Description

  The present invention relates to a position holding mechanism for a vehicle opening / closing body. More specifically, the present invention relates to a position holding mechanism for a vehicle opening / closing body for holding an opening / closing body such as an engine hood attached to a vehicle body of a vehicle such as an automobile so as to be capable of opening and closing by hinge connection in an open position.

In general, in a vehicle such as an automobile, an engine hood as an opening / closing lid of an engine room, for example, is hinged to the vehicle body, and can be opened and closed in the up and down rotation direction. Further, a position holding mechanism for holding the engine hood in the open position is disposed between the engine hood and the vehicle body. As this position holding mechanism, for example, as shown in FIG. 9, there is known a configuration in which a long bar-shaped hood stay S is leaned between an engine hood F and a vehicle body (vehicle body panel P). . Specifically, the hood stay is pivotally supported at one end side thereof so as to be rotatable with respect to a vehicle body (for example, a radiator panel, a fender apron, etc.), and a hook is formed at the other end side portion. Then, the hood stay is held in a leaned state between the vehicle body and the engine hood by hooking the hook on the other end side of the hook into a hook hole formed in the inner side surface portion of the engine hood. . As a result, the engine hood is held in the open position.
By the way, in the position holding mechanism configured as described above, since the hood stay is leaned between the vehicle body and the engine hood in the open position, the leaning hood stay becomes an obstacle when performing maintenance work in the engine room. was there. This hood stay is necessary to hold the engine hood in the open position, but preferably a structure without a hood stay is preferable. Further, in order to increase the opening angle of the engine hood, it is necessary to set the hood stay longer, which may cause inconvenience in storage.
In order to solve the above problem, for example, Patent Document 1 described below discloses a technique in which a hood stay is disposed in the vicinity of the hinge coupling portion. As a result, the hood stay can be set short and functioned, so that the constituent members of the position holding mechanism do not hinder the maintenance work. In addition, the storability of the food stay is improved.

Japanese Utility Model Publication No. 58-27464

However, according to the above conventional technique, in order to keep the engine hood in the open position, the operation of leaning the hood stay has to be performed manually each time, which is very troublesome. Specifically, while the engine hood in the open position is supported with one hand, the hood stay must be erected with the other hand and hooked into the retaining hole of the engine hood at the same time. I had to.
Further, for example, in the case of a configuration in which the hood stay is disposed in the vicinity of the hinge coupling portion (a position where it is difficult to reach) as in the disclosed technique of Patent Document 1, while supporting the hood with one hand The other hand had to be stood with the food hand stay extended deep. That is, the above-described leaning operation is more time-consuming.

  The present invention was devised to solve the above-described problems, and the problem to be solved by the present invention is an engine attached to a vehicle body of a vehicle such as an automobile so as to be able to be opened and closed by hinges. The object is to simplify the operation necessary to hold the open / close body such as a hood in the open position.

In order to solve the above-described problems, the position holding mechanism for a vehicle opening / closing body of the present invention takes the following means.
First, a first invention of the present invention is a vehicle opening / closing body for holding an opening / closing body such as an engine hood attached to a vehicle body of a vehicle such as an automobile by a hinge connection so as to be capable of opening / closing in an open position. A predetermined position corresponding to a preset open position of the opening / closing body, which is a position holding mechanism and is integrally disposed on one member of the vehicle body side fixed side member and the opening / closing body side movable side member constituting the hinge coupling A first engagement member having an engagement recess, a second engagement member disposed on the other member and having an engagement protrusion engageable with the engagement recess of the first engagement member, and a second engagement The second engaging member is configured to elastically press and bias the engaging convex portion of the combined member toward the engaging concave portion of the first engaging member and the engaging contact surface formed to be connected to the engaging concave portion. And an urging means provided in association with the engaging projection of the second engaging member. When the opening / closing body slides along the shape of the engagement contact surface of the joint member and rotates to a predetermined open position set in advance, the engagement recess is locked in the engagement recess of the first engagement member. It restricts the movement of the body in the closing direction and holds the position.
According to the first aspect of the invention, the first engagement member and the second engagement member function at a hinge coupling portion between the opening / closing body and the vehicle body. Specifically, in the second engagement member, the engagement convex portion is pressed and urged toward the engagement contact surface of the first engagement member by the urging means. Therefore, when the opening / closing body is rotated to open, the engaging projection slides along the engaging contact surface. When the opening / closing body is rotated to a predetermined open position set in advance, the engaging convex portion is automatically (elastically) engaged and locked with the engaging concave portion. Therefore, by this engagement lock, the first engagement member and the second engagement member are brought into the engagement lock state, and the position is held in a state where the movement of the opening / closing body in the closing direction is restricted.

