Description

Technical Field

[0001] The invention relates to the field of automobile sunroof brackets, and more particularly to a fixing bracket of an automobile sunroof. Background Art

[0002] A car sunroof is an openable window installed on the roof of the car. It provides passengers with additional light and ventilation, and can enhance the sense of space inside the car. The bracket of the car sunroof is an important part to ensure that the sunroof can be correctly installed on the roof and operate normally. Depending on the type of sunroof, the design of the bracket will also be different. Common car sunroofs include: outward sliding sunroof, built-in sunroof (panoramic sunroof), pop-up sunroof, fixed sunroof, tilt / sliding combination sunroof.

[0003] For a fixed sunroof that cannot be opened, although no moving parts are required, a sturdy frame is still needed to support the glass and ensure good sealing with the car body. After a long period of use, the car will experience various road conditions, especially on rugged roads. The car will experience bumps and severe vibrations. In this case, the bolts, nuts and other fasteners on the fixed bracket will gradually loosen due to the vibration, thereby weakening the connection between the bracket and the car body. In severe cases, it may affect the safety and stability of the sunroof. At the same time, it will cause a gap between the sunroof and the car body. The sealing strip cannot be effectively squeezed at the joint, thereby reducing the sealing effect. Summary of the invention

[0009] Furthermore, an elastic airbag is fixedly installed on the bottom of one group of top plates, and the elastic airbag is arranged in contact with the top of the adjacent bottom plate. A telescopic tube is fixedly installed on the top of the top plate, and the bottom end of the telescopic tube passes through the top plate and is fixedly installed with the air inlet end of the elastic airbag. An intake pipe is fixedly installed on the top of the telescopic tube, and the top end of the intake pipe passes through the bottom frame and is flush with the top of the bottom frame. Sealing rings are sleeved on the outer walls of the bottom frame and the top frame, and a skylight glass is inserted into the top of the top frame.

[0010] Furthermore, a water storage tank is provided at the top of the bottom frame, and a collection frame can be removably installed on one side of each group of the bottom plate, and a drainage pipe can be removably installed on the top of each group of the collection frame, and the top end of each group of the drainage pipe passes through the bottom frame to the bottom wall of the inner cavity of the water storage tank.

[0011] Furthermore, a connecting block is evenly fixedly installed on the bottom of the bottom frame, a nut two is evenly fixedly installed on one side of each group of the connecting blocks, a threaded groove matching the adjacent nut two is opened on each group of the connecting blocks, a fixing rod is provided in the inner cavity of each group of the threaded grooves, each group of the fixing rods is slidably installed with the bottom of the bottom frame, a telescopic spring is fixedly installed at one end of each group of the fixing rods, a fixing plate is fixedly installed at the other end of each group of the telescopic springs, and each group of the fixing plates is fixedly installed with the bottom of the bottom frame.

[0012] Furthermore, each group of the fixing rods is provided with a ball at one end away from the adjacent telescopic spring, and each group of the balls is rollingly mounted on one end of the adjacent fixing rod.

[0013] Furthermore, a mounting rod is provided in the return spring near one side of the elastic airbag, and the top end of the mounting rod is fixedly mounted to the adjacent top plate.

[0014] Furthermore, a clamping block is rotatably mounted on the bottom end of each group of the mounting rods, and a through groove matched with the clamping block is provided on the bottom plate of each group.

[0015] Furthermore, an exhaust hole is provided on the bottom plate at one side close to the elastic airbag, and the top end of the exhaust hole is directly opposite to the air outlet end of the bottom of the elastic airbag.

[0017] Furthermore, the cross-sectional diameter of the fixing rod is smaller than the diameter of the threaded hole on the second nut.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) With the cooperation of the return spring, the present invention can realize the upward movement of the round block through the slot to be mounted on the bottom end of the nut 1. At this time, the nut 1 can be limited and prevented from rotating, so that it can remain in a tightened state. This avoids the situation where the bolts, nuts and other fasteners on the fixed bracket gradually loosen due to the long-term accumulated bumps and vibrations after long-term use of the car. This can effectively improve the connection firmness between the bracket and the car body, and avoid the situation where a gap is generated between the sunroof and the car body due to looseness, making it impossible for the sealing strip to be effectively squeezed at the joint, thereby effectively improving the sealing effect.

