Description

Technical Field

[0001] This utility model relates to a self-resetting direction detection mechanism. Background Technology

[0002] Currently, bionic mobile devices on the market, especially electric riding animal toys or amusement facilities, typically use buttons, pedals, or remote controls to achieve basic start / stop and forward / backward control. This control method suffers from a lack of flexibility and a single control method. In actual use, there are often response delays or limited control, making it difficult to achieve natural and smooth directional changes and movement control, and failing to bring a realistic and immersive riding experience.

[0003] For example, CN119097930A discloses a powered wheeled riding device that relies entirely on differentiated force application from both feet to control the toy's movement. This device requires highly skilled operation when traversing terrain with many obstacles, and its emergency response is sluggish. For example, US20180272238A1 discloses an interactive riding toy device. This utility model attempts to simulate the interactive logic of pulling the reins to control the horse's head direction in real riding, but its forward / backward movement requires triggering via a separate button. This "button-triggered" operation lacks both the continuity of riding dynamics and a lack of immersion due to the fragmented operation steps. For example, CN219848117U discloses a biomimetic control riding toy. Although it simulates the control method of riding a horse, the steering smoothness is insufficient, and it cannot achieve turning on the spot or drifting, resulting in insufficient overall controllability and affecting the enjoyment of riding. For example, CN203186508U discloses an electric riding mobile device vehicle with all controls on the steering wheel, and CN221138460U discloses a child electric riding mobile device vehicle. These two control methods require a high degree of hand-eye coordination and cognitive ability. Young users are prone to collision risks due to delayed operation or miscoordination when faced with sudden situations.

[0004] In addition, these products generally use a mechanical steering structure, which has a large turning radius, poor operational flexibility, and is difficult to use in confined spaces. Utility Model Content

The first rotation detection device consists of two sets of rotating rods, each filled into a symmetrical reset hole, which confines the reset rod within the guide groove. The detection shaft of the second rotation detection device is rotatably mounted on its support. The reset rod of the second rotation detection device extends out of the guide groove and is fixedly connected to the support of the first rotation detection device. When the control lever is pushed back and forth, it causes the first rotation detection device to swing back and forth, which in turn causes the reset rod of the second rotation detection device to swing back and forth, thus rotating the detection shaft of the second rotation detection device.

The detection shaft of the second rotation detection device is rotatably mounted on the support base of the second rotation detection device. One end of the detection shaft is fixedly connected to the support base of the first rotation detection device. When the control lever is rotated left or right, it drives the first rotation detection device to rotate as a whole, which in turn drives the detection shaft of the second rotation detection device to rotate.

[0007] Alternatively, the detection mechanism may include two relatively independent first rotation detection devices and a second rotation detection device; each rotation detection device includes a detection shaft, a support base, a reset mechanism, and a sensor, wherein the detection shaft of the first rotation detection device is rotatably mounted on the support base of the first rotation detection device, the support base is provided with a reset mechanism for resetting the detection shaft, the reset mechanism of the first rotation detection device and the reset mechanism of the second rotation detection device include a reset rod and an elastic limiting mechanism, the support base is provided with a guide groove, and reset holes are symmetrically arranged around the guide groove and communicating with the guide groove, one end of the reset rod is fixed to the detection shaft, and the other end passes through the guide groove of the support base, the elastic limiting mechanism has two sets, respectively filled in the symmetrical reset holes, restricting the reset rod in the middle of the guide groove; The reset rod of the first rotation detection device extends out of the guide groove and is fixedly connected to the control lever, so that when the control lever is pushed back and forth, it drives the detection shaft of the first rotation detection device to rotate. The detection shaft of the second rotation detection device is rotatably mounted on the support base of the second rotation detection device, and one end of the detection shaft is fixedly connected to the support base of the first rotation detection device. When the control lever is rotated left and right, it drives the first rotation detection device to rotate as a whole, thereby driving the detection shaft of the second rotation detection device to rotate. The sensor is used to detect the relative movement between the detection shaft of its rotation detection device and the support base and output a signal. The two rotation detection devices are orthogonally connected, and the axes of the detection shafts of the two rotation detection devices are perpendicular to each other. The first rotation detection device is used to detect the signal of forward and backward direction, and the second rotation detection device is used to detect the signal of left and right turning.