Next, according to a second aspect of the present invention, in the first aspect described above, the first engagement member is integrally disposed on the movable side member constituting the hinge coupling, and the second engagement member is A fixed-side member constituting the hinge coupling is pivotally supported by a support shaft, and an engaging convex portion formed on a rotating end portion of the second engaging member by the urging means is engaged with the first engaging member. It is configured to be urged to rotate in the direction of pressing toward the engagement contact surface of the member, and the engagement convex portion is supported when the opening / closing body is rotated to a predetermined open position. The engagement lock state is taken in the engagement recess of the first engagement member at a position higher than the axial center position of the shaft.
According to the second aspect of the invention, the weight of the opening / closing body is also supported by the support shaft of the second engagement member in a state where the engagement convex portion and the engagement concave portion are engaged and locked. Moreover, an engagement convex part will be in the engagement lock state which swallowed it with rotation with respect to an engagement recessed part. Therefore, the engagement lock state is stabilized.

Next, according to a third aspect of the present invention, in the first or second aspect described above, the latching means that can be latched with the engagement convex portion in the engagement locked state being removed from the engagement concave portion. Is provided.
According to the third aspect of the present invention, it is possible to hold the engagement locked state of the second engagement member as a released state by the latching means. Therefore, for example, when the opening / closing body held in the open position is closed, an operation of holding the second engagement member in a detached state is not necessary.

Next, according to a fourth aspect of the present invention, in the third aspect described above, the opening / closing body is closed to a member of the fixed side member and the movable side member on which the first engagement member is disposed. A pushing member that pushes the latching means in the latching position state to bring it into the release position state is provided.
Here, the “release position state” is a state where the second engagement member is in a position where the engagement lock function can be exhibited.
According to the fourth invention, the latching state of the latching means is released by the operation of closing the opening / closing body. That is, only by closing the opening / closing body, the second engagement member is again in a position state where the engagement lock function can be exhibited. Therefore, when the opening / closing body is opened from the closed position, the engagement lock function can always be exhibited.

Next, according to a fifth aspect of the present invention, in any one of the first to fourth aspects described above, the second engaging member is further provided with an engaging convex portion in an engagement locked state removed from the engaging concave portion. The operation rod for releasing is connected.
According to the fifth aspect, by using the operation rod, the engagement lock release operation can be performed from a separated position. Therefore, for example, the operability is further improved by setting the length of the operating rod to a length that can be easily reached from the position where the opening / closing body is opened / closed.

The present invention can obtain the following effects by taking the above-described means.
First, according to the first aspect of the present invention, the opening / closing body is only opened to a predetermined opening position set in advance, and the opening / closing body is held in the opening position without any special operation. be able to. Therefore, an extra operation such as leaning a stay between the opening / closing body and the vehicle body as in the prior art becomes unnecessary, and this work can be simplified. In addition, since the stay for standing is not required, the space between the opening / closing body and the vehicle body is not obstructed, and the work such as maintenance is not hindered. In addition, it is preferable because the position holding mechanism can be incorporated into an existing hinge structure and the components can be shared.
Furthermore, according to the second aspect of the present invention, the support strength for holding the opening / closing body in the open position can be improved. Further, the holding state of the opening / closing body can be stabilized.
Furthermore, according to the third aspect of the present invention, the engagement lock can be held in a released state. Therefore, when the opening / closing body is closed from the open position, the engagement lock does not function, so that the opening / closing body can be easily closed. In addition, the engagement lock can be switched between a state where it automatically functions and a state where it does not function depending on the purpose of use.
Further, according to the fourth aspect of the present invention, even if the engagement lock is switched to a state where it does not function, the engagement lock is automatically functioned again by closing the opening / closing body. Can be switched. Therefore, whenever the opening / closing body is opened from the closed position, the engagement lock function can be automatically exhibited.
Furthermore, according to the fifth aspect of the present invention, the engagement lock can be released more easily.

