Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a fixing structure for a rear movable mounting guide rail of a glass on a new type of car door inner panel and a car door. Background Art

[0002] As Figure 4 shown, generally, a front glass guide rail 7 and a rear glass guide rail 2 are respectively arranged at the front end and the rear end of an existing automobile door glass 6. The cross sections of the front glass guide rail 7 and the rear glass guide rail 2 are in a U-shaped groove shape, and the corresponding edges of the glass are clamped in the corresponding U-shaped grooves, and the lifting of the door glass 6 is smoothly realized by using the guiding of the U-shaped grooves. When installing the door glass on the car door, generally, the door glass 6 is in a vertical state and the door glass 6 is located between the front glass guide rail 7 and the rear glass guide rail 2. Then, the door glass 6 is rotated by 90 degrees. Since the distance L1 between the front upper vertex angle and the rear lower vertex angle of the door glass 6 is larger than the distance L2 between the inner side walls of the front glass guide rail 7 and the rear glass guide rail 2, the door glass 6 cannot complete a 90-degree flip. Only the bolt 5 on the fixed support seat 3 at the lower part of the rear glass guide rail 2 can be disassembled, so that the lower part of the rear glass guide rail 2 can move backward by a certain distance. After the door glass 6 completes a 90-degree flip, then, the fixed support seat 3 is fixed on the car door inner panel 1 by using the bolt 5 again. When disassembling the door glass 6, a 90-degree rotation is also required, and the fixed support seat 3 at the lower part of the rear glass guide rail 2 also needs to be disassembled to realize the avoidance of the rear glass guide rail 2. The above installation and disassembly methods of the door glass 6 have the following defects:

[0003] 1. When disassembling and assembling the door glass 6, the guide rail bolt 5 needs to be removed again, and the bolt 5 is easy to be lost after being removed; 2. Repeated disassembly and assembly of the bolt 5 are likely to cause problems of thread damage; 3. Each time, the through hole on the fixed support seat 3 and the fixing hole on the car door inner panel 1 need to be aligned again, and the operation efficiency is low. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing structure for a rear movable mounting guide rail of a glass on a new type of car door inner panel and a car door. By using this fixing structure, the disassembly and reassembly of bolts are not required, and thus the disassembly and assembly efficiency of the door glass can be greatly improved.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a fixing structure for a rear movable mounting guide rail of a glass on a new type of car door inner panel, including a car door inner panel and a rear glass guide rail. The rear glass guide rail is arranged at the inner rear part of the car door inner panel. A fixed support seat is fixedly arranged at the lower part of the rear glass guide rail. The fixed support seat is connected with the car door inner panel, and the fixed support seat can slide back and forth and be positioned relative to the car door inner panel.

[0006] Preferably, the fixed support seat is L-shaped, and the fixed support seat is fixedly connected to the lower part of the rear glass guide rail by welding. A strip-shaped sliding groove corresponding to the fixed support seat is arranged on the inner door panel, and the strip-shaped sliding grooves are distributed in the front-back state. The fixed support seat is detachably arranged in the strip-shaped sliding groove.

[0007] Furthermore, a through hole corresponding to the strip-shaped sliding groove is arranged on the horizontal plate of the fixed support seat that fits the inner door panel. A bolt passes through the strip-shaped sliding groove and the through hole, and the horizontal plate is pressed and fixed on the inner door panel by using a nut sleeved on the bolt. The bolt can move freely back and forth in the strip-shaped sliding groove.

[0008] Furthermore, the front end of the strip-shaped sliding groove is inclined downward compared with the rear end.

[0009] Furthermore, the forward and backward movement distance of the bolt in the strip-shaped sliding groove is greater than the width of the rear glass guide rail in the front-back direction.

[0010] A vehicle door includes the fixed structure of the rear movable mounting guide rail of the inner door panel of the above-mentioned new type of vehicle door. The vehicle door further includes a door frame. The inner door panel is fixedly arranged inside the door frame, and a front glass guide rail corresponding to the rear glass guide rail is arranged inside the inner door panel.

[0011] The beneficial effects of the present invention are as follows: The structure of the present invention is simple and convenient for processing and manufacturing; by using the strip-shaped sliding groove arranged on the inner door panel, the fixed support seat can slide back and forth on the inner door panel. When the fixed support seat slides backward in place, the rear glass guide rail is adjusted to make way, thus facilitating the rotation of the vehicle door glass, and then improving the disassembly and assembly efficiency of the vehicle door glass; during the process of the fixed support seat making way and adjusting, only the bolt and the nut need to be kept loose, and there is no need to disassemble the bolt, so there is no problem of the bolt being disassembled and lost. At the same time, the phenomenon of bolt thread damage caused by disassembling the bolt is also greatly reduced; because the front end of the strip-shaped sliding groove is in an inclined downward state, it can realize the free sliding limit of the bolt in the strip-shaped sliding groove, thus ensuring that the rear glass guide rail cannot slide backward independently, preventing the occurrence of the phenomenon that the rear glass guide rail moves backward due to the attenuation of the bolt torque in the later stage, resulting in the derailment of the vehicle door glass.

