Controller installation structure

Abstract

This application provides a mounting structure for a controller. The controller is electrically connected to the motor of the power assist component, controlling the motor's output and adjusting the level of assistance based on the rider's input (such as cadence and pedaling force). The controller monitors and analyzes riding conditions (such as speed and cadence) to determine whether additional electric assistance is needed. For example, when the rider feels fatigued, the controller increases the motor's power output, thereby reducing the rider's burden. By mounting the controller on the frame, the complex installation process of mounting the controller within the wheel drive assembly in traditional structures is avoided. When it is necessary to install, repair, or replace the controller, only the controller on the frame needs to be addressed, reducing the hassle of disassembling the wheels or drive assembly.

Description

Technical Field

[0001] This application relates to the field of electric bicycles, and more particularly to a mounting structure for a controller. Background Technology

[0002] A traditional bicycle consists of a frame, wheels, a transmission system, a braking system, and pedals. By pedaling, the bicycle moves around an axis, which drives the transmission system to propel the entire bicycle, thus achieving the purpose of riding.

[0003] However, traditional bicycles lack a power assist system, requiring riders to rely entirely on manual drive during the ride. This can be extremely tiring, especially during long rides or uphill climbs.

[0004] Existing electric-assist bicycles are equipped with an electric assist system by setting up an electric motor, battery, controller, and sensors. During the rider's use, the electric assist system automatically adjusts the output power of the electric motor according to the pedaling force and speed. When the rider needs assistance, the electric motor outputs assistance to help the rider exercise and reduce the rider's workload.

[0005] Electric power steering systems are all located inside the drive assemblies of the wheels. If the controller needs to be installed or repaired, the drive assemblies of the wheels must be disassembled or installed one by one to expose the controller to the outside for repair. Furthermore, during installation, the drive assemblies of the wheels must first be disassembled one by one before the controller is installed onto them. This makes the installation and disassembly of the controller extremely complex and inefficient. Utility Model Content

The controller monitors and analyzes the riding status (such as speed and cadence) to determine whether additional electric assistance is needed. For example, when the rider feels fatigued, the controller increases the motor's power output, thereby reducing the rider's burden.

[0041] By mounting the controller on the chassis, the complex installation process of mounting the controller within the wheel drive assembly, as is common in traditional designs, is avoided. When the controller needs to be installed, repaired, or replaced, only the controller on the chassis needs to be addressed, reducing the hassle of disassembling the wheels or drive assembly.

[0054] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0055] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0056] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] Embodiments of this application provide a mounting structure 100 for a controller 140, comprising:

[0058] Frame 110.

[0059] The drive assembly 120 is mounted on the frame 110 and is connected to the frame 110 in a transmission manner.

[0060] The power assist component 130 is installed between the drive component 120 and the frame 110, and is connected to the drive component 120 in a transmission manner.

[0061] The controller 140 is mounted on the frame 110 and is electrically connected to the power assist assembly 130.

[0062] Please refer to Figures 1-5 In this embodiment, the controller 140 is electrically connected to the motor of the power assist assembly 130, controlling the output of the motor and adjusting the level of assistance based on the rider's input (such as cadence and pedaling force). The controller 140 monitors and analyzes the riding status (such as speed and cadence) to determine whether additional electric assistance is needed. For example, when the rider feels fatigued, the controller 140 increases the power output of the motor, thereby reducing the rider's burden.

[0063] By mounting the controller 140 on the frame 110, the complex installation process of mounting the controller 140 inside the wheel drive assembly 120 in the traditional structure is avoided. When it is necessary to install, repair or replace the controller 140, only the controller 140 on the frame 110 needs to be handled, reducing the trouble of disassembling the wheels or drive assembly 120.

[0064] The controller 140 is mounted on the frame 110, which facilitates electrical connection and commissioning with other parts of the electric power assist system (such as the battery and sensors), and also facilitates routine inspections, firmware updates or troubleshooting.

[0065] It should be noted that the controller 140 is roughly disc-shaped and is either a PCB board or a control box.

[0066] The frame 110 is the traditional existing frame 110 structure, which will not be described in detail here.

