Since the foot pedal can be pedaled with any force and depth, the vehicle is prone to rapid speed increase during driving, resulting in frequent braking after rapid acceleration.

[0042] Therefore, there is an urgent need for a device that can limit the speed and force of the foot pedal to optimize the power output of the vehicle, reduce power consumption, and improve driving safety and energy efficiency.
[0043] Three, based on the above problems, the utility model particularly provides a technical scheme for solving the above problems, and the technical scheme, working principle and technical effect of the utility model will be described in detail below in combination with specific embodiments.
[0044] Embodiment one
[0045] Please refer to Figs. 1 to 4 The electronic throttle limiter provided by the embodiment can reduce power loss.
[0046] The top end of the bottom plate 1 is also fixedly provided with two side seats 4, and the two side seats 4 and the pedal 3 are connected through a rotating plate 5. An electronic limiting mechanism is arranged between the side seat 4 and the rotating plate 5.
[0047] The specific structure of the electronic limiting mechanism is as follows: a side groove 7 is formed in the adjacent side of the two side seats 4, and the rotating plate 5 is fixedly connected with a movable shaft 10 at both ends thereof close to the side seat 4, and the movable shaft 10 extends into the side groove 7 of the corresponding side.
[0048] One end of the side groove 7 is fixedly connected with an electric telescopic rod 9, and the outside of the movable shaft 10 is rotatably connected with an external sleeve 11, and the telescopic end of the electric telescopic rod 9 is fixedly connected with the external sleeve 11.
[0049] In this way, when the electric telescopic rod 9 is telescoped, the movable shaft 10 can be driven to move in the side groove 7 through the external sleeve 11, so as to limit the depression of the pedal 3.
[0050] In addition, a resistance plate 12 is fixedly arranged on the inner side wall of the side groove 7, and the end of the movable shaft 10 is slidably connected with the resistance plate 12. The resistance plate 12 is used for monitoring the moving speed of the movable shaft 10, and converting the speed change into current change.
[0051] The electric telescopic rod 9 is connected with a controller (not shown in the figure), the resistance plate 12 is connected with a current sensor (not shown in the figure), and the controller and the current sensor are electrically connected.
[0052] When the current change on the resistance plate 12 exceeds a preset threshold value, the controller controls the electric telescopic rod 9 to be elongated, so as to limit the depression speed and force of the pedal 3.
[0053] In order to improve the reliability of the device, a spring rod 8 is also fixedly connected at the end of the side groove 7 away from the electric telescopic rod 9, and the telescopic end of the spring rod 8 is fixedly connected with the external sleeve 11. In this way, when the electric telescopic rod 9 stops working, the spring rod 8 can provide a reset force to reset the movable shaft 10 and the external sleeve 11.
[0054] The pedal 3 is fixedly provided with a mounting seat 6, and the rotating plate 5 is rotatably connected with the mounting seat 6, so as to realize the relative rotation between the pedal 3 and the rotating plate 5. The pedal 3 is also provided with anti-skid lines, so as to improve the friction force of the driver when stepping on the pedal 3, and prevent slipping.
[0055] The working principle of the first embodiment is as follows: when the driver steps on the pedal 3, the pedal 3 drives the movable shaft 10 to move in the side groove 7 through the rotating plate 5. The moving speed of the movable shaft 10 is converted into current change through the resistance plate 12, and is sensed by the current sensor. When the stepping speed is too fast, the current change on the resistance plate 12 exceeds the preset threshold value, the controller controls the electric telescopic rod 9 to be elongated, and the movement of the movable shaft 10 is limited through the external sleeve 11, so as to limit the depression speed and force of the pedal 3.
[0056] Embodiment Two
[0057] The low-loss electronic throttle limiter provided by the embodiment has a structure similar to that of Embodiment One, but contains some additional optimization features.
[0058] A low-loss electronic throttle limiter includes a base plate 1, a fixed end seat 2 fixedly connected to one end of the top of the base plate 1, a pedal 3 rotatably connected to the top end of the fixed end seat 2, two side seats 4 fixedly connected to the top end of the base plate 1, a rotating plate 5 connected between the two side seats 4 and the pedal 3, and an electronic limiting mechanism arranged between the side seats 4 and the rotating plate 5.
[0059] The electronic limiting mechanism also includes a side slot 7 formed in the adjacent side of the two side seats 4, a movable shaft 10 fixedly connected to both sides of one end of the rotating plate 5 close to the side seat 4, an electric telescopic rod 9 fixedly connected to one end of the side slot 7, an external sleeve 11 rotatably connected to the outside of the movable shaft 10, and the like.
[0060] In addition, the inner side wall of the side slot 7 of the two side seats 4 is provided with a resistance plate 12 for monitoring the movement speed of the movable shaft 10 and converting it into a change in current.
[0061] In order to further optimize the performance of the device, a spring rod 8 is arranged at the end of the side slot 7 away from the electric telescopic rod 9 in this embodiment, which provides a restoring force when the electric telescopic rod 9 stops working.
[0062] The pedal 3 is fixedly provided with a mounting seat 6, which is rotatably connected with the rotating plate 5 to realize the relative rotation between the pedal 3 and the rotating plate 5.
[0063] The electric telescopic rod 9 is connected with a controller, and the resistance plate 12 is connected with a current sensor, and the controller and the current sensor are electrically connected, for controlling the extension length of the electric telescopic rod 9 according to the change in current on the resistance plate 12.
[0064] In addition, the electronic throttle limiter of the embodiment also includes a limit switch (not shown in detail) and an alarm (not shown in detail).
[0065] The limit switch is installed on the inner wall of the side slot 7, and when the movable shaft 10 slides on the resistance plate 12 to a preset position (i.e., the position where the change in current on the resistance plate reaches a preset threshold), the limit switch is triggered to send a signal to the controller to stop the extension of the electric telescopic rod 9.
[0066] The alarm is electrically connected with the controller, and when the controller detects that the pedal 3 is pressed at a speed exceeding a preset threshold, the alarm sends an alarm.
[0067] The working principle of Embodiment Two is as follows:
[0068] The working principle of the second embodiment is similar to that of the above-mentioned first embodiment, and the depressing speed and strength of the pedal 3 are limited by the electronic limiting mechanism.
[0069] When the driver steps on the pedal 3, the pedal 3 drives the movable shaft 10 to move in the side groove 7 through the rotating plate 5, and the moving speed of the movable shaft 10 is converted into current change through the resistance plate 12 and is sensed by the current sensor.
[0070] When the depressing speed is too fast, the controller controls the electric telescopic rod 9 to extend, and the movement of the movable shaft 10 is limited by the external sleeve 11.
[0071] Meanwhile, if the depressing speed of the pedal 3 exceeds the preset threshold value, the limit switch is triggered, the extension and retraction of the electric telescopic rod 9 are stopped, and the alarm gives an alarm to remind the driver to pay attention to driving safety.
[0072] In summary, in the implementation process of the utility model, when the driver steps on the pedal 3, the conventional depressing pressure drives the electric telescopic rod 9 to extend and retract in the conventional state, when the depressing pressure rapidly increases, the pedal 3 rapidly moves downward, and then the rotating plate 5 drives the movable shaft 10 to rapidly move in the side groove 7, the current passing through the resistance plate 12 rapidly changes, the controller controls the electric telescopic rod 9 according to the rapidly changing current on the resistance plate 12, the electric telescopic rod 9 is extended, the movement of the movable shaft 10 is limited, and then the depressing of the pedal 3 is limited.
