Guide structure, skylight assembly and vehicle

Abstract

The utility model relates to a guide structure, a skylight assembly and a vehicle. The guide structure comprises a guide rail and a sliding block. The guide rail extends in the first direction and comprises a wall body and a sliding cavity defined by the wall body. The sliding block is arranged in the sliding cavity and comprises a main body part, a first deformation part and a second deformation part which are connected. The first deformation part abuts against the wall body and can generate extrusion deformation in the second direction. The second deformation part abuts against the wall body and can generate extrusion deformation in the third direction. The first direction, the second direction and the third direction are perpendicular to one another. According to the guiding structure, the sliding block abuts against the wall body, so that when the sliding block moves in the first direction, no gap exists between the sliding block and the wall body in the second direction and the third direction, and abnormal sound is avoided. Due to the fact that the first deformation part and the second deformation part can both deform, contact between the sliding block and the wall body is non-rigid contact, and frictional resistance between the sliding block and the wall body is controlled.

[0002] With the improvement of people's requirements for vehicle appearance and the advancement of technology, more and more panoramic sunroofs installed externally are being used in vehicles. The glass guide structure of the panoramic sunroof can slide open and close. The assembly accuracy of the guide structure also affects the operation of the panoramic sunroof, and thus affects the experience of vehicle users.

[0003] Specifically, if the gap between the slider and the guide rail of the guide structure is too small, the resistance will increase, which will lead to increased motor load, increased noise, increased wear and increased deformation. In order to reduce the resistance, if the matching gap between the slider and the guide rail is increased, it will cause shaking and abnormal noise. Utility Model Content

DETAILED DESCRIPTION

[0024] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0025] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0026] refer to Figures 1 to 3, the present application provides a guide structure 100. The guide structure 100 includes a guide rail 1 and a slider 2. The guide rail 1 extends along a first direction X, and includes a wall body 11 and a sliding cavity 12 surrounded by the wall body 11. The slider 2 is arranged in the sliding cavity 12, and includes a connected main body 21, a first deformation portion 22 and a second deformation portion 23. The first deformation portion 22 abuts against the wall body 11, and can produce an extrusion deformation in a second direction Y. The second deformation portion 23 abuts against the wall body 11, and can produce an extrusion deformation in a third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0027] The guide rail 1 extends along the first direction X, so the slider 2 can move in the first direction X. Figure 1 In the perspective shown, the second direction Y is along the up-down direction, and the third direction Z is along the left-right direction. Therefore, the first deformable portion 22 allows the slider 2 to adjust its up-down position in the sliding cavity 12, while the second deformable portion 23 allows the slider 2 to adjust its left-right position in the sliding cavity 12.

[0028] By such a configuration, the slider 2 is in contact with the wall 11, so when the slider 2 moves along the first direction X, there is no gap between the slider 2 and the wall 11 in the second direction Y and the third direction Z, thus avoiding abnormal noise. Since both the first deformation portion 22 and the second deformation portion 23 can be deformed, the contact between the slider 2 and the wall 11 is a non-rigid contact, and the friction resistance between the two is controlled. It can be seen that the guide structure 100 of the present application overcomes the contradiction between "increasing the gap to reduce resistance" and "reducing the gap to eliminate abnormal noise", and the resistance is effectively controlled while reducing the abnormal noise.

[0029] It should be noted that the first deformable portion 22 can be deformed in the second direction Y, which should be understood as at least deforming in the second direction Y, that is, as long as the force on the first deformable portion 22 can be decomposed into at least the force in the second direction Y to deform the first deformable portion 22, it should be understood as deformation in the second direction Y. Similarly, the second direction Y can be deformed in the third direction Z, which should also be understood as at least deforming in the third direction Z. This application will not elaborate on this.

[0030] The wall body 11 includes a first side wall 111 and a second side wall 112 arranged in the third direction Z. The first side wall 111 and the second side wall 112 are arranged opposite to each other. Figure 1As shown, in some embodiments, the first side wall 111 is provided with a limiting groove 1111 communicating with the sliding cavity 12. The limiting groove 1111 extends along the first direction X. The first deformable portion 22 abuts against the groove wall of the limiting groove 1111 in the second direction Y. In this way, the limiting groove 1111 can limit the position of the slider 2 in the second direction Y to prevent the slider 2 from being separated from the guide rail 1. When the assembler assembles the guide structure 100, it is only necessary to place the slider 2 into the sliding cavity 12 along the first direction X and set the first deformable portion 22 in the limiting groove 1111.

[0031] The limiting groove 1111 may be formed by machining a concave groove structure on the first side wall 111. Alternatively, Figure 1 As shown, two protrusions are formed on the first side wall 111, thereby forming a limiting groove 1111 between the two protrusions. This arrangement is conducive to improving the thickness uniformity of the wall body 11, avoiding stress concentration or excessive weakness of a certain structure due to a small wall thickness.

