Description

Technical Field

[0001] The invention relates to the field of automotive electronic equipment, and in particular to an external vehicle microphone and an external vehicle microphone mounting seat. Background Art

[0002] Exterior microphones, also called external microphones or on-board external microphones, are usually mounted on the outside of a vehicle and are used to capture sounds outside the vehicle.

[0003] For example, Chinese patent CN115379328A discloses an external microphone and an external microphone mounting base, which aims to solve the problem of damage to the housing and waterproof vibration membrane of the external microphone of a motor vehicle due to vibration in the prior art. The patent realizes that the external microphone housing and the vibration membrane are not easy to be damaged by the integrated setting, and the mounting base reduces the influence of the vibration of the motor vehicle on the microphone according to the use environment outside the vehicle.

[0004] However, although the above patents have improved the anti-vibration performance of the microphone to a certain extent, they still have the following shortcomings: The vibration reduction design of the above patent mainly focuses on the integrated setting of the microphone box and the vibration membrane, and does not take into account the vibration reduction ability of the mounting base itself. Under high-speed driving and complex road conditions, a single vibration reduction measure is difficult to effectively absorb vibrations from different directions, resulting in the microphone still being affected by vibrations, reducing its stability and service life. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention aims to provide an external vehicle microphone and an external vehicle microphone mounting base with a stable structure and higher reliability.

An extension opening is opened on one side of the lower part of the base, and the lower part of the top plate protrudes from the upper inner part of the base.

[0009] More preferably, when the top plate is pushed upward from the extension port of the base, the contact block thereon contacts the V-shaped notch, and the wedge block slides inward at the same time due to the pulling force generated during the contact, and the wedge block no longer presses against the matching groove of the microphone body, allowing the microphone body to be disassembled and assembled according to the threaded groove on the protective shell.

[0010] More preferably, the vibration-damping part of the external microphone mounting base includes sleeves respectively arranged at the extension end of the base plate and the bottom of the base, vibration-damping columns slidably arranged inside the sleeve, the opposite surfaces of each vibration-damping column in the first vibration-damping part are connected to the outside of the base, the upper end surface of each vibration-damping column in the other vibration-damping part is connected to the bottom of the top plate, springs are symmetrically arranged in the vibration-damping columns in each direction and the corresponding sleeves, washers suitable for the corresponding inner walls of the sleeves are arranged at the ends of the vibration-damping columns in each direction, and the washers in each direction are located between the symmetrical springs.

[0011] More preferably, the external microphone mounting base also includes a sealing cover, a limit lock, a torsion spring, a folding piece, a positioning block, a guide seat and a lifting frame. A sealing cover is hinged on the extension port on one side of the lower part of the base, and a limit lock is arranged above the lower part of the base corresponding to the sealing cover.

[0018] 3. The external microphone mounting base of the present invention changes the adsorption force of the suction cup by designing a release sleeve and an adjustment rod between the suction cup and the inside of the base plate, making it convenient for users to adjust the fixing strength of the base plate according to actual conditions.

[0034] Embodiment: This embodiment discloses an external vehicle microphone.

[0035] like Figure 1-Figure 3 and Figure 6-Figure 8 As shown, in this embodiment, the external microphone includes: The protective shell 4 is a concave hollow shell with an inner wall and an outer wall, which protects the microphone body 5 from the influence of the external environment and provides a structure for facilitating the installation and removal of the microphone body 5. A threaded groove is provided on the inner annular surface of the outer wall of the protective shell 4. A mounting frame 41 is fixed to the inner top of the inner wall of the protective shell 4 by screws. Wedge blocks 42 with wedge ends facing outward are slidably provided on both sides of the mounting frame 41. A V-shaped notch is provided on the inner lower part of the wedge blocks 42. Each wedge block 42 slides through the inner wall of the protective shell 4. A spring 43 is provided between the end of each wedge block 42 and the inner wall of the mounting frame 41. A top plate 44 is slidably provided in the lower inner part of the protective shell 4. The lower part of the top plate 44 protrudes from the inner upper part of its support. The lower end of the top plate 44 is connected to one of the components in another vibration reduction functional part. Two contact blocks 45 corresponding to the V-shaped notch are provided on the top of the top plate 44. The microphone body 5 is used as a main working part to capture the sound outside the vehicle. The microphone body 5 is threadedly arranged on the upper inner part of the protective shell 4 and is fixed by the threaded groove of the protective shell 4. Rectangular matching grooves are provided on both sides of the lower part of the microphone body 5, and the through-portion of the wedge block 42 forms an abutment state with the matching groove; when the top plate 44 is pushed upward from the extension port of the base 3, the contact block 45 thereon contacts with the V-shaped notch, and the wedge block 42 slides inward at the same time due to the pulling force generated during the contact, and the wedge block 42 no longer contacts the matching groove of the microphone body 5, thereby releasing the lock, so that the microphone body 5 can be quickly disassembled and assembled according to the threaded groove on the protective shell 4.