Thereby, it can hold | maintain as the state which the engagement lock of the 2nd engagement member 20 was cancelled | released. Here, the coil spring 50 corresponds to the biasing means of the present invention, and the latching portion 34 corresponds to the latching means of the present invention.
As well shown in FIG. 2, the position holding mechanism 1 can push the operation rod 30 and automatically release the hooked state by the operation of closing the engine hood F. A member 70 is provided.
Hereinafter, each configuration of the position holding mechanism 1 will be described in detail.

  First, the first engagement member 10 is integrally formed with the hood side member Hf as well shown in FIGS. 2 and 3. Therefore, the first engagement member 10 rotates integrally around the hinge center Hc as the engine hood F is opened and closed. Further, the first engagement member 10 is formed with a curved engagement contact surface 12 on a surface that comes into contact with a second engagement member 20 described later. Further, the engagement contact surface 12 is formed with an engagement recess 11 having a partially depressed shape. Specifically, as shown in FIG. 3, the engagement recess 11 is formed at a position where the engagement recess 11 engages and locks with the engagement protrusion 21 of the second engagement member 20 when the engine hood F is in the open position. ing.

Next, as well shown in FIGS. 2 and 3, the second engagement member 20 is configured entirely as a ratchet wheel and has a shape projecting to a portion on the side in contact with the first engagement member 10. The engaging convex portion 21 is formed. Specifically, the lower end portion of the second engagement member 20 is pivotally supported on the vehicle body side member Hp by the support shaft 22, and the engagement convex portion 21 is moved toward or away from the first engagement member 10. It is possible to rotate in the direction to be moved. The engagement convex portion 21 is formed in a shape that engages and locks with the engagement concave portion 11 of the first engagement member 10 when the engine hood F is in the open position state (see FIG. 3).
Here, the 2nd engagement member 20 will be in an engagement locked state with the 1st engagement member 10 as follows. First, as well shown in FIG. 2, when the engine hood F is in the closed position, the second engagement member 20 has the engagement protrusion 21 formed by the biasing action of the coil spring 50. It is hold | maintained as the state pressed by this engagement contact surface 12. Then, when the engine hood F is opened and the first engagement member 10 rotates around the hinge center Hc, the engagement convex portion 21 slides along the curved surface shape of the engagement contact surface 12. . As shown in FIG. 3, when the engine hood F is in the open position and the engagement recess 11 reaches the position of the engagement protrusion 21, the engagement protrusion is caused by the biasing action of the coil spring 50. 21 elastically enters the engaging recess 11. And the engagement convex part 21 and the engagement recessed part 11 will be in the engagement lock state which was further ingested mutually by receiving the effect | action of the weight load by the engine hood F. FIG. At this time, the weight load by the engine hood F is such that the support shaft 22 of the first engagement member 10 disposed as a lower position of the portion where the engagement convex portion 21 and the engagement concave portion 11 are engaged, and the hood hinge H. Is supported by the hinge center Hc (see FIG. 4). Thereby, as well shown in FIG. 3, the engine hood F is brought into a locked state in which movement in the closing direction is restricted and held at that position.

Next, the operation rod 30 is formed in a long shape by a steel material having flexibility as a whole. Specifically, as shown well in FIG. 3, a handle 31 for hooking a finger or the like is formed at one end of the operation rod 30. In addition, a connection portion 32 for pin-connecting the operation rod 30 to the second engagement member 20 is formed at the other end. The operation rod 30 is supported by a support member 40 that is formed integrally with the vehicle body side member Hp. Here, as well shown in FIG. 3, the support member 40 is formed integrally with the vehicle body side member Hp, and includes a first support plate portion 41 (left side shown in the figure) and a second support plate portion 42. (Right side) is standing and arranged side by side. As shown well in FIG. 5, insertion holes 41 a and 42 a for inserting the operation rod 30 are formed in each of the first support plate portion 41 and the second support plate portion 42.
Further, as well shown in FIG. 5, the operation rod 30 is elastically connected to the first support plate portion 41 by a coil spring 50. Specifically, the coil spring 50 is locked to a hook-shaped spring locking portion 33 provided on the operation rod 30 and a spring locking portion 41b formed on the first support plate portion 41, and is a compression spring. It becomes the arrangement composition which functions as. As shown well in FIG. 2, the operating rod 30 is urged in the direction in which the second engagement member 20 is pushed by the urging action of the coil spring 50. As a result, the second engagement member 20 is urged to rotate in a direction in which the engagement protrusion 21 is pressed toward the first engagement member 10.

