TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a frameless door glass mounting structure, a door assembly and a vehicle. BACKGROUND

[0002] Frameless door refers to a type of door without a complete metal frame, usually without an upper frame (no frame at the door glass). This design allows the door glass to slide directly into the side of the vehicle body (the glass will automatically lower when the door is opened, and automatically rise to close after closing), thereby creating a more smooth and dynamic visual effect, while also reducing the A-pillar blind area and optimizing the driver's view.

[0003] However, since the door does not have an upper frame, the door glass cannot be connected with the fixed frame during installation, but is fastened to the lifter inside the door and is fixed relative to the door. The through hole on the lifter for fastening the door glass has a large size, and the door glass will shake. Currently, an assembly tool with X, Y and Z positioning devices is usually used to adjust the fixed position of the door glass relative to the lifter. By adjusting the position of the door glass through the moving mechanism and positioning components in three directions, the positioning accuracy of the door glass can be improved. However, during mass production, the number of products is large, and each door glass needs to be adjusted and positioned in three directions, which is complex and time-consuming, affecting production efficiency. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application aims to provide a mounting structure suitable for frameless door glass installation, which can quickly position the door glass in the appropriate position of the mounting hole, and does not require the operator to adjust and position each door glass in three directions, thereby simplifying the positioning operation, shortening the installation time, and improving the production efficiency without affecting the installation accuracy of the door glass.

[0023] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0024] The installation of frameless door glass is usually carried out by a mounting tool capable of fixing the door, which comprises a component for fixing the door, a three-way moving mechanism for adjusting the glass, a detection component for detecting the position of the door glass, etc. In actual use, the door glass is first pre-placed on the lifter of the door, such as the mounting slot or support seat on the sliding block, but has not yet been aligned and fastened. When the door with the pre-installed glass moves to the mounting tool, the mounting tool acquires the door and fixes it to a preset position on the tool, and then acquires the glass and the operator adjusts the attitude of the glass in the X, Y and Z directions, so that the glass abuts against the positioning members in the three directions respectively, and determines whether the glass is installed in place (the mounting tool frame) through the feedback of the detector (the positioning member position of the glass and the preset position of the door are associated, and the ideal size in the installed vehicle model is determined according to the size of the vehicle model, so when the door is fixed to the preset position and the glass is adjusted to abut against the positioning member, the surface glass is in the appropriate position). At this time, the operator installs the bolt to fasten the glass to the sliding block of the lifter, and the installation of the frameless door glass is completed. Through the above positioning adjustment, the frameless door glass is installed with good position accuracy, and after the door is installed on the vehicle, the glass can be seamlessly closed with the door frame.

[0025] However, each installation of frameless door glass requires the operator to make detailed adjustments through the tool, which is time-consuming, and the production efficiency needs to be improved when the vehicle is produced in batches. In view of this, please refer to the attached Figures 1-4 The embodiment of the present application provides a frameless door glass mounting structure, which aims to simplify the positioning operation of the door glass and improve the production efficiency without affecting the positioning and installation accuracy of the door glass.

[0026] The mounting structure comprises a lifter 1, a door glass and a positioning insert 3 arranged on the lifter 1. The lifter 1 comprises a sliding block 2 for driving the door glass to lift, and the sliding block 2 is provided with a mounting hole 201, and the door glass is fixed to the sliding block 2 by means of a bolt inserted into the mounting hole 201. The positioning insert 3 is used to fill in the mounting hole 201, and is used to fill the excess space of the mounting hole 201 which is wider than the bolt. The positioning insert 3 is provided with a positioning groove 301 for embedding the bolt, and the positioning groove 301 and the remaining space of the mounting hole 201 form a tight positioning hole 302 for the bolt to pass through. Preferably, the positioning groove 301 is an arc-shaped groove, which can also be regarded as a positioning hole with a side opening. In this way, after the positioning insert 3 is embedded in the mounting hole 201, the remaining space is small, forming a tight positioning hole 302, and the size of the tight positioning hole 302 is basically matched with the diameter of the bolt, which is the installation position of the bolt. After the bolt is inserted, it will not shake too much, and can accurately fix the door glass.

[0027] The size and filling position of the positioning insert 3 are determined in advance based on the theoretical dimensions of the vehicle model or vehicle with the door glass already installed (similar to the positioning process of the positioning parts on the installation fixture in the prior art). For example, if the position is set according to the door glass installed on a tested and stable vehicle model, the size and filling position of the positioning insert 3 are also very precise. After it fills into the mounting hole 201 on the slider 2, it eliminates the interference space of the mounting hole 201, leaving only a small space that matches the bolt size, i.e., the tight positioning hole 302. This hole is the precise bolt insertion position. In this way, in the mass production of vehicles, only a few vehicles need to be installed first using the door glass installation fixture. Then, after determining the positioning insert 3 based on the already installed vehicle model, the positioning insert 3 can be applied to the assembly of subsequent vehicles. For example, the positioning insert 3 can be directly filled into the slider 2 of the lifter 1 of the subsequent vehicle and fixed by bonding or welding. After that, the door glass can be quickly and directly installed without the need for XYZ three-axis attitude adjustment and detailed inspection of each door glass, which can effectively improve production efficiency.

[0028] As can be seen, the installation structure provided in this application, by setting a positioning insert 3 to fill the slider 2 of the lifter 1 (the position and size of the positioning insert 3 can be determined according to the position of an already installed door glass and slider 2, and then applied in subsequent mass production), allows the positioning insert 3 to fill the interference space of the mounting hole 201. The small space enclosed by the positioning groove 301 and the mounting hole 201 is the precise installation point of the door glass and also the bolt fastening point. Directly tightening the bolts can fix the door glass in the precise installation position. In this way, without affecting the positioning accuracy of the door glass, the positioning insert 3 can eliminate the complicated operation of adjusting the position of the door glass through tooling, which is very suitable for the mass installation of door glass in mass production and can improve production efficiency.

