[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] The reduction mechanism 6 further comprises a housing 61 and a gear ring 62, and a driving gear 64 rotatably mounted in the housing 61. The driving gear 64 is fixedly connected to the output end of the motor 2, and the driving gear 64 drives the gear ring 62 to rotate. Both sides of the reduction mechanism 6 are provided with connecting devices 66 symmetrically arranged. The connecting device 66 comprises an auxiliary gear 661 rotatably mounted in the housing 61 and meshing with the gear ring 62. The auxiliary gear 661 is fixedly mounted with a bevel gear 662, and a connecting rod 664 is fixedly mounted with a worm 663. The bevel gear 662 and the worm 663 are meshed. The connecting rod 664 is provided with a square groove 666. A square rod 665 which can be inserted into the square groove 666 is fixedly mounted on the emergency traction mechanism 7;

[0036] The motor 2 drives the driving gear 64 to rotate, and the rotation of the driving gear 64 can drive the gear ring 62 to rotate, and the gear ring 62 can engage the auxiliary gear 661 to rotate, and the rotation of the auxiliary gear 661 drives the bevel gear 662 to rotate, so that the bevel gear 662 can engage the worm 663 to rotate, so as to drive the connecting rod 664 to rotate. When the square rod 665 is inserted into the square groove 666, the connecting rod 664 will drive the square rod 665 to rotate.

[0037] The emergency traction mechanism 7 includes a mounting frame 71, in which a driving shaft 72 is rotatably mounted, a square rod 665 is fixed to the extended portion of the driving shaft 72, and two detachable locking mechanisms 9 are provided on the driving shaft 72. The steel wire rope 100 passes through the locking mechanism 9. When the square rod 665 is inserted into the square groove 666, the driving shaft 72 rotates so that the two locking mechanisms 9 are close to each other.

[0038] When the emergency traction mechanism 7 moves, the square rod 665 is inserted into the square groove 666, so that when the connecting rod 664 rotates, it can drive the driving shaft 72 to rotate, which will cause the two locking mechanisms 9 to move.

[0039] The locking mechanism 9 includes a threading shell 91, and locking members are provided on both sides of the threading shell 91. The locking members include a fixing member 93 and a pushing member 94 installed at the bottom of the fixing member 93. The wire rope 100 passes through the locking mechanism 9 and is located between the two fixing members 93. The pushing member 94 includes a first slope 941 and a second slope 943 fixedly installed on the mounting frame 71 and adapted to the first slope 941. A docking assembly 200 is also provided between the two threading shells 91.

[0040] When the threading shell 91 moves, the first slope 941 moves on the second slope 943, and the second slope 943 cooperates to push up the first slope 941, so that the fixing member 93 rotates to clamp the wire rope 100, and the two threading shells 91 are in contact and closed and fixed through the docking assembly 200, so that the broken wire rope 100 can be connected.

[0041] like Figure 2 As shown, specifically, the speed reduction mechanism 6 also includes a plurality of driven gears 63 rotatably mounted in a housing 61, the plurality of driven gears 63 are all meshed with a gear ring 62, a driving gear 64 is meshed with the plurality of driven gears 63, a driving disk 65 is fixedly mounted on the gear ring 62, a driving traction wheel 3 is mounted on the driving disk 65, and a protective cover 67 is also provided on the periphery of the housing 61.

[0042] The starter motor 2 drives the driving gear 64 to rotate, and the driving gear 64 meshes with the plurality of driven gears 63 to rotate, and the plurality of driven gears 63 rotate to mesh with the gear ring 62 to rotate, thereby achieving a deceleration effect.

[0043] like Figure 4 A supporting base plate 400 is provided on the side of the emergency traction mechanism 7, an electric slide 300 is installed on the supporting base plate 400, the electric slide 300 is connected to the vehicle power supply, a mounting frame 71 is installed on the electric slide 300, a partition plate 74 located in the middle of the drive shaft 72 is fixedly installed in the mounting frame 71, and reciprocating threads 73 located next to the partition plate 74 are provided on both sides of the drive shaft 72, and the thread rotation directions of the two reciprocating threads 73 are opposite.

[0044] When the steel wire rope 100 breaks, the electric slide 300 is started to move the mounting frame 71 so that the square rod 665 is inserted into the square groove 666. It should be noted that the inclination angles of the square rod 665 and the connecting rod 664 are consistent and are located on the same horizontal line.

[0045] like Figure 6 and Figure 7 As shown, the locking mechanism 9 is installed on the drive shaft 72 through the assembly component 8, and the assembly component 8 includes a base 81 threadedly installed on the drive shaft 72. The assembly component 8 also includes a fixed arc-shaped boss 82 fixed under the threading shell 91, and an arc-shaped groove 83 opened on the base 81 and adapted to the fixed arc-shaped boss 82.

