Description

Technical Field

[0001] The present application relates to an in-vehicle audio, and more specifically, to a self-checkable in-vehicle intelligent audio manager. Background Art

[0002] The in-vehicle intelligent audio management system is a software system specifically designed for the car audio system, aiming to provide a more convenient and intelligent audio management experience. The in-vehicle intelligent audio management system collects audio signals and control signal inputs through an audio integrated controller, and after data operation and processing, outputs different audio signals to achieve in-vehicle and out-of-vehicle voice broadcasts and driver alarm functions. However, during long-term use of the in-vehicle audio manager, due to vehicle bumps, the plugs may become loose, poorly contacted, or even fall off. The driver cannot immediately know the connection status of the in-vehicle audio manager's lines, which affects the use. Therefore, a self-check system needs to be designed for the line connection of the in-vehicle audio manager so that the driver can timely learn about the line connection status of the in-vehicle audio manager and optimize the use experience. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a self-checkable in-vehicle intelligent audio manager, and its advantage is that this in-vehicle intelligent audio manager can self-check whether the plugs inserted into each transmission interface are loose or fallen off, and give an alarm feedback on the detection situation.

[0004] To achieve the above purpose, the present utility model provides the following technical solution: A self-checkable in-vehicle intelligent audio manager, including a plug-in board, a transmission interface arranged on the plug-in board, and a plug inserted into the transmission interface. A feedback board for pressing against the transmission interface and applying pressure is hinged on the plug. A torsion spring is arranged on the hinged section of the feedback board. The feedback board is arranged at an acute angle with the length direction of the plug away from the end under the action of the torsion spring. A receiving groove for accommodating the feedback board is opened on the plug. A pressure sensing board for abutting against the pressure of the feedback board is arranged on the inner side wall of the transmission interface. The pressure sensing board is electrically connected to the inside of the plug-in board. A warning device is arranged on the plug-in board.

[0005] By adopting the above technical solution, when using the in-vehicle intelligent audio manager, the corresponding plug can be inserted into the corresponding transmission interface. As the plug is inserted into the transmission interface, the feedback plate hinged on the plug gradually approaches the side wall of the plug, and the torsion spring is also gradually deformed and increases the deflecting force applied to the feedback plate away from the plug. After the plug is properly fitted with the transmission interface, the feedback plate abuts against the pressure sensing plate under the action of the torsion spring. The pressure sensing plate transmits the signal to the plug-in board under the action of the abutting pressure of the feedback plate, and the plug-in board transmits the signal to the warning device, and the warning device gives a prompt that the plug is normally inserted into the transmission interface; when the plug is pulled out from the transmission interface, the feedback plate disengages from the pressure sensing plate and rotates away from the side wall of the plug under the action of the torsion spring. The pressure sensing plate transmits the signal to the plug-in board without any force, and the plug-in board transmits the signal to the warning device, so that the warning device gives an alarm.

[0006] In summary, through the interaction of the torsion spring on the plug, the feedback plate and the pressure sensing plate on the transmission interface, the pressure sensing plate transmits the signal to the plug-in board under the action of the abutting force of the feedback plate, and the alarm device gives a prompt, so that the in-vehicle intelligent audio manager can automatically detect whether the plugs inserted into each transmission interface are loose or fallen off, and feed back the detection situation by alarm.

[0007] The present utility model is further configured as: a protrusion for abutting against the pressure sensing plate is provided at one end of the feedback plate away from its hinge.

[0008] By adopting the above technical solution, with the setting of the protrusion, under the torsion spring of the same model, the feedback plate abuts against the pressure sensing plate through the protrusion to further increase the rotation angle, and the acting force applied by the torsion spring is greater.

[0009] The present utility model is further configured as: the extending direction of the protrusion is parallel to the rotation axis of the feedback plate, and the cross section of the protrusion is arc-shaped.

[0010] By adopting the above technical solution, the cross section of the protrusion is arc-shaped, which can play a transitional role in the process of the feedback plate entering the transmission interface, facilitating the protrusion to enter the inside of the transmission interface.

[0011] The present utility model is further configured as: a limiting block is provided on the side wall of one end of the plug close to the transmission interface, and a limiting groove matching with the limiting block is provided on the transmission interface.

[0012] By adopting the above technical solution, the setting of the limiting block and the limiting groove can play a guiding role when the plug is inserted into the transmission interface, so as to ensure the alignment of the feedback plate and the pressure sensing plate.

[0013] The present utility model is further configured as: an anti-slip strip is provided on the side wall of one end of the plug away from the transmission interface.

[0014] By adopting the above technical solution, the anti-slip strip is provided to increase the friction between the operator and the plug when the operator operates the plug, avoiding the slipping phenomenon during the plugging and unplugging of the plug.

[0015] The present utility model is further configured as: the warning device includes a warning light and a buzzer.

[0016] By adopting the above technical solution, when the feedback plate abuts against the pressure sensing plate, the warning light emits light and the buzzer is in a static state; when the feedback plate disengages from the pressure sensing plate, the warning light goes out and the buzzer emits a beep.