Further, as well shown in FIG. 3, the operating rod 30 is provided with a hook-shaped hooking portion 34 at a portion near the handle 31. The latching portion 34 has a function of latching the operating rod 30 on the latching member 60 formed integrally with the vehicle body side member Hp in a state where the operation rod 30 is pulled against the urging force of the coil spring 50. It has. Here, the latching member 60 is provided with a latching plate portion 61 erected so that the operation rod 30 can be latched. As shown well in FIG. 6, the latch plate 61 has a long hole-like insertion hole 62 in which the operation rod 30 can be hooked and a hook in which the hooked operation rod 30 can be hooked. A stop hole 63 is formed. The former insertion hole 62 is formed with an opening having an expanded shape at the upper end portion of the latch plate portion 61 so as to avoid interference with the latch portion 34 of the operating rod 30. The latter retaining hole 63 is formed in a shape that warps in a branching manner from a midway position where the retaining hole 62 hangs down.
Here, the latching portion 34 of the operating rod 30 is latched by the latching member 60 as follows. First, the engine hood F (see FIG. 3) in the open position is held in a further lifted state, and the operating rod 30 is pulled against the urging force of the coil spring 50. Specifically, the operation rod 30 is pulled to a position where the latch portion 34 is further pulled than the position of the latch plate portion 61. In this state, since the operating rod 30 is supported by the support member 40, the relative height positional relationship between the latching member 60 and the operating rod 30 interferes with each other as shown in FIG. There is no positional relationship. Then, as well shown in FIG. 7, the operation rod 30 in the pulled-out state (the state shown in FIG. 6) is pushed down and hooked into the hooking hole 62 and hooked into the hooking hole 63 as it is. As a result, the operating rod 30 is held in a state of being hooked in the hooking hole 63. That is, the operating rod 30 is supported by the support member 40 (see FIG. 3) as described above. Therefore, the operating rod 30 can be held in the latched state by the elastic restoring force of the operating rod 30 by engaging the operating rod 30 in the supported state while being pushed down and bent. And in this latching state, even if the urging force of the coil spring 50 acts on the operating rod 30, the latching portion 34 is hooked on the latching plate portion 61 and latched. It is held in the pulled-out state.

Next, the pushing member 70 is provided integrally with the hood side member Hf, as well shown in FIG. Here, as well shown in FIG. 2, the pushing member 70 is pushed so as to release the operation rod 30 in the latched state by the latching member 60 by closing the engine hood F. A pushing plate portion 71 is provided upright. Specifically, as shown in FIG. 8, the pushing plate portion 71 is formed as a pushing surface 72 whose tip side surface (lower side surface shown in the drawing) is inclined in a tapered shape.
As shown well in FIG. 2, the pushing member 70 moves downward integrally with the engine hood F when the engine hood F is closed. Then, at a position before the engine hood F is in the closed position state, the push plate portion 71 interferes with the operation rod 30 in the latched state on the latch plate portion 61. Then, as well shown in FIG. 8, as the engine hood F is further closed, the pushing plate portion 71 pushes the operating rod 30 downward, and the operating rod 30 is removed from the retaining hole 63. Move to the released release position. Thereby, the latching state of the operating rod 30 can be cancelled | released. As shown in FIG. 3, the operation rod 30 in the release position is operated when the engine hood F is opened again and the pushing plate portion 71 of the pushing member 70 moves upward. The elastic restoring force of 30 moves to the original position (see FIG. 6) that does not interfere with the retaining plate portion 61. Thereby, the position holding mechanism 1 becomes a state in which the engagement lock function can be exhibited again.

