Description

Technical Field

[0001] The present invention relates to the technical field of sunshades, and particularly to a wheeled slider for a vehicle sunshade, a sunshade and an automobile. Background Art

[0002] At present, the structure of the slide rail for the sunshade of a passenger car and the slider matched therewith adopts an ordinary square slider, and a brush-like structure is added to its surface to match a square groove-type slide rail to realize the up and down sliding of the sunshade; the following problems exist in this solution: First, since only the brush is relied on for limiting between the sunshade slide rail and the slider, there are phenomena of abnormal noise and vibration due to insufficient unilateral force of the brush during the driving of the vehicle, especially when the vehicle passes through a bumpy road surface, the vibration and abnormal noise are particularly obvious, affecting the NVH performance of the whole vehicle and the riding comfort; Second, due to the addition of the brush, the slider makes the sunshade uneven during the up and down sliding process, affecting the user operation experience. Summary of the Invention

[0003] To solve the above problems, the present invention proposes a wheeled slider for a vehicle sunshade and an automobile, which solves the problems of vibration and abnormal noise of the sunshade during the driving of the vehicle and the unevenness of the sunshade during the up and down sliding process through the perfect cooperation of rollers and elastic elements; on the premise of keeping the structure of the original sunshade slide rail unchanged, the problems of the vehicle are solved by only changing the structure of the sunshade slider; on the premise of keeping the development cycle of the whole vehicle unchanged, the efficiency is improved and the development cost is saved.

[0004] The present invention proposes a wheeled slider for a vehicle sunshade, including a buckle cover, a slider body, six rollers, three roller shafts and roller shaft elastic support elements;

[0005] The buckle cover is buckled and fixed with the slider body, and a horizontally hollow accommodating cavity is formed between the buckle cover and the slider body, and the two form a rotation limiting cavity for the roller shaft and the roller;

[0006] Rotating shaft holes distributed symmetrically in an isosceles triangle are respectively opened on the corresponding inner side walls of the buckle cover and the slider body. The rotating shaft hole near the rear end or the rotating shaft hole near the front end is an oblong hole. This design enables a part of the rollers on the two roller shafts at the front end to be exposed outside the front end face of the accommodating cavity, and a part of the rollers on one roller shaft at the rear end to be exposed outside the rear end face of the accommodating cavity. The rollers exposed at the front and rear ends can respectively elastically slide and contact with the front and rear end walls of one side of the sunshade slide rail, avoiding the vibration and abnormal noise of the slider in the slide rail in the prior art. Both ends of the three roller shafts are respectively rotatably accommodated in the corresponding rotating shaft holes provided on the buckle cover and the slider body;

[0007] The roller elastic support elements are respectively in rolling contact with the three rollers in a limited way, so as to respectively enable the rollers on the two front rollers and the roller on the rear roller to be elastically in contact with the front and rear end walls of the sunshade rail on one side. When the position of the sunshade does not need to be adjusted, the rollers of the wheeled slider of the vehicle sunshade are in close contact with the front and rear end walls of the sunshade rail through the elastic force of the roller elastic support element. When the position of the sunshade needs to be changed, manually pull up or down the sunshade fixedly connected to the wheeled slider of the vehicle sunshade. When the pulling force is greater than the frictional force, the sunshade will move up or down. The two rollers are respectively sleeved on the rotating shafts on both sides of a roller. The corresponding inner side walls of the buckle cover and the slider body axially limit the rollers sleeved on both sides of the same roller;

[0008] The rollers on the three rollers are partially exposed outside the front end face or the rear end face of the accommodating cavity formed by the buckle cover and the slider body buckled together, so that the rollers can be elastically in contact with the front and rear end walls of the sunshade rail, avoiding the abnormal noise generated by the collision between the slider and the rail in the prior art, and at the same time realizing that the slider structure can stay arbitrarily between the front and rear end walls of the sunshade rail.

[0009] The roller elastic support element is integrally bent from an elastic metal strip. The selection of the material should ensure both the elastic force and the recoverability of the roller elastic support element. The roller elastic support element is integrally in an M shape. Two lower ends of the M-shaped roller elastic support element are respectively provided with a concave semi-circular arc edge, and the upper end of the M-shaped roller elastic support element is provided with a semi-circular arc edge opposite to the two concave semi-circular arc edges. The opposite semi-circular arc edge is in sliding contact with the front circumferential groove of the roller close to the rear end, and the two concave semi-circular arc edges are respectively in contact with the rear circumferential groove of the roller close to the front end. The roller elastic support element applies elastic forces forward and backward respectively, so that the rollers on the two front rollers and the roller on the rear roller are respectively in elastic pressure contact with the front and rear end walls of the sunshade rail, increasing the frictional force between the two and ensuring that the sunshade will not move up and down arbitrarily.

