Technical Field

[0001] The utility model belongs to the technical field of automobile design and manufacturing, and particularly relates to an anti-shake device for an upper frame of a vehicle door. Background Art

[0002] At present, China's automobile industry is becoming increasingly mature, and automobile manufacturers are placing higher and higher demands on automobile CAE. Among them, the problem of door and window frame shaking has not been well solved. The existing inner panel design method is difficult to meet the automobile manufacturers' requirements for door and window frame stiffness at one time. It often requires repeated changes and verifications to achieve the target value, which wastes a lot of time and increases design costs. At the same time, the existing door and window frame design methods all increase the stiffness of the inner panel itself by increasing the cross-sectional depth and width of the upper frame, which has a great impact on the window frame stamping and the transmittance of the glass. Based on this, it is necessary to develop a structure to prevent the door and window frame from shaking in order to effectively solve the above problems. Summary of the Invention

[0023] The present invention will be further described below in conjunction with the embodiments:

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this utility model, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0026] like Figure 1-Figure 4 As shown, the present invention provides an anti-shake device for the vehicle door upper frame. First, a screw 1 is passed through the holes a1 and b1 of the side panel outer panel 4 to pre-tighten the support block 2 and the waterproof gasket 3 to the side panel outer panel 4. Then, the nut 5 is connected to the screw 1 to fasten the support block 2 and the waterproof gasket 3 to the side panel outer panel 4. Finally, the c1 of the inner panel 6 is overlapped on the support block 2, so that the vehicle door inner panel 6 and the side panel outer panel 4 are matched together, thereby preventing the vehicle door window frame from shaking when the car is driving on bumpy roads, and achieving better sealing and noise reduction effects.

[0027] Specifically, the vehicle door upper frame anti-shake device of the present invention includes two screws 1, a support block 2, two waterproof gaskets 3 and two nuts 5.

[0028] The support block 2 is made of nylon inside and flocking outside. Figure 5 As shown, the support block 2 is an L-shaped structure with two 7mm diameter screw holes spaced 30mm apart at the overlap with the side panel 4, allowing it to be installed on the side panel 4. The side panel 4 also has 8mm diameter holes a1 and b1, spaced 30mm apart, located on the upper frame of the side panel 4, approximately 1000mm from the front of the side panel 4. This prevents the window frame from shaking when the car is driving on the road, improving sealing and noise reduction.

[0029] The two screws 1 are C-type hexagonal pan head flange self-tapping screws with a diameter of 4.8 mm and a length of 16 mm, which can be respectively passed through the holes a1 and b1 on the side outer panel 4 and locked with the two nuts 5.

[0030] Multiple waterproof gaskets 3 are installed between the support block 2 and the side outer panel 4. The waterproof gaskets 3 are made of PUR material, are 10mm in diameter, 0.5mm thick, and have a 4.8mm screw hole in the middle. There are two waterproof gaskets 3.

[0031] Section C1 of the door inner panel 6 is a 70mm long boss structure. To prevent window frame vibration between the door inner panel 6 and the side panel 4 during driving, a support block 2 is fixed between them to prevent vibration. During the overlap, section C1 of the door inner panel 6 must be overlapped onto the surface of the support block 2 after the support block 2 is secured to the side panel 4.

[0032] To install the vehicle door upper frame anti-shake device of this invention, first insert two screws 1 through holes a1 and b1 in the side panel 4, respectively. Then, pre-tighten the support block 2 and two waterproof gaskets 3 to the side panel 4. Then, use two nuts 5 to fasten the two screws 1, support block 2, and two waterproof gaskets 3 to the side panel 4. Finally, overlap section c1 of the door inner panel 6 on the support block 2.

[0033] The anti-shake effect of the vehicle door upper frame anti-shake device of the present invention is shown in Table 1 and Table 2. Among them, the modal frequency without the upper frame anti-shake device is shown in Table 1, and the modal frequency with the upper frame anti-shake device is shown in Table 2.
