[0001] The invention relates to the technical field of automobile windows, and in particular to a glass lifter with an emergency window opening function. Background Art

[0002] As cars become more and more popular, people are paying more attention to the safety of vehicles. At the same time, car manufacturers are also paying more and more attention to the rescue and escape of vehicles after accidents. Although it is possible to break the car window glass to escape, for the accident personnel, this method may be difficult to implement due to the small space or the car window glass is difficult to break due to the laminated sound insulation glass. Therefore, it is particularly important to realize the function of quick window opening on the car window glass lifter to provide the occupants with an escape method of evacuating through the car window. However, the current fork arm type and rope pulley type car window glass lifters are both driven by the motor to drive the worm gear structure to directly drive the transmission component (the driving tooth in the fork arm type car window glass lifter or the driving wheel in the rope pulley type car window glass lifter) to rotate to achieve lifting. The one-way self-locking characteristics of this worm gear mechanism can realize the locking of the glass at any position in the lifting stroke to prevent the car window glass from sliding down. Therefore, there is also the problem that the window cannot be opened in an emergency. Summary of the invention

DETAILED DESCRIPTION

[0026] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0027] The specific embodiment of the present invention provides a glass lifter with an emergency window opening function, Figure 1 - Attachment Figure 3As shown, it mainly includes a clutch assembly 1, a driving device 2, a first transmission assembly 3 and a second transmission assembly 4, wherein one end of the clutch assembly 1 is transmission-connected to the worm gear assembly 5, and the other end is transmission-connected to the transmission component 6, and the clutch assembly 1 is used to realize the engagement or separation between the worm gear assembly 5 and the transmission component 6. The driving device 2 is connected to the clutch assembly 1 through the first transmission assembly 3, and is used to drive the clutch assembly 1 to switch between a separation state and an engagement state. In the separation state, the clutch assembly 1 is disconnected from the worm gear assembly 5 and the transmission component 6, so that the vehicle window glass is separated from the self-locking control of the worm gear assembly 5, so that the vehicle window glass can move; in the engagement state, the clutch assembly 1 is engaged with the worm gear assembly 5 and the transmission component 6. The transmission connection between the two components enables the worm gear assembly 5 to drive the transmission component 6 to move normally through the clutch assembly 1. At this time, the window is driven by the worm gear assembly 5 so that the window glass can be lifted and stopped normally; the driving device 2 is provided with a second transmission assembly 4, and the end of the second transmission assembly 4 away from the driving device 2 is located at the upper dead center position of the window glass mounting seat 7. The driving device 2 can drive the second transmission assembly 4 to hook the window glass and move it toward the lower dead center position of the window glass mounting seat 7. Only in this way can the lifting and lowering of the window glass be ensured in the normal situation when the driving device 2 is not in action, and the window glass can be hooked by the second transmission assembly 4 at the upper dead center position and moved toward the lower dead center position of the window glass mounting seat 7 when the driving device 2 is started. In the present application, such a driving device 2 is used to drive the clutch assembly 1 so that the transmission component 6 and the worm gear assembly 5 are separated to unlock the window glass, and then the window glass is driven down by the driving action of the driving device 2 to ensure that the window can be opened in an emergency state, thereby realizing the emergency window opening function. In addition, the driving device 2 is provided with a locking mechanism, which can lock the driving device 2 to keep the window glass in an open state, that is, to ensure that after the driving device 2 drives the window to open, the window glass remains in an open state, thereby preventing the window glass from falling back after opening when the vehicle overturns.

[0028] In the specific embodiment of the present application, the driving device 2 can be a bidirectional linear driving mechanism. Figure 5 and attached Figure 6 As shown, the first end 8 of the bidirectional linear drive mechanism is connected to the clutch assembly 1 through the first transmission assembly 3, and the second end 9 of the bidirectional linear drive mechanism is provided with the second transmission assembly 4. The driving direction of the second end 9 is the same as the moving direction of the vehicle window glass mounting seat 7 from the upper dead center position to the lower dead center position, so that the driving part that drives the clutch assembly 1 to separate can be separated from the driving part that drives the vehicle window glass to descend.

[0029] In the specific application, in conjunction with the attached Figure 5As shown, the clutch assembly 1 includes a transmission gear 10 and a connecting rod 11. One side of the transmission gear 10 is meshed with the worm gear assembly 5, and the other side is meshed with the transmission component 6. In this way, it can be ensured that the worm gear assembly 5 drives the transmission component 6 to move under normal circumstances. One end of the connecting rod 11 is coaxial with the transmission gear 10 and is rotatably connected, and the other end is connected to the first transmission assembly 3, which not only ensures that the connecting rod does not affect the rotation of the transmission gear 10, but also ensures that the transmission gear can be lifted by the connecting rod 11, so that the transmission gear 10 is separated from the worm gear assembly 5 and the transmission component 6 respectively.

