Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an integrated damping rotation mechanism for automotive roof handles. Background Technology

[0002] With the continuous development of the automotive industry, consumers have placed higher demands on the comfort and safety of car interiors. As a commonly used auxiliary device for passengers during vehicle operation, the rationality of the structural design of car headliners directly affects user experience and safety. Traditional car headliners typically use a simple hinge structure, which is prone to generating abnormal noises due to vibrations during vehicle operation. Furthermore, long-term use can lead to increased clearance due to wear at the hinge points, affecting the handle's feel and lifespan.

[0003] To address the aforementioned issues, some automotive headliner handles with damping structures have emerged in the existing technology. For example, some solutions incorporate dampers at the rotating connection of the handle to provide a smooth operating feel and reduce noise. However, existing damping rotating structure designs still have some shortcomings. On the one hand, the connection between the damper and the fixed base often has significant fitting errors, leading to unstable damping effects; on the other hand, elastic elements such as torsion springs are directly exposed, which not only affects aesthetics but also makes them susceptible to environmental factors such as dust and moisture, reducing their service life. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an integrated damping rotation mechanism for automobile roof handles.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an integrated damping rotation mechanism for car roof handles, including a handle body, with mounting grooves at both ends of the handle body, and a fixed base rotatably connected to the mounting grooves. The fixed base includes a first fixed base and a second fixed base. The first fixed base is rotatably connected to the handle body via a first pin, and the first pin is provided with a damper. The damper includes a damping shell and a damping rotor. The damping shell is sleeved on the outside of the damping rotor. A left fixing block is provided on the left end face of the damping rotor, and a right fixing block is provided on the right end face of the damping rotor.

The two ends of the torsion spring abut against the mounting grooves and the second fixed base, respectively. A torsion spring protective sleeve is sleeved on the outside of the second pin, and the torsion spring is installed inside the torsion spring protective sleeve.

[0006] As a further improvement of this utility model: the inside of the torsion spring protective sleeve is provided with an annular cavity, one end of the annular cavity is open, and a guide groove is provided on the outer wall of the annular cavity along the axial direction.

[0008] As a further improvement of this utility model: the first fixed base and the second fixed base are respectively fixedly installed on the car roof bracket.

[0009] As a further improvement of this utility model: the first fixed base includes a first fixed seat and a first rotating part, and the first rotating part is rotatably connected to the handle body through a first pin.

[0010] As a further improvement of this utility model: the first fixing seat is provided with a left fixing groove and a right fixing groove, the left fixing groove matching the left fixing block and the right fixing groove matching the right fixing block. By providing left fixing grooves and right fixing grooves that match the left fixing block and the right fixing block respectively on the first fixing seat, the two ends of the damping rotor can be tightly fitted with the first fixing seat, reducing the fitting error between the two.

[0015] 2. This utility model uses a torsion spring protective sleeve to cover the outside of the second pin. The main body of the torsion spring is completely hidden in the annular cavity of the torsion spring protective sleeve, with only the beginning and end exposed. This integrated design not only eliminates the friction noise between the torsion spring and the second pin, but also avoids the torsion spring being directly exposed to the external environment, making the overall structure simpler and more beautiful.

[0022] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The invention will now be further described with reference to the accompanying drawings and embodiments:

[0023] Please see Figure 1-4 An integrated damping rotation mechanism for a car roof handle includes a handle body 1, with mounting grooves 2 at both ends of the handle body 1. The mounting grooves 2 are rotatably connected to a fixed base, which includes a first fixed base 3 and a second fixed base 4.

[0024] The first fixed base 3 is rotatably connected to the handle body 1 via the first pin 5. The first pin 5 is provided with a damper 6. The damper 6 includes a damping housing 7 and a damping rotor 8. The damping housing 7 is sleeved on the outside of the damping rotor 8. The left end face of the damping rotor 8 is provided with a left fixing block 9, and the right end face of the damping rotor 8 is provided with a right fixing block 10.

[0025] The second fixed base 4 is rotatably connected to the handle body 1 via the second pin 11. The second pin 11 is provided with a torsion spring. The two ends of the torsion spring abut against the mounting groove 2 and the second fixed base 4 respectively. A torsion spring protective sleeve 12 is sleeved on the outside of the second pin 11, and the torsion spring is installed inside the torsion spring protective sleeve 12.

[0026] The second pin 11 is equipped with a torsion spring, which can drive the handle body 1 to reset. The first pin 5 is equipped with a damper 6, which can slow down the reset speed of the handle body 1, thereby enhancing the comfort of use.

[0027] By providing a left fixed block 9 and a right fixed block 10 at both ends of the damping rotor 8, and setting fixed grooves on the first fixed base 3 that match the left fixed block 9 and the right fixed block 10 respectively, a rigid connection between the damping rotor 8 and the first fixed base 3 is achieved, so that both ends of the damping rotor 8 are tightly fitted with the first fixed base 3, reducing the fit error between the damping rotor 8 and the first fixed base 3, and ensuring the stability of the damping effect.

