Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a vehicle window glass bracket. Background Art

[0002] Most car windows have a lifting function to adjust the transparency between the car and the outside world. The lifting function of the window requires the help of a lifting mechanism inside the car body or door. Since the window glass is relatively hard, direct contact with the metal traction end of the lifting mechanism will inevitably cause damage, so a bracket structure is needed to disperse the stress. The existing bracket structure is connected to the window glass by plugging, and is connected to the traction end of the lifting mechanism by bolts. Since the contact area between the bracket and the bolt is relatively small, when the window is squeezed, such as by water pressure, the lifting mechanism forcibly pulls the bracket, and it is very likely to break the bolts and lose control of the window. Therefore, the manufacturer will limit the upper limit of the traction force of the lifting mechanism. When the vehicle is submerged in water with the windows closed, it is even more impossible to open the window by electric drive. Summary of the invention

[0003] The purpose of the present application is to provide a safer and more reliable vehicle window glass bracket.

[0004] In order to achieve the above purpose, the present application provides a vehicle window glass bracket: comprising a traction part, the upper end of which is fixedly connected to a first limiting part and a second limiting part through a bridging part, a fitting groove is formed between the first limiting part and the second limiting part, the traction part is provided with a first through hole and a second through hole, the traction part is provided with an embedded nut in the first through hole, and the traction part is provided with a bushing in the second through hole, which can disperse the pressure on the embedded nut.

[0005] Preferably, the first through hole passes through the two end surfaces of the traction portion with the largest area, a spline groove is formed on the inner wall of the first through hole, and the outer side surface of the embedded nut has a spline petal suitable for tightly fitting with the spline groove to limit relative movement.

[0006] Preferably, the embedded nut is provided with a coaxial internal screw hole, the internal screw hole passes through both end surfaces of the embedded nut, and the embedded nut is located at the central position of the traction part, so that the center of gravity of the bracket is close to the symmetrical position.

[0007] Preferably, the inner wall of the second through hole is smooth and suitable for close contact with the outer side surface of the bushing. The wall thickness of the bushing is uniform. There are two bushings, which are respectively located on the left and right directions of the embedded nut, so that the bracket has a more symmetrical structure. The directional selection during installation can be more arbitrary, which is conducive to improving assembly efficiency.

[0008] As a preferred embodiment, the embedded nut and the bushing are both made of corrosion-resistant alloy material to ensure the stability of the shapes of the embedded nut and the bushing.

[0009] As a preference, both ends of the embedded nut and the bushing are located between the two end surfaces of the traction portion to avoid hard contact and wear between the embedded nut and the bushing, which are also made of metal materials, and the lifting component.

[0010] Preferably, the first limiting portion is parallel to the opposite side of the second limiting portion, and the first limiting portion and the second limiting portion are provided with a shallow glue groove and a deep glue groove on the opposite side, that is, the inner side wall of the fitting groove, which is suitable for filling elastic curing glue between the vehicle window glass, and can effectively disperse and absorb stress and vibration.

[0011] Preferably, a first rib is provided between one end surface of the traction portion and the lower surface of the bridging portion, and a second rib is provided between the other end surface of the traction portion and the lower surface of the bridging portion, for improving the posture stability of the two limiting plates.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By additionally providing a bushing structure on the traction part of the bracket, the pressure of the bolts on the embedded nut and the lifting drive can be effectively dispersed, so that the glass bracket can withstand a greater force to push up or pull down the window glass, and the traction force of the window lifting mechanism can be further improved. In the case that the circuit has not failed, even if the window is in a closed state and sinks into the water, it can be opened by electronic control. Therefore, the bracket has higher safety and reliability;

[0014] (2) By filling the deep and shallow glue grooves with cured glue, the bracket and the window glass can withstand greater pulling force, providing stable traction guarantee for opening the vehicle window in water. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] like Figure 1-5The vehicle window glass bracket shown in the figure comprises a traction part 1 with a small lower end and a large upper end. The traction part 1 has a uniform thickness and is in an inverted isosceles trapezoid. The traction part 1 is provided with a first through hole 101 and a second through hole 103. The first through hole 101 passes through the two end surfaces of the traction part 1 with the largest area and is located at the center of the traction part 1. The traction part 1 is provided with an embedded nut 6 in the first through hole 101, so the embedded nut 6 is also located at the center of the traction part 1. The embedded nut 6 is made of a corrosion-resistant alloy material, and the material is usually selected from S20 to 35C, and the material is The material must not contain Pb, Hg, and +6-valent Cr ions, and the surface is treated with MFZn2-B. The inner wall of the first through hole 101 is provided with a spline groove 102, and the outer side surface of the embedded nut 6 has a spline petal 602 that fits tightly with the spline groove 102. In fact, the spline groove 102 is forced to form by the cavity formed by the spline petal 602 during the injection molding process of the traction part 1. The embedded nut 6 is provided with a coaxial internal screw hole 601, and the same internal screw hole 601 also runs through the two end faces of the embedded nut 6, which is convenient for observing the screw-in depth of the mating bolt.

