Description

本発明は、一般的に、特に歩行者との衝突による衝撃または機械的な応力の一部を緩和することを可能にする、自動車のボンネット用ロック装置に関する。
より詳細には、本発明は、第１部と第２部とを含んでなり、上記第１部と第２部の一方はボンネットに取り付けられ、他方は車体の部材に取り付けられ、ロック装置の上記第１部と第２部との、第１方向に沿った相互の接近運動によって、上記ボンネットが上記車体の部材に選択的に取り付けられ、上記第１部は、主として受け座を有し、上記受け座は、少なくとも１つのプレートと受け座ロッドを有する、自動車のボンネット用ロック装置に関する。 The present invention relates generally to a locking device for an automobile bonnet that makes it possible to relieve some of the impact or mechanical stress, especially due to a collision with a pedestrian.
More specifically, the present invention includes a first part and a second part, one of the first part and the second part being attached to a bonnet, the other being attached to a member of a vehicle body, The bonnet is selectively attached to a member of the vehicle body by the close movement of the first part and the second part along the first direction, and the first part mainly has a receiving seat, The receiving seat relates to an automobile bonnet locking device having at least one plate and a receiving rod.

自動車と歩行者との正面衝突の際には、一般に、歩行者の頭部が自動車の車体と衝突するようになり、主にボンネット、窓枠またはフロントガラスに接触する。
このため、多くの自動車製造者は、自動車に衝突された歩行者が受ける衝撃を緩和する、沢山の解決策を開発してきており、このような衝撃は、例えばボンネットのロック装置によって緩和することが可能である。
上記の「技術分野」で定義した形式のロック装置は、このような緩和を可能にし、例えばトヨタ自動車ＫＫの日本国特許文献ＪＰ ２００２０１９６４１に記載されている。
この固定の形態は、歩行者との衝突の際または機械的な過負荷が大きいときに、台板の移動を可能にする３点固定によって実現される。この固定の形態は、衝突の際に、ロック装置の第２部上の受け座から伝達される機械的なエネルギの一部を吸収するための、機械的なヒューズを構成する。
従来技術のこのロック装置は、衝撃吸収機能を有するが、技術的な多くの問題を呈する。例えば、台板と車体の部材との間に存在する変化する摩擦力のために、衝突の際のエネルギ吸収量を正確に調整することはできない。さらに、衝撃の吸収を可能にする移動の大きさは極めて小範囲に限定される。
また、衝突のエネルギの吸収の一部は、車体に取り付けられた弾性支持部材の変形によることを考えると、衝撃が大きいと支持部材が永久変形し、極めて困難な修理が必要になるというリスクがある。
日本国特許文献ＪＰ ２００２０１９６４１ In a frontal collision between an automobile and a pedestrian, the head of the pedestrian generally collides with the body of the automobile, and mainly comes into contact with the hood, window frame or windshield.
For this reason, many car manufacturers have developed a number of solutions to mitigate the impact of pedestrians hit by a car, and such shocks can be mitigated by, for example, a bonnet locking device. Is possible.
The locking device of the type defined in the above “technical field” enables such relaxation, and is described, for example, in Japanese Patent Document JP 20020199641 of Toyota Motor Corporation KK.
This fixed form is realized by three-point fixing that enables movement of the base plate in the event of a collision with a pedestrian or when a mechanical overload is large. This fixed configuration constitutes a mechanical fuse for absorbing part of the mechanical energy transmitted from the seat on the second part of the locking device in the event of a collision.
This prior art locking device has a shock absorbing function but presents many technical problems. For example, due to the changing frictional force that exists between the base plate and the body member, the amount of energy absorption at the time of collision cannot be adjusted accurately. Furthermore, the magnitude of movement that allows shock absorption is limited to a very small range.
Also, considering that part of the energy absorption of the collision is due to deformation of the elastic support member attached to the vehicle body, there is a risk that the support member will be permanently deformed if an impact is large, and that extremely difficult repairs will be required. is there.

