Description

The invention relates to a vehicle loading flap unit for covering a charging connection on the vehicle.

Vehicle loading flap units for covering a loading connection on the vehicle are already known from the prior art. These usually consist of an outside loading flap, which is flush with a vehicle shell of the vehicle, and an inside loading flap, which is located on a charging connection. In order to be able to insert a charging plug into the charging connection, the outer charging flap must first be opened and in a further step the inner charging flap must be removed from the charging connection. After the loading process, the steps must be repeated in reverse order.

The object of the invention is to provide a vehicle loading flap unit which ensures that the loading connection is opened and closed more easily and efficiently.

The object is achieved according to the invention by a vehicle loading flap unit for covering a charging connection on the vehicle, which comprises a plate-like, outer flap and a protruding push-slide button provided on the inside of the outer flap, which has a spring section which is elastic in the closing direction of the outer flap for opening or unlocking the outer or an inner flap and a harder, less elastic, end-face sliding section than the spring section, which is attached to the spring section. In the closed state of the vehicle loading flap unit, the push-slide button rests with its front-side sliding section against an inner flap which covers a charging connection. The spring section of the push-slide button is compressed between the outer flap and the inner flap and is thus under tension.

When unlocking the outer flap by e.g. a push-push mechanism relaxes the spring section and thereby pushes the outer flap outward away from a vehicle shell. A user can easily reach into the resulting gap between the vehicle shell and the outer flap and open the outer flap completely.

In the course of the complete opening of the outer flap, the front-side sliding section of the push-slide button can touch and open a locking device of the inner flap, if one is present.

In one embodiment, however, no locking device is provided on the inner flap.

The spring section is preferably a rubber buffer, in particular a rubber bellows. This gives the spring section its elastic property.

In particular, the spring section consists of a different plastic than the sliding section. The material of the sliding section is preferably harder and less elastic than that of the spring section. As a result, the friction between the sliding section and a vehicle component sliding on the sliding section can be reduced, which on the one hand leads to an extended service life of the push-on slide button and on the other hand to easier opening and closing of the loading flap unit according to the invention.

In one embodiment of the vehicle loading flap unit according to the invention, a retaining foot, to which the spring section is attached, projects on the inside of the outer flap. The retaining foot is an extension which extends from the inside of the outer flap in the closing direction of the outer flap. The push-slide button can simply be slipped over it, which is advantageous, for example, when assembling the parts. In addition, the retaining foot increases the stability of the push-slide button and serves as a linear bearing for the push-slide button.

In a further embodiment, the retaining foot extends into the interior of the spring section. This further increases the stability of the push-slide button.

The spring section is preferably fastened on the flap side at its flap-side end via a retaining ring surrounding it, in particular via a locking connection provided on the retaining ring.

The flap-side end of the push-slide button is z. B. L-shaped. The retaining ring can be placed on the horizontally extending part of the L-shaped end. The latching connection provided on the retaining ring can, for example, comprise webs which run in the direction of the outer flap and have a recess. With extensions or bulges complementary to the recesses, which are formed directly or indirectly on the inside of the outer loading flap, the retaining ring and thus the push-slide button can be attached directly or indirectly to the outer flap.

The retaining foot preferably serves as a linear bearing for the spring section and the spring section slides along the outside of the retaining foot during compression and rebound. As a result, lateral deformations and bending of the push slide button, as they are for Example can occur when sliding a vehicle part along the sliding section, prevented and transferred into a predominantly axial deformation of the push-slide button.

In particular, the holding foot is hollow and has an end face that is open to the sliding section, from which a guide extension on the sliding section protrudes into the interior of the holding foot and rests against the latter on the inside. This increases the stability of the push-slide button against forces acting laterally to the longitudinal axis, which are also more efficiently transformed into a predominantly axial deformation of the push-button slide.

According to one aspect, a rib-like guide web protruding from it is provided on the inside of the outer flap and extends in the longitudinal direction of the flap from its axis to the push-slide button. The sliding section forms a continuation of the upper side of the guide web. When opening the outer flap and the opening of the inner flap initiated thereby, the inner flap slides with a free edge section along the sliding section and along the guide web into its open position. Conversely, the inner flap slides with its free edge section when the outer flap is closed along the guide web to the push-slide button.

The inner flap is pushed into its closed position by the push-slide button when the outer flap is completely closed.

If a locking device is provided on the inner flap, the push-slide button and guide bar together form an unlocking and guiding device which, on the one hand, unlock and guide the inner flap into its open position and, on the other, guide it into its closed position.

The sliding section preferably has a wedge-shaped cross-sectional geometry with an end-face contact surface which, starting from the height of the guide web, extends further away from the inside of the flap with increasing lateral distance from the guide web. The wedge-shaped cross-sectional geometry of the sliding section and the inclined contact surface allow the inner flap to slide and push into its closed / locked position. With an edge of the contact surface furthest away from the outer flap, the locking device of the inner flap is pushed away to the side, as a result of which the inner flap is unlocked.

According to a further aspect, the guide web is a unit which is separate from the flap and is fastened to the flap and merges laterally in one piece into a base on which the retaining foot protruding into the interior of the spring section is formed. This allows the guide bar to be easily exchanged. In another embodiment, it is also conceivable that the guide web is integrally formed on the outer flap.

One embodiment provides that the sliding section and the spring section form a finished, preassembled unit. The sliding portion and the spring portion are most stressed when opening and closing the shutter unit. It is therefore sensible to provide the sliding and spring sections as a separate unit, as they can be easily replaced if necessary.

