Description

Technical Field

[0001] This utility model relates to the technical field of heating duct fixing structure, and in particular to a shockproof quick-release buckle bracket for automotive heating ducts. Background Technology

[0002] Currently, existing clip brackets (such as patent publication number: CN220535353U) disclose a uniform air supply duct for automotive air conditioning. A servo motor is fixedly installed on the inner wall of the connecting bracket near the curved air duct of the automotive air conditioning system. The output end of the servo motor is fixedly installed on the connecting bracket. A connecting rod is fixedly installed on the side of the connecting bracket away from the servo motor. The connecting rod is connected to a rotating device. The rotating device has the function of rotating even after changing the angle. A hanging device is in contact with the inner wall of the curved air duct of the automotive air conditioning system. The hanging device is used to hang up dust on the inner wall of the curved air duct of the automotive air conditioning system.

[0003] In the aforementioned patent, the air duct is connected to the bracket by bolts. Bolt fixing is a rigid connection, which will directly transmit the vibration during vehicle operation to the heating duct. This can easily lead to increased vibration between the heating duct and the clip bracket, which will not only generate noise and affect the comfort of the vehicle, but also accelerate the wear and aging of the heating duct and reduce its service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shock-resistant quick-release clip bracket for automotive heater ducts. This solves the technical problem that the connection between the air duct and the bracket is a rigid connection, which directly transmits vibrations during vehicle operation to the heater duct. This can easily lead to increased vibration between the heater duct and the clip bracket, resulting in noise and affecting in-vehicle comfort.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shockproof quick-release buckle bracket for automotive heater ducts includes a support frame, a base plate, and a heater duct body. Two U-shaped clamps are slidably installed on the top of the support frame, and each U-shaped clamp has an inner pad.

[0007] One of the U-shaped clamps has a gathering soft strap at its top, and a mounting plate is fixedly installed at the top of the gathering soft strap. A buckle plate is fixedly installed at the side end of the mounting plate.

[0008] The support frame has a guide rail slider slidably installed inside. A connecting sleeve is rotatably installed on the side end of the guide rail slider. A partition plate is fixedly installed on the side end of the connecting sleeve. The partition plate has a segmented structure. Bolts are provided on both sides of the partition plate. Multiple insert rods are fixedly installed on the side end of the connecting sleeve.

[0009] Preferably, the mounting plate has a spring rod inside, and a sliding block is fixedly installed at both ends of the spring rod;

[0010] The guide rail slider is internally fitted with a positioning ring, and each side end of the positioning ring is provided with two reset push rods.

[0011] Preferably, a limiting ring is fixedly installed inside the guide rail slider, and the surface of the limiting ring is provided with multiple positioning holes;

[0012] Two threaded rods are rotatably mounted on the top of the guide rail slider, and a compression sleeve is rotatably mounted on the surface of each threaded rod;

[0013] Each of the guide rail sliders is rotatably mounted with a rotating rod at its side end, and the end of the rotating rod is connected to a threaded rod via a bevel gear.

[0014] Compared with the prior art, the present invention has the following beneficial effects;

[0015] In this invention, pulling the retractable soft strap at the top of the U-shaped clamp causes the two U-shaped clamps to slide symmetrically and compress the heating pipe body. The protrusion at the end of the buckle plate inserts into the U-shaped clamp to form a "pre-tightening force," while the spring rod pushes the sliding block to insert into the corresponding U-shaped clamp, quickly locking the two U-shaped clamps. The rubber pad on the inner side of the U-shaped clamp is a flexible buffer structure. When the U-shaped clamp is attached to the outer side of the heating pipe body, it can isolate the vibration of the heating pipe body during operation from being transmitted to the support frame, and achieve quick assembly and disassembly of the heating pipe body.

[0016] In this utility model, the partition plate has a segmented structure, which can be adapted and fixed to wire harnesses of different specifications and quantities through "combination" so that the wire harnesses are arranged in an orderly manner along the installation direction of the support frame and the base plate. Pulling the connecting sleeve causes the insertion rod to disengage from the positioning hole of the limiting ring (while simultaneously stretching the reset top rod); rotating the connecting sleeve can drive the partition plate to adjust the horizontal angle to meet the angle requirements of different wire harness directions.

Detailed Implementation

[0024] This application provides a shock-absorbing quick-release clip bracket for automotive heater ducts. This effectively solves the problem that bolted connections between the duct and the bracket, being rigid, directly transmit vibrations from vehicle operation to the heater duct, leading to increased vibration between the duct and the clip bracket. This not only generates noise but also affects in-vehicle comfort. Pulling the retractable soft strap at the top of the U-shaped clamp causes the two U-shaped clamps to symmetrically slide and compress the heater duct body. The protrusion at the end of the clip plate inserts into the U-shaped clamp to create a "pre-tightening force," while a spring rod pushes a sliding block into the corresponding U-shaped clamp, quickly locking the two U-shaped clamps. The rubber pad on the inner side of the U-shaped clamp is a flexible buffer structure. When the U-shaped clamp is against the outer side of the heater duct body, it can isolate the vibration of the heater duct body during operation from being transmitted to the support frame, and also enables quick assembly and disassembly of the heater duct body.

