Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted navigation screens, and specifically provides a vehicle-mounted navigation screen and a vehicle. Background Art

[0002] The in-car navigation screen is a display screen installed in the center console of the car. It is mainly used to display maps, multimedia, reversing images, and connect to Bluetooth. For example, the in-car navigation screen has a built-in high-precision GPS module, which can display the vehicle's location in real time and provide a variety of route planning options to help drivers reach their destination quickly and accurately; the in-car navigation screen usually supports a variety of audio and video formats, and the driver can connect the mobile phone to the device through the USB interface or Bluetooth to play music, videos and other multimedia content; the in-car navigation screen also integrates the reversing image function, which displays the image behind the vehicle in real time by connecting to the camera at the rear of the car, helping the driver to more accurately judge the distance and the location of obstacles when reversing.

[0003] Existing vehicle navigation screens are generally embedded in the center console of the car. Some vehicle navigation screens also have a circular trajectory lifting function for the convenience of operation and viewing. A circular trajectory with a height difference is formed by a rotating mechanism or a connecting rod mechanism, so that when the vehicle navigation screen moves along the circular trajectory, the vehicle navigation screen can also move up and down at the same time. The vehicle navigation screen is lifted and lowered by controlling the circular trajectory, and there are only two modes: lifting the display box and retracting and hiding the display box. The size of existing vehicle navigation screens is gradually increasing, and more rotation space is required when lifting and lowering, and the gear mode is single. At the same time, the structure for controlling the lifting of the vehicle navigation screen by a circular trajectory occupies a large space in the horizontal direction.

[0032] Example 1

[0033] This embodiment provides a specific implementation of the vehicle navigation screen. Figure 1 , Figure 2 and Figure 3 As shown, it includes a screen 2, a power device 4, a power transmission device, a lifting mechanism 6, and a shell 3, wherein the shell 3 is installed at the center console of the car, the screen 2 can be slid up and down on the side of the shell 3, the power device 4, the power transmission mechanism 5 and the lifting mechanism 6 are all arranged in the shell 3, the screen 2 is connected to the driving end of the lifting mechanism 6, and the lifting mechanism 6 is connected to the power device 4 through the power transmission mechanism 5. The power device 4 can drive the lifting mechanism 6 through the power transmission device to drive the screen 2 to move up and down in the vertical direction. The vehicle-mounted navigation screen provided in this application only moves up and down in the vertical direction. By controlling the lifting mechanism 6, the screen 2 can be fully displayed, partially displayed or completely hidden to adapt to a larger screen. When fully displayed, it is a large screen, which can bring a better visual experience; when partially displayed, the height of the screen 2 can be adjusted according to the driver's line of sight to avoid the screen 2 affecting the driver's line of sight; when completely hidden, the screen can be completely hidden at the center console. At the same time, the vehicle navigation screen only needs to be moved up and down by the lifting mechanism 6. The distance between the vehicle center console and the chassis can meet the lifting space of the vehicle navigation screen, avoiding lifting through a circular trajectory, saving horizontal installation space in the vehicle, and facilitating the installation of other components.

[0034] In this embodiment, the lifting mechanism 6 includes a driving gear 61 and a rack 62 meshing with the driving gear 61. The screen 2 is connected to the rack 62. The rack 62 moves up and down under the rotation drive of the driving gear 61 to drive the screen 2 to move up and down. The screen 2 is driven up and down by the cooperation of the driving gear 61 and the rack 62, so that the screen 2 can be fully displayed, partially displayed, and completely hidden. When partially displayed, the height of the displayed part of the screen 2 can be controlled according to the height of the rack 62. The rack and pinion transmission has high transmission accuracy and can realize the precise up and down movement of the screen 2. The high accuracy comes from the good meshing between the driving gear 61 and the rack 62, and can maintain high positioning accuracy even under long-term use or high load conditions. Due to the structural characteristics of the rack and pinion, it has high stability during the transmission process and is not prone to shaking or offset, thereby ensuring the smooth movement of the screen 2. The rack and pinion transmission also has a large load-bearing capacity and can cope with the weight of the screen 2 and its additional components, making the rack and pinion very suitable for screens 2 that need to be frequently moved up and down and are heavy. At the same time, the rack and pinion transmission also has high load adaptability and can maintain stable transmission performance under different load conditions. The rack and pinion transmission mechanism After optimized design, higher transmission efficiency can be achieved. When driving the screen 2 to move up and down, energy can be used more effectively and energy consumption can be reduced. In addition, the rack and pinion transmission mechanism generates relatively low noise during operation, which is crucial to improving user experience and maintaining a quiet and comfortable environment in the car; the rack and pinion transmission mechanism has a simple structure and a high degree of component standardization, which is convenient for maintenance and replacement of parts; the rack and pinion transmission mechanism has been precisely processed and rigorously tested, with high reliability and durability, and can operate stably for a long time in harsh environments, providing reliable power support for the up and down movement of the navigation screen; due to its high transmission efficiency and low energy consumption, as well as relatively low maintenance cost, the rack and pinion transmission mechanism can save users a certain amount of cost in long-term use.