先に述べたように、本発明は、２部から構成されたロック装置に関する。図１に示す実施例においては、第１部２は、固定ベース２２を介してボンネット１に固定され、第２部３は、自動車の車体４に固定される。
ロック装置の第１部２と、第２部３は、ボンネット１を閉めるために、第１方向５に沿って、互いに選択的に接近させることができ、あるいは、ボンネット１を開ける動作においては、第１方向とは逆の、第２方向１４に沿って、互いに選択的に遠ざけることができる。 As described above, the present invention relates to a locking device composed of two parts. In the embodiment shown in FIG. 1, the first part 2 is fixed to the bonnet 1 via the fixed base 22, and the second part 3 is fixed to the vehicle body 4 of the automobile.
The first part 2 and the second part 3 of the locking device can be selectively approached to each other along the first direction 5 in order to close the bonnet 1, or in the operation of opening the bonnet 1, They can be selectively moved away from each other along the second direction 14, which is opposite to the first direction.

ボンネット１が閉められているときには、ロック装置は閉鎖形態にあり、ボンネット１が開かれているときにはロック装置は開放形態にある。図１においては、ロック装置は開放形態にあり、ロック装置の第１部２は、第２部３から僅かに遠ざけられている。受け座６はボンネット１に取り付けられており、第１プレート７と第２プレート８を有する。第１プレート７と第２プレート８は、第１方向５に概ね平行であり、また第１プレート７と第２プレート８は互いに概ね平行である。第１プレート７と第２プレート８は、受け座６の各側に横方向に配置され、第１プレート７と第２プレート８の、ボンネット１との組み立てを可能にする、固定ベース２２を介して互いに連結される。固定ベース２２は、ボンネット１へ従来の任意の手段、特に溶接またはボルト止めによって固定される。第１プレート７と第２プレート８の間隔は、それらが、ボンネット１が閉じられているときに、ロック装置の第２部３の両側上を覆うように設けられる。第１プレート７に第１細長開口１０が、第２プレート８に第２細長開口１５が設けられる。第１細長開口１０と第２細長開口１５は互いに平行で、第１方向５と平行な向きに向けられる。第１細長開口１０と第２細長開口１５の中へ受け座ロッド９が挿入され、第１プレート７と第２プレート８と第１方向５に概ね直行して位置づけられる。 When the bonnet 1 is closed, the locking device is in the closed configuration, and when the bonnet 1 is opened, the locking device is in the open configuration. In FIG. 1, the locking device is in an open configuration, and the first part 2 of the locking device is slightly away from the second part 3. The receiving seat 6 is attached to the bonnet 1 and has a first plate 7 and a second plate 8. The first plate 7 and the second plate 8 is generally planar row in a first direction 5, also the first plate 7 and the second plate 8 is generally parallel to each other. The first plate 7 and the second plate 8 are arranged laterally on each side of the receiving seat 6 via a fixed base 22 that allows the assembly of the first plate 7 and the second plate 8 with the bonnet 1. Connected to each other. The fixing base 22 is fixed to the bonnet 1 by any conventional means, in particular by welding or bolting. The distance between the first plate 7 and the second plate 8 is provided so that they cover both sides of the second part 3 of the locking device when the bonnet 1 is closed. A first elongated opening 10 is provided in the first plate 7, and a second elongated opening 15 is provided in the second plate 8. The first elongated opening 10 and the second elongated opening 15 are parallel to each other and oriented in a direction parallel to the first direction 5. The receiving rod 9 is inserted into the first elongate opening 10 and the second elongate opening 15, and is positioned substantially perpendicular to the first plate 7 and the second plate 8 in the first direction 5.

受け座ロッド９は、ロック装置の第２部３に作られた、受け座ロッド通過開口２３に沿って移行するように設けられる。ボンネット１が閉鎖位置にあるときに、受け座ロッド９は、受け座ロッド通過開口２３の底部に位置づけられ、全体に受け座ロッド通過開口２３の端部に支持されるようになる。ロック装置の第２部３には、簡明化のために図１には図示されていない、受け座ロッド９の、従来の保持装置が設けられている。例えば、受け座ロッド９の従来の保持装置は、その少なくとも一部が、受け座ロッド通過開口２３の中における受け座ロッド９の、第２方向１４に沿った移動を妨げる、滑動または回転可能な舌状片から構成することができる。このような従来の保持装置は、ロック装置が閉鎖形態にあるときには、受け座ロッド９の、受け座ロッド通過開口２３の底部への保持を可能にし、ロック装置が閉鎖形態から開放形態へ移行するときには、受け座ロッド９の開放を可能にするものでなければならない。 The receiving rod 9 is provided so as to move along the receiving rod passage opening 23 made in the second part 3 of the locking device. When the bonnet 1 is in the closed position, the receiving rod 9 is positioned at the bottom of the receiving rod passage opening 23 and is supported by the end of the receiving rod passage opening 23 as a whole. The second part 3 of the locking device is provided with a conventional holding device for the receiving rod 9 which is not shown in FIG. 1 for the sake of simplicity. For example, the conventional holding device for the receiving rod 9 is slidable or rotatable, at least a part of which prevents movement of the receiving rod 9 in the receiving rod passage opening 23 along the second direction 14. It can consist of tongues. Such a conventional holding device makes it possible to hold the receiving rod 9 at the bottom of the receiving rod passage opening 23 when the locking device is in the closed configuration, and the locking device shifts from the closed configuration to the open configuration. Sometimes it must be possible to open the receiving rod 9.