Then, the usage method of a present Example is demonstrated.
First, as shown in FIG. 2, the engine hood F in the closed position is opened. Then, with the movement of the engine hood F, the engagement protrusion 21 of the second engagement member 20 is pressed against the engagement contact surface 12 of the first engagement member 10, and the engagement contact It slides along the curved surface shape of the surface 12. As shown well in FIG. 3, when the engine hood F is in the open position, the engagement convex portion 21 elastically enters and engages in the engagement concave portion 11, and the position holding mechanism 1 is automatically engaged. It becomes locked. As a result, the engine hood F is held at that position as the state where the reverse rotation is prevented in the open position.
Next, when the engine hood F in the open position is closed, first, the operation hood 30 is pulled off with the other hand while the engine hood F is supported with one hand. Thereby, the engagement lock state of the position holding mechanism 1 is released. Then, the operation rod 30 in the detached state is latched in the latching hole 63 of the latching plate portion 61 (see FIG. 7). As a result, the operating rod 30 is held in a pulled-out state (a state in which the engine hood F can be closed) in which the engagement lock state is released. Thereafter, the engine hood F is closed. Then, with the closing of the engine hood F, the operating rod 30 is pushed by the pushing member 70 to be in the release position state (see FIG. 8). Thereby, the position holding mechanism 1 becomes a state where the engagement lock function can be exhibited again.

As described above, according to the position holding mechanism 1 of the present embodiment, the engine hood F can be held in the open position only by opening the engine hood F to the open position without performing any special operation. Can do. Therefore, an extra operation such as leaning the stay S between the engine hood F and the vehicle body (vehicle body panel P) as in the prior art (see FIG. 9) is not necessary, and this work can be simplified. Moreover, since the stay for standing is unnecessary, the space between the engine hood F and the vehicle body is not obstructed. Therefore, for example, when performing maintenance work in the engine room, there is no problem. Further, the position holding mechanism 1 is configured to be incorporated in the hood hinge H, and parts are shared. Therefore, this structure can be simplified and is preferable.
Furthermore, the position holding mechanism 1 engages and locks the first engaging member 10 and the second engaging member 20 in a state where they are engulfed with each other. In this engagement locked state, the weight load of the engine hood F can be supported on the support shaft 22 of the first engagement member 10. Therefore, the engine hood F can be stably held in the open position.
Furthermore, since it can be hooked on the latch plate portion 61 in a state where the operating rod 30 is pulled off, it can be held as a state where the engagement lock is released. Accordingly, when the engine hood F is closed from the open position, the engagement lock does not function, so that the engine hood F can be easily closed. Further, it is convenient because the engagement lock can be switched between a state in which it automatically functions and a state in which it does not function according to the purpose of use.
Furthermore, even if the position holding mechanism 1 is once switched to the state where the engagement lock does not function, the position holding mechanism 1 can be switched again to the state where the engagement lock automatically functions by closing the engine hood F. . Therefore, whenever the engine hood F is opened from the closed position, the engagement lock function can be automatically exhibited.
Furthermore, since the operation for releasing the engagement lock state can be performed at a position where the operator can easily operate by using the operation rod 30, such an operation can be performed more easily.

Although the embodiment of the present invention has been described with respect to one example, the present invention can be implemented in various forms other than the above-described embodiment.
First, although the position holding mechanism 1 of the embodiment is shown as a mechanism for holding the engine hood F in the open position, the position holding mechanism 1 can be opened and closed with respect to the vehicle body such as a hatchback type opening / closing door or trunk. It can also be applied to other configurations.
Moreover, although the 2nd engagement member 20 was comprised in the shape of a ratchet wheel and the weight load of the engine hood F was supported by the support shaft 22, it was shown, It is not limited to such a form. . For example, an engagement convex portion may be provided at the distal end side portion of the operation rod, and the structure may be configured to abut against the first engagement member and lock the engagement. Further, in order to increase the support strength of the engine hood, a support member for supporting the engagement convex portion from below may be provided separately.
Moreover, although the 1st engagement member showed what formed the engagement recessed part 11 in the position of one place, you may form an engagement recessed part in several positions, for example. Thereby, it can be made to function as a ratchet mechanism which can hold | maintain an engine hood in a multistage open position state.
Moreover, although the thing which inclined the pushing surface 72 of the pushing member 70 in the taper shape was shown, you may form simply in planar shape. Further, in order to accurately release the operating rod, the pushing surface may be partially recessed to hold the operating rod. Moreover, you may make it form the hole diameter of a penetration hole widely.
