Background technology

Known for a long time in the prior art by the method for type of the present invention.At this, be equipped with door latch, the arrangements for automotive doors of lock pawl and door lock assembly mechanism or trunk lid blocking device and be furnished with tension servicing unit for door latch.Described tension servicing unit is used for car door or trunk lid etc. to insert main card lock status or blocking from pre-kayser state or intermediateness as servicing unit, to make the more comfortable and reliable in function of closing process thus.

A kind of method for opening and closing trunk lid according to type of the present invention is such as described by DE1994454A1.

DE102009012602A1 also illustrates a kind of blocking device for motor vehicle trunk lid, and it opens and closes according to the method by type of the present invention.

Especially for the motor vehicle with larger row boot cover and car door, need to expend larger power because quality and inertia are comparatively large when opening and closing.This causes by needing the corresponding fastening devices (hinge, lock) of having outstanding performance for luggage-boot lid and car door overcome.Use known tension servicing unit at this, they alleviate difficulty by " tension " locking device and/or by the device that unlocks in time.The standard unlocked in time can be such as: extracted, from outside locking/unlocking etc. from igniting lockhole by firing key.

Also need to consider, motor vehicle and its luggage-boot lid and car door are structurally designed to, and make them also can promote vehicle body rigidity related to thisly.This is particularly useful for the situation of running at high speed because by the pressure ratio between the inner space that formed thus and external environment condition especially by car door to external pressure.Therefore, need to have corresponding power transmission between vehicle body and luggage-boot lid or car door and connect, this is structurally reached by a large amount of fastening devicess.

But, on the one hand " open and close car door/luggage-boot lid time there is lightness " and another aspect " higher vehicle body rigidity " and " avoiding wind noise " requirement cause producing afoul structure design.Half-way house can only be realized in the prior art so far in these require.

The present invention gets down to this and attempts to solve this object conflict better.

Summary of the invention

Technical problem to be solved by this invention is, improves the method for type of the present invention like this, thus reduces above-mentioned purpose conflict.

This technical problem is solved by a kind of method for blocking device closedown or the car door opened on body of a motor car or trunk lid etc. by having at least one latching member and cooperation latching member by the present invention, wherein, described blocking device can electromechanical ground locking or open, and described two latching members are by auxiliary equipment (tension servicing unit) relative motion like this, make in order to closed door or trunk lid etc., blocking is entered from car door or trunk lid and vehicle body intermediateness separated by a distance, in described blocking, car door or trunk lid and vehicle body are separated by the distance less than the distance in intermediateness, and in order to open car door or trunk lid etc., intermediateness is returned from blocking.Specify by the present invention, in at least one limiting value of certain status data reached or through environmental data and/or automobile, at least one element of the described blocking device of such control, make the such relative motion of latching member, thus make car door or trunk lid etc. enter at least another blocking from described blocking, in another blocking described, car door or trunk lid and vehicle body are separated by the distance less than the distance in the blocking first mentioned.

Important Thought of the present invention is the lock-out state dynamically affecting blocking device.

Status data as automobile especially can use the speed of a motor vehicle or such as by the motor vehicle load of proper sensors measurement device (longitudinally, laterally and/or vertically power).

Therefore usually also there will be the more Larger Dynamic load for automobile when the speed of a motor vehicle is higher, this requires that vehicle body rigidity improves.In addition, when speed is higher, wind noise also increases, and therefore looks it is Worth Expecting at this to car door further " sound insulation ".

But also may there is the dynamic load of the raising for automobile when the speed of a motor vehicle is lower, such as, in region, roadside or on poor highway.

Be such as weather condition (wind, rain) as environmental data, they being comprised is significant in the process.If such as drive trip when wind is larger, even if then the speed of a motor vehicle is lower also can feel that wind noise is unhappy.

Achieve improvement in all cases in the following manner according to method of the present invention, that is, control tension servicing unit according to this Data Dynamic and therefore make the lock-out state of automobile adaptive from different situations.

But this " enhancing " locking should not increase the difficulty that next passenger gets off.Therefore according to one expansion design code of the present invention, in at least one limiting value of certain status data reached or through environmental data and/or automobile, at least one element of the described blocking device of such control, make the such relative motion of latching member, thus make car door or trunk lid etc. get back at least one car door or trunk lid and vehicle body from described at least another blocking to be separated by heavily again than the blocking of distance larger when described at least another blocking.