[0035] In this embodiment, the lifting mechanism 6 adopts a gear rack transmission mechanism, which has the advantages of high precision and stability, large load capacity and high load adaptability, high transmission efficiency and low noise, convenient maintenance and low cost, first-level reliability and long life.

[0036] In some other embodiments, the lifting mechanism 6 can also be a screw lifting mechanism, an electric push rod lifting mechanism, a chain drive lifting mechanism, a gas spring lifting mechanism, a scissors-type lifting mechanism, etc., as long as it can drive the screen 2 to move up and down.

[0037] In this embodiment, the power transmission mechanism 5 includes a gear set 51, which is connected to the driving gear 61 through the transmission shaft 12. The power device is a driving motor 41, and the driving shaft of the driving motor 41 is connected to the gear shaft. The driving motor 41 transmits power to the gear set 51 through the driving shaft, and the gear set 51 then transmits power to the transmission shaft 12. The transmission shaft 12 drives the driving gear 61 to rotate, so as to drive the rack 62 and the screen 2 to move up and down. The use of the gear set 51 for power transmission has higher transmission accuracy, and the speed transmitted by the driving motor 41 can also be adjusted as needed to adapt to the lifting speed of the screen 2. The use of gear set 51 for power transmission can maintain a constant transmission ratio, so that the ratio of output speed to input speed remains unchanged, ensuring the accuracy and reliability of transmission; the efficiency of gear transmission is usually high, which can reach more than 95%, and can effectively reduce the loss of energy in the transmission process; gear transmission is suitable for a wide range of power and speed, and can meet the needs of different application scenarios; the structural design of gear transmission is compact, and can achieve efficient transmission in a limited space, which is suitable for occasions with limited space; gear transmission has good stability, can reduce vibration and impact, and has a positive effect on the operating stability of the equipment; the gear transmission is reasonably designed and well manufactured, usually has a long service life, and can reduce maintenance costs; by changing the number of teeth on the gear or using gears of different sizes, the speed change of the mechanical system can be easily achieved to meet different transmission needs.

[0038] In some other embodiments, the power transmission mechanism 5 can also be implemented by a chain drive, a belt drive, a hydraulic drive, a pneumatic drive, an electromagnetic drive, etc., as long as the power device 4 can drive the lifting mechanism 6 to move. Chain drive transmits power through the meshing of a chain and a sprocket. The chain is usually composed of a plurality of links, each of which is equipped with a roller or a sleeve to reduce friction and wear. The sprocket has a tooth shape that matches the chain so that the chain can roll smoothly on the sprocket to drive the lifting mechanism 6 to drive the screen 2 to move up and down; belt drive uses the friction between the transmission belt (such as a flat belt, a V-belt, a synchronous belt, etc.) and the pulley to transmit power. The transmission belt is usually wound around two or more pulleys to form a closed or open transmission system, which drives the lifting mechanism 6 to drive the screen 2 to move up and down; hydraulic transmission uses the pressure energy of the liquid to transmit power. The hydraulic transmission system is usually composed of components such as a hydraulic pump, a hydraulic cylinder (or a hydraulic motor), a hydraulic valve, and a hydraulic pipeline. The hydraulic pump converts mechanical energy into liquid pressure energy, transmits it to the hydraulic cylinder or hydraulic motor through the hydraulic pipeline, and then converts it into mechanical energy output to drive the lifting mechanism 6 to drive the screen 2 to move up and down; the electromagnetic transmission uses electromagnetic force to transmit power. The electromagnetic transmission system usually includes components such as electromagnets, armatures and springs. When the electromagnet is energized, an electromagnetic force is generated to attract the armature to move; when the power is off, the armature is reset under the action of the spring, driving the lifting mechanism 6 to drive the screen 2 to move up and down. Both chain transmission and belt transmission can drive the driving gear 61 to rotate, and then drive the rack 62 to move up and down; hydraulic transmission, electric transmission and electromagnetic transmission can match other lifting mechanisms 6, such as screw lifting mechanisms, electric push rod lifting mechanisms, etc.

