Description

Technical Field

[0001] This invention relates to the field of automotive flip-up display technology, specifically to an automotive flip-up display assembly. Background Technology

[0002] With the accelerated development of automotive intelligence, flip-up in-vehicle displays have become standard equipment in high-end models. These displays achieve dynamic adjustment of the screen angle through a precise adjustment mechanism, meeting the driver's information access needs while avoiding interference from strong glare. They can also be flipped and hidden when parked to protect the screen. However, within the current technological framework, these adjustment mechanisms generally suffer from a core defect: a lack of lubrication. This makes it difficult to overcome technological bottlenecks in terms of device durability and user experience, such as the lack of an effective, durable, and user-friendly built-in lubrication function.

[0003] After frequent friction, the initial small amount of grease in the sliding blocks, bearings, shafts, and other metal or high-strength engineering plastic components of the adjustment mechanism will gradually dry out, wear down, or become contaminated with dust. Lack of subsequent lubrication replenishment will lead to dry friction between components, resulting in noticeable squeaking, jerking noises, or motor whine when the screen is flipped. This not only severely compromises the quietness and luxurious experience expected of high-end vehicles but also makes users perceive a decline in product quality.

[0004] In view of this, a car flip-up display assembly is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automotive flip-up display assembly that possesses advantages such as self-lubrication, thus solving the problem of existing screen adjustment devices lacking effective and long-lasting lubrication.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automotive flip-up display assembly, comprising a base and a display body rotatably mounted on the base, wherein the base is provided with an adjustment mechanism for flipping the display body, and the base is provided with a piston structure for use with the adjustment mechanism.

[0007] The piston structure includes a cylinder fixedly disposed inside the base. The cylinder has a cavity, and a partition is fixed inside the cylinder. The cavity forms a first chamber and a second chamber through the partition. Both the first chamber and the second chamber are provided with pistons. A stop rod extending to the outside of the cylinder is fixed between the two pistons. The end of the stop rod is fixed with an abutment block that abuts against the adjustment mechanism. The base is also provided with a suction cup that cooperates with the piston structure.

[0008] Furthermore, the base has a storage slot, a sliding slot, and a mounting slot inside. The sliding slot and the mounting slot are both located on the side of the base, and the storage slot is used to store the display screen body.

[0009] Furthermore, the adjustment mechanism includes a drive structure disposed inside the base and a movable seat slidably disposed in the slide groove, wherein one side of the movable seat is hinged to the outer wall of the display screen body.

[0010] Furthermore, the drive structure includes a drive motor fixed inside the base, a lead screw fixed on the output shaft of the drive motor, and a connecting seat fixed to the bottom side of the movable seat connected to the external thread of the lead screw. The movable seat abuts against the abutting block through the adjustment of the drive structure, and the movable seat drives the display screen body to rotate using a connecting rod.

[0011] Furthermore, a connecting pipe is provided between the movable seat and the second chamber, and the connecting pipe consists of a rigid pipe and a corrugated telescopic pipe.

[0012] Furthermore, one end of the rigid tube is fixed to the movable seat, and the other end of the rigid tube is connected to the corrugated telescopic tube, and the other end of the corrugated telescopic tube is connected to the second chamber.

[0013] Furthermore, a valve pipe communicating with the first chamber and the second chamber is fixed on the outer wall of the cylinder. The valve pipe in the first chamber is fixed with a vacuum pipe communicating with the suction cup, and the valve pipe in the second chamber is fixedly connected to the end of the corrugated telescopic tube.

[0014] Furthermore, the cylinder is fixed inside the mounting groove, the stopper rod extends into the sliding groove, and a return spring is fixed to the outer surface of the stopper rod and one side of the outer wall of the cylinder.

[0015] Furthermore, the interior of the movable seat is hollow, and an infusion port is provided inside the movable seat.

[0016] Furthermore, the suction cups are detachably installed on the bottom wall of the storage groove, and there are at least two suction cups, with an air supply pipe installed between two adjacent suction cups.

[0017] Compared with the prior art, the present invention provides an automotive flip-up display assembly, which has the following beneficial effects:

[0018] 1. This car flip display assembly links the lubrication action with the screen flipping action. The screen is automatically lubricated every time it flips, ensuring the timeliness and regularity of lubrication. This completely solves the fundamental defect of lack of lubrication. At the same time, the amount of lubricating oil supplied is directly related to the frequency and stroke of screen flipping. The more frequently it is used, the more times it is lubricated, avoiding the waste of lubricating oil or pollution caused by excessive use.

[0019] 2. In this automotive flip-up display assembly, lubricating oil is delivered directly and precisely to the critical parts that require lubrication, such as the friction surfaces of the sliding grooves of the moving seat, through a hollow movable seat and carefully designed inlet holes. This effectively reduces wear, eliminates abnormal operating noise, and greatly extends the service life of the drive structure.

[0020] 3. This automotive flip-up display assembly features a dual-function design: when the piston rod is pushed, one chamber pumps oil for lubrication, while the other chamber creates a vacuum for suction and fixation. This achieves synchronized operation and synergistic effects. While the screen flips out, the lubrication system protects the adjustment mechanism. When the screen is retracted, the suction system immediately and firmly secures it, resisting vehicle vibrations. This effectively addresses the issue of traditional mechanical clips loosening and generating noise under prolonged vibration. The vacuum suction cup fixation provides a flexible, powerful, and noiseless fixation solution, significantly improving the stability of the screen in its retracted state and the overall NVH performance of the vehicle.

[0027] 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.