[0025] Example

[0026] like Figure 1 - Figure 5 As shown, the technical solution in this embodiment effectively solves the problem that the air duct is connected to the bracket by bolts. Bolt fixing is a rigid connection, which directly transmits the vibration during vehicle operation to the heating duct. This can easily lead to increased vibration between the heating duct and the clip bracket, which not only generates noise but also affects the comfort of the vehicle interior. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a shock-absorbing quick-release buckle bracket for automotive heater ducts, including a support frame 11, a base plate 12, and a heater duct body 13. Two U-shaped clamps 14 are slidably installed on the top of the support frame 11. Each U-shaped clamp 14 has a rubber pad 15 on its inner side. By rotating the bolt at the end of the base plate 12, the compression and rotation of the base plate 12 are released. The base plate 12 is rotatably connected to the support frame 11 through a bearing. By rotating the base plate 12, the base plate 12 deflects at the end of the support frame 11, adjusting the installation position. Then, by tightening the screws, the position of the base plate 12 and the support frame 11 is secured. The heater duct body 13 is placed on the top of the support frame 11. By sliding the two U-shaped clamps 14, the U-shaped clamps 14 slide symmetrically along the top of the support frame 11. The U-shaped clamps 14 and the rubber pads 15 are attached to the outer side of the heater duct body 13. The rubber pads 15 act as a barrier, reducing the transmission of vibration.

[0028] One of the U-shaped clamps 14 has a gathering soft strap 16 at its top. A mounting plate 17 is fixedly installed at the top of the gathering soft strap 16. A snap-on plate 18 is fixedly installed at the side end of the mounting plate 17. After the two U-shaped clamps 14 are pressed against the surface of the heating pipe body 13, the end of the rubber pad 15 rotates inside the U-shaped clamp 14 by pulling the gathering soft strap 16. At the same time, the mounting plate 17 is moved, so that the mounting plate 17 drives the snap-on plate 18 to engage with the other U-shaped clamp 14. Since the end of the snap-on plate 18 has a protruding structure, the mounting plate 17 drives the snap-on plate 18 to insert into the interior of the U-shaped clamp 14, forming a pre-tightening force. In addition, the spring rod 19 resets inside the mounting plate 17. The spring rod 19 pushes the two sliding blocks 21, so that the sliding blocks 21 slide along the interior of the mounting plate 17. The sliding blocks 21 are inserted into the interior of the other U-shaped clamp 14, which can quickly fix and disassemble the heating pipe body 13.

[0029] The support frame 11 has a sliding guide slide block 22 inside. A connecting sleeve 26 is rotatably installed on the side end of the guide slide block 22. A partition plate 27 is fixedly installed on the side end of the connecting sleeve 26. The partition plate 27 has a segmented structure. Bolts are provided on both sides of the partition plate 27. Multiple insert rods are fixedly installed on the side end of the connecting sleeve 26.

[0030] The mounting plate 17 is equipped with a spring rod 19 inside. Sliding blocks 21 are fixedly installed on both sides of the spring rod 19. When the spring rod 19 inside the mounting plate 17 is reset, the sliding blocks 21 are pushed to insert into the corresponding U-shaped clamps 14, and the two U-shaped clamps 14 are quickly locked to clamp the heating pipe body 13, which greatly shortens the installation time.

[0031] A positioning ring 23 is rotatably installed inside the guide rail slider 22. Two reset rods 24 are provided on the side ends of the positioning ring 23. The reset rods 24 are connected to the end of the connecting sleeve 26. By pulling the connecting sleeve 26, the connecting sleeve 26 slides inside the limiting ring 25. The connecting sleeve 26 stretches the two reset rods 24. The reset rods 24 are stretched and contracted by force. At the same time, the connecting sleeve 26 slides outward, causing the insertion rod to leave the inside of the limiting ring 25. By rotating the connecting sleeve 26, one end of the connecting sleeve 26 adjusts the partition plate 27 to rotate, adjusting the horizontal angle of the partition plate 27. At the same time, the connecting sleeve 26 adjusts the positioning ring 23 to rotate inside the guide rail slider 22 through the two reset rods 24. The partition plate 27 has a segmented structure. Different wire harnesses can be fixed by combination through the partition plate 27, so that the wire harnesses are fixed along the installation direction of the support frame 11 and the base plate 12.

[0032] A limiting ring 25 is fixedly installed inside the guide rail slider 22. The surface of the limiting ring 25 is provided with multiple positioning holes. Two reset push rods 24 apply opposite pulling force to the connecting sleeve 26, causing the connecting sleeve 26 to slide inside the guide rail slider 22. Through the guiding sliding of the connecting sleeve 26, the connecting sleeve 26 simultaneously drives the insertion rod into the interior of the limiting ring 25. Through the cooperation of the limiting ring 25 and the connecting sleeve 26, the angle between the connecting sleeve 26 and the partition plate 27 is locked.