[0017] In summary, the present utility model has the following advantages:

[0018] 1. Through the mutual cooperation of the torsion spring on the plug, the feedback plate and the pressure sensing plate on the transmission interface, the pressure sensing plate transmits a signal to the plug-in board under the action of the abutting force of the feedback plate, and is prompted by the alarm device, so as to achieve that the in-vehicle intelligent audio manager can automatically detect whether the plugs inserted into each transmission interface are loose or fallen off, and give an alarm feedback on the detection situation.

[0019] 2. Under the same type of torsion spring, the feedback plate further increases the rotation angle by abutting against the pressure sensing plate through the protrusion, and the acting force applied by the torsion spring is greater.

[0020] 3. When the feedback plate abuts against the pressure sensing plate, the warning light emits light and the buzzer is in a static state; when the feedback plate disengages from the pressure sensing plate, the warning light goes out and the buzzer emits a beep.

[0025] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0026] An in-vehicle intelligent audio manager capable of self-checking, such asFigure 1 , 2 As shown in 2 , it includes a plug-in board 1, a transmission interface 2 installed on the plug-in board 1, and a plug 3 inserted into the transmission interface 2. A feedback board 4 is hingedly installed on the plug 3 for pressing against the transmission interface 2 and applying pressure. A torsion spring 5 is installed on the hinged section of the feedback board 4. Under the action of the torsion spring 5, the feedback board 4 is arranged at an acute angle with the length direction of the plug 3 away from the end. A receiving groove 6 for accommodating the feedback board 4 is formed on the plug 3. A pressure sensing board 7 for abutting against the pressure of the feedback board 4 is installed on the inner side wall of the transmission interface 2. The pressure sensing board 7 is electrically connected to the inside of the plug-in board 1. A warning device is installed on the plug-in board 1.

[0027] Furthermore, the warning device includes a warning light 8 and a buzzer 9. When the feedback board 4 presses against the pressure sensing board 7, the warning light 8 emits light and the buzzer 9 is in a static state; when the feedback board 4 disengages from the pressure sensing board 7, the warning light 8 goes out and the buzzer 9 emits a beep.

[0028] As Figure 2 , 3 As shown in 3 , a protrusion 10 for pressing against the pressure sensing board 7 is fixed at one end of the feedback board 4 away from its hinge. Under the same type of torsion spring 5, the feedback board 4 presses against the pressure sensing board 7 through the protrusion 10, further increasing the rotation angle, and the acting force applied by the torsion spring 5 is greater.

[0029] Furthermore, the extending direction of the protrusion 10 is parallel to the rotation axis of the feedback board 4, and the cross-section of the protrusion 10 is arc-shaped, which can play a transitional role during the process of the feedback board 4 entering the transmission interface 2, facilitating the entry of the protrusion 10 into the inside of the transmission interface 2.

[0030] As Figure 2 , 3 As shown in 3 , a limiting block is arranged on the side wall of one end of the plug 3 close to the transmission interface 2, and a limiting groove 11 matching the limiting block is arranged on the transmission interface 2. It plays a guiding role when the plug 3 is inserted into the transmission interface 2, thus ensuring the alignment of the feedback board 4 and the pressure sensing board 7.

[0031] Furthermore, a plurality of anti-slip strips 12 extend from the side wall of one end of the plug 3 away from the transmission interface 2, which can increase the friction between the operator and the plug 3 when the operator operates the plug 3, avoiding the phenomenon of slipping when plugging and unplugging the plug 3.

[0032] The working process and beneficial effects of the present utility model are as follows: When using the in-vehicle intelligent audio manager, the corresponding plug 3 can be inserted into the corresponding transmission interface 2. As the plug 3 is inserted into the transmission interface 2, the feedback plate 4 hinged on the plug 3 gradually approaches the side wall of the plug 3, and the torsion spring 5 also gradually deforms and increases the deflecting force exerted on the feedback plate 4 away from the plug 3. After the plug 3 is properly matched with the transmission interface 2, the feedback plate 4 abuts against the pressure sensing plate 7 under the action of the torsion spring 5. The pressure sensing plate 7 transmits the signal to the plug-in board 1 under the action of the abutting pressure of the feedback plate 4, and the plug-in board 1 transmits the signal to the warning device, and the warning device gives a prompt that the plug 3 is normally plugged into the transmission interface 2. When the plug 3 is pulled out from the transmission interface 2, the feedback plate 4 disengages from the pressure sensing plate 7 and rotates away from the side wall of the plug 3 under the action of the torsion spring 5. The pressure sensing plate 7 transmits the signal to the plug-in board 1 without force, and the plug-in board 1 transmits the signal to the warning device, causing the warning device to give an alarm.

[0033] In summary, through the interaction of the torsion spring 5 on the plug 3, the feedback plate 4 and the pressure sensing plate 7 on the transmission interface 2, the pressure sensing plate 7 transmits the signal to the plug-in board 1 under the action of the abutting force of the feedback plate 4, and the warning device gives a prompt, so as to achieve that the in-vehicle intelligent audio manager can automatically detect whether the plugs 3 inserted into each transmission interface are loose or fallen off, and give an alarm feedback on the detection situation.

[0034] The above are only the preferred embodiments of the present utility model, and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