[0036] like Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the external microphone also includes a spring four 46. A spring four 46 for providing a reset force is arranged between the upper end surface of the top plate 44 and the inside of the protective shell 4. The spring four 46 ensures that the top plate 44 can return to its initial position after the disassembly operation is completed.

[0037] This embodiment also discloses an external vehicle microphone mounting base, which is mounted on the surface of the vehicle body and is used to mount the above-mentioned external vehicle microphone. Figure 1-Figure 5 and Figure 9-10 As shown, the exterior microphone mount includes: The base plate 1, as the foundation of the whole device, provides a bearing platform, and its edge is provided with four extension ends equidistantly for mounting the shock absorbing functional parts; The adhesive sheet 11 is attached to the center of the bottom of the base plate 1 and fixed to the surface of the vehicle body by adhesive, so as to install the whole device; The vibration reduction part 2 is a vibration reduction function part, which can reduce the influence of the vibration of the vehicle when it is running on the microphone body 5. It is divided into two locations. The first vibration reduction part 2 is relatively dispersedly arranged on the four extending ends of the substrate 1. The other vibration reduction part 2 is symmetrically arranged in the component carried by the first vibration reduction part 2, that is, the bottom of the base 3, and the lower end of the top plate 44 is connected to the component in the other vibration reduction part 2; The base 3 is a support member for fixing the protective shell 4, and is arranged between the opposite surfaces of the first vibration-damping part 2, and the protective shell 4 is embedded in the upper inner part of the base 3, and the other vibration-damping part 2 is arranged in a left-right symmetrical manner at the bottom of the base 3. A rectangular extension opening is opened on the front side of the lower part of the base 3 for disassembly and maintenance operations, and the lower part of the top plate 44 protrudes from the upper inner part of the base 3.

[0038] like Figure 1-Figure 5 and Fig. 9 As shown, in this embodiment, the vibration reduction part 2 of the external microphone mounting seat includes a sleeve 201 respectively set on the extension end of the substrate 1 and the bottom of the base 3 by welding, a vibration reduction column 21 slidably arranged inside the sleeve 201, the opposite surface of each vibration reduction column 21 in the first vibration reduction part 2 is connected to the lower position of the outside of the base 3, and the upper end surface of each vibration reduction column 21 in the second vibration reduction part 2 is connected to the bottom of the top plate 44, and the vibration reduction columns 21 in each direction and the corresponding sleeve 201 are symmetrically provided with springs 22, and the ends of the vibration reduction columns 21 in each direction are fixed with washers 23 suitable for the inner wall of the corresponding sleeve 201 by glue, and the washers 23 in each direction are located between the symmetrical springs 22; the spring 22 provides a reset force, and the washers 23 ensure good contact between the vibration reduction columns 21 and the inner wall of the sleeve 201.

[0039] like Figure 1-Figure 3 , Figure 5 and Fig. 9As shown, in this embodiment, the vehicle exterior microphone mounting base further includes a sealing cover 301, a limit lock 31, a torsion spring 32, a folding piece 33, a positioning block 34, a guide seat 35 and a lifting frame 36. A sealing cover 301 is hinged on the extension port on the front side of the lower part of the base 3. The sealing cover 301 closes the extension port of the base 3. By changing the adjustment mode, dust and moisture can be prevented from entering on the basis of adjustment, thereby ensuring the cleanliness and dryness of the internal components. A limit lock 31 is arranged above the lower part of the base 3 corresponding to the sealing cover 301. The lock core of the limit lock 31 abuts against the upper end of the sealing cover 301 to ensure that it remains in a closed state during normal operation. Torsion springs 32 are arranged at the hinges between the left and right ends of the sealing cover 301 and the base 3. The torsion spring 32 provides rotational power when the sealing cover 301 is opened, so that the sealing cover 301 is automatically opened. A folding piece 33 is hinged on the end surface of the sealing cover 301 close to the base 3. When the sealing cover 301 is opened, the folding piece 33 drives the positioning block 34 to slide by retracting and rotating. Then, the lifting frame 36 lifts up the top plate 44. Positioning blocks 34 are provided on both ends of the left and right ends of the folding part in the middle of the folding member 33. The lower end of the positioning block 34 is slidably connected to the bottom of the base 3. A guide seat 35 is provided at the middle and rear part of the bottom of the base 3. The insides of the two positioning blocks 34 are slidably connected to the guide rods of the guide seat 35 to ensure that the folding and rotating action of the folding member 33 is carried out smoothly. A lifting frame 36 is slidably provided at the rear of the guide seat 35 to lift up the top plate 44 and help disassembly of the microphone body 5. The end of the lifting frame 36 is hinged to the rear of the folding member 33, and is gradually raised by the sliding of the positioning block 34; after the limit lock 31 is opened, its lock core no longer presses against the sealing cover 301, and the torsion spring 32 is changed from a tightened state to a loose state, and drives the sealing cover 301 to rotate, and at the same time drives the folding member 33 to fold and rotate, gradually causing the positioning block 34 to slide continuously close to the end of the guide seat 35, and the folded and rotating folding member 33 is gradually raised, allowing the lifting frame 36 to lift the top plate 44.

