However, when the navigation mounting rear cover 210 is fastened to the back surface of the navigation front screen 100, since the touch area and the digital display area of the navigation front screen 100 are located on a same line, that is, the digital display mounting through hole 202 and the touch mounting through hole 204 are located on the same line of the navigation mounting rear cover 210, that is, the positions of the digital display mounting through hole 202 and the touch mounting through hole 204 in the horizontal direction remain consistent, at this time, the navigation mounting rear cover 210 is prone to have a deviation between upper and lower positions, that is, in a direction perpendicular to the line where the digital display mounting through hole 202 and the touch mounting through hole 204 are located, the digital display mounting through hole 202 is prone to excessively squeeze with a single side of the digital display communication terminal, and the touch mounting through hole 204 is prone to excessively squeeze with a single side of the touch communication terminal, thereby affecting normal use of each terminal.
In order to avoid the single-side extrusion of the navigation installation rear cover 210 and each terminal during the installation process, referring to fig. 3, the navigation installation rear cover 210 includes a rear cover body 212 and a plurality of longitudinal positioning members 214, the rear cover body 212 is covered on the back surface of the navigation front screen 100, the navigation front screen 100 is provided with a plurality of longitudinal positioning grooves 102, each longitudinal positioning member 214 is inserted into one of the longitudinal positioning grooves 102, the longitudinal positioning member 214 includes a longitudinal extending plate 2142 and a positioning inner panel 2144, the longitudinal extending plate 2142 is respectively connected with the rear cover body 212 and the positioning inner panel 2144, the positioning inner panel 2144 is located on one side of the longitudinal extending plate 2142 close to the navigation front screen 100, the positioning inner panel 2144 is embedded in the longitudinal positioning groove 102, the positioning inner panel 2144 is abutted to the bottom of the longitudinal positioning groove 102, the positioning inner panel 2144 is further provided with a positioning bolt hole 203, and the positioning inner panel 214203 is used for inserting a positioning bolt 203 connecting the navigation front screen 100.
In this embodiment, the longitudinal positioning members 214 are located at the edge of the rear cover body 212, specifically, the longitudinal positioning members 214 are located at the upper and lower sides of the rear cover body 212, so that the longitudinal positioning members 214 are distributed perpendicular to the direction of the straight line where the digital display mounting through hole 202 and the touch mounting through hole 204 are located. The longitudinally extending plate 2142 of the longitudinal retainer 214 serves as a web between the locating inner panel 2144 and the rear cover body 212 to facilitate extending the locating inner panel 2144 beyond the edge of the rear cover body 212 so that the locating inner panel 2144 may be identified when installed. Moreover, the positioning inner panels 2144 are in one-to-one correspondence with the longitudinal positioning grooves 102, and the positioning inner panels 2144 are connected to one side of the longitudinally extending plate 2142 near the longitudinal positioning grooves 102 such that the positioning inner panels 2144 are disposed toward the opening of the longitudinal positioning grooves 102. The positioning inner panel 2144 and the longitudinally extending plate 2142 are stacked, so that the longitudinal positioning member 214 presents a step structure, and the positioning inner panel 2144 protrudes toward the longitudinal positioning groove 102, so that the positioning inner panel 2144 is embedded in a side edge of the front navigation screen 100. Because the longitudinal positioning grooves 102 correspond to the longitudinal positioning members 214, a plurality of longitudinal positioning grooves 102 form positioning distribution in the longitudinal direction, and accurate installation and positioning are conveniently provided in the longitudinal direction according to the alignment condition of the longitudinal positioning grooves 102 and the positioning inner panel 2144, so that the situation that the digital display installation through holes 202, the touch control installation through holes 204 and corresponding terminals are excessively extruded on one side during installation is avoided.
In another embodiment, the caliber of the notch of the longitudinal positioning groove 102 is larger than the diameter of the positioning inner panel 2144, so that the positioning inner panel 2144 can be adjusted in a laterally movable manner in the longitudinal positioning groove 102, thereby avoiding the situation that the digital display mounting through hole 202 and the touch mounting through hole 204 are excessively extruded from the other single side of the corresponding terminal during mounting.