[0046] The rotation of the drive shaft 72 causes the two assembly components 8 to move toward each other on the reciprocating threads 73 on both sides.

[0047] It should be noted that positioning arc grooves 84 are provided on both sides of the fixed arc-shaped protrusion 82, and side grooves 85 are provided on both sides of the arc-shaped groove 83. A spring 86 is fixedly installed in the side groove 85, and a positioning round block 87 is fixedly installed at one end of the spring 86. The top of the arc-shaped groove 83 also includes a guide groove 88 opened on the base 81.

[0048] The locking mechanism 9 is installed on the drive shaft 72 through the assembly component 8, specifically, by inserting the positioning arc groove 84 into the arc groove 83. When the fixed arc protrusion 82 enters the arc groove 83, it will squeeze the positioning block 87 to cause the spring 86 to contract, and the positioning block 87 will enter the side groove 85. When the positioning arc groove 84 completely enters the arc groove 83, the positioning block 87 is opposite to the positioning arc groove 84, so that the side groove 85 rebounds and the positioning block 87 is stuck in the positioning arc groove 84, so that the threading shell 91 and the base 81 are connected.

[0049] A cavity 92 is provided on both sides of the threading shell 91, and a movable cavity 500 is provided in the threading shell 91. The fixing member 93 includes a first mounting portion 931 located in the cavity 92, a second mounting portion 932 located outside the threading shell 91, and a pressure portion 933 located in the movable cavity 500. The first mounting portion 931 is movably mounted on a rod portion 934, and both ends of the rod portion 934 are rotatably mounted on both sides of the cavity 92. The wire rope 100 passes through the movable cavity 500 and is located between the two pressure portions 933. An anti-slip convex seat 95 located between the two pressure portions 933 is installed at the bottom of the movable cavity 500, and a friction portion 935 is provided on the pressure portion 933. The first slope 941 is fixedly mounted on the bottom of the second mounting portion 932, and a first inclined tooth 942 is provided on the first slope 941, and a second inclined tooth 944 adapted to the first inclined tooth 942 is provided on the second slope 943.

[0050] A docking assembly 200 is installed between the two threading shells 91. The docking assembly 200 includes a docking joint 201 fixed on one threading shell 91, and also includes a docking cavity 202 opened on the other threading shell 91. The docking joint 201 is provided with a first inclined plate 203, and the docking cavity 202 is provided with a second inclined plate 204 adapted to the first inclined plate 203. Rods 96 are inserted on both sides of the anti-slip convex seat 95, and the pressure-applying portion 933 is provided with a slot 97 adapted to the rod 96. A sphere 99 is installed at the end of the rod 96, and an auxiliary protrusion 98 is fixed on the second slope 943.

[0051] The broken wire rope 100 will fall on the top of the anti-drop convex seat 95. At this time, the two threading shells 91 move along the two ends of the broken wire rope 100 respectively, so that the broken wire rope 100 will move relatively backward. As the threading shell 91 moves, the first slope 941 moves on the second slope 943, so that the first slope 941 is pushed up, so that the second mounting portion 932 is pushed, so that the rod portion 934 can drive the pressure portion 933 to rotate, so that the two pressure portions 93 3 are close to each other, and as the first slope 941 is continuously pushed up, the two pressure applying parts 933 are also continuously approached, and finally the wire rope 100 is clamped and fixed, and the friction force on the wire rope 100 is increased by the setting of the friction part 935 to prevent it from escaping, and at this time, the first inclined teeth 942 and the second slope 943 are stuck to each other, further preventing the wire rope 100 from escaping, so that finally as the two threading shells 91 are continuously approached, the two threading shells 91 are finally docked, so that the docking The head 201 is inserted into the docking cavity 202, and the first inclined plate 203 and the second inclined plate 204 are stuck to each other, so that the two threading shells 91 are connected as a whole, and at this time, as the threading shell 91 continues to move, it will drive the insertion rod 96 to move. When the threading shell 91 moves to the end, the auxiliary protrusion 98 will abut the ball 99, so that the ball 99 drives the insertion rod 96 to rise and insert it into the slot 97 that has been tilted and aligned, so that the posture of the pressure portion 933 is fixed, and when the insertion rod 96 is inserted The two are inserted into the slot 97 to form a connection similar to an interference fit, so that the insertion rod 96 will be tightly inserted into the slot 97, the postures of the two pressure parts 933 are fixed, and there is a large friction force between the friction part 935 and the wire rope 100. Under the action of the clamping force and the friction force, the wire rope 100 can be prevented from falling off, so that the wire rope 100 is always clamped and fixed between the two pressure parts 933. The wire rope 100 is connected in this way, so that the operation can continue.