Therefore, such as usually occurring in the long-distance of fair speed or highway driving, at least one element of blocking device should enter another blocking, and should enter the first blocking (main card lock status) again when the city that following speed is obviously lower travels.Car door or trunk lid etc. can be opened easily again by main card lock status.

Already proved advantageous particularly and suitable, to have reached or through certain speed of a motor vehicle, at least another blocking or shift out from described at least another blocking described in described car door or trunk lid etc. enter.Speed is extremely important for vehicle condition data and the parameter that can measure easily.

According to the particularly advantageous design code of the one of inventive concept, described blocking is supported by mechanical latch state.This advantage had is that, when supply of electric power is malfunctioning, car door or luggage-boot lid etc. reliably keep locking in all cases.

Therefore, tension servicing unit is preferably designed for, and makes car door or luggage-boot lid etc. to close with the rank of multiple definition and again to open.Substantially the tension servicing unit of the classification kayser of machinery support continues when power failure reliably to cut out.Current needs also than can the infinitely variable method of alternative consideration little, in this infinitely variable method, (adding) position of car door or luggage-boot lid etc. is only kept by tension servicing unit and therefore must be carried out being energized and electric power monitoring in long period section.

According to the expedients of inventive concept, at least one element dynamically affecting the blocking device of the lock-out state of blocking device can be described auxiliary equipment (tension servicing unit) itself, independent actuator or lock bow.

If such as use tension servicing unit, then this advantage had is, can apply the very firm blocking device element natively used.

When using independent actuator, the control of tension servicing unit can keep simpler for this reason.Preferably use linear regulation element as actuator, it is firm and reliable equally.

When using lock bow, can the constant tension servicing unit of using function.Lock bow is designed at this, makes it can motorized adjustment and therefore draw closer to vehicle body by car door or luggage-boot lid etc.

The present invention also relates to a kind of automobile locking part for performing according to the inventive method.Described latching member has at least one for engaging the door latch of lock bow, wherein, described door latch can by controlled servicing unit around axle revolution and thus from entering with the corresponding primary importance of intermediateness (pre-kayser state) and the corresponding another location of blocking (main card lock status).

According to the present invention, described door latch can enter at least another location corresponding to another blocking from described another location (main card lock status) by least one element of described latching member, in this another blocking, need the car door of closedown or luggage-boot lid etc. less or tightr with the distance of vehicle body.

Effectively contacting first between latching member and cooperation latching member produces in the closedown such as car door or luggage-boot lid and lock bow is fixed on the time point in so-called latched position in advance by the door latch of latching member.At this time point, control tension servicing unit like this, make it effectively can contact with door latch and door latch be inserted at least two other positions.At this, first another location is equivalent to known main card lock status, and other positions all are equivalent to the blocking added, and therefore can be performed according to method of the present invention by latching member.

Proved practical especially at this, described latching member has lock pawl, and described lock pawl enters at least three latched position by described door latch.

Lock pawl has kayser face, and it can be bearing on the cooperation kayser face of door latch.Therefore, door latch can at least " kayser enters " be equivalent in the state of intermediateness (pre-kayser state), blocking (main card lock status) and another blocking.If in door latch " kayser enters " a certain state, also can stably keep this state when not being energized.Most of actual conditions can be covered by described three kinds of states, wherein can certainly consider the latched position more than three kinds.

Already confirmed suitable, the axis of rotation with having at least one metal strap portions respectively around door latch and/or lock pawl reels.

This metal tape has the performance of Ohmic resistance and is preferably made up of high ohmic metal.By the respective episode pantograph (it is by pretightning force contacting metal band) be made of metal, can with potentiometric form by carrying out location recognition on the part easily along with the resistance rolled or deployed condition changes.Because position data exists redundantly in this way, so the wrong identification of being undertaken by appropriate device or error correction are also admissible.Differently also can consider with the form of implementation of redundancy, only this metal tape is set on one of above-mentioned parts.

The technical scheme utilizing described metal tape to carry out detecting also is relative to the advantage of the known solution with Multi-stage minitype switch, and metal tape can export and therefore can detect outside Polluted area from Polluted area.This contributes to the vulnerable to pollution of reduction system.

At least one element of latching member can be auxiliary equipment itself or independent actuator as already mentioned worthily.

Finally, the invention still further relates to a kind of automobile, it has at least one this latching member.This automobile can according to by method locking of the present invention or open, and this contributes to driving safety and driving comfort.

