Description

DESCRIPTION DOORS, LUGGAGES, MOVING LIKE HOODS AND/OR HATCHBACK DOORS HINGE FOR PARTS The object of the present invention is motor vehicle doors, trunks, hoods, hatchbacks. for moving and supporting doors and similar moving parts is a suitable hinge.

As it is known, motor vehicles cause the moving parts of the body to close. or it can be equipped with servo-mechanisms that help it open. this type solutions, for example in “upper segment” vehicles for civil use and especially in heavy or on commercial/industrial vehicles supplied with bulky door/hatchback doors can be found.

Known types of servo controllers are used to open or close the door or the hood or to properly move another part that needs to be closed. to apply an "additional force", usually in reference to what the user is applying (even in some cases, just using an on or off command) without the need for an intervention by the user who needs it. to apply the full force) with suitable hydraulic or pneumatic actuators is carried out. In general, these above-mentioned devices are according to the kinematic articulation mechanisms of doors and hatchback doors It is mounted separately.

Although widely used, the above-described prior art it has some disadvantages that limit its usefulness; specifically, especially “fixed” parts and “moving” parts of the body (these are fit tightly to each other) to the working volumes located between Servo of the known type considering that they must be placed 37989.01 The overall dimensions of the drive mechanisms are quite large. One such solution is is shown. In addition, servo actuators of a known type are the disadvantage lies in their cost and their unique conveniences.

In fact, hydraulic or pneumatic elements are obvious for the working fluid/gas. level of reliability and hermetically sealed, which is inevitable. structure and equipment (gaskets, sliding components and materials). An example of such a solution and the servo control mechanisms working with liquids/gases at ambient temperature The fact that it is particularly sensitive to changes should be kept in mind. Actually, this type variations affect the viscosity and therefore the so-called “equivalent” of the working fluid. directly affects the modulus of elasticity and sometimes the entire mechanism makes the movement too strong or too weak. The present invention therefore, motor vehicle capable of overcoming the above-mentioned limitations hoods (such as doors, hoods, trunks and/or hatchback doors) aims to design a hinge for its moving parts. The present invention mainly to the opening of the aforementioned "moving parts of the hood" and better and more practical use and at the same time considerable overall compactness and as low as possible functional use to bring together production costs aims to design a hinge to be presented.

In addition, existing invention, for example, through aftermarket upgrades or maintenance pre-assembled elements during procedures or repair work. aims to design a hinge that can replace it. defined technical task and stated objectives in one or more of the appended claims movable motor vehicle bodyworks having the specified characteristics This is largely accomplished with a hinge for the parts.

A preferred, but not limited to, a hinge according to the present invention 37989.01 The description of its configuration is by way of an approximate and non-limiting example. are given and illustrated in the accompanying figures, where: - Figure 1 shows that the hinge (a "closed" of the movable body part) according to the invention a schematic one in a first operating configuration (corresponding to is the image; and - Figure 2 shows that the hinge (an “open” part of the movable body part) according to the invention a schematic one in a second operating configuration (corresponding to is the image.

Referring to the accompanying figures, the hinge as a whole according to the present invention (1) reference numeral and largely (of a chassis and/or a a first hooking section (2), which can be provided to a fixed part of the bodywork, a kinematic articulation coupled to the first hooking section (2) mechanism (3), and the kinematic articulation mechanism (3) (and which can also be attached to a moving part of a chassis and/or a body it includes the second hooking section (4). The existing hinge is also simultaneous as a servo control associated with the first and second hooking sections (2, 4). contains the unit (5).

At this point, the difference between the present invention and the state of the technology presented above the difference should be stated. In fact, the structural and functional of the servo controller based on its composition and that this unit is extremely compact and or an active element that operates without the interference of gases. As a result, high performance levels are achieved in terms of generating active power. and at the same time a significant reduction in overall dimensions is achieved. is being done.

