Description

Technical Field

[0001] This invention relates to improvements in the field of automotive parts technology, and more particularly to an improved invention of a roller bracket for an automotive plastic guide rail or door module lifter. Background Technology

[0002] Window regulators are the devices that raise and lower automotive windows, primarily used to control the movement of the windows and allow them to stop at any position. Plastic guide rail or door module window regulators, thanks to the application of new materials, have achieved lightweight and integrated designs and are now widely used in ordinary passenger cars and a small portion of the SUV market. Because the main body of the glass guide mechanism in plastic guide rail or door module window regulators has been changed from metal to plastic, there is a significant risk to the structural strength of the roller fixing points. Especially under conditions of high temperature, high humidity, and vibration, the roller fixing points on the plastic guide rail or door module base plate are highly susceptible to cracking, leading to abnormal noises or even malfunction of the window raising and lowering function. Therefore, the structural design of the roller fixing points is particularly important for plastic guide rail or door module window regulators. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a roller bracket for automotive plastic guide rails or door module lifters to solve the risk of cracking and failure of the fixed position of the rollers of plastic guide rails or door module lifters.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A roller bracket for a car plastic guide rail or door module lifter includes a base plate, characterized in that: the base plate is provided with a roller bushing, a first support portion, and a second support portion; the roller bushing is located in the middle of the base plate; the first support portion and the second support portion are distributed vertically at the support ends of the base plate; the plastic guide rail or door module includes a base plate; the base plate is provided with a mounting base and a support wall plate; the roller bushing is fitted onto the mounting base; the roller is fitted onto the roller bushing; and the roller is connected to the mounting base by fastening screws; both the first support portion and the second support portion are supported and cooperate with the support wall plate.

[0005] The first support part is a support baffle formed by folding the bottom plate support end upward, and the second support part is a support claw formed by folding the bottom plate support end downward. There are two support claws, which are respectively located on both sides of the support baffle.

[0006] The substrate is provided with a clearance groove, which is in clearance fit with the second support portion.

[0007] The first support portion of the base plate is provided with a roller clearance groove at the root R-angle, and the roller clearance groove is matched with the roller clearance.

[0008] The back of the roller clearance groove is a raised structure, and the substrate corresponding to the raised structure is provided with clearance steps, which are in clearance cooperation with the raised structure.

[0009] The roller bracket is made of sheet metal.

[0010] The beneficial effects of this invention are that the improved automotive plastic guide rail or door module lifter roller bracket, with its support baffle and support claw, can provide effective structural support for the roller, ensuring that the roller can still maintain structural strength and stability under the tension of the steel wire rope, avoiding the risk of abnormal noise or even failure of the window lifting function due to large deformation or cracking of parts; the connection method of parts such as roller bracket, roller, plastic guide rail or door module base plate, and fastening screws is simple and easy to industrialize, and the compact structural design facilitates the spatial arrangement of various parts of the lifter.

[0011] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Figure 5 This is a schematic diagram of the interface structure between the plastic guide rail or door module substrate and the roller bracket of the present invention. Detailed Implementation

[0013] The accompanying drawings illustrate the structure of the present invention, and further details will be described below in conjunction with the drawings. In this embodiment, see the attached drawings. Figure 1-5The automotive plastic guide rail or door module lifter roller bracket 1 includes a base plate 1-4. The base plate 1-4 is provided with a roller bushing 1-1, a first support part 1-2, and a second support part 1-3. The roller bushing 1-1 is located in the middle of the base plate 1-4. The first support part 1-2 and the second support part 1-3 are distributed vertically at the support end of the base plate 1-4. The plastic guide rail or door module includes a base plate 4. The base plate 4 is provided with a mounting base 4-1 and a support wall plate 4-2. The roller bushing 1-1 is fitted onto the mounting base 4-1 to form a basic positioning. The roller 3 is fitted onto the roller bushing 1-1, and the roller 3 is connected to the mounting base 4-1 by fastening screws 2 to ensure a rigid connection between the roller 3 and the base plate 4. The first support part 1-2 and the second support part 1-3 are both supported and cooperated with the support wall plate 4-2.

[0014] As a further improved specific implementation, the first support part 1-2 is a support baffle formed by folding the support end of the base plate 1-4 upward, which abuts against the support wall plate of the substrate 4. The second support part 1-3 is a support claw formed by folding the support end of the base plate 1-4 downward. There are two support claws, which are respectively located on both sides of the support baffle and abut against the support wall plate 4-2 of the substrate 4. The support baffle and the support claw distributed vertically form a bidirectional support for the base plate 1-4, which counteracts the overturning moment generated by the tension of the steel wire rope of the roller 3, and avoids deformation or cracking of the installation position of the substrate 4.

[0015] As a further improved specific implementation, the substrate 4 is provided with a relief groove 4-4, which avoids interference with the second support part 1-3. The relief groove 4-4 provides installation space for the second support part 1-3.

[0016] As a further improved implementation, a roller clearance groove 1-5 is provided at the root R-angle of the first support portion 1-2 of the base plate 1-4. The roller clearance groove 1-5 is in clearance engagement with the roller 3 to prevent the roller 3 from colliding with the roller bracket 1 when rotating. The back of the roller clearance groove 1-5 is a raised structure, and a clearance step 4-3 is provided on the base plate 4 corresponding to the raised structure. The clearance step 4-3 is in clearance engagement with the raised structure to further optimize the spatial layout and ensure that the components operate without interference.

[0017] As a further improved implementation, the roller bracket 1 is made of sheet metal. While achieving weight reduction by using a plastic guide rail / door module, the rigid support of the metal bracket compensates for the insufficient strength of the plastic material, thus balancing weight reduction and structural reliability.

[0018] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
