The present invention relates to a car door lock control device, and more particularly, to a car door lock control device, which is high-grade, easy to install, practical and occupies a small space.

Taiwan Patent No. 79,208,920 discloses a utility model for a vehicle door lock control device. The configuration of the vehicle door lock control device thereof is shown in FIG. As shown in the figure, the vehicle door lock control device generally consists of a lock control motor 100 and a drive motor 110, a drive rod 130 and a driven rod 132. When a key is inserted into the key hole of either door, current flows so that the lock control motor 100 rotates. When the lock control motor 100 rotates, the gear on the output shaft of the lock control motor causes the locking bar 102 to move backward in the opened position. Once the locking bar 102 is released from its locked position, the drive motor 110 immediately rotates, causing the driving rod 130 to rotate via both gears 111 and 131, thus driving the driven rod. 132 is moved outward so that a link connected to a fastening hole 133 in front of the driven rod 132 opens the door lock. However, since the locking bar 102 is a rack, it takes up a lot of space for installation and tends to damage or easily wear its teeth.

The present invention has been made to solve the above problems, it is an object of the present invention to provide a car door lock control device that is small and high-quality, easy to use and easy to install.

According to the present invention, an automobile door lock control device, which usually consists of a load, drive motor and lock control motor, is generally provided. The drive motor has a drive gear which is mounted on the output shaft thereof and engaged with the driven gear, which is mounted on the screw rod which is fitted to the driven rod via the screw joint.

The lock control motor has a swinging body mounted on its output shaft, and the body has a shoulder portion engaged with the teeth of the drive gear, so that the driven gear prevents rotational movement when the output side of the lock control motor is rotated a predetermined angle. The driven rod has a protrusion that moves the micro switch on and off while the driven rod moves, causing the micro switch to send a signal corresponding to the control box to lock or open the connected door lock. Due to the arrangement of the oscillator, the driven gear is locked or released and controlled directly by the lock control motor. By means of the arrangement of the protrusions on the driven rod, the microswitch is simultaneously operated by the driven rod, synchronously locking or opening the locks of the other doors.

Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings.

2 shows a preferred embodiment of the automobile door lock control device of the present invention, which consists of a casing 20 covered with a cover 26. The inner space of the casing 20 is divided by a plurality of partition plates into a plurality of isolation chambers holding the driven rod 30, the lock control motor 50, the drive motor 60, the micro switch 40 and related parts thereof. have. The casing 20 has an upper flange 21, which cooperates with the upper flange 21 on the cover 26 to make a sheet, forming a hole 22 for sliding the driven rod 30 therein. have. The driven rod 30 has an elongated groove hole newly centered through its fuselage, a hook hole 36 at its upper end, and a bolt hole 37 at its lower end that fits the screw rod 34. The screw rod 34 has one end connected to the support 32 and inserted into the elongated groove hole 3 through the bolt hole 37 and the opposite end fixed to the driven gear 35. The support body 32 has two opposite side edges which protrude in parallel past the driven rod 30 and are blocked by the inner wall inside the hole 22. The driven gear 35 has a stub rod 38 longitudinally aligned with the screw rod 34 at the opposite end. The stub rod 38 is inserted into the support hole 30 inside the casing 20. The support 32 and the support hole 39 are provided for supporting the screw rod 30 to be driven to rotate on its own axis. Rotation of the screw rod 34 causes the driven rod 30 to move in the longitudinal direction. The driven rod 30 further includes a protrusion for pressing or releasing the switch rod 41 on the micro switch at a proper position, so that the micro switch 40 locks or pushes the signal during the movement of the driven rod 30. It is sent to a control box (not shown), thereby causing all connection doors to be locked or opened at the same time. The two motors 50 and 60 are fitted in two opposing positions in the casing 20 with respect to the driven rod 30. The drive motor 60 has a drive gear 62 mounted on its output shaft 61 and engaged with the driven gear 35 of the screw rod 34. The lock control motor 50 has a swinging body 52 mounted on its output shaft 51.

The oscillating body 52 has a shoulder portion 53 which moves to bite into a gap between them of the driven gear when the lock control motor is turned on. Therefore, the rotational movement of the driven gear 35 is controlled. The rubber packing 28 is provided in the groove 23 around the peripheral edge of the casing 20. Once the above components are in position, the cover 26 is covered with the casing 20 and screwed into the screws 27 and finally the protective cover 29 is mounted on the driven rod 30.

Both lock control and drive motors 50 and 60 are controlled to operate by a control box (not shown).

3 and 4, when a door lock is locked with a key, a lock signal is transmitted through the control box to turn on the drive motor 60, thereby rotating the drive gear 62. FIG. Rotation of the drive gear 62 causes the driven gear 35 and the screw rod 34 to rotate, and therefore the driven rod 30 is forced to move downward. If the driven rod 30 moves downward, a door lock link (not shown) connected to the hook hole 36 at the top of the driven rod 30 causes the connecting door locks to move from the side position to the locked position. Is carried. At the same time, the protrusion 33 of the driven rod 30 presses the switch rod 41 of the micro switch 40 to send a locking signal to the control box, thereby locking all the door locks. Once all the connection door locks have been moved to the locked position, the control box sends a control signal to the lock control motor 50 which causes it to rotate. Rotation of the lock control motor 50 causes the oscillating body 52 to move its shoulder 53 to a gap between them of the driven gear 35, so that the driven gear 35 is prevented from rotating. . Therefore, no pulling force applied to the driven rod 30 can cause the connecting door locks to be moved back to the retracted position.

Referring again to FIGS. 5 and 3, when a door lock is opened with a key, a B signal is sent to the lock control motor 50 via the control box to rotate its output shaft in the reverse direction. Therefore, the shoulder portion 53 of the swinging body 52 is separated from the driven gear 35. At the same time, the control box signals the drive motor 60 to drive the driven rod 30 upward. When the driven rod 30 moves upwards, the door lock link is forced to move the connecting door locks to the closed position. When the driven rod 30 moves upward, since the protrusion 33 of the driven rod 30 is released from the switch rod 41 of the micro switch 40, the micro switch 40 signals the control box. Send all the door locks open.

In general, the vehicle door lock control device of the present invention is arranged in combination with a control box of the vehicle's central control system for controlling its door locks. Therefore, if the door locks are locked with keys, the lock cannot be opened even if the lever is inserted into the channel of the window pane.

While the present invention has been described in terms of its preferred embodiments, it will be apparent to those skilled in the art that many alternatives, modifications, and variations will be apparent. For example, an automatic locking method can be controlled via a speedometer. That is, the door locks may be automatically locked when the speed of the vehicle exceeds the fixed range, or the automatic shutoff method may be automatically executed by means of seeing the current through the spark coil when the driveway engine is shut down. In recognition of the varying degrees of variation, the scope here shall be regarded as defined in the appended claims.
