Description

Technical Field

[0001] This invention relates to the field of screen support technology, specifically to a vehicle-mounted screen support component and a vehicle-mounted screen. Background Technology

[0002] With the popularization of car culture and the rise of lifestyles such as outdoor camping and self-driving tours, in-vehicle projection systems have become an important piece of equipment for enhancing outdoor entertainment experiences. Among these systems, the stability and flatness of the screen, as the carrier of the projected image, directly determine the final viewing quality. The in-vehicle screen bracket, as a key component connecting the vehicle and the screen, has seen its technological evolution directly reflect changes in user needs.

[0003] Existing methods for fixing vehicle-mounted screens have the following limitations:

[0004] Some telescopic and folding brackets designed specifically for certain car models or screens have appeared on the market. While these brackets offer a certain degree of stability, they lack fixed support points, making them prone to instability. Furthermore, the length of the crossbars or the spacing of the fixing claws are mostly fixed or only slightly adjustable, making them incompatible with screens of varying widths. In addition, to address versatility, users may use makeshift support rods and numerous straps. While this method can secure various screens, it suffers from cumbersome installation, poor stability, susceptibility to wind, and inconvenient storage.

[0005] Therefore, it is necessary to develop and design vehicle-mounted screen support components and vehicle-mounted screens. Ensuring the stability of the screen support while improving the applicability to different screen sizes is a technical problem that urgently needs to be solved by those skilled in the art.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The purpose of this invention is to provide a vehicle-mounted screen support component and a vehicle-mounted screen, which improves applicability to different screen sizes while ensuring stable screen support.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] refer to Figure 1 and Figure 3 The vehicle-mounted screen support disclosed in this embodiment of the invention includes at least a bottom connector, which is connected to the trunk latch. A bottom bracket assembly 3 is hinged on the bottom connector. A screen connector for connecting the screen 2 is provided at the end of the bottom bracket assembly 3 away from the bottom connector. The bottom bracket assembly 3 includes at least two telescopic rods 14, which are hinged to the bottom connector. The spacing between adjacent telescopic rods 14 is adjustable. The standardized connection between the bottom connector and the trunk latch enables quick and stable installation. Combined with the hinged design of the bottom bracket assembly 3 and the adjustable spacing of the telescopic rods 14, the support can flexibly adapt to screens 2 of different sizes, suspension methods, and tensions. While ensuring the stability of the screen 2 support, it achieves high compatibility, convenient adjustment, and compact storage for various screens 2, significantly improving the outdoor applicability and user experience of the vehicle-mounted screen.

[0029] refer to Figure 1 and Figure 3In one embodiment, the bottom connector includes a bracket fixing seat 11. A hinge is provided at the end of the bracket fixing seat 11, which is hinged or fixedly connected to the end of the telescopic rod 14. A through groove is provided on the side of the bracket fixing seat 11, and a bracket fixing buckle 8 is provided inside the through groove. A buckle receiving groove for accommodating a trunk latch is also provided on the bracket fixing seat 11. The extension direction of the buckle receiving groove is perpendicular to the extension direction of the through groove, i.e., the buckle receiving groove and the through groove form a cross-shaped hole. A fixing push button assembly is sleeved on the outside of the bracket fixing seat 11. The fixing push button assembly can slide along the extension direction of the buckle receiving groove. A U-shaped groove is provided at the end of the fixing push button assembly that mates with the trunk latch. Two bracket fixing buckles 8 are provided and are arranged opposite each other. Within the latch receiving groove, positioned between two bracket fixing buckles 8, the sliding of the fixing push button assembly allows for the opening and closing of the ends of the two bracket fixing buckles 8, thereby achieving the locking and releasing of the trunk latch. Through the slidable arrangement of the bracket fixing seat 11 and the fixing push button assembly, a highly efficient trigger-type locking mechanism is formed. By simply pushing the push button, the two opposing bracket fixing buckles 8 inside can be linked to achieve automatic clamping and locking or releasing of the trunk latch, realizing one-button tool-free connection with the vehicle. At the same time, the vertical cross design of the latch receiving groove and the U-shaped groove ensures that the trunk latch is subjected to multi-directional constraints when clamped, significantly enhancing its resistance to torsion and pull-out, and keeping the bracket absolutely stable when the vehicle vibrates or the curtain 2 is exposed to wind.

[0030] It should be noted that the hinge can also be hinged to the bottom bracket assembly 3, which can ensure the multi-degree-of-freedom adjustment capability of the screen connector, so that the angle of the screen 2 can be flexibly adapted to the tailgate with different opening angles and viewing positions.

