TECHNICAL FIELD
[0001] The utility model relates to the field of automobile parts design, especially to a gear box damping support. BACKGROUND
[0002] The automobile central armrest box, as an important part of the automotive interior system, was originally designed to provide elbow support for passengers inside the vehicle, enhancing the comfort of the ride. However, with the rapid development of automotive technology, especially the widespread application of automation and intelligent technology, the function and form of the central armrest box are also evolving. Traditional central armrest boxes are usually fixed in position, but with the rise of intelligent cockpits, designers have begun to experiment with designing armrest boxes that are movable to accommodate the needs of different drivers and passengers. This design not only improves the convenience of use but also enhances the driving experience.
[0003] In the closed and soundproofed space of the car interior, any noise generated during the design of a movable central armrest box can affect the comfort and overall experience of driving.
[0004] Currently, during the design and production of the central armrest box, the gear box that cooperates with the lead screw in the control system produces noise during the fixing process. To increase the fixing effect, sheet metal parts are often used for fixing, and shims are added during fixing. However, due to the large deformation effect and small coverage area of the shims, after a period of use, there is still contact between the sheet metal parts and the upper rail, and this contact between metal materials is prone to friction noise. UTILITY MODEL CONTENTS
[0005] In view of the deficiencies in the prior art, the utility model provides a gear box damping support, which avoids metal-to-metal contact when the gear box is fixed on the upper rail by setting a damping support on the upper rail, solving the noise caused by metal friction.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A gear box damping support, comprising
[0008] a gear box;
[0009] a sheet metal part for fixing the gear box on the upper rail, and a damping support is arranged between the sheet metal part and the upper rail.
[0010] Preferably, the sheet metal part is used to fix the gear box, and the sheet metal part is bent to form a leg on the side edge of the gear box, and the damping support has a buckle on the leg.
[0011] Preferably, the surface of the damping support is unevenly constructed to fully contact the sheet metal part and the gear box.
[0012] Preferably, a lead screw is arranged to pass through the gear box, and a through hole is arranged on the sheet metal part for the lead screw to pass through.
[0013] Preferably, the lead screw is supported by a fixing frame arranged in the lower guide rail.
[0014] Preferably, a groove is arranged in the upper guide rail, and the damping support is fixed in the groove by the fixing member passing through the supporting leg.
[0015] Preferably, the clasp is arranged to be not less than two, and the clasp holds the sheet metal part and forms clamping.
[0016] Compared with the prior art, the utility model has the beneficial effects that:
[0017] The utility model provides a gear box damping support, which is arranged on the upper guide rail to avoid metal-to-metal contact when the gear box is fixed on the upper guide rail, and solves the noise caused by metal friction.
[0018] The damping support is made of plastic material to prevent noise and deformation, and the clasp is arranged on the damping support. The damping support fixes the gear box between the damping support and the sheet metal part by being connected with the sheet metal part, and the clasp holds the sheet metal part to form clamping effect, thereby avoiding the shift of the sheet metal part and the gear box.

EMBODIMENT
[0030] Please refer to Figures 1-5 The utility model provides a gear box damping support, including gear box 1, sheet metal part 2 and damping support 3, sheet metal part 2 is used for fixing gear box 1 on the upper guide rail, and damping support 3 is arranged between sheet metal part 2 and the upper guide rail to reduce noise.
[0031] It should be noted that the upper guide rail of the utility model is arranged on the sliding platform, and the fixed platform is below the upper guide rail. The fixed platform has a lower guide rail corresponding to the upper guide rail. The sliding platform and the fixed platform are used for the automobile central armrest box, and are made into a mobile middle grade to adapt to the adjustment and use of automatic and intelligent automobiles.
[0032] The upper guide rail is in sliding fit with the lower guide rail, the screw rod 4 passes through the sheet metal part 2 and the gear box 1, the screw rod 4 is in transmission fit with the gear box 1, the motor output shaft penetrates into the gear box 1, the transmission of the screw rod 4 is controlled through the gear box 1, and the two ends of the screw rod 4 are provided with the fixing frame 5 which is fixed to the lower guide rail. The rotation of the screw rod 4 is controlled under the driving of the motor, and the upper guide rail moves along the lower guide rail.
[0033] Further, the sheet metal part 2 is arranged outside the gear box 1 to increase the fixing effect, and a through hole 22 larger than the diameter of the screw rod 4 is formed in the sheet metal part 2 to avoid contact with the screw rod 4. The gear box 1 is provided with a damping layer on the surface to reduce the contact noise between the sheet metal part 2 and the gear box 1.
[0034] The end of the sheet metal part 2 is bent to form the supporting leg 21 which can directly contact the upper guide rail, and the supporting leg 21 and the upper guide rail are fixed through the fixing part 6, that is, the gear box 1 is fixed on the upper guide rail. Further, since the sheet metal part 2 and the upper guide rail are both metal materials, the wear and friction noise are easily increased; at present, a gasket is added between the sheet metal part 2 and the upper guide rail, but the deformation effect of the gasket is large and the covering area is small. After being used for a period of time, the sheet metal part 2 still contacts the upper guide rail.
[0035] The damping support 3 is made of plastic material, one side of the damping support 3 is provided with unevenness and the two ends are integrally formed with buckles 31. In use, the gear box 1 is placed in the middle of the damping support 3, and then the sheet metal part 2 is covered on the gear box 1, and the two supporting legs 21 of the sheet metal part 2 are both in the damping support 3 and are clamped by the buckles 31. The unevenness on the surface of the damping support 3 is to make the gear box 1 and the sheet metal part 2 fully contact the damping support 3 when being installed in the above manner. The buckles 31 clamp the two ends of the sheet metal part 2 and form clamping at the same time, so that the relative movement of the gear box 1 and the sheet metal part 2 on the damping support 3 is avoided.
[0036] In addition, the upper guide rail is internally formed with a groove 7, the damping support 3 is located in the groove 7, and the fixing part 6 is connected and fixed with the upper guide rail at the groove 7 after penetrating through the supporting leg 21 and the damping support 3.
[0037] In addition, a gasket can be further added on the two sides of the damping support 3 to achieve long-term stable effect.
[0038] Those skilled in the art should understand that the embodiments of the utility model shown in the above description and the drawings are only taken as examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been shown and explained in the embodiments, and the implementation of the utility model can be any deformation or modification without departing from the principle.