Accompanying drawing illustrates that car door 3 is in blocking (main card lock status), wherein strains servicing unit and car door 3 has been inserted shown main card lock status from intermediateness (pre-kayser state).In a state in which, car door 3 and B post 5 standoff distance a2.With this distance a2, door sealing part 6 is pressed against on B post 5 like this, makes at least that car door 3 is hermetically and abut on B post 5 with can not sending rattle when medium speed.

When fair speed, car door 3 to further a segment distance to vehicle body or B post 5 by tie unit, and the distance a3 that therefore car door 3 and B post are formed is less than distance a2.

Fig. 3 more puts it briefly clear the method.

That x-axis shows is car door 3 or luggage-boot lid 4 and the distance a of the vehicle body of automobile K, and in y-axis writing speed v.

Under the inactive state of automobile K (v=v0), after manually closing entrance door 3/ luggage-boot lid 4, first lock and lock bow mediate state (pre-kayser state), wherein car door 3/ trunk lid 4 and vehicle body standoff distance a1 respectively.By this so-called pre-kayser state, activate be respectively the component of lock 1 or 2 tension servicing unit and such as pull car door 3 further near B post 5 to enter blocking (main card lock status), in this condition, car door 3 and B post 5 standoff distance a2.

What can use in the method according to the invention will be described according to Fig. 4 according to after lock component of the present invention.

To reach or when certain speed v1 (can be such as 120km/h), tie unit activate further and pull car door 3 from the first blocking (a2) closer to B post 5 to enter the second blocking (a3), wherein, car door 3 is less than distance a2 again with the distance a3 of B post 5.

In addition, can also arrange other rank, it is represented by another speed v 2 and corresponding distance a4.

To reduce distance a same meaningfully again along with the speed of a motor vehicle v reduced increases distance a step by step with the increase along with speed v.

Illustrate for understanding the very important lock of the present invention (such as lock 1) component and setting forth in its functional interaction according to Fig. 4 now:

Therefore, the tie unit 10 that the lock 1 (latch fitting) being designed to servo lock has door latch 11, lock pawl 12 according to known way and can engage with door latch 11.Door latch 11 is made up of matrix 110, and described matrix can rotate around axis of rotation D2.The recess 111 of elongated hole-shape is housed in this external matrix 110, and described recess 111 is for holding lock bow 7 (the cooperation latch fitting of lock 1).

Door latch 11 also has the contact surface 114 for detection type contact microswitch M1.

In addition, matrix 110 forms hook arm 112.Described hook arm 112 forms the first kayser face 115 and the second kayser face 116, and their function also will describe afterwards.

Lock pawl 12 can rotate around axis of rotation D3 and have at the first cantilever 120 place for detection type contact microswitch M2 contact surface 122 and be equipped with the second cantilever 121 coordinating kayser face 124 and 125.Described cooperation kayser face 124,125 is with the mode that will describe and already mentioned kayser face 115,116 acting in conjunction.

In addition, hook arm 112 has the contact surface 113 towards lock pawl 12, and described contact surface 113 effectively can contact with the contact surface 123 of lock pawl 12.

Tie unit 10 be electrically controlled in the mode be not shown specifically and electromechanical move.It has the matrix 100 and rotary hook 101 that can rotate around axis of rotation D1, and described rotary hook 101 is connected with matrix 100 pivotally by axis of rotation D4.

Car door 3 is not closed to yet and makes lock bow 7 can by door latch 11 " catching " in fig .4.Herein in position R0, in this position, there is not kayser and door latch 11 and lock pawl 12 rotate freely each other by contact surface 113 and 123 in door latch 11 and lock pawl 12.

Tie unit 10 does not also have function or the connection with door latch 11 in this position.

If car door 1 continues to close (see Fig. 4 b), then lock bow 7 to be pressed against on the downside of recess 111 and make thus door latch 11 along clockwise direction (see arrow) rotate.This motion is until lock pawl 12 coordinates kayser face 124 to snap in the kayser face 115 of door latch 11 with it thus till entering the first latched position R1 (pre-kayser state).

In this latched position R1, lock bow 7 has been captured in the recess 111 of door latch 11, and can not by mistake open car door 3 again, because prevent door latch 11 revolution in the counterclockwise direction by lock pawl 12.

Shown latched position R1 makes car door 3 and B post standoff distance a1 (also see Fig. 2 and Fig. 3).

