Description

Navigation device for fixed mounting of car steering wheel {DEVICE FOR STATIONARY NAVIGATION FOR MOUNTING AUTOMOBILE'S HANDLE}

The present invention relates to a fixed navigation device for the steering wheel of the vehicle, but fixedly equipped with a navigation device in a structure designed to give priority to the magnetic rotation force of the steering wheel by the magnetic force, even when rotating the navigation itself more complete by blocking the fluidity The present invention relates to a fixed mounting navigation device for a vehicle steering wheel to ensure a fixed navigation state.

Since the steering wheel switch mounted on the steering wheel rotates with the rotation of the steering wheel, the driver has to pay attention to the rotating steering wheel switch, which causes a large apostle. Fixing the same device to the handle also made it hard to think of the use itself, because it doesn't guarantee navigational identification while driving.

In the case of Korean Utility Model Registration No. 426356, 'Automatic steering wheel with integrated navigation,' the navigation is provided by providing a space in the steering shaft of the steering wheel and providing a navigation fixed shaft to maintain the fixed state even when the steering shaft rotates in the space. It is posted to be fixed to the navigation fixed shaft to maintain a fixed state even when the handle is rotated.

However, according to the above technique, it can be seen that the navigation fixed shaft is embedded in the steering shaft, but it is not known whether the navigation fixed shaft is continuously embedded from the lower part of the steering shaft, and if so, the structure of the known vehicle steering system is changed. In addition to the need to raise the cost due to the change in the structure of the vehicle, as well as to ensure that the navigation is securely fixed only on the navigation fixed shaft that must be made of a diameter smaller than the steering shaft to ensure a safe fixed state of the navigation The disadvantage of not being able to do this is pointed out.

1 is a perspective view showing a schematic configuration of the prior art patented by the applicant.

The structure shown in FIG. 1 is patented by the present applicant as a handle mounting structure of a fixed handle switch for automobiles in Korean Patent No. 782053, and may be referred to as a mounting structure of a handle switch in a handle to solve the above problem.

Patent No. 782053 discloses a handle having an internal predetermined space in which the spokes 2 are radially connected toward the hub 3 to which the handle shaft 4 is connected in the annular rim 1; The through portion 53 is provided at the center portion to be coupled to the end of the handle shaft 4 protruding on the hub 3, and the anti-rotation bearing assembly 55 is formed around the through portion 53. In the first magnet module 50 made of a magnet 52 is formed on the outer peripheral surface of the handle shaft (4); The handle switch 10 formed on the inside of the rim 1 is fixed to the first magnet module 50 by a bracket 40 and horizontally spaced apart from the rim 1 on a top surface of the rim 1. A housing 30 including a panel 20 provided thereon; A second magnet module 60 formed of a magnet 62 and fixed to a predetermined portion of the handle shaft 4 positioned at the lower end of the hub 3; and consisting of the first and second magnet modules 50 and 60; The first magnet module 50 is fixed to the handle shaft by the anti-rotation bearing assembly 55 while the magnetic force generated by the interaction of the magnets 52 and 62 is greater than the rotation force of the handle. The switch is fixed even when the handle is rotated.

In other words, the patent has the advantage that the magnetic force can be mounted to the handle switch and other airbags, even navigation in the handle in a state that ensures a more stationary force by the magnetic force than the rotational force of the handle.

By the way, the housing having a handle switch is supported on the first magnet through the bracket, the first magnet is maintained by the anti-rotation assembly, if the user only rotates the housing occurs separately from the magnetic It can be pointed out that the problem that the housing itself is moved by minute play or inertia is fine.

Therefore, there is a need for an improved technology that enables a more perfect fixed state even when the housing itself including the handle switch and the navigation, as well as the rotation of the handle, is required.

The present invention has been made in order to overcome the problems of the above technology, as shown in Patent No. 782053 to provide a base for fixing the navigation by magnetic force, but the restorability is fixed to the first magnet or other fixture When the fixed module is not rotated, the fixed module is inserted into the groove provided in the lower part of the housing to fix and support the housing. However, when the handle is rotated, the resilient fixed module is deformed (folded rotation or up and down movement) so as not to interfere with the rotation of the handle. To ensure handle rotation.

