Description

Technical Field

[0001] The utility model belongs to the technical field of automobile split central armrests, and in particular relates to a structure suitable for adjusting spring force of automobile split central armrests. Background Art

[0002] At present, many central armrests of the central control panel of automobiles are designed to open in a split form. The purpose is to improve the practicality of the armrest function. If the co-pilot puts his arm on the armrest, the driver can open the armrest close to the driver's side. Similarly, the armrest on the co-pilot side can also be opened separately. However, the split armrest has very high requirements for the synchronization of the opening of the left and right armrests. If the split armrests are not synchronized, one side will open particularly fast and the other side will open particularly slowly, affecting the aesthetics of the car interior. Poor synchronization will also cause low production qualification rate, cost waste and other problems. This patent designs a method to achieve synchronization of split armrests by adjusting the spring force value. Utility Model Content

[0003] The purpose of the utility model is to provide a structure suitable for adjusting the spring force of a split central armrest of a car, which solves the problem of asynchronous opening angles of the split armrests by adjusting the force value of the spring pushing the armrests by using four gear slots.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A structure for adjusting spring force of a split central armrest of an automobile, comprising: an upper cover plate 1, a support plate 2, a sliding bearing 3, a rotating shaft bracket 4, a spring 5, a damper rotating shaft 6, a damper 7, and a screw 8. The sliding bearing 3 is coaxially matched with the rotating shaft bracket 4 and can rotate around the axis of the rotating shaft bracket 4. The right end of the spring 5 (with Figure 3 As an example) is inserted into the hole A of the damper shaft 6 (such as Figure 4 As shown), the left end of the spring 5 is clamped in the second gear slot D of the upper cover plate 1, the damper shaft 6 is interference connected with the left end of the damper 7, and the right end of the damper 7 is clamped and connected with the upper cover plate 1; the shaft bracket 4 is coaxially matched with the damper shaft 6 and can rotate around the axis of the shaft bracket 4; the shaft bracket 4 is connected to the upper cover plate 1 by screws 8; the support plate 2 is connected to the upper cover plate 1 by welding; there are four gear slots, and the gear can be adjusted according to the required spring force; C is a first gear slot, D is a second gear slot, E is a third gear slot, and F is a fourth gear slot.

[0006] The sliding bearing 3 and the rotating shaft support 4 constitute the first sub-assembly; the spring 5, the damper rotating shaft 6 and the damper 7 constitute the second sub-assembly;

[0007] During assembly, first assemble the first sub-assembly and the second sub-assembly, then clamp the left end of the spring 5 into the second gear slot D of the upper cover 1, and then fix the first sub-assembly to the upper cover 1 with the screw 8. After assembly, turn the shaft bracket 4 to judge the time. If the time is slow, adjust the spring straight arm to the first gear of the upper cover 1. If the time is fast, adjust the spring straight arm to the third or fourth gear of the upper cover 1, and then weld it with the support plate 2. The principle is that the depth of the other side straight arm of the spring 5 of different gears inserted into the damper shaft 6 is different. The deeper the insertion depth, the greater the force value, and vice versa, the force value will become smaller, thereby changing the time when the armrest is opened.

[0008] The advantages and positive effects of the utility model are:

[0009] By adjusting the spring 5 at different positions on the upper cover plate 1 before welding to adjust the depth of the spring inserted into the damper shaft 6 to adjust the size of the spring force, the handrail can have good synchronization after welding and improve the qualified rate of the product. The purpose of the utility model is to provide a structure that can adjust the spring force value before welding, so that for the split handrail with the spring installed inside, the left and right handrails can be opened synchronously after assembly and welding.

The sliding bearing 3 is coaxially matched with the rotating shaft bracket 4 and can rotate around the axis of the rotating shaft bracket 4. The right end of the spring 5 (with Figure 3 As an example) is inserted into the hole A of the damper shaft 6 (such as Figure 4 As shown), the left end of the spring 5 is clamped in the second gear slot D of the upper cover plate 1, the damper shaft 6 is interference connected with the left end of the damper 7, and the right end of the damper 7 is clamped and connected with the upper cover plate 1; the shaft bracket 4 is coaxially matched with the damper shaft 6 and can rotate around the axis of the shaft bracket 4; the shaft bracket 4 is connected to the upper cover plate 1 by screws 8; the support plate 2 is connected to the upper cover plate 1 by welding; there are four gear slots, and the gear can be adjusted according to the required spring force; C is a first gear slot, D is a second gear slot, E is a third gear slot, and F is a fourth gear slot.