第１プレート７に、安全フック１３が可動に取り付けられる。安全フック１３は、第１プレート７に直交する軸の周りに回動可能に取り付けることが望ましい。安全止め金具２５が車体４の部材に取り付けられる。ロック装置の開放形態においては、受け座ロッド９の保持装置によって受け座ロッド通過開口２３の底部に保持されていない受け座６は、第２方向１４に沿って自由に移動できる。従って、ロック装置の第１部２は、ロック装置の第２部３から自由に遠ざけることができる。この開放形態において、ボンネット１に取り付けられた安全フック１３の開口部が、車体４の部材に取り付けられた安全止め金具２５に支持されるようになり、第１部２の第２部３に対する間隔の大きさが制限され、ボンネット１が安全な開放位置を越えて無意識に開放される危険が回避される。
安全フック１３は、該安全フック１３が安全止め金具２５に支持されて係合される安全角度位置と、安全フック１３の安全止め金具２５との係合が解除されるように軸の周りに回動された安全解除角度位置との間を可動である。ロック装置が安全な開放位置にあって、安全フック１３が安全止め金具２５に支持されて係合されているときに、安全フック１３を安全解除角度位置へ開放レバー２４を用いて手動で移動させることができ、ボンネット１を安全な開放位置を越えて開放することができる。
望ましくは、安全フック１３は、安全角度位置内へ強制的に引き戻す第１トルクを受けるようにされる。安全フック１３に取り付けられた開放レバー２４が、安全角度位置から安全解除角度位置へ手動で回動させるための、第１トルクと逆向きの第２トルクを、安全フック１３に作用させることを可能にする。 A safety hook 13 is movably attached to the first plate 7. The safety hook 13 is preferably attached so as to be rotatable around an axis orthogonal to the first plate 7. A safety stopper 25 is attached to the member of the vehicle body 4. In the open configuration of the locking device, the receiving seat 6 that is not held at the bottom of the receiving rod passage opening 23 by the holding device of the receiving rod 9 can move freely along the second direction 14. Accordingly, the first part 2 of the locking device can be freely moved away from the second part 3 of the locking device. In this open configuration, the opening of the safety hook 13 attached to the bonnet 1 is supported by the safety metal fitting 25 attached to the member of the vehicle body 4, and the distance between the first part 2 and the second part 3 is increased. And the risk that the bonnet 1 is unconsciously opened beyond the safe opening position is avoided.
Safety hook 13 times around the axis so that the safety angular position in which the safety hook 13 is engaged is supported by the safety stop member 25, the engagement between the safety stop member 25 of the safety hook 13 is released It is movable between the moved safety release angle position. When the locking device is in the safe open position and the safety hook 13 is supported and engaged by the safety catch 25 , the safety hook 13 is manually moved to the safe release angle position using the release lever 24 . The bonnet 1 can be opened beyond the safe opening position.
Desirably, the safety hook 13 is subjected to a first torque that is forcibly pulled back into the safe angular position. The release lever 24 attached to the safety hook 13 can act on the safety hook 13 with a second torque opposite to the first torque for manually rotating from the safety angle position to the safety release angle position. To.

It has a width L. Therefore, seat rods 9, first, it is impossible along the second elongated opening 10, 15 free to slide in the second direction 14, the first of the first, second elongated openings 10, 15, It remains in the original position fitted in the second parts 11 , 16 .
In this embodiment, the first and second elongated openings 10 and 15 of the first and second plates 7 and 8 of the receiving seat 6 are geometrically similar to each other. The first and second portions 11 and 16 of the first and second elongated openings 10 and 15 have an arc shape whose diameter is substantially equal to the diameter of the cylindrical receiving rod 9.
The third and fourth portions 12 and 17 of the first and second elongated openings 10 and 15 have a width L smaller than the diameter of the receiving rod 9 and form a groove whose side surfaces are substantially parallel to each other.

