Description

Technical Field

[0001] This utility model belongs to the field of all-in-one machine technology, and particularly relates to an in-vehicle all-in-one machine. Background Technology

[0002] The in-vehicle integrated unit combines PIS (Passenger Information System) broadcasting, media and video analysis, and is generally used in rail transit or buses.

[0003] After a period of use, dust accumulates on the display screen of a car infotainment system, affecting the display effect. Cleaning existing car infotainment systems is relatively troublesome. Since these systems are generally located on the roof of the vehicle, manual dust removal is quite difficult. Some car infotainment systems with cleaning mechanisms require additional power components and cleaning cloths, which increases costs. Moreover, the cleaning cloths also need to be removed and washed; otherwise, the cleaning effect will be affected after prolonged use.

[0004] Therefore, we propose an in-vehicle integrated unit to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of the cumbersome cleaning in the existing technology, and to propose an integrated vehicle-mounted machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle-mounted integrated machine includes a mounting frame, a display screen is rotatably mounted on the bottom surface of the mounting frame, cavities are provided inside both sides of the mounting frame, the rotation shaft of the display screen extends into the cavity and is fixedly fitted with a gear, and a rack of meshing gear is slidably provided on the side wall of the cavity.

[0008] A piston block that slides in the middle of the cavity and fits against the side wall of the cavity is provided. A drive assembly that drives the piston block to move is provided inside the cavity. A transmission assembly that drives the rack to move by moving the piston block is provided between the piston block and the rack.

[0009] The mounting bracket between the cavities on both sides has interconnected air passages inside, and the air passages are located on the side of the piston block facing the gear. The bottom surface of the air passages has multiple air holes facing the display screen.

[0010] Preferably, the transmission assembly includes a hydraulic cylinder fixedly mounted on the side wall of the cavity. The hydraulic cylinder has a first cylinder and a second cylinder that are interconnected inside. A first piston is slidably disposed in the first cylinder and is fixedly connected to a piston block by a first connecting rod. A second piston is slidably disposed in the second cylinder and is fixedly connected to a rack by a second connecting rod. The hydraulic cylinder between the first piston and the second piston is filled with hydraulic oil.

[0011] Preferably, the end of the first cylinder away from the second cylinder is fixedly connected to a first limiting ring that cooperates with the first piston, and the end of the second cylinder away from the first cylinder is fixedly connected to a second limiting ring that cooperates with the second piston.

[0012] Preferably, the cross-sectional area of ​​the first cylinder is smaller than that of the second cylinder.

[0013] Preferably, the cavity has horizontally formed grooves on both sides, and the rack extends into the grooves on both sides.

[0014] Preferably, the vent is inclined, and the lower end of the vent faces the display screen.

[0015] In summary, the technical effects and advantages of this utility model are as follows: This vehicle-mounted integrated unit achieves the transmission of the rack and pinion through a piston and transmission assembly. In conjunction with the gear, when the display screen is rotated downwards to turn on the machine, the piston moves to store air. When the display screen is rotated upwards to turn off the machine, the piston moves in the opposite direction to spray air from the air vent onto the display screen, thereby achieving automatic dust cleaning. Compared with existing devices, this avoids the problem of cumbersome dust cleaning steps and improves the practicality of the integrated unit. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 A vehicle-mounted integrated machine includes a mounting frame 1, a display screen 2 rotatably mounted on the bottom surface of the mounting frame 1, cavities 3 inside both sides of the mounting frame 1, the rotation shaft of the display screen 2 extends into the cavity 3 and is fixedly fitted with a gear 4, and a rack 5 meshing with the gear 4 is slidably mounted on the side wall of the cavity 3.

[0024] A piston block 6 is slidably mounted in the middle of the cavity 3, conforming to the side wall of the cavity 3. A drive assembly 7 is provided inside the cavity 3 to drive the piston block 6 to move. The drive assembly 7 is existing technology and can use an electric actuator solution, which is quite common and will not be described in detail here. A transmission assembly is provided between the piston block 6 and the rack 5, which drives the rack 5 to move by the movement of the piston block 6.

[0025] The mounting bracket 1 between the two cavities 3 has interconnected air passages 8 inside, and the air passages 8 are located on the side of the piston block 6 facing the gear 4. The bottom surface of the air passages 8 has multiple air holes 9 facing the display screen 2.

[0026] Reference Figure 1-3 When the display screen 2 needs to be rotated downwards to turn on the vehicle-mounted integrated machine, the piston block 6 is driven to move away from the hydraulic cylinder 10 by the drive component 7. At this time, the air enters the air passage 8 and the cavity 3 from the air hole 9 due to the influence of atmospheric pressure. At the same time, the rack 5 is driven to move towards the hydraulic cylinder 10 by the transmission component, and the gear 4 rotates accordingly, so the display screen 2 can be rotated downwards to turn on the machine.

[0027] When shutting down, the piston block 6 is driven to move closer to the hydraulic cylinder 10 by the drive component 7, and the rack 5 is driven to move away from the hydraulic cylinder 10 by the transmission component. The gear 4 rotates in the opposite direction, and the display screen 2 can rotate upward to shut down. At the same time, as the piston block 6 moves towards the hydraulic cylinder 10, the air is affected by the pressure and sprayed from the air hole 9 onto the display surface of the display screen 2, thereby cleaning the dust on the display screen 2.

[0028] Reference Figure 2-3 The transmission assembly includes a hydraulic cylinder 10 fixedly mounted on the side wall of cavity 3. Inside the hydraulic cylinder 10 are a first cylinder 11 and a second cylinder 12 that are interconnected. A first piston 13 slides within the first cylinder 11 and is fixedly connected to a piston block 6 by a first connecting rod 14. A second piston 15 slides within the second cylinder 12 and is fixedly connected to a rack 5 by a second connecting rod 16. The hydraulic cylinder 10 between the first piston 13 and the second piston 15 is filled with hydraulic oil 17. In this transmission assembly, the piston block 6 pushes the first piston 13 to move, and the hydraulic oil 17, in conjunction with this, moves the second piston 15. Furthermore, by setting a difference in the cross-sectional area between the first cylinder 11 and the second cylinder 12, a stroke difference between the first piston 13 and the second piston 15 can be achieved.

[0029] The first cylinder 11 is fixedly connected to a first limiting ring 18 that cooperates with the first piston 13 at one end away from the second cylinder 12, and the second cylinder 12 is fixedly connected to a second limiting ring 19 that cooperates with the second piston 15 at one end away from the first cylinder 11. The first limiting ring 18 and the second limiting ring 19 limit the first piston 13 and the second piston 15, thereby preventing the first piston 13 and the second piston 15 from disengaging from the hydraulic cylinder 10.

[0030] Since the rotation angle of the display screen 2 is generally less than 135° in actual use, the stroke of the rack 5 is relatively short. If the stroke of the rack 5 is the same as that of the piston block 6, less gas will be ejected from the air hole 9, affecting the cleaning effect. The cross-sectional area of ​​the first cylinder 11 is smaller than that of the second cylinder 12, so that the stroke of the first piston 13 is greater than that of the second piston 15.

[0031] The cavity 3 has horizontally opened grooves 20 on both sides, and the rack 5 extends into the grooves 20 on both sides. The grooves 20 limit and support the rack 5, thereby improving the stability of the rack 5 movement.

[0032] Reference Figure 4-5 The vent 9 is tilted, with the lower end of the vent 9 facing the display screen 2. This causes the airflow from the vent 9 to be directed at an angle onto the display screen 2, and the dust falls at an angle along the direction of the airflow, thus improving the dust cleaning effect.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
