DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be further described in detail in combination with the drawings and specific embodiments.

[0029] Referring to Figures 1-6As shown in the drawings, the anti-jamming sunroof guide rail assembly comprises a guide rail device 1, a sliding seat 4 arranged in the guide rail device 1, and a fixed seat 2 fixed to the top of the guide rail device 1 for preventing sundries from entering the inside thereof. The top of the guide rail device 1 is provided with a guide sliding groove 13 for mounting the sliding seat 4.

[0030] The inside of both sides of the guide rail device 1 is provided with an oil storage chamber 3 for storing lubricating oil.

[0031] The side wall of the guide sliding groove 13 is provided with a limiting guide plate 14. The bottom of the limiting guide plate 14 is provided with a second mounting groove 15. A plurality of oil guiding grooves 31 in communication with the oil storage chamber 3 are equidistantly arranged in the second mounting groove 15 along the central axis of the guide sliding groove 13.

[0032] The second mounting groove 15 is fixedly provided with a sponge 6 for applying lubricating oil to the sliding block.

[0033] By arranging the oil storage chamber 3 in the inside of both sides of the guide rail device 1 and the oil guiding groove 31 in the inside of the second mounting groove 15, the oil guiding groove 31 can guide the lubricating oil stored in the oil storage chamber 3 to the inside of the second mounting groove 15. At this time, the sponge 6 in the second mounting groove 15 can absorb the lubricating oil, so that the lubricating oil is adsorbed on the sponge 6. After the sponge 6 adsorbs the lubricating oil, the pores on the sponge 6 are filled, so that the lubricating oil flows in the pores of the sponge 6. The lubricating oil is subjected to the viscous resistance and friction resistance of the pores on the sponge 6, so that the sponge 6 can not only adsorb the lubricating oil but also block the output end of the oil guiding groove 31, effectively avoiding the rapid consumption of the lubricating oil. When the sliding seat 4 partially slides in the guide sliding groove 13, the top of the sliding seat 4 can be in contact with the lower end surface of the second mounting groove 15 arranged at the bottom of the limiting guide plate 14, so that the lubricating oil adsorbed on the sponge 6 can be applied to the surface of the sliding seat 4, thereby reducing the friction between the sliding seat 4 and the inner wall of the guide sliding groove 13. The jamming phenomenon caused by the large friction between the sliding seat 4 and the guide sliding groove 13 is effectively avoided.

[0034] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the side of the guide sliding groove 13 of the guide rail device 1 is provided with a mounting table 12 for mounting the fixed seat 2. The mounting table 12 is uniformly provided with a flexible dustproof brush 21 for preventing sundries from entering the guide sliding groove 13.

[0035] In order to prevent sundries from entering the inside of the guide chute 13, the fixed seat 2 is horizontally installed in the mounting table 12, and then the flexible dust-proof brush 21 is uniformly distributed on one side of the fixed seat 2, so that the flexible dust-proof brush 21 can close the opening of the guide chute 13. The fixed seat 2 and the flexible dust-proof brush 21 cooperate to prevent sundries from entering the inside of the guide chute 13. Effectively avoid sundries falling into the inside of the guide chute 13, causing the sliding seat 4 to be unable to move normally, further avoid the sliding seat 4 to appear the jam phenomenon. In addition, avoid the impurities to accumulate in the inside of the guide chute 13, cause the inconvenient problem of cleaning.

[0036] As shown in Figure 3 and Figure 4 , the limiting guide plates 14 on the side walls of the guide chute 13 are all inclined downward;

[0037] An arc-shaped guide groove 17 for preventing the sliding seat 4 from moving left and right is formed on one side of the bottom of the guide chute 13.

[0038] In order to prevent the sliding seat 4 from sliding in the guide chute 13, the limiting guide plates 14 are inclined downward on the side walls of the guide chute 13, so that the limiting guide plates 14 are adapted to the two sides of the sliding seat 4, effectively preventing the sliding seat 4 from moving longitudinally. An arc-shaped guide groove 17 adapted to the bottom of the sliding seat 4 is formed on the bottom of one side of the guide chute 13, so that the arc-shaped guide groove 17 limits the horizontal direction of the sliding seat 4, effectively preventing the sliding seat 4 from moving when sliding in the guide chute 13. Thus, the stability of the sliding seat 4 is ensured.

[0039] As shown in Figure 3 and Figure 6 , the upper end surface of the mounting table 12 is provided with an oil inlet hole 32 communicating with the oil storage chamber 3, and the oil inlet hole 32 is provided with a sealing plug 33 capable of sealing the oil inlet hole 32, and the sealing plug 33 is threadedly connected with the oil inlet hole 32.

[0040] Lubricating oil is added to the inside of the oil storage chamber 3 through the oil inlet hole 32, and then the sealing plug 33 is rotated to seal the oil inlet hole 32.

[0041] As shown in Figure 3 and Figure 4 , the lower end surfaces of the two sides of the guide rail device 1 are longitudinally provided with water-proof plates 18 for blocking water.

[0042] By arranging the water-proof plates 18 on the lower end surfaces of the two sides of the guide rail device 1, when the water flows along the upper end surfaces of the guide rail device 1 to the two sides, the water flows horizontally along the lower end surfaces of the two sides of the guide rail device 1. When the water flow contacts the water-proof plates 18, the water-proof plates 18 can prevent the water flow from continuing to flow, effectively preventing the water flow from entering the connecting gap between the guide rail device 1 and the roof, thereby improving the anti-seepage effect of the guide rail device 1.

[0043] As shown inFigure 3 As shown, the outer part of the guide rail device 1 is mounted with a sound insulation sleeve 5;

[0044] The side wall of the guide rail device 1 is fixed with a limiting guide plate 16 for preventing the sound insulation sleeve 5 from falling off, and the limiting guide plate 16 can be inserted into the inside of the sound insulation sleeve 5.

[0045] By mounting the sound insulation sleeve 5 on the outer part of the guide rail device 1, the sound insulation sleeve 5 can reduce the noise generated in the sunroof area, improve the quietness in the vehicle, and enhance the heat insulation effect and improve the driving comfort. In order to ensure the stability of the sound insulation sleeve 5, the limiting guide plate 16 is fixed on the side of the guide rail device 1, and then the limiting guide plate 16 is inserted into the inside of the sound insulation sleeve 5, which effectively avoids the sound insulation sleeve 5 from falling off from the outer part of the guide rail device 1. Thus, the stability of the sound insulation sleeve 5 is ensured.

[0046] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