[0032] Combination Figure 2 and Figure 3 In some embodiments, the main body 21 includes a protrusion 211 on one side facing the first side wall 111. The protrusion 211 is disposed in the limiting groove 1111. The first deformable portion 22 includes an annular elastic body. The elastic body is sleeved on the protrusion 211 and has a gap with the protrusion 211 in the second direction Y. The gap allows the elastic body to deform in the second direction Y, thereby allowing the slider 2 to adjust its position in the second direction Y. At the same time, the elasticity of the elastic body allows the first deformable portion 22 to always maintain contact with the limiting groove 1111, thereby preventing the slider 2 from shaking in the second direction Y and causing abnormal noise.

[0033] like Figure 3 As shown, the protrusion 211 can be set to a cylindrical shape, while the elastic member 221 is set to an elliptical ring shape. The major axis of the elliptical ring-shaped elastic member 221 extends along the second direction Y, so there is a gap between the elastic member 221 and the protrusion 211 in the second direction Y. Alternatively, the protrusion 211 can be set to an elliptical cylinder with a major axis extending along the first direction X, while the elastic member 221 is set to a circular ring shape. This setting method can also make a gap between the elastic member 221 and the protrusion 211 in the second direction Y. However, the present application does not limit the specific shapes of the protrusion 211 and the elastic member 221.

[0034] In order to reduce the friction between the first deformation portion 22 and the guide rail 1, as Figure 1As mentioned above, in some embodiments, the first deformation part 22 further includes a wear-resistant part 222. The wear-resistant part 222 is sleeved on the side of the elastic body facing the limiting groove 1111. The wear-resistant part 222 is arranged between the elastic body and the wall surface of the limiting groove 1111, so as to reduce the sliding friction between the first deformation part 22 and the limiting groove 1111 when the slider 2 slides. In addition, after the guide structure 100 is used for a long time, the maintenance personnel can maintain the normal operation of the slider 2 by replacing the wear-resistant part 222 without replacing the slider 2 or the elastic part 221 as a whole.

[0035] exist Figure 1 In the illustrated embodiment, the wear-resistant part 222 is sleeved on the side of the elastic body in the second direction Y and one side in the third direction Z, so the friction resistance generated by the first deformable part 22 contacting the wall 11 in the second direction Y and the third direction Z can be controlled by the wear-resistant part 222. In other embodiments, the wear-resistant part 222 can also be only provided on one side of the elastic body away from the protrusion 211. The present application is not limited to this.

[0036] Combination Figure 1 and Figure 2 In some embodiments, the side of the main body 21 facing the second side wall 112 includes a first weight-reducing groove 212. The projection of the protrusion 211 in the second direction Y is located in the first weight-reducing groove 212. The provision of the first weight-reducing groove 212 can reduce the weight of the slider 2. Take the second direction Y as the gravity direction as an example. If the weight of the slider 2 increases, the friction between the first deformation portion 22 and the wall body 11 increases, which is not conducive to reducing the resistance between the slider 2 and the guide rail 1. It can be seen that the provision of the first weight-reducing groove 212 is conducive to reducing the resistance between the slider 2 and the guide rail 1. In addition, since the slider 2 is provided with the protrusion 211, the thickness of the slider 2 corresponding to the position of the protrusion 211 increases, and there may be a risk of stress concentration. The projection of the protrusion 211 in the second direction Y is located in the first weight-reducing groove 212, and the slider 2 is as Figure 1 As shown, there is a first weight-reducing groove 212 behind the position where the protrusion 211 is provided. This arrangement can effectively reduce the wall thickness of the slider 2 at the position of the protrusion 211 and improve the uniformity of the wall thickness of the slider 2 as much as possible.

[0037] In some embodiments, the second deformable portion 23 is disposed on the side of the main body 21 facing the second side wall 112 and is configured as a flexible body. The deformability of the flexible body allows the main body 21 to be assembled in the sliding cavity 12. If its position in the third direction Z is to be adjusted, this can be achieved by squeezing the flexible second deformable portion 23. The configuration of the flexible body is simple and effective, which is conducive to cost control.

[0038] The second deformable portion 23 of this embodiment can be connected to the surface of the main body 21 facing the second side wall 112 by means of bonding, clamping, etc. Figure 2 In some embodiments, a receiving groove is provided on one side of the main body 21 facing the second side wall 112. And the second deformation portion 23 is provided in the receiving groove. It is easy to understand that the slider 2 slides along the first direction X, so the friction between the second deformation portion 23 and the second side wall 112 is along the first direction X. If the second deformation portion 23 is directly provided on the planar second side wall 112, it is easy to fall off due to the friction. Therefore, this embodiment provides a receiving groove and arranges the second deformation portion 23 in the receiving groove, so that the side wall surface of the receiving groove can abut against the second deformation portion 23, thereby supporting the second deformation portion 23 in the first direction X, thereby improving the structural connection stability between the second deformation portion 23 and the main body 21.

