Description

The present invention mainly relates to a door opening regulating device for a vehicle that can release a door opening regulating function that prevents an automobile door (hereinafter referred to as a vehicle door) from opening suddenly as necessary.

BACKGROUND ART Conventionally, a door check link (for example, see Patent Document 1) is already installed in a vehicle door in order to maintain a predetermined opening degree in several stages.

This door check link pivots the front end inner surface of the vehicle door hinged to the pillar of the vehicle body, and the tip of the door check stay, which is inserted and supported by the door check attached to the inner surface so as to be horizontally movable and retractable, to the pillar. The base end of the door check stay is provided with a stopper that comes into contact with the end surface of the housing case of the door check mechanism in which the door check stay insertion opening is formed when the vehicle door is fully opened.

The door check stay is provided with a pair of upper and lower recesses at multiple locations in its longitudinal direction, and a pair of upper and lower shoes are biased in the housing case to elastically press the door check stay against the upper and lower sides of the door check stay, respectively.

There is.

Japanese Patent Application Publication No. 9-177410

However, the force of the door check link to keep the vehicle door open is weak, so if the door is opened forcefully or a passenger leans against the vehicle door that is maintained at a predetermined opening degree by the door check, the door will remain open. If the balance of the vehicle is disrupted or if a strong wind blows suddenly while the door is opening, the vehicle door will open more rapidly than the desired opening, causing damage to passers-by and neighboring cars in the parking lot. This poses a danger of coming into contact with others.

Therefore, in the present invention, the vehicle door can be opened slowly by applying a load from an appropriate open position until it is fully opened, and when it is closed, it can be closed normally without resistance, and the load can be reduced as necessary. The object of the present invention is to provide a vehicle door opening regulating device which can be released and opened with normal operating force.

In view of the above problems, the vehicle door opening regulating device according to the present invention freely applies a load to the opening of the vehicle door from an appropriate open position to the time when the vehicle door is fully opened, and the load is applied to the closing of the vehicle door. is not given.
Specifically, in a vehicle door in which a door check stay of a door check link, which is hinged to a pillar of a vehicle body and whose tip is pivotally connected to the pillar, is inserted and supported in the front end so as to be horizontally movable, the base end of the door check stay is A circular arc gear is connected to the vehicle door via an appropriate transmission means so as to be able to swing back and forth, and the arc gear meshes with the arc gear from the appropriate opening position of the vehicle door until it is fully opened, and is restricted only in the rotational direction corresponding to the door opening direction. The present invention is characterized in that a load means is provided which includes a pinion with a rotary damper to which power is applied, and the pinion with a rotary damper in the load means is detachably attached to the arc gear.
Further, the arc gear is provided so that its position can be freely adjusted in the circumferential direction, and the initial position of meshing with the pinion can be changed.

In short, the present invention freely applies a load to the opening of the vehicle door from an appropriate open position until it is fully opened, so the load to the opening of the vehicle door can be released as necessary. The door feels heavier than usual and opens only slowly from the middle of opening until it is fully opened, so the vehicle door does not open forcefully when the door is opened, and the above-mentioned dangers caused by the sudden opening of the vehicle door occur. It is safe and the load is not applied to the closing of the vehicle door, so the vehicle door can be closed smoothly as usual.
Furthermore, if there is no need to apply resistance to the vehicle door when opening the door, the load on the door is removed and the door can be opened with the normal operating force, preventing the vehicle door from opening suddenly. It is convenient because the above-mentioned opening regulation function, which prevents the door from being stowed away, can be used flexibly as needed.

In a vehicle door in which a door check stay of a door check link, which is hinged to a pillar of a vehicle body and whose tip is pivotally attached to the pillar, is inserted and supported through the front end of the door check link so as to be horizontally movable and retractable, an appropriate transmission means is provided at the base end of the door check stay. A circular arc gear is connected to the vehicle door so as to be able to swing back and forth through the vehicle door, and the arc gear meshes with the arc gear from the appropriate open position to the full opening of the vehicle door, and a braking force is applied only in the rotational direction corresponding to the door opening direction. Since a load means consisting of a pinion with a rotary damper is provided, when the arc gear which is oscillated by the door check stay that moves forward when the vehicle door is opened engages with the pinion, the rotary damper activates the pinion, the arc gear, the transmission means, and the door check. Braking force (load) is applied to the opening operation of the vehicle door through the stay, and the vehicle door feels heavier than usual from the middle of opening until it is fully opened, and opens only slowly. .
Therefore, the vehicle door does not open forcefully when the vehicle door is opened, and the conventional danger caused by the sudden opening of the vehicle door can be eliminated, resulting in safety.
Furthermore, when closing an open vehicle door, even if the pinion is engaged with the arc gear, no braking force (load) is applied by the rotary damper, so the vehicle door can be closed smoothly as usual.
In addition, since the pinion with a rotary damper in the load means is detachably attached to the arc gear, it is possible to freely apply the load for opening the vehicle door, and when it is not necessary to apply resistance to the vehicle door when opening the door. The system removes the load on the door and allows the door to be opened with the normal operating force, and the above-mentioned door opening regulation function that prevents the vehicle door from opening suddenly can be used flexibly as needed. It's convenient.

