The top of metal guide ring and screw rod adopts squeeze riveter fixed connection, and the flocking is adhered to the metal guide ring outside, and screw rod and the inside threaded connection of direction nut, flocking and the laminating of direction nut inner wall slip. The guide ring is designed by adopting a metal material, has high hardness and high tensile strength, is not easy to stretch, deform and damage, improves the durability of the guide ring running in the guide nut, and avoids the risk of abnormal sound and shaking caused by the deformation of the guide ring; the guide ring is produced and fixed by adopting a squeeze riveting process, a photographing system is not needed for error prevention, the production beat can be reduced, the automation of a production line is convenient, parts are saved, and the production cost is reduced; the flocking design on the outer surface of the guide ring can realize strong oily adhesion force of the suede, is not easy to generate abnormal sound when contacting with the inner wall of the guide nut, enhances the guide performance and avoids the abnormal sound when the guide ring runs in the guide nut combination.
Description
Technical Field
The utility model belongs to an electric stay bar structure of an automobile back door.
Background
The electric supporting rod for the automobile back door not only can effectively enable the automobile back door to be stably opened or closed, but also is reasonable in structure, low in use cost, stable in quality and long in service life, the working principle of the electric supporting rod is that the electric supporting rod is optimally designed through kinematic mechanical calculation, and the optimal solution is realized through adjusting variables such as torque of a motor, speed ratio of a gear box, lead of a lead screw, spring force value and the like. The ECU controls the double electric supporting rods to realize smooth movement and double rod synchronization.
The guide ring 1 in the current structure is assembled and needs two gaskets 5 and 6 to fix the guide ring internally and externally, as shown in fig. 4, the assembly steps are more, the working time is longer, the automatic production is inconvenient, the production cost is higher, the guide ring is easy to damage due to the parts, the shaking amount is large, and abnormal sound is easy to occur. The original guide ring 1 is drum-shaped and made of rubber, and as shown in fig. 5, the tensile strength is low, the deformation is easy to damage, and the durability is poor. The surface of the original guide ring is not beneficial to the adhesion of grease, abnormal sound appears in the running process, and the use experience of a user is affected.
Disclosure of Invention
The utility model provides an electric stay bar structure of a back door, which is stable in operation, and aims to solve the problems that a guide ring is easy to damage, more in assembly steps, low in tensile strength, poor in durability and abnormal sound in the operation process.
The technical scheme includes that the metal guide ring, the guide nut, the screw and the flocking are included, wherein the metal guide ring is fixedly connected with the top end of the screw through press riveting, the flocking is adhered to the outer portion of the metal guide ring, the screw is in threaded connection with the inner portion of the guide nut, and the flocking is in sliding fit with the inner wall of the guide nut.
The metal guide ring is cylindrical.
The guide ring is designed by adopting a metal material, has high hardness and high tensile strength, is not easy to stretch, deform and damage, improves the durability of the guide ring running in the guide nut, and avoids the risk of abnormal sound and shaking caused by deformation of the guide ring; the guide ring is produced and fixed by adopting a squeeze riveting process, a photographing system is not needed for error prevention, the production beat can be reduced, the automation of a production line is convenient, parts are saved, and the production cost is reduced; the flocking design on the outer surface of the guide ring can realize strong oily adhesion force of the suede, is not easy to generate abnormal sound when contacting with the inner wall of the guide nut, enhances the guide performance and avoids the abnormal sound when the guide ring runs in the guide nut combination.

Detailed Description
The metal guide ring comprises a metal guide ring 1, a guide nut 2, a screw rod 3 and flocking 4, wherein the top ends of the metal guide ring 1 and the screw rod 3 are fixedly connected by adopting squeeze riveting, the flocking 4 is bonded outside the metal guide ring 1, the screw rod 3 is in threaded connection with the inside of the guide nut 2, and the flocking 4 is in sliding fit with the inner wall of the guide nut 2.
The metal guide ring 1 is cylindrical.
Working principle:
The motor drives the screw rod and the guide ring to carry out telescopic motion in the guide nut through the gear motion of the drive gear box, so that the functions of opening and closing the support rod are achieved, the operation strength and the service life of the screw rod and the guide nut are enhanced, the abnormal sound risk is reduced, the guide ring is further optimized, the guide ring 1 is made of metal materials, the rubber materials of the guide ring are different from those of the original guide ring, the tensile strength is high, the deformation is not easy to damage, and the durability and the service life of a product are enhanced. The metal guide ring 1 adopts a production process design of riveting fixation, so that the production and assembly are convenient, the guide ring is fixed inside and outside the two gaskets 5 and 6 required by the original guide ring assembly, the original guide ring assembly steps have long multiplexing time, the automatic production is inconvenient, and the production cost is high; the metal guide ring 1 adopts the design that cylinder, surface flocking 4 realize guide ring and direction nut 2 inner wall laminating degree, and the flocking surface is favorable to the adhesive force of grease, avoids appearing risks such as abnormal sound in the operation in-process.
