Description

Technical Field

[0001] This utility model relates to the field of automotive display screen processing technology, specifically a fixing fixture for automotive display screen processing. Background Technology

[0002] With the rapid development of automotive intelligence, in-vehicle displays are trending towards larger sizes, curved surfaces, and irregular shapes, which places higher demands on their processing precision and assembly quality. In subsequent processing stages of the display, such as bezel finishing, circuit connection, or accessory installation, specialized fixtures must be used to securely and reliably fix it in place.

[0003] Most automotive display screen mounting fixtures on the market currently employ a single mechanical clamping method, such as using bolts or clips to secure the display screen. While this method can achieve some positioning of the display screen, it has significant limitations. Due to the diverse shapes and sizes of automotive displays, a single mechanical clamping method is insufficient to meet the mounting requirements of different specifications. Often, specialized fixtures need to be designed for different display screen models, which not only increases production costs but also reduces production efficiency. Furthermore, some fixtures exhibit uneven clamping force distribution when clamping the display screen, easily leading to excessive localized stress and deformation or damage; or, after prolonged use, the fixture components may wear down, causing a decrease in clamping force and affecting processing accuracy. Therefore, this paper proposes a mounting fixture for automotive display screen processing to address these issues. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 In this embodiment, a fixing fixture for processing automotive displays includes a base 1, and a fixing component for fixing is provided on the inner side of the base 1.

[0023] Please see Figure 1 In this embodiment, the fixing component includes a support plate 2 fixedly connected between the top and bottom walls of the base 1. A connecting cylinder 3 is rotatably connected to the inner side of the support plate 2. Threaded rods 4 are fixedly connected to both the left and right sides of the connecting cylinder 3. Threaded blocks 5 are threadedly connected to the outer side of the threaded rods 4. Fixing plates 6 are fixedly connected to both the front and rear sides of the threaded blocks 5. Connecting blocks 7 are fixedly connected between opposite sides of the front and rear fixing plates 6. Positioning airbags 8 are provided on opposite sides of the left and right connecting blocks 7.

[0024] The top of the connecting block 7 is provided with a reinforcing component to improve the fixing stability. The reinforcing component includes a connecting frame 9 fixedly connected to the top of the connecting block 7. A threaded sleeve 10 is fixedly connected to the inner side of the connecting frame 9. A threaded shaft 11 is threadedly connected to the inner side of the threaded sleeve 10. A positioning pressure plate 12 is rotatably connected to the bottom end of the threaded shaft 11.

[0025] Specifically, the top of the inner side of the connecting bracket 9 is provided with a fixing port that is compatible with the threaded sleeve 10, and the top of the threaded shaft 11 is fixedly connected with a torsion cap.

[0026] It should be noted that the threaded sleeve 10 is fixed to the fixing port of the connecting bracket 9 by laser welding to ensure stability under high torque transmission and prevent the threaded pair from loosening.

[0027] Specifically, a rubber layer 1201 is fixedly connected to the bottom of the positioning plate 12, and the size of the rubber layer 1201 is equal to the size of the positioning plate 12.

[0028] It should be noted that the rubber layer 1201 is made of high-friction coefficient silicone rubber material, and its surface is processed with anti-slip texture to increase the friction with the display screen surface, avoid scratching the workpiece surface when pressing, and at the same time provide uniform pressure distribution.

[0029] Specifically, a guide shaft 13 is fixedly connected to the top of the positioning plate 12, and a guide hole adapted to the guide shaft 13 is opened on the top of the inner side of the connecting frame 9.

[0030] It should be noted that the fit between the guide shaft 13 and the guide hole is a precision clearance fit to ensure that the positioning plate 12 does not wobble or shift during vertical movement.

[0031] Specifically, the air inlet of the positioning airbag 8 is fixedly connected to an air supply pipe 14, and the inner side of the connecting block 7 is provided with a receiving groove that is compatible with the air supply pipe 14.

[0032] Specifically, the left end of the left threaded rod 4 is rotatably connected to the inner left side wall of the base 1, and the right end of the right threaded rod 4 is rotatably connected to the inner right side wall of the base 1.

[0033] The working principle of the above embodiments is as follows:

[0034] Place the automotive display screen workpiece on the upper surface of the base 1, manually rotate the connecting cylinder 3 to drive the threaded rods 4 on both sides to rotate synchronously. Through the threaded pair transmission, the threaded blocks 5 on the left and right sides move towards or away from each other along the axial direction of the threaded rods 4, driving the fixed plate 6 and connecting block 7 to move. Adjust the gap between the positioning airbags 8 on both sides and the workpiece. Inflate the air supply pipe 14 through the external air source to make the positioning airbags 8 expand and tightly fit the side wall of the workpiece. Rotate the torsion cap to drive the threaded shaft 11 to move downward in the threaded sleeve 10. Through the guidance of the guide shaft 13 in the guide hole, ensure that the positioning pressure plate 12 presses down vertically. After the rubber layer 1201 contacts the top of the workpiece, it continues to apply pressure to form a vertical clamping force, which forms a multi-dimensional constraint with the side airbag fixation.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
