Description

Technical Field

[0001] The utility model belongs to the technical field of clock springs, and in particular relates to a clock spring with a steering wheel heating function. Background Art

[0002] As a key component, the clock spring cleverly connects the main airbag and the complex airbag wiring harness system, ensuring that the wiring harness can maintain the necessary slack during the flexible rotation of the steering wheel. Even when the steering wheel is rotated to an extreme position, the cable can be prevented from being damaged due to excessive tension, thus ensuring driving safety.

[0003] For some models that are not equipped with steering wheel heating, the clock springs they use are often designed with a lower current carrying capacity to match basic electrical needs. However, with the upgrade of automobile configuration, especially the introduction of steering wheel heating for a more comfortable driving experience, higher requirements are placed on the current carrying capacity of the clock spring. Therefore, these models need to be replaced with clock springs designed for high-power current to meet the power transmission requirements of the newly added functions (such as: steering wheel heating function).

[0004] It is worth noting that while traditional high-power clock springs solve the problem of high current transmission, they also face significant challenges: the huge heat generated when high current passes through, which not only accelerates the aging process of the flexible cable and shortens its service life, but also may cause short circuit risks in extreme cases, endangering driving safety.

[0005] Therefore, it is very necessary to invent a clock spring with a steering wheel heating function. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a clock spring with a steering wheel heating function, comprising a plug-in bottom shell, a heat dissipation top cover, side ears and a plug-in port, the heat dissipation top cover is rotatably mounted on the plug-in bottom shell, the side ears and the plug-in port are fixedly mounted on the plug-in bottom shell, and a second plug-in port is provided on the heat dissipation top cover;

[0007] The heat dissipation top cover includes a top cover body, a card slot, a dust blocking cover, a buckle slot, a heat dissipation dust blocking hole, a heat dissipation hole and a disturbance plate. The top cover body is rotatably mounted on the plug-in bottom shell; the dust blocking cover is embedded in the card slot arranged on the top cover body, and the buckle slot and the heat dissipation dust blocking hole are provided on the dust blocking cover; the heat dissipation hole is provided at the bottom of the card slot; the disturbance plate is fixedly mounted on the inner side of the top cover body.

[0008] Preferably, the card slot provided on the outside of the top cover body is an annular slot, the card slot is arranged on one side of the second plug interface fixedly mounted on the top cover body, and the card slot and the dust cover are provided with corresponding card embedding structures.

[0009] Preferably, there is a spacing for gas flow between the dust-proof cover and the bottom of the card slot. An arc-shaped buckling groove is provided on the outer surface of either end of the dust-proof cover, and the heat dissipation and dust-proof holes formed in the dust-proof cover are "Z"-shaped slot holes with two corners.

[0010] Preferably, the hot air inside the plug-in bottom shell and the top cover body sequentially flows through the heat dissipation holes and the heat dissipation and dust-proof holes and is discharged outside. The center of the top cover body is fixedly connected to the steering wheel shaft through a driver.

[0011] Preferably, a plurality of the disturbing plates are evenly and fixedly installed inside the top cover body. The disturbing plates are located below the heat dissipation holes, and the disturbing plates have inclined surfaces capable of promoting gas flow.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The heat dissipation top cover innovatively introduced by the utility model not only builds a solid barrier to effectively resist the intrusion of external dust, but also cleverly uses the elaborate layout of the heat dissipation and dust-proof holes and the heat dissipation holes to build a smooth air circulation network, greatly enhancing the overall heat dissipation efficiency.

[0014] Particularly worth mentioning is that the design of the heat dissipation and dust-proof holes is ingenious, adopting a unique "Z"-shaped path. This innovation not only significantly extends the trajectory of the hot air during the flow process, making the heat exchange process more sufficient and doubling the efficiency; at the same time, its clever corner design is like a natural filter, effectively preventing the direct intrusion of dust, ensuring the cleanliness and stable operation of the internal components, and realizing the dual optimization of heat dissipation and dust prevention.

[0015] In addition, when the steering wheel rotates flexibly with the operation of the driver, this dynamic process is given a new function - driving the heat dissipation top cover to rotate synchronously. The disturbing plates carefully designed on the heat dissipation top cover actively interact with the flowing gas during the rotation process, and further promote the air flow and mixing by increasing the turbulence, thereby realizing another leap in the heat dissipation efficiency and ensuring the stability and safety of the high-power current clock spring under high-load operation.

[0023] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0024] A clock spring with a steering wheel heating function provided by the present utility model includes a plug-in bottom shell 1, a heat dissipation top cover 2, a side ear 3, and a plug-in interface 4. The heat dissipation top cover 2 is rotatably installed on the plug-in bottom shell 1. The side ear 3 and the plug-in interface 4 are fixedly installed on the plug-in bottom shell 1. A second plug-in interface 4 is provided on the heat dissipation top cover 2.

