Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

In the description of this utility model, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0039] The specific application scenario of this application is as follows: When a user is pushing an electric mobility scooter, the controller can control the power module to provide output power, thereby reducing the physical effort required by the user to push the vehicle. In particular, when going uphill or on uneven roads, the user needs to exert considerable effort to push the scooter; by providing pushing assistance, the user can easily push the scooter uphill or over uneven roads. The power module is used to provide power to the electric mobility scooter.

[0040] In existing technologies, when controlling the power module to provide output power, the power module usually provides a fixed output power, which is not very flexible for users and makes it impossible to adjust the output power according to the actual scenario.

[0041] The propulsion assist system and electric mobility scooter provided in this application are intended to solve the above-mentioned technical problems of the prior art.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Figure 1 A schematic diagram of a promotion assistance system provided in this application is shown below. Figure 1 As shown, the pushing assistance system is installed on the electric mobility scooter. The pushing assistance system includes a wheel speed sensor 101 and a controller 102. The wheel speed sensor 101 is connected to the controller 102, and the controller 102 is connected to the power module 103.

[0044] The wheel speed sensor 101 is used to acquire the pushing speed signal and send the pushing speed signal to the controller 102;

[0045] The controller 102 is used to control the output power applied to the power module 103 according to the pushing speed signal when providing pushing assistance, so that the power module 103 provides output power.

[0046] To adjust the output power provided by the power module 103, it can be adjusted according to the pushing speed of the electric mobility scooter. Optionally, when the pushing speed is high, a higher output power is provided to maintain the higher pushing speed; when the pushing speed is low, a lower output power is provided to maintain the lower pushing speed.

[0047] For example, when the pushing speed is stable at 3km / h, the corresponding output power is 1; when the pushing speed is stable at 2km / h, the corresponding output power is 2. The output power 1 is greater than the output power 2, which allows the vehicle to maintain the current pushing speed, improves the user's pushing experience, and enables flexible control of the vehicle.

[0048] Optionally, the pushing speed can be obtained based on wheel speed sensors 101, which can be mounted on the wheel hub. Optionally, there can be two or more wheel speed sensors 101, each mounted on a different wheel hub, to determine the pushing speed based on the values ​​from multiple wheel speed sensors 101. For example, the average pushing speed detected by multiple wheel speed sensors 101 can be determined as the pushing speed.

[0049] Optionally, the controller 102 can be implemented using hardware circuitry. Multiple switches can be configured, and different switches can be triggered based on the acquired propulsion speed signal. Each switch corresponds to a different output power. When the power module 103 provides the output power based on a determined output power, this can be achieved through PID (Proportional Integral Derivative) control. Optionally, PID control is proportional, integral, and derivative control. Components such as resistors, capacitors, and operational amplifiers can be used to form a proportional (P) control unit, an integral (I) control unit, and a derivative (D) control unit, thereby achieving control of the output power.

[0050] Optionally, the power module 103 can be a motor. The controller 102 can be an MCU (Microcontroller Unit) or a motor controller, and the controller 102 can control the motor.

[0051] This invention provides a pushing assistance system installed on an electric mobility scooter. The system includes a wheel speed sensor and a controller. The wheel speed sensor is connected to the controller, which is connected to a power module. The wheel speed sensor acquires a pushing speed signal and sends it to the controller. The controller, when providing pushing assistance, controls the output power applied to the power module based on the pushing speed signal, enabling the power module to provide output power to the electric mobility scooter. This allows for flexible control of the output power provided by the power module, avoiding the provision of the same output power in different scenarios and improving the user's pushing experience under various road conditions.

[0052] Figure 2 A schematic diagram of another implementation assistance system provided in this application is shown below. Figure 2 The following section explains the other structures included in the implementation support system.

