Description

  The present invention relates to a vehicle management apparatus that manages vehicles entering and leaving a predetermined parking space.

  Recently, paid parking lots have become widespread, especially in large urban areas. A driver using the parking lot stops the vehicle in a predetermined parking space. Then, the vehicle is locked by the vehicle management device installed in the parking space. Therefore, the driver cannot leave the vehicle without permission.

  2. Description of the Related Art As a conventional vehicle management device, a device is generally used that locks a vehicle by raising a lock plate (hereinafter referred to as a lock plate) below a vehicle tire.

  When the vehicle stops in the parking space, the vehicle management device detects the vehicle and raises the lock plate. And when it detects that the predetermined | prescribed charge was paid to the charge collection machine linked | linked with the vehicle management apparatus, a lock | rock will be cancelled | released by defeating a lock board.

  In addition, recently, a vehicle management device is also used that regulates the vehicle exit by lowering a blocking bar near the windshield of the vehicle.

  In such a vehicle management device, when the driver deliberately gets over the lock plate and tries to leave without paying the parking fee, or when the driver starts without noticing that it is locked, or When the blocking bar is intentionally lifted or hung from the blocking bar, there is a problem that a load is applied to the lock plate or the blocking bar, and the vehicle management device is damaged by the load.

  The above-mentioned breakage is specifically breakage of the drive device that rotates the lock plate or the blocking bar. In particular, there is a high probability that a load is applied to the drive unit of the drive device and the drive unit is damaged. Therefore, there is a demand for a drive device that is not easily damaged even when a load is applied.

Thus, for example, as in the invention described in Patent Document 1, there are many that realize a drive device that holds a lock plate by a powerful lock function of a hydraulic cylinder and is not easily damaged.
JP-A-11-62302 (published March 5, 1999)

  However, in the method using the hydraulic cylinder, in addition to the problem that the cost is high, there is a problem that the hydraulic cylinder may be damaged when a load exceeding the driving force of the hydraulic cylinder is applied.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle management apparatus that can be realized at low cost and is not easily damaged.

  The drive device according to the present invention is a vehicle management device that restricts the movement of a vehicle in order to solve the above-described problem, and a delivery-possible position that enables the delivery of the vehicle and a delivery-restricted position that prevents the delivery of the vehicle. And a lock portion that rotates to reach the final stop position, a drive device that rotates the lock portion between the unloadable position and the unloading restriction position, and the lock portion is stopped at the final stop position. The final stop position is a position that is reached by turning the lock part in a direction away from the detachable position starting from the evacuation restriction position when a load is applied to the lock part. The drive device includes a drive cylinder having a cylinder rod that performs a reciprocating linear motion, and a drive that rotates the lock portion by operating with the motion of the cylinder rod. The drive cylinder is supported by a support portion coupled to the frame of the drive device, and is displaceable with respect to the support portion. The drive cylinder further includes the lock portion. When the lock portion is rotated by applying a load to the lens, it is displaced in conjunction with the rotation.

  According to said structure, a driving force transmission means act | operates with the reciprocating linear motion of the cylinder rod with which a drive cylinder is provided, As a result, a lock | rock part rotates between the leaving possible position and the leaving regulation position. Regardless of such normal operation, when a load is applied to the lock portion at the unloading restriction position in a direction away from the unloadable position, the load is transferred to the cylinder via the driving force transmission means. It is transmitted to the rod.

  At this time, if the driving cylinder is fixed to the frame of the driving device, the cylinder rod is likely to be displaced with respect to the driving cylinder by the load. In other words, there is a high possibility that the cylinder rod is pulled out from the drive cylinder or the cylinder rod is pushed into the drive cylinder.

  On the other hand, in the above configuration, the drive cylinder is attached to the frame of the drive device via the support portion, and the drive cylinder can be displaced with respect to the support portion. Therefore, the entire drive cylinder is displaced relative to the support portion before the cylinder rod is displaced relative to the drive cylinder due to the load.

  And the lock | rock part rotated by the said load stops by contact | abutting to a stop part. This position is the final stop position. In other words, the lock portion rotates to the final stop position when the load is applied.

