Description

Technical Field

[0001] This utility model relates to a pressure-controlled direction detection mechanism and an electric riding mobility device. 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 toy car with all controls on the steering wheel, and CN221138460U discloses a children's electric toy car. These two control methods require a high level of hand-eye coordination and cognitive ability. Young users may easily cause collision risks due to delayed operation or miscoordination in the face of 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

[0005] This utility model discloses a pressure-controlled direction detection mechanism, which can be used to detect forward and backward pushing and pulling, left and right turning operations.

[0006] The objective of this utility model is achieved through the following technical solution: A pressure-controlled direction detection mechanism includes a front and rear push-pull steering rod, a fixing block, and a mounting base. The bottom of the front and rear push-pull steering rod is provided with a fixedly connected left and right steering rod. The left and right steering rods are axially perpendicular to the front and rear push-pull steering rod. The connection between the front and rear push-pull steering rod and the left and right steering rod is located inside the fixing block. The front and rear push-pull steering rod can swing back and forth in a straight line or rotate around its own axis. When the front and rear push-pull steering rod rotates around its own axis, it will drive the left and right steering rod to swing back and forth. The mounting base consists of a base plate and side plates perpendicular to both sides of the base plate. The fixing block is fixed to the base plate and placed between the side plates. It also includes front and rear pressure sensors and left and right pressure sensors, all of which are fixed to the side plate. The front and rear push-pull steering rods abut against the front and rear pressure sensors, and the left and right steering rods abut against the left and right pressure sensors.

[0007] Preferably, there are two front and rear pressure sensors, which are fixed on the two side plates at the positions corresponding to the front and rear push-pull steering rods. When the front and rear push-pull steering rods are pushed forward, one of the pressure sensors is activated, and when the front and rear push-pull steering rods are pulled backward, the other pressure sensor is activated.

[0008] Preferably, there are two left and right pressure sensors, which are fixed on the two side plates at the positions corresponding to the left and right steering rods. When the steering rods are pushed or pulled to the left, the left and right steering rods swing backward, directly or through the spring to touch one of the pressure sensors. When the steering rods are pushed or pulled to the right, the left and right steering rods swing forward, directly or through the spring to touch the other pressure sensor.

[0009] Preferably, there is one front and rear pressure sensor, fixed on one side plate at the position corresponding to the front and rear push-pull steering rods. A first spring block is provided on the other side plate at the position corresponding to the front and rear push-pull steering rods. In the initial state, the front and rear push-pull steering rods are not subjected to any external control force, and the front and rear pressure sensors are subjected to the pre-pressure applied by the first spring block through the front and rear push-pull steering rods. When the front and rear push-pull steering rods are pushed forward, the first spring block is further compressed and stores force, and the pressure on the front and rear pressure sensors decreases. When the external control force disappears, the first spring block releases the stored force, and the front and rear push-pull steering rods and the front and rear pressure sensors return to the initial state. When the front and rear push-pull steering rods are pushed backward, the pressure on the front and rear pressure sensors further increases. When the external control force disappears, under the restoring action of the first spring block, the front and rear push-pull steering rods and the front and rear pressure sensors return to the initial state.

[0010] Preferably, it also includes a first adjusting bolt, which is movably connected to the side plate on the mounting base and abuts against one end of the first spring block, for adjusting the pre-pressure received by the front and rear pressure sensors in the initial state.

[0011] Preferably, there is one left and right pressure sensor, fixed on one side plate at the position corresponding to the left and right push-pull steering rods. A second spring block is provided on the other side plate at the position corresponding to the left and right push-pull steering rods. In the initial state, the left and right push-pull steering rods are not subjected to any external control force, and the left and right pressure sensors are subjected to the pre-pressure applied by the second spring block through the left and right push-pull steering rods. When the push-pull steering rod is turned to the right, the push-pull steering rods drive the left and right push-pull steering rods to swing forward, and the second spring block is further compressed and stores force, reducing the pressure on the left and right pressure sensors. When the external control force disappears, the second spring block releases the stored force, and the left and right push-pull steering rods and left and right pressure sensors return to the initial state. When the push-pull steering rod is turned to the left, the push-pull steering rods drive the left and right push-pull steering rods to swing backward, and the pressure on the left and right pressure sensors further increases. When the external control force disappears, under the restoring action of the second spring block, the left and right push-pull steering rods and left and right pressure sensors return to the initial state.

[0012] Preferably, it also includes a second adjusting bolt, which is movably connected to the side plate on the mounting base and abuts against one end of the second spring block, for adjusting the pre-pressure received by the left and right pressure sensors in the initial state.

[0013] Preferably, the fixing block consists of an upper fixing block and a lower fixing block, and the front and rear push-pull steering rods and the left and right steering rods are fixedly connected by ball seats, with the ball seats fixed between the upper fixing block and the lower fixing block; or the fixing block consists of a left fixing block and a right fixing block, with the ball seats fixed between the left fixing block and the right fixing block.