Another object of the present invention is to attach a magnet to the restorable fixing module so that one component of the handle is deformed by itself before being adjacent by the repulsive force, thereby preventing the possibility of mechanical wear.

Still another object of the present invention is to deviate from the handle rotation path of the rotation direction of the resilient fixing module so as to minimize the possibility of being hindered by the handle rotation.

A further object of the present invention is to modify the structure of the handle so that the restorable fixing module can be properly fixed to the external fixture.

In order to achieve the above object, the navigation device for fixed mounting of the automobile handle according to the present invention, by using the magnetic force relationship between the first magnet and the second magnet steering wheel switch or navigation to maintain a fixed state in the steering wheel even when the steering wheel In the handle structure equipped with a handle bar having a handle bar connected from the circumferential portion of the annular shape to the handle shaft, wherein the portion other than the handle bar connection portion comprises a handle having an open state; A housing having one of a navigation device and a handle switch at one portion, the housing being located in the space within the handle and coupled to an upper portion of the handle shaft via a rotation preventing bearing assembly and having a plurality of insertion grooves at a lower surface thereof; ; Located on the line of the rotation path of the handle bar and fixed to any one of the first magnet to the outside of the handle, it is composed of a pivoting portion that can be folded by an external force and a support portion for supporting the pivoting portion, The rotating part is inserted into and fixed to the insertion groove to support the housing, and when the handle bar hits the rotating part by the rotation of the handle, the rotating part is folded to secure the rotation path of the handle bar; It is characterized by including.

In addition, the contact surface of the rotating part, which is the point at which the handle bar is hit, is formed upright by tilting 45 degrees on a straight line from the handle shaft to the rotation path of the handle bar, the rotating part of the handle bar in the handle shaft It is characterized by being foldable rotation in accordance with the straight line direction leading up to the rotation path.

In addition, when the resilient fixing module is fixed to the handle external fixture, the support is extended to a predetermined length in an upright to bent state between the fixing body and the resilient fixing module; characterized in that it is further provided.

According to the navigation device for a vehicle steering wheel fixed mounting according to the present invention,

1) It is possible to mount in the steering wheel in the state of ensuring the maximum fixing force of the navigation,

2) If the navigation itself is rotated without the steering wheel, the navigation can be completely prevented.

3) the problem of increased mechanical wear or fatigue due to friction between the components for maintaining the navigation fixed state, and the problem of friction noise can be minimized,

4) The steering wheel itself can be slimmer at the same time.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numerals in each of the drawings refer to like elements.

Figure 2 is a perspective view showing a schematic configuration of a navigation device for fixed steering wheel mounting according to the invention, Figure 3 is a side cross-sectional view of FIG.

As can be seen from Figures 2 and 3, the device according to the present invention has a configuration and structure substantially similar to the patent 782053 'Handle mounting structure of the fixed handle switch for automobile', the magnetic force is greater than the rotational force of the handle The housing 30, which is fixed by the magnetic force even when the handle is rotated, is based on having the state fixed to the handle without rotation. Therefore, for the configuration similar to Patent No. 782053, reference to specific functions and operations will be omitted.

In addition, the device included in the housing 30 may include a handle switch, a navigation, an air bag, as well as other devices suitably required in other vehicles mentioned in the following description.

The device according to the present invention has a bracket (shown in FIG. 1) for fixing and supporting the housing 30 to the first magnet module 50 between the housing 30 and the first magnet module 50 in the above patent 782053. At the same time, the lower portion of the housing 30, the mounting position of the first magnet module 50 and the structure of the hub are modified.

Specifically, referring to FIG. 2, the hub having an annular shape positioned at the end of the spoke 2 as shown in Patent No. 782053 does not have an annular inner surface enclosed shape but rather an extension line as an annular shape once. In this state, a plurality of handle bars 45 extending from the handle shaft 4 toward this extension line (preferably between two and four) are formed and the remaining portions are open. Has

That is, the hub 41 plays a basic role of transmitting the rotational force of the rim 1 to the handle shaft 4, which transmits the rotational force to the handle shaft 4 along a plurality of spokes 2 formed on the side of the handle. A means for this is required, that is, the handle bar 45 formed on the hub 41 is formed to finally transmit the rotational force transmitted from the spoke 2 to the handle shaft 4. The handle bar 45 may extend horizontally toward the handle shaft 4 at the peripheral portion of the hub 41 (an annular extension line), but the handle bar 45 may be extended at the peripheral portion of the hub to accommodate various shapes of the handle. It may extend obliquely toward the handle shaft 4 portion in the direction / down direction.