  Further, when the lock portion stops at the final stop position, the drive cylinder displaced in conjunction with the rotation of the lock portion also stops.

  As described above, the load applied to the lock portion is finally applied to the stop portion, and it is unlikely that the load is applied to the drive cylinder. Therefore, it is possible to reduce the possibility that the drive cylinder is damaged by the operation of the drive cylinder due to the load, and to realize a vehicle management device that is not easily damaged at low cost.

  In addition, the said lock part should just be a member which controls the movement of a vehicle, and may be a plate shape, rod shape, lattice shape, or the shape which combined these.

  In addition, it is preferable that the driving device includes pull-back means for displacing the driving cylinder in a direction opposite to the direction of the displacement when the driving cylinder is displaced.

  When the lock portion reaches the final stop position by applying the load, the drive cylinder is also displaced from the normal operation position. In this state, the vehicle management device cannot perform normal operation even after the load is removed.

  According to the above configuration, when the drive cylinder is displaced, the drive device is provided with pulling back means for displacing the drive cylinder in the direction opposite to the direction of the displacement. Therefore, the drive cylinder displaced as the lock portion rotates to the final stop position can be pulled back to the normal operation position.

  Therefore, the vehicle management device can be operated normally even after the lock portion has been rotated to the final stop position.

  Further, it is preferable that the pull-back means includes a coil spring.

  According to said structure, it is easy to change the spring property of the said coil spring by changing the raw material and shape of a coil spring, Therefore It becomes easy to adjust the pull back capability of the pull back means.

  Moreover, it is preferable that the said drive device is further provided with the buffer means which restrict | limits the displacement of the said drive cylinder.

  According to said structure, at least one part of the said load can be buffered by restrict | limiting the displacement of a drive cylinder by a buffer means.

  Therefore, the possibility that the drive cylinder is damaged can be further reduced.

  In order to solve the above-described problem, the drive device according to the present invention is a drive device for a vehicle management device including a lock unit that restricts movement of the vehicle, and the drive device is a cylinder that performs a reciprocating linear motion. Drive that rotates the lock portion between a drive cylinder having a rod and a position at which the vehicle can be unloaded and a unloading-restricted position that prevents the vehicle from unloading by operating with the movement of the cylinder rod. Restriction that restricts the operation of the driving force transmission means in conjunction with the rotation when the lock section is rotated regardless of the movement of the cylinder rod by applying a load to the force transmission means and the lock section. The drive cylinder is supported by a support portion fixed to the frame of the drive device and is displaceable with respect to the support portion. Serial drive cylinder, when in conjunction with the rotation of the locking portion is the driving force transmitting means actuated is characterized by being displaced in conjunction with the operation.

  According to the above configuration, the driving force transmitting means is operated in accordance with the reciprocating linear motion of the cylinder rod provided in the driving cylinder, and as a result, the external lock portion is rotated between the leaving position and the leaving restriction position. Move. Regardless of such normal operation, when a load is applied to the lock portion at the unloading restriction position in a direction away from the unloadable position, the load is transferred to the cylinder via the driving force transmission means. It is transmitted to the rod.

  At this time, if the driving cylinder is fixed to the frame of the driving device, there is a high possibility that the cylinder rod is pulled out of the driving cylinder or pushed into the driving cylinder.

  On the other hand, in the above configuration, the drive cylinder is attached to the frame of the drive device via the support portion, and the drive cylinder can be displaced with respect to the support portion. Therefore, the entire drive cylinder is displaced relative to the support portion before the cylinder rod is displaced relative to the drive cylinder due to the load.

  And the operation | movement of the driving force transmission means accompanying rotation of the lock part by the said load is stopped by the stop part. Thereby, the displacement with respect to the support part of a drive cylinder also stops.

  As described above, the load applied to the external lock portion is finally applied to the stop portion, and it is unlikely that the load is applied to the drive cylinder. Therefore, it is possible to reduce the possibility of the drive cylinder being damaged by the operation of the drive cylinder due to the load, and to realize a vehicle management device that is not easily damaged.

  Moreover, it is preferable that the said drive apparatus is further provided with the drawing-back means which displaces the said drive cylinder in the reverse direction to the direction of the said displacement, when the said drive cylinder is displaced.

