Description

  The present invention relates to a park lock device.

  A conventional parking lock device is disclosed in FIG. The parking lock device includes a substrate, a drive shaft that is provided on the substrate and is driven to rotate by an actuator, and a lock plate that rises or falls by the rotational movement of the drive shaft. The actuator provided in the park lock device is mainly composed of a motor, a gear mechanism, and a ball screw mechanism. In this park lock device, the ball screw mechanism is driven by a motor via a gear mechanism, so that the actuator expands and contracts, that is, reciprocates linearly, and thereby the drive shaft is rotationally driven.

  In this parking lock device, when the vehicle enters a predetermined position, the actuator extends and the lock plate is raised. The path of the vehicle is blocked by the standing lock plate, and the vehicle is prevented from leaving. When the parking fee is settled, the actuator is shortened and the lock plate is overlaid, so that the vehicle can be withdrawn. Thus, the park lock device is used as a simple parking facility in a pay parking lot.

  Further, FIG. 3 of Patent Document 2 discloses a park lock device in which a hydraulic cylinder is employed as an actuator. In this parking lock device, the hydraulic cylinder extends and contracts the rod to rotate the drive shaft, so that the lock plate stands or falls.

JP 2008-88665 A Japanese Patent No. 3184810

  However, if the above-described actuator configured with a ball screw mechanism is employed in the park lock device, the park lock device becomes complicated. In addition, when a hydraulic cylinder is employed as an actuator as described above, since a separate control mechanism for controlling the hydraulic pressure is required, the park lock device is also complicated. For this reason, the conventional parking lock device has a problem that the manufacturing cost increases and becomes expensive.

  On the other hand, in paid parking lots where the park lock device as described above is used, due to unauthorized use such as forcibly leaving the vehicle without paying the parking fee or preventing the lock plate from standing when parking, There is a real situation that the problem of the park lock device being damaged is unending. And the manager of a pay parking lot is forced to replace the park lock device every time it is damaged. For this reason, since the conventional parking lock device is expensive, there arises a problem that the balance of balance is not balanced between the replacement cost of the parking lock device and the lost profit due to unauthorized use.

  Therefore, there is a demand for a cheaper parking lock device from the market.

  The present invention has been made in view of the above-described conventional situation, and an object to be solved is to provide a park lock device capable of further reducing the manufacturing cost.

The parking lock device of the present invention is a parking lock device comprising a substrate, a drive shaft provided on the substrate and driven to rotate by an actuator, and a lock plate that stands or falls by the rotational movement of the drive shaft. ,
The actuator includes a motor fixed to the substrate and projecting a rotating shaft horizontally toward the tip side, a bolt connected to the tip side of the rotating shaft so as to transmit torque, a nut screwed with the bolt, Reciprocating linear motion by reciprocating linear motion of the nut based on the rotation of the rotation shaft, and having an original node body in which a profile is formed, and a follower body that is driven by the profile to rotationally drive the drive shaft ,
The board is provided with a bearing bracket that rotatably supports the bolt,
The original segment is guided by the base plate so as to be able to reciprocate linearly, and is fixed to the cam member so that the nut is sandwiched between the cam member on which the profile is formed and the cam member. It consists of an attachment member, It is characterized by the above-mentioned .

  In the park lock device of the present invention, the bolt is rotated by the motor, and the nut reciprocates linearly. For this reason, the original segment moves back and forth linearly. The follower body is driven by the profile of the original segment body, and the drive shaft is driven to rotate. Thus, in this parking lock device, it is possible to stand or fall the lock plate.

  Thus, in this park lock device, it is possible to simplify the overall configuration by simplifying the configuration of the actuator. In particular, since both bolts and nuts are products that are distributed in the market as standard products, they can be easily and inexpensively procured.

  In addition, since the park lock device employs standard bolts and nuts, even if the bolts and nuts are damaged due to unauthorized use or the like, they can be individually replaced. Moreover, it is possible to reduce the cost required for the replacement.

  Therefore, according to the park lock device of the present invention, the manufacturing cost can be further reduced.

In this park lock device, the substrate is provided with a bearing bracket that rotatably supports a bolt, and the original joint is guided to the substrate so as to be capable of reciprocating linear movement . As a result, it is possible to ensure straightness of the original joint while preventing the inevitable swing of the bolt caused by the rotation. For this reason, it becomes possible to make the lock plate stand up or fall down smoothly.

The original segment includes a cam member that is guided by the substrate so as to be capable of reciprocating linear movement , and has a profile formed thereon, and an attachment member that is detachably fixed to the cam member while sandwiching a nut between the cam member . This makes it possible to easily replace the nut.

In this park lock device, the front end face of the original nodule can be a profile. Further, the follower body is formed with a pair of rollers that roll together with the profile due to the weight of the lock plate, a shaft portion that pivotally supports both rollers, and a long hole that is integral with the drive shaft and passes through the shaft portion. It is preferable that the oscillating body includes an oscillating body and an elastic body that is provided between the oscillating body and the shaft portion and has an urging force that opposes a load in a lying direction acting on the lock plate .