In addition, the position at which the end of the handle bar 45 is fixed to the handle shaft 4 is located between the housing 30 and the first magnet module 50 (in this case, the bracket of FIG. 1 is caught by the handle bar. Should be installed as a resilient fixing module according to the present invention) or between the first magnet module 50 and the second magnet module 60 (in this case, the resilient fixing module is left with the bracket of FIG. It may be said that it is most preferable) (upright position between the magnet module).

In the first embodiment according to the invention shown in FIGS. 2 and 3, the handle bar 45 is located between the housing 30 and the first magnet module 50 so that the first magnet module 50 is handle bar. It can be seen that it is located below 45.

In addition, as can be seen in Figure 3, the housing 30 is provided with a groove 32 in the lower surface center portion so that the upper end of the handle shaft 4 can be coupled thereto so that the bracket as in Patent No. 782053 It is possible to ensure the support state without itself, but on the outer circumferential surface of the groove 32, as in the configuration state in the first magnet module 50, the anti-rotation bearing assembly 55 is formed, the handle shaft 4 At the time of rotation, the housing 30 is configured to have a fixed state.

The anti-rotation bearing assembly 55 allows the housing 30 to have a fixed position without rotation even when the handle shaft 4 is rotated. However, only the anti-rotation assembly 55 depends on the fixed state. If the fixing force is weak or can be rotated by the rotational force acting on the housing 30 itself, as in Patent No. 782053, the first magnet module 50 and the second magnet module ( 60), it is desirable to be designed to have a lower fixed supporting force by the perfect assistance of the magnetic force.

The resilient fixing module 100 according to the present invention is located in an open space formed between the hub 41 and the handle bar 45 having an annular circumference and at the same time the first magnet module (see FIGS. 2 and 3) to others. It is supported by a non-rotating fixture (see FIG. 7), which is installed in the rotation path of the handle bar 45 when the handle is rotated, but the handle bar 45 is formed to have a height that will strike it. .

The resilient fixing module 100 has a state that is fixed to the first magnet module 50 having a fixed state even when the handle is rotated, or is not rotated like the first magnet module 50 even when the handle is rotated. It is also possible to fix it via a support 140 which extends straight or curved downwards to a surface of other configuration that does not, for example, a separate control box designed to be non-rotating or the vehicle wall around the handle.

That is, the core of the device according to the present invention, so that even when rotating the housing 30 itself, not the handle so that the housing 30 is not rotated even finely, and at the same time to make the structure of the handle more slim (slim) It is to design a resilient fixing module 100 having a function to have a variety of positions and structures.

As mentioned above, the handle bar 45 mounted on the hub 41 can be designed to be installed at various positions of the handle shaft 4, that is, the handle bar 45 to the restorable fixing module 100. It should not be construed that the formation position of is limited to the drawing (Figs. 2, 3 or 7).

Briefly explaining the basic principle of the device according to the present invention, in a state in which the handle is not rotating, the restorable fixing module 100 is inserted into the insertion groove 31 formed on the lower surface of the housing 30 and fixed to the housing 30. While maintaining the housing 30 in a fixed state even when rotating itself, when the handle is rotated and the handle bar 45 hits the restorable fixing module 100, the restorable fixing module 100 is folded downward / up and down Moved to secure the movement path or space of the handle bar 45, and after the handle bar 45 has passed, the restorable fixing module 100 is returned to its original position so that the support state and the handle bar of the restorable fixing module 100 are returned. It is to ensure the movement path of (45) at the same time.

The resilient fixing module 100 according to the present invention can be made in a foldable pivoting manner and a vertically moving manner based on various embodiments, and the basic idea of the present invention is not limited to a specific manner, but in the following manner of foldable pivoting This will be described in more detail.

4 is a partial perspective view illustrating a method of pivoting a restorable fixing module by a hinge, and FIG. 5 is a plan view of FIG. 4 illustrating a relationship between a restorable fixing module and a handle bar.