[0067] In at least one embodiment of this application, the mounting structure 100 of the controller 140 further includes:

[0068] A water bottle cage assembly 150 is mounted on the frame 110, and a controller 140 is mounted on the bottom of the water bottle cage assembly 150.

[0069] Please refer to Figures 1-5In this embodiment, the water bottle cage assembly 150 is first fixed to the frame 110, which typically includes components such as a steering column, seat post, and crossbar. The water bottle cage is installed on any of these components via a fastener 153. This installation position can be selected according to actual needs, usually at the front of the frame 110 near the rider for easy operation and maintenance.

[0070] The controller 140 is mounted on the bottom of the kettle cage assembly 150. The bottom of the kettle cage assembly 150 provides a dedicated location for accommodating the controller 140. The controller 140 is securely fixed to the kettle cage assembly 150 by means of fixing structures (such as bolts, clips, etc.), making the installation of the controller 140 easier.

[0071] The controller 140 is mounted on the bottom of the bottle cage assembly 150 on the frame 110, allowing for easy removal and replacement. Riders or maintenance personnel can operate the controller 140 directly without removing the wheels or drive assembly 120, improving maintenance efficiency. The controller 140 can be easily removed for replacement or repair simply by unscrewing the retainer 153 of the bottle cage assembly 150.

[0072] By mounting the controller 140 on the bottle cage assembly 150, it is easier to route cables to other parts of the frame 110, such as the battery and sensors. This helps reduce cable tangling or crossing and prevents cables from being subjected to external friction or damage.

[0073] In at least one embodiment of this application, the kettle rack assembly 150 includes:

[0074] The frame 151 has a receiving cavity 150a, and the controller 140 is fixed to the bottom of the frame 151.

[0075] Clip 152 is installed on the frame 151 and forms the receiving cavity 150a with the frame 151.

[0076] The fastener 153 is fixed at one end to the frame 151 and at the other end to the vehicle frame 110.

[0077] Please refer to Figures 1-5 In this embodiment, one end of the fastener 153 is fixed to the frame 151, and the other end is connected to the frame 110. The fastener 153 ensures that the entire bottle cage assembly 150 is securely mounted on the frame 110, and serves to support and bear weight.

[0078] The frame 151 is the main part of the water bottle holder assembly 150. It not only provides a support surface to accommodate the controller 140, but also forms a receiving cavity 150a by cooperating with the clip 152, which is usually used to place water bottles or other vehicle accessories.

[0079] The controller 140 is fixed to the bottom of the frame 151. The bottom of the frame 151 is designed with a special mounting position, which can securely mount the controller 140 below it. This does not occupy other space in the frame 110 and ensures the stability of the controller 140.

[0080] Clip 152 is installed on the frame 151, together with the frame 151, forming a receiving cavity 150a, which can be used to hold items such as kettles. Clip 152 not only fixes the position of the receiving cavity 150a, but also enhances the structural stability of the entire kettle rack.

[0081] During use, the controller 140 is located at the bottom of the frame 151 and does not interfere with the basic function of the bottle cage. The bottle cage assembly 150 continues to function as a container for water bottles, while the controller 140 controls the power assist system via electrical connection. The frame 110 is connected to the frame 151 via the fastener 153, ensuring the stability of the bottle cage and securing the controller 140 securely.

[0082] If the controller 140 needs to be repaired or replaced, only the bottle cage assembly 150 needs to be removed; there is no need to disassemble the wheels or other drive components. By loosening the connection between the retainer 153 and the frame 110, the bottle cage assembly 150 can be easily removed, and the controller 140 can be easily disassembled and replaced.

[0083] The controller 140 is installed at the bottom of the frame 151, integrated with the bottle cage assembly 150, making the installation of the controller 140 very simple, without the need to disassemble the wheels or complex drive components. During maintenance, only the bottle cage assembly 150 needs to be removed, reducing manual operation steps and improving maintenance efficiency.

[0084] Because the controller 140 is cleverly concealed beneath the bottle cage, the appearance is cleaner and more aesthetically pleasing. The integrated design of the bottle cage and controller 140 makes the frame look simpler, preventing the external controller 140 from affecting the overall aesthetics of the frame 110. It also makes the overall structure more integrated, reducing the exposure of external accessories.