[0020] (2) This solution expels the gas inside the elastic airbag by squeezing it. In a sealed state, the elastic airbag will continue to be compressed. When there is a gap leak, the gas will flow into the gap between the bottom frame and the top frame. The elastic airbag's own suction force will absorb the gas between the bottom frame and the top frame and gradually restore the initial state. This can serve as a warning to the user and facilitate the user to observe the real-time sealing status and perform maintenance in a timely manner, thus avoiding the situation where water leakage is not discovered in time, effectively avoiding unnecessary losses, and thus effectively improving the use effect.

[0021] (3) In the present solution, when there is a gap between the sealing ring on the top frame and the connection between the car, rainwater will flow through the gap into the space between the bottom frame and the top frame on rainy days. By setting up the inner cavity of the water storage tank, rainwater can be pre-collected to avoid rainwater flowing directly into the car through the gap, causing unnecessary losses. Rainwater in the water storage tank will flow into the collection frame through various sets of drainage pipes for collection, which can buy enough time for users to rush to the repair shop for repair in time, which can effectively improve the use effect and avoid rainwater flowing directly into the car, causing unnecessary losses.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 7 A fixing bracket of a car sunroof comprises a bottom frame 1, a top frame 2 is inserted on the top of the bottom frame 1, a sealing sleeve 3 is sleeved on the outer wall of the top frame 2, and the sealing sleeve 3 is contacted with the top frame 2 and the bottom frame 1 to form a sealing state;

[0033] Also includes:

[0034] The anti-loosening component includes a bottom plate 4 uniformly fixedly installed on the bottom of the bottom frame 1, a top plate 5 is slidably installed on each group of bottom plates 4, a reset spring 6 is fixedly installed between each group of top plates 5 and the adjacent bottom plates 4, bolts 7 are uniformly contacted with the outer side of the sealing sleeve 3, each group of bolts 7 is fixedly installed with the top frame 2, each group of bolts 7 is movably inserted on the bottom frame 1, a nut 8 is threadedly installed on the bottom end of each group of bolts 7, each group of nuts 8 is contacted with the bottom of the bottom frame 1, a round block 9 is fixedly installed on the top of each group of top plates 5, and each group of round blocks 9 is provided with a slot 10 matched with the adjacent nut 8 and bolt 7.

[0035] An elastic airbag 16 is fixedly installed at the bottom of one group of top plates 5, and the elastic airbag 16 is arranged in contact with the top of the adjacent bottom plate 4. A telescopic tube 17 is fixedly installed on the top of the top plate 5. The bottom end of the telescopic tube 17 passes through the top plate 5 and is fixedly installed with the air inlet end of the elastic airbag 16. An air intake pipe 18 is fixedly installed on the top of the telescopic tube 17. The top end of the air intake pipe 18 passes through the bottom frame 1 and is flush with the top of the bottom frame 1. Sealing rings 15 are sleeved on the outer walls of the bottom frame 1 and the top frame 2, and a skylight glass 14 is inserted into the top of the top frame 2.