Resilient fixing module 100 according to the present invention is upright on the surface of the first magnet module 50, as shown in Figures 2 and 3 is basically formed to support the housing 30, 2 to 4 It is formed as a but is formed horizontally with the hitting portion of the handle bar 45 of the trajectory (rotation path) of the handle bar 45, specifically, the pivoting portion 110 and the pivoting portion 110 which is a folding pivot It consists of a support 120 that includes a spring-loaded hinge (spring hinge) 130 so that it can be rotated while having a restoring property.

In addition, an insertion groove 31 having a number and a shape corresponding to the restorable fixing module 100 is formed on a lower surface of the housing 30.

The insertion groove 31 may be chamfered or rounded at the corners or the edges in order to ensure the insertion and release of the pivot 110 properly. Correspondingly, the pivot 110 ) Also have the same shape.

Rotating portion 110 is a portion that is rotated by being hit by the handle bar 45 directly when the handle bar 45 rotates, protruding in a three-dimensional shape from the support portion 120, such as a rectangular parallelepiped, and a specific shape It is not limited to.

However, as shown in FIGS. 4 and 5, assuming that the steering shaft 45 has a waterline installed at the installation point of the pivot 110, the contact surface of the pivot is inclined at approximately 45 degrees. Do.

By the spring hinge 130 provided in the support 120, the pivoting direction of the pivoting part 110 is made to coincide with the direction of extension of the waterline, so that the contact surface of the pivoting part 110 is connected to the handle bar 45. When hit by the pivoting unit 110 is not rotated in the opposite direction of the strike direction (direction coinciding with the hitting direction), but folded in a 45 degree inclination direction (waterline direction to the handle shaft in Figure 5) in the strike direction We will meet.

 As can be seen from FIGS. 4 and 5, a bent portion is provided at one portion of the handle bar 45 (that is, the portion that strikes the pivoting portion). The bent portion is formed to make sufficient surface contact with the hitting surface of the pivoting part, and the first bent surface 45a and the second bent surface 45b generated by the bent portion immediately strike the pivoting part 110. If the handle bar 45 rotates clockwise / counterclockwise along the circle trajectory (rotation path), the two sides are formed at different angles, not parallel to each other, so that both surfaces of the rotating part 110 are sufficiently flush with each other. It is made for contact.

The bending angles of the first and second bent surfaces 45a and 45b by the bent portion are variously changed depending on the distance from the handle shaft 4 to the trajectory of the handle bar 45 to the shape of the pivot 110. This may be possible, but it is more preferable that the pivoting part 110 is folded so as to slide in the lateral direction while making contact with the contacting surface of the pivoting part 110 as much as possible. This will be described later, but when the rotating part 110 is in contact with the handle bar 45 is to minimize the friction.

Referring to the operation of one embodiment according to the present invention having such a structure, first, when the handle is not rotating, the insertion groove 31 provided with the rotating part 110 of the restorable fixing module 100 is provided in the lower portion of the housing 30. It is inserted and fixed in the) takes the state supporting the housing 30 in a state in which the restorable fixing module 100 is upright. Therefore, when the housing 30 itself is rotated by this structure, its rotational force is a force that resists rotational prevention in the two anti-rotation assemblies 55 (that is, mounted on the housing lower part and the first magnet module respectively). By overcoming the problem, the housing 30 can be appropriately prevented from being rotated little by little at a fixed position.

When the handle is rotated, the bent portion of the handle bar 45 hits the contact surface of the pivot 110 and the impacted pivot 110 has a contact surface of the handle bar 45 at the handle shaft 4. Since it is inclined in a straight line direction inclined at 45 degrees from the straight line (the above-described waterline) to reach the rotation path, it is inclined in a direction 45 degrees away from the hitting direction (waterline direction described above) as if slipping. That is, the tangent of the point hit by the rotating part 110 in the rotation path of the handle bar 45 and the straight line indicating the direction in which the actual rotating part 110 is rotated to form an angle of 45 degrees to each other, thereby When the rotating part 110 is configured to fall in the direction corresponding to the direction, the resilient property of the rotating part 110 is more smoothly and naturally guaranteed than when the rotating part 110 is configured to fall, and thus, the friction part due to the contact is minimized.

