[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0033] The switch assembly 100 of the embodiment of the utility model comprises a frame 1 , a first switch 2 , a second switch 3 and a pressing member 4 .

[0034] like Figure 1 As shown, the frame 1 may be a bracket structure, and the material of the frame 1 may be plastic, metal, etc. During assembly, the frame 1 may be directly mounted on a handlebar of a vehicle, etc., thereby providing a mounting base for the switch assembly 100 .

[0035] The first switch 2 and the second switch 3 are both disposed on the frame 1. The first switch 2 is used to generate a first sound effect when triggered, and the second switch 3 is used to generate a second sound effect when triggered. Figure 1 As shown, the first switch 2 and the second switch 3 can be fixed on the above-mentioned frame 1, and the first switch 2 and the second switch 3 can be arranged at intervals in the left and right directions, wherein the first switch 2 can be provided on a circuit for emitting a first sound effect, and the on and off of the circuit can be controlled by turning the first switch 2 on and off, thereby realizing the control of the emission and stopping of the first sound effect.

[0036] The second switch 3 may be arranged on a circuit for emitting the second sound effect. The on and off of the circuit may be controlled by turning the second switch 3 on and off, thereby controlling the emission and stopping of the second sound effect.

[0037] It should be noted that the first sound effect may be a prompt sound with a relatively low sound intensity, specifically a sound clip such as a human voice, a beeping sound, music, etc. The second sound effect may be a sound such as a whistle with a sound intensity higher than the first sound effect, and the sound categories of the first sound effect and the second sound effect may be selectively set according to the user's own needs.

[0038] The pressing member 4 includes a first triggering portion 41 and a second triggering portion 42 , and at least a portion of the pressing member 4 is adjustable relative to the frame 1 so that the first triggering portion 41 can trigger the first switch 2 and the second triggering portion 42 can trigger the second switch 3 .

[0039] For example, Figure 1 As shown, the first trigger part 41 and the second trigger part 42 can be integrally formed on the pressing member 4, and the first trigger part 41 and the second trigger part 42 can be in the form of buttons, and the first trigger part 41 and the second trigger part 42 can have a certain elasticity. When in use, the first trigger part 41 can be pressed, and the pressed first trigger part 41 can push the first switch 2, so that the first switch 2 can be closed, and then the first sound effect can be emitted.

[0040] Similarly, when in use, the second trigger portion 42 may be pressed, and the pressed second trigger portion 42 may push the second switch 3, thereby closing the second switch 3 and emitting the second sound effect.

[0041] The switch assembly 100 of the embodiment of the utility model is integrated with the function of starting the first sound effect and the second sound effect, thereby meeting the use needs of issuing a prompt sound and a horn, wherein the sound intensity of the prompt sound is relatively low, which can avoid disturbing passers-by while reminding them, and the two sound effects are independently triggered by the corresponding trigger parts and switches respectively, realizing the integration of the two trigger mechanisms on the switch assembly 100, and avoiding the situation of false triggering, and also allowing users to use different sound effects according to actual conditions, thereby improving the flexibility of using sound effect reminders.

[0042] In some embodiments, at least part of the pressing member 4 is swingable relative to the frame 1 around the swing axis, the first switch 2 is located between the second switch 3 and the swing axis, and the first trigger portion 41 is located between the second trigger portion 42 and the swing axis.

[0043] For example, Figure 1 As shown, the pressing member 4 can be directly rotatably assembled with the frame 1. In some other embodiments, the pressing member 4 can also be rotatably assembled with other parts of the vehicle. The swing axis can be regarded as the axis when the pressing member 4 swings relative to the frame 1, that is, the pressing member 4 will swing around the swing axis.

[0044] like Figure 1As shown, the pressing member 4 as a whole can swing from the lower left to the upper right, the above-mentioned swing axis can be located on the right side of the pressing member 4, and the first trigger part 41, the second trigger part 42, the first switch 2, and the second switch 3 can all be located on the left side of the swing axis.

[0045] In the left and right direction, the first trigger part 41 can be located between the second trigger part 42 and the swing axis, and the first switch 2 can be located between the second switch 3 and the swing axis. The first trigger part 41 and the first switch 2 can be arranged relative to each other in the up and down direction, and the second trigger part 42 and the second switch 3 can be arranged relative to each other in the up and down direction.

