The present invention relates to a drive device for controlling the gate bar (Gate-Bar) of the vehicle circuit breaker to move up and down stably with few components.

In general, a vehicle breaker is a device that is installed at the entrance of a large building or a large parking lot and used for controlling the entry and exit of the vehicle.

In recent years, with the increase of private vehicles, according to industrial development, business vehicles are operated separately for each company. Thus, the increase in the total number of vehicles and the securing of parking lots have thus emerged as a recent issue.

In addition, as the cost of labor increases, the introduction of unmanned systems is gradually increasing in the case of the majority of parking management facilities. Accordingly, the vehicle breakers installed at the entrance of a large building or a large parking lot are not installed together with a separate fee settlement. In many cases, only vehicle breakers that operate automatically and operate independently are installed.

As described above, when the vehicle breaker installed at the entrance of a large building or a large parking lot as an unmanned facility, the vehicle passing through it is automatically read by an access card or a pass card to determine whether the vehicle passing through the vehicle has a proper access authority. The vehicle circuit breaker is operated so that the gate bar is operated to open and close up and down, and when there is no legitimate access authority, the vehicle circuit breaker does not operate so that the vehicle circuit breaker cannot pass.

On the other hand, if a vehicle breaker is installed at the same time as the rate clearing station, after the parking fee of the passing vehicle is settled and processed at the rate clearing station, the gate bar of the vehicle breaker opens and operates by operating a separate operation button. Be sure to

1 is a perspective view illustrating a general vehicle circuit breaker.

1, a general vehicle circuit-breaker, and a driving control unit is mounted on the inside, having a housing (1) containing the motor and; A rotating shaft (2) connected to the driving part of the housing (1) and protruding out of the housing; It consists of a gate bar assembly (3) which is fixed and installed at a right angle to the rotary shaft (2).

In addition, in many cases, the gate bar assembly 3 according to the related art is integrally coupled with only the gate bar B so as to be perpendicular to the rotation shaft 2.

Accordingly, the vehicle circuit breaker having the above-described configuration may operate the gate bar assembly 3 of the vehicle circuit breaker by detecting that the vehicle is received by a sensor when the vehicle is automatically operated, or by detecting the proximity of the vehicle by a proximity sensor. If the vehicle is to be passed through, and in manual operation, a manager in charge of the vehicle, such as a billing station installed adjacent to the vehicle breaker, recognizes the receipt of the vehicle and operates a separate operation button to operate the gate bar assembly of the vehicle breaker ( Operate to lift or lower 3).

That is, when the arrival of the vehicle or the approach of the vehicle is sensed or the gate bar assembly operation button is pressed by the manager, the power is applied and the operation motor rotates, so that the driving force of the operation motor is finally passed through the power transmission device. Passed to the gate bar assembly 3, the gate bar assembly 3 is lifted or the raised gate bar assembly is lowered to its original position.

2 (a) is a perspective view showing the front of the gate bar drive device of a conventional vehicle circuit breaker, (b) is a perspective view showing the back of the gate bar drive device.

As shown in Fig. 2, a conventional vehicle circuit breaker includes: a housing 1 having a door D rotatably coupled thereto; A motor (M) coupled to the inside of the housing (1) to receive power from the outside and to rotate; A power transmission device 4 for converting and transmitting power of the motor M; A gate bar assembly (3) or a gate bar (B) rotatably coupled to one end of the power transmission device (4); A control board (5) for controlling the motor (M) and power transmission device (4); It is coupled to one side of the motor (M), it is configured to include a brake (6) controlled by the control board 5 to stop the rotation of the motor (M).

In particular, the gate bar driving device of the conventional vehicle circuit breaker, the motor (M) is coupled to the inside of the housing (1) and rotated by receiving power from the outside; A power transmission device 4 for converting and transmitting power of the motor M; A control board (5) for controlling the motor (M) and power transmission device (4); It is composed of a brake (6) controlled by the control board 5 to stop the rotation of the motor (M), looking at this as follows.

The power transmission device 4 according to the prior art receives the rotational force of the motor M to decelerate the gate bar assembly 3 or the gate bar B at a speed suitable for rotating and driving the gate bar, or (B) is a component for converting the direction of rotation at an appropriate point in time to raise or lower from the lifted state.

As shown, the conventional power transmission device 4 includes: a first drive shaft 7 which receives the rotational force of the motor M; A first drive gear (8) coupled to the first drive shaft (7) and rotating; A second drive gear 8 'which is meshed with the first drive gear 8 and rotates about a second drive shaft 7'; A first link 9 axially coupled to an edge of the second drive gear 8 '; The rotating shaft 2, which is composed of a second link 9 'that is rotatably coupled to the first link 9, is coupled to one end by the second link 9'.

As shown, the power transmission device 4 receives the power from the motor (M) to lift the gate bar (B) or the gate bar assembly (3), or to lower to the original position in the raised state In this case, the operation must be stopped at the last stage of the lifting operation, and the operation must be stopped at the last stage of the operation of lowering to the original position from the lifted state.

Therefore, in order to stop the operation as described above to stop the rotation of the motor (M), the gate bar driving device of the conventional vehicle circuit breaker is one end of the operating shaft (not shown) of the motor (M) as shown The unit should be provided with a separate device for applying a load to selectively stop the working pores, most of which employs a brake 6 using a magnetic controlled by the control board 5.

When is applied, a plurality of the brake pads are in close contact with pressure on the outer peripheral surface of the operating shaft of the motor M, and finally the operating shaft of the motor M is stopped.

However, the gate bar drive device of the conventional vehicle circuit breaker is rotated at the constant speed by the rotation of the gate bar (B) or the gate bar assembly (3), so that the rotational speed at the last stage of the lifting operation, The rotational speed at the very end of the movement from the steady state to the original position is generally high speed.

Accordingly, when the gate bar B or the gate bar assembly 3 is operated at high speed, a safety problem occurs, and the gate bar B or the gate bar assembly 3 operating at a high speed may be suddenly stopped. To this end, wear of the brake pad of the brake 6 using magnetic is severe, and the wear of the brake pad causes incomplete control of the gate bar B or the gate bar assembly 3, and sometimes the brake Dust or the like due to abrasion of the pad adversely affects the operation of the motor M, which causes damage.
