[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-7, the utility model provides a technical solution: a fault protection control device for a vehicle window, including a car door 1. A cavity 11 is provided inside the car door 1. A window main body 12 is inserted and installed inside the cavity 11. A first lower limit seat 15 and a second lower limit seat 16 which are matched with each other are respectively fixedly and slidably installed at the lower end of the inner cavity of the cavity 11. Two upper limit seats 14 which are matched with each other are slidably installed on the lower end face of the window main body 12. Support rods 17 are rotatably installed between the two upper limit seats 14 and the first lower limit seat 15 and the second lower limit seat 16 respectively. The two support rods 17 are arranged in a scissor shape, and the middle parts of the two support rods 17 are rotatably connected to each other. A first motor box 13 is fixedly installed on the lower end face of the inner cavity of the cavity 11. A threaded rod 18 which is inserted into the second lower limit seat 16 is fixedly installed at the outer end of the first motor box 13 through its output shaft. A limit pin 2 which is in threaded cooperation with the threaded groove on the periphery of the threaded rod 18 is slidably installed inside the second lower limit seat 16. A second motor box 20 is fixedly installed on the upper end face of the second lower limit seat 16. The second motor box 20 is connected to the limit pin 2, and a storage battery 201 and an impact force sensor 202 which are electrically connected to the second motor box 20 through wires are fixedly installed on the inner wall of the cavity 11.

[0026] Working principle: When the window main body 12 is normally opened and closed, start the motor inside the first motor box 13, drive the threaded rod 18 to rotate through its output shaft. The rotating threaded rod 18 can drive the second lower limit seat 16 to move through the threaded cooperation with the limit pin 2 inside the second lower limit seat 16, shorten the distance between the second lower limit seat 16 and the first lower limit seat 15, and contract the distance between the two upper limit seats 14 through the two support rods 17 which are rotatably connected to each other, so as to achieve the effect of lifting the window main body 12 inside the car door 1. On the contrary, when the output shaft of the first motor box 13 rotates reversely, the window main body 12 can be driven to descend;

[0027] When a vehicle collision occurs and causes the door 1 to be unable to open normally, the impact sensor 202 can sense the impact force information generated by the vehicle, process the information through its internal processor, and transmit the information to the second motor box 20. The second motor box 20 drives the limit pin 2 inside the second lower limit seat 16 to move outward around the threaded rod 18, so that the limit pin 2 is separated from the thread around the threaded rod 18, thereby disconnecting the connection between the threaded rod 18 and the second lower limit seat 16. This facilitates rescue personnel outside the vehicle to manually move the window main body 12, improving the rescue effect for the people inside the vehicle, and there is no need to break the window main body 12, which can avoid secondary injuries to the people inside the vehicle. Among them, a storage battery 201 electrically connected to the second motor box 20, the impact sensor 202 and its internal processor is provided inside the door 1, which can supply power to these devices separately and make these devices independent of the vehicle driving structure. When the vehicle driving system is damaged, the restriction on the window main body 12 can still be released, further improving the safety performance of this device.

[0028] Specifically, a limit slide rail 19 is fixedly installed on the lower end surface of the window main body 12. The upper end of the limit slide rail 19 matches the top end of the inner cavity of the cavity 11, and two upper limit seats 14 are slidably installed at the lower end of the limit slide rail 19.

[0029] By setting the limit slide rail 19, not only can the movement range of the window main body 12 be restricted through its contact effect with the top end of the inner cavity of the cavity 11 to prevent the window main body 12 from falling off, but also the upper limit seats 14 can be connected to the window main body 12 through the sliding fit between it and the two upper limit seats 14, so that the upper limit seats 14 moving up and down can drive the window main body 12 to move up and down.

[0030] It should be noted that a limit slide cavity 21 and a limit rotation cavity 27 communicating with each other are formed inside the second lower limit seat 16. An activity block 22 matching the limit pin 2 is slidably installed in the limit slide cavity 21. The limit pin 2 is fixedly installed on the inner end surface of the activity block 22. A rotation ring 25 matching the outer radius of the threaded rod 18 is rotatably installed in the limit rotation cavity 27. A limit slide shaft 24 is fixedly installed on one side of the activity block 22. A driving chute 241 slidably matched with the limit slide shaft 24 is formed on one side of the rotation ring 25. A driving gear 26 meshing with the outer periphery of the rotation ring 25 is fixedly installed on the outer end surface of the second motor box 20 through its output shaft. A through cavity 28 matching the driving gear 26 is formed above the limit rotation cavity 27. A limit chute 231 is formed on the inner wall of the limit slide cavity 21. A limit slider 23 slidably matched with the limit chute 231 is fixedly installed on the other side of the activity block 22.

[0031] When driving the limit pin 2 through the second motor box 20, the internal processor of the impact force sensor 202 drives the motor inside the second motor box 20. Through its outer output shaft, the driving gear 26 is driven to rotate. Then, through the meshing effect between the driving gear 26 and the rotating ring 25, the rotating ring 25 can be driven to rotate in the limit rotation cavity 27. The limit sliding cavity 21 can limit the movement direction of the movable block 22 through the sliding fit between the limit slider 23 and the limit sliding groove 231. As a result, the rotating rotating ring 25 can drive the limit pin 2 to move outwards in the limit sliding cavity 21 through the sliding fit between the driving sliding groove 241 and the limit sliding shaft 24, causing the limit pin 2 to separate from the outer thread of the threaded rod 18. Furthermore, the threaded fit between the threaded rod 18 and the second lower limit seat 16 can be released, facilitating the manual up and down sliding of the window main body 12 outside the vehicle door 1.

[0032] It should be noted that positioning grooves 31 are provided on both sides of the lower end of the window hole of the vehicle door 1. Cleaning brushes 3 are fixedly installed symmetrically on the upper sides of the two positioning grooves 31. The two cleaning brushes 3 are arranged in an L shape, and a positioning bolt 32 connecting to the window hole of the vehicle door 1 is provided at the upper end of the cleaning brush 3.

[0033] By providing the positioning grooves 31 and cooperating with the positioning bolts 32, the two cleaning brushes 3 can be respectively installed on both sides of the lower end of the window hole of the vehicle door 1, which can not only prevent foreign impurities from entering the cavity 11, but also clean the window main body 12 during the up and down movement of the window main body 12.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