[0025] The heat dissipation top cover 2 includes a top cover main body 21, a card slot 22, a dust-proof cover 23, a buckle slot 24, heat dissipation and dust-proof holes 25, heat dissipation holes 26 and a disturbance plate 27. The top cover main body 21 is rotatably installed on the plug-in bottom case 1. The dust-proof cover 23 is clamped in the card slot 22 provided on the top cover main body 21. The buckle slot 24 and the heat dissipation and dust-proof holes 25 are provided on the dust-proof cover 23. The heat dissipation holes 26 are provided at the bottom of the card slot 22. The disturbance plate 27 is fixedly installed inside the top cover main body 21. The heat dissipation top cover 2 not only constructs a solid barrier to effectively resist the intrusion of external dust, but also can build a smooth air circulation network, greatly enhancing the overall heat dissipation efficiency.

[0026] Embodiment 1:

[0027] Specifically, the top cover main body 21, as the basis of the entire heat dissipation structure, is externally designed with a card slot 22 in the form of an annular groove. The card slot 22 is carefully arranged on the top cover main body 21, adjacent to the second plug-in interface 4 fixedly installed on one side, aiming to form a stable and flexible connection with the dust-proof cover 23. Through the corresponding clamping structure design of the card slot 22 and the dust-proof cover 23, a connection method that is both tight and easy to maintain is achieved. This design not only ensures that the dust-proof cover 23 can firmly cover the top cover main body 21, but also facilitates disassembly and cleaning when necessary.

[0028] Specifically, the deliberately reserved gas flow spacing between the dust-proof cover 23 and the card slot 22 provides the necessary conditions for the smooth discharge of hot air. This design ensures that hot air is not blocked during the heat dissipation process, thereby improving the heat dissipation efficiency. An arc-shaped buckle slot 24 is designed on the outer surface of one end of the dust-proof cover 23. This detailed design may be used for positioning and fixing during the installation or disassembly process, enhancing the practicality of the structure. The heat dissipation and dust-proof holes 25 provided on the dust-proof cover 23 adopt a unique "Z"-shaped slot design. The layout of the two corners not only extends the flow path of hot air, improves the heat exchange efficiency, but also effectively prevents the entry of dust through the blocking effect of the corners, realizing the dual functions of heat dissipation and dust prevention.

[0029] Specifically, the hot air inside the plug-in bottom case 1 and the top cover main body 21 will flow along a specific path after the temperature rises, and is discharged to the external environment through the heat dissipation holes 26 and the heat dissipation and dust-proof holes 25 in sequence. This process ensures that hot air can be quickly and effectively evacuated, thereby maintaining the appropriate working temperature of the internal components.

[0030] Specifically, the center of the top cover body 21 is fixedly connected to the steering wheel shaft through a driver. This design enables the top cover to move synchronously with the rotation of the steering wheel. A number of disturbing plates 27 are evenly distributed and fixedly installed inside the top cover body 21. These disturbing plates 27 are located below the heat dissipation holes 26, and their shape is designed with inclined surfaces that can promote gas flow. When the top cover body 21 rotates with the steering wheel, the disturbing plates 27 will actively disturb the flowing gas, increasing the turbulence effect and further improving the heat dissipation efficiency and air fluidity.

[0031] Embodiment 2:

[0032] Heat dissipation mechanism:

[0033] Hot air circulation path: When the clock spring generates heat during operation, the hot air inside the plug-in bottom shell 1 and the inner side of the top cover body 21 will expand due to heat and rise. This hot air first enters the internal space of the heat dissipation top cover 2 through the heat dissipation holes 26 opened on the top cover body 21.

[0034] "Z"-shaped heat dissipation and dust-proof holes 25: Subsequently, the hot air flows through the "Z"-shaped heat dissipation and dust-proof holes 25 opened on the dust-proof cover 23. This unique design not only extends the flow path of the hot air, increases the time and area of heat exchange, and improves the heat dissipation efficiency; at the same time, its corner design also plays a role in blocking dust from entering, keeping the internal components clean.

[0035] Gas disturbance enhances heat dissipation: The disturbing plates 27 installed inside the top cover body 21, driven by the rotation of the steering wheel, will actively disturb the flowing gas, generating a turbulence effect. This turbulence not only further promotes the mixing and convection of the hot air, but also accelerates the heat exchange process and improves the overall heat dissipation effect.

[0036] Dust-proof mechanism:

[0037] Snap-fit structure for sealing: The snap-fit structure design corresponding to each other between the card slot 22 and the dust-proof cover 23 forms a tight and stable connection. This design effectively prevents external dust from entering the inside of the heat dissipation top cover 2 through the gap, ensuring the cleanliness of the internal components.

[0038] "Z"-shaped slot hole dust-proof: The "Z"-shaped design of the heat dissipation and dust-proof holes 25, while increasing the flow path of the hot air, also blocks the direct entry of dust through its corner structure. This design not only ensures the heat dissipation effect but also takes into account the dust-proof requirements.

[0039] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
