[0024] The embodiment of the utility model provides a rear beam structure of a sunroof of an automobile.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including a sunroof rear crossbeam body 1, both sides of the sunroof rear crossbeam body 1 are fixedly connected with installation boxes 2, the opposite sides of the two installation boxes 2 are fixedly connected with guide rail members 3, one side of the two installation boxes 2 is provided with a triangular block 15, an electric push rod 18 is provided between the two triangular blocks 15, a transmission block 14 is provided on one side of the triangular block 15, one side of the transmission block 14 is fixedly connected with a guide box 8, both ends of the guide box 8 are respectively fixedly connected with a return spring 9 and a rubber member 7, the rubber member 7 is arranged inside the guide rail member 3, the top and one side of the guide box 8 are respectively fixedly connected with a first hose 10 and a second hose 13, and a pressure relief valve 6 is fixedly connected between one end of the second hose 13 and the guide rail member 3.

[0026] When the utility model is in use: installation boxes 2 are fixedly connected to both sides of the sunroof rear beam body 1, guide rail parts 3 are fixedly connected to the opposite sides of the two installation boxes 2, and the sunroof rear beam body 1, two installation boxes 2 and two guide rail parts 3 constitute a sunroof rear beam structure. The working details can refer to the existing patent application number: 201920244863.1 disclosed a car sunroof rear beam.

[0027] A return spring 9 is fixedly connected to the interior of the installation box 2, and one end of the return spring 9 is fixedly connected to the guide box 8. One end of the rubber part 7 installed in the guide box 8 passes through the installation box 2 and the guide rail part 3 and extends to the interior of the guide rail part 3, so that the rubber part 7 fixedly installed at one end of the guide box 8 is set to the interior of the guide rail part 3. When the skylight is guided and moved between the two guide rail parts 3 by the two guide rail parts 3, the skylight will squeeze the rubber part 7 that can be elastically deformed. After the rubber part 7 is deformed, the internal hydraulic pressure of the guide box 8 increases, and a second hose 13 is fixedly connected to one side of the guide box 8, and one end of the second hose 13 is fixedly connected to the pressure relief valve 6. Therefore, the lubricating oil in the guide box 8 enters the interior of the pressure relief valve 6 through the second hose 13. Since the opening end of the pressure relief valve 6 is arranged in the interior of the guide rail part 3, the lubricating oil will open the pressure relief valve 6 and then enter the interior of the guide rail part 3. The lubricating oil lubricates the contact position between the skylight and the guide rail part 3, and reduces the wear rate of the guide rail part 3 and the skylight.

[0028] An absorbent cotton strip 4 is fixedly connected to the bottom of the inner cavity of the guide member 3, and multiple arc-shaped absorbent cottons 5 fixedly connected to the outside of the absorbent cotton strip 4 are all fixedly connected to the guide member 3. Therefore, after the lubricating oil is absorbed by the absorbent cotton strip 4 at the bottom of the inner cavity of the guide member 3, the multiple arc-shaped absorbent cottons 5 absorb the lubricating oil inside the absorbent cotton strip 4, and the lubricating oil is guided to multiple positions inside the guide member 3 by the multiple arc-shaped absorbent cottons 5 distributed at various positions inside the guide member 3, ensuring comprehensive lubrication of the contact position between the guide member 3 and the skylight, and dispersing the lubricating oil to prevent the lubricating oil from leaving the inside of the guide member 3 and causing pollution.

[0029] A liquid storage tank 11 for storing lubricating oil is fixedly connected inside the installation box 2, and a one-way valve 12 is fixedly connected to the bottom of the liquid storage tank 11. The one-way valve 12 is fixedly connected to the first hose 10 fixedly connected to the top of the guide box 8. When the skylight no longer squeezes the rubber part 7, the rubber part 7 recovers its shape. At this time, the lubricating oil inside the liquid storage tank 11 enters the guide box 8 through the one-way valve 12 and the first hose 10 under the influence of gravity and hydraulic pressure for storage. The lubricating oil flowing under the influence of gravity is not enough to flush the pressure relief valve 6 and is discharged from the pressure relief valve 6. After the skylight is reset, the liquid storage tank 11, the one-way valve 12, the first hose 10, the guide box 8 and the rubber part 7 cooperate to automatically fill the inside of the rubber part 7. The one-way valve 12 has the characteristic of only being able to drain water in one direction, so the lubricating oil will not flow back into the liquid storage tank 11 after the rubber part 7 is deformed.

[0030] The user controls the electric push rod 18 to work, and the electric push rod 18 pushes the moving plate 17 fixedly connected at the extension end to move. The two triangular blocks 15 are fixedly connected to the transmission plate 16, and the two transmission plates 16 are fixedly connected to the moving plate 17, so the moving plate 17 pushes the two triangular blocks 15 through the two transmission plates 16, and the two triangular blocks 15 move the guide box 8. An arc surface 19 is provided on one side of the transmission block 14, and the inclined surface of the triangular block 15 faces the arc surface 19. The arc surface 19 reduces the friction between the transmission block 14 and the triangular block 15, so when the triangular triangular block 15 moves the guide box 8, the triangular Block 15 lifts the transmission block 14 to make the transmission block 14 away from the guide rail member 3. The guide box 8 fixedly connected on one side of the transmission block 14 only penetrates the installation box 2 and the guide rail member 3, and is not fixed to the installation box 2 and the guide rail member 3. Therefore, the guide box 8 fixedly connected to the transmission block 14 moves in the direction away from the guide rail member 3, and finally the rubber member 7 fixedly connected to the guide box 8 leaves the inside of the guide rail member 3, stopping the movement of the sunroof and adding lubricating oil to the inside of the guide rail member 3, reducing the waste of lubricating oil. The user can control the electric push rod 18 to achieve the purpose of controlling the time of adding lubricating oil to the contact position between the guide rail member 3 and the sunroof.

[0031] Limiting grooves 20 are provided on both sides of the sunroof rear crossbeam body 1 and on one side of the two installation boxes 2 close to the sunroof rear crossbeam body 1. The moving plate 17 passes through a plurality of limiting grooves 20, so that the movement of the moving plate 17 is supported and limited by the sunroof rear crossbeam body 1 and the installation box 2, thereby ensuring the stability of the movement of the moving plate 17.

[0032] Both the first hose 10 and the second hose 13 can be deformed to meet the movement requirements of the guide box 8. When the electric push rod 18 drives the moving plate 17 to reset, the triangular block 15 resets, and the rebounding reset spring 9 pushes the guide box 8 fixed at one end to reset, and the rubber part 7 returns to the inside of the guide rail part 3.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
