Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, specifically relating to a control handle device and an electric four-wheeled vehicle using the device. Background Technology

[0002] An electric four-wheeled vehicle is a low-speed personal transportation tool equipped with an electric drive system. It typically consists of four parts: a chassis, a seat on the chassis, a drive motor, a controller, and a battery. Unlike traditional electric tricycles, electric vehicles, and bicycles, electric four-wheeled vehicles usually have an intelligent control system, allowing for convenient control of various functions such as forward and backward movement, steering, and seat folding.

[0003] Currently, existing electric four-wheeled vehicles are typically used as electric wheelchairs, serving as low-speed mobility tools for the elderly who are frail or have limited mobility. The controller for these vehicles is usually located at the front of the armrest, and movement and steering are controlled by cranking a joystick with one hand. This traditional joystick-style controller is relatively simple in function, offers limited control, and lacks sufficient operability and human-computer interaction, failing to meet more user needs. For example, for young people, electric four-wheeled vehicles can serve as low-speed mobility tools for outdoor activities, such as in tourist areas, parks, or golf courses. The aforementioned traditional joystick-style control method is not suitable for young people (the joystick-style control is used because the elderly or disabled have limited upper body mobility and need to lean against the backrest for extended periods, hence the joystick-style controller at the front of the armrest).

[0004] Therefore, this utility model designs a control handle device and an electric four-wheeled vehicle using the device. The control handle device is set at the front of the electric four-wheeled vehicle, which is more suitable for the operation of young people and can be used as a low-speed transportation tool for outdoor activities. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art by providing a control handle device and an electric four-wheeled vehicle using the device.

[0006] This utility model is achieved through the following technical solution:

The display is connected and installed at the front end of the two U-shaped tubes, and the controller is connected and installed at the rear end of the two U-shaped tubes. A digital gyroscope and an accelerometer are installed inside the controller, and control buttons and a speed adjustment lever are also provided on the controller.

[0008] In the above technical solution, the controller includes a control panel and a control device mounting box. The control panel is mounted on the upper layer of the control device mounting box and has multiple control buttons.

[0009] In the above technical solution, the control buttons include: speed gear control button, volume control button, light control button, horn control button, forward gear control button, and reverse gear control button.

[0010] In the above technical solution, the control device mounting box is a box with an open bottom. A mounting plate is fixedly connected inside the control device mounting box by bolts. The speed control lever is rotatably mounted on the mounting plate via a rotating shaft. The speed control lever is used to control the vehicle speed. A mounting cylinder is also provided on the mounting plate. The tail end of the grip is fixedly connected to the wall of the mounting cylinder. The mounting cylinder is rotatably mounted on the mounting bracket on the top of the head tube via a rotating component provided inside the cylinder, thereby enabling the entire controller, grip, and display to rotate on the head tube.

[0011] In the above technical solution, a circuit board is also provided inside the control device mounting box, and the digital gyroscope and accelerometer are mounted on the circuit board.

[0012] An electric four-wheeled vehicle includes a chassis, on which a seat structure and the aforementioned control handle device are mounted.

[0013] In the above technical solution, the seat structure includes a seat support, a seat, a backrest frame, and armrests. The seat is mounted on the vehicle chassis via the seat support, the backrest frame is mounted on the seat support or on the seat, and the armrests are mounted on the backrest frame.

[0014] In the above technical solution, a head tube is provided at the front of the vehicle chassis, and the control handle device is rotatably mounted on the top of the head tube.

[0015] In the above technical solution, the head tube is designed to be height-adjustable, thereby allowing adjustment of the appropriate height position of the handlebar device.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] This utility model features a meticulously designed control handle, consisting of a grip and a controller and display mounted on it. The controller incorporates a digital gyroscope and accelerometer. When the user grips the grip and rotates the entire handle-type control device on the head tube, the digital gyroscope and accelerometer also rotate, detecting the attitude information of the control handle during steering. The main controller then uses this attitude information to control the wheel motors to perform corresponding steering actions, thus achieving vehicle steering. Furthermore, the controller includes necessary control buttons and a speed adjustment lever for controlling the electric four-wheeled vehicle. This handle-type control device significantly enhances the maneuverability, fun, and human-computer interaction of the electric four-wheeled vehicle, making it suitable for young people and ideal for use as a low-speed transportation tool for outdoor activities.

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0024] See appendix Figure 1 An electric four-wheeled vehicle includes a chassis 1, on which a seat structure 2 and a control handle device 4 are provided.

[0025] The chassis 1 has four wheels, including two front wheels and two rear wheels. The wheels are connected to a motor, which controls the rotation of the wheels.

[0026] The seat structure 2 includes a seat support 21, a seat 22, a backrest frame 23, and an armrest 24. The seat 22 is mounted on the vehicle chassis 1 via the seat support 21, the backrest frame 23 is mounted on the seat support 21 or on the seat 22, and the armrest 24 is mounted on the backrest frame 23.

[0027] A head tube 3 is provided at the front of the chassis 1. The control handle 4 is rotatably mounted on the top of the head tube 3, and the electric four-wheeled vehicle can be operated through the control handle 4. The control handle 4 includes a grip 41 and a controller 42 and a display 43 mounted on the grip 41. The controller 42 has a built-in digital gyroscope and accelerometer. When the user holds the grip 41 and controls the control handle 4 to rotate on the head tube 3, the digital gyroscope and accelerometer also rotate accordingly, thereby detecting the attitude information of the control handle 4 during the steering process through the digital gyroscope and accelerometer. The digital gyroscope and accelerometer are electrically connected to the main controller of the electric four-wheeled vehicle (the main controller is generally installed on the chassis of the electric four-wheeled vehicle). The main controller calculates the attitude information of the handlebar device 4 in real time based on the detection data of the digital gyroscope and accelerometer (during the calculation, data fusion algorithms such as complementary filtering or Kalman filtering are required; these are existing conventional algorithms and will not be elaborated here). Based on the attitude information of the handlebar device 4, the main controller controls the wheel motors to perform corresponding steering actions, thereby realizing the steering of the vehicle. In addition, the controller 42 is also equipped with necessary control buttons and speed adjustment levers to realize the control of the electric four-wheeled vehicle. See the appendix below. Figure 2 - Appendix Figure 4 This paper will specifically introduce the structure and function of the control handle device 4 described in this utility model.

[0028] As described above, the control handlebar device 4 includes a grip 41, a controller 42, and a display 43. Specifically, the grip 41 uses two U-shaped tubes arranged symmetrically on the left and right sides. The display 43 is connected and installed at the front end of these two U-shaped tubes, and the controller 42 is connected and installed at the rear end of these two U-shaped tubes. The controller 42 includes a control panel 421, a speed control lever 422, and a control device mounting box 423. The control panel 421 is installed on the upper layer of the control device mounting box 423. The control panel 421 is provided with multiple control buttons. Preferably, the control buttons include: a first speed gear control button 01 marked "Fast" (preferably, the speed in this first speed gear is 10-12 kilometers per hour, equivalent to the speed of a low-speed bicycle), and a second speed gear control button 02 marked "Slow" (preferably, the speed in this second speed gear is 3-5 kilometers per hour). The control unit 423 is preferably an open-bottom box. A mounting plate 4231 is bolted inside the control unit 423. The speed control lever 422 is rotatably mounted on the mounting plate 4231 via a rotating shaft and is used to control vehicle speed.

[0031] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0032] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0033] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
