Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clock springs, and particularly relates to a side plug-in clock spring. Background Art
[0002] A clock spring, also known as a rotary connector, airbag clock spring or spiral cable, its core function is to seamlessly connect the main airbag and the airbag wiring harness, as well as the complex wiring harness network between various switch buttons on the steering wheel and the control unit. This delicate design ensures that even when the steering wheel rotates in all directions, the electrical connection can remain stable and uninterrupted, safeguarding driving safety.
[0003] Before installing the clock spring, it is crucial to precisely zero the number of its rotation turns. This is because the clock spring needs to closely follow every subtle rotation of the steering wheel to ensure the continuity and reliability of electrical signal transmission. To achieve this goal, precise calibration between the clock spring and the steering wheel must be carried out to prevent the wiring harness from being damaged or broken due to excessive stretching when the steering wheel turns to the extreme position.
[0004] However, traditional calibration methods often rely on rough manual estimation or unclear markings, and are completed by repeatedly trying to rotate forward and backward a specific number of turns according to a fixed calibration method. This process is not only time-consuming and laborious, but also extremely likely to result in inaccurate calibration results due to human errors. More troublesome is that there is often a lack of an immediate and intuitive feedback mechanism during the calibration process, making it difficult for the operator to accurately judge whether the calibration has reached the optimal state, further increasing the operation difficulty and uncertainty.
[0005] Therefore, it is very necessary to invent a side plug-in clock spring. Content of the Utility Model
[0006] To solve the above technical problems, the utility model provides a side plug-in clock spring, which includes a base, mounting ears, a correction feedback device, a sliding cover, a protection track and gear teeth. Four mounting ears and two mirror-image correction feedback devices are fixedly installed on the base. The sliding cover is slidably installed on the base, and the protection track is fixedly installed on the two correction feedback devices; the gear teeth are fixedly installed on the outside of the sliding cover.
[0007] The correction feedback device includes a housing, an observation window, a correction gear, a limit spring piece and a correction mark. The housing is fixedly installed on the base and fixedly connected to the protection track. The observation window is arranged on the outer surface of the housing; the correction gear is rotatably installed inside the housing, and the limit spring piece is fixedly installed. The limit spring piece engages with the correction gear; several correction marks are arranged on the outer surface of the correction gear.
[0008] Preferably, the outer shell and the protection track are interconnected and neither is connected to the outer surface of the sliding cover. The gear teeth fixedly installed outside the sliding cover are located inside the protection track. The cavity provided in the protection track allows the gear teeth to slide along a circular trajectory inside itself, allows meshing with the correction gear, and can drive the correction gear to perform a small-range rotational movement.
[0009] Preferably, there is always a correction mark directly below the observation window. The correction mark is an Arabic numeral, and the correction mark inside the outer shell can be observed through the observation window.
[0010] Preferably, the limiting spring piece is a pick made of spring steel. After being squeezed by the correction gear, the limiting spring piece will deform, and the deformed limiting spring piece will limit the correction gear.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model introduces a correction feedback device, realizing precise adjustment and instant feedback of the position of the sliding cover. The correction gear inside the correction feedback device is tightly meshed with the gear teeth outside the sliding cover. As the sliding cover moves, the gear teeth slide along the cavity inside the protection track, precisely driving the correction gear to rotate, so that users can carefully record the number of turns the sliding cover rotates. At the same time, the ingenious setting of the observation window allows users to directly observe the internal correction mark (Arabic numeral), and they can intuitively understand the current state of the sliding cover without any complex operation, greatly improving the user experience. In addition, the design is also equipped with a limiting spring piece made of spring steel, and its excellent elasticity and durability ensure that the sliding cover can stay firmly after reaching the set position, effectively preventing accidental movement caused by inertia or external force. The overall structure is compact and efficient, and the components cooperate closely. It not only realizes powerful functions but also optimizes space utilization, demonstrating the ingenuity and practicality of the design. Description of the Drawings

[0020] As shown in the attached Figure 1 to the attached Figure 3 figures:
[0021] A side plug-in clock spring provided by the present utility model includes a base 1, mounting ears 2, a correction feedback device 3, a sliding cover 4, a protection track 5, and gear teeth 6. Four of the mounting ears 2 are fixedly installed on the base 1, and two of the correction feedback devices 3 are arranged symmetrically. The sliding cover 4 is slidably installed on the base 1, and the protection track 5 is fixedly installed on the two correction feedback devices 3; the gear teeth 6 are fixedly installed outside the sliding cover 4, and the specific position and number of the gear teeth 6 are determined according to requirements and models.