[0031] refer to Figure 1 and Figure 3In one embodiment, one end of the bracket fixing buckle 8 is movably disposed inside the through groove, and the other end of the bracket fixing buckle 8 extends out of the through groove. The sliding of the fixing push button assembly can push the extended end of the bracket fixing buckle 8 into the through groove, and achieve the abutment of the extended end, thereby locking the trunk latch. The bracket fixing buckle 8 is designed as a lever-type movable component, with one end movably disposed inside the through groove as a fulcrum, and the other end extending out as a clamping arm. When the user pushes the fixing push button assembly to slide, the inner wall of the push button assembly will act on the extended end of the bracket fixing buckle 8. The protruding end is forcibly pushed into the through groove, so that the two opposing bracket fixing buckles 8 protrude tightly abut against each other, thus firmly locking the trunk latch from both sides like jaws. This "outside-in" clamping method can generate greater locking force and higher structural rigidity compared to buckles that rely solely on elasticity, effectively preventing the trunk latch from shaking and coming off under lateral force. When disassembly is required, the clamping force can be released by sliding the push button in the opposite direction. The whole process does not require rough pulling, achieving non-destructive installation and protection of the trunk latch.

[0032] refer to Figure 1 and Figure 3 In one implementation, two telescopic rods 14 are provided, and each end of the two telescopic rods 14 connected to the hinge is provided with at least two hinge pieces. The at least two hinge pieces on the two telescopic rods 14 are staggered and hinged to the hinge. The staggered multiple hinge pieces form a wider force-bearing surface, which distributes the tension or wind torque from the curtain 2 more evenly to the hinge and the bracket fixing seat 11, effectively avoiding single-point stress concentration, greatly improving the shear and torsional strength of the hinge part, and enabling the bracket to support a larger and heavier curtain 2. The multiple hinge pieces restrict each other, strictly limiting the extra degrees of freedom of the telescopic rods 14 in the non-rotation direction, so that when the telescopic rods 14 are unfolded or the angle is adjusted, the hinge point has no play and the movement trajectory is stable and accurate, thereby ensuring the flatness of the hanging plane of the curtain 2.

[0033] It should be noted that the hinge has a through hole, and the hinge plate has a connecting hole that connects to the through hole. The hinge hole and the through hole are connected by the first screw 9 and the nut 12 to realize the hinge between the hinge and the telescopic rod 14.

[0034] refer to Figure 1 and Figure 3 As a preferred embodiment, the fixed push button assembly includes components disposed on the bracket mounting base 11. Shaped fixed push button 10, The fixed push button 10 is provided with a similar shape to The open end of the U-shaped fixed push button 10 is connected to the push button fixing plate 13, and the U-shaped groove is formed on the push button fixing plate 13 and is set on the bracket fixing base 11. The fixed push button 10 and the push button fixing plate 13 form a rigid linkage whole. The U-shaped groove opened on the push button fixing plate 13 directly serves as the interface for mating with the trunk latch, which can accommodate the trunk latch. While ensuring the structural strength of the entire fixed push button assembly (i.e. without omitting the push button fixing plate 13, the trunk latch can be locked), thus improving the overall reliability of the product.

[0035] It should be noted that the hinge and the bracket fixing seat 11 are set at an angle to limit the fixed push button assembly and prevent the fixed push button assembly from sliding out.

[0036] refer to Figure 1 and Figure 3 In one implementation, the telescopic rod 14 includes at least two sleeves that are sequentially nested together. The diameter of adjacent sleeves decreases sequentially, and a locking mechanism is provided between the nested adjacent sleeves. By adopting a multi-stage sleeve structure with decreasing diameter and a reliable locking mechanism, the core support component of the bracket can be adjusted and precisely locked within a wide range. That is, the multi-stage nesting of sleeves allows the length of a single telescopic rod 14 to be continuously adjusted between a compact storage size and a large extension size, thereby easily adapting to different width requirements from portable to large projection screens 2. The locking mechanism between each stage of sleeves ensures a firm mechanical lock at any adjustment position, effectively preventing accidental shrinkage or loosening caused by external force or vibration during use, and providing a rigid and wobbly suspension base for the screen 2.

[0037] It should be noted that the locking mechanism includes threaded structures at the ends of adjacent sleeves. The threaded structures are located on the inner and outer walls of the adjacent sleeves, and the adjacent sleeves are engaged by threads. This threaded locking mechanism achieves the most stable, reliable, and wobbly mechanical locking after the telescopic rod 14 is adjusted by directly setting the engaging ends of the adjacent sleeves as threaded structures that are screwed together. Specifically, the direct engagement of the inner and outer threads upgrades the connection between the sleeves from simple friction or snap-locking to a rigid connection of surface contact, so that the multi-stage sleeves are combined into a nearly integrated rigid rod in the extended state, completely eliminating the slight play or elastic deformation that may exist in traditional locks, thereby being able to withstand greater tension of the screen 2 and lateral wind force, and ensuring that the surface of the projection screen 2 is extremely flat.

[0038] The locking mechanism can also be grooves and protrusions set on the inner and outer walls of the ends of adjacent sleeves to achieve quick locking between adjacent sleeves.