  In this case, the pair of rollers roll on the profile and operate integrally with the drive shaft, so that the lock plate can be erected or laid down more smoothly.

  Further, in this parking lock device, since the elastic body is provided between the swinging body and the shaft portion that pivotally supports both rollers, the lock lock device is in a standing state and is in contact with the bottom portion of the vehicle. On the other hand, even when a load in the lying down direction is applied, the urging force of the elastic body opposes the load. For this reason, it is possible to prevent the bottom of the vehicle from being damaged by the standing lock plate. Further, when a user's foot or the like is sandwiched in the lock plate that is lying down, the follower is separated from the profile of the original segment. For this reason, a load more than the weight of the lock plate does not act on the sandwiched foot or the like, and the occurrence of injury or the like is effectively prevented.

In this park lock device, a pin hole can be provided in a radial direction at the tip of the rotating shaft. The bolt can also be a cut bolt. The dimensioned bolt has a fitting hole into which the tip of the rotating shaft is fitted, and a locking portion for fitting the tip of the rotating shaft into the fitting hole and locking the pin engaged with the pin hole. It is preferable to be formed . In this case, it is possible to easily connect the rotary shaft and the dimensioning bolt with the pin while fitting the tip of the rotary shaft into the fitting hole. Thereby, when the cutting bolt is damaged, it can be easily replaced.

The rocking body 33 is also provided with a bolt 52 for fixing the rocking shaft 54. As shown in FIG. 2, bearing brackets 53 and 55 are fixed on the fixed plate 9 on the left and right of the rocking body 33, and the rocking shaft 54 is pivotally supported by the bearing brackets 53 and 55.

  The swing shaft 54 and the drive shaft 5 are coaxial. The drive shaft 5 is fixed to the swing shaft 54 protruding from the bearing bracket 55 via a joint fuse 56. As shown in FIGS. 1 and 2, a lock plate 7 is integrally fixed to the drive shaft 5. As shown in FIG. 2, the joint fuse 56 has a thin plate-like fuse portion 56 a between the swing shaft 54. The fuse portion 56 a is broken when an excessive torque acts from the lock plate 7 via the drive shaft 5.

  In addition, as shown in FIG. 7, the rocking body 33 is provided with a pair of rollers 35 and 35 that are supported by a shaft portion 35 a. Both rollers 35 straddle the insertion hole 25b of the cam member 25 on the left and right, and roll the profile 25a of the cam member 25 together with the weight of the lock plate 7. Further, the swinging body 33 is formed with a long hole 33b that is parallel to the insertion hole 33a and extends vertically, and a spring chamber 33c whose lower end communicates with the long hole 33b and extends upward. The shaft portion 35a is inserted into the long hole 33b. A coil spring 41 as an elastic body is housed in the spring chamber 33c. A spring cover 43 that seals the spring chamber 33c is screwed to the rocking body 33. The lower end of the coil spring 41 presses the shaft portion 35 a, and the upper end of the coil spring 41 presses the spring cover 43. Thus, the coil spring 41 urges the shaft portion 35 a toward the lower side of the long hole 37. For this reason, if the load of the lying down direction which acts on the lock plate 7 acts, the axial part 35a and the rollers 35 and 35 can move the inside of the long hole 33b against the biasing force of the coil spring 41. . The follower body 45 is constituted by the rocking body 33, the shaft portion 35 a, the rollers 35 and 35, the coil spring 41, and the spring cover 43.

  As shown in FIGS. 2 to 4, a connection link 49 is swingably connected between the cam member 25 and the swing body 33. The connection link 49 is configured so that the rocking body 33 is not unnecessarily separated from the cam member 25.

  Further, as shown in FIGS. 3 and 4, a proximity switch C <b> 1 is provided on the side surface of the rocking body 33. The proximity switch C1 detects a roller 35 that moves upward in the long hole 33b against the urging force of the coil spring 41, thereby transmitting a control signal to the control device.

  Further, as shown in FIG. 2, the bearing bracket 53 is provided with proximity switches C2 and C3. The proximity switch C2 is configured to transmit a control signal based on the fact that the lock plate 7 is completely lying down to the control device. Further, the proximity switch C3 is configured to transmit a control signal based on the fact that the lock plate 7 is completely upright to the control device.

  In the park lock device configured as described above, when a vehicle that has entered from the direction of the arrow shown in FIG. 1 stops at a predetermined position, a detection sensor (not shown) detects the vehicle, and a control signal is sent to the control device. Send. The control device receives the control signal and drives the motor 13 as shown in FIG. When the motor 13 is driven, rotational torque is transmitted to the dimensioning bolt 17 via the rotary shaft 15, and the dimensioning bolt 17 rotates. With respect to the rotating cutting bolt 17, the nut 29 moves linearly in the mounting member 27 in the direction in which the cutting bolt 17 is pulled out, that is, in the X1 direction. For this reason, as shown in FIG. 4, the cam member 25 moves linearly in the X1 direction, and the cam member 25 pushes the rocking body 33 forward.

