Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope protected by the utility model.

[0025] As Figs. 1-3 shown, the utility model provides a kind of electric control lock catch device for passenger car sliding sash, including push-pull handle mechanism and electric lock catch mechanism, push-pull handle mechanism includes handle base 1 and lock tongue 2, handle base 1 is installed on window glass 9, lock tongue 2 is arranged on handle base 1;Electric lock catch mechanism includes electric control base 3 and electric lock catch part, electric control base 3 is installed on window frame 10, for accommodating electric lock catch part;Electric lock catch part includes motor 4, speed reduction assembly 5, lock block 6 and control mainboard, motor 4 is connected with lock catch by speed reduction assembly 5, lock catch is correspondingly arranged with lock tongue 2, for locking or unlocking lock tongue 2;Control mainboard is electrically connected with motor 4.

[0026] The function of control mainboard is receiving and feedback signal, and control motor 4 executes corresponding action, motor 4 is the power source of driving lock block 6 action, speed reduction assembly 5 is used for amplifying torque and deceleration, to make lock block 6 can rotate smoothly, reliably, cooperate with lock tongue 2, improve the stability and reliability of locking or unlocking to window glass 9.

[0027] Handle base 1 can be used as the gripping piece of user push-pull window glass 9, convenient operation.

[0028] As optional implementation, speed reduction assembly 5 includes worm gear drive assembly, worm gear drive assembly includes worm 51 and worm gear 52, worm 51 is transmissionally connected with the output shaft of motor 4, worm gear 52 is engaged with worm 51, and transmissionally connected with lock block 6.

[0029] The worm gear transmission assembly has the one-way transmission characteristic of the power output, and when the motor 4 stops rotating, the worm gear 52 can keep the current position unchanged, so that the locking block 6 can also be stably locked in the current position, avoiding accidental unlocking caused by external force or vibration.

[0030] As an optional implementation, the speed reduction assembly 5 further comprises a first gear 53, a second gear 54, a third gear 55 and a fourth gear 56, the first gear 53 is connected with the worm gear 52 through a connecting shaft and is engaged with the second gear 54; the second gear 54 is connected with the third gear 55 through a connecting shaft, the third gear 55 is engaged with the fourth gear 56 through a connecting shaft, and the locking block 6 is connected with the fourth gear 56 through a connecting shaft.

[0031] In this way, through multi-stage speed reduction, the torque of the motor 4 is further amplified, the space components are optimized, and the overall volume is reduced.

[0032] Since the output shaft of the motor 4 is in transmission connection with the worm 51, when the motor 4 rotates, the worm 51 also rotates, thereby driving the worm gear 52 to rotate and drive the first gear 53 to rotate. Since the first gear 53 is in transmission connection with the second gear 54, the second gear 54 is driven to rotate and drive the third gear 55 to rotate. Since the third gear 55 is in transmission connection with the fourth gear 56, the fourth gear 56 is driven to rotate and drive the locking block 6 to rotate, so as to switch the locking block 6 between the locking position and the unlocking position.

[0033] As an optional implementation, the locking end of the locking tongue 2 is provided with a locking groove 21, the electric control base 3 is provided with an insertion groove 31 for the locking tongue 2 to enter and exit, the locking block 6 has an L-shaped structure, and the horizontal section 61 thereof is connected with the fourth gear 56, and the vertical section 62 thereof is matched with the locking groove 21.

[0034] When the locking block 6 rotates to the locking position, the vertical section 62 is inserted into the locking groove 21, and the two are inserted and matched, so as to lock the vehicle window glass 9.

[0035] When the locking block 6 rotates to the unlocking position, the vertical section 62 is withdrawn from the locking groove 21, so that the locking tongue 2 can move freely, so as to unlock the vehicle window glass 9, and the vehicle window glass 9 can be freely pushed and pulled to be opened.

[0036] As an optional implementation, the electric control base 3 is provided with a limit switch 7, the limit switch 7 is electrically connected with the control mainboard, and the triggering end of the limit switch 7 is correspondingly provided with the locking tongue 2.

[0037] Further, the triggering end of the limit switch 7 extends into the slot 31, so that when the lock tongue 2 is inserted into the slot 31, the triggering end of the limit switch 7 is pressed, causing the contact state of the limit switch 7 to change, and feeding back to the control mainboard, the control mainboard drives the motor 4 to work, and drives the lock block 6 to rotate through the speed reduction assembly 5, so that the lock block 6 is inserted into the locking groove 21 of the lock tongue 2, realizing the locking of the vehicle window glass 9.