[0029] In actual production, the installation position of the door glass may vary for different batches and models of vehicles. Therefore, the positioning insert 3 is matched with the vehicle model. One positioning insert 3 is set according to one or a batch of vehicle models, so there are multiple positioning inserts 3. Different batches or different models of vehicles have different positioning inserts 3.

[0030] Preferably, the shape of the positioning insert 3 matches the mounting hole 201, such as... Figure 3 As shown, the position of the positioning groove 301 on the positioning insert 3 is determined according to actual needs. It can be located in the middle of the positioning insert 3 or in a position slightly off the periphery of the middle of the positioning insert 3. For example, the positioning groove 301 is set in the middle of the positioning insert 3 and has a through hole structure; or, the positioning groove 301 is recessed inward from the edge of the positioning insert 3, and the groove is formed at the edge of the positioning insert 3.

[0031] In this way, the outer contour size of the positioning insert 3 and the filling position in the mounting hole 201 can be basically the same on different car models. Only the position of the positioning groove 301 can be adjusted according to different car models and different installation positions of the door glass, which makes it easier to mass-produce the positioning insert 3.

[0032] The positioning groove 301 is preferably an arc-shaped groove with an arc-shaped inner wall. The diameter of the arc-shaped groove is matched with the diameter of the bolt. This allows for a closer fit to the bolt and prevents bolt wobble.

[0033] When the positioning groove 301 is an arc-shaped groove that is recessed into the block body from the edge of the positioning insert 3, the groove is formed at the edge of the positioning insert 3. The size of the groove (referring to the straight distance from the groove wall on one side of the groove to the groove wall on the other side of the groove) can be less than the diameter of the bolt, or it can be greater than or equal to the diameter of the bolt.

[0034] In some embodiments, the mounting hole 201 is a square hole, including four straight sides and four curved corner areas; the shape of the positioning insert 3 matches the mounting hole 201, and is a square with slots and corner areas. Therefore, after the positioning insert 3 fills into the mounting hole 201, it is positioned and fitted against the mounting hole 201, providing a circumferential anti-rotation positioning connection effect. The positioning insert 3 will not rotate within the mounting hole 201, and the position of the set compression positioning hole 302 will not deviate. If the mounting hole 201 is a circular hole and the positioning insert 3 is a circular block, then when the positioning insert 3 is inserted into the mounting hole 201, the positioning insert 3 is prone to relative rotation, causing a deviation in its position within the mounting hole 201.

[0035] When both the mounting hole 201 and the positioning insert 3 are square, preferably, the groove of the circumferential positioning groove 301 is located in the corner area of ​​the positioning insert 3, and is used to enclose the corner area of ​​the mounting hole 201 to form a tightening positioning hole 302. In this way, not only is the positioning groove 301 an arc-shaped groove, but the inner wall of the mounting hole 201 enclosed by it is also an arc-shaped surface, so the entire tightening positioning hole 302 can be a relatively regular through hole, which better matches the bolt.

[0036] In such embodiments, such as Figure 1 As shown, the size of the slot can be basically equal to or slightly larger than the diameter of the (interference fit) bolt; thus, it is very convenient for the bolt to be inserted, and it is also convenient to form a relatively regular through hole with the corner area of ​​the mounting hole 201.

[0037] In some embodiments, the outer wall of the positioning insert 3 is used to fit against the wall of the mounting hole 201, and the outer wall of the positioning insert 3 and / or the inner wall of the positioning groove 301 are covered with elastic pads to provide position adjustment for tightening the positioning hole 302.

[0038] In the actual assembly process, after the door glass is fixed by penetrating the bolt into the compression positioning hole 302, the position of the door glass can be detected by a detector or a measuring ruler. If the door glass needs to be fine-tuned due to processing errors, installation errors, and other factors on part of the vehicle, the adjustment amount is very small, and then the operator can directly fine-tune the glass through detection information, so that the bolt extrudes the elastic soft pad in the compression positioning hole 302 or extrudes the elastic soft pad between the positioning insert 3 and the mounting hole 201 to fine-tune the position. It can be seen that the elastic soft pad provided on the positioning insert 3 can adapt to the installation error, better meet the installation requirement, and improve the practicability. Moreover, the thickness of the elastic soft pad is thin, and the compression amount is small, so as not to affect the positioning accuracy of the door glass during installation of the door glass.

[0039] Specifically, the elastic soft pad is a silica gel pad or a rubber pad. The thickness of the elastic soft pad can be 0.5-1 mm.

[0040] The body of the positioning insert 3, i.e., the block, can be injection molded, and is an integral injection molded part. In this way, the positioning insert 3 can be quickly produced and has accurate dimensions. The elastic soft pad can be bonded to the block or can be formed on the positioning insert 3 by secondary injection molding.

[0041] Alternatively, in some embodiments, the block of the positioning insert 3 is provided with a sliding groove at the positioning groove 301, and an arc-shaped cover plate connected in the radial direction is embedded in the sliding groove, and the arc-shaped cover plate forms the groove wall of the positioning groove 301.

[0042] Meanwhile, an elastic member is also arranged in the sliding groove and abuts against the inner side of the arc-shaped cover plate. In this way, the arc-shaped cover plate can also have an adjustment amount in the radial direction, and can also serve the purpose of fine-tuning the posture or position of the bolt after detection.

[0043] The embodiments of the present application also provide a vehicle door assembly, which comprises a door, a lifter 1, and door glass, and is provided with the frameless door glass mounting structure as described in any of the above embodiments.