[0028] Please see Figures 1 to 5 A car-mounted flip-up display assembly includes a base 1 and a display body 2 rotatably mounted on the base 1. The base 1 contains an adjustment mechanism for flipping the display body 2, and a piston structure 5 that works in conjunction with the adjustment mechanism. Specifically, the base 1 has a storage slot 11, a sliding groove 12, and a mounting groove 13 inside, wherein the sliding groove 12 and the mounting groove 13 are both located on the side of the base 1. The storage slot 11 is used to store the display body 2. The base 1 can be bolted to the interior of the car. The storage slot 11 allows the display body 2 to be stored, preventing exposure and damage.

[0029] To achieve the flipping of the display screen body 2, the adjustment mechanism includes a drive structure 3 disposed inside the base 1 and a movable seat 4 slidably disposed in the slide groove 12. A connecting rod 41 is hinged between one side of the movable seat 4 and the outer wall of the display screen body 2. Specifically, the drive structure 3 includes a drive motor 31 fixed inside the base 1. A lead screw 32 is fixed on the output shaft of the drive motor 31. The lead screw 32 is externally threaded to a connecting seat 33 fixed to the bottom side of the movable seat 4. The movable seat 4 abuts against the abutment block 57 through the adjustment of the drive structure 3, and the movable seat 4 uses the connecting rod 41 to drive the display screen body 2 to flip. The movable seat 4 and the display screen body 2 are hinged through the connecting rod 41 to form a stable triangular mechanical structure, ensuring that there is no shaking or jamming during the flipping process, improving the smoothness of operation and service life.

[0030] To achieve timely lubrication, the piston structure 5 includes a cylinder 51 fixedly disposed inside the base 1. The cylinder 51 has a cavity, and a partition 52 is fixed inside the cylinder 51. The cavity forms a first chamber 53 and a second chamber 54 through the partition 52. Pistons 55 are disposed inside both the first chamber 53 and the second chamber 54. A stopper rod 56 extending to the outside of the cylinder 51 is fixed between the two pistons 55. An abutment block 57 that abuts and cooperates with the adjustment mechanism is fixed at the end of the stopper rod 56. A suction cup 6 that cooperates with the piston structure 5 is also disposed inside the base 1.

[0031] Specifically, a connecting pipe 7 is provided between the movable seat 4 and the second chamber 54. The connecting pipe 7 consists of a rigid pipe 71 and a corrugated expansion pipe 72. One end of the rigid pipe 71 is fixed to the movable seat 4, and the other end of the rigid pipe 71 is connected to the corrugated expansion pipe 72. The other end of the corrugated expansion pipe 72 is connected to the second chamber 54.

[0032] A valve pipe 59, which communicates with the first chamber 53 and the second chamber 54, is fixed on the outer wall of the cylinder 51.

[0033] In this configuration, the valve tube 59 on the first chamber 53 is fixed with a vacuum tube communicating with the suction cup 6, and the valve tube 59 on the second chamber 54 is fixedly connected to the end of the corrugated telescopic tube 72. The cylinder 51 is fixed inside the mounting groove 13, the stopper rod 56 extends into the sliding groove 12, and a return spring 58 is fixed to the outer surface of the stopper rod 56 and one side of the outer wall of the cylinder 51.

[0034] It should be noted that the interior of the movable seat 4 is hollow, and an infusion hole 42 is provided inside the movable seat 4. The suction cup 6 is detachably installed on the bottom wall of the storage groove 11. There are at least two suction cups 6, and an air supply pipe 61 is installed between two adjacent suction cups 6. The vacuum tube of the suction cup 6 is connected through the valve pipe 59 to form a negative pressure adsorption system. When the stop rod 56 is pushed by the movable seat 4, the piston 55 compresses the first chamber 53, sucking the air in the suction cup 6, realizing strong fixation of the display screen body 2 when stored, effectively resisting vehicle bumps and vibrations, and solving the problem of easy loosening of traditional mechanical locks;

[0035] In addition, by connecting the valve pipe 59 to the connecting pipe 7, and with the installation of the corrugated telescopic pipe 72 and the return spring 58, fluid buffering is achieved. When the moving seat 4 moves, the second chamber 54 expands to draw in fluid, which not only buffers mechanical impact, but also achieves self-lubrication through fluid flow, reducing frictional wear between the connecting rod 41 and the lead screw 32, and extending the life of precision components.

[0036] The working principle of the above embodiments is as follows:

[0037] First, when the drive motor 31 starts, it drives the lead screw 32 to rotate. The connecting seat 33, which meshes with the lead screw 32, drives the moving seat 4 to slide forward toward the piston structure 5 in the slide groove 12. During the sliding process, the side of the moving seat 4 will contact the abutment block 57 and continuously press it. After the abutment block 57 is pressed, it pushes the piston rod 56 to move into the cylinder 51. The piston rod 56 drives the two pistons 55 to move inward, compressing the volume of the second chamber 54.

[0038] The second chamber 54 is compressed, and the lubricating oil inside is precisely pumped into the hollow movable seat 4 through the valve pipe 59 and the connecting pipe 7 under pressure. After entering the movable seat 4, the lubricating oil flows out through the infusion hole 42 opened inside it. The flowing lubricating oil drips directly onto or is applied to the wall surface of the movable seat 4 that is in operation, so as to achieve instant lubrication of the transmission mechanism and sliding pair.

[0039] At the same time, the volume of the first chamber 53 is expanded, and a negative pressure is formed inside. This negative pressure is transmitted to the suction cup 6 installed at the bottom of the storage slot 11 through the valve pipe 59 on the first chamber 53 and the vacuum pipe connected to it. The suction cup 6 generates suction force, which can adsorb the display screen body 2 and fix the display screen body 2.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