[0033] Two threaded rods 28 are rotatably mounted on the top of the guide rail slider 22, and each threaded rod 28 has a compression sleeve 29 rotatably mounted on its surface;

[0034] Each guide rail slider 22 has a rotating rod rotatably mounted on its side end. The end of the rotating rod is connected to the threaded rod 28 through a bevel gear. By rotating the rotating rod, the threaded rod 28 rotates clockwise inside the guide rail slider 22. The rotation of the threaded rod 28 drives the extrusion sleeve 29 to slide at the top of the guide rail slider 22. The extrusion sleeve 29 presses the inner side of the support frame 11 to fix the position of the guide rail slider 22.

[0035] Working principle:

[0036] First, the base plate 12 is rotatably connected to the support frame 11 via bearings. When adjusting the installation position, rotate the bolts at the end of the base plate 12 to release the squeezing constraint on the base plate 12, so that the base plate 12 can deflect around the end of the support frame 11. After adjusting to the target position, tighten the screws to re-secure the base plate 12 and the support frame 11, and complete the overall installation and positioning of the bracket.

[0037] Place the heater duct body 13 on top of the support frame 11, and slide the two U-shaped clamps 14 symmetrically along the top of the support frame 11 until the rubber pads 15 on the inner side of the U-shaped clamps 14 are tightly attached to the outer side of the heater duct body 13. The rubber pads 15 are flexible buffer structures that can isolate the transmission of heater duct vibration to the support, achieving a shockproof effect. After the two U-shaped clamps 14 are attached to the heater duct, pull the retractable soft strap 16 that is rotatably installed at the top of one of the U-shaped clamps 14. The end of the rubber pad 15 rotates inside the U-shaped clamp 14 with the retractable soft strap 16; at the same time, the retractable soft strap 16 is pulled. The mounting plate 17 at the top of the flexible band 16 moves the buckle plate 18 toward another U-shaped clamp 14. Since the end of the buckle plate 18 is a protruding structure, it can be inserted into the other U-shaped clamp 14 to form a pre-tightening force. At the same time, the spring rod 19 inside the mounting plate 17 resets and generates a pushing force on the two sliding blocks 21, causing the sliding blocks 21 to slide along the inside of the mounting plate 17 and insert into the other U-shaped clamp 14, further locking the two U-shaped clamps 14 and quickly completing the fixation of the heating pipe body 13. When disassembling, the operation is reversed to unlock and achieve quick disassembly.

[0038] In the second step, a guide rail slider 22 is slidably installed inside the support frame 11. A connecting sleeve 26 is rotatably installed on the side end of the guide rail slider 22. A segmented partition plate 27 (with bolts on both sides) and multiple insert rods are fixed to the side end of the connecting sleeve 26. When adjusting the angle of the partition plate 27, the connecting sleeve 26 is pulled, causing it to slide within the limiting ring 25 (with multiple positioning holes on its surface) inside the guide rail slider 22. At the same time, the two reset push rods 24 connected to the end of the connecting sleeve 26 (the reset push rods 24 are installed on the side end of the rotating positioning ring 23 inside the guide rail slider 22) are stretched. The reset push rods 24 are stretched and contracted under force, causing the connecting sleeve 26 to slide outward and drive the insert rods to disengage from the positioning holes of the limiting ring 25. At this time, the connecting sleeve 26 is rotated, and one end of it carries... The movable partition plate 27 rotates to adjust its horizontal angle. Simultaneously, the connecting sleeve 26 drives the positioning ring 23 to rotate synchronously inside the guide rail slider 22 via two reset push rods 24. After the angle of the partition plate 27 is adjusted, the two reset push rods 24 apply a reverse pulling force to the connecting sleeve 26, causing the connecting sleeve 26 to slide inside the guide rail slider 22, driving the insertion rod to re-insert into the positioning hole of the limiting ring 25. Through the cooperation of the limiting ring 25 and the connecting sleeve 26, the angle of the connecting sleeve 26 and the partition plate 27 is locked, ensuring the stable position of the partition plate 27. The partition plate 27 has a segmented structure, which can be combined to fix different wire harnesses, so that the wire harnesses are arranged in an orderly manner along the installation direction of the support frame 11 and the base plate 12.

[0039] Two threaded rods 28 are rotatably mounted on the top of the guide rail slider 22, and a compression sleeve 29 is rotatably mounted on the surface of each threaded rod 28. A rotating rod is rotatably mounted on the side of the guide rail slider 22, and the end of the rotating rod is connected to the threaded rod 28 through a bevel gear. When fixing the position of the guide rail slider 22, rotating the rotating rod causes the threaded rod 28 to rotate clockwise inside the guide rail slider 22 through the bevel gear transmission, driving the compression sleeve 29 to slide along the top of the guide rail slider 22 until the compression sleeve 29 tightly presses the inner side of the support frame 11, thereby fixing the position of the guide rail slider 22 and ensuring the stability of the wire harness separation structure.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
