Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive sunroof technology, specifically to an automotive sunroof guide frame. Background Technology
[0002] With the development of the automotive industry, more and more cars are equipped with sunroofs. Car sunroofs can effectively circulate air inside the car, increase the intake of fresh air, and bring a healthy and comfortable experience to car owners. At the same time, car windows can also broaden the field of vision, making the people inside the car feel more comfortable. The car sunroof guide frame is the core structural component of the car sunroof system, which is equivalent to the "skeleton + track system" of the sunroof. Its main function is to provide a precise guide path for the opening, closing, sliding or tilting of the sunroof glass (or sunshade). It also undertakes the functions of installing and fixing sunroof components, bearing weight and sealing connections. It is a key structure to ensure the smooth operation, stability and durability of the sunroof.
[0003] The seal between the sunroof and the car body / building frame is not absolutely waterproof. During rain or car washes, a small amount of rainwater can seep into the sliding track through gaps in the sealing strips and the sunroof's opening gaps. If the anti-rust coating on the slider surface is scratched due to friction (wear from contact with the track during sunroof movement), accumulated water will directly contact the base metal. Impurities in the rainwater (such as dust and acidic substances from car exhaust) will accelerate electrochemical corrosion, forming red rust or white spots. Rust will cause the slider to enlarge (rust buildup), reducing the clearance between it and the track, leading to sliding jams (such as the sunroof getting stuck halfway open), or even complete blockage.

[0013] (III) Beneficial Effects
[0014] This utility model provides a guide frame for an automotive sunroof, which has the following advantages:
[0015] 1. In this utility model, when the support bracket and its top sunroof glass are closed (i.e., moving towards the drain pipe 2), the sliding end of the support bracket pulls the rack 2 to move linearly towards the drain pipe 2. The rack 2 drives the rack 1 to move linearly in the opposite direction through the gear. At this time, the insert rod moves into the sleeve rod and pushes the gas inside the sleeve rod to be discharged through the one-way exhaust valve. After passing through the hose, it is finally sprayed out through the jet pipe and blown towards the bottom wall of the slide groove, so that the water flows to the drain outlet, then enters the drainage groove, and is finally discharged through the drain pipe. The drain pipe generally extends downward along the A-pillar, C-pillar and other structures of the vehicle body, and finally connects to the drain outlet at the bottom of the vehicle to discharge the water outside the vehicle.
[0016] 2. In this utility model, the sliding end of the support bracket will drive the hose to move during the linear movement. Therefore, the purpose of setting the support ring is to limit the hose within a certain range and prevent it from interfering with other components during the movement. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Please see Figures 1 to 6This utility model provides a technical solution: a car sunroof guide frame, including a main frame 1 in the shape of a U-shape, two drainage channels 101 and two sliding channels 102 opened on the top of the main frame 1, a sliding channel 102 and a drainage channel 101 distributed on each side of the main frame 1, and a drain outlet 103 connected between the sliding channel 102 and the drainage channel 101. A support bracket 3 is slidably installed on the top of the main frame 1. Both ends of the support bracket 3 form inverted T-shaped sliding ends 301, which are located inside the sliding channels 102. A sleeve rod 9 and an insert rod 12 slidably fitted inside the sleeve rod 9 are fixedly connected to the end of the inner wall of the sliding channel 102. A transmission component is provided between the end of the insert rod 12 and the sliding end 301. A one-way air intake valve 11 and a one-way air exhaust valve 10 are connected to the sleeve rod 9. A hose 5 is fixedly connected to the end of the one-way air exhaust valve 10, and an air jet pipe 4 is fixedly connected to the other end of the hose 5. The nozzle of the air jet pipe 4 is aligned with the inner bottom wall of the sliding channel 102.
[0026] The support bracket 3 needs to be connected to an external power mechanism (not shown in the figure). The power mechanism drives the support bracket 3 to make linear displacement. During the process of the support bracket 3 moving towards the drain pipe 2, the transmission component connected to the sliding end 301 drives the insertion rod 12 to move towards the inside of the sleeve rod 9, pushing the gas inside the sleeve rod 9 to be discharged through the one-way exhaust valve 10, and finally sprayed onto the slide groove 102 through the jet pipe 4.
[0027] The power mechanism can be driven by "screw rotation + nut linear motion", which has strong load-bearing capacity and high motion precision. It is suitable for panoramic sunroofs or heavy-duty sunroofs. This is existing technology, so it will not be described in detail.
[0028] Reference Figure 4 The transmission assembly includes a gear 6 rotatably disposed between the inner walls of the slide groove 102, and racks 7 and 8 meshing with the gear 6 and distributed on the upper and lower sides. Rack 7 is fixedly connected to the end of the insert rod 12, and rack 8 is fixedly connected to the end of the sliding end 301.
[0029] When the support bracket 3 and its top sunroof glass are closed (i.e., moving towards the drain pipe 2), the sliding end 301 at the end of the support bracket 3 pulls the rack 8 to move linearly towards the drain pipe 2. The rack 8 drives the rack 7 to move linearly in the opposite direction through the gear 6. At this time, the insert rod 12 moves into the sleeve rod 9 and pushes the gas inside the sleeve rod 9 to be discharged through the one-way exhaust valve 10. After passing through the hose 5, it is finally sprayed out through the jet pipe 4 and blown towards the bottom wall of the slide groove 102, causing the accumulated water to flow to the drain outlet 103, then into the drain groove 101, and finally discharged through the drain pipe 2. The drain pipe 2 generally extends downward along the A-pillar, C-pillar and other structures of the vehicle body, and finally connects to the drain outlet at the bottom of the vehicle to discharge the water outside the vehicle.
[0030] Reference Figure 3The bottom wall of the drain outlet 103 is an inclined plane, and the end of the drain outlet 103 near the drainage trough 101 is lower than the end near the slide trough 102.
[0031] The drain outlet 103 is a key channel connecting the "slide 102" and the "drainage channel 101". The design of the sloping bottom wall is essentially to provide a clear direction of gravity flow for the accumulated water.
[0032] Since the end of the drain outlet 103 closer to the drainage trough 101 is lower, the water in the chute 102 (including the water blown by the jet pipe 4) will naturally flow to the "lower side" (the direction of the drainage trough 101) under the action of gravity, avoiding water stagnation on the bottom wall of the drain outlet 103.
[0033] Reference Figure 1 and Figure 3 The support bracket 3 has multiple through holes 302 that are evenly distributed.
[0034] Place the sunroof on the support bracket 3, aligning the through holes 302 on the support bracket 3 with the corresponding mounting holes on the sunroof. These through holes 302 can be used to install bolts, pins, and other connectors to achieve a fixed connection between the sunroof and the support bracket 3.
[0035] Reference Figure 4 The top of the main frame 1 is fixedly connected with multiple equally spaced support rings 13, and the hose 5 is installed through the support rings 13.
[0036] The sliding end 301 of the support bracket 3 will drive the hose 5 to move during linear movement. Therefore, the purpose of setting the support ring 13 is to limit the hose 5 within a certain range and prevent it from interfering with other components during movement.
[0037] Reference Figure 1 and Figure 2 The end of the drainage trough 101 is fixedly connected to a drainage pipe 2.
[0038] The water inside the drainage channel 101 is eventually discharged through the drainage pipe 2. The drainage pipe 2 usually extends downward along the A-pillar, C-pillar and other structures of the vehicle body, and finally connects to the drainage outlet at the bottom of the vehicle to discharge the water outside the vehicle.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