Along with door latch 11 and lock pawl 12 rotate in this position, microswitch M1 and M2 also by compressed to the acting in conjunction of contact surface 114 or 122 and tie unit 10 by be not shown specifically signalling technique on connection obtain corresponding signal.Thus, the matrix 100 of tie unit 10 rotates (see arrow) and rotary hook 101 engages with the hook arm 112 of door latch 11 thus in the counterclockwise direction.

The tie unit 10 activated continues to rotate in the counterclockwise direction according to Fig. 4 c and therefore door latch 11 also continues to be rotated in a clockwise direction, until door latch 11 and lock pawl 12 enter the second latched position R2.In the second latched position R2, the kayser face 116 of door latch 11 is bearing on the cooperation kayser face 124 of lock pawl 12.

Thus, lock bow 7 is also continued to further, thus forms the distance a2 (see Fig. 3) of car door 3 and B post 5.

Correspondingly, microswitch M1, M2 on the contact surface 114 or 122 being designed to chute-like altered contact position by power monitoring equipment (not shown) record.

When the speed v that Fig. 4 d is presented at automobile K increases, how tie unit 10 continues to rotate in the counterclockwise direction according to the present invention, thus forms the 3rd latched position R3 being equivalent to distance a3 in Fig. 3.

In latched position R3, the kayser face 116 of door latch 11 effectively contacts mutually with the cooperation kayser face 125 of lock pawl 12.

This realizes in the following manner, namely, first by tie unit 10, door latch 11 (the latched position R2 from Fig. 4 c) is continued to be rotated in a clockwise direction always, until kayser face 116 and 124 is lifted away from each other and therefore makes lock pawl 12 be rotated in a clockwise direction to latched position R3 without resistance.

Except latched position R1 to R3 also can consider other latched position as required.

Also can consider replace latched position R2 and R3 and infinitely realize this position.

But the precondition done like this is the lasting energising of tie unit 10, door latch 11 must remain in corresponding position by it.

The advantage of shown latched position R1 to R3 is, each latched position (such as when having a power failure) under non-"on" position also keeps stable.

How the last speed v being presented at following automobile K is in figure 4e converted back to the second latched position R2 from the 3rd latched position R3 when declining again.

Do not carried out with noticing by driver as far as possible to make this process, tie unit 10 rotates (see dotted arrow) first in the counterclockwise direction slightly, thus kayser face 116 and 125 is slightly lifted each other be separated, and lock pawl 12 can back move in the counterclockwise direction equally (see dotted arrow) until kayser face 116 and 124 superimposed aligning again.At this moment tie unit 10 by rotation (see solid arrow) along clockwise direction again by door latch 11 " putting " on lock pawl 12.

In figure 4e, replace microswitch M1, M2 and show metal strip S 1, S2, they reel around axis of rotation D2 or D3 of door latch 11 or lock pawl 12 respectively.

By metal strip S 1, S2, the detection of the position of rotation of door latch 11 or lock pawl 12 can be realized by probe AB1, AB2 according to potentiometric kind.At this, probe AB1, AB2 can be arranged in the outside of lock 1, i.e. the outside of Polluted area.

It is also conceivable to as alternative form of implementation, the tension rotary hook 101 of auxiliary equipment 10 or the hook arm 112 of door latch 11 are designed to multi-stag, be namely equipped with the second hook 102 or 117 (only represented by dashed line in fig .4).Thus, such as hook 117 can in order to realize with latched position R3 (see Fig. 4 d) similar latched position and with rotary hook 101 kayser (not shown), wherein in this case, tie unit 10 needs to realize this latched position less distance of moving.

Finally also show another kind of form of implementation of the present invention in Figure 5, wherein, only have door latch 11 part visible.With the independent actuator that Fig. 4 a to Fig. 4 e is linear regulation element 8 unlike the form of being provided with.Linear regulation element 8 can act on kayser face 115 like this, and door latch 11 is rotated in the position similar with latched position R3.At this, linear regulation element 8 is also designed to keep stable when not being energized, and this can realize preferably by corresponding reducer in this case.Also can specify as alternative, use can be automatically controlled latch hook 7', it moves like this when controlled, makes it apply pulling force along direction Z and pull car door or luggage-boot lid etc. with closer to vehicle body thus.

The present invention is not limited to above-described embodiment.Described embodiment is only for draw outlines of core concept of the present invention.The present invention also can comprise the content being different from previous embodiment or knowing example in its protection domain.At this, the present invention especially also can have the feature of being closed by every groups of individual features of each claim.
