Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a turn signal delay-off device for electric vehicles. Background Technology

[0002] The electric vehicles (also known as handlebar vehicles) referred to in this application mainly refer to two-wheeled or three-wheeled electric bicycles, electric motorcycles, etc. Electric vehicles are equipped with turn signals. In terms of turn signal control, they are generally set to traditional handlebar switches, which have the characteristics of low price and simple operation. However, these traditional switches have some hidden safety hazards when operating.

[0003] Because traditional turn signals cannot reset automatically and require external force to reset, it is easy to forget to turn the switch back to its original position when turning or changing lanes, causing the left (or right) turn signal to remain on, which can lead to misjudgment by vehicles behind and greatly increase the risk of rear-end collisions.

[0004] The above-mentioned technical solutions are widely used because they are based on the consideration of achieving steering function and cost pressure.

[0005] However, the aforementioned technical problems exist. In order to solve the problem of not being able to automatically turn off, and at the same time to help control costs, the applicant has researched a turn signal delay-off device for electric vehicles. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a turn signal delay-off device for electric vehicles, which can automatically turn off the turn signals while also helping to control costs.

[0007] Compared to existing technologies, this utility model proposes a turn signal delay-off device for electric vehicles, including a turn signal, a turn switch, and a controller. The turn switch is a self-resetting toggle switch; when in use, toggling the switch button activates the switch and sends a signal, and when the switch is released, it automatically resets and disconnects the signal. It also includes a level converter, electrically connected to the turn switch and the controller. The level signal generated by the turn switch is converted into a low-level signal by the level converter and sent to the controller. When the turn switch is pushed to the left to generate a first level signal, the controller activates the left turn signal; when the turn switch is pushed to the right to generate a second level signal, the controller activates the right turn signal. The controller has a timer; when it receives the level signal generated by the turn switch, the timer starts counting; when the timer ends and no further level signal is received from the turn switch, the controller deactivates the turn signal.

[0008] As an improvement, a hazard light switch is also included, which is electrically connected to a level converter. The level signal generated by the hazard light switch is converted into a low-level signal by the level converter and sent to the controller. When the controller receives the aforementioned low-level signal, it simultaneously controls the left turn signal and the right turn signal to flash.

[0009] As an improvement, it also includes a first digital-to-analog converter and a second digital-to-analog converter, which are electrically connected to the controller respectively. The first digital-to-analog converter converts the first level signal into a left turn analog signal, and the second digital-to-analog converter converts the second level signal into a right turn analog signal.

[0010] As an improvement, it also includes a left-turn power amplifier and a right-turn power amplifier, with a first digital-to-analog converter electrically connected to the left-turn power amplifier, a second digital-to-analog converter electrically connected to the right-turn power amplifier, the left-turn power amplifier electrically connected to the left turn signal, and the right-turn power amplifier electrically connected to the right turn signal.

[0011] As an improvement, a flashing controller is also included. The controller outputs flashing digital signals to a first digital-to-analog converter and a second digital-to-analog converter. The flashing digital signals are converted by the first digital-to-analog converter and the second digital-to-analog converter to form left turn analog signals and right turn analog signals to flash the turn signals.

[0012] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0013] In this disclosure, the user toggles a self-resetting toggle switch to send a first-level signal / second-level signal to the controller. When the user releases the toggle switch, it resets and disconnects the signal. Upon receiving the first-level signal / second-level signal, the controller activates the corresponding turn signal. The controller also has a timer. When the first-level signal / second-level signal is received, the timer starts counting. When the timer ends and no further first-level signal / second-level signal is received, the controller turns off the turn signal. Therefore, the turn signal can be automatically turned off, and the structure is simple, which is beneficial for cost control. Attached Figure Description

[0014] Figure 1 This is a block diagram of a turn signal delay-off device for an electric vehicle. Detailed Implementation

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0016] The present invention will now be described in further detail:

[0017] like Figure 1 The diagram shows a turn signal delay-off device for an electric vehicle, comprising a turn signal, a turn switch, and a controller. The turn switch is a self-resetting toggle switch; when in use, toggling the switch button activates the switch and sends a signal, and when the switch is released, it automatically resets and disconnects the signal. The device also includes a level converter, electrically connected to the turn switch and the controller. The level signal generated by the turn switch is converted into a low-level signal by the level converter and sent to the controller. When the turn switch is pushed to the left, generating a first level signal, the controller activates the left turn signal; when the turn switch is pushed to the right, generating a second level signal, the controller activates the right turn signal. The controller has a timer; when it receives a level signal from the turn switch, the timer starts counting; when the timer ends and no further level signal is received from the turn switch, the controller deactivates the turn signal.

[0018] It is worth noting that due to the use of self-resetting toggle switches, the signals generated in this application environment are mostly jog signals, or pulse signals. Therefore, the isolation and conversion by the level converter is beneficial for both isolation protection and interference prevention, which helps to achieve signal output to the controller and ensure reliability.

[0019] In some embodiments, a hazard light switch is also included, which is electrically connected to a level converter. The level signal generated by the hazard light switch is converted into a low-level signal by the level converter and sent to the controller. When the controller receives the aforementioned low-level signal, it simultaneously controls the left turn signal and the right turn signal to flash.

[0020] In practical use, turn signals are generally used to illuminate in a flashing manner. Therefore, this disclosure also includes a flashing controller. The controller outputs flashing digital signals to a first digital-to-analog converter (DAC) and a second DAC. The flashing digital signals are converted by the first DAC and the second DAC to form left turn analog signals and right turn analog signals to illuminate the turn signals in a flashing manner. The flashing controller can be a separate chip or a program implemented within the controller.

[0021] Of course, when the left turn signal flashes or the right turn signal flashes, it is also achieved by converting the digital signal into an analog signal. Specifically, it also includes a first digital-to-analog converter and a second digital-to-analog converter. The first digital-to-analog converter and the second digital-to-analog converter are electrically connected to the controller. The first digital-to-analog converter converts the first level signal into a left turn analog signal, and the second digital-to-analog converter converts the second level signal into a right turn analog signal.

[0022] In some embodiments, a left-turn power amplifier and a right-turn power amplifier are further included. A first digital-to-analog converter is electrically connected to the left-turn power amplifier, and a second digital-to-analog converter is electrically connected to the right-turn power amplifier. The left-turn power amplifier is electrically connected to the left turn signal, and the right-turn power amplifier is electrically connected to the right turn signal. The left-turn power amplifier and the right-turn power amplifier are, for example, transistors, MOSFETs, etc., to prevent interference and reliably illuminate the turn signals.

[0023] Both the controller and the blink controller can be integrated using, for example, a 51 microcontroller. That is, the functions of the timer and the blink controller can be implemented by programming the 51 microcontroller, which is the lowest cost.

[0024] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model patent are included within the scope of protection of this utility model patent.