  If the drive cylinder is displaced from the normal operation position by applying the load, the drive device cannot perform normal operation even after the load is removed.

  According to the above configuration, when the drive cylinder is displaced, the drive device is provided with pulling back means for displacing the drive cylinder in the direction opposite to the direction of the displacement. Therefore, the displaced drive cylinder can be pulled back to the normal operating position.

  Therefore, after the load is removed, the drive device can be operated normally.

  As described above, the vehicle management apparatus according to the present invention has a lockable portion that rotates to reach a position where the vehicle can be unloaded, a unloading restriction position that prevents the vehicle from unloading, and a final stop position. A drive device for rotating the lock portion between the leaving position and the unloading restriction position; and a stop portion for stopping the lock portion at the final stop position, wherein the final stop position is the lock portion. When the load is applied, the lock unit is rotated in the direction away from the unloadable position starting from the unloading restriction position. And a driving force transmission means for rotating the lock portion by operating along with the movement of the cylinder rod, and the driving cylinder includes the driving device. The drive cylinder is supported by a support unit connected to the frame, and is displaceable with respect to the support unit. Further, the drive cylinder is provided when the lock unit is rotated by applying a load to the lock unit. The configuration is such that it is displaced in conjunction with the rotation.

  Therefore, when a load is applied to the lock part, the load can be released so as not to be applied to the drive cylinder by displacing the drive cylinder in conjunction with the rotation of the lock part. Therefore, the possibility that the drive cylinder is damaged can be reduced, and an effect that a vehicle management apparatus that is not easily damaged can be realized at a low cost by a simple mechanism.

  One embodiment of the present invention will be described below with reference to FIGS. In addition, the lock part with which the vehicle management apparatus of this invention is provided should just prevent the vehicle from leaving, may be a lock plate which stands up with respect to the ground, and is a blocking bar which rotates in the air. Also good. Below, the vehicle management apparatus provided with the said lock board is mentioned as an example, and is demonstrated.

(Configuration of the vehicle management device 20)
FIG. 2 is a schematic diagram showing the configuration of the vehicle management apparatus 20 of the present embodiment.

  The vehicle management device 20 manages the vehicle by restricting the movement of the vehicle that has entered the predetermined parking space. As shown in FIG. 2, the vehicle management device 20 includes a lock plate 11 and a drive device 1 that rotates the lock plate 11.

  The lock plate 11 is a vehicle stop for restricting the movement of the vehicle that has entered the parking space, and is rotated so as to reach an exitable position, an exit restriction position, and a final stop position, which will be described later. A lifting platform 15 to be described later is disposed beside the lock plate 11.

  As shown in FIG. 2, the driving device 1 includes an electric cylinder 2 (driving cylinder), a connecting arm 3 (driving force transmitting means), a bearing 4, and a rotating shaft 5.

  The electric cylinder 2 generates a driving force for rotating the lock plate 11, and is rotatably connected to a support bar 8 (frame) passed between the two support plates 7. The support plate 7 is a pair of plate-like members that stand substantially perpendicular to the substrate 12a. Further, the support bar 8 is provided substantially in parallel with the substrate 12a and extends in a direction substantially orthogonal to an extension direction of a cylinder rod 21 described later.

  The electric cylinder 2 includes a cylinder rod 21. The driving force is generated by the reciprocating linear motion (piston motion) of the cylinder rod 21. A connecting pin 10 is provided at the tip of the cylinder rod 21, and the connecting pin 10 penetrates the cylinder rod 21 at an angle that is substantially parallel to the substrate 12 a and substantially perpendicular to the longitudinal direction of the cylinder rod 21. ing.

  The electric cylinder 2 is connected to a sensor and a power source (not shown) for detecting a vehicle that has entered the parking space through electric wiring (not shown). A more detailed structure of the electric cylinder 2 will be described later.

  The connecting arm 3 is a member having two plate-like arms arranged in parallel to each other, and converts the linear motion of the cylinder rod 21 into a rotational motion and rotates the rotary shaft 5. The connecting arm 3 is connected to the cylinder rod 21 via the connecting pin 10.