[0039] In some embodiments, the second deformable portion 23 is provided with a deformation groove on the side facing the main body 21. After the flexible body is extruded and deformed, it can bend toward the deformation groove. This arrangement reduces the thickness of the second deformable portion 23, increases the flexibility of the second deformable portion 23, and is conducive to reducing the friction between the second deformable portion 23 and the second side wall 112. In the embodiment where the main body 21 is provided with a receiving groove, the second deformable portion 23 is difficult to deform in the direction of the receiving groove, so the deformation groove provides a deformation space for the flexible body, reducing the pressure of the second deformable portion 23 on the wall 11.

[0040] Further, in an optional embodiment, the main body 21 includes a second weight-reducing groove 213 on one side facing the first side wall 111. The projection of the second deformation portion 23 in the second direction Y is located in the second weight-reducing groove 213. Similar to the first weight-reducing groove 212, the provision of the second weight-reducing groove 213 can reduce the weight of the slider 2, thereby reducing the problem of increased friction due to increased gravity. At the same time, the projection of the second deformation portion 23 in the second direction Y is in the second weight-reducing groove 213, which is conducive to improving the uniformity of the wall thickness of the slider 2 and avoiding stress concentration.

[0041] like Figure 2 As shown, the slider 2 of the present application can be provided with a first deformation portion 22 and two second deformation portions 23. Moreover, the first deformation portion 22 is provided in the middle of the slider 2 in the first direction X, and the second deformation portions 23 are respectively located on both sides of the first deformation portion 22 in the first direction X. The staggered first deformation portions 22 and second deformation portions 23 facilitate the slider 2 to be provided with the first weight-reducing groove 212 and the second weight-reducing groove 213. In addition, the two second deformation portions 23 can prevent the slider 2 from being subjected to a torque generated by a force in the third direction Z, which causes the slider 2 to be twisted and offset in position.

[0042] also, Figure 1In the illustrated embodiment, the first deformable portion 22 is an elastic member 221, and the elastic member 221 is sleeved with the protrusion 211. Therefore, the elastic deformation direction of the elastic member 221 is the second direction Y. The third direction Z is the rigid direction of the elastic member 221, which is difficult to deform. Therefore, when the first deformable portion 22 abuts against the limiting groove 1111, the deformation in the third direction Z is only regulated by the second deformable portion 23. Compared with the embodiment in which the slider 2 has deformable portions on both sides in the third direction Z to press and generate the force applied to the first side wall 111 and the second side wall 112 in the third direction Z, this arrangement can reduce the pressure generated by the second deformable portion 23 on the wall body 11, thereby reducing the friction between the slider 2 and the guide rail 1.

[0043] In the above embodiments, the materials of the wear-resistant member 222 and the flexible second deformation portion 23 can be polyoxymethylene, polyamide, polytetrafluoroethylene or a mixture thereof. In order to increase the strength of the second deformation portion 23 of the wear-resistant member 222, in some embodiments, the outer layer material of the wear-resistant member 222 and the second deformation portion 23 is polyoxymethylene, polyamide or polytetrafluoroethylene, and the inner layer is thicker and is thermoplastic elastomer or rubber.

[0044] In an optional embodiment, the first deformable portion 22 may also be disposed on the side of the slider 2 facing the bottom wall 113 of the wall body 11. The first deformable portion 22 may be configured as a deformable flexible body. The deformable flexible body can change the position of the first deformable portion 22 in the second direction Y.

[0045] In order to reduce the friction between the slider 2 and the guide rail 1, in some embodiments, a lubricant may be provided between the first deformable portion 22 and the wall 11, and between the second deformable portion 23 and the wall 11. The provision of the lubricant can eliminate abnormal noises by achieving zero contact between the slider 2 and the guide rail 1, while reducing the friction caused by zero contact.

[0046] Based on the above embodiments, the present application further provides a sunroof assembly (not shown). The sunroof assembly includes a driving member (not shown), a glass (not shown) and the guide structure 100 described in the above embodiments. The driving member is connected to the slider 2 to drive the slider 2 to move in the sliding cavity 12 along the first direction X. The glass is connected to the slider 2. The driving member can be arranged as follows: Figure 1 In the driving cavity 13 shown, the glass is driven to open and close along the first direction X by driving the slider 2 to move.

[0047] The sunroof assembly is provided with the guide structure 100 of the present application, which has low friction resistance and makes the opening and closing of the glass smoother. At the same time, the first deformable portion 22 and the second deformable portion 23 can eliminate the gap between the slider 2 and the guide rail 1, avoiding the collision between the slider 2 and the guide rail 1 during the opening and closing of the glass, thereby making it quieter.

[0048] The present application also provides a vehicle (not shown), comprising the sunroof assembly described in the above embodiment. Since the sliding friction of the guide structure 100 can be controlled, the motor load of the vehicle can be controlled. In addition, the arrangement of the first deformable portion 22 and the second deformable portion 23 can eliminate the gap between the slider 2 and the guide rail 1, which can not only avoid abnormal noise when the glass is opened and closed, but also avoid noise during the bumpy driving of the vehicle.

[0049] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