[0053] Optionally, the system further includes: a gyroscope sensor 104; the gyroscope sensor 104 is connected to the controller 102;

[0054] The gyroscope sensor 104 is used to acquire the slope signal and send the slope signal to the controller 102;

[0055] The controller 102 is also used to control the output power applied to the power module 103 according to the slope signal when providing pushing assistance, so that the power module 103 provides output power.

[0056] A gyroscope sensor 104 can also be installed on the electric mobility scooter. The gyroscope sensor 104 can measure the vehicle's attitude. Specifically, it can be a slope signal, which can be sent to the controller 102. The controller 102 can control the output power based on the slope signal.

[0057] Understandably, when pushing the vehicle on a flat surface, the user expends less physical effort; conversely, when pushing the vehicle uphill, the user expends more physical effort. Therefore, the output power can be adjusted according to the slope signal, allowing the user to push the vehicle on both flat and sloped surfaces with the same amount of physical effort, without needing to adjust the pushing force, thus improving the user experience.

[0058] When the slope signal is large, it indicates that the uphill slope is steep, and the output power that can be applied to the power module 103 is large; when the slope signal is small, it indicates that the uphill slope is gentle, and the output power that can be applied to the power module 103 is small.

[0059] By setting a gyroscope sensor 104 to obtain the slope signal, the output power is controlled based on the slope signal. The output power is adjusted according to different road conditions, so that the user can push the vehicle forward without changing the pushing method under different road conditions.

[0060] Optionally, the system further includes: a trolley force sensor 105; the trolley force sensor 105 is connected to the controller 102;

[0061] The pushcart force sensor 105 is used to acquire the force signal applied by the user to the electric mobility scooter and send the force signal to the controller 102;

[0062] The controller 102 is also used to control the output power applied to the power module 103 according to the force signal when providing pushing assistance, so that the power module 103 provides output power.

[0063] Optionally, a push-cart force sensor 105 can be installed on the electric mobility scooter to determine the user's intention based on the force signal detected by the push-cart force sensor 105, thereby adjusting the output power according to the user's intention. The push-cart force sensor 105 can determine the force signal applied by the user to the electric mobility scooter; different force signals can reflect different user intentions, such as acceleration or deceleration. After acquiring the force signal, the push-cart force sensor 105 can send the force signal to the controller 102.

[0064] The controller 102 is connected to the power module 103. The controller 102 can control the output power based on the received force signal, thereby controlling the power module 103 to provide the output power.

[0065] For example, the force applied by the user when the road surface is rough is different from the force applied when the road surface is flat. Therefore, based on the force signal when the road surface is rough, the output power applied to the power module 103 can be increased so that the force expended by the user when pushing the vehicle through rough sections is not much different from that on flat roads, and the vehicle can be pushed through rough sections without much effort.

[0066] By setting a force sensor 105 to detect the force signal, the output power can be controlled. The output power can be flexibly adjusted according to changes in road conditions, adapting to different road conditions and fully meeting the specific needs of users in different scenarios.

[0067] Optionally, when the electric mobility scooter is heavy, the controller 102 adjusts the output power based on the pushing force sensor 105, resulting in a better user experience. This is because when the vehicle is heavy, the user cannot push it to a certain speed. If the pushing force sensor 105 senses that the user is applying a certain forward pushing force, the output power can be increased, so that the user does not have to push the vehicle to a certain speed to maintain that speed.

[0068] By setting a pushcart force sensor 105 to obtain force signals, the output power is controlled based on the force signals. The output power is adjusted according to the user's intention, making the vehicle more responsive and requiring less effort to push.

[0069] In one embodiment, the controller 102 is specifically configured to reduce the output power applied to the power module 103 according to the backward pulling force signal; and / or, the controller 102 is specifically configured to increase the output power applied to the power module 103 according to the forward thrust signal.

[0070] When the force signal is a backward pulling force signal, the output power can be reduced according to the specific pulling force value. Optionally, when it is a pulling force signal, the output power is reduced. The amount of reduction in output power is related to the backward pulling force value. The larger the backward pulling force value, the larger the reduction in output power; the smaller the backward pulling force value, the smaller the reduction in output power.