  The rotating shaft 5 is rotatably supported by bearings 4a and 4b fixed to the substrate 12a and a bearing 4c fixed to the substrate 12c, and is transmitted by the driving force of the electric cylinder 2 transmitted through the connecting arm 3. Rotate. A lock plate 11 is connected to the rotary shaft 5, and the lock plate 11 rotates as the rotary shaft 5 rotates.

(Structure of electric cylinder 2)
Next, the structure of the electric cylinder 2 will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a cross-sectional view showing the structure of the electric cylinder 2.

  As shown in FIGS. 1 and 2, the electric cylinder 2 includes a cylinder rod 21, a cylinder 22, a support cylinder (support portion) 23, a coil spring 24 (retraction means), a packing 25 (buffer means), a tip cylinder 26, and a screw. A shaft 27, a nut 28, and an electric part 29 are provided.

  In the electric cylinder 2, the screw shaft 27 is rotated by the electric portion 29, and the rotation of the screw shaft 27 is converted into a linear motion of the cylinder rod 21 by the nut 28. The mechanism for operating the cylinder rod 21 is not particularly limited as long as the cylinder rod 21 can reciprocate linearly.

  The support cylinder 23 is a cylinder that supports the cylinder 22 and is rotatably attached to the support rod 8. Specifically, the support cylinder 23 is rotatably supported by the support bar 8 by providing the rotary cylinder 9 on the outer periphery thereof and passing the support bar 8 through the internal space of the rotary cylinder 9. Further, the support cylinder 23 and the cylinder 22 are not fixed, and the cylinder 22 can be displaced with respect to the support cylinder 23.

  The coil spring 24 is disposed so as to cover a part of the outer periphery of the cylinder 22, and is provided between the electric portion 29 that is the end portion of the cylinder 22 and the support cylinder 23. The coil spring 24 is configured to displace the cylinder 22 in the reverse direction when the cylinder 22 is displaced in the direction from the support cylinder 23 toward the connecting arm 3 by applying a load to the lock plate 11. In other words, the coil spring 24 pulls the cylinder 22 back to the normal operating position.

  The tip tube 26 is a tube fixed to the outer periphery of the tip portion of the cylinder 22 on the side from which the cylinder rod 21 protrudes. The cylinder 22 is maintained by the tip tube 26 so as not to come off the support tube 23.

  The packing 25 is an annular elastic member disposed on the outer periphery of the cylinder 22 and is sandwiched between the distal end tube 26 and the support tube 23. The packing 25 is not fixed to the cylinder 22. The packing 25 only needs to be elastic, and may be a coil spring made of rubber, natural rubber, foamed polystyrene, sponge made of synthetic resin, metal, or the like mainly made of silicon. As will be described later, a part of the load applied to the lock plate 11 is buffered by the packing 25.

(Normal operation of the vehicle management device 20)
Next, the operation flow of the vehicle management apparatus 20 will be described with reference to FIG. FIG. 3 is a side view showing a state in which the lock plate 11 is located at a possible delivery position 13a, a delivery restriction position 13b, and a final stop position 13c.

  In the standby state for waiting for the vehicle to enter, the cylinder rod 21 is housed inside the cylinder 22 (not shown), and as shown in FIG. 3, the lock plate 11 is tilted to the exitable position 13a. In this state, a raised passage is formed by the lock plate 11 and the lifting platform 15, and the vehicle can be put in and out by getting over the raised passage.

  When a sensor (not shown) detects the presence of a vehicle that has entered the parking space, a receipt confirmation signal is output to the electric cylinder 2. The electric cylinder 2 that has received this warehousing confirmation signal extends the cylinder rod 21. As the cylinder rod 21 extends, the connecting arm 3 rotates, and the rotating shaft 5 rotates as the connecting arm 3 rotates. As a result, the lock plate 11 connected to the rotating shaft 5 stands up to the warehousing restriction position 13b.

  When the lock plate 11 stands at the unloading restriction position 13 b, the lock plate 11 is positioned in the vicinity of the tire 14 of the vehicle, so that the vehicle is prevented from advancing by the lock plate 11. Note that the standing angle θ of the lock plate 11 is not particularly limited as long as it can restrict the vehicle from being released.

