Description
Technical Field
The invention belongs to the technical field of automobile electrical assemblies, and particularly relates to a clock spring for an automobile.
Background
At present, because an airbag and a steering wheel switch are commonly installed on an automobile steering wheel, a clock spring is widely adopted in order to meet the requirements of connecting a wiring harness of the airbag and the switch with a wiring harness of a vehicle body.
The clock spring is internally provided with a flat cable, when the stress is overlarge, welding spots can be broken, the clockwise rotation circle number and the anticlockwise rotation circle number of the clock spring of the conventional passenger car are respectively more than or equal to 2 circles, the clockwise rotation circle number and the anticlockwise rotation circle number of the clock spring of the commercial car are respectively more than or equal to 3 circles, and the maximum rotation circle number of the steering gear is respectively larger than the maximum rotation circle number of the steering gear. However, when the vehicle is serviced and the clock spring or the steering wheel needs to be detached, if the clock spring is not in the centering position when being installed again, the clock spring is rotated clockwise or anticlockwise for a plurality of turns, and when the steering wheel is driven in the limiting position, the rotation number of the clock spring exceeds the maximum design value, and the torque acting on the steering wheel breaks the cable inside the clock spring.
Disclosure of Invention
In view of the above problems, the present invention aims to provide a clock spring for an automobile, which ensures that the clock spring can be assembled only at a correct position, and avoids the wire harness breakage phenomenon that the clock spring is not returned to the centering position after being disassembled.
The technical scheme of the invention is realized as follows:
The clock spring for the automobile is characterized in that an auxiliary stator is added on a clock spring stator, and comprises a shifting block, a driven gear, a gear mechanism, a positioning block and a limiting mechanism; the poking block is arranged on the upper cover of the clock spring, the position of the poking block and the position of the driven gear form an angle of 180 degrees by taking the center of the clock spring as an origin, and the driven gear can rotate for a certain angle under poking of the poking block; the driven gear shaft is rotationally connected with the gear mechanism and positioned through a gear pin, the positioning block is fixedly connected with the bottom of the gear shaft of the driven gear, the limiting mechanism is positioned below the positioning block, the upper surface of the limiting block is provided with a limiting hole consistent with the projection shape of the positioning block, and the limiting mechanism is of a hollow structure.
Further, the driven gear is shifted to rotate 60 degrees for each rotation of the shifting block.
Further, the gear mechanism is internally provided with a spring and a track, and the driven gear shaft compresses the gear pin to move in the track through the spring, so that the driven gear can be fixed in position when rotating to each gear, and multi-gear stop motion is realized.
The invention can ensure that the clock spring can be assembled only at the correct position, and avoid the wire harness fracture phenomenon caused by the fact that the clock spring does not return to the centering position after being disassembled.

Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an automobile clock spring is provided, wherein an auxiliary stator and a rotor connected with the auxiliary stator are added on a clock spring stator, and the auxiliary stator comprises a shifting block 1, a driven gear 2, a gear mechanism 3, a positioning block 4 and a limiting mechanism 5. The driving block 1 is arranged on the upper cover of the clock spring, the steering wheel rotates to drive the upper cover of the clock spring to rotate, the driving gear 2 can be meshed with the driving block 1, the driving gear 2 is rotated for 60 degrees when the driving block 1 rotates for one circle, the section view of the gear mechanism 3 is shown in fig. 2, the spring 6, the gear pin 7 and the track 8 are arranged in the gear mechanism 3, the gear shaft of the driven gear 2 compresses the gear pin 7 to move in the track 8 through the spring 6, and the driven gear 2 can be fixed in position when rotating to each gear, so that multi-gear stop-motion is realized. The positioning block 4 is fixedly connected with the bottom of the gear shaft of the driven gear 2, and the positioning blocks 4 are respectively at different angles when the driven gear 2 rotates at each gear. The limiting mechanism 5 is provided with a limiting hole with the same projection shape as the positioning block on the projection surface of the positioning block 4, and the inside of the limiting hole is hollowed out, so that the positioning block can normally rotate after falling into the through hole, and the limiting mechanism 5 is arranged on a bracket outside the clock spring and positioned below the positioning block 4. The shifting block is arranged on one side of the clock spring cover, which is far away from the driven gear, so that the position of the shifting block and the position of the driven gear form an angle of 180 degrees by taking the center of the clock spring as an original point, and the purpose is to ensure that the clock spring can not drive the driven gear within a rotation range of +/-180 degrees, thereby improving the durability of the whole mechanism.
The working principle of the invention is as follows: when the clock spring is in the middle position, the relative positions of the driven gear and the positioning block are fixed, at the moment, the positioning block can pass through a limiting Kong Lajin limiting mechanism on the projection surface of the limiting mechanism, when Zhong Danhuang rotates clockwise or anticlockwise more than 1 circle, the positioning block rotates along with the driven gear, the positioning block is fixed at a corresponding angle, the pulling out or the installation cannot be carried out, and fig. 3 is a schematic diagram of the position of the positioning block when the clock spring rotates anticlockwise for 1 circle and 2 circles, and the positioning block cannot pass through a limiting hole on the limiting mechanism at the moment. Zhong Danhuang can be installed and disassembled only when the clock spring is in the correct position, so that the clock spring is prevented from being in the centering position, but is rotated clockwise or anticlockwise for a plurality of turns, and when the steering wheel is in the limiting position, the torque acting on the steering wheel breaks the cable in the clock spring.