[0052] It should be noted that in this embodiment, the above is based on the fact that the break of the wire rope 100 is located near the center between the two threading shells 91. The basis for this setting is based on existing experience. In existing experience, the most common break of the wire rope 100 is the symmetrical center of its two ends, that is, in the glass lifter, it is the symmetrical center between the active traction wheel 3 and the auxiliary traction wheel 5, so the scenario used in this embodiment is this one.

[0053] However, it should be noted that, in other embodiments of the present scheme, if the breaking point of the steel wire rope 100 does not appear exactly at the symmetrical center of both ends, and the specific breaking point is offset, the present scheme may continue to be implemented.

[0054] Specifically, when the breaking point of the wire rope 100 is offset, the wire rope 100 still passes through the movable cavity 500, but compared with the above-mentioned embodiment, the wire rope 100 at one end passes through more and the wire rope 100 at the other end passes through less. It should also be noted that the wire rope 100 is formed by winding a plurality of steel wires, so the broken wire rope 100 will be divided into a plurality of exploded steel wires at its breaking point, thereby expanding its volume.

[0055] Specifically, as the threading shell 91 moves, the two fixing parts 93 will still clamp and fix the wire rope 100, but after clamping, more wire rope 100 is left at the threading shell 91 at one end, while less is left at the threading shell 91 at the other end. As the two threading shells 91 are docked, the threading shell 91 at the end with more wire rope 100 left will, during its movement, push the joint 201, so that the many exploded wire wires of the wire rope 100 at its broken part enter the docking cavity 202, thereby not affecting the docking of the two threading shells 91.

[0056] like Figure 1 As shown, the lifter body 1 further includes a slide rail 4 and auxiliary traction wheels 5 arranged at both ends of the slide rail 4. A glass mounting frame is slidably mounted on the slide rail 4. The auxiliary traction wheel 5 includes a rope part 51 and an emergency part 52.

[0057] When the steel wire rope 100 is in normal use, the steel wire rope 100 will move in the rope portion 51, and when the steel wire rope 100 is broken, it is connected through two threading shells 91, so that the broken steel wire rope 100 is connected. At this time, as the steel wire rope 100 moves, a force will be applied to the threading shell 91 to move. When the moving force is large, the fixed arc-shaped protrusion 82 will come out of the arc-shaped groove 83 and move along the guide groove 88, so that the threading shell 91 can move. When it moves to the auxiliary traction wheel 5, it will pass through the emergency portion 52, so that the glass can be opened or closed.

[0058] It should also be noted that this solution ensures that the car window glass can be opened or closed in an emergency state, and cannot replace the normal use of the wire rope 100. Therefore, this solution is an emergency solution, not a repair or replacement solution for the wire rope 100.

[0059] The specific installation of this device is as follows: first, the lifter body 1 and the emergency traction mechanism 7 are normally installed in the vehicle door, the lifter body 1 is fixed to the vehicle door frame through its base, the emergency traction mechanism 7 is fixed to the vehicle door frame through the support bottom plate 400, and the slide rail 4 is also fixed to the vehicle door frame.

[0060] A method for using a motor device for a vehicle window glass lifter comprises the following steps:

[0061] S1: When the wire rope 100 breaks, the electric slide 300 is started to move the mounting frame 71 toward the speed reduction mechanism 6, so that the square rod 665 is inserted into the square groove 666, and the motor 2 is started to drive the gear ring 62 to rotate through the driving gear 64, and the gear ring 62 rotates to engage the auxiliary gear 661, so that the bevel gear 662 engages the worm 663, so that the connecting rod 664 drives the square rod 665 to rotate;

[0062] S2: When the square rod 665 rotates, it drives the driving shaft 72 to rotate, so that the two bases 81 drive the locking mechanism 9 to move on the driving shaft 72, and the two bases 81 drive the locking mechanism 9 to move closer to each other;

[0063] S3: When the two locking mechanisms 9 move closer, the second slope 943 cooperates to lift the first slope 941, so that the fixing member 93 moves, so that the two pressure parts 933 can move closer to each other to clamp and fix the broken end of the wire rope 100. As the two threading shells 91 continue to move, the two threading shells 91 are connected through the docking assembly 200, and the clamping posture of the pressure part 933 can be fixed by inserting the insertion rod 96 into the slot 97;

[0064] S4: When the two threading shells 91 are connected, the steel wire rope 100 is connected through the connection of the threading shells 91, so that it can continue to move under the action of the active traction wheel 3. At this time, the steel wire rope 100 will move in the rope part 51 of the auxiliary traction wheel 5, and the threading shell 91 will move in the emergency part 52 when it moves to the auxiliary traction wheel 5, thereby driving the glass mounting frame on the slide rail 4 to move, thereby realizing the movement of the glass.