[0008] Those skilled in the art will understand that the fixed connection between the first rotation detection device and the control lever also includes a technical solution where the detection shaft or reset rod is extended and the extended portion is directly used as the control lever.

[0009] In theory, the two axes are perpendicular, but due to factors such as machining accuracy and installation method, the axes of the two detection axes may actually deviate to a certain extent. In this case, the purpose of the utility model can still be achieved, but the user experience will be slightly worse.

[0010] Preferably, the detection shaft or reset rod of the second rotation detection device is directly and fixedly connected to the support base of the first rotation detection device; or the detection mechanism further includes a detection device connecting block, one end of which is fixedly connected to the support base of the first rotation detection device, and the other end of which is fixedly connected to one end of the detection shaft or reset rod of the second rotation detection device.

[0011] Preferably, the detection axis of the rotation detection device used to detect left and right turn signals is collinear with the rotation axis of the control lever.

[0012] Preferably, the support base consists of a mechanism connecting block and a mechanism fixing base. The mechanism connecting block and the mechanism fixing base are connected to form a space for the detection shaft to rotate. The guide groove and the reset hole are both set in the mechanism fixing base. One end of the detection device connecting block is connected to the mechanism connecting block or the mechanism fixing base.

[0013] Preferably, each set of elastic limiting mechanisms consists of an outer limiting block, an elastic element, and an inner limiting block that abut against each other in sequence. The elastic limiting mechanisms are respectively installed in symmetrical reset holes, so that the inner limiting block contacts the reset rod, and the two sets of inner limiting blocks restrict the reset rod in the middle of the guide groove, while the outer limiting blocks restrict the elastic limiting mechanism in the reset hole.

[0014] Preferably, the outer limiting block is a set screw, bolt, or plug, which is connected to the reset hole to confine the elastic reset mechanism within the reset hole.

[0015] Preferably, the elastic element is a spring or a sheet spring.

[0016] Preferably, the detection shaft and the support base are rotatably connected by a bearing or by a bushing.

[0017] Preferably, the bearing or bushing is made of metal or plastic.

[0018] Preferably, considering typical design requirements, it is necessary to ensure both the operator's experience and the requirements for ease of operation and safety. Therefore, the rotation range of the detection shaft needs to be controlled. This can be achieved by controlling the size of the guide groove. The reset position, with the reset rod in the middle of the guide groove, is defined as the zero position. When the reset rod rotates to either end of the guide groove, the angle of the detection shaft deviating from the zero position reaches its maximum value. This means the guide groove is designed to accommodate the maximum angle value that the reset rod can cause the detection shaft to deviate from the zero position, with a value ranging from 5º to 60º. In other words, the minimum rotation range of the detection shaft can be controlled within 0±5º, in which case the detection shaft can deviate from the zero position by a maximum of 5º. If the rotation range is too small, the user experience during turning will be poor. The maximum rotation range of the detection shaft can be controlled within 0±60º, in which case the detection shaft can deviate from the zero position by a maximum of 60º. If the rotation range is too large, the operator's body and hand movements will be more pronounced during turning, making it awkward and prone to stalling, also resulting in a poor user experience.