  On the other hand, when the vehicle is allowed to leave, for example, when the driver pays a predetermined parking fee, the lock plate 11 falls to the exitable position 13a. In this case, for example, when the electric cylinder 2 receives the delivery permission signal transmitted from the toll collector, the cylinder rod 21 is contracted, and the contraction motion of the cylinder rod 21 causes the reverse operation of the extension motion. Thus, the lock plate 11 is rotated to the unloadable position 13a.

(Load buffering action of the driving device 1)
Next, when a load is applied to the drive device 1 via the lock plate 11, a mechanism for buffering the load in the drive device 1 will be described.

  Here, “when a load is applied to the drive device 1 via the lock plate 11” means that the lock plate 11 is not affected by the operation of the electric cylinder 2 by applying a load to the lock plate 11. For example, when the lock plate 11 is in the leaving regulation position, when the vehicle tries to get over the lock plate 11 or when the movement of the rotating lock plate 11 is hindered. Is assumed.

  When the rotation shaft 5 rotates by applying a load to the lock plate 11, the connecting arm 3 rotates, and as a result, a load is applied to the cylinder rod 21 connected to the connecting arm 3. In the conventional driving apparatus, the cylinder rod 21 is forcibly pushed or pulled out by the load, and as a result, the electric cylinder 2 may be damaged.

  On the other hand, in the drive device 1 of the present embodiment, the load is buffered by the following mechanism. This mechanism will be described with reference to FIGS.

  FIG. 4 is a side view for explaining the load buffering mechanism of the electric cylinder 2. FIG. 4 (a) shows the electric cylinder 2 in an unloaded state, and FIG. 4 (b) shows the load. The electric cylinder 2 in the applied state is shown.

  First, when a load is applied in a direction in which the rising angle of the lock plate 11 increases, in other words, when a load is applied in the direction in which the cylinder rod 21 is pulled out from the cylinder 22 (the direction of the arrow 34 in FIG. 4). Will be described.

  As shown in FIG. 3, when a load is applied in a direction in which the standing angle is increased with respect to the lock plate 11 at the unloading restriction position 13 b, the lock plate 11 is in a direction in which the standing angle is larger than θ ( It rotates in a direction away from the unloadable position 13a. Then, the end of the lock plate 11 that is closer to the lifting platform 15 comes into contact with the protruding portion 16 (stop portion) provided on the surface of the substrate 12b, whereby the lock plate 11 stops rotating. . The position of the lock plate 11 in this state is the final stop position 13c, and the standing angle θ ′ at this position is larger than θ.

  When the lock plate 11 is rotated to the final stop position 13c, as shown in FIG. 4B, the cylinder 22 is moved in the extending direction of the cylinder rod 21 (from the support cylinder 23 to the connecting arm 3). (Toward the direction). Hereinafter, this displacement direction is referred to as a first displacement direction.

  As described above, the possibility that the electric cylinder 2 is damaged can be reduced by displacing the cylinder 22 with respect to the support cylinder 23 before the cylinder rod 21 is pulled out of the cylinder 22 by the load. In other words, the electric cylinder 2 can be protected from the load by applying the load to the protrusion 16 without applying the load to the cylinder rod 21.

  When the cylinder 22 is displaced in the first displacement direction, the coil spring 24 provided between the electric part 29 and the support cylinder 23 is compressed. Since the coil spring 24 generates a repulsive force against this compressive stress, if the load is not applied (that is, if the tire 14 does not contact the lock plate 11), the cylinder 22 is in a direction opposite to the first displacement direction ( Hereinafter, it is displaced in the second displacement direction) and pulled back to the normal operating position.

  Next, a case where a load is applied in a direction in which the rising angle of the lock plate 11 is reduced, in other words, a case where a load is applied in a direction in which the cylinder rod 21 is pushed into the cylinder 22 will be described.

  In this case, the cylinder 22 is displaced in the second direction (not shown). Due to this displacement, the distance between the front end tube 26 and the support tube 23 is reduced, and the packing 25 disposed between the front end tube 26 and the support tube 23 is compressed. A part of the load is buffered by the elastic force of the packing 25.