[0014] This utility model also discloses an electric riding mobile device, including a frame, wheels, a main control board and a power supply, wherein the wheels include a front wheel and a rear wheel, and also includes the aforementioned pressure-controlled direction detection mechanism; The pressure-controlled direction detection mechanism is fixed to the frame by a mounting base. The front and rear wheels are installed 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. There can be several or multiple rows of front wheels. The number of rear wheels is not limited to two. There can be driven wheels other than drive wheels. There can also be multiple rear wheels as drive wheels. The drive wheels on the same side move in the same direction. The main control board is used to receive signals from the sensors of the pressure-controlled direction detection mechanism and control the drive motor and power supply to the electric riding mobility device according to the signals.

[0015] Preferably, the top of the front and rear push-pull steering rods of the pressure-controlled steering detection mechanism is fixed with a handle or steering wheel.

[0016] 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.

[0017] Preferably, it also includes a protective support plate, which is mounted on the frame and located between the rider and the pressure-controlled direction detection mechanism.

[0018] Preferably, the protective support plate includes a support portion that is substantially parallel to the front and rear push-pull steering rods and a protective portion that is arc-shapedly connected to the support portion, the protective portion being located above the handle or steering wheel.

[0019] Preferably, it also includes support legs, through which the front and rear wheels are connected to the frame.

[0020] Preferably, the electric riding device further includes a mechanical braking mechanism that acts on the drive wheel.

[0021] 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 front and rear push-pull steering rods are not under force, the front and rear pressure sensors and left and right pressure sensors of the pressure control type direction detection mechanism do not detect the movement of the front and rear push-pull steering rods. At this time, no signal is generated and the drive motor does not work. By manipulating the front and rear steering levers, the direction and speed of wheel rotation are controlled according to the actions of the steering levers. Specifically: Pushing the steering lever forward or backward applies pressure to the front and rear pressure sensors. The front and rear pressure sensors detect the direction of movement of the steering lever and send a movement signal. After receiving the signal, the main controller controls the drive wheels to rotate forward or backward. Rotating the steering lever clockwise or counterclockwise causes the left and right steering levers to rotate to the right or left. The left and right pressure sensors detect the rotation direction of the left and right steering levers and send 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 device turns in the direction of the steering lever rotation.

[0022] This utility model's pressure-controlled direction detection mechanism, through the cooperation of forward / backward push-pull steering rods and left / right steering rods with pressure sensors, can accurately capture handle movements. When applied to electrically powered biomimetic mobile devices such as toy horses or amusement rides, the operator can intuitively control all movements and directions of the device, including forward, backward, left turn, right turn, reverse turn, stationary rotation, and even drifting. The control is extremely natural, smooth, and fluid, greatly enhancing the driving pleasure. This utility model adopts a control method that is more in line with natural intuition, making the entire operation more in line with human instinct. Attached Figure Description

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1 like Figure 1-2 As shown, this pressure-controlled direction detection mechanism includes a front and rear push-pull steering rod 1, a fixing block, and a mounting base 8. The fixing block consists of an upper fixing block 4 and a lower fixing block 5. The bottom of the front and rear push-pull steering rod 1 is provided with a fixedly connected left and right steering rod 9. The left and right steering rod 9 is axially perpendicular to the front and rear push-pull steering rod. The connection between the front and rear push-pull steering rod and the left and right steering rod is located between the upper fixing block 4 and the lower fixing block 5. The front and rear push-pull steering rod 1 can swing back and forth in a straight line or rotate around its own axis. When the front and rear push-pull steering rod 1 rotates around its own axis, it will drive the left and right steering rod 9 to swing back and forth. Generally speaking, the front and rear push-pull steering rod and the left and right steering rod can be connected by a ball seat. The mounting base 8 consists of a base plate and two side plates perpendicular to the base plate. The fixing block is fixed to the base plate and placed between the side plates. It also includes front and rear pressure sensors and left and right pressure sensors. There are two front and rear pressure sensors 2 and 3, which are fixed on the two side plates at the positions corresponding to the front and rear push-pull steering rods. The front and rear push-pull steering rods abut against the two front and rear pressure sensors respectively. When the front and rear push-pull steering rods are pushed forward, one of the pressure sensors 2 is triggered. When the front and rear push-pull steering rods are pulled backward, the other pressure sensor 3 is triggered. There are two left and right pressure sensors 6 and 7, which are fixed on the two side plates at the positions corresponding to the left and right steering rods. The left and right steering rods abut against the two left and right pressure sensors respectively. When the left and right steering rods are turned to the left, one of the pressure sensors 7 is triggered, and when the left and right steering rods are turned to the right, the other pressure sensor 6 is triggered.

[0026] like Figure 3 As shown, a spring 10 can also be installed between the front / rear push-pull steering rod or the left / right steering rod and the pressure sensor. The front / rear push-pull steering rod or the left / right steering rod contacts the pressure sensor through the spring, thereby increasing the range of motion of the front / rear push-pull steering rod or the left / right steering rod and enhancing the driving experience.

