Power spring in the design of the car covers

source:Qianye Precision time:2022-9-14

Car covers are commonly used automotive protective articles, but the folding and storage of car covers is a troublesome thing. In order to solve this problem, invention lovers have done a lot of useful exploration and put forward many solutions.

One kind of scheme is to use power to drive the reel to directly roll up the car cover cloth. Using the reel to directly roll up the car cover cloth can achieve the purpose of rapid retraction of the car cover, but there are the following problems in actual use: first, the winding and friction of the reel when directly rolling up the car cover cloth wear the car cover cloth greatly; second, in order to adapt to the width of the car cover cloth, the width of the car cover retracting device must be close to the width of the car cover cloth. If it is too narrow, it will increase the winding of the car cover cloth, so the shape of the car cover retracting device is larger, It reduces the convenience of use: Third, it may not be able to completely stow the hood cloth.

Only one power spring is needed to solve the above series of problems. The power spring designed by Qianye precision can be applied to the car cover. The power spring retracts the car cover to realize the rapid retraction of the car cover. At the same time, it solves the problems of large wear, large device shape and high operation intensity caused by the direct retraction of the car cover cloth by the reel, as well as the problem that the car cover cloth cannot be completely retracted.

  The power spring retracting car cover with retracting cover rope is composed of car cover cloth (1), reel (19) and box (20) for storing car cover cloth (1), which is characterized in that: the surface of car cover cloth (1) is longitudinally fixed with a plurality of rope buckles (3), the rope buckles (3) are closed rings or rings closed with the surface of car cover cloth (1), one end of the retracting cover rope (2) is connected with the reel (19), and the other end passing through the rope buckles (3) is connected with the end of car cover cloth (1) away from the box (20), A power spring (12) mechanically interacting with the reel (19) is installed in the box (20).

  The shaft core of the power spring is fixedly connected with the non handle end of a crank. The crank has two functions, one is to fix the shaft core of the power spring, and two fixed bayonets are set on the outer wall of the box. When the crank is clamped on the bayonet, the shaft core of the power spring is fixed. The other function is to disengage the crank from the bayonet and rotate in the opposite direction of the winding direction of the power spring through the shaft core to store energy for the power spring, The stored energy can immediately drive the gears and reels to rotate, and all the car cover cloth will be put away.