[0085] In at least one embodiment of this application, the frame 151 includes:

[0086] The controller 140 is fixed to the base 1511.

[0087] A connector 1512 extends along the side of the base 1511 away from the drive assembly 120. The clip 152 bends from both sides of the connector 1512 to form an annular accommodating cavity 150a. The connector 1512 is fixedly connected to the fixing member 153.

[0088] Please refer to Figures 1-5 In this embodiment, the controller 140 is fixed by a base 1511, which allows the controller 140 to be directly mounted on it, ensuring the stability of the controller 140. The base 1511 typically has sufficient rigidity and load-bearing capacity to support the controller 140 in maintaining stability under vibration or external forces.

[0089] The connector 1512 extends along one side of the base 1511. The main function of the connector 1512 is to provide a support structure so that the frame 151 can be fixedly connected to the frame 110. The connector 1512 provides support for the frame 151 through its extension, so that the clip 152 can be fixed on the frame 151 and form an accommodating cavity 150a.

[0090] Clips 152 are installed on both sides of connector 1512 and bend outward to form an annular receiving cavity 150a. This receiving cavity 150a is used to hold a kettle or other items, and the function of clips 152 is to fix the two sides of the receiving cavity 150a and maintain its shape.

[0091] The controller 140 is fixed to the base 1511, and the controller 140 is connected to the frame 151 through the base 1511, thereby obtaining stable support. The base 1511 provides sufficient space and bearing surface to ensure that the controller 140 can be firmly fixed.

[0092] The connector 1512 is connected to the fixing member 153. One end of the fixing member 153 is fixed to the connector 1512 on the frame 151, and the other end is fixed to the frame 110. The frame 151 is securely installed on the frame 110, ensuring that the entire water bottle cage assembly 150 is stably connected to the frame 110 and withstands external forces during riding.

[0093] The base 1511 provides a sturdy foundation, ensuring that the controller 140 is not affected by external vibrations or impacts during use, reducing the risk of the controller 140 becoming loose or falling off. The combination of the base 1511 and the controller 140 ensures its robustness, enabling the controller 140 to maintain stable operation during long-term use.

[0094] The connector 1512 provides additional support by extending along the base 1511, enabling the entire bottle cage assembly 150 to better withstand vibration loads during riding and enhancing the structural strength of the frame 151.

[0095] The clip 152 forms a ring-shaped cavity 150a, allowing the bottle holder to accommodate items such as water bottles while effectively securing the controller 140 to the base 1511. By fixing the controller 140 to the bottom of the frame 151, the space of the frame 110 is fully utilized, resulting in a more compact overall layout and avoiding wasted space in the frame 110.

[0096] By fixing the controller 140 to the base 1511 and using the connector 1512 and the fastener 153 to achieve a stable connection between the bottle holder assembly 150 and the frame 110, the frame 151 not only enhances the stability of the controller 140, but also improves the reliability of the overall structure.

[0097] In at least one embodiment of this application, the base 1511 includes:

[0098] The housing 1513 has a receiving groove 1513a at one end near the drive assembly 120, and the controller 140 is housed in the receiving groove 1513a.

[0099] End cap 1514 is fixedly connected to housing 1513 and covers receiving groove 1513a. The connection line of controller 140 extends to the outside through end cap 1514.

[0100] Please refer to Figures 1-5 In this embodiment, the main part of the base 1511 is the housing 1513, which forms a container for mounting the controller 140. The housing 1513 allows the controller 140 to be securely housed within it and provides necessary support and protection. One end of the housing 1513 is located near the drive assembly 120, where a receiving groove 1513a is formed to provide a suitable mounting space for the controller 140.

[0101] The receiving slot 1513a is a space provided within the base 1511 for the controller 140, which is placed within this slot. The receiving slot 1513a ensures that the controller 140 is securely fixed within the base 1511, preventing changes in the position of the controller 140 or loosening due to vibration or external forces.

[0102] End cap 1514 is connected to base 1511 and covers receiving groove 1513a. The function of end cap 1514 is to close the receiving groove 1513a of controller 140, providing additional protection so that controller 140 is not easily affected by external contamination (such as dust, water droplets, etc.) in the groove, while ensuring that controller 140 remains stable.