  Therefore, the possibility that the electric cylinder 2 is damaged by forcibly pushing the cylinder rod 21 into the cylinder 22 can be reduced.

  As described above, when a load is applied to the lock plate 11, the load is buffered by the above-described buffer mechanism, so that the possibility that the electric cylinder 2 is damaged is reduced. Therefore, labor and cost for maintenance of the vehicle management device 20 can be reduced.

  In addition, it is not necessary to use an expensive drive source having a large driving force, such as a hydraulic cylinder or an air cylinder, and a relatively inexpensive electric cylinder can be used as the driving means, so that the cost of the vehicle management apparatus can be reduced.

  Further, by providing a final stop position 13c in addition to the exit restriction position 13b and rotating the lock plate 11 to the final stop position 13c, the degree of freedom in designing the mechanism for buffering the load applied to the lock plate 11 can be increased. It is possible to realize a vehicle management apparatus that can buffer the load more easily and reliably.

(Example of change)
In addition, this invention is not limited to embodiment mentioned above, A various change is possible in the range shown to the claim. In other words, embodiments obtained by combining technical means appropriately changed within the scope of the claims are also included in the technical scope of the present invention.

  For example, the protruding portion 16 (stopping portion) provided in the vehicle management device 20 may be anything that eventually stops the lock plate 11 at the final stop position 13c, and the shape and arrangement of the protruding portion 16 are limited to those described above. Not. For example, the shape of the protrusion 16 may be a block shape or a hollow structure. Further, in the above-described configuration, the protruding portion 16 that contacts the end portion of the lock plate 11 is provided on the surface of the substrate 12b. However, it may be provided on a portion other than the substrate 12b, or may be directly installed on the ground.

  Furthermore, in order to stop the lock plate 11 at the final stop position 13c, the rotation of the rotary shaft 5 may be restricted, and the rotation of the connecting arm 3 may be restricted. For example, when the lock plate 11 is rotated to the final stop position, a stop portion that restricts the rotation of the connecting arm 3 by contacting the connecting arm 3 may be provided in the driving device 1.

  The coil spring 24 (retraction means) provided in the vehicle management device 20 is capable of retracting the electric cylinder 2 displaced as the lock plate 11 rotates to the final stop position 13c to the normal operating position. The shape and arrangement of the coil spring 24 are not limited to those described above. For example, the coil spring may be arranged such that one end thereof is fixed in the vicinity of the support plate 7 and the other end is fixed to the connecting arm 3 or the distal end tube 26. A plurality of coil springs are arranged on the outer periphery of the cylinder 22, one end of the plurality of coil springs is connected to the support cylinder 23, and the other end is connected to the end of the electric cylinder 2 (for example, the electric unit 29. May be connected to the vicinity). Further, the retracting means is not limited to a coil spring, and may be a belt-like member that can be expanded and contracted, or may be configured by combining a plurality of types of members.

  Further, the pull-back means does not have to completely return the electric cylinder 2 to the normal operation position, and may be any one that pulls back at least partially.

  In the above configuration, the electric cylinder is used as the driving means. However, the driving cylinder may be any one provided with a cylinder and a cylinder rod, and may be a hydraulic cylinder or an air cylinder, for example.

  In the above configuration, the cylinder rod 21 extends when the lock plate 11 stands at the unloading restriction position, but the cylinder rod 21 extends when the lock plate 11 falls to the unloadable position. Also good. In this case, the displacement direction of the electric cylinder 2 due to the load is reversed from that described above, and the arrangement of the coil spring 24 and the packing 25 is also reversed.

  Further, the connection method between the electric cylinder 2 and the connection arm 3 is not limited to the above, and another connection tool may be provided between the electric cylinder 2 and the connection arm 3.

  In the above configuration, the support cylinder 23 is used as the support section. However, the support section is not limited to a cylindrical member as long as it can support the cylinder 22 so as to be displaceable. The support part may be a member having a C-shaped cross section, for example.

  Since the drive device that is not easily damaged by the load applied via the lock plate or the blocking bar is provided, a vehicle management device that can reduce the cost of maintenance can be realized.
