 and Figure 3In order to connect the adapter 2 with the slider 3, in this embodiment, a lug 24 is provided at the upper and lower edges of the right end of each curved body 21, and the lug 24 extends from the curved body 21 toward the rear; the two lugs 24 at the upper and lower ends of the adapter 2 and the curved body 21 between the two lugs 24 form a first notch 25 on the right end of each curved body 21; the first notch 25 is also located at the rear side of each matching groove 22; at the same time, on the front side of the matching groove 22, on the upper and lower ends of the main body 20, a second notch 26 is also provided similar to the first notch 25; the opening directions of the first notch 25 and the second notch 26 are opposite to each other, and the first notch 25 and the second notch 26 are used to be clamped with different parts of the slider 3.

[0050] Corresponding to the configuration of the adapter 2, as Figure 4 and Figure 5 As shown, the slider 3 of this embodiment is provided with a receiving area 31 for matching the adapter 2, a part of the adapter 2 is located in the receiving area 31, and both ends of the receiving area 31 are provided with a groove body 32 with a sock-shaped cross section, the groove body 32 is used to cover the end of the adapter 2, so that a part of the slider 3 and the guide rail 1 placed in the matching groove 22 are located on the opposite side (see Figure 2 ); in addition, a matching portion 33 for engaging with the first notch 25 and the second notch 26 is provided on the accommodating area 31.

[0051] In the present embodiment, when the adapter 2 and the slider 3 need to be assembled, the adapter 2 can be placed in the accommodating area 31 by applying force to the bent body 21 to reduce the opening structure of the matching groove 22, so that the first notch 25 and the second notch 26 are aligned with the matching portion 33 respectively; thereafter, the external force applied to the bent body 21 is removed, and after the bent body 21 is reset due to the elastic force, the first notch 25 and the second notch 26 are snap-fitted in the up and down directions; at the same time, based on the fact that the groove body 32 is a shape imitating the matching groove 22, the adapter 2 placed in the accommodating area 31 is obviously still snap-fitted in the accommodating area 31 in the front-to-back direction and the left-to-right direction. Thereafter, unless force is applied to the bent body 21 again to reduce the opening structure of the matching groove 22 to take out the adapter 2, the adapter 2 will not be detached from the slider 3, and the adapter 2 and the slider 3 will always maintain a firmly connected state, so that as Figure 6 As shown, it cooperates with the guide rail 1.

[0052] Please continue reading Figure 3 and Figure 4 In this embodiment, a boss 27 extends forward from the middle position of the right front edge of the main body 20; Figure 5As shown, after the slider 3 and the adapter 2 are assembled, the boss 27 is the part of the adapter 2 located outside the accommodation area 31 and in contact with the front of the slider 3; the boss 27 is designed to increase the contact area between the adapter 2 and the slider 3, and can also be used as a handle for taking the adapter 2. It can be understood that the boss 27 is not a must-have item. In a possible embodiment without the boss 27, after the slider 3 and the adapter 2 are assembled, the adapter 2 is completely located in the accommodation area 31.

[0053] Please refer back to Figure 2 The guide rail 1 of this embodiment specifically includes a first rail body 11, a second rail body 12 and a side wall 13, wherein the first rail body 11 is the part of the guide rail 1 extending into the matching groove 22 and slidingly matching with the adapter 2, the side wall 13 is formed by extending rightward from the front end of the first rail body 11, and the second rail body 12 is formed by extending forward from the side wall 13. Please refer to Figure 3 and Figure 4 As mentioned above, the adapter 2 includes an elastic support 23, "the elastic support 23 is used to be located between the slider 3 and the guide rail 1, and to abut against the slider 3 and the guide rail 1 at different positions thereof"; a more detailed description of this is that the adapter 2 includes two elastic supports 23; the two elastic supports 23 are uneven strips extending along the length direction of the adapter 2, and the two elastic supports 23 are respectively extended toward each other from the groove edges of the two matching grooves 22; at the same time, one end of each of the two elastic supports 23 is respectively connected to the two matching grooves 22 as a whole to form a fixed end, and the other end of each of the two elastic supports 23 extends to the middle side of the main body 20, and there is a gap between each other, thereby forming a free end of each elastic support 23.