[0028] In some embodiments, the torsion spring protective sleeve 12 has an annular cavity 14 inside, one end of which is open. A guide groove 15 is formed on the outer wall of the annular cavity 14 along the axial direction. The starting end of the guide groove 15 is flush with the opening end of the annular cavity 14, and the end of the guide groove 15 is vertically connected to a positioning groove 16. The torsion spring is installed in the annular cavity 14. One end of the torsion spring extends from the opening end of the annular cavity 14 and abuts against the fixed base. The other end of the torsion spring extends from the positioning groove 16 and abuts against the mounting groove 2.

[0029] The torsion spring is covered by the torsion spring protective sleeve 12 on the outside of the second pin 11. The main body of the torsion spring is completely hidden in the annular cavity 14 of the torsion spring protective sleeve 12, with only the beginning and end exposed. This integrated design not only eliminates the friction noise between the torsion spring and the second pin 11, but also avoids the torsion spring being directly exposed to the external environment, making the overall structure simpler and more beautiful.

[0030] In some embodiments, the damping housing 7 and the damping rotor 8 are rotatably connected, and the damping rotor 8 is provided with a damping through hole 17, through which the first pin 5 passes.

[0031] In some embodiments, the first fixed base 3 and the second fixed base 4 are respectively fixedly installed on the car roof bracket (not shown in the figure).

[0032] In some embodiments, the first fixed base 3 includes a first fixed base 20 and a first rotating part 21, the first rotating part 21 being rotatably connected to the handle body 1 via a first pin 5.

[0033] In some embodiments, the first fixing seat 20 is provided with a left fixing groove 18 and a right fixing groove 19, wherein the left fixing groove 18 matches the left fixing block 9 and the right fixing groove 19 matches the right fixing block 10.

[0034] By setting left fixing groove 18 and right fixing groove 19 on the first fixing seat 20 respectively to match the left fixing block 9 and the right fixing block 10, the two ends of the damping rotor 8 can be tightly fitted with the first fixing seat 20, reducing the fitting error between the two.

[0035] In some embodiments, the left end face of the damping rotor 8 is provided with two left fixing blocks 9, the right end face of the damping rotor 8 is provided with two right fixing blocks 10, and the first fixing seat 20 is provided with two left fixing slots 18 and two right fixing slots 19.

[0036] In some embodiments, the second fixed base 4 includes a second fixed base 22 and a second rotating part 23. The two ends of the torsion spring abut against the mounting groove 2 and the second fixed base 22 respectively. The second rotating part 23 is rotatably connected to the handle body 1 through a second pin 11.

[0037] Furthermore, the hinged structure of traditional car roof handles is prone to loosening or even detachment after frequent use, posing a safety hazard. Therefore, in some embodiments, the left and right side walls of the mounting groove 2 are respectively provided with a left limiting groove 24 and a right limiting groove 25. The fixed base has a left rotating part 26 and a right rotating part 27. The end of the left rotating part 26 away from the right rotating part 27 has a left protrusion 28, and the end of the right rotating part 27 away from the left rotating part 26 has a right protrusion 29. The left protrusion 28 is inserted into the left limiting groove 24 and rotatably connected to it, and the right protrusion 29 is inserted into the right limiting groove 25 and rotatably connected to it.

[0038] The handle body 1 is provided with a left protrusion 28 and a right protrusion 29 by setting a fixed base. The left limiting groove 24 and the right limiting groove 25 are provided. The left protrusion 28 is inserted into the left limiting groove 24 and is rotatably connected to the left limiting groove 24. The right protrusion 29 is inserted into the right limiting groove 25 and is rotatably connected to the right limiting groove 25. This can realize the rotatable connection between the fixed base and the handle body 1, improve the stability of the connection between the handle body 1 and the fixed base, and effectively avoid the problem of the handle body 1 detaching from the fixed base during use.

[0039] The main functions of this utility model are:

[0040] This invention features a torsion spring on the second pin, which drives the handle body to reset. A damper is installed on the first pin to slow down the reset speed of the handle body, thus enhancing user comfort. Left and right fixing blocks are respectively located at both ends of the damping rotor, and fixing grooves matching these blocks are provided on the first fixed base, achieving a rigid connection between the damping rotor and the first fixed base. This ensures a tight fit between the two ends of the damping rotor and the first fixed base, reducing fitting errors and ensuring stable damping performance. A torsion spring protective sleeve covers the outside of the second pin, with the main body of the torsion spring completely concealed within the annular cavity of the sleeve, only the ends exposed. This integrated design not only eliminates frictional noise between the torsion spring and the second pin but also prevents the torsion spring from being directly exposed to the external environment, resulting in a simpler and more aesthetically pleasing overall structure.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