歩行者に衝突後を示す図４は、受け座ロッド９が末端に位置する、本発明による受け座６を示す。この末端位置においては、受け座ロッド９は第１、第２細長開口１０、１５の中を移動させられて、固定ベース２２及びボンネット１に近い第１、第２細長開口１０、１５の端部における、第１、第２細長開口１０、１５の第３、第４部分１２、１７の中に位置する。 FIG. 4, which shows after a collision with a pedestrian, shows a receiving seat 6 according to the invention in which a receiving rod 9 is located at the end. In this end position, seat rod 9 first, and moved through the second elongated opening 10, 15, first near the fixing base 22 and the bonnet 1, the end portion of the second elongated opening 10, 15 In the third and fourth portions 12 and 17 of the first and second elongated openings 10 and 15 .

歩行者からの衝撃の影響を受けると、ボンネット１は第１方向５に沿って落ち込む傾向を有する。受け座ロッド９は、車体４の部材に取り付けられたロック装置の第２部３に支持されており、第２方向１４に対向する抵抗力が、受け座ロッド通過開口２３の底部に支持された受け座ロッド９に相対的に作用する。このとき、受け座ロッド９は、受け座６の第１、第２プレート７、８の第１、第２細長開口１０、１５に沿って滑動し、受け座ロッド９の直径よりも小さい幅Ｌの第１、第２細長開口１０、１５の中に位置するようになる。
受け座ロッド９の原位置から末端位置への移行は、第１、第２細長開口１０、１５の中における受け座ロッド９の移動と、受け座ロッド９と第１、第２細長開口１０、１５の側面との少なくとも一方の機械的変形を伴って行われる。 The bonnet 1 has a tendency to fall along the first direction 5 when affected by an impact from a pedestrian. The receiving rod 9 is supported by the second part 3 of the locking device attached to the member of the vehicle body 4, and the resistance force facing the second direction 14 is supported by the bottom of the receiving rod passing opening 23. It acts on the receiving rod 9 relatively. At this time, seat rods 9, the first seat 6, the first second plate 7,8, along the second elongated opening 10, 15 slide, a width smaller than the diameter of the accepted seat rod 9 It is located in the first and second elongated openings 10 and 15 of L.
The transition from the original position to the end position of the receiving rod 9 is the movement of the receiving rod 9 in the first and second elongated openings 10 and 15, and the receiving rod 9 and the first and second elongated openings 10 and 15. This is done with mechanical deformation of at least one of the fifteen side surfaces.

受け座ロッド９と第１、第２細長開口１０、１５の全体は、ボンネット１の開放時と閉鎖時に正常に作用するロック装置の力を受け止め、また、衝突の際には、歩行者からの機械的なエネルギの一部を、原形態から末端形態への受け座６の移行によって吸収するように、寸法決めされる。
受け座ロッド９と第１、第２細長開口１０、１５の側面との少なくとも一方の機械的変形は、歩行者の衝突によってもたらされる機械的なエネルギの量の一部を吸収することを可能にする。この量は、受け座ロッド９と第１、第２のプレート７、８を構成する材料の性質と、それらの幾何学的な寸法に応じて変化する。
このため、第１、第２細長開口１０、１５の側面のみが対称な圧延による変形を受けるように、受け座ロッド９は、第１プレート７と第２プレート８の材料よりも硬度が高い材料で形成される。
第１プレート７と第２プレート８の厚さは、第１、第２細長開口１０、１５の側面の圧延が実行されるための機械的拘束力を最小に調整し、また、原位置と末端位置の間における受け座ロッド９の前進に対する抵抗力の変化を相対的に調整するように選定される。 The entire receiving rod 9 and the first and second elongated openings 10 and 15 receive the force of the locking device that normally operates when the bonnet 1 is opened and closed, and in the event of a collision, The mechanical energy is partly dimensioned to be absorbed by the transition of the receiving seat 6 from the original form to the end form.
Mechanical deformation of at least one of the receiving rod 9 and the side surfaces of the first and second elongated openings 10, 15 makes it possible to absorb part of the amount of mechanical energy brought about by the pedestrian collision. To do. This amount varies depending on the nature of the material comprising the receiving rod 9 and the first and second plates 7 , 8 and their geometric dimensions.
For this reason, the receiving rod 9 is a material whose hardness is higher than the material of the first plate 7 and the second plate 8 so that only the side surfaces of the first and second elongated openings 10 and 15 are subjected to deformation due to symmetrical rolling. Formed with.
The thicknesses of the first plate 7 and the second plate 8 adjust the mechanical restraining force for performing the rolling of the side surfaces of the first and second elongated openings 10 and 15 to the minimum, It is selected so as to relatively adjust the change of the resistance force against the advance of the receiving rod 9 between the positions.