[0019] Preferably, the sensor is a pressure sensor, installed between the elastic element and the inner limiting block, or between the elastic element and the outer limiting block; Alternatively, the sensor may be a Hall sensor, with a magnet fixed to one end of the detection shaft, and the Hall sensor mounted on a support base and cooperating with the magnet. Alternatively, the sensor may be an angle sensor, which is mounted on the detection shaft to measure the rotation angle and direction of the detection shaft; Alternatively, the sensor may be a resistance speed controller, which is mounted on the detection shaft to measure the rotation angle and direction of the detection shaft. Alternatively, the sensor may be a laser rangefinder, which is fixed on a support base, with one end of the reset rod extending out of the guide groove, and the laser rangefinder measuring the displacement of the reset rod. Alternatively, the sensor may be a linear displacement sensor, which is fixed on a support base. One end of the reset rod extends out of the guide groove, and the sensing head of the linear displacement sensor is connected to the end of the reset rod that extends out of the guide groove.

[0020] This utility model also discloses an electric riding mobile device, including a frame, wheels, a control lever, a main control board and a power supply. The wheels include a front wheel and a rear wheel, and also include the aforementioned self-resetting direction detection mechanism. The self-resetting direction detection mechanism is mounted on the frame, with the front and rear wheels mounted at the bottom of the frame. At least two front wheels or two rear wheels are drive wheels, and the drive wheels are distributed on both sides of the frame. For example, two rear wheels are set as drive wheels and distributed on the left and right sides of the frame. The front wheels can be arranged in several or multiple rows, and the number of rear wheels is not limited to two. There can be driven wheels other than drive wheels, or multiple rear wheels as drive wheels. The drive wheels on the same side move in unison. The main control board is used to receive signals from the sensors of the self-resetting direction detection mechanism and control the drive motor according to the signals, while the power supply provides power to the electric riding mobility device.

[0021] Preferably, the top of the control lever of the self-resetting direction detection mechanism is fixed with a handle or steering wheel.

[0022] Preferably, the front wheel is a driven swivel wheel and the rear wheel is a drive wheel; or the rear wheel is a driven swivel wheel and the front wheel is a drive wheel; or all wheels are drive wheels.

[0023] Preferably, it also includes a protective support plate, which is mounted on the frame and located between the rider and the self-resetting direction detection mechanism.

[0024] Preferably, the protective support plate includes a support portion parallel to the control lever and a protective portion arc-shapedly connected to the support portion, the protective portion being located above the handlebars or steering wheel. The protective support plate plays a crucial role in this invention. Because sensors are used to detect movement, the electric riding device of this invention is highly sensitive to handlebar steering; even slight handlebar movement activates the drive motor. Electric riding devices typically adopt an animal-like design, with the direction detection mechanism located at the animal model's head. The protective support plate not only protects the rider from impacting the angular direction detection mechanism but also prevents accidental touches to the handlebars when the rider is leaning over, ensuring the electric riding device only moves when the handlebars are being operated, thus guaranteeing rider safety.

[0025] Preferably, it also includes support legs, through which the front and rear wheels are connected to the frame.

[0026] Preferably, the electric riding device further includes a mechanical braking mechanism that acts on the drive wheel.

[0027] This utility model also discloses a control method for an electric riding mobile device, which relies on the above-mentioned electric riding mobile device. When the control lever is not under force, neither the sensor of the first rotation detection device and the second rotation detection device of the self-resetting direction detection mechanism detects the movement of the control lever. At this time, no signal is generated and the drive wheel does not work. By manipulating the joystick, the direction and speed of the wheels' rotation are controlled according to the joystick's movements. Specifically: Pushing the joystick forward or backward causes the first rotation detection device to swing back and forth, which in turn directly drives or drives the detection shaft of the second rotation detection device to rotate through the reset rod of the second rotation detection device. The sensor of the second rotation detection device detects the rotation direction and angle of the detection shaft and sends a movement signal. After receiving the signal, the main controller controls the drive wheel to rotate forward or backward. Rotating the control lever clockwise or counterclockwise causes the detection shaft of the first rotation detection device to rotate. The sensor of the first rotation detection device detects the rotation direction and angle of the detection shaft and sends a steering signal. After receiving the signal, the main controller controls the speed difference and rotation direction between the drive wheels, thereby causing the electric riding mobile device to turn in the direction of the control lever rotation.