The arc gear is provided so that its position can be adjusted in the circumferential direction, and the initial position of meshing with the pinion can be changed, so it has practical effects such as being able to adjust the opening position where the load of the vehicle door is applied as desired. It's huge.

A load is applied only to the advancing movement of the door check stay L1 corresponding to the time when the vehicle door D is fully opened from the appropriate open position, and the load is applied to the backward movement of the door check stay L1 corresponding to the closing of the vehicle door D. A load means 1 which is not applied to the operation is provided.

The load means 1 is attached to a board 2 of a predetermined shape protruding from the inner surface of the front end D1 of the vehicle door D so that front and back surfaces 2a and 2b are vertically aligned, and a transmission means 3 is attached to the base end of the door check stay L1 as appropriate. A circular arc gear 4 is connected to the front surface 2a of the base plate 2 so as to be able to swing back and forth, and the arc gear 4 is engaged with the arc gear 4 between the appropriate opening position of the vehicle door D and the time when the vehicle door D is fully opened. A pinion 6 with a rotary damper 5 applies braking force (load) only in the direction of rotation corresponding to the rotation direction.

The door check link L has a retaining block L2 at the base end and is inserted so that the upper and lower surfaces of the door check stay L1 come into frictional sliding contact with the door check stay L1, which has a pair of upper and lower recesses at multiple locations in the longitudinal direction. It consists of a case L3 that accommodates a supporting door check mechanism (not shown) and is fixed to the inner surface of the front end D1 of the vehicle door D into which the door check stay L1 is inserted, and the front end surface of the case L3 and the vehicle door. A front end face 2c of the board 2 is interposed between the front end part D1 of the board 2 and the front end face 2c of the board 2, which projects perpendicularly to the surface 2a side and is configured to allow the door check stay L1 to be inserted therethrough. is held.

The transmission means 3 holds the retaining block L2 at the base end of the door check stay L1, and the rear end surface L4 of the case L3 has an insertion opening (not shown) for the door check stay L1 when the vehicle door D is fully opened. It consists of a joint stopper 7 that comes into contact with the joint stopper 7, a universal joint 8, and a swing lever 9 equipped with an arc gear 4.

As shown in FIG. 8, the joint stopper 7 consists of a rectangular cylindrical frame 7 that is open at the top and bottom, and the frame 7 is inserted through the base end of the door check stay L1 to engage the retaining block L2. It consists of a supporting front frame part 10, and a rear frame part 11 which holds down the retaining block L2 on the front frame part 10 and has a tongue piece 11a for connecting with the universal joint 8 projecting rearward.

The front frame section 10 includes a rectangular plate-shaped front section 10a that can come into contact with the rear end surface L4, and left and right side sections 10b and 10c that project backward from the left and right ends of the front section 10a, and the left side section 10b is provided with a right side section. It is formed slightly longer than 10c, and a vertically elongated perforation 10d is provided on the rear end side, and the right side part 10c has a hook groove through which the base end of the door check stay L1 can be inserted from the middle part of the rear end to the left side of the front part 10a. At the same time, screw holes 10f are provided at the top and bottom of the right side surface portion 11c, and the proximal end of the door check stay L1 is passed through the hook groove 10e to engage and support the retaining block L2 on the inner surface of the front surface portion 10a.

The rear frame part 11 is provided with a strip plate piece 11b that can be inserted into the perforation 10d on the left side, and a rectangular plate-shaped rear part 11c that is wider above and below the strip plate piece 11b and can be disposed opposite to the front part 10a; When the plate piece 11b is inserted into the perforation 10d and the rear surface portion 11c is placed opposite the front surface portion 10a that engages and supports the retaining block L2, it abuts against the outer surface of the right side surface portion 10c so as to close the hook groove 10e. At the same time, a rectangular plate-shaped right side covering part 11e is provided with a screw insertion hole 11d that communicates with the screw hole 10f, and a screw 12 is screwed into the screw hole 10f through the screw insertion hole 11d to form a retaining block. It constitutes a joint stopper 7 that holds L2, and has a tongue piece 11a protruding from the center of the outer surface of the rear surface portion 11c.

The universal joint 8 is pivotally supported by a bifurcated clevis 13a formed vertically separately at the tip of a shaft rod 13 of a predetermined length, and a pin 15 which is prevented from coming out by a retaining ring 14 through a tongue piece 11a of the joint stopper 7. A spherical journal 13b provided at the base end of the shaft rod 13 is universally connected by a journal receiver 9b provided at the upper end 9a of the swing lever 9, and the door check stay L1 moves forward and backward in response to opening and closing of the vehicle door D. is transmitted to the swing lever 9.

The swing lever 9 has a fan-shaped lower end 9c that is concentric with the arc gear 4 and pivoted to the lower part of the substrate surface 2a, and extends upward in a band-like shape along the rear edge of the lower end 9c. The fixing screw 16 of the circular arc gear 4 is screwed into two appropriately concentric places on the surface of the lower end 9c.