[0036] A square opening for installing a sunroof is provided on the top of the car. First, glue is applied to the top inner wall of the top frame 2, and then the sunroof glass 14 is inserted into the inner wall of the top frame 2. The sunroof glass 14 is fixedly installed in the top frame 2 by glue. Then, the sealing sleeve 3 is sleeved on the side wall of the top frame 2 and placed in each group of bolts 7. In the initial state, when the nut 8 is not installed, the round block 9 will contact the bottom of the bottom frame 1. When the bottom frame 1 and the top frame 2 are installed together, the bottom frame 1 and the top frame 2 are clamped on the frame of the top of the car, and the top plate 5 is pulled downward. The top plate 5 moves downward, squeezing the reset spring 6. The top plate 5 moves downward, driving the round block 9 on its top to move downward synchronously. When the round block 9 is away from the bottom of the bottom frame 1, the top frame 2 is inserted on the top of the bottom frame 1. At this time, each group of bolts 7 penetrates the bottom frame 1 and moves between the bottom frame 1 and the top plate 5. A distance between the round block 9 and the bottom end of the bolt 7 is left to allow a nut 8 to be placed. Then, the nut 8 is inserted between the round block 9 and the bolt 7 from one side, and the nut 8 is rotated and tightened on the bolt 7 by an external tool. At this time, the bottom frame 2 can be fixed. The frame 1 and the top frame 2 are fixedly installed together and snapped onto the skeleton of the top of the car. The bottom frame 1 and the top frame 2 can be sealed with the top of the car through the sealing ring 15. The bottom frame 1 and the top frame 2 can be sealed through the sealing sleeve 3. The pressure applied to the top plate 5 is cancelled. Under the action of the reset spring 6, the reset spring 6 restores the initial state to push the top plate 5 to move upward. When the top plate 5 moves upward, it will drive the round block 9 on the top to move upward synchronously. By setting the card slot 10 on the round block 9, the round block 9 can be moved upward. It is arranged on the bottom end of the nut 8 and the bolt 7, and at this time, the nut 8 can be limited, which can prevent the nut 8 from rotating and keep it in a tightened state, avoiding the situation that the bolts 7, nuts 8 and other fasteners on the fixing bracket are gradually loosened after a long period of accumulated bumps and vibrations after long-term use of the car, which can effectively improve the connection firmness between the bracket and the car body, and avoid the situation that the looseness causes a gap between the sunroof and the car body, so that the sealing strip cannot be effectively squeezed at the joint, thereby effectively improving the sealing effect;

[0037] By setting the telescopic tube 17, the bolt 7 will shrink and stretch accordingly when the top plate 5 moves up and down. After the bottom frame 1 and the top frame 2 are connected to the square opening on the top of the car, the sealing ring 15 and the sealing sleeve 3 are set to form a sealed state between the bottom frame 1 and the top frame 2. The staff can squeeze the elastic airbag 16 from both sides of the elastic airbag 16, and the gas in the inner cavity of the elastic airbag 16 will be discharged through the air outlet. When the pressure applied to the elastic airbag 16 is cancelled, under the action of the elastic airbag 16, the elastic airbag 16 returns to its initial state and absorbs the gas between the bottom frame 1 and the top frame 2 through the telescopic tube 17 and the suction pipe 18. Since the bottom frame 1 and the top frame 2 are in a sealed state at this time, but not in a negative pressure state, the elastic airbag 16 can still absorb some of the bottom The elastic airbag 16 can be pressed repeatedly to make its compressed state more obvious, which is convenient for users to observe. The elastic airbag 16 is in a compressed state and will be away from the top of the bottom plate 4. When there is a gap and air leakage between the connection between the bottom frame 1 and the top frame 2 and the car, the gas will flow into the space between the bottom frame 1 and the top frame 2. At the same time, under the action of the elastic airbag 16, the suction force of the elastic airbag 16 itself will absorb the gas between the bottom frame 1 and the top frame 2 and gradually restore the initial state, which can warn the user and facilitate the user to observe the real-time sealing state and perform maintenance in time, thus avoiding the situation where water leakage is not discovered in time, and effectively avoiding unnecessary losses, thereby effectively improving the use effect.

[0038] like Figure 2 and Figure 3 As shown, a water storage tank 20 is provided at the top of the bottom frame 1, and a collecting frame 21 can be detachably installed on one side of each group of bottom plates 4. A drain pipe 22 can be detachably installed on the top of each group of collecting frames 21, and the top end of each group of drain pipes 22 passes through the bottom frame 1 to the bottom wall of the inner cavity of the water storage tank 20.