[0046] Therefore, when the pressing member 4 swings toward the lower left direction under the action of human power, the first trigger part 41 and the second trigger part 42 can respectively stop the first switch 2 and the second switch 3, thereby realizing the emission of the first sound effect and the second sound effect. This driving method of driving the pressing member 4 to swing improves the convenience of operation.

[0047] In some embodiments, the pressing member 4 is rotatably assembled with the frame 1, and the swing axis is located at the rotation connection between the pressing member 4 and the frame 1. Specifically, the pressing member 4 can be rotatably assembled with the frame 1 through a pivot, etc. The pivot can generally extend along the front-to-back direction, and the center axis of the pivot can be regarded as the swing axis. Thus, the pressing member 4 and the frame 1 can be integrated, and then the switch assembly 100 can be integrated and modularized.

[0048] In some embodiments, the pressing member 4 has an initial position, which is the position where the pressing member 4 is maintained when no operation is performed. Figure 1 As shown, at this time, the position of the pressing member 4 can be regarded as the initial position.

[0049] In the initial position, the distance between the first trigger portion 41 and the first switch 2 is smaller than the distance between the second trigger portion 42 and the second switch 3. Figure 1 As shown, in the initial position, the first trigger portion 41 and the first switch 2 may contact each other in the up-down direction, but the first trigger portion 41 may not have a stopping effect on the first switch 2, and the second trigger portion 42 and the second switch 3 may be spaced apart in the up-down direction.

[0050] Therefore, when the pressing member 4 is driven to approach the frame 1 by manual pressure, the triggering of the first switch 2 by the first trigger part 41 can lag behind the triggering of the second switch 3 by the second trigger part 42, thereby satisfying the need of only emitting the first sound effect when the pressing member 4 is lightly pressed, and emitting the second sound effect when the pressing member 4 is pressed hard.

[0051] In some embodiments, the switch assembly 100 includes an elastic member 5 , which is disposed between the pressing member 4 and the frame 1 , and the elastic member 5 is used to restore the pressing member 4 to an initial position.

[0052] For example, Figure 1 As shown, the elastic member 5 may be a spring, and the elastic member 5 may generally extend in the up-down direction and be assembled between the pressing member 4 and the frame 1, wherein the top end of the elastic member 5 may abut against the pressing member 4, and the bottom end of the elastic member 5 may abut against the frame 1. When the pressing member 4 is released by hand, the elastic potential energy of the elastic member 5 will be released, thereby driving the pressing member 4 to return to the above-mentioned initial position, meeting the need for repeated use of the pressing member 4.

[0053] In some embodiments, the elastic member 5 is sleeved on the outer peripheral side of the second triggering portion 42 and the second switch 3. Figure 1 As shown, the second trigger portion 42 can be cylindrical, and the elastic member 5 can be simultaneously mounted on the outer peripheral side of the second trigger portion 42 and the contact of the second switch 3, thereby enhancing the limiting effect on the elastic member 5 and also facilitating improving the structural stability of the elastic member 5 in compression or extension.

[0054] In some embodiments, the switch assembly 100 includes a cover 6 , which is disposed on the outer peripheral side of the second switch 3 , one end of the elastic member 5 abuts against the pressing member 4 , and the other end of the elastic member 5 abuts against the cover 6 .

[0055] For example, Figure 1 As shown, the cover body 6 can be a cap-shaped structure, and the cover body 6 can be fixed on the frame 1, and the fixing method of the cover body 6 can be threaded assembly, buckle fixing, etc. The second switch 3 can be generally located in the cover body 6, and the cover body 6 can play a waterproof and sealing effect, thereby improving the protection of the second switch 3.

[0056] The top end of the elastic member 5 can abut against the pressing member 4, and the bottom end of the elastic member 5 can abut against the cover body 6, thereby preventing the elastic member 5 from easily touching the second switch 3 when being pressed. The cover body 6 can isolate the elastic member 5 from the second switch 3, and also enhance the convenience of assembling the elastic member 5.

[0057] The voice control system of the embodiment of the utility model is described below.

