Description

Technical Field

[0001] This utility model relates to the field of HUD display, and more particularly to a backlight TFT bracket for AR-HUD display devices. Background Technology

[0002] As a core interactive component of automotive smart cockpits, AR-HUD requires high-definition image display and information projection through a backlit TFT screen, which places extremely stringent requirements on the structural stability, ease of disassembly and assembly, and adaptability of the backlit TFT bracket.

[0003] In existing AR-HUD backlight TFT brackets, during actual installation, the TFT screen needs to be placed in the limiting protrusion on the upper side of the bracket before the TFT cover is directly snapped on. The buckle design between the TFT cover and the TFT bracket secures the TFT screen. However, during subsequent maintenance and disassembly, workers need to insert tools into the gap between the TFT bracket and the TFT cover to forcibly pry the buckle. This not only limits the operating space and makes it difficult to apply force, but also easily leads to the buckle breaking or the bracket body cracking, or even scratching the surface of the TFT screen or damaging the backlight assembly. Furthermore, the buckle-type fixation relies too much on the elastic deformation of the buckle to generate clamping force. After long-term use or repeated maintenance, the buckle is prone to elastic fatigue, resulting in a decrease in clamping force and slight loosening between the TFT screen and the cover. This can cause the backlight assembly's optical path to shift, resulting in problems such as ghosting and uneven brightness in the AR-HUD display image, affecting the driver's information reading experience and even posing safety hazards.

[0004] Therefore, it is necessary to provide a new backlight TFT bracket for AR-HUD display devices to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a backlight TFT bracket for an AR-HUD display device.

[0006] This utility model provides a backlight TFT bracket for an AR-HUD display device, comprising: a bracket base, on both sides of which are fixedly connected side mounting ears; a limiting protrusion on the upper side of the bracket base, with a through opening at the center of the limiting protrusion; and a quick-release mechanism, comprising two rear seats, with a mating seat between the two rear seats; pins on both sides of the mating seat; a clamping frame fixedly connected to the mating seat; a front block on the front wall of the clamping frame; and an opposing block at the front end of the bracket base, with a locking component in the opposing block.

[0007] Preferably, the two rear seats are symmetrically arranged, and each of the two rear seats has a shaft hole on the side wall of the opposite side, and the two pins are rotatably connected to the two shaft holes respectively.

[0008] Preferably, the inner wall of the pressing frame is provided with multiple pressing plates, and the multiple pressing plates are arranged symmetrically in pairs.

[0009] Preferably, the locking assembly includes an embedded tube, the opposing block has a locking groove, one side wall of the locking groove has an installation port, the embedded tube is fixedly installed in the installation port, a locking rod is slidably connected in the embedded tube, a spring is sleeved on the locking rod, and a lever is fixedly connected to one end of the locking rod.

[0010] Preferably, the lower end of the front block is provided with a through-hole, and the locking rod is aligned with the through-hole.

[0011] Preferably, a limiting plate is fixedly connected to the clamp rod, the limiting plate is located inside the inner tube, one end of the spring is connected to the limiting plate, and the other end of the spring is connected to the tube wall of the inner tube.

[0012] Compared with related technologies, the backlight TFT bracket for AR-HUD display devices provided by this utility model has the following beneficial effects:

[0013] 1. This utility model rotates the docking seat upward around the pin axis, causing the clamping frame to rotate synchronously to the position covering the TFT top cover. When this happens, multiple symmetrical pressure plates on the inner wall of the clamping frame are tightly attached to the surface of the TFT top cover. The pressure of the multiple pressure plates forms a vertical clamping force on the TFT top cover, preventing loosening between the TFT top cover and the TFT screen. With the rotatable and fastened clamping frame and subsequent locking components, when the TFT screen is being repaired, the operator does not need to insert tools or fingers into the narrow gaps of the clips to pry them open. Separation can be achieved quickly, effectively solving the problems of limited operating space, difficulty in applying force, or clip breakage or damage to the bracket body due to improper force.

[0014] 2. This utility model uses a pull tab to drive the locking rod to slide, so that one end of the locking rod slides into or away from the through-hole at the lower end of the front block, thereby achieving rigid locking and separation of the front block and the opposing block. Compared with the traditional built-in snap-on bracket, the installation operation time of this bracket is shorter, which not only significantly improves the assembly efficiency, but also facilitates the quick disassembly and maintenance of subsequent staff. It is especially suitable for the mass production and maintenance of AR-HUD display devices. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 3 A backlight TFT bracket for an AR-HUD display device includes: a bracket base 1, with side mounting ears 2 fixedly connected to both side walls of the bracket base 1, a limiting protrusion 3 on the upper side of the bracket base 1, and a through opening 31 at the middle position of the limiting protrusion 3; and a quick-release mechanism, including two rear seats 4, with a docking seat 41 between the two rear seats 4, pins 42 on both side walls of the docking seat 41, a clamping frame 411 fixedly connected to the docking seat 41, a front block 43 on the front wall of the clamping frame 411, and an opposing block 44 at the front end of the bracket base 1, with a locking component in the opposing block 44.

[0021] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the two rear seats 4 are symmetrically arranged, and each of the two rear seats 4 has a shaft hole on the side wall on the opposite side. The two pins 42 are rotatably connected to the two shaft holes respectively.

