[0002] At present, cars have become a common means of transportation for family members. On the basis of the continuous increase in car brands and car types, there are more and more improvements on car parts, making car riding more and more comfortable. Among them, car window lifters have abandoned the manual lifting method of crank handles and generally use button-type electric lifting methods, that is, electric window lifters. Electric window lifters for cars are mostly composed of motors, reducers, guide ropes, guide plates, glass mounting brackets, etc. The main switch is controlled by the driver to open and close all the door and window glasses, and the sub-switches on the inner handles of each door are controlled by the passengers to open and close each door and window glass, which is very convenient to operate.

[0003] The existing frameless car window lifter uses a steel wire that is affected by the weight pressure of the glass and the operating tension. Over time, the steel wire becomes fatigued and longer, causing the window glass to not close tightly when it reaches the top. Utility Model Content

[0004] The utility model aims to provide an automatic tightening and balancing adjustment system for a car window lifter, aiming to solve the problem of loose closing of the car window glass due to fatigue elongation of the steel wire of the existing frameless glass lifter.

[0005] To achieve the above-mentioned purpose, in a first aspect, the utility model provides an automatic tightening and balancing adjustment system for a car window lifter, comprising a tightening member and a balancing adjustment member, wherein the balancing adjustment member is arranged on one side of the tightening member, and the tightening member comprises a bottom shell, a lock buckle, a circular inverted cone stepped screw, a spring, a trumpet round mouth and a steel wire;

[0006] The circular inverted conical step screw is arranged on one side of the lock, the spring is arranged on the side of the circular inverted conical step screw away from the lock, the flared round mouth is arranged on the side of the spring away from the circular inverted conical step screw, the steel wire is fixedly connected to the flared round mouth and is located on the side of the flared round mouth away from the spring, and the bottom shell is arranged on one side of the flared round mouth.

[0007] Among them, the spring includes a spring body and a connecting plate, the connecting plate is fixedly connected to the circular inverted cone step screw and is located on the side of the circular inverted cone step screw away from the lock buckle, the spring body is fixedly connected to the connecting plate and is sleeved on the outside of the horn round mouth.

[0008] Among them, the tightening part also includes a steel wire head, a pressure tube and a locking mechanism. The steel wire head is arranged on the side of the steel wire away from the trumpet round mouth. The locking mechanism is fixedly connected to the steel wire head and is located on one side of the steel wire head. The pressure tube is connected to the locking mechanism and is located on the side of the locking mechanism away from the steel wire head.

[0009] Wherein, the balance adjustment member is a pad-resistant screw, and the pad-resistant screw is threadably connected to the bottom shell and passes through the bottom shell.

[0010] In a second aspect, the utility model also provides a method for automatically tightening and balancing a car window lifter, comprising the following steps:

[0011] After the glass lifter is assembled, the spring is compressed mutually by the circular inverted conical stepped screw and the trumpet round mouth to generate a pre-compression elastic force;

[0012] When the steel wire of the window lifter becomes longer due to fatigue, the pre-stressing elastic force causes the circular inverted cone stepped screw and the trumpet-shaped round mouth to push each other in opposite directions and tighten the fatigued and longer steel wire. The lock buckle is fixed in the trumpet-shaped round mouth, so that the steel wire is always tightened and the car window remains sealed;

[0013] After the glass lifter locks the glass, fine-tune the mounting surface of the lifter and the door by rotating the anti-drop screw with a pad, adjust the inner and outer positions of the glass, and keep the glass and door rubber strips airtight.

[0014] The utility model discloses an automatic tightening and balancing adjustment system for a car glass lifter. After the glass lifter is assembled, the circular inverted cone stepped screw and the trumpet round mouth compress the spring to generate a preload elastic force. When the steel wire of the glass lifter becomes longer due to fatigue, the preload elastic force causes the circular inverted cone stepped screw and the trumpet round mouth to push each other in opposite directions and tighten the fatigued and lengthened steel wire. Since the lock buckle cooperates with the conical tooth surface of the circular inverted cone stepped screw, the lock buckle is fixed in the trumpet round mouth, so that the circular inverted cone stepped screw can only go out but not go in, so that the steel wire of the glass lifter is always tightened, and finally the car window is kept in a sealed state, thereby solving the problem of the car window glass not being closed tightly due to the fatigue and elongation of the steel wire in the existing frameless glass lifter.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] See also Figures 1 to 4 In the first aspect, the utility model provides an automatic tightening and balance adjustment system for an automobile window lifter, comprising a tightening member and a balance adjustment member, wherein the balance adjustment member is arranged on one side of the tightening member, and the tightening member comprises a bottom shell 1, a lock buckle 2, a circular inverted conical stepped screw 3, a spring, a trumpet round mouth 4 and a steel wire 5; the circular inverted conical stepped screw 3 is arranged on one side of the lock buckle 2, the spring is arranged on the side of the circular inverted conical stepped screw 3 away from the lock buckle 2, the trumpet round mouth 4 is arranged on the side of the spring away from the circular inverted conical stepped screw 3, the steel wire 5 is fixedly connected to the trumpet round mouth 4 and is located on the side of the trumpet round mouth 4 away from the spring, and the bottom shell 1 is arranged on one side of the trumpet round mouth 4.