[0039] In this embodiment, a damping device is also included, which is arranged between the transmission shaft 12 and the driving gear 61. The damping device includes a disc damper 9 and a disc damper shaft 8. The disc damper shaft 8 is connected to the gear shaft. The end of the disc damper shaft 8 is provided with a damping disc 81 that matches the disc damper 9. The damping disc 81 cooperates with the disc damper 9 to further ensure the stability of the driving gear 61 and the rack 62 after the screen 2 stops moving, and keep the position of the screen 2 unchanged. The cooperation between the damping disc 81 and the disc damper 9 can effectively absorb and dissipate the vibration and impact energy generated during the transmission process. When the transmission shaft 12 is running at high speed or subjected to external impact, the damping system can slow down the transmission of vibration and impact through its damping characteristics, and protect the stability and reliability of the transmission system; the design of the damping disc 81 can make the transmission process more stable. By adjusting the parameters such as the material, shape and size of the damping disc 81, the size and characteristics of the damping force can be controlled, thereby achieving precise control of the transmission process. This helps to reduce noise and vibration during the transmission process and improve the overall operation quality of the equipment; the matching design of the damping disc 81 and the disc damping 9 can be adjusted and optimized according to different transmission requirements. For example, the damping characteristics of the damping disc 81 can be changed by changing the material; the size of the damping force can be changed by adjusting the gap between the damping disc 81 and the disc damping 9. This design makes the transmission system more adaptable and flexible; at the same time, it can also provide a certain damping force to the transmission shaft 12 to ensure the rotation accuracy of the transmission shaft 12.

[0040] In this embodiment, a damping sleeve 7 is also included, which is arranged between the gear shaft and the transmission shaft 12. A certain damping is designed between the damping sleeve 7 and the gear shaft. When the product is working normally, there will be no impact. When it is maliciously damaged, the damping sleeve 7 starts to take effect to prevent the product from being damaged and protect the drive motor 41 and the drive gear 61.

[0041] In this embodiment, an angle sensor 11 is further included, which is arranged on the transmission shaft 12. The angle sensor 11 is used to detect the rotation angle of the transmission shaft 12 to ensure the accuracy of the up and down movement of the rack 62, and further ensure the accuracy of the up and down movement of the screen 2.

[0042] In this embodiment, a guide assembly 10 is further included. The guide assembly 10 is arranged between the screen 2 and the housing 3. The guide assembly 10 can guide the screen 2 to move up and down. When the screen 2 is driven by the rack and pinion transmission mechanism to move up and down, it is guided by the guide assembly 10 to improve the stability and accuracy of the screen 2 when it moves up and down.

[0043] Furthermore, the guide assembly 10 includes a slide rail 101 installed on the side of the shell 3 and a slider 102 slidably installed on the slide rail 101. The screen 2 is connected to the slider 102. The slider 102 slides on the slide rail 101 to guide the lifting and lowering movement of the screen 2, thereby providing a stable movement path for the movement of the screen 2, ensuring the accuracy and stability of the screen 2 during the movement. The design of the slider 102 and the slide rail 101 reduces the shaking or deviation caused by the movement, thereby improving the stability and reliability of the overall system; at the same time, it can also reduce friction and wear, enhance the carrying capacity, and facilitate maintenance and replacement.

[0044] In some other embodiments, the guide assembly 10 may also be a gas spring guide structure, a flexible hinge guide structure, an electromagnetic guide structure, etc. The gas spring guide structure realizes guidance and support through the compressibility of gas; the flexible hinge guide structure realizes guidance and support of the screen 2 through the elastic deformation of the flexible hinge; the electromagnetic guide structure realizes guidance and movement of the screen 2 through electromagnetic force.

[0045] Furthermore, two groups of guide components 10 are provided, which are respectively located at two sides of the screen 2, so as to provide more stable support and guidance.

[0046] In this embodiment, the housing 3 and a number of components are mounted on a base 1, which is mounted to the center console of the vehicle through the base 1. A connecting plate 13 is provided between the screen 2 and the rack 62, and the screen 2 is connected to the rack 62 through the connecting plate 13, wherein the connecting plate 13 may include a plate-like structure and a circuit board, etc., as long as the connection between the screen 2 and the rack 62 can be achieved.