[0026] The traction part 1 is provided with a bushing 7 in the second through hole 103. The bushing 7 is also made of corrosion-resistant alloy material and is consistent with the material of the embedded nut 6. The inner wall of the second through hole 103 is smooth and can be in close contact with the outer side of the bushing 7. The second through hole 103, like the first through hole 101, is also formed by the cavity constraint formed on the outer surface of the bushing 7 during the injection molding process of the traction part 1. The wall thickness of the bushing 7 is uniform, which is convenient for processing and molding. In this embodiment, there are two bushings 7, which are respectively located in the left and right directions of the embedded nut 6, and the axes of the two bushings 7 are at the same height, which is higher than the axis of the embedded nut 6. It should be noted that both ends of the embedded nut 6 and the bushing 7 are located between the two end faces of the traction part 1, that is, the embedded nut 6 and the bushing 7 cannot protrude from the end face of the traction part 1. Under normal circumstances, the end faces of the embedded nut 6 and the bushing 7 are sunk into the end face of the traction part 1 by 0 to 0.2 mm.

[0027] The upper end of the traction part 1 is fixedly connected with the first limiting part 3 and the second limiting part 4 through the bridging part 2. The first limiting part 3 and the second limiting part 4 are mirror images of each other. A first rib 201 is provided between one end face of the traction part 1 and the lower surface of the bridging part 2. The first rib 201 has one piece and is located at the center of the lower surface of the bridging part 2. A second rib 202 is provided between the other end face of the traction part 1 and the lower surface of the bridging part 2. The second rib 202 has two pieces and are symmetrical about the first rib 201. In fact, the traction part 1, the first rib 201, the second rib 202, the first limiting part 3 and the second limiting part 4 are an integrated structure, which is injection molded by PBT material in one step.

[0028] A fitting groove 5 is formed between the first limiting portion 3 and the second limiting portion 4, which can be embedded in the vehicle window glass. Usually, the lower edge of the vehicle window glass is embedded in the fitting groove 5 and completely sunk to the bottom to contact the upper surface of the bridge portion 2. The first limiting portion 3 and the second limiting portion 4 are parallel to the opposite sides, which are consistent with the thickness of the vehicle window glass to be matched. The first limiting portion 3 and the second limiting portion 4 are on the opposite sides, that is, the inner side walls of the fitting groove 5 are provided with a shallow glue groove 501 and a deep glue groove 502, which are suitable for filling elastic curing glue between the vehicle window glass. As the name implies: the shallow glue groove 501 is shallower than the deep glue groove 502 in the direction perpendicular to the two limiting plates, but both are used to increase the connection with the solid The contact area of ​​the curing glue is just a little larger, but the deep glue groove 502 will have a larger contact area with the curing glue in the depth direction, which can effectively suppress the window glass from moving along the horizontal length direction parallel to the two limit plates; and in this embodiment, the shallow glue groove 501 is divided into two groups closer to the left and right ends of the limit plate, and the deep glue groove 502 is located between the shallow glue grooves 501 on both sides. Since the shallow glue groove 501 is formed by cutting the inner wall of the limit plate on the basis of the deep glue groove 502, more curing glue can be filled near the shallow glue groove 501, and the thickness of the curing glue is larger. Since the curing glue has a certain elasticity, it can better absorb the impact of the relative swing of the bracket and the window glass.

[0029] Working principle: During installation, first tighten the embedded nut 6 onto the liftable bolt of the drive assembly. After tightening, apply a reverse force of 15 N·m to the embedded nut. If there is no loosening or cracking, it means that the embedded nut 6 is stably connected to the lifting screw. Then let the shaft body that cooperates with the guide rail in the car door pass through the bushing 7. The shaft body is also connected to the lifting end of the drive assembly to disperse the stress of the liftable bolt. In this way, the entire bracket is restricted by the bolt and the shaft body and cannot rotate. Then insert the car window glass into the open fitting groove 5 at the upper end until the lower edge of the car window glass abuts the bridge part 2. Finally, inject the elastic colloid after curing along the shallow glue groove 501 and the deep glue groove 502. After waiting for the colloid to bond and cure, test its bonding force at room temperature to be ≥1000N, that is, the connection can withstand a force of 100 kg and last for more than 10 minutes without falling off, indicating that the bracket connection is qualified.