[0058] like Figure 2 As shown, the sound control system of the embodiment of the utility model includes a first sound component 200 and a second sound component 300. The first sound component 200 is connected to the first switch 2 and is used to emit a first sound effect. The second sound component 300 is connected to the second switch 3 and is used to emit a second sound effect.

[0059] For example, the first sound-emitting component 200 can be an electronic speaker, a sound effect sound-emitting device, etc. The first sound-emitting component 200 can be connected to the first switch 2 through a wire, etc. When the first switch 2 is closed, the first sound-emitting component 200 will be powered on and emit a first sound effect. The second sound-emitting component 300 can be a horn device, and the second sound-emitting component 300 can also be connected to the second switch 3 through a wire, etc. When the second switch 3 is closed, the second sound-emitting component 300 will be powered on and emit a second sound effect. Thus, the use needs of emitting a prompt sound and a whistle are met.

[0060] In some embodiments, Figure 2 As shown, the voice control system includes a temperature sensor 400 and a central control device 500, wherein the central control device 500 may be a central control of an instrument, and in some other embodiments, the central control device 500 may also be a VCU, a motor controller, an ECU, etc. The temperature sensor 400 may be an NTC module, and the temperature sensor 400 may be installed at the battery of the vehicle, so as to realize real-time monitoring of the battery temperature.

[0061] The first sound component 200, the second sound component 300, and the temperature sensor 400 are all electrically connected to the central control device 500, and the central control device 500 is used to control the second sound component 300 to emit a third sound effect when the temperature monitored by the temperature sensor 400 is higher than the temperature threshold.

[0062] For example, the temperature threshold may be the upper temperature limit allowed for normal operation of the battery. If the temperature of the battery detected by the temperature sensor 400 is higher than the upper temperature limit, it indicates that the battery is at risk of thermal runaway or thermal diffusion. When the central control device 500 receives the high temperature information detected by the temperature sensor 400, the central control device 500 may control the second sound component 300 to emit a third sound effect, which may be an alarm sound, thereby promptly reminding the user.

[0063] It should be noted that both the second sound effect and the third sound effect are emitted by the second sound-emitting component 300, thereby realizing the integrated arrangement of the battery temperature alarm function in the horn device (the second sound-emitting component 300), which is beneficial to simplify the overall vehicle components, thereby playing a role in improving production efficiency and reducing costs.

[0064] In some embodiments, Figure 2 As shown, the first sound emitting component 200 can be integrated in the central control device 500 , and the second sound emitting component 300 can be arranged independently of the central control device 500 .

[0065] In some embodiments, when the measuring point is 1m away from the sound source, the sound intensity of the first sound effect is 55dB to 62dB. For example, the sound source for emitting the first sound effect can be arranged on the instrument of the vehicle, and the measuring point can be regarded as the placement position of the instrument for measuring the decibel of the sound. When the measuring point is 1m away from the sound source, the measured sound intensity can be controlled within the range of 55dB to 62dB, specifically 55dB, 56dB, 57dB, 58dB, 60dB, 61dB, 62dB. This meets the need to remind passers-by and avoids the situation where the sound intensity of the first sound effect is too high.

[0066] In some embodiments, when the measuring point is 2m away from the front of the vehicle and 1.2m above the ground, the sound intensity of the second sound effect measured at the measuring point may be 75dB to 100dB, specifically 75dB, 76dB, 77dB, 78dB, 80dB, 90dB, 100dB, etc., thereby meeting the use requirements of whistle.

[0067] In some embodiments, when the measuring point is 2 meters away from the center of the vehicle body and 1.2 meters above the ground, the sound intensity of the third sound effect measured at the measuring point is not less than 85 dB, and can be 85 dB, 86 dB, 87 dB, 90 dB, 100 dB, etc., thereby meeting the use needs of the alarm prompt.

[0068] The following describes a vehicle according to an embodiment of the present invention.

[0069] The vehicle of the embodiment of the utility model includes a voice control system, which can be a voice control system as described in any of the above embodiments. The vehicle can be a two-wheeled vehicle such as an electric motorcycle or an electric bicycle, or a tricycle, or other vehicles that need to be equipped with a voice control system.

[0070] A specific example of a vehicle according to an embodiment of the present utility model is described below.

