[0002] As an indispensable standard part of the car door system, the car window lifter is used to ensure that the car window can be lifted and lowered smoothly and can stay at any position. At present, people's demand for the configuration of commercial vehicles has increased significantly. In addition to lifting and lowering the glass, the function of the glass lifter also needs to consider the stability of the glass lifting process, the glass and the size of the abnormal noise generated by the glass lifter during the driving process of the vehicle. Therefore, improving the configuration of commercial vehicles and meeting people's high requirements and user experience for commercial vehicles has become one of the important indicators for the current design of commercial vehicles.

[0003] Most commercial vehicles on the market now still use mechanical fork arm glass lifters or single rope pulley glass lifters. The above-mentioned glass lifters have the following problems: 1) The glass does not run smoothly during lifting. 2) The glass is not firmly fixed by the single rope pulley glass lifter. When the glass is lowered to any position, the glass will shake and make strange noises during the driving of the commercial vehicle. 3) The single rope pulley glass lifter has high requirements for the support and guidance of the door system. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a double-ropes glass lifter structure, a vehicle door and a commercial vehicle, which meet the user's pursuit of safe and comfortable commercial vehicles.

[0028] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present application are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0029] like Figure 1 As shown, a double-ropes glass lifter structure includes a sliding frame assembly 5, a slideway assembly and a double-ropes drive assembly, wherein the sliding frame assembly 5 is used to install the door glass;

[0030] The slideway assembly includes a slideway 3 and a bracket for fixing the slideway 3 on the door inner panel 9, and the slide frame assembly 5 is slidably mounted on the slideway 3;

[0031] The double-sheave drive assembly includes a cable assembly 2, a wire winding mechanism assembly 8 connected to the cable assembly 2, and a motor assembly 7 for driving the wire winding mechanism assembly 8. The motor assembly 7 drives the wire winding mechanism assembly 8 to work, driving the cable assembly 2 to pull the sliding frame assembly 5 to slide along the slideway 3.

[0032] In some embodiments, the cable assembly 2 includes two parts, one part is an external cable used to connect the motor assembly 7 and the pulleys installed at the upper and lower ends of the slide 3, and the other part is an internal cable that runs through the entire slide 3 and is connected to the sliding frame assembly 5. When the motor assembly 7 drives the wire winding mechanism assembly 8 to work, the external cable drives the internal cable through the pulleys at the upper and lower ends of the slide 3 to pull the sliding frame assembly 5 along the slide 3. The external cable of the cable assembly 2 is connected to the internal cable and the sliding frame assembly 5 through the pulleys installed at the upper and lower ends of the slide 3, and the internal cable is placed inside the slide 3, which helps to reduce noise and extend the service life of the cable.

[0033] In some embodiments, the wire winding mechanism assembly 8 includes a wire winding wheel, and the external cable is wound on the wire winding wheel. The external cable is wound by the wire winding wheel, thereby pulling the sliding frame assembly 5 to slide along the slideway 3.

[0034] In some embodiments, Figure 1 As shown, the bracket includes an upper bracket 1 installed at the upper end of the slide 3 and a lower bracket 6 installed at the lower end of the slide 3. The slide 3 can be stably installed on the inner panel of the door through the two brackets, and the stability is high. Figure 4 As shown, the upper bracket 1 and the lower bracket 3 adopt a Z-shaped design, which can effectively make the mounting hole of the door inner panel 9 avoid the key structure of the door inner panel, and will not cause damage to the overall structure of the door inner panel 9, thereby retaining the superior performance of the door inner panel 9.

[0035] In some embodiments, the upper bracket 1 and the lower bracket 6 are both mounted on the door inner panel 9 by means of hexagonal flange bolts 10. Figure 2 , Figure 3 As shown, the utility model is designed with an upper bracket mounting hole 9-1 for mounting the upper bracket 1 on the door inner panel 9, and the upper bracket mounting hole 9-1 is in the shape of a keyhole, that is, a large hole through which the bolt head can pass is connected to a small hole below that meets the bolt diameter. When installing the glass lifter, the assembler can first pre-reinforce the hexagonal flange bolt 10 to the upper bracket 1 without tightening it. At this time, the glass lifter can be pre-hung on the small hole through the large hole, which not only saves labor and is efficient in the installation process, but also facilitates the fixing of the lower bracket 6, thereby improving the assembly efficiency.

[0036] In some embodiments, the cable assembly 2 is installed on the door inner panel 9 through a buckle 4 to avoid abnormal noise caused by collision between the cable assembly 2 and the door during vehicle driving.

[0037] A second aspect of the utility model provides a vehicle door, on which the double-ropes type glass lifter structure is installed.

[0038] A third aspect of the utility model provides a commercial vehicle, on which the vehicle door is installed.

[0039] The specific installation process is as follows:

[0040] Combination Figure 1-Figure 4 As shown, the upper bracket mounting hole 9-1 on the door inner panel 9 of the present invention for mounting the upper bracket 1 is in the shape of a keyhole. First, the hexagonal flange bolt 10 is partially screwed into the upper bracket 1, so that the glass lifter can be pre-hung on the door inner panel 9 with the keyhole-shaped mounting hole. This design can save assembly time, reduce assembly difficulty, and improve assembly efficiency.

[0041] Then adjust the positions of the cable assembly 2 and the slideway 3 to avoid interference risks, and then use the hexagonal flange bolts 10 to fix the lower bracket 6 to the door inner panel 9, and at this time, fix the hexagonal flange bolts 10 of the upper bracket 1 in place;

[0042] Finally, the cable assembly 2 is fixed to the door inner panel 9 by means of the buckle 4, and the buckle 4 can prevent the abnormal noise caused by the collision between the cable assembly 2 and the door during the driving of the vehicle; then the door glass is put in and fixed to the mounting hole of the sliding frame assembly 5, because the double rope wheel type glass lifter fixes the door glass more firmly, so when the door glass is lowered to any position, the glass will not shake or make abnormal noise during the driving of the vehicle;

[0043] After the installation is completed, the motor assembly 7 is input with a lifting signal to rotate the motor, thereby driving the winding mechanism assembly 8 to work. The driving force is then transmitted to the sliding frame assembly 5 through the cable assembly 2. At this time, the door glass can be driven to move freely on the slide 3 to achieve glass lifting.

[0044] The double-ropes glass lifter structure of the utility model has high assembly efficiency, low requirements on the support and guidance of the door system, and can realize smooth lifting of the glass, and the glass is stable without shaking or abnormal noise.

[0045] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