[0010] In the middle of the front end face of the buckle cover, a front limit dust-proof baffle protrudes corresponding to the position of the roller close to the rear end. On both sides of the rear end face of the buckle cover, rear limit dust-proof baffles protrude corresponding to the positions of the two rollers close to the front end. Its function is to prevent foreign objects from entering the inside of the accommodating cavity formed by the buckle cover and the slider body, resulting in the rollers being stuck and unable to rotate, and also prevent the elastic fatigue of the roller elastic support element. The baffle positions are exposed outside the accommodating cavity, scratching the front and rear end walls of the sunshade rail.

[0011] Mortise and tenon structure connectors are respectively arranged at the corresponding positions of the upper and lower ends of the inner surfaces of the buckle cover and the slider body. The buckle cover and the slider body are fixedly connected to each other through the mortise and tenon structure connectors.

[0012] At the positions of the upper and lower tenon and mortise structure connectors corresponding to the outer end face of the cover, self-tapping screws are screwed in to further strengthen the connection firmness between the cover and the slider body.

[0013] In the middle of the outer end face of the slider body, a first limit boss of the lower pull bar and a second limit boss of the lower pull bar protrude respectively. And at the upper and lower ends of the outer end face of the slider body, a first limit groove of the lower pull bar and a second limit groove of the lower pull bar are respectively provided. The end face of the first limit boss of the lower pull bar is recessed downward with a third limit groove of the lower pull bar, so that the left and right ends of the lower pull bar with a matching structure can be respectively inserted and fixed on a wheeled slider of a vehicle sunshade.

[0014] On the outer end face of the cover, a shock-absorbing and anti-wearing pad with a matching shape is clamped and fixed by two self-tapping screws. The shock-absorbing and anti-wearing pad is adhesively fixed between the outer end face of the cover. Its function is that the shock-absorbing and anti-wearing pad is in interference fit with the inner wall of the side end face of the sunshade slide rail, so that the wheeled slider of the vehicle sunshade and the lower pull bar are always inserted and fixed. This structure not only ensures that the wheeled slider of the vehicle sunshade can roll smoothly in the slide way, but also eliminates the abnormal noise caused by vibration, improves the operation experience of the members and the NVH performance of the whole vehicle, thereby improving the riding experience of the whole vehicle.

[0015] The material of the roller is non-metallic plastic or elastic rubber to further increase the friction force and reduce the possibility of abnormal noise generated between the wheeled slider of the vehicle sunshade and the sunshade slide rail.

[0016] The present invention also provides a sunshade, which includes a wheeled slider of a vehicle sunshade, and also includes two left and right sunshade slide ways, a sunshade scroll, a window sill guard plate, and a sunshade lower pull bar; the lower ends of the two left and right sunshade slide ways are respectively fixedly connected to the left and right ends of the window sill guard plate. The upper left and right sides of the sunshade scroll are respectively pivotally connected to the two left and right sunshade slide ways. The sunshade of the sunshade scroll is fixedly connected to the sunshade lower pull bar. The left and right ends of the sunshade lower pull bar are respectively inserted and matched with the two left and right wheeled sliders of the vehicle sunshade. Each sunshade slide way is a groove body structure with an opening at the inner side end. The rollers on the three rollers of each wheeled slider of the vehicle sunshade are respectively in sliding contact with the inner walls of the front and rear end faces of the corresponding sunshade slide way, and the shock-absorbing and anti-wearing pad of the wheeled slider of the vehicle sunshade is in interference fit with the inner surface of the side wall of the corresponding sunshade slide way, so that the wheeled slider of the vehicle sunshade and the sunshade lower pull bar are always in contact. It is necessary to ensure the smoothness of the up and down sliding of the sunshade and eliminate the abnormal noise generated by vibration when the vehicle is on a bad road. The two ends of the sunshade lower pull bar and the two wheeled sliders of the vehicle sunshade inserted and fixed can slide up and down in the two left and right sunshade slide ways.

[0017] The present invention also provides an automobile, which includes a sunshade and also includes a vehicle body. The upper and lower ends of the two left and right sunshade slide ways of the sunshade are respectively screwed and fixed to the circumferential sheet metal decorative surfaces of the vehicle body corresponding to the windows.

[0018] Beneficial effects

[0019] Through the perfect cooperation between the roller and the elastic element, the present invention solves the problems of vibration and abnormal noise of the traditional vehicle sunshade during vehicle driving, and the problem of unevenness during the up and down sliding of the sunshade; on the premise of keeping the original sunshade slide rail structure unchanged, by only changing the structure of the sunshade slider, the problems existing in the vehicle are solved; on the premise of keeping the overall vehicle development cycle unchanged, the efficiency is improved and the development cost is saved.