Another embodiment provides that a sleeve is formed on the sliding section, which engages on the outside of the holding foot, surrounds it and is linearly guided on the holding foot. The spring section is attached to the sliding section via the sleeve. The sleeve also contributes to the stability of the push-slide button.

In another embodiment, the retaining foot can also be attached directly to the inside of the outer loading flap 12 be molded, glued, screwed, welded or the like.

3 shows a sectional view through the push-slide button 100 and the guide bar 16 .

The slide push button 100 has an elastic spring portion 102 and a sliding section that is harder and less elastic than the spring section 104 on, the one on one face of the push slide button 100 is provided.

The spring section 102 and the sliding section 104 are two separate components that form a finished, pre-assembled unit.

The spring section 102 is made of a different, in particular more elastic plastic than the sliding section 104 made of a harder plastic. For example, the spring section 102 be designed as a rubber buffer, in particular as a rubber bellows.

Due to the inherent elasticity of the spring section 102 is the sliding section 104 frictionally in the spring section 102 appropriate. Optionally, the sliding section 104 in another way (e.g. gluing) in the spring section 102 to be appropriate.

At a flap-side end of the spring section 102 is a the spring section 102 surrounding retaining ring 106 attached over which the Push slide button 100 at the base 18th of the guide bar 16 is appropriate.

In particular, the flap-side end of the spring section 102 is L-shaped and the retaining ring 106 is placed on the horizontal section of the L-shaped end.

In the embodiment shown here is the push-slide button 100 via a locking connection with the guide bar 16 connected. These are on the retaining ring 106 Bridges 108 integrally formed, which have a recess, which are complementary thereto formed extensions or bulges 110 inside the guide bar 16 can be locked.

The slide push button 100 can also be used directly with the outer flap 12 be connected.

The spring section 102 of the push-slide button 100 is over the retaining foot 34 inverted, with the retaining foot 34 as a linear bearing for the spring section 102 serves on which the spring section 102 slides along the outside during compression and rebound.

The guide bar 16 with the base 18th as well as the retaining foot 34 are hollow.

The holding foot 34 forms a kind of guide channel that leads to the base 18th is open and one to the sliding section 104 has an open front.

To stabilize the axial movement when the push-slide button springs in and out 100 is on the sliding section 104 a guide extension 112 formed, which is in the interior of the retaining foot 34 protrudes and rests against this on the inside.

On the sliding section 104 is a sleeve 114 molded on the outside of the retaining foot 34 attacks, surrounds him and on the holding foot 34 is linear.

The sliding section 104 has a wedge shape with a frontal contact surface 116 that differ from the height of the guide bar 16 starting with increasing lateral distance from the guide bar 16 further from the inside of the outer flap 12 extends away.

The spring section 102 matches the wedge shape of the sliding section 104 educated.

Through the contact area 116 of the push-slide button 100 becomes the top 32 of the guide bar 16 continued.

The top 32 of the guide bar 16 and the contact area 116 of the push-slide button 100 together form guide surfaces on which the inner flap 14th slides along.

The following describes the opening and closing / locking mechanism of the tailgate unit 10 described. The starting point is a closed or locked state of the loading flap unit 10 assumed as he was in 1 is shown.

The push-slide button is in this state 100 between the outer flap 12 and the inner flap 14th compressed or compressed and presses against the inner flap 14th . The spring-loaded push-slide button 100 acts on the outer flap in its opening direction and the inner flap in its closing direction.

When unlocking the outer flap 12 , by for example a push-push mechanism, becomes the outer flap 12 pressed in the closing direction by a pressure applied by a user, whereby the push-slide button 100 is further compressed.

Due to the resilient property and inherent rigidity of the push-slide button 100 the push-slide button is extended 100 after unlocking the outer flap 12 to its normal state, pushing the outer flap 12 something in their opening direction.

With further opening of the outer flap 12 the push-slide button slides 100 with the contact surface 116 of the sliding section 104 on the locking element 26th and moves it from the inner flap against its direction of biasing 14th path.

Once the inner flap 14th no longer from the locking element 26th is locked, it folds due to its bias about its fastening axis in the direction of the outer flap 12 on. The locking element 26th then returns to its original position.

The inner flap slides during opening 14th with its free edge section, which is preferably opposite the fastening edge section 20th the inner flap 14th first along the contact surface 116 of the sliding section 104 of the push-slide button 100 and with further opening of the outer flap 12 along the top 32 of the rib-like guide web 16 in their fully open end position.

When closing the outer flap 12 is the user on the outer flap 12 applied pressure via the push slide button 100 on the inner flap 14th transferred, creating the inner flap 14th against their bias in the direction of the charging port 15th is closed around its fastening axis. The inner flap slides 14th with their free edge portion first along the top 32 of the rib-like guide web 16 to the contact surface 116 of the sliding section 104 of the pressure control button 100 and then along the contact surface 116 of the sliding section 104 of the push-slide button 100 .

From a certain folded position of the inner flap 14th touches the free edge portion of the inner flap 14th the locking element 26th the locking device 24 .

With further closure the locking element 26th against its bias increasingly from the inner flap 14th pushed away.

While locking the outer flap 12 by means of z. B. a push-push mechanism is the outer flap 12 overpressed, the inner flap 14th is pushed into its fully closed position. The locking element moves in this position 26th due to its pretension back to its original position and thereby locks the inner flap 14th .

In a preferred embodiment there is no locking device 24 intended. By locking the outer door 12 also the inner flap 14th "locked" in their closed end position.