[0030] In some embodiments, the first transmission component 3 includes a top block 12 and a clutch rod 13. The top block 12 is arranged on the driving device 2, and is specifically arranged at the first end 8. The movement of the top block 12 is driven by the linear drive of the driving device 2, and an inclined surface 14 is arranged on the top block 12. One end of the clutch rod 13 is rotatably connected to the outer shell 15 of the clutch assembly 1, and the other end is against the inclined surface 14. In this way, the movement of the top block 12 can drive the lifting and lowering of the other end of the clutch rod 13. The middle part of the clutch rod 13 is hinged to the connecting rod 11. In this way, the lifting and lowering of the connecting rod 11 can be driven when the other end of the clutch rod 13 is lifted and lowered, thereby driving the lifting and lowering of the transmission gear 10. When the transmission gear 10 rises, it will enter a disengaged state, and when the transmission gear 10 descends, it will enter an engaged state.

[0031] In some embodiments, the end of the inclined surface 14 close to the driving device 2 is higher than the end away from the driving device 2, so that when the driving device 2 is driven linearly to drive the top block 12, the other end of the clutch rod 13 can be pushed up by the gradually rising inclined surface 14.

[0032] In some embodiments, the combination Figure 6 and attached Figure 7 As shown, the locking mechanism includes a locking block 16, a locking groove 17 and a spring 18, the driving device 2 is a gas generator cylinder, and a mounting groove 19 is arranged on one of the cylinder rod and the inner wall of the cylinder barrel of the gas generator cylinder, and a locking groove 17 is arranged on the other. The locking block 16 is arranged in the mounting groove 19 through the spring 18, and the spring 18 has a driving force to push the locking block 16 to move toward the outside of the mounting groove 19. It should be noted that the locking block 16 and the locking groove 17 are arranged at the tail end of the cylinder rod or the open end of the inner wall of the cylinder barrel, so that the cylinder rod can be locked when it is extended to a longer state; as shown in the attached figure, Figure 6 As shown in the figure, the locking groove 17 can be set at the tail end (left end) of the cylinder rod, and the locking block 16 can be set at the head end (right end) of the inner wall of the cylinder, so that the cylinder rod can be locked when it is fully extended; Figure 7As shown, the locking groove 17 can be set at the head end (right end) of the inner wall of the cylinder, and the locking block 16 can be set at the tail end (left end) of the cylinder rod, so that locking can be achieved when the cylinder rod is fully extended.

[0033] In some embodiments, the second transmission component 4 includes a connector and a hook portion, one end of the connector is connected to the driving device 2, and the other end is provided with a hook portion, the connector can be a rod-shaped body, the hook portion is located at the upper dead point position, and the hook groove of the hook portion faces the vehicle window glass mounting seat 7, so that when the driving device 2 is driven, the vehicle window glass mounting seat 7 is hooked by the hook, thereby driving the vehicle window glass to descend.

[0034] In some embodiments, the driving device 2 is a bidirectional gas generator cylinder.

[0035] It should be noted that a group of automotive supercapacitors can be added to the electric control panel of the window glass lifter to store electrical energy. This group of capacitors is specifically used to start the cylinder driven by the micro gas generator, that is, the bidirectional gas generator cylinder in this application. Since the electrical signal required for the operation of the micro gas generator is a pulse electrical signal with a specific current value, the cylinder can be started as long as there is electricity in the capacitor, and the vehicle power supply does not need to be used, thereby ensuring the reliability of the product.

[0036] A position sensor may also be provided on the window glass lifter, and the position sensor is provided in the vehicle door. The position sensor is used to detect the position information of the window glass and transmit it to the window controller. The window controller determines whether the position information is higher than the preset position information. If so, the window lifter with the emergency window opening function is controlled to open the window urgently; otherwise, the window lifter with the emergency window opening function is not activated. In this way, the starting circuit of the two-way gas generator cylinder will be activated only when the window glass extends out of the door to a certain length in the event of a vehicle accident. The two-way gas generator cylinder will not work when the window glass extension length does not reach the designed value, so as to reduce the maintenance cost of the vehicle after an accident. The preset position information may be the state of the window glass extending out by one third. In the accident state, when it is detected that the window glass extends out by less than one third, the window may not be opened urgently; when it is detected that the window glass extends out by more than or equal to one third, the emergency window opening may be activated.
