Description

Vehicle-mounted Bluetooth

Technical Field

The utility model relates to Bluetooth equipment, in particular to vehicle-mounted Bluetooth.

Background

The blue tooth technique in the vehicle blue tooth system is continued from the blue tooth technique of the mobile phone, and has the same transmitting system, the vehicle blue tooth is the wireless hand-free system in the vehicle which is designed and researched only based on the wireless blue tooth technique, the main function is to connect the blue tooth technique and the mobile phone to carry out hand-free communication in normal driving, and the purposes of liberating both hands and reducing hidden trouble of traffic accident are achieved.

However, after the vehicle-mounted bluetooth in the prior art is installed on a vehicle, the vehicle-mounted bluetooth is not easy to detach during maintenance.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide the vehicle-mounted Bluetooth, which can be quickly detached from a vehicle.

In order to solve the technical problems, the utility model adopts the technical scheme that:

the utility model provides an on-vehicle bluetooth, includes the casing and locates the bluetooth subassembly in the casing, still includes expansion bolts and transmission shaft, the big or small looks adaptation of the fixed orifices in the installation department on expansion bolts's the size and the car, expansion bolts locates on the lateral wall of casing, the rotatable locating of transmission shaft the casing, the transmission shaft both ends are run through the casing, just the one end of transmission shaft with the last screw rod of expansion bolts is connected.

Furthermore, the outer side wall of the expansion pipe of the expansion bolt is provided with an anti-skidding structure.

Furthermore, the outer side wall of the expansion pipe of the expansion bolt is provided with a convex part.

Furthermore, one end of the transmission shaft, which is far away from the expansion bolt, is provided with a knob which drives the transmission shaft to rotate.

Furthermore, expansion bolts are arranged on two sides of the shell and are symmetrically arranged.

The utility model has the beneficial effects that:

by adopting the technical scheme, when the vehicle-mounted Bluetooth is disassembled, the transmission shaft is rotated, and drives the screw rod of the expansion bolt to rotate, so that the expansion pipe on the expansion bolt is contracted, and the vehicle-mounted Bluetooth can be disassembled; during the installation, only need insert expansion bolts in the fixed orifices on the car, then rotate the transmission shaft, the transmission shaft drives expansion bolts's screw rod and rotates toward opposite direction, makes the expansion pipe inflation on the expansion bolts, contradicts up to the inner wall of the fixed orifices on expansion pipe and the car, can be fixed with vehicle-mounted bluetooth.

Detailed Description

In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 and 2, a vehicle bluetooth device comprises a housing 1, a bluetooth module disposed in the housing 1, an expansion bolt 2 and a transmission shaft 3, wherein the expansion bolt 2 is composed of a screw rod 4 and an expansion pipe 5, the expansion bolt 2 moves on the expansion pipe 5 through the screw rod 4 to drive the expansion pipe 5 to contract or expand, the size of the expansion bolt 2 is matched with the size of a fixing hole in an installation part for installing the vehicle bluetooth device on a vehicle, the expansion bolt 2 is disposed on the outer side wall of the housing 1, the transmission shaft 3 is rotatably disposed on the housing 1, two ends of the transmission shaft 3 penetrate through the housing 1, one end of the transmission shaft 3 is connected with the screw rod 4 on the expansion bolt 2, the housing 1 of the technical scheme is provided with two expansion bolts 2 and two transmission shafts 3, the two expansion bolts 2 are symmetrically disposed on two sides of the housing 1, the two expansion bolts 2 and the two transmission shafts 3 are disposed on the housing 1 to stably fix the vehicle bluetooth device, saving space inside and outside wall of the housing 1.

The use principle is as follows:

when the vehicle-mounted Bluetooth is disassembled, the transmission shaft 3 is rotated, the transmission shaft 3 drives the screw rod 4 of the expansion bolt 2 to rotate, and the expansion pipe 5 on the expansion bolt 2 is contracted, so that the vehicle-mounted Bluetooth can be disassembled; during the installation, only need insert expansion bolts 2 in the fixed orifices on the car, then rotate transmission shaft 3, transmission shaft 3 drives expansion bolts 2's screw rod 4 toward opposite direction and rotates, makes expansion pipe 5 inflation on the expansion bolts 2, contradicts up to expansion pipe 5 and the inner wall of fixed orifices on the car, can be fixed with bluetooth car.

Referring to fig. 2, the outer side wall of the expansion pipe 5 of the expansion bolt 2 according to the present embodiment is provided with an anti-slip structure 6.

Adopt this technical scheme, set up anti-skidding structure 6 through the lateral wall at expansion pipe 5, can improve the frictional force of the fixed orifices in the installation department on expansion pipe 5 and the car, make the fixed more firm of on-vehicle bluetooth.

Referring to fig. 2, the expansion bolt 2 according to the present embodiment has a projection 7 on the outer wall of the expansion pipe 5.

By adopting the technical scheme, the limiting groove matched with the convex part 7 can be formed in the mounting part on the vehicle, and the convex part 7 is embedded into the limiting groove to further play a role in fixing when the expansion pipe 5 expands.

Referring to fig. 2, a knob 8 for driving the transmission shaft 3 to rotate is arranged at one end of the transmission shaft 3 far away from the expansion bolt 2.

By adopting the technical scheme, the transmission shaft 3 can rotate conveniently.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