[0054] like Figure 5 As shown, after the adapter 2 and the slider 3 of this embodiment are assembled, the elastic support 23 contacts a surface of the slider 3 in the receiving area 31 between the grooves 32 of the slider 3. Figure 6 As shown in FIG. 1 , after the adapter 2, the slider 3 and the guide rail 1 are assembled, the elastic support 23 is located between the slider 3 and the first rail body 11; Figure 7 and Figure 8 As shown, the elastic support 23 abuts against the guide rail 1 at one of its protrusions (see Figure 8 Indicated by the solid arrow in the middle), in one of the concave parts (see Figure 8 It can be seen that in the process of the slider 3 sliding along the guide rail 1, the elastic support 23 can be supported between the slider 3 and the guide rail 1 without obviously hindering the sliding of the slider 3, thereby increasing the Y-direction limiting force on the window glass and absorbing and buffering the force transmitted to the slider 3 and the guide rail 1 when the window glass is subjected to force due to the door closing action, thereby ensuring that the slider 3 does not shake excessively relative to the guide rail 1.

[0055] Specifically, the elastic support 23 in the present embodiment is provided with only one convex portion and one concave portion. However, it can be understood that, on the premise that the elastic support 23 abuts against the guide rail 1 and the slider 3 at different positions thereof, the shape of the elastic support 23 can be flexibly set by those skilled in the art as needed; for example, in a possible embodiment, a plurality of concave portions and convex portions can be provided on the elastic support 23. In this case, the elastic support 23 abuts against one of the guide rail 1 and the slider 3 at at least one concave portion thereof, and abuts against the other of the guide rail 1 and the slider 3 at at least one convex portion thereof.

[0056] In addition, it can be understood from the above that the intervals between the elastic supports 23 in this embodiment can leave enough deformation space for the elastic deformation of each elastic support 23, and is an important design to ensure that the elastic supports 23 will not obviously hinder the sliding of the slider 3.

[0057] Please refer back to Figure 2 and Figure 3 In order to further reduce the sliding resistance of the slider 3, that is, the friction between the adapter 2 and the guide rail 1, in this embodiment, functional ribs 28 are provided in pairs in the matching groove 22 to ensure that the contact form between the adapter 2 and the guide rail 1 is almost a line contact with less friction.

[0058] Specifically, at the upper portion of the front side wall and the upper portion of the rear side wall of the matching groove 22, as shown in FIG. Figure 3 and Figure 4 As shown, each is provided with a protruding functional rib 28; in the middle of the rear side wall of the matching groove 22 and the rear part of the left side wall, as shown Figure 4 and Fig. 9 As shown, each is provided with a convex functional rib 28; Fig.10 As shown, after the slider 3, the guide rail 1 and the adapter 2 are assembled, the two functional ribs 28 located at the upper part of the front side wall and the upper part of the rear side wall of the matching groove 22 are respectively located at the front and rear sides of the side wall 13, and respectively contact the front and rear side surfaces of the side wall 13; the two functional ribs 28 located at the middle part of the rear side wall and the rear part of the left side wall of the matching groove 22 are respectively located at the left and right sides of the first rail body 11, and respectively contact the left and right side surfaces of the first rail body 11.

[0059] Please refer back to Figure 4 and Figure 5 In order to further reduce the sliding resistance of the slider 3, the present embodiment further provides a protruding contact rib 29 on the front surface of the main body 20, which is similar to the design of the aforementioned functional rib 28. When the slider 3 and the adapter 2 are assembled, the contact rib 29 is the part where the front surface of the main body 20 contacts the accommodating area 31. The contact rib 29 can make the front surface of the main body 20 contact the accommodating area 31 in a nearly linear contact manner, thereby indirectly reducing the sliding resistance of the slider 3.

[0060] Please continue reading Fig.11 As the slider 3 slides along the guide rail 1, it will inevitably exert force on the guide rail 1. Therefore, in order to ensure that the guide rail 1 will not be easily deformed due to this force, thereby affecting the stability of the slider 3, the first rail body 11, the side wall 13 and the second rail body 12 are idealized as dotted lines along their extension directions. In this embodiment, the angle α formed by the second rail body 12 and the side wall 13, and the angle β formed by the first rail body 11 and the side wall 13 are both 90°. It can be understood that such a configuration can enable the first rail body 11, the side wall 13 and the second rail body 12 to form a structure with considerable strength, thereby ensuring that the guide rail 1 will not be easily deformed.

[0061] In summary, by designing an adapter 2 with an elastic support 23, the utility model can reduce the shaking amount of the slider 3 relative to the guide rail 1 when the force is applied, without significantly increasing the up and down resistance of the window glass and the risk of friction noise generated by the window glass and related seals, thereby indirectly increasing the Y-direction restriction force on the window glass, increasing the stability of the window glass at the moment of closing the frameless door, and reducing the abnormal noise caused by the occupant closing the door after the window glass leaves the top dead center.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
