[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A car audio microphone, such as Figures 1 to 5 As shown, it includes a bottom plate 100, a T-shaped turntable 120 extending into the bottom plate 100 is rotatably provided at the top of the bottom plate 100, a U-base 150 is fixed at the top of the T-shaped turntable 120, a constraint frame 160 is rotatably provided in the U-base 150, a microphone 170 is sleeved in the constraint frame 160, and piston cylinders 180 are longitudinally fixed on both sides of the T-shaped turntable 120 in the bottom plate 100.

[0026] A piston 181 is slidably disposed in the piston cylinder 180, a piston rod 182 extending to the outside of the end of the piston cylinder 180 is fixed at one end of the piston 181, a driving rod 183 extending to the front surface of the bottom plate 100 is rotatably disposed in the piston rod 182, an end of the piston cylinder 180 away from the driving rod 183 is connected to the air pipe 130, and a suction cup 140 is connected to the end of the air pipe 130;

[0027] A hidden groove 102 is provided at the top of the bottom plate 100, and a hidden plate 110 is slidably provided in the hidden groove 102. The front and rear outer walls of the hidden plate 110 are provided with a rubber strip 111 extending into the hidden groove 102. A restraining groove 103 is provided at the contact position between the inner wall of the hidden groove 102 and the rubber strip 111.

[0028] The device is placed on the center console in the car and pushed toward the side close to the front windshield until the suction cup 140 contacts the glass. Then, an external force is applied to the driving rod 183 to rotate along its own axis, and the piston rod 182 sleeved on the outer wall moves toward the side away from the glass, and the piston 181 at the end moves in the piston cylinder 180 accordingly, and the interior is in a negative pressure state. The air pipe 130 connects the piston cylinder 180 and the suction cup 140, so the suction cup 140 will be firmly attached to the surface of the windshield. Finally, the device is stably placed on the middle platform to cope with the displacement or falling caused by inertia when the vehicle starts and stops, and further improve the stability of the device;

[0029] After installation, the hidden panel 110 can be pulled to the left or right, and the rubber strips 111 on the front and rear sides prevent the hidden panel 110 from falling out of the hidden groove 102. At the same time, the friction between the two can be increased to cope with bumps. The ornaments in the car can be adhered to the upper surface of the hidden panel 110, and there is no need to clean the rubber strips on the center console later, which further enhances the convenience and flexibility of the device.

[0030] Please refer to Figure 1 A T-shaped disc groove 101 is provided at the contact position between the top of the bottom plate 100 and the T-shaped rotating disc 120 , and a rubber ring is embedded in the inner wall of the T-shaped disc groove 101 .

[0031] By using the T-shaped disc groove 101 and the T-shaped turntable 120, the microphone can be rotated according to personal needs so that it is at a required angle. At the same time, the rubber ring is used to increase the friction between the two to ensure that the rotated microphone will not rotate arbitrarily due to bumps.

[0032] Please refer to Figure 1 and Figure 4 A channel 104 extending to the front surface of the bottom plate 100 is opened at the contact position of the bottom plate 100 with the piston cylinder 180 , and the outer wall of the air pipe 130 is fixedly connected to the channel 104 .

[0033] The passage is used to provide a storage space for the piston cylinder 180, and external force can be applied thereto to make the piston cylinder 180 in a negative pressure state.

[0034] Please refer to Figure 5 The outer wall of one end of the piston rod 182 close to the driving rod 183 is fixedly sleeved with a limit strip 184 , and the left and right ends of the limit strip 184 extend into the channel 104 . A limit groove 105 is formed at the contact position between the inner wall of the channel 104 and the limit strip 184 .

[0035] The limiting groove 105 cooperates with the limiting strip 184 to ensure that the piston rod 182 moves linearly when the driving rod 183 rotates, and cooperates with the piston 181 at the end to finally achieve the purpose of negative pressure.

[0036] Please refer to Figure 1 The inner wall of the piston rod 182 is provided with an internal thread, and the outer wall of the driving rod 183 is provided with an external thread matching the internal thread.

[0037] When in use, external force is manually applied to the driving rod 183 to move the piston rod 182, thereby firmly fixing the microphone on the center console in the vehicle.

[0038] Please refer to Figure 1 The left and right outer walls of the constraint frame 160 are provided with a damping shaft extending into the U-seat 150 , and a base hole is opened at the contact position between the U-seat 150 and the damping shaft.

[0039] The damping shaft rotates in the base hole to change the angle of the microphone. At the same time, the damping shaft is used to increase the friction between the two to prevent the microphone from sagging due to its own weight.

[0040] When in use, the device is placed on the center console in the car and pushed toward the side close to the front windshield until the suction cup 140 contacts the glass. Then, an external force is applied to the driving rod 183 to rotate along its own axis, and the piston rod 182 sleeved on the outer wall moves toward the side away from the glass, and the piston 181 at the end moves in the piston cylinder 180 accordingly, and the interior is in a negative pressure state. The air pipe 130 connects the piston cylinder 180 and the suction cup 140, so the suction cup 140 will be firmly attached to the surface of the windshield. Finally, the device is stably placed on the middle platform to cope with the displacement or falling caused by inertia when the vehicle starts and stops, and the stability of the device is further improved.

[0041] After installation, the hidden plate 110 can be pulled to the left or right, and the rubber strips 111 on the front and rear sides prevent the hidden plate 110 from falling out of the hidden groove 102. At the same time, the friction between the two can be increased to cope with bumps. The ornaments in the car can be adhered to the upper surface of the hidden plate 110, and there is no need to clean the rubber strips on the center console later, which further improves the convenience and flexibility of the device. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