In more detail, the kinematic articulation mechanism (3) is properly It can be observed that it describes a segmented quadrilateral, and thus includes the following: 37989.01 - a first pin (3b) (connecting to the first hooking section (2)) and (to it) having a second pin (30) corresponding to the second hooking section (4) a first connecting rod (3a) with - a third pin (3e) (connecting to the first hooking section (2)) and (to this with a fourth pin (31°) which is connected to the corresponding second hooking section (4) a second connecting arm (3d) with On its side, the servo control unit (5), at least (to the door/hatchback door) connected and thus capable of transmitting the servo control action) to exert a so-called "active force" on the second hooking section (4) Suitable at least one actuator (Sa).

According to the needs at hand that are not expressed in the claims, the servo control unit (5), It can also be linked to components of the kinematic articulation mechanism or more generally, mounted on a hinge that was previously installed/in use on the vehicle. can be removed/detached from it. For this purpose, the servo control unit, without the use of vehicles and maneuvering external components and/or "extra movement" of the moving part without the use of can use.

In the present invention, the actuator 5a has at least one preloaded axial spring. contains. This spring provides the aforementioned “active force”, fifth pin (5b) and in linear proportion to an extension extending between the sixth pin (50) a fifth pin (5b) and a sixth pin (5c), respectively. through the first and second hooking sections (2 and 4). is connecting.

Referring to the attached figures, axially inserted in the preloaded spring that there is a spring guide element (6), as well as a spring-guide coaxial with element (6) and compatible with fifth pin (5b) or sixth pin (50) 37989.01 Observing that there is an end housing (7) inserted as possible.

If it is desired (or In other words, doors and/or doors that vary in terms of surface and weight. single unit that can be adapted for use in servo control of hatchback doors. object is to be produced), a preload adjustment unit for the actuator (Sa) available to be found. This adjusting unit can be shaped in any desired shape, even even with respect to prior art technologies. Regarding the positioning of the pre-load adjustment unit, this position is it coincides with the guide element (6) or the end housing (7). Moreover, the preload adjustment unit for the servo controller for the moving part of a door/hatchback door during procedures an extra additional movement area of the moving part of the door/hatchback door, it can be made usable without any element being maneuvered.

Again, to adapt the present invention to different working situations or in various settings. at least one geometric adjustment element (8) to enable the use of available. This geometric-adjusting element is connected to the fifth and/or sixth pin (5b). and/or 50) to change a relative position of the first and/or second can be attached to the hooking section so that the “lever arms” and therefore, it also changes the servo control motion modes.

If the functions of the present invention are to be increased further, this damping damping such that the element is suitable to produce a damping force. element can be conveniently mounted on the hinge (1).

This damping force is combined with the active force created by the servo control unit (5). 37989.01 applied in a coordinated manner and this damping compared to prior art element, preferably a frictional force (or in each case two of the same hinge) a displacement and/or relative alignment between force) is suitable for production.

An object of the present invention is also to cover the body and the pre-existing a specified number of moving parts (for example: movement relative to the bodywork) doors, hoods, trunks and/or hatchback doors) it is a vehicle. This motor vehicle is as described above and specified in the following claims. includes at least one anchor such as the body and at least one of the "moving parts" mentioned above).

The invention achieves a number of advantages.

In fact, thanks to the special structural design of the existing hinge, the device is quite limited. It can be installed in spaces with a servo control function and the kinematic It can be integrated with the articulation function. In addition, working fluids or gases, do not use this device due to environmental factors such as temperature. become virtually independent of functional changes that occur brings.

Also, the present invention includes a door/hatchback door or similar moving object. significantly facilitating the opening and the assistance of additional mechanical stops. It has the ability to hold them in an open position.

Another advantage provided by the existing hinge is during the closing step. any door/hood/hatchback that may be mounted around the door. is offered. In fact, the above-described and the following claims the servo controller also acts as a “brake” during shutdown, thereby preventing violent shutdown and therefore the transmission of surge voltages. 37989.01 prevents.

Finally, the reduced total number of parts and working fluids or The present invention of the absence of gasses is extremely reliable, easy to maintain and First of all, it can be observed that it makes it economical.