[0028] Alternatively, pushing the joystick forward or backward will directly drive or drive the detection shaft of the first rotation detection device to rotate via the reset rod of the first rotation detection device. The sensor of the first rotation detection device will detect the rotation direction and angle of the detection shaft and send a movement signal. After receiving the signal, the main controller will control the drive wheel to rotate forward or backward. Rotating the control lever clockwise or counterclockwise causes the first rotation detection device to rotate left and right, which in turn causes the detection shaft of the second rotation detection device to rotate. The sensor of the second rotation detection device detects the rotation direction and angle of the detection shaft and sends a steering signal. After receiving the signal, the main controller controls the speed difference and rotation direction between the drive wheels, so that the electric riding mobile device turns in the direction of the control lever rotation.

[0029] The reset mechanism employed in this invention utilizes a reset rod that, due to the rotation of the detection shaft, compresses an elastic limiting mechanism on one side, generating a spring force to drive the detection shaft back to its original position. This resets the detection shaft after the electric riding device completes forward, backward, or turning movements. Because the elastic limiting mechanism has built-in damping buffers, the rotation and reset of the detection shaft are very smooth and without any jerking, resulting in better operability, playability, and user experience. The cooperation between the reset rod and the guide groove enables a limiting function; by controlling the size of the guide groove, the reset rod can only drive the detection shaft to rotate within a certain range, preventing damage to the mechanism from excessive force applied by the operator, especially children. Compared to directly using a torsion spring or leaf spring to reset the detection shaft, extending the reset torque through the reset rod allows for resetting the detection shaft with less force, making it easier and smoother for children to operate.

[0030] This invention's self-resetting direction detection mechanism can accurately capture control actions. It employs a more natural and intuitive control method, making the entire control process more in line with human instincts and easy for beginners to learn. When applied to electrically powered biomimetic mobile devices, such as toy horses or amusement rides, the operator can control all movements and directions of the device through natural intuition, including: forward, backward, left turn, right turn, backward turn, rotation in place, and even drifting. The control is extremely natural, smooth, and fluid, greatly enhancing the driving experience and attracting more visitors. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1 like Figure 1-3 As shown, this rotation detection device includes a detection shaft 1, a support base consisting of a mechanism connecting block 2 and a mechanism fixing seat 3, a reset rod 4, an elastic limiting mechanism consisting of outer limiting blocks 5, 5', elastic elements 6, 6', and inner limiting blocks 7, 7', and also includes a sensor 8. Figure 1-3(not shown in the image) The mechanism connecting block 2 is connected to the mechanism fixing seat 3, forming a space for the detection shaft 1 to rotate. The detection shaft 1 is rotatably installed between the mechanism connecting block 2 and the mechanism fixing seat 3. The mechanism fixing seat 3 is provided with a guide groove and a reset hole symmetrically arranged around the guide groove and communicating with the guide groove. One end of the reset rod 4 is fixed to the detection shaft, and the other end passes through the guide groove of the mechanism fixing seat. There are two sets of outer limiting blocks 5,5', elastic elements 6,6', and inner limiting blocks 7,7'. Each set is sequentially filled into the reset hole, so that the inner limiting blocks 7,7' contact the reset rod 4, and the two sets of inner limiting blocks 7,7' restrict the reset rod 4 to the middle position of the guide groove. The sensor 8 is used to sense changes in the rotation direction and angle of the detection shaft 1.

[0035] The rotation detection device also includes an upper bushing 9 and a lower bushing 10. The detection shaft is provided with an upper bushing fixing position 11 and a lower bushing fixing position 12, and the matching upper bushing 9 and lower bushing 10 are fitted into it. The upper bushing 9 and lower bushing 10 are in contact with the inner side of the mechanism fixing seat 3 and the mechanism connecting block 2.