[0022] It should be noted that after the operator completes the initial assembly of the TFT screen and the top cover, the docking seat 41 can be rotated upward around the pin 42, which will drive the clamping frame 411, which is fixedly connected to the docking seat 41, to rotate synchronously. When the clamping frame 411 rotates to the position covering the TFT top cover, it can prevent the TFT top cover and the TFT screen from becoming loose. With the rotatable and fastened clamping frame 411 and subsequent locking components, when the TFT screen is being repaired, the operator does not need to put tools or fingers into the narrow gaps of the clips to pry them open. Separation can be achieved quickly, which effectively solves the problems of limited operating space, difficulty in applying force, or clip breakage or damage to the bracket body due to improper force.

[0023] refer to Figure 1 As shown, multiple pressure plates are provided on the inner wall of the clamping frame 411, and the multiple pressure plates are arranged symmetrically in pairs.

[0024] It should be noted that the pressure of multiple pressure plates is used to form a vertical clamping force on the TFT top cover to prevent loosening between the TFT top cover and the TFT screen.

[0025] The symmetrical arrangement of multiple pressure plates in pairs ensures that the clamping force on the TFT cover is evenly distributed across multiple symmetrical points. This prevents deformation of the TFT cover due to excessive local force or loosening between the TFT screen and the cover due to uneven force, thereby ensuring the stability of the optical path during AR-HUD display and avoiding problems such as image ghosting and uneven brightness.

[0026] refer to Figure 2 and Figure 3 As shown, the locking assembly includes an inner tube 5, a locking groove in the opposing block 44, an installation port on one side wall of the locking groove, the inner tube 5 is fixedly installed in the installation port, a locking rod 6 is slidably connected in the inner tube 5, a spring 61 is sleeved on the locking rod 6, and a paddle 62 is fixedly connected to one end of the locking rod 6.

[0027] It should be noted that: pulling the lever 62 causes the locking lever 6 to slide, and one end of the locking lever 6 slides away from the through-hole at the lower end of the front block 43, thereby unlocking the front block 43 and the opposing block 44.

[0028] The lever 62 extends outward from the opposing block 44, providing the operator with a convenient point of force application. The lever 6 can be moved by turning the lever 62 without the need for tools, thus improving the ease of operation.

[0029] refer to Figure 1 and Figure 2 As shown, a through-hole is provided at the lower end of the front block 43, and the locking rod 6 is aligned with the through-hole.

[0030] It should be noted that the locking rod 6 is aligned with the through-hole to avoid the locking rod 6 being unable to be inserted or becoming loose after insertion due to positional deviation. The inner diameter of the through-hole is adapted to the outer diameter of the locking rod 6, which can ensure the smooth insertion of the locking rod 6 and ensure that there is no obvious shaking between the locking rod 6 and the through-hole after insertion, so as to achieve a rigid connection between the front block 43 and the opposing block 44, thereby stabilizing and fixing the clamping frame 411 in the clamping position.

[0031] refer to Figure 3 As shown, a limiting disk 7 is fixedly connected to the lever 6. The limiting disk 7 is located inside the inner tube 5. One end of the spring 61 is connected to the limiting disk 7, and the other end of the spring 61 is connected to the tube wall of the inner tube 5.

[0032] It should be noted that: the limiting plate 7 can limit the sliding stroke of the locking rod 6, prevent the locking rod 6 from completely dislodging from the inner tube 5, and ensure the structural integrity of the locking assembly;

[0033] On the other hand, the limiting plate 7 provides a stable force carrier for the spring 61. When the lever 62 is moved to drive the locking rod 6 to move, the limiting plate 7 moves synchronously and compresses the spring 61, so that the spring 61 stores elastic potential energy.

[0034] After the lever 62 is released, the spring 61 converts the elastic potential energy into a force that pushes the locking rod 6 back to its original position through the limiting plate 7, thereby realizing the function of automatically inserting the locking rod 6 into the through-hole without the need for manual pushing of the locking rod 6, simplifying the operation steps and improving assembly efficiency.

[0035] The working principle of the backlight TFT bracket for AR-HUD display device provided by this utility model is as follows: First, the TFT screen is placed in the limiting protrusion 3 on the upper side of the bracket 1. The limiting protrusion 3 uses its own frame structure to form a circumferential limit on the TFT screen to prevent the TFT screen from shifting horizontally in subsequent operations. Then, the TFT top cover is placed so that the TFT top cover covers the TFT screen, completing the initial assembly of the TFT screen and the top cover.

[0036] The operator can rotate the docking seat 41 upward around the pin 42, which will drive the clamping frame 411, which is fixedly connected to the docking seat 41, to rotate synchronously. When the clamping frame 411 rotates to the position covering the TFT top cover, multiple symmetrical pressure plates on the inner wall of the clamping frame 411 are tightly attached to the surface of the TFT top cover. The pressure of the multiple pressure plates forms a vertical clamping force on the TFT top cover, preventing the TFT top cover from becoming loose from the TFT screen.

[0037] During the rotation of the clamping frame 411, the front block 43 at its front end moves synchronously with the clamping frame 411. When the clamping frame 411 completely covers the TFT top cover, the front block 43 moves to the alignment position with the opposing block 44 at the front end of the bracket 1. At this time, pulling the lever 62 causes the locking rod 6 to slide. Then, releasing the lever 62 causes the spring 61 to return to its elastic deformation, allowing one end of the locking rod 6 to reset and insert into the through-hole at the lower end of the front block 43, achieving rigid locking between the front block 43 and the opposing block 44. This fixes the clamping frame 411 in the clamping position, completing the entire installation and fixing process of the TFT screen and the top cover. This not only effectively shortens the installation steps of the TFT screen but also facilitates subsequent maintenance work on the TFT screen.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
