Embodiment Construction

[0022] The technical solutions of the present invention will be further explained below in conjunction with the drawings and embodiments, but the following content is not intended to limit the protection scope of the present invention.

[0023] This embodiment provides a translation and turning transmission device for a vehicle navigation system, the movement of the display screen of the navigation device is as follows: figure 1 as shown, figure 1 Middle: case 1, display screen 2, base 3, connecting rod 4, slider 5, crank 6, rack 7, chute 8. The transmission device must be able to drive the display screen to extend out of the chassis horizontally and turn over about 95 0 , while providing a stable and reliable support for the display.

[0024] Such as figure 2 As shown, the transmission is divided into two parts according to the function, figure 2 Middle: display screen 2, base 3, crank 6, rack 7, sliding pin 9, torsion spring 10, motor 11. The first part is the rack an...

Abstract

The invention discloses a translation and overturn drive device for a vehicle-mounted navigation system, which comprises a translation drive mechanism and an overturn mechanism, wherein the translation drive mechanism is a gear rack mechanism driven by a motor, is a drive source with constant ratio transmission, and is used for realizing the fore-and-aft translational motion of a base; and the overturn mechanism is a crank connecting rod mechanism, realizes the rotational motion of a crank by the driving power generated by the translation drive mechanism and the chute bind of the crank, and drives a display screen to roll over. Due to the method of the assembly driven by a set of single motor such as a gear rack mechanism, a connecting rod, a chute and the like, the device can translate and overturn the display screen. Due to the assembly method of the mechanism, the device realizes the single drive source and realizes the two-dimension drive. Compared with the two-dimension individual drive, a set of drive mechanism is omitted, and the assembled mechanism is good in mechanism rigidity and integrity, so that the movement range and the complexity of the mechanism can be reduced. Therefore, the device is small in occupancy space, simple in structure, low in cost, good in rigidity, and strong in practical applicability.

Description

technical field [0001] The invention relates to a device in the technical field of a vehicle navigation system, in particular to a translation and turning transmission device for a vehicle navigation system. Background technique [0002] Vehicle-mounted GPS navigation system, its built-in GPS antenna will receive the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the vehicle-mounted navigator, the position determined by the GPS satellite signal The coordinates are matched with this to determine the exact position of the car in the electronic map, which is the so-called positioning function. On the basis of positioning, the multi-function monitor can provide the best driving route, road conditions ahead, and the nearest gas station, restaurant, hotel and other information. If unfortunately the GPS signal is interrupted and you get lost because of this, don't worry, the GPS has recorded the driv...