[0036] Example 2 like Figure 4-5 As shown, the self-resetting direction detection mechanism includes two relatively independent first rotation detection devices 101, second rotation detection devices 102, and detection device connecting block 103; wherein the first rotation detection devices and the second rotation detection devices adopt the rotation detection devices described in Embodiment 1.

[0037] The lower part of the detection shaft of the first rotation detection device is rotatably mounted on the support seat of the first rotation detection device, and the upper part is used to connect the control lever (not shown in the figure). The control lever can be fixedly connected to the detection shaft or integrally formed with the detection shaft. One end of the detection device connecting block is fixedly connected to the support seat of the first rotating detection device; The detection shaft of the second rotation detection device is rotatably mounted on the support base of the second rotation detection device, and one end is fixedly connected to the other end of the detection device connecting block. The sensor 8 is used to detect the relative motion between the detection shaft of the rotation detection device and the support base and output a signal. The sensor 8 outputs a signal through the data output line 12, or it can output a signal through wireless communication. Two rotation detection devices are orthogonally connected, and the axes of their detection shafts are perpendicular to each other. The first rotation detection device is used to detect left and right turning signals, and the second rotation detection device is used to detect forward and backward direction signals.

[0038] The control method of the self-resetting direction detection mechanism based on this embodiment is as follows: when the control lever is not subjected to force, neither of the two rotation detection devices detects the movement of the detection shaft, and no signal is generated at this time; Rotate the control lever clockwise or counterclockwise. As the control lever rotates, it drives the detection shaft, which is fixedly connected to the control lever, to rotate. The sensor located in the first rotation detection device detects the relative movement between the detection shaft and the support base and sends a signal. Pushing the joystick forward or backward causes the joystick to move the connecting block of the detection device via the first rotation detection device. The connecting block then rotates the detection shaft of the second rotation detection device. The sensor located in the second rotation detection device detects the relative movement between the detection shaft and the support base and sends a signal.

[0039] Those skilled in the art will understand that any sensor commonly used in the art that can detect the direction and angle of motion of the detection axis can be used in this invention. Examples are as follows, but not limited to: The sensor is a pressure sensor, installed between the elastic element and the inner limiting block, or between the elastic element and the outer limiting block; Alternatively, the sensor may be a Hall sensor, with a magnet 14 fixed to one end of the detection shaft via a magnet fixing block 13, and the Hall sensor 15 mounted on a support base, cooperating with the magnet, such as... Figure 6 As shown, when the detection shaft 1 rotates, the detection shaft 1 drives the magnet 14 to rotate together through the magnet fixing block 13, so that the magnetic field of the magnet deviates from the perpendicular state of the Hall sensor 15, thereby causing the Hall sensor to generate a signal. Alternatively, the sensor may be an angle sensor 17, which is mounted on the detection shaft to measure the rotation angle and direction of the detection shaft, such as... Figure 7 As shown, when the detection shaft rotates, the angle sensor 16 senses the rotation of the detection shaft, converts the action of the detection shaft into an output signal and outputs it through the signal output line 17, or it can be output wirelessly. Alternatively, the sensor may be a resistance speed controller 18, which is mounted on the detection shaft to measure the rotation angle and direction of the detection shaft. Figure 8-9 As shown, when the detection shaft rotates, the resistance speed controller 18 senses the rotation of the detection shaft, converts the action of the detection shaft into an output signal and outputs it through the signal output line 17, or it can be output wirelessly. Alternatively, the sensor may be a laser rangefinder 19, which is fixed on a support base. One end of the reset rod 4 extends out of the guide groove, and the laser rangefinder measures the displacement of the reset rod. Specifically, for example... Figure 10As shown, the rotation of the detection shaft causes the reset rod 4 to swing, and the position of the reset rod 4 and the laser range sensor 19 changes accordingly, so that the laser range sensor 19 generates a signal and outputs it through the signal output line 17, or it can be output wirelessly. Alternatively, the sensor may be a linear displacement sensor 20, which is fixed on a support base. One end of the reset rod extends out of the guide groove, and the telescopic head of the linear displacement sensor is connected to the end of the reset rod extending out of the guide groove. Figure 11-12 As shown, as 1 rotates, it causes the reset rod 4 to swing, and the reset rod 4 causes the telescopic head of the linear displacement sensor 20 to move, thereby causing the linear displacement sensor 20 to generate a signal. The signal is output by the signal output line 17, or it can be output wirelessly.

