no. 1 approach

[0036] Such as figure 2 As shown, the first threaded member 32 is provided with a positioning shaft 321, the second threaded member 33 is provided with a helical positioning hole 331 corresponding to the positioning shaft 321, and the driving device 31 drives the The first threaded member 32 rotates along the first direction, and the second restricting portion 12 restricts the rotation of the second threaded member 33 through the first restricting portion 341 , so that the first threaded member 32 and the second The screw joint 33 rotates relatively, the positioning shaft 321 moves along the helical positioning hole 331, the second screw joint 33 performs a telescopic movement, and pushes the terminal 20 out of the position through the locking member 34. The storage tank 11 is described. At this time, the positioning shaft 321 moves to the end position of the helical positioning hole 331, the second threaded member 33 cannot continue to rotate relative to the first threaded ...

no. 2 approach

[0038] Such as image 3 and Figure 4 As shown, in this embodiment, the first screw connection 32' is a screw, the second screw connection 33' is a screw sleeve, and the first screw connection 32' is connected to the second screw The pieces 33' are screwed together. When the driving device 31 drives the first threaded member 32 ′ to rotate in the first direction, because the second restricting portion 12 restricts the transmission member from rotating through the first restricting portion 341 , the second The threaded member 33 ′ performs telescopic movement relative to the first threaded member 32 ′, and the second threaded member 33 ′ pushes the terminal 20 out of the receiving groove 11 through the locking member 34 . The thread in the second threaded part 33' moves to the edge part of the thread of the first threaded part 32', and the first threaded part 32' and the second threaded part 33' cannot continue to rotate relative to each other. Moreover, at this moment, the ...

Abstract

The invention discloses a navigation device, which includes a housing, a terminal, a driving device, a first bolt connection member, a second bolt connection member, and a locking member, wherein thehousing is provided with a receiving slot for receiving the terminal; the locking member is used for locking the terminal; the first bolt connection member and the second bolt connection member are insleeving connection; the driving device drives the first bolt connection member to rotate; when the first bolt connection member and the second bolt connection member rotate relatively, the second bolt connection member performs telescopic movement relative to the first bolt connection member, the terminal is thus pushed out of the receiving slot by the locking member, the first bolt connection member and the second bolt connection member rotate to an extreme position at the time, the driving device can drive the first bolt connection member and the second bolt connection member to rotate together, the terminal is unlocked further through the locking member, by adopting the above movement, pushing the terminal out of the receiving slot and unlocking can be completed through one driving device and a transmission member, and the structure is simple.

Description

technical field [0001] The invention relates to the field of vehicle equipment, in particular to a navigation equipment. Background technique [0002] Along with the continuous upgrading of automobiles, navigation equipment is installed on most automobiles. Existing car navigation equipment is generally fixed on the dashboard of the car, and the display device of a part of the car navigation equipment can be disassembled. At present, the detachable car navigation equipment generally requires a relatively complicated transmission mechanism to complete the disassembly of the display terminal, and multiple driving devices are required to complete the disassembly work, the structure is relatively complicated, and the manufacturing cost is high. Contents of the invention [0003] In view of this, the present invention discloses a navigation device, which can complete the disassembly of the terminal through a relatively simple transmission method. [0004] The invention disclos...
