Description

Technical Field

[0001] This utility model belongs to the technical field of automotive door handles, specifically a return spring for automotive door handles. Background Technology

[0002] The modern automotive industry is undergoing rapid development with the advancement of science and technology. New processes, materials, and technologies are widely used, especially the collision and integration of electronic technology with traditional mechanics, propelling the automotive industry towards automation and intelligence. The combination of traditional car door handles and electronic technology has given rise to concealed door handles. Traditional straight-pull door handles protrude above the door panel, disrupting the vehicle's streamlined design and resulting in both aesthetics and increased wind resistance. However, existing concealed door handles suffer from complex structures and high costs. Furthermore, over time, when the outer door handle is damaged, the entire handle typically needs to be replaced, leading to significant resource waste and making replacement cumbersome, time-consuming, and labor-intensive.

[0003] Meanwhile, application number 201920165245.8 discloses an exterior door handle assembly with a buffer sleeve. This assembly includes an exterior door handle and a handle base. The handle base is mounted on the inner sheet metal of the door, and the exterior door handle is mounted on and rotatably connected to the handle base. Additionally, it includes a control lever linked to the exterior door handle, rotatably fixed to the handle base, and with a reset element between it and the handle base. The control lever has one or more buffer sleeves for buffering the reset collision between the control lever and the handle base, and the control lever also has a counterweight to increase its overall weight. Adding a buffer sleeve to the control lever linked to the exterior door handle prevents rigid impacts, while the counterweight increases the overall weight of the control lever, improving rebound noise and effectively enhancing the durability of the exterior door handle, thus improving vehicle quality.

[0004] However, the following problems were found in the implementation of the relevant technology: a car door handle assembly with a buffer sleeve was found to be unable to quickly reset during use, and the drag coefficient was increased and fuel consumption was increased during car operation.

[0005] Therefore, we propose a return spring for the exterior handle of a car door. Summary of the Invention

[0006] To address the problems mentioned in the background art, this utility model provides a car door handle return spring, which has the advantages of quickly opening the car door during use, retracting flush with the outer surface of the door, making the car door handle integrated with the overall vehicle design, making it more aesthetically pleasing, and reducing wind resistance and fuel consumption during vehicle operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a car door outer handle reset spring, comprising a car door body, a first groove being formed at the top of the car door body, a second groove being formed inside the first groove, a sliding post being reciprocated inside the second groove, a door outer handle body being fixedly provided at the top of the sliding post, a limiting block being fixedly provided on the inner wall of the sliding post, and a fixing post being fixedly provided at the bottom of the inner wall of the second groove.

[0008] Preferably, a third groove is provided inside the car door body, and a pressing plate is slidably provided inside the third groove.

[0009] Preferably, a sliding column is fixedly provided at the top of the extrusion plate, and a shock-absorbing plate is fixedly provided at the top of the sliding column, with the top of the shock-absorbing plate fitting against the bottom of the door handle body.

[0010] Preferably, a limiting groove is provided on the outer side of the fixed column, and a sliding plate is provided inside the limiting groove for reciprocating sliding, and the outer side of the sliding plate is in contact with the outer side of the limiting block.

[0011] Preferably, the fixed column has a reciprocating sliding reset column inside, and the sliding plate reciprocates inside the reset column.

[0012] Preferably, a first spring is fixedly provided at the top of the reset column, and the other end of the first spring is fixedly connected to the inner wall of the sliding column.

[0013] Preferably, a shaft base is rotatably provided at the top of the inner wall of the first groove, and a rotating plate is rotatably provided inside the shaft base, and the top of the rotating plate is fixedly connected to the bottom of the door handle body.

[0014] Preferably, a second spring is fixedly provided inside the third groove, and the top end of the second spring is in contact with the bottom end of the extrusion plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a reset post, allows the door handle body inside the first groove to be pulled when the car door body is opened. The rotation of the door handle body causes the rotating plate to rotate inside the shaft base. The rotation of the door handle body causes the sliding post to slide downward inside the second groove. The downward movement of the sliding post causes the limiting block to move downward. The downward movement of the limiting block causes the sliding plate to slide inside the limiting groove. The sliding plate causes the reset post to slide upward inside the fixed post. The first spring undergoes elastic deformation, stretching and contracting, thereby achieving the goal of quickly opening the car door during use. When retracted, it is flush with the outer surface of the car door, making the car door handle integrated with the overall vehicle design, which is more aesthetically pleasing. During car driving, it also reduces wind resistance and lowers fuel consumption.