[0040] To simplify the structure, save costs, and enable modular production, the detection device connecting block 103 in the self-resetting direction detection mechanism can also be eliminated. Instead, the support base of the first rotation detection device can be directly fixedly connected to the detection shaft of the second rotation detection device. For example, a protrusion can be extended from the support base of the first rotation detection device and connected to the detection shaft of the second rotation detection device.

[0041] When adjusting the positions of the two rotation detection devices, it is preferable to set the detection axis of the rotation detection device used to detect left and right turn signals to be collinear with the rotation axis of the control lever. This setting allows the self-resetting direction detection mechanism to smoothly connect when moving forward, backward, and turning left and right, providing the operator with the best experience.

[0042] Example 3 This self-resetting direction detection mechanism, such as Figure 13As shown, it includes two relatively independent first rotation detection devices 101 and second rotation detection devices 102. Each rotation detection device includes a detection shaft, a support base, a reset mechanism, and a sensor. The lower part of the detection shaft of the first rotation detection device is rotatably mounted on the support base, and the upper part is used to connect to the control lever 700, so that the control lever rotates left and right, driving the detection shaft of the first rotation detection device to rotate. The support base is provided with a reset mechanism to reset the detection shaft. The reset mechanisms of the first and second rotation detection devices include a reset rod and an elastic limiting mechanism. The support base is provided with a guide groove and reset holes symmetrically arranged around the guide groove and communicating with the guide groove. One end of the reset rod is fixed to the detection shaft, and the other end passes through the guide groove of the support base. The elastic limiting mechanism has... Two sets are respectively installed in symmetrical reset holes, confining the reset rod in the middle of the guide groove; the detection shaft 1 of the second rotation detection device is rotatably mounted on the support seat of the second rotation detection device, and the reset rod 4 of the second rotation detection device extends out of the guide groove and is fixedly connected to the support seat of the first rotation detection device. When the control lever is pushed back and forth, it drives the first rotation detection device to swing back and forth as a whole, which in turn drives the reset rod of the second rotation detection device to swing back and forth, causing the detection shaft of the second rotation detection device to rotate; the sensor is used to detect the relative movement between the detection shaft of the rotation detection device it is located in and the support seat and output a signal; the two rotation detection devices are orthogonally connected, and the axes of the detection shafts of the two rotation detection devices are perpendicular to each other; the first rotation detection device is used to detect the left and right turning signals, and the second rotation detection device is used to detect the forward and backward direction signals; The control method of the self-resetting direction detection mechanism based on this embodiment is as follows: when the control lever is not under force, neither of the two rotation detection devices detects the movement of the detection shaft, and no signal is generated at this time; Rotate the control lever clockwise or counterclockwise. As the control lever rotates, it drives the detection shaft, which is fixedly connected to the control lever, to rotate. The sensor located in the first rotation detection device detects the relative movement between the detection shaft and the support base and sends a signal. Pushing the joystick forward or backward causes the joystick to swing via the first rotation detection device, which in turn causes the reset rod of the second rotation detection device to rotate.

One end of the detection shaft 1 is fixedly connected to a control lever 700, so that the detection shaft of the first rotation detection device rotates when the control lever is pushed back and forth. The support base is provided with a reset mechanism for resetting the detection shaft. The reset mechanisms of the first and second rotation detection devices include a reset rod and an elastic limiting mechanism.

