Description

Technical Field

[0001] The utility model relates to the technical field of warning circuits and equipment, in particular to an additional gear position voice prompt system. Background Art

[0002] Sightseeing buses operating in scenic areas usually need to have a voice prompt function, which is different from the vehicle's own horn. Before the sightseeing bus starts, it is usually necessary to remind the surrounding and passengers that the vehicle is about to start. Some existing sightseeing buses have the above function, but some sightseeing buses do not provide the above function. If the driver relies on pressing the vehicle horn to give a prompt, some passengers and tourists may not understand the driver's intention well, so the effect is poor. If you want to add the above function, it is extremely inconvenient to add a new module to the original vehicle circuit board. Utility Model Content

[0003] In order to solve the problem that it is inconvenient to add a voice prompt system to some of the above sightseeing vehicles, the utility model provides an additional gear position voice prompt system.

[0004] The technical solution of this utility model is as follows:

[0005] An additional gear voice prompt system includes a control module, wherein a first port of the control module is grounded, a second port is connected to an output end of a photoelectric switch, a third port is connected to an output voltage via a base oscillation resistor, a fourth port is connected to a speaker via an amplifier circuit, and the speaker is also connected to the output voltage, and a fifth port of the control module is directly connected to the output voltage;

[0006] The output voltage is also connected to the positive input terminal of the photoelectric switch, and the negative input terminal of the photoelectric switch is grounded;

[0007] The photoelectric switch is arranged on one side of the gear lever, and the orientation direction of the photoelectric switch is perpendicular to the rotation plane of the gear lever.

[0008] Different from the method of adding a voice prompt system to the vehicle circuit board, this device can complete the above-mentioned enhancement function by monitoring the gear lever through a photoelectric switch and a control module. It is not limited to the type of vehicle and can be installed as long as it has a gear lever, and there is no need to modify the original vehicle circuit system.

[0009] In order to ensure that the vehicle can be prompted when it moves, two photoelectric switches are set in parallel, and they correspond to the forward and reverse gear positions of the gear lever respectively. Sightseeing vehicles usually only have two gears, forward and reverse, so only these two gears need to be monitored to ensure that a prompt warning is issued when the vehicle moves.

[0010] As a preferred solution, the gear lever is a rod-type gear lever, and a reflective sheet is provided on the symmetrical side of the photoelectric switch, and there is no shielding between the photoelectric switch and the reflective sheet except the rod-type gear lever. The rod-type gear lever is usually a cylindrical structure with poor reflective effect, so it is necessary to make changes to its characteristics.

[0011] As another preferred solution, the gear lever is a push-button gear lever, and a reflective sheet is provided on the side of the push-button gear lever close to the photoelectric switch, and there is no shielding between the photoelectric switch and the reflective sheet except the push-button gear lever. Different from the conventional rod-type gear lever, it needs to be changed according to its characteristics.

[0012] In order to ensure the normal use of the photoelectric switch, the reflective sheet is arranged perpendicular to the direction of the photoelectric switch.

[0013] In order to facilitate the replacement of the reflective sheet, the reflective sheet is fixed by pasting, so that the reflective sheet can be quickly replaced in time after the effect of the reflective sheet deteriorates.

[0014] As a preferred solution, the control module is HFC5212.

[0015] As a preferred solution, the output voltage is 12V.

[0016] In order to avoid sending out a false signal, the gear lever can trigger the photoelectric switch only when the gear lever reaches the forward gear or the reverse gear.

[0017] The beneficial effect of the utility model is that the utility model is an additional gear voice prompt system, which can add an additional gear voice prompt function without affecting the original circuit system of the vehicle, and the monitoring method is to monitor the gear handle through a photoelectric switch, which is not limited by the vehicle specifications. As long as it has a gear handle, this solution can be used to increase the function, and the above-mentioned components are all exposed to the outside for easy maintenance.

[0027] like Figure 1 An additional gear position voice prompt system shown includes a control module, and the control module is HFC5212, which can be directly obtained through purchase.