[0017] 2. This utility model, by setting a shock-absorbing plate, allows the first spring to reset and rotate the door handle body after the door handle body is released. The outer side of the door handle body then comes into contact with the shock-absorbing plate. The movement of the shock-absorbing plate moves the sliding column, which in turn moves the pressing plate. The second spring inside the third groove undergoes elastic deformation, stretching and contracting, thereby achieving shock absorption and limiting of the door handle body, preventing damage to the door handle body during the reset process, and improving the service life of the door handle body.

[0025] Specifically, the interior of the car door body 1 is provided with a third groove 14, and a pressing plate 15 is slidably provided inside the third groove 14. The movement of the sliding column 17 drives the pressing plate 15 to move.

[0026] Furthermore, a sliding column 17 is fixedly provided at the top of the extrusion plate 15, and a shock-absorbing plate 18 is fixedly provided at the top of the sliding column 17. The top of the shock-absorbing plate 18 is attached to the bottom of the door handle body 3. The movement of the shock-absorbing plate 18 drives the sliding column 17 to move.

[0027] Furthermore, a limiting groove 8 is provided on the outer side of the fixed column 7, and a sliding plate 9 is provided inside the limiting groove 8 for reciprocating sliding. The outer side of the sliding plate 9 is in contact with the outer side of the limiting block 6. The limiting block 6 moves downward to drive the sliding plate 9 to slide inside the limiting groove 8.

[0028] It is worth noting that the fixed column 7 has a reciprocating sliding reset column 10 inside, and the sliding plate 9 reciprocates inside the reset column 10. The sliding plate 9 drives the reset column 10 to slide upward inside the fixed column 7.

[0029] It is worth noting that a first spring 11 is fixedly provided at the top of the reset column 10, and the other end of the first spring 11 is fixedly connected to the inner wall of the sliding column 5. The first spring 11 undergoes elastic deformation to stretch and contract.

[0030] It is worth mentioning that a shaft base 12 is rotatably provided at the top of the inner wall of the first groove 2, and a rotating plate 13 is rotatably provided inside the shaft base 12. The top of the rotating plate 13 is fixedly connected to the bottom of the door handle body 3. The rotation of the door handle body 3 drives the rotating plate 13 to rotate inside the shaft base 12.

[0031] It is worth emphasizing that a second spring 16 is fixedly installed inside the third groove 14, and the top end of the second spring 16 is in contact with the bottom end of the extrusion plate 15. The second spring 16 undergoes elastic deformation to stretch and contract.

[0032] The car door body 1 is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail here.

[0033] Working principle: When the car door body 1 is opened, the door handle body 3 inside the first groove 2 is pulled. The door handle body 3 rotates, causing the rotating plate 13 to rotate inside the shaft base 12. The rotation of the door handle body 3 causes the sliding column 5 to slide downward inside the second groove 4. The downward movement of the sliding column 5 causes the limiting block 6 to move downward. The downward movement of the limiting block 6 causes the sliding plate 9 to slide inside the limiting groove 8. The sliding plate 9 causes the reset column 10 to slide upward inside the fixed column 7. The first spring 11 undergoes elastic deformation, stretching and contracting, thereby achieving rapid opening of the car door during use. When retracting, it resonates with the door... The flush outer surface integrates the car door handle with the overall vehicle design, making it more aesthetically pleasing. During vehicle operation, it reduces wind resistance and fuel consumption. After the outer door handle body 3 is released, the first spring 11 resets, causing the outer door handle body 3 to rotate. The outer side of the outer door handle body 3 comes into contact with the shock absorber 18. The movement of the shock absorber 18 causes the sliding column 17 to move, which in turn causes the pressing plate 15 to move. The second spring 16 inside the third groove 14 undergoes elastic deformation, stretching and contracting, thereby achieving shock absorption and limiting of the outer door handle body 3, preventing damage to the outer door handle body 3 during reset, and improving the service life of the outer door handle body 3.