[0071] Optionally, the controller 102 can select the corresponding switch for the range to which the backward pulling force value belongs, and turn on the switch of the range corresponding to the backward pulling force value to obtain the amount of output power reduction, thereby determining the output power.

[0072] The reason for reducing output power based on the backward pulling force signal is that when a user is pushing a vehicle and wants to slow down due to an obstacle in front, the user's usual action is to pull the vehicle backward in an attempt to slow it down. Therefore, by controlling the output power based on the backward pulling force, the vehicle can be controlled to make it more responsive.

[0073] Similarly, when deceleration is required, a larger backward pull is usually applied if the user wants to decelerate quickly, and a smaller backward pull is usually applied if the user does not need to decelerate quickly.

[0074] When the force signal is a forward thrust signal, the output power can be increased according to the specific thrust value. Optionally, when it is a thrust signal, the output power is increased. The amount of increase in output power is related to the forward thrust value. The larger the forward thrust value, the larger the increase in output power; the smaller the forward thrust value, the smaller the increase in output power.

[0075] Optionally, the controller 102 can set corresponding switches for different ranges of forward thrust values, turn on the switches corresponding to the ranges of forward thrust values ​​to obtain the increase in output power, thereby determining the output power.

[0076] The reason for increasing output power based on the forward thrust signal is that when a user pushes a vehicle and wants to accelerate, the user's usual operation is to push the vehicle forward forcefully in an attempt to speed up. Therefore, by controlling the output power based on the forward thrust, the vehicle can be controlled to make it more responsive.

[0077] Similarly, when acceleration is required, a larger forward thrust is usually applied if the user wants to accelerate quickly, and a smaller forward thrust is usually applied if the user does not need to accelerate quickly.

[0078] By reducing output power based on a backward pulling force signal, the vehicle can be decelerated promptly according to user needs to avoid collisions with obstacles ahead. By increasing output power based on a forward pushing force signal, the vehicle can be accelerated promptly according to user needs to enable the user to complete the vehicle pushing operation as quickly as possible.

[0079] In one embodiment, the push force sensor 105 is located at the pivot position of the electric mobility scooter, or the push force sensor 105 is located at the throttle position of the electric mobility scooter.

[0080] Figure 3 This is a structural schematic diagram of an electric mobility scooter provided in this application, with reference to... Figure 3 The push force sensor 105 can be installed at the pivot point of the electric mobility scooter. Alternatively, the push force sensor 105 can also be installed at the throttle handle.

[0081] When the trolley force sensor 105 is set at the pivot position, it can directly sense the change in torque on the pivot when pushing the trolley, thereby ensuring that the trolley force sensor 105 can capture subtle force changes and improve the accuracy of the measurement.

[0082] Since the throttle is the part that the user directly operates when pushing the cart, setting the cart force sensor 105 in the throttle position can obtain the user's operating intention in real time, detect the user's operating intention more quickly, and thus adjust the output power more quickly to ensure the safety of pushing the cart.

[0083] By placing the trolley force sensor 105 at the aforementioned location, a precise force signal can be detected, thereby improving the accuracy of the obtained output power.

[0084] like Figure 2 As shown, in one embodiment, the propulsion assist system further includes: a battery unit 106, which provides energy to the power module 103; the battery unit 106 is connected to the controller 102;

[0085] The controller 102 is also used to control the output power applied to the power module 103 according to the acquired power signal when providing pushing assistance.

[0086] The output power can also be related to the battery capacity of the battery unit 106. When the battery capacity is low, the output power can be appropriately reduced when pushing the vehicle in order to ensure the range of the subsequent riding process. When the battery capacity is high, it will not affect the range of the subsequent riding process, so there is no need to reduce the output power when pushing the vehicle.