[0028] Afterwards, if Figure 1 As shown, the first port of the control module is grounded, the second port of the control module is connected to the output end of the photoelectric switch 1, and the above-mentioned output end is the signal output end of the photoelectric switch 1, that is, the second port can input the output signal of the photoelectric switch 1 and respond, and then, the third port of the control module is connected to the output voltage through the base oscillation resistor, and the resistance value of the above-mentioned base oscillation resistor can be changed, and after the change, the tone of the voice can be changed accordingly. The principle is the existing technology, so it will not be repeated. The key point is that the fourth port of the control module is connected to the speaker through the amplification circuit. The function of the speaker is to issue a reminder voice, which can be "The vehicle is started, please stand firmly and hold it well" "The vehicle is started, please pay attention" and the like. It is similar to voice information, which can achieve the purpose of reminding passengers and tourists, and in the above structure, the speaker is also connected to the output voltage to ensure that a complete power supply circuit can be formed and drive it to function. Finally, the fifth port of the control module is directly connected to the output voltage, and generally, the output voltage is 12v, which can drive the speaker to make a sound, and can also power other components, and can also power the photoelectric switch 1, and the above output voltage can be obtained by connecting to a battery. If the sightseeing car itself has a 12v voltage, it can be directly connected to it. If not, an external battery is required, and it needs to be charged according to demand.

[0029] In the above structure, it should be noted that the output voltage is also connected to the positive input terminal of the photoelectric switch 1, and the negative input terminal of the photoelectric switch 1 is grounded to ensure that a complete circuit loop can be formed and the photoelectric switch 1 can function.

[0030] like Figure 2-5As shown, unlike the conventional monitoring method through circuits, the photoelectric switch 1 of the present device is arranged on one side of the gear handle, and the direction of the photoelectric switch 1 is perpendicular to the rotation plane of the gear handle. After the gear handle rotates and switches positions, the photoelectric switch 1 can be triggered to send out an output signal, and finally the speaker sends out a reminder voice.

[0031] In the above system, in order to avoid sending out an erroneous signal, the gear lever can only trigger the photoelectric switch 1 when the gear lever reaches the forward gear or the reverse gear. For this reason, two photoelectric switches 1 are generally required to be provided, one for monitoring the forward and the other for monitoring the reverse.

[0032] That is Figure 2 , 5 As shown, in order to ensure that the vehicle can be prompted when it moves, the photoelectric switch 1 is provided with two in parallel, and corresponds to the forward gear and reverse gear positions of the gear lever respectively. Sightseeing vehicles usually only have two gears, forward and reverse, so only these two gears need to be monitored to ensure that a prompt warning is issued when the vehicle moves. In the P gear, the vehicle cannot move, so no monitoring is required.

[0033] The above system can be used to achieve the above-mentioned lifting function. Different from adding a voice prompt system to the vehicle circuit board, the device can complete the above-mentioned lifting function by monitoring the gear lever through the photoelectric switch 1 in cooperation with the control module, and is not limited to the vehicle type. As long as it has a gear lever, it can be installed, and there is no need to modify the original vehicle circuit system. And it does not need to rely on any function on the original vehicle, it only needs to have a gear lever that can be switched.

[0034] Generally speaking, sightseeing buses have two main ways of switching gears, namely button type and lever type.

[0035] like Figure 5 As shown, the gear lever is a rod-type gear lever 3, and a reflector 2 is provided on the symmetrical side of the photoelectric switch 1, and there is no obstruction between the photoelectric switch 1 and the reflector 2 except the rod-type gear lever 3. The rod-type gear lever 3 is usually a cylindrical structure with poor reflective effect, so it is necessary to make changes to its characteristics. Since the rod-type gear lever 3 is a cylindrical structure, it is inconvenient to cooperate with the photoelectric switch 1, so it is necessary to set a reflector 2 on its symmetrical side. When it is located between the photoelectric switch 1 and the reflector 2, it can be judged that it has reached the corresponding gear position, and a corresponding reminder voice needs to be issued.

[0036] And as Figure 2-4As shown, as another embodiment, the gear lever is a push-button gear lever 4, and a reflective sheet 2 is provided on the side of the push-button gear lever 4 close to the photoelectric switch 1, and there is no shielding between the photoelectric switch 1 and the reflective sheet 2 except the push-button gear lever 4. Different from the conventional rod-type gear lever 3, it needs to be changed according to its characteristics. The side of the push-button gear lever 4 is generally a plane, so the reflective sheet 2 can be directly pasted, and the reflective sheet 2 does not need to be set in a symmetrical position. It only needs to align the photoelectric switch 1 with the reflective sheet 2 to determine whether it has reached the corresponding gear position, which is slightly different from the rod-type gear lever 3.

[0037] In view of the above two situations, in order to ensure the normal use of the photoelectric switch 1, the reflective sheet 2 is arranged perpendicular to the direction of the photoelectric switch 1. To this end, two installation methods of the reflective sheet 2 need to be set.

[0038] Finally, in order to facilitate the replacement of the reflective sheet 2, the reflective sheet 2 is fixed by pasting, so that the reflective sheet 2 can be quickly replaced in time after the effect of the reflective sheet 2 deteriorates.