[0022] The correction feedback device 3 includes a housing 31, an observation window 32, a correction gear 33, a limit spring piece 34, and a correction mark 35. The housing 31 is fixedly installed on the base 1 and is fixedly connected to the protection track 5. The observation window 32 is arranged on the outer surface of the housing 31. The correction gear 33 is rotatably installed inside the housing 31, and the limit spring piece 34 is fixedly installed. The limit spring piece 34 is engaged with the correction gear 33. A plurality of the correction marks 35 are arranged on the outer surface of the correction gear 33. The correction feedback device 3 realizes precise adjustment and instant feedback of the position of the sliding cover 4. The correction feedback device 3 can be closely engaged with the teeth 6 outside the sliding cover 4, so that the user can carefully record the number of turns that the sliding cover 4 rotates.
[0023] Embodiment 1:
[0024] Specifically, the housing 31 and the protection track 5 are ingeniously designed to be a mutually connected structure. This design not only ensures the structural compactness but also allows the teeth 6 outside the sliding cover 4 to freely slide along a circular track in the cavity inside the protection track 5. This sliding mechanism is the core of adjusting the position of the sliding cover 4. It ensures that the teeth 6 can be effectively engaged with the correction gear 33 inside the correction feedback device, and then drives the correction gear 33 to perform a small-range rotational movement through the rotation of the teeth 6, so that the user can carefully record the number of turns that the sliding cover 4 rotates.
[0025] Specifically, in order to provide intuitive adjustment feedback, the observation window 32 is arranged on the housing 31. This design enables the user to directly observe the internal correction marks 35 through the observation window 32 without opening the housing 31 or performing other complex operations. In particular, the correction marks 35 adopt easily recognizable Arabic numerals, ensuring that a clear number will be displayed directly below the observation window 32 in any adjustment state, accurately reflecting the number of turns that the sliding cover 4 rotates currently.
[0026] Specifically, in order to ensure that the sliding cover 4 can stay stably after rotating a specific number of turns, this embodiment also introduces the limit spring piece 34 as a key limiting mechanism. The limit spring piece 34 is made of spring steel material and has good elasticity and durability. When the correction gear 33 rotates under the extrusion of the teeth 6, the limit spring piece 34 will deform accordingly. Once the correction gear 33 rotates to the preset limit position, the deformed limit spring piece 34 will play its limiting role and effectively prevent the further rotation of the correction gear 33, thereby ensuring that the sliding cover 4 can stay stably at the predetermined position and preventing accidental movement caused by inertia or external force.
[0027] Embodiment 2:
[0028] Precision meshing mechanism: The gear teeth 6 outside the sliding cover 4 are closely meshed with the correction gear 33 inside the correction feedback device 3. When the sliding cover 4 slides along the protection track 5, the gear teeth 6 will rotate accordingly. For each full rotation of the sliding cover 4, it further drives the correction gear 33 to perform a small-range rotational movement. This meshing mechanism ensures the precise adjustment of the position of the sliding cover 4.
[0029] Instant feedback system: The observation window 32 provided on the outer shell 31 of the correction feedback device 3 provides intuitive feedback to the user. The correction mark 35 (Arabic numerals) directly below the observation window 32 will change as the correction gear 33 rotates, accurately reflecting the number of rotations of the current sliding cover 4. Users can obtain the required information through the observation window 32 without complex operations.
[0030] Stable limiting mechanism: The limiting spring piece 34 serves as a key limiting mechanism to ensure that the sliding cover 4 can stay stably after reaching a specific number of rotations. When the correction gear 33 rotates to the preset limit position, the limiting spring piece 34 will deform and limit the further rotation of the correction gear 33, thereby preventing the sliding cover 4 from accidentally moving due to inertia or external forces.
[0031] Workflow:
[0032] Initial state: After the clock spring is installed, the sliding cover 4 is in the initial position, and the correction gear 33 and the gear teeth 6 are in the initial meshing state. The correction mark 35 directly below the observation window 32 shows the initial number of rotations.
[0033] Adjustment process: The user adjusts the position of the sliding cover 4 as needed. As the sliding cover 4 slides, the gear teeth 6 drive the correction gear 33 to rotate, and at the same time, the correction mark 35 in the observation window 32 also changes accordingly. The user can understand the number of rotations of the sliding cover 4 in real time through the observation window.
[0034] Limiting and stabilization: When the sliding cover 4 reaches the predetermined position, the correction gear 33 rotates to the preset limit position. At this time, the limiting spring piece 34 deforms and limits the further rotation of the correction gear 33, ensuring that the sliding cover 4 can stay stably at the predetermined position.
[0035] Feedback confirmation: The user confirms through the observation window 32 that the sliding cover 4 has stayed stably at the predetermined position and checks whether the number of rotations shown by the correction mark 35 meets the requirements.
[0036] Using the technical solution described in the present utility model, or a person skilled in the art designing a similar technical solution inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