The arcuate gear 4 is provided with an arcuate hole 4a for inserting a fixing screw 16 at both ends in the circumferential direction, and the arcuate gear 4 is provided in a position adjustable in the circumferential direction along the arcuate hole 4a by loosening the fixing screw 16. The initial position of meshing with the pinion 6 can be changed, and the open position where the vehicle door D is loaded can be adjusted as desired.

In the pinion 6 with the rotary damper 5, the center of the pinion 6 is fixed to the rotating shaft 5a of the rotary one-way damper 5, which generates braking force only when rotating in one direction (counterclockwise in FIG. 2).

Then, the rotating shaft 5a is inserted into a substantially rectangular shaft hole 2d drilled in a suitable position in the front of the board 2, and the pinion 6 is placed adjacent to the circular arc gear 4 in front of the board surface 2a, and a rotary damper is installed on the back surface 2b of the board. 5 is placed.

The rotary damper 5 has one protruding piece (lower in FIG. 2) that protrudes in one diameter direction pivoted to the lower part of the back surface 2b of the substrate with a pivot 17, and the circumferential circumference of the substrate 2 centered on the pivot 17. A support shaft 18, which is oriented toward the back surface 2b of the board from the other (upper side in FIG. 2) projecting piece, is movably attached to the circular arc hole 2e drilled on the top, and the pinion 6 is placed at a rear position where it can mesh with the circular gear 4. The pinion 6 is removably attached to the arc gear 4 by being able to swing freely between the front position and the front position where the pinion 6 does not mesh.

The pinion 6 is maintained in the attached/disengaged (meshing or disengaged) state with respect to the arc gear 4 by fixing the main body lying down at a proper position in the rear center of the back surface 2b of the board, and pivoting the tip of the rod 19a that reciprocates linearly back and forth to the support shaft 18. This can be achieved by the actuator 19.

The actuator 19 moves the rod 19a backward to position the support shaft 18 at the rear of the circular arc hole 2e (on the right side in FIG. 6), holds the pinion 6 at a rear position where it can mesh with the circular gear 4, and moves the rod 19a backward. By advancing the actuator 19a forward, the support shaft 18 is positioned in front of the circular arc hole 2e (on the left side in FIG. 7), and the pinion 6 is held at the forward position where it is not engaged with the circular gear 4. The movement of the rod 19a is controlled by a remote controller (not shown).

In the closed state of the vehicle door D in the door opening regulation possible state where the pinion 6 is held at the rear position where it can mesh with the arc gear 4 by the actuator 19, the arc gear 4 is not engaged with the pinion 6 and the vehicle door D is closed. The arc gear 4, which swings forward from a predetermined opening degree via the door check stay L1 and the transmission means 3, is set to mesh with the pinion 6.

Additionally, above the board 2, there is a door check stay L1 that moves forward and backward in response to the opening and closing of the vehicle door D, and a door check stay L1 that prevents the transmission means 3 from touching the board surface 2a and interfering with its movement. Along the transmission means 3, there are provided elongated holes 2f that are wide up and down and long in the front and back.

In the door opening regulating device configured as described above, by remotely controlling the actuator 19 using a remote controller, the rod 19a is moved backward and the pinion 6 is held at a rear position where it can mesh with the arc gear 4. Establishes a state in which door opening can be regulated.

When the vehicle door D is closed in this state, the door check stay L1 retreats into the vehicle door D, the joint stopper 7 is spaced apart behind the case L3, and the swing lever 9 is moved through the universal joint 8. It is tilted backward, and the arc gear 4 does not mesh with the pinion 6 (see FIGS. 1 to 3).

Then, when the vehicle door D is opened, the door check stay L1 advances and protrudes from the front end D1 of the vehicle door D, the swing lever 9 swings forward, and when the vehicle door D reaches a predetermined opening degree, the door check stay L1 advances and protrudes from the front end D1 of the vehicle door D. The gear 4 meshes with a pinion 6 to which a braking force is applied by a rotary damper 5 (see FIG. 4).

As a result, the door check stay L1 protrudes the longest from the front end D1 of the vehicle door D, the front face 10a of the joint stopper 7 touches the rear end face L4 of the case L3, and the swing lever 9 is moved through the universal joint 8. Until the forward-tilting vehicle door D is fully opened, a load is applied to the vehicle door D, and the vehicle door D feels heavier than usual and opens only slowly (see FIGS. 5 and 6).

Therefore, the vehicle door D does not open forcefully when the door is opened, and the danger caused by the sudden opening of the vehicle door D can be eliminated, resulting in safety.

In addition, when closing the vehicle door D, the door check stay L1 moves backward in the reverse order to the above, the joint stopper 7 moves back and away from the case L3, and the swing lever 9 swings rearward via the universal joint 8. However, since the pinion 6 meshing with the arc gear 4 rotates clockwise in FIG. 5 is not applied, the vehicle door D can be closed smoothly as usual without any load.

In addition, if there is no need to apply resistance to the vehicle door when opening the door, by remotely controlling the actuator 19 using a remote controller, the rod 19a is advanced forward and the pinion 6 is engaged with the arc gear 4. It is possible to hold the door in the forward position where it will not open, release the load on opening the door, and open the door with the normal operating force (see FIG. 7).