[0039] When there is a gap between the sealing ring 15 on the top frame 2 and the connection between the car, when it rains, rainwater will flow through the gap between the bottom frame 1 and the top frame 2, and the rainwater will flow into the inner cavity of the water storage tank 20. The setting of the inner cavity of the water storage tank 20 can collect rainwater, which plays a role of pre-collection, and can avoid rainwater from directly flowing into the car through the gap, causing unnecessary losses. The rainwater in the water storage tank 20 will flow into the collection frame 21 through each group of drainage pipes 22 for collection, which can buy enough time for the user to rush to the repair shop for repair in time, which can effectively improve the use effect and avoid the situation where rainwater directly flows into the car and causes unnecessary losses. The collection frame 21 is detachably arranged with the drainage pipe 22 and the bottom plate 4, so that the collection frame 21 can be disassembled and the rainwater inside it can be taken out and cleaned.

[0040] like Figure 5 and Figure 7 As shown, the bottom of the bottom frame 1 is evenly fixed with connecting blocks 23, and one side of each group of connecting blocks 23 is evenly fixed with nuts 25. Each group of connecting blocks 23 is provided with threaded grooves 24 that are compatible with adjacent nuts 25. The inner cavity of each group of threaded grooves 24 is provided with fixing rods 26. Each group of fixing rods 26 is slidably installed with the bottom of the bottom frame 1, and one end of each group of fixing rods 26 is fixedly installed with a telescopic spring 28, and the other end of each group of telescopic springs 28 is fixedly installed with a fixing plate 29, and each group of fixing plates 29 is fixedly installed with the bottom of the bottom frame 1.

[0041] A ball 27 is provided at one end of each group of fixing rods 26 away from the adjacent telescopic spring 28 , and each group of ball 27 is rollingly mounted on one end of the adjacent fixing rod 26 .

[0042] When fixing and installing the bottom frame 1, align the threaded groove 24 on the connecting block 23 with the mounting hole on the connecting piece in the square opening on the top of the car, and then squeeze the ball 27. The ball 27 will drive the fixing rod 26 to move at the bottom of the bottom frame 1 and squeeze the telescopic spring 28. After the threaded groove 24 is aligned with the mounting hole on the connecting piece, the pressure applied to the fixing rod 26 is cancelled. Under the action of the telescopic spring 28, the telescopic spring 28 returns to its initial state and pushes the fixing rod 26 to move to its initial position. At this time, the fixing rod 26 can drive the ball 27 to move into the mounting hole on the connecting piece. When fixing and installing the bottom frame 1 and the connecting piece of the car, insert the screw into the connecting piece. The ball 27 is then squeezed into the mounting hole, and then one end of the screw is used to squeeze the ball 27. The ball 27 is squeezed and will continue to squeeze the fixing rod 26. The fixing rod 26 is squeezed and moved to squeeze the telescopic spring 28. When the screw moves into the inner cavity of the threaded groove 24 and then enters the threaded hole of the inner cavity of the nut 25, the screw can be rotated to achieve fixed installation with the nut 25. At this time, the bottom frame 1 can be fixedly installed on the connecting parts of the car, and the fixing effect can be further effectively improved. Through the setting of the fixing rod 26, the bottom frame 1 can be pre-fixed with the connecting parts on the car, which reduces manpower and is convenient for users to use screws for fixing, which can effectively improve work efficiency.

[0043] like Figure 3 and Figure 5 As shown, a mounting rod 11 is provided in the return spring 6 near the elastic airbag 16 , and the top end of the mounting rod 11 is fixedly mounted to the adjacent top plate 5 .

[0044] A clamping block 12 is rotatably mounted on the bottom end of each group of mounting rods 11 , and a through slot 13 matched with the clamping block 12 is formed on each group of bottom plates 4 .