[0038] As an optional implementation, the electric control base 3 is provided with a position sensor 8, which is electrically connected with the control mainboard, for detecting the position of the fourth gear 56, thereby indirectly monitoring the state of the lock block 6.

[0039] Further, the position sensor 8 includes a Hall sensor, and the fourth gear 56 is provided with a magnetic bead.

[0040] Since the lock block 6 can only reciprocate, two magnetic beads with different magnetic forces can be installed on the fourth gear 56, one magnetic bead is located at the position corresponding to the fourth gear 56 when the lock block 6 is in the locking position, and the other magnetic bead is located at the position corresponding to the fourth gear 56 when the lock block 6 is in the unlocking position.

[0041] When the magnetic bead rotates with the fourth gear 56 to the detection range of the Hall sensor, the Hall sensor can accurately detect the change of the magnetic field and generate a corresponding electrical signal feedback to the control mainboard, thereby accurately reflecting the position of the lock block 6. For example, when the lock block 6 is in the locking position, the corresponding magnetic bead is located in the detection range of the Hall sensor; when the lock block 6 is in the unlocking position, the other magnetic bead is located in the detection range of the Hall sensor.

[0042] It should be noted that the cooperation of the magnetic bead and the Hall sensor realizes position detection, which is prior art and will not be described in detail here.

[0043] As an optional implementation, the electric control base 3 is provided with an ear plate 32 on both sides, and the ear plate 32 is provided with a connecting hole 321, and the fastener passes through the connecting hole 321 and is connected with the vehicle window frame 10.

[0044] The fastener such as bolt, screw, etc. passes through the connecting hole 321 and is connected with the vehicle window frame 10, thereby stably connecting the electric control base 3 and the vehicle window frame 10 together.

[0045] As an optional implementation, it further includes an unlocking switch and a locking switch, which are arranged on the driver's console and are electrically connected with the control mainboard.

[0046] The driver starts the unlocking switch on the driver's operating platform. The unlocking switch sends an unlocking signal to the control mainboard. After the control mainboard receives the unlocking signal, the motor 4 is started in the forward direction. The locking block 6 is driven to rotate in the unlocking direction through the assembly, and gradually separates from the locking groove 21 of the locking tongue 2, and moves from the locking position to the unlocking position. When the position sensor 8 detects that the locking block 6 rotates to the unlocking position, the unlocking in-place signal is sent to the control mainboard, the control mainboard controls the motor 4 to stop rotating, and feedback to the unlocking switch to stop sending the unlocking signal. The vehicle window glass 9 is in the unlocking state at this time, and the passenger can manually push the vehicle window glass 9.

[0047] The driver starts the locking switch on the driver's operating platform. The control mainboard first detects the position of the locking block 6 and the state of the limit switch 7. If the position sensor 8 detects that the position of the locking block 6 is in the locking position, and the limit switch 7 is in contact with the locking tongue 2, it means that the window is already in the locked state, and no operation is performed. If the position sensor 8 detects that the position of the locking block 6 is in the unlocking position, and the limit switch 7 is not in contact with the locking tongue 2, that is, the window is not completely closed or the locking tongue 2 is not inserted into the insertion slot 31 at this time, the locking tongue 2 needs to be inserted into the insertion slot 31 first, and the limit switch 7 is pressed, causing the contact state of the limit switch 7 to change and feedback to the control mainboard. After the control mainboard receives the signal of the limit switch 7, the motor 4 is started to control the rotation of the locking block 6 and insert it into the locking groove 21 of the locking tongue 2, realizing the locking of the vehicle window glass 9. When the position sensor 8 detects that the locking block 6 rotates to the locking position, the locking in-place signal is sent to the control mainboard. The control mainboard controls the motor 4 to stop rotating. The vehicle window glass 9 is in the locked state at this time and cannot be manually pushed open.

[0048] Through the setting of the unlocking switch and the locking switch, the driver can remotely control the locking and unlocking of the window, improving the convenience of operation.

[0049] It should be noted that the specific circuit connection relationship between the motor 4, the limit switch 7, the position sensor 8, the unlocking switch and the locking switch and the control mainboard is prior art, and will not be described in detail here.