[0019] Next, specific embodiments will be combined with the attached Figures 1-5 , the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some preferred embodiments of the present invention, rather than all embodiments. Those skilled in the art can make similar deformations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0020] The present invention provides a fixed structure for a novel rear movable mounting guide rail of the door inner panel glass (such as Figure 1As shown), it includes a door inner panel 1 and a glass rear guide rail 2, and the glass rear guide rail 2 is arranged at the inner rear part of the door inner panel 1. The door inner panel and the glass rear guide rail are both conventional technical structures on existing automobile doors, so the detailed structures of the door inner panel 1 and the glass rear guide rail 2 are not introduced in detail here. The glass rear guide rail 2 is mainly used to realize the lifting and guiding of the door glass 6. A fixed support seat 3 is fixedly arranged at the lower part of the glass rear guide rail 2. The fixed support seat 3 is connected to the door inner panel 1, and the fixed support seat 3 can slide back and forth and be positioned relative to the door inner panel 1. In actual applications, the forward and backward movement and positioning of the fixed support seat 3 can synchronously drive the forward and backward movement and positioning of the lower part of the glass rear guide rail 2, thereby ensuring the rotation adjustment and subsequent lifting and guiding of the door glass 6. By utilizing the left and right adjustment capability of the fixed support seat 3 on the door inner panel 1, the rearward displacement adjustment of the lower part of the glass rear guide rail 2 can be realized. After the rearward displacement adjustment of the lower part of the glass rear guide rail 2 is completed, the door glass 6 can be smoothly rotated 90 degrees between the glass front guide rail 7 and the glass rear guide rail 2, and then the door glass 6 can be straightened and installed. After the door glass 6 is rotated and straightened, the fixed support seat 3 is moved forward and fixed again, thereby ensuring that the glass front guide rail 7 and the glass rear guide rail 2 can guide the lifting and lowering of the door glass 6.

[0021] On the basis of the above embodiment, the specific implementation of the fixed support seat 3 is as follows: the fixed support seat 3 is L-shaped, the fixed support seat 3 is fixedly connected to the lower part of the glass rear guide rail 2 by welding, a strip slide groove 4 corresponding to the fixed support seat 3 is arranged on the door inner panel 1, and the strip slide groove 4 is distributed in a front-to-back state, and the fixed support seat 3 is arranged in the strip slide groove 4 in a detachable manner. Specifically, a through hole corresponding to the strip slide groove 4 is arranged on the horizontal plate 31 where the fixed support seat 3 and the door inner panel 1 are in contact. A bolt 5 passes through the strip slide groove 4 and the through hole, and the nut 51 sleeved on the bolt 5 is used to press and fix the cross plate 31 on the door inner panel 1. The bolt 5 can move freely forward and backward in the strip slide groove 4. In actual application, when the nut 51 is loosened, it is easy to slide the bolt 5 in the strip slide groove 4. Because the bolt 5 is not separated from the cross plate 31, the movement of the fixed support seat 3 is achieved while moving the bolt 5, and then the movement of the glass rear guide rail 2 is achieved. In this process, there is no need to disassemble the bolt 5.

[0022] When installing the door glass 6 using the present utility model, first pass the bolt 5 through the through holes of the strip-shaped chute 4 and the cross plate 31. Then, slip the nut 51 onto the end of the bolt 5 and rotate it two to three turns. After pre-installing the nut 51, hold the bolt 5 and slide it to the rear end of the strip-shaped chute 4. After sliding in place, rotate the door glass 6. After completing the rotation of the door glass 6, hold the bolt 5 again and slide it to the front end of the strip-shaped chute 4. After sliding in place, tighten the nut 51, thereby achieving the fixation of the lower part of the rear glass guide rail 2.

[0023] After using the strip-shaped chute 4 to realize the front-back movement adjustment of the bolt 5, in order to synchronously ensure the stability of the bolt 5 during positioning, here, the front end of the strip-shaped chute 4 is distributed obliquely downward compared to its rear end. The center horizontal height of the inclined front end 41 of the strip-shaped chute 4 is lower than the center horizontal height of the horizontal rear end 42 of the strip-shaped chute 4. The bolt 5 is kept at the position of the inclined front end 41 during positioning. The inclined front end 41 can be used to realize the free sliding limit of the bolt 5 in the strip-shaped chute 4, so as to ensure that the rear glass guide rail 2 cannot slide backward independently.

[0024] In practical applications, according to the size of the door glass 6, when rotating the door glass 6, in order to facilitate ensuring that the rear glass guide rail 2 can be effectively avoided, here, the front-back movement distance of the bolt 5 in the strip-shaped chute 4 is greater than the width of the rear glass guide rail 2 in the front-back direction (that is, the groove depth of the rear glass guide rail 2 plus the wall thickness of the guide rail). In this specific embodiment, the width of the rear glass guide rail 2 in the front-back direction is 15 mm, so the sliding distance of the bolt 5 in the strip-shaped chute 4 can be made 18 mm.

[0025] The present utility model also provides a door, including the fixing structure of the rear movable mounting guide rail of the inner panel glass of the above new type of door. The door further includes a door frame. The door inner panel 1 is fixedly arranged inside the door frame, and a glass front guide rail 7 corresponding to the rear glass guide rail 2 is arranged inside the door inner panel 1 in the front-back direction.

[0026] In the present utility model, "up", "down", "front", "rear", "left", and "right" are all relative positions used for conveniently describing the position relationship, so they cannot be understood as absolute positions to limit the protection scope.

[0027] Except for the technical features described in the specification, they are all known technologies to those skilled in the art.

[0028] The preferred embodiments and examples of the present utility model have been described in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments and examples. For those of ordinary skill in the art, without departing from the concept of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
