[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] Reference Figure 1-4As shown, a deformation-resistant automobile sunroof guide rail comprises a guide rail 1 made of titanium alloy material, a top plate 2 fixed to the top of the guide rail 1, and a plurality of mounting holes equidistantly opened on the top plate 2, wherein bolts 3 are penetrated through the threads in the mounting holes;

[0021] The guide rail 1 is made of titanium alloy material, which is a material that is not easily deformed, so that the guide rail 1 itself has excellent resistance to deformation;

[0022] By setting the bolt 3, when the guide rail 1 is placed on the roof, the bolt 3 is then threaded into the mounting hole and the bolt 3 is threadedly connected to the roof, so that the guide rail 1 and the top plate 2 can be fixed as a whole.

[0023] Further, refer to Figure 2-3 As shown, it is worth noting that a protective mechanism for preventing the bolt 3 from corroding is also included;

[0024] The protection mechanism includes a locking frame 6 fixed on the top surface of the top plate 2 in a rectangular frame shape and a protection cover 4 detachably arranged inside the locking frame 6, a rubber pad 5 that fits the top surface of the top plate 2 is glued on the bottom surface of the protection cover 4, and a plurality of bolts 3 are located inside the protection cover 4;

[0025] By setting the protective cover 4 and the rubber pad 5, after the guide rail 1 and the top plate 2 are fixed to the roof as a whole by using the bolts 3, the protective cover 4 is passed through the inner side of the locking frame 6, and a plurality of bolts 3 are covered at one time, so that the protective cover 4 can effectively seal and protect the bolts 3, and prevent the bolts 3 from being affected by the environment outside the vehicle and rusting, thereby affecting the use effect.

[0026] Further, refer to Figure 2-4 As shown, it is worth noting that movable grooves 7 are provided on the inner walls on both sides of the locking frame 6, and extrusion-type locking members are provided in the movable grooves 7, and air supply members matching with the extrusion-type locking members are provided on the outer side of the locking frame 6;

[0027] The extrusion type locking member includes an extrusion block 8 in a right-angled trapezoidal shape and slidably arranged in the opening of the locking frame 6, a return spring 10 is fixed between the extrusion block 8 and the innermost inner wall of the movable groove 7, a locking groove 9 corresponding to the movable groove 7 is opened on the side wall of the protective cover 4, the longitudinal section of the locking groove 9 is in a right-angled trapezoidal shape, and the oblique inner wall of the locking groove 9 corresponds to the oblique side of the extrusion block 8;

[0028] By setting the air supply part and the extrusion type locking part, after the protective cover 4 is penetrated inside the locking frame 6, the air supply part is used to simultaneously inject gas into the movable grooves 7 on the inner walls of both sides of the locking frame 6, so that the extrusion blocks 8 in the two movable grooves 7 are simultaneously slid into the corresponding inner sides of the locking grooves 9 by the air pressure, and then the extrusion blocks 8 are squeezed by the oblique edges of the locking grooves 9 toward the oblique inner walls, which can form downward pressure on the protective cover 4 from both sides, increase the fit between the rubber pad 5 and the top plate 2, and improve the sealing protection effect of the protective cover 4 on the bolts 3;

[0029] During this time, when the extrusion block 8 slides into the inner side of the locking groove 9 under the air pressure, the extrusion block 8 can simultaneously stretch the reset spring 10 to deform, and then use the elastic force of the reset spring 10. When the air supply part is used to release the internal air pressure of the movable groove 7, the pressure on the extrusion block 8 is reduced, and the extrusion block 8 can be quickly reset under the elastic force of the reset spring 10, shrinking the inner side of the movable groove 7 for secondary use.

[0030] Further, refer to Figure 1-3 As shown, it is worth noting that the air supply part includes an air injection pipe 11 arranged in a C-shape outside the locking frame 6, the two ends of the air injection pipe 11 are respectively inserted into the two movable grooves 7, and the middle part of the air injection pipe 11 is fixedly connected with a vent nozzle 12, and the vent nozzle 12 has a valve core built in;

[0031] The vent nozzle 12 is connected to a micro air pump, and then the micro air pump is used to inject gas into the gas injection pipe 11, so that the gas is split and injected into the inner side of the two movable grooves 7 by the gas injection pipe 11, so as to achieve the pressurization effect of the extrusion block 8 inside the two movable grooves 7;

[0032] And by using the valve core, the gas inputted into the vent nozzle 12 by the micro air pump can flow in one direction, so as to avoid gas leakage from the vent nozzle 12 when the gas injection is stopped. Later, the inside of the gas injection tube 11 can be deflated by only using a ejector pin to squeeze the valve core.

[0033] Further, refer to Figure 1 As shown, it is worth noting that the open end of the vent nozzle 12 is threadedly connected with a sealing cap 13;

[0034] By setting the sealing cap 13, after the micro air pump is used to complete the air injection operation inside the air injection pipe 11, the sealing cap 13 can be threadedly added to the open end of the vent nozzle 12, thereby sealing the inside of the vent nozzle 12 to prevent dust and impurities from entering and causing blockage inside the vent nozzle 12.