衝突後の初期には、受け座ロッド９は、第１、第２細長開口１０、１５の中におけるそれぞれの嵌入が解除されるまで移動し、原位置を離れる。この初期における抵抗力は、受け座ロッド９の前進に比例することが望ましい。
次いで、一旦、受け座ロッド９が第１、第２細長開口１０、１５の中における嵌入から完全に解除され、第１、第２細長開口１０、１５の、第３、第４部分１２、１７の中へ差し込まれると、受け座ロッド９は、末端位置に到達するまで、比較的一定な、前進に対する抵抗力を受ける。 At the initial stage after the collision, the receiving rod 9 moves until the respective insertion in the first and second elongated openings 10 and 15 is released and leaves the original position. It is desirable that the initial resistance force is proportional to the advance of the receiving rod 9.
Then, once the seat rod 9 is first, is completely released from the fitting in the inside of the second elongated opening 10, 15, first, the second elongated opening 10, 15, third, fourth part 12 and 17 When inserted, the receiving rod 9 receives a relatively constant resistance to advancement until it reaches the end position.

本発明によって実現されるロック装置は、受け座ロッド９に作用する緩衝力の強さを、受け座ロッド９の第１、第２細長開口１０、１５に相対的な移動の全長にわたって、正確に調整することを可能にする。
例として、受け座ロッド９が、原位置に対して約２０ｍｍ離れた末端位置にあるときに、約１０００Ｎの前進に対する抵抗力を受けることが望ましい。指標となるこの値は、各自動車に特有の要求に応じて適応させることができる。
原位置を越えて末端位置までの、受け座ロッド９の前進に対する抵抗力は、安全上の最大閾値まで増加することが望ましい。このようにして、衝突の被害者に対するボンネット１の衝撃力の強さを、ある程度まで制限することができる。受け座ロッド９の変位の大きさの関数としての抵抗力の曲線は、安全上の最大閾値まで直線的に増加し、次いで、受け座６に対する受け座ロッド９の最大変位の大きさまで比較的一定値に留まる。望ましい例として、超過すべきでない安全上の最大閾値は、約１０００Ｎの受け座ロッド９の緩衝力に相当する。 The locking device realized according to the present invention accurately adjusts the strength of the buffering force acting on the receiving rod 9 over the entire length of movement relative to the first and second elongated openings 10 and 15 of the receiving rod 9. Makes it possible to adjust.
By way of example, it is desirable to receive a resistance to advance of about 1000 N when the receiving rod 9 is in an end position about 20 mm away from the original position. This index value can be adapted according to the specific requirements of each car.
It is desirable that the resistance force against the advance of the receiving rod 9 beyond the original position to the end position increases to the maximum safety threshold. In this way, the strength of the impact force of the bonnet 1 against the collision victim can be limited to some extent. The resistance force curve as a function of the magnitude of the displacement of the receiving rod 9 increases linearly up to the maximum safety threshold and is then relatively constant up to the maximum displacement magnitude of the receiving rod 9 relative to the receiving seat 6 . Stay in value. Desirable example, the maximum threshold for safety not-out exceed all correspond to the damping force of the seat rod 9 about 1000 N.

衝撃吸収が可能な本発明の新しいロック装置の受け座は、自動車工業において一般的に用いられているロック装置の形式に適応させることによって、車体の大きな変更を要することなく、多くの自動車に適用することができる。   The seat of the new locking device of the present invention capable of absorbing shocks can be applied to many automobiles without requiring major changes in the body by adapting to the type of locking device commonly used in the automotive industry. can do.