[0040] like Figure 5 As shown, in this embodiment, the external vehicle microphone mounting base also includes a spring 2 37, and a spring 2 37 providing a reset force is arranged between the end of the positioning block 34 and the guide rod of the guide seat 35. The spring 2 37 provides a reset force for the positioning block 34 to ensure that the positioning block 34 can return to its initial position after the disassembly operation is completed.

[0041] like Figure 1-Figure 2 and Figure 9-10 As shown, in this embodiment, the external vehicle microphone mounting base also includes a suction cup 6, and an auxiliary mounting suction cup 6 is fixed to the bottom of the substrate 1 by glue. The suction cup 6 assists the substrate 1 to be fixed to the vehicle body through atmospheric pressure to enhance the overall stability of the device.

[0042] like Figure 9-10As shown, in this embodiment, the suction cup 6 also includes a release sleeve 601, an adjusting rod 61 and a sliding plug 62. A plurality of release sleeves 601 are arranged between the suction cup 6 and the inside of the substrate 1. A cavity is opened inside the release sleeve 601, and a thread is opened on the inner wall of the cavity. An adjusting rod 61 is threadedly arranged inside the release sleeve 601, and a sliding plug 62 adapted to the inner wall of the release sleeve 601 is arranged at the end of the adjusting rod 61. The sliding plug 62 is made of rubber material. The position of the sliding plug 62 is adjusted by rotating the adjusting rod 61 to increase or decrease the pressure inside the release sleeve 601, thereby changing the adsorption force of the suction cup 6, thereby assisting the installation of the adhesive sheet 11 on the substrate 1.

[0043] Before installation, check whether all components are intact, especially key components such as the adhesive sheet 11, suction cup 6, and vibration reduction part 2. Ensure that the microphone body 5, protective shell 4, base 3 and other components are clean and free of dust or foreign matter to avoid affecting the installation effect and equipment performance. Place the substrate 1 at the predetermined installation position, such as the outer body of the vehicle, and firmly adhere the substrate 1 to the surface of the vehicle body through the adhesive sheet 11. If additional fixing force is required, the suction cup 6 at the bottom of the substrate 1 can be used to increase the adsorption strength. By rotating the adjustment rod 61, the position of the slide plug 62 can be adjusted to change the adsorption force of the suction cup 6 to ensure that the substrate 1 is more firmly fixed to the vehicle body, ensure its levelness and stability, and avoid loosening or falling off due to improper installation. The first vibration reduction part 2 is installed on the extended end of the edge of the substrate 1. These vibration reduction parts 2 are elastically fixed. The spring 22 and the washer 23 are designed to reduce the vibration generated during the driving of the vehicle. A second vibration-damping part 2 is also provided at the bottom of the base 3 to further enhance the vibration-damping effect. The vibration-damping column 21 slides in the sleeve 201 and, through the action of the spring 22, can effectively absorb vibrations from different directions, thereby improving the stability and service life of the microphone. The insertion opening of the base 3 is used for subsequent disassembly and maintenance operations. Then, the threaded portion of the microphone body 5 is aligned with the threaded groove in the protective shell 4, and the microphone body 5 is rotated clockwise until it is fully screwed in and locked by the wedge block 42. At this time, the lower part of the microphone body 5 is in contact with the top plate 44, and the top plate 44 is connected to the inner bottom of the base 3 through another vibration-damping part 2, further increasing the stability of the system. Finally, ensure that the insertion opening at the lower part of the base 3 is in a closed state.

[0044] When disassembling, the limit lock 31 is unlocked to move the lock core away from the end of the sealing cover 301. At this time, the torsion springs 32 at both ends of the sealing cover 301 will change from a tightened state to a loose state, driving the sealing cover 301 to rotate and open around the hinge point. The opening action of the sealing cover 301 will drive the folding member 33 connected thereto to fold and rotate, thereby causing the positioning block 34 to slide forward along the guide rod of the guide seat 35. As the positioning block 34 slides, the hinge point between the rear part of the folding member 33 and the lifting frame 36 will gradually rise, causing the lifting frame 36 to move upward, and the rising action of the lifting frame 36 will directly act on The top plate 44 is lifted up by connecting the lower end of the top plate 44 with another vibration-damping part 2. When the top plate 44 rises, the contact block 45 thereon will contact the wedge block 42 in the protective shell 4, generating an inward pulling force, forcing the wedge block 42 to overcome the resistance of the spring three 43 and slide inward, thereby releasing the abutment state with the matching groove of the microphone body 5. When the wedge block 42 no longer abuts against the matching groove of the microphone body 5, the microphone body 5 can be rotated counterclockwise to unscrew it from the threaded groove of the protective shell 4. After completing this operation, the microphone body 5 can be easily taken out for easy replacement or maintenance.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