[0027] Example 2 like Figure 4-5 As shown, this pressure-controlled direction detection mechanism includes a front and rear push-pull steering rod 1, a fixing block, and a mounting base 8. The fixing block consists of an upper fixing block 4 and a lower fixing block 5. The bottom of the front and rear push-pull steering rod 1 is provided with a fixedly connected left and right steering rod 9. The left and right steering rod 9 is axially perpendicular to the front and rear push-pull steering rod. The connection between the front and rear push-pull steering rod and the left and right steering rod is located between the upper fixing block 4 and the lower fixing block 5. Generally speaking, the front and rear push-pull steering rod and the left and right steering rod can be connected by a ball seat. The mounting base 8 consists of a base plate and two side plates perpendicular to the base plate. The fixing block is fixed to the base plate and placed between the side plates. It also includes front and rear pressure sensors and left and right pressure sensors. There is one front and rear pressure sensor 2, which is fixed on one side plate at the position corresponding to the front and rear push-pull steering rod 1. A first spring block 10 is provided on the other side plate at the position corresponding to the front and rear push-pull steering rod 1. There is one left and right pressure sensor 6, which is fixed on one side plate at the position corresponding to the left and right steering rod 9. A second spring block 11 is provided on the other side plate at the position corresponding to the left and right steering rod 9. In the initial state, the front and rear push-pull steering levers 1 are not subjected to any external control force. The front and rear pressure sensors 2 are subjected to the preload applied by the first spring block 10 through the front and rear push-pull steering levers 1. When the front and rear push-pull steering levers 1 are pushed forward, the first spring block 10 is further compressed and stores force, and the pressure on the front and rear pressure sensors 2 decreases. When the external control force disappears, the first spring block 10 releases the stored force, and the front and rear push-pull steering levers 1 and the front and rear pressure sensors 2 return to their initial state. When the front and rear push-pull steering levers 1 are pushed backward, the pressure on the front and rear pressure sensors 2 increases further. When the external control force disappears, under the restoring action of the first spring block 10, the front and rear push-pull steering levers 1 and the front and rear pressure sensors 2 return to their initial state. During this operation, the forward and backward movement of the front and rear push-pull steering levers 1 can be determined by detecting the pressure change on the pressure sensors 2. Similarly, when the front and rear push-pull steering levers 1 are rotated left and right, the left and right steering levers 9 will swing back and forth, further applying or releasing pressure to the left and right pressure sensors 6. The left and right steering movement of the front and rear push-pull steering levers 1 can be determined by detecting the pressure change on the pressure sensors 6.

[0028] It also includes a first adjusting bolt 3 and a second adjusting bolt 7. The first adjusting bolt 3 is connected to the side plate on the mounting base 8 and abuts against one end of the first spring block 10, and is used to adjust the pre-pressure received by the front and rear pressure sensors 2 in the initial state. The second adjusting bolt 7 is connected to the side plate on the mounting base 8 and abuts against one end of the second spring block 11, and is used to adjust the pre-pressure received by the pressure sensor 6 in the initial state. Those skilled in the art should understand that the fixing block is divided into an upper fixing block 4 and a lower fixing block 5 for ease of installation. The same applies to dividing the fixing block into a left fixing block and a right fixing block. No further drawings will be provided.

[0029] Alternatively, a spring can be installed between the front / rear push-pull steering rod or the left / right steering rod and the pressure sensor. The front / rear push-pull steering rod or the left / right steering rod contacts the pressure sensor through the spring, thereby allowing the front / rear push-pull steering rod or the left / right steering rod to have a larger range of motion.

[0030] Those skilled in the art should understand that combinations of the solutions in Embodiment 1 and Embodiment 2 are also within the protection scope of this utility model. For example, a pressure-controlled direction detection mechanism can be configured to have two front and rear pressure sensors and one left and right pressure sensor; or it can have one front and rear pressure sensor and two left and right pressure sensors.

[0031] Example 3 like Figure 6-7 As shown, the electric riding mobile device using the pressure-controlled direction detection mechanism includes a pressure-controlled direction detection mechanism 100, a frame 200, two front wheels 300, two rear wheels 400, a main controller 500, and a battery 600. The mounting base of the pressure-controlled direction detection mechanism 100 is fixed to the frame 200. The frame 200 has two front legs and two rear legs, which are respectively connected to the front wheels 300 and the rear wheels 400. The front wheels are either drive wheels or the rear wheels are drive wheels, and the other wheels are omnidirectional driven wheels. The main controller 500 receives signals from the sensors of the pressure-controlled 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 electric riding mobile device. The battery 600 is used to power the device.

[0032] Alternatively, you can choose to have all four wheels as drive wheels.

[0033] The electric riding device also includes a protective support plate 700, 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.

[0034] The electric riding mobility device also includes pedals 800, which are located on the left and right front legs, near the front wheel.

[0035] It also includes a handle 900, which is fixedly connected to the upper end of the front and rear push-pull steering rod 1 of the pressure-controlled direction detection mechanism.

[0036] 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.