[0024] In this embodiment, after the glass lifter is assembled, the circular inverted cone stepped screw 3 and the trumpet-shaped circular mouth 4 compress the spring against each other to generate a pre-stressed elastic force; when the steel wire 5 of the glass lifter becomes fatigued and elongated, the pre-stressed elastic force causes the circular inverted cone stepped screw 3 and the trumpet-shaped circular mouth 4 to push each other away in opposite directions, and tighten the fatigued and elongated steel wire 5. Since the lock buckle 2 cooperates with the conical tooth surface of the circular inverted cone stepped screw 3, the lock buckle 2 is fixed in the trumpet-shaped circular mouth 4, so that the circular inverted cone stepped screw 3 can only move out but not in, so that the steel wire 5 of the glass lifter is always tightened, and finally the car window is kept in a sealed state, thereby solving the problem of the car window glass not being closed tightly due to the fatigue and elongation of the steel wire 5 in the existing frameless glass lifter.

[0025] Furthermore, the spring includes a spring body 6 and a connecting plate 7, the connecting plate 7 is fixedly connected to the circular inverted conical step screw 3, and is located on the side of the circular inverted conical step screw 3 away from the lock buckle 2, the spring body 6 is fixedly connected to the connecting plate 7, and is sleeved on the outside of the trumpet round mouth 4.

[0026] In this embodiment, the connection plate 7 is provided to facilitate the connection between the spring body 6 and the circular inverted cone stepped screw 3. The spring body 6 is compressed by the circular inverted cone stepped screw 3 and the trumpet-shaped round mouth 4 to generate a preload elastic force.

[0027] Furthermore, the tightening member also includes a steel wire head 8, a pressure tube 9 and a locking mechanism 10. The steel wire head 8 is arranged on the side of the steel wire 5 away from the trumpet-shaped round mouth 4. The locking mechanism 10 is fixedly connected to the steel wire head 8 and is located on the side of the steel wire head 8. The pressure tube 9 is communicated with the locking mechanism 10 and is located on the side of the locking mechanism 10 away from the steel wire head 8. The pressure tube 9 is connected and supported between each connecting member to provide a supporting force to keep the steel wire passing through the pressure tube 9 in a taut state.

[0028] In this embodiment, when the glass lifter moves to the top or bottom, the steel wire 5 is acted upon by the rotational force of the steel wire head 8 driven by the motor. The steel wire 5 will become longer if it runs for a long time, resulting in a larger gap between the bottom and top of the glass, so that the glass is not airtight with the top of the door when closed. The locking mechanism 10 is used to compensate for the spring force after the steel wire 5 becomes loose, so that the steel wire 5 is always taut and the glass is airtight to the top.

[0029] Furthermore, the balance adjustment member is a washer-resistant screw 11 , and the washer-resistant screw 11 is threadedly connected to the bottom shell 1 and passes through the bottom shell 1 .

[0030] In this embodiment, by rotating the pad anti-drop screw 11, the mounting surface of the lifter and the door is fine-tuned to achieve fine-tuning of the inner and outer positions of the glass, so that the glass and the door rubber strip are more tightly sealed.

[0031] The automatic tightening and balancing adjustment system for the automobile window lifter uses the pre-tension generated by the compression of the spring, cooperates with the circular inverted conical stepped screw 3 and the locking mechanism 10, so that when the tension is fatigued and elongated, the elongated part is retracted, so that the stressed steel wire 5 is always in a tightened state, so that the force of the steel wire 5 on the window glass remains unchanged, and the window remains in a closed state;

[0032] The borderless window glass runs on two guide rails, and there are slight deviations during installation, which causes the glass to be loosely closed when it reaches the top. The problem of the glass not being tightly closed can be solved by fine-tuning the anti-fall screws 11 with pads forward and backward and the left and right fine-adjustment device.

[0033] See also Figure 5 In a second aspect, the utility model also provides a method for automatically tightening and balancing an automobile glass lifter, comprising the following steps:

[0034] After the S1 glass lifter is assembled, the spring is compressed by the circular inverted cone stepped screw 3 and the trumpet round mouth 4 to generate a pre-compression elastic force;

[0035] S2 When the steel wire 5 of the window lifter becomes longer due to fatigue, the preload elastic force causes the circular inverted cone stepped screw 3 and the trumpet-shaped circular mouth 4 to push each other in opposite directions and tighten the steel wire 5 that has become longer due to fatigue. The lock buckle 2 is fixed in the trumpet-shaped circular mouth 4 so that the steel wire 5 is always tightened and the window remains sealed;

[0036] After the S3 glass lifter locks the glass, fine-tune the mounting surface of the lifter and the door by rotating the anti-drop screw 11 with a pad, adjust the inner and outer positions of the glass, and keep the glass and the door rubber strip sealed.

[0037] The above disclosure is only a preferred embodiment of the automatic tightening and balancing adjustment system of an automobile window lifter of the present invention. Of course, this cannot be used to limit the scope of rights of the present invention.
