Description

Technical Field

[0001] The invention belongs to the field of automobile accessories, and in particular relates to a multifunctional automobile roof handle development tool. Background Art

[0002] In automobile development, the requirements for automobile handles, especially passenger car handles, are relatively high. In addition to a good appearance match, there are many other requirements: the handle must have a certain rigidity, and must meet certain human-machine interaction requirements (such as hand feel). After the handle is used, it also has high requirements for its return to its original position, so it is necessary to test and determine parameters such as handle springs and damping.

[0003] The current handles basically have springs and damping components. Figure 1 , 2 However, the repeated adjustment of these comfortable areas is mainly based on experience, and then the product is repeatedly debugged in the later stage, and sometimes there is no solution. For example, after the handle is released (that is, after use), it can rebound to its original position smoothly under the action of the spring, but the handle feels strong; and when the handle feels good, it is found that the spring force is insufficient, and it cannot rebound to its original position under the action of damping, gravity, friction, etc.

[0004] In addition, the tooling invested in the later stage is often for special parts, and the installation spacing and posture of the handle are all fixed and cannot be adjusted. After this part is used up, it cannot be used for other project development. If the project is completed, it will have no other practical use except being treated as waste. The existing tooling is special and requires a lot of investment; the existing tooling is invested in the later stage of the project and cannot guide the development in the development stage. Summary of the invention

[0005] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a multifunctional automobile roof handle development tool.

[0006] Technical solution: In order to solve the above technical problems, the present invention provides a multifunctional automobile roof handle development tooling, including a working base, a base, a handle and a fixing device, the fixing device is used to fix, lock and maintain the adjusted handle, the base is connected to the rotating fixing frame through a horizontal rotating axis, the rotating fixing frame is connected to the working base through a vertical rotating axis, the base is provided with a guide rail, one end of the handle is connected to the guide rail, and the other end is fixed to the base.

[0007] Furthermore, the handle is connected to the base via a handle base.

[0008] Furthermore, a handle rotation axis is provided between the handle and the handle base.

[0009] Furthermore, a groove is provided on the working base.

[0010] Furthermore, the base is arranged on the groove.

[0011] Furthermore, the guide rail is in the form of an elongated slot, and the position of the handle is adjusted through the elongated slot.

[0012] Furthermore, the handle is made of plastic material.

[0013] If the present invention has certain tooling to simulate the installation environment at the beginning, it is bound to accurately lock various technical parameters in the early stage of development and reduce the adjustment in the later stage. Based on this idea, the present invention provides a multifunctional tooling for the handle, which can more realistically simulate the installation environment of different models. The key design parameters of the handle can be locked more accurately in the early stage.

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, a multifunctional automobile roof handle development tooling includes a working base 14, a base 9, and a handle 5. The base 9 is connected to a rotating fixed frame 13 through a horizontal rotating shaft 10, and the rotating fixed frame 13 is connected to the working base 14 through a vertical rotating shaft 12. A guide rail 11 is provided on the base 9, and one end of the handle 5 is connected to the guide rail 11, and the other end is fixed to the base 9. The handle 5 is connected to the base 9 through a handle base 8. A handle rotating shaft 2 is provided between the handle 5 and the handle base 8. A groove is provided on the working base 14. The base 9 is arranged on the groove. The guide rail 11 is an elongated slot.

[0022] like Figure 2 As shown, it is a schematic diagram of a common handle in the installation position, including a mounting base 1 at two handles, a handle rotating shaft 2, a spring 3, a damper 4, a handle with a rotating handle 5, a ceiling 6 or other matching objects, and 7 connecting bolts (or other types of fasteners). The spring 3 and the damper 4 are installed on the rotating shaft 2, and are often hidden inside the mounting base 1 and cannot be seen. Therefore, 1, 2, 3, 4, and 5 are all sub-parts of the handle itself. The mounting base 1 and the ceiling 6 are usually connected with a connecting bolt 7. However, for the sake of aesthetics, the connecting bolt 7 is hidden inside and is generally not visible from the outside. Since these details are irrelevant to the invention, they will not be described in detail.

[0023] In this embodiment, in order to overcome the shortcomings of the prior art, the handle base 8 is made to be adjustable in distance to meet the needs of handles of different lengths, such as Figure 1 As shown, a movable fixed handle fixture (which can also be used as a later inspection fixture) is composed of two metal handle bases 8, a base 9, a long groove guide rail 11, a horizontal rotation axis 10, a vertical rotation axis 12, a rotation fixing frame 13 and a working base 14, and some necessary fixing devices are used to fix, lock and maintain the adjusted fastening device.

[0024] This embodiment adjusts the center distance: the handle base is a metal handle base used to fix the handle, the handle base is used to simulate two handle installation points on a real vehicle, the handle base is fixed by connecting bolts, the distance between the handle bases can be adjusted, and the handle base on the left side can be adjusted in length along the long slot guide rail on the base to meet the installation of handles of different lengths;

[0025] Angle adjustment in this embodiment: Since the handle rotation axis 2 of the handle 5 is actually at any angle in space, that is, it is not necessarily horizontal or at other special angles. This requires that the tooling can provide two angles (because the angle between the handle rotation axis 2 and gravity and the rotation angle between the handle 5 and its own handle rotation axis 2 are related, only two angles are needed, that is, in the horizontal direction, it has nothing to do with the direction of the front of the vehicle). Therefore, the entire base 9 can rotate around the horizontal rotation axis 10 to a specified angle and can be fixed (can be fixed by studs); the vertical rotation axis 12 can be rotated as a whole to a specified angle in the direction perpendicular to the paper. The vertical rotation axis 12 is connected to the working base 14 to provide a stable and sturdy mounting base for the entire universal device. In this way, the actual state of the handle being placed horizontally on the entire vehicle can be adjusted.

[0026] In the early stage of development, the handle 5 can be realized by rapid prototyping technology. In this way, the actual state of the sample can be simulated on this workbench in the early stage (due to factors such as gravity, the rotation system composed of damping, springs, and handles is closely related to its actual physical state). Because the connection method may sometimes be uncertain, the fixed connection bolts 7 can also be interchanged in different types on the handle base 8. In this case, this tooling can completely replace the later inspection fixture and avoid the repeated production of special inspection fixtures.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