[0087] The remaining power of the battery cell 106 can be obtained through the battery management system, and the remaining power can be transmitted to the controller 102 in the form of a power signal. The controller 102 can control the output power based on the power signal.

[0088] By acquiring the power signal, the output power can be controlled, allowing for flexible power output based on the power level, thus balancing the vehicle's riding range and pushing assistance.

[0089] In one embodiment, the pushing assist system further includes a braking component 107, which is connected to the controller 102;

[0090] The braking component 107 is used to provide braking force for the electric mobility scooter;

[0091] The controller 102 is also used to stop providing push assist when it detects that the braking component 107 is providing braking force.

[0092] The push-assist system also includes a braking component 107, which provides braking force to slow the vehicle down when the user applies the brakes. Upon detecting that the braking component 107 is providing braking force, the controller 102 indicates that the user wishes the vehicle to stop and therefore ceases push-assistance.

[0093] Specifically, when push-assist is stopped, the system will respond to the user's throttle input. However, when push-assist is active, the system will not respond to the user's throttle input.

[0094] By stopping push-assist when braking is detected, the vehicle can be brought to a quick stop, thus fulfilling the user's intention to keep the vehicle stationary.

[0095] In one embodiment, the controller 102 is further configured to stop providing pushing assistance when it receives a slope signal indicating that the electric mobility scooter is in a downhill state.

[0096] Furthermore, when the vehicle is going downhill, the push assist can be stopped to prevent accidental acceleration. Specifically, the slope signal output by the gyroscope sensor 104 indicates whether the vehicle is going downhill, and when the controller 102 determines that the vehicle is going downhill, it can stop providing push assist.

[0097] In addition, when going downhill, if the user does not want the vehicle to accelerate downhill freely, they can apply the brakes to control the vehicle to slowly pass through the downhill section.

[0098] By stopping push assist when the vehicle is detected to be going downhill, accidental acceleration while going downhill can be avoided, improving the safety of the vehicle and the user.

[0099] In one embodiment, the pushing assistance system further includes an instrument 108, which is provided with a light-emitting unit and a sound-emitting unit; the light-emitting unit and the sound-emitting unit in the instrument 108 are respectively connected to the controller 102;

[0100] The controller 102 is also used to control the light-emitting unit to emit light when providing pushing assistance, and / or to control the sound-emitting unit to emit a first preset prompt sound;

[0101] The controller 102 is also used to control the light-emitting unit to stop emitting light when the pushing assistance stops, and / or to control the sound-emitting unit to emit a second preset prompt sound.

[0102] When the power module 103 provides push assist or not, it can be displayed on the instrument panel 108 so that the user can know whether push assist is currently being provided to the vehicle.

[0103] Specifically, a light-emitting unit and a sound-emitting unit can be installed on the instrument 108. The light-emitting unit and the sound-emitting unit can be connected to the controller 102 respectively. Specifically, when pushing assistance is provided, the controller 102 can control the light-emitting unit to light up and control the sound-emitting unit to emit a first preset prompt sound. When pushing assistance is stopped, the controller 102 can control the light-emitting unit to stop lighting up and control the sound-emitting unit to emit a second preset prompt sound.

[0104] Optionally, when the light-emitting unit emits light and the sound-emitting unit emits the first preset prompt tone, they can emit light and sound at the same frequency.

[0105] By providing audible and visual prompts on the instrument panel 108 when pushing assistance is provided and not provided, users can be informed whether pushing assistance is currently provided, thus facilitating subsequent control of the vehicle.

[0106] This utility model also provides an electric mobility scooter, including the pushing assistance system and power module of the aforementioned embodiment, wherein the power module is used to provide output power under the control of the pushing assistance system.

[0107] Optional electric mobility scooters can be electric two-wheelers, electric scooters, balance bikes, electric-assisted bikes, etc.

[0108] The electric mobility scooter provided in this application can flexibly control the output power provided by the power module, avoiding the provision of the same output power in different scenarios and improving the user's pushing experience under different road conditions.