[0071] The vehicle of the embodiment of the utility model may be an electric vehicle, and the vehicle includes a switch assembly 100 , a first sound-emitting component 200 , a second sound-emitting component 300 , a temperature sensor 400 and a central control device 500 .

[0072] The central control device 500 may be a communication digital analog signal or a throttle voltage value receiving device, and the central control device 500 is not limited to external central control receiving devices such as a meter, VCU, controller, ECU, etc. In this example, the central control device 500 is described as a meter.

[0073] The instrument of an electric vehicle may be equipped with an electronic horn or a sound-generating device. The user triggers switch a (which can be regarded as the first switch 2) by lightly pressing the pressing part 4 of the switch assembly 100, outputting a signal to the instrument. The electronic horn of the instrument will work (delay of 0.3s) and emit a prompt sound. The prompt sound here is different from the ordinary whistle sound and can be customized through the APP.

[0074] After triggering switch a, the user continues to press the pressing part 4 of the switch assembly 100 until he feels the feedback of the triggering of switch b. At this time, both switch a and switch b are turned on and output signals to the instrument. The instrument determines the priority of switch a and switch b, and then drives the horn device (which can be regarded as the second sound-emitting component 300) to work and emit a whistle sound.

[0075] The battery NTC module (which can be regarded as a temperature sensor 400) sends a signal to the instrument when the battery temperature exceeds the set value. The instrument outputs power, drives the horn device to work, and issues a battery over-temperature alarm. After the battery over-temperature alarm, the pressing member 4 of the switch assembly 100 triggers the failure of the functions of the first switch 2 and the second switch 3. At this time, the vehicle will continue to emit an alarm sound, and the power of the whole vehicle will be cut off. When the battery temperature is lower than the set value of the over-temperature alarm, the alarm sound stops, the pressing member 4 triggers the function of the first switch 2 and the second switch 3 to resume, and the power of the whole vehicle is restored.

[0076] The above priority judgment method - battery over-temperature alarm (third sound effect) is higher than whistle sound (second sound effect), and whistle sound is higher than prompt sound effect (first sound effect), as follows:

[0077] During normal use of the vehicle by the user, the user lightly presses the pressing member 4 of the switch assembly 100. At this time, switch a is triggered and switch b is not triggered. The instrument receives the triggering signal of switch a and emits a prompt sound (first sound effect) after a delay of 0.3s. The time for lightly pressing the pressing member 4 of the switch assembly 100 to emit the prompt sound must be greater than 0.3s, otherwise the instrument will determine that the trigger is invalid and will not emit the prompt sound. In addition, the delay time threshold of 0.3s can be adjusted according to actual needs.

[0078] ② The user presses the pressing member 4 of the switch assembly 100 hard, and the switches a and b are triggered successively. The instrument receives the triggering signals of switches a and b successively in a short time (within 0.3s). When the instrument receives the triggering signal of switch b, it immediately emits a whistle sound.

[0079] ③ The user first presses the switch assembly 100 lightly, and when the prompt sound is emitted, the user continues to press the pressing member 4 of the switch assembly 100 again. At this time, the switch b is also triggered, the prompt sound effect will be immediately turned off, and a whistle sound (second sound effect) will be emitted immediately.

[0080] ④ In any case, when the instrument receives a battery over-temperature signal, it can only issue a battery over-temperature alarm, and the function of the pressing member 4 of the switch assembly 100 triggering the first switch 2 and the second switch 3 will become invalid; only when the battery temperature is less than the set temperature threshold, the battery over-temperature alarm will be turned off, and the function of the pressing member 4 of the switch assembly 100 triggering the first switch 2 and the second switch 3 will return to normal.

[0081] The vehicle of the embodiment of the utility model has the following beneficial effects: ① In the electric two-wheeled vehicle industry, the battery temperature alarm function is integrated into the horn device through the control of the instrument (central control device); ② A driving reminder sound effect is added to two-wheeled vehicles such as electric vehicles to remind the surrounding people of oncoming vehicles; ③ A single-press pressing part can realize the control of both the horn and the reminder sound effects; ④ Two switches are installed side by side on the frame of the switch assembly. When the button is pressed, the two switches are triggered successively, and the two function controls of the horn and the reminder sound are realized respectively.

[0082] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