  For this reason, the rollers 35 and 35 roll the profile 25a of the cam member 25 in the upward direction. For this reason, the rocking body 33 is rocked in the Y1 direction, and the drive shaft 5 is rotationally driven. For this reason, the lock plate 7 is rotationally driven in the Y1 direction, and the lock plate 7 is raised. The proximity switch C3 transmits a control signal to the control device. The control device receives the control signal and stops driving the motor 13. In this way, the raising operation of the lock plate 7 is completed, and the parked vehicle is prohibited from leaving.

  On the other hand, when the settlement of the parking fee is completed, a settlement machine (not shown) transmits a control signal to the control device. By receiving the control signal from the payment machine, the control device drives the motor 13 in the reverse rotation from that during parking. As a result, the nut 29 moves linearly in the mounting member 27 in the direction in which the cutting bolt 17 is drawn, that is, in the X2 direction. As a result, the cam member 25 moves linearly in the X2 direction, and the cam member 25 tends to move away from the swinging body 33 rearward.

  For this reason, the rollers 35, 35 roll the profile 25 a of the cam member 25 in the descending direction due to the weight of the lock plate 7. At this time, the connection link 49 acts so as to pull the swinging body 33 in the X2 direction with the movement of the cam member 25, and prevents the lock plate 7 from being kept upright by the foreign matter. Thereby, the rocking body 33 rocks in the Y2 direction, and the drive shaft 5 is driven to rotate. For this reason, the lock plate 7 is rotationally driven in the Y2 direction, and the lock plate 7 is brought into a lying state. And the drive of the motor 13 is stopped because the proximity switch C2 transmits a control signal to the control device. In this way, as shown in FIG. 3, the overturning operation of the lock plate 7 is completed, and the parked vehicle is permitted to leave.

  As described above, in the park lock device, the actuator 3 is configured by the motor 13, the cutting bolt 17, the nut 29, the cam member 25, and the follower body 45. Thus, in this park lock device, the entire configuration can be simplified by simplifying the configuration of the actuator 3. In particular, the dimensioning bolt 17 and the nut 29 are both products that are distributed in the market as standard products, and therefore can be easily and inexpensively procured.

  Further, in this parking lock device, since the standard cutting bolts 17 and nuts 29 are adopted, even if the cutting bolts 17 and nuts 29 are damaged due to unauthorized use, etc. They can be exchanged individually. Moreover, it is possible to reduce the cost required for the replacement.

  Therefore, according to this park lock device, the manufacturing cost can be further reduced.

  In this park lock device, the fixed plate 9 on the substrate 1 is provided with a bearing bracket 21 that rotatably supports the dimension bolts 17. The cam member 25 is guided to the substrate 1 by a pair of guide rails 10a and 10b so as to be able to reciprocate linearly. For this reason, in this parking lock device, it is possible to ensure the straightness of the cam member 25 while preventing the inevitable swing of the dimensioned bolt 17 caused by the rotation. For this reason, in this park lock device, it is possible to make the lock plate 7 stand up or fall down smoothly.

  Further, in this park lock device, since the original joint body 23 is composed of the cam member 25 and the mounting member 27, the nut 29 can be easily replaced by removing the mounting member 27 from the cam member 25. It is possible.

  In this park lock device, the front end surface of the cam member 25 is a profile 25a. The follower body 45 includes rollers 35 and 35, a shaft portion 35 a, a rocking body 33, and a coil spring 41. For this reason, in this parking lock device, the rollers 35, 35 roll the profile 25 a, so that the lock plate 7 can be raised or laid down more smoothly.

  A coil spring 41 is housed in the spring chamber 39 in the rocking body 33. For this reason, even when a load in the fall direction acts on the lock plate 7 that is standing and in contact with the bottom of the vehicle, as shown in FIG. On the other hand, the urging force of the coil spring 41 opposes and the shaft portion 35 a moves to the upper portion 37 a of the long hole 37. Then, the proximity switch C1 detects the proximity of the rollers 35 and 35 and transmits a control signal to the control device. Thereby, the drive of the motor 13 is stopped and the standing of the lock plate 7 is stopped. For this reason, in this park lock device, it is possible to prevent the bottom portion of the vehicle from being damaged by the standing lock plate.

  Further, when a user's foot or the like is sandwiched between the lying lock plate 7, the follower body 45 is separated from the profile 25 a of the cam member 25. For this reason, a load more than the weight of the lock plate 7 does not act on the sandwiched foot or the like, and the occurrence of injury or the like is effectively prevented.

  Furthermore, in this park lock device, as shown in FIG. 6, a pin hole 15 a is provided at the tip of the rotating shaft 15, and a fitting hole 17 e and a slit 17 c are formed in the cutting bolt 17. Thereby, it is possible to easily connect the rotary shaft 15 and the cutting bolt 17 by connecting the connecting pin 19 while fitting the tip of the rotary shaft 15 into the fitting hole 17e. ing. Thereby, when the cutting bolt 17 is damaged, it can be easily replaced.