The reason why the rotating part 110 is formed at an angle of 45 degrees is to enable the same sliding folding rotation in both directions when being hit in both directions including both clockwise and counterclockwise directions.

When the handle bar 45 strikes the pivot 110, the pivot 110 is inclined while the upper portion of the pivot 110 is inserted into the insertion groove of the housing 30 by the impact and then starts to separate. And the spring hinge 130 retains elastic energy. As the pivot 110 is inclined, the handle bar 45 continuously rotates through a space generated in the upper portion of the pivot 110. It is secured, so that the handle bar 45 can be continuously rotated to the upper space of the inclined rotating portion 110 without the obstruction of the rotating portion (110).

After the handle bar 45 passes through the upper space of the pivoting pivot 110, the pivot 110 is upright again by the restoring force of the spring provided on the spring hinge 130, and the pivoting portion is upright. The eastern part 110 enters into the insertion groove 31 of the housing 30 again to fix and support the housing 30 again, and the handle bar 45 is rotated 110 while the handle is rotated clockwise or counterclockwise. This process is repeated in a series of successive hits).

That is, when the handle is not rotated, the rotating part 110 of the restorable fixing module 100 maintains an upright state, and serves to fix and support the housing 30 together with the anti-rotation assembly 55. When this rotation is inevitable to rotate the rotating part 110 of the resilient fixing module 100 to make the movement path of the handle bar 45 is to be folded.

6 is a conceptual view showing a modification in which the magnet is mounted on the resilient fixing module and the handle bar.

To prevent the problem that the handle bar 45 to the rotating part 110 is easily worn by a large noise or direct mutual contact when the contact surface / bending portion of the rotating part 110 and the handle bar 45 makes a surface contact. To this end, magnets made of the same pole are formed on the first and second bent surfaces 45a and 45b of the handle bar 45 and the contact surfaces of the pivoting part 110 that contact them to generate bilateral repulsion when they are adjacent to each other. Formed.

By this magnet, when the handle bar 45 rotates and is adjacent to the rotating part 110, a repulsive force is generated between the contact surface of the handle bar 45 and the rotating part 110 to push the rotating part 110. (Folding pivoting), by allowing the pivoting section 110 to start folding rotation before contacting the handle bar 45, it is possible to fundamentally prevent the occurrence of friction noise and abrasion phenomenon by direct contact.

7 is a perspective view showing the configuration of another embodiment of the device according to the present invention.

In the above-described embodiment, the restorable fixing module 100 is fixedly positioned on the first magnet 50, whereas in the other embodiment shown in FIG. 7 according to the present invention, the restorable fixing module 100 is separately provided. It is shown that the support 140 is supported by a separate fixture.

That is, in the embodiment of FIGS. 2 and 3, since the restorable fixing module 100 is located on the first magnet module 50, the movement to the inertia of the anti-rotation assembly 55 when moving the housing 30 itself is reduced to the play or inertia. There may be a possibility that the movement of the housing due to, but as shown in Figure 7 is fixed to the restoring fixed module 100 in a portion of the vehicle body that is fixed regardless of the rotation of the handle around the handle (this is referred to as 'fixing body') When supported by the support 140 can perform a function that can more completely prevent the flow of the housing (30).

The support 140 may be freely bent as shown in FIG. 7, and may extend from the outside of the handle to the fixed body installed in the loading place.

8 is a conceptual diagram exemplarily illustrating a state in which a navigation is mounted in an inner space of a rim.

The housing 30 can be equipped with a navigation switch 15 as shown in FIG. 8 as well as the handle switch 10 to the airvec, and the tilt function, that is, the navigation 15 of the currently known The ability to adjust the angle to ensure viewing angles can also be combined, giving the driver the ability to concentrate on driving safely without having to distract from the steering wheel to see the navigation away from the steering wheel.

At this time, in the case of wiring, it is possible to provide a proper space to be treated as the space inside the handle shaft and to prevent entanglement at a predetermined portion of the handle shaft, and to be drawn out to the space. (The actual handle is not rotated indefinitely, but only two or three turns in one direction, so this can be done without difficulty.)