[0045] The card block 12 is rotated to align with the through slot 13. In the process of pressing the top plate 5 to move downward and squeeze the reset spring 6, the top plate 5 moves downward and drives the mounting rod 11 and the card block 12 to move synchronously. When the card block 12 moves to the top position of the through slot 13, the top plate 5 continues to move downward and drives the card block 12 to move downward into the inner cavity of the through slot 13 through the mounting rod 11. When the card block 12 moves downward and moves out of the bottom of the through slot 13, the card block 12 is rotated so that it is not aligned with the through slot 13. At this time, the pressure applied to the top plate 5 is cancelled. Under the action of the reset spring 6, the reset When the spring 6 returns to its initial state, it will push the top plate 5 to move upward so that the top of the block 12 contacts the bottom of the bottom plate 4. At this time, the top plate 5 cannot move upward. The setting of the block 12 can realize the limit fixation of the top plate 5, which can facilitate the installation of the nut 8 on the bolt 7. The user does not need to apply pressure to the top plate 5 all the time, which reduces manpower and effectively improves work efficiency. After the nut 8 is installed, the block 12 is rotated again to align with the through groove 13, so that the reset spring 6 can drive the top plate 5 to move upward to restore the initial state, and make the round block 9 stuck on the outside of the nut 8.

[0046] like Figure 5 As shown, an exhaust hole 19 is opened on the bottom plate 4 near the elastic airbag 16 , and the top of the exhaust hole 19 is opposite to the air outlet end of the bottom of the elastic airbag 16 .

[0047] Each group of collection frames 21 is a visualization material setting.

[0048] The cross-sectional diameter of the fixing rod 26 is smaller than the diameter of the threaded hole on the nut 25 .

[0049] The exhaust hole 19 is arranged just below the bottom air outlet of the elastic airbag 16. When the top plate 5 moves downward, the top plate 5 will squeeze the elastic airbag 16. The air outlet of the elastic airbag 16 will be exhausted through the exhaust hole 19 and will not be affected. By setting the collection frame 21 as a visual material, the user can observe the situation in the collection frame 21 and disassemble and clean the collection frame 21 according to the situation of rainwater in the collection frame 21.

[0050] Working principle: first, squeeze each group of balls 27 and fixing rods 26, and insert them into the mounting holes on the connecting piece in the square opening on the top of the car to pre-install the bottom frame 1, and then squeeze the balls 27 through the screw to make the fixing rod 26 move out of the threaded groove 24, so that the screw can be rotated and fixedly connected with the nut 25, and the bottom frame 1 is fixedly installed on the connecting piece in the square opening of the car, and the sunroof glass 14 is fixedly installed on the top of the bottom frame 1 by glue, and then the sealing sleeve 3 is sleeved on the outside of the top frame 2 from below, and each group of top plates 5 is pulled downward to squeeze the reset spring 6, and the block 12 is stuck at the bottom of the through groove 13 to fix the top plate 5 after moving downward, and then the top frame 2 and the fixed bottom frame 1 are aligned and clamped on the frame of the car, and each group of bolts 7 will be inserted into the bottom frame 1, and then the nut 1 8 is used to be installed at the bottom end of each group of bolts 7 to fix the bottom frame 1 and the top frame 2 to the frame of the car. , and then rotate the block 12 to align with the through groove 13 to reset the top plate 5, so that the round block 9 is sleeved on the outside of the nut 8 for limiting. At this time, through the cooperation of the sealing ring 15 and the sealing sleeve 3, a sealed state can be formed between the bottom frame 1 and the top frame 2 and the top of the car. Then, the elastic airbag 16 is squeezed to exhaust the gas, so that the elastic airbag 16 cannot absorb gas and is in a compressed state, which is convenient for users to observe. When there is a gap leak, the elastic airbag 16 will return to its initial state. When rainwater flows into the bottom frame 1 and the top frame 2 through the top gap, the rainwater will flow in the water tank 20 through the drain pipe 22 and flow into the collection frame 21. It can be intuitively seen whether there is rainwater through the collection frame 21, so as to judge whether there is a gap, thereby facilitating the user to go for maintenance. A transparent frame can be detachably installed at the bottom of the bottom frame 1, and it is integrally sleeved on the outside of all parts at the bottom of the bottom frame 1 to enhance the overall aesthetics.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