[0039] refer to Figure 1 and Figure 2As one implementation, the system also includes a curtain height adjustment assembly 1 that simultaneously supports both sides of the curtain 2. Two curtain height adjustment assemblies 1 are provided, each including a support rod 7. An end fixing member 6 is fitted around the outer periphery of the support rod 7. The end fixing member 6 can slide along the axial direction of the support rod 7. Two end fixing members 6 are provided, one for fixing the bottom and one for fixing the top of the curtain 2. By providing two independent end fixing members 6 that can slide and adjust along the axial direction of the support rod 7, precise control of the vertical tension of the curtain 2 is achieved. Specifically, the top of the curtain 2... The bottom and top are respectively fixed to two independent sliding fasteners. Users can precisely control the overall hanging height and vertical flatness of the screen 2 by adjusting the position of these two fasteners. This effectively solves problems such as central sagging caused by the weight of the screen 2 itself or bottom tilting caused by uneven ground. It ensures that the screen 2 can present a perfect rectangular plane in any environment. Combined with the adjustable-spacing telescopic rod 14, it realizes independent or linked positioning of the four corners of the screen 2, so that a single bracket can intelligently adapt to various screens 2 with different aspect ratios and different suspension methods (such as with or without a bottom rod).

[0040] It should be noted that the mating end of the end fixing member 6 and the support rod 7 can be a flexible structure (i.e., made of rubber or silicone). The inner diameter of the flexible structure is smaller than the outer diameter of the support rod 7, so that the elasticity of the flexible structure can wrap around the outer wall of the support rod 7, thereby fixing the end fixing member 6 at any position on the support rod 7. The mating end of the end fixing member 6 and the support rod 7 can also be a connection relationship through the cooperation of groove and protrusion structure. That is, multiple protrusion structures are provided at intervals on the support rod 7, and the mating end of the end fixing member 6 and the support rod 7 is provided with a groove structure. Through the cooperation of the protrusion structure and the groove structure, the end fixing member 6 can be fixed at multiple positions on the support rod 7.

[0041] This invention also discloses a vehicle-mounted screen, including the vehicle-mounted screen support mentioned above, and a fixing cylinder for fixing the top and bottom of the screen 2. At least two fixing male buckles 4 are provided on the fixing cylinder at the top of the screen 2. The fixing male buckles 4 are connected to the screen connector. The at least two fixing male buckles 4 on the top fixing cylinder can achieve a quick and precise "click" connection with the corresponding interface (such as female buckle, slot or hook) of the screen connector on the bracket. This design completely eliminates the cumbersome straps, hanging ropes or Velcro operations in traditional suspension, and realizes the instant assembly and disassembly of the screen 2 and the bracket.

[0042] It should be noted that both ends of the fixing cylinder located at the top and bottom of the curtain 2 are provided with end connectors 5 that are connected to the end fixing parts 6, so as to realize the connection between the fixing cylinder and the end fixing parts 6.

[0043] refer to Figure 1 and Figure 2 As one implementation method, the fixing male buckle 4 can slide along the bottom of the fixing cylinder, allowing the fixing male buckle 4 to slide along the bottom of the fixing cylinder. That is, the connection point between the screen 2 and the bottom support assembly 3 is no longer fixed. This allows the user to fine-tune the precise position of each male buckle in the horizontal direction according to the actual support structure (such as the spacing of the telescopic rod 14) or the characteristics of the screen 2 itself (such as the non-standard spacing of the fixing ring), thereby achieving the best alignment and stress distribution between the screen 2 and the support. This solves the problem of misalignment of connection points caused by manufacturing tolerances or design differences between different screen 2 brands, ensuring that the screen 2 can be tensioned evenly and without twisting on the support frame, avoiding wrinkles or deformation caused by uneven local stress, thus providing a near-perfectly flat reference plane for the projected image.

[0044] refer to Figure 1 and Figure 2 In one implementation method, the curtain connector is a fixing female buckle 17 set at the end of the telescopic rod 14. Through the plugging and matching of the fixing male buckle 4 and the fixing female buckle 17, the vehicle-mounted curtain can be quickly installed, improving the installation efficiency.

[0045] It should be noted that the fixing nut 17 and the telescopic rod 14 are fixedly connected by the second screw 15, and an O-ring 16 is provided between the fixing nut 17 and the telescopic rod 14. The screw connection ensures that the fixing nut 17 and the telescopic rod 14 form a rigid and secure mechanical connection, which can reliably transmit the tension and wind load of the screen 2, and avoid micro-vibration of the screen 2 caused by shaking of the connection point, thereby ensuring the static stability of the projected image. At the same time, the O-ring 16 added between the mating surfaces can compensate for manufacturing tolerances, ensure uniform pressure when the screw is tightened, and prevent deformation caused by local stress concentration.

[0046] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