As the joystick rotates, the first rotation detection device drives the detection shaft of the second rotation detection device to rotate.

The reset mechanisms of the first and second rotation detection devices include a reset rod and an elastic limiting mechanism. The support base has a guide groove and reset holes symmetrically arranged around the guide groove and communicating with it. One end of the reset rod is fixed to the detection shaft, and the other end passes through the guide groove of the support base. There are two sets of elastic limiting mechanisms, which are respectively filled in the symmetrical reset holes to restrict the reset rod in the middle of the guide groove. The reset rod of the first rotation detection device 101 extends out of the guide groove. The control lever 700 is fixedly connected to or integrally formed with the control lever, so that when the control lever is pushed back and forth, it drives the detection shaft 1 of the first rotation detection device to rotate; the detection shaft 1 of the second rotation detection device 102 is rotatably mounted on the support of the second rotation detection device, one end of the detection shaft 1 is fixedly connected to the support of the first rotation detection device, and the detection shaft is coaxial with the rotation axis of the control lever. When the control lever rotates left and right, it drives the first rotation detection device to rotate as a whole, and then drives the detection shaft of the second rotation detection device to rotate; the sensor is used to detect the relative movement between the detection shaft of the rotation detection device it is located on and the support and outputs a signal; the two rotation detection devices are orthogonally connected, and the axes of the detection shafts of the two rotation detection devices are perpendicular to each other; the first rotation detection device is used to detect the signal of forward and backward direction, and the second rotation detection device is used to detect the signal of left and right turn.

[0048] The control method of the self-resetting direction detection mechanism based on this embodiment is as follows: when the control lever is not subjected to force, neither of the two rotation detection devices detects the movement of the detection shaft, and no signal is generated at this time; Pushing the joystick forward or backward moves the reset lever of the first rotation detection device, which in turn moves the detection shaft of the first rotation detection device.

As the joystick rotates, the first rotation detection device drives the detection shaft of the second rotation detection device to rotate.

The front wheels or the rear wheels are drive wheels, and the other wheels are driven wheels. Alternatively, both the front wheels and the rear wheels can be set as drive wheels. The main controller 500 receives signals from the two sensors of the self-resetting direction detection mechanism 100 and controls the rotation direction and speed of the drive wheels according to the signals, thereby controlling the movement state and direction of the toy. The battery is used to power the system.

[0051] The electric riding mobility device also includes a control lever 700, which is installed on the upper part of the self-resetting direction detection mechanism, and a handle 1000 or a steering wheel is fixed to the top of the control lever.

[0052] The electric riding device also includes a protective support plate 800, which is mounted on the frame and located between the rider and the self-resetting direction detection mechanism. The protective support plate includes a support part parallel to the control lever and a protective part arc-shapedly connected to the support part. The protective part is located above the handlebar or steering wheel, thereby preventing the rider from touching the control lever or misoperating the electric riding device when leaning over its head, causing the electric riding device to move.

[0053] The electric riding mobility device also includes foot pedals 900, which are located on the left and right front legs, near the front wheel.

The mechanical braking mechanism can adopt a braking system commonly known in the art, such as a mechanical (cable-operated) disc brake, a mechanical (cable-operated) drum brake, a hydraulic disc brake, or a hydraulic drum brake.

[0055] The following control logic can be used: The user holds the handle and pushes it forward to move the electric riding device forward; pulls the handle back to move the electric riding device backward; turns the handle to the left to turn the electric riding device left; turns the handle to the right to turn the electric riding device right; pulls the handle back or pushes it forward in the opposite direction of the electric riding device's movement to brake the toy; by pushing forward (when moving forward) and turning the handle left and right, the toy can turn left and right when moving forward; by pulling back (when moving backward) and turning the handle left and right, the toy can turn left and right when moving backward.