[0103] The controller 140 is electrically connected to other systems (such as batteries, motors, sensors, etc.) via connecting cables. The connecting cables extend from the controller 140 within the housing 1513a, pass through the end cover 1514, and finally extend to the outside to connect with external devices.

[0104] The controller 140 is fixed in the receiving groove 1513a of the base 1511, and the end cover 1514 covers the receiving groove 1513a, safely encapsulating the controller 140 therein, ensuring that the controller 140 will not be affected by external interference or physical damage during operation.

[0105] A connection cable extends from the controller 140 and connects to external devices through a hole or dedicated channel in the end cap 1514. The controller 140 can receive power and signals from external devices such as batteries and sensors, and simultaneously feed control information back to the system.

[0106] During installation, the controller 140 is placed into the receiving slot 1513a of the base 1511, and the end cover 1514 is installed on the housing 1513, completely sealing the receiving slot 1513a. The connecting wires pass through the end cover 1514 to ensure unobstructed electrical connections.

[0107] If the controller 140 needs to be replaced or maintained, the end cover 1514 can be removed, the controller 140 can be taken out and reconnected or replaced. Since the end cover 1514 covers the receiving slot 1513a, the connection wires of the controller 140 will not be damaged or interfered with during normal use, ensuring that the maintenance process is simple and safe.

[0108] The receiving groove 1513a and the end cap 1514 effectively protect the controller 140 from external physical damage. The receiving groove 1513a can firmly fix the controller 140 in the base 1511, while the end cap 1514 further seals the receiving groove 1513a to prevent external factors such as dust, moisture and humidity from affecting the controller 140.

[0109] The controller 140 is installed in the receiving slot 1513a and closed by the end cover 1514, making the entire installation process simple and efficient. Since the end cover 1514 can be removed, maintenance can be performed simply by removing the end cover 1514 to easily access the controller 140 for inspection or replacement, avoiding the need to disassemble the entire system or perform complex operations.

[0110] It simplifies the installation and maintenance process, reduces manual operation steps, improves maintenance efficiency, and also reduces the risk of damage that may be caused by complex disassembly operations.

[0111] It should be noted that the shell 1513 is roughly circular, with one side recessed to form a circular receiving groove 1513a; the end cap 1514 is roughly circular in shape; the connector 1512 is roughly arc-shaped vertical plate, with the arc-shaped surface fitting onto the frame 110; the clamping piece 152 is an arc-shaped piece, and the two clamping pieces 152 are symmetrically arranged to form an approximately circular structure.

[0112] In at least one embodiment of this application, the fastener 153 includes:

[0113] The fitting part 1531 is fitted onto the frame 110 and is fixedly connected to the connector 1512.

[0114] The clamping portion 1532 is formed by bending from both sides of the fitting portion 1531, and a mounting cavity 1532a is formed between the clamping portion 1532 and the fitting portion 1531, and the frame 110 is located in the mounting cavity 1532a.

[0115] Please refer to Figures 1-5 In this embodiment, the fitting part 1531 contacts the frame 110 and is directly fixedly connected. This ensures a good contact surface between the fastener 153 and the frame 110, providing stable support.

[0116] The clamping portion 1532 is bent from both sides of the fitting portion 1531, firmly clamping the frame 110 in the fixing member 153. The clamping portion 1532 and the fitting portion 1531 together form a mounting cavity 1532a, which can accommodate a part of the frame 110. The clamping portion 1532 ensures that the frame 110 is securely clamped, preventing loosening or displacement caused by external forces.

[0117] The mounting cavity 1532a is a space enclosed by the fitting part 1531 and the clamping part 1532, and the frame 110 is placed in this cavity. This ensures that the frame 110 is firmly fixed in it, preventing unnecessary displacement of the frame 110 due to vibration or external force during use.

[0118] During installation, the fitting portion 1531 of the fastener 153 first contacts and securely connects to the frame 110. Next, the clamping portion 1532 is bent and surrounds both sides of the frame 110, and the mounting cavity 1532a formed by the clamping portion 1532 and the fitting portion 1531 firmly holds the frame 110 within it. The frame 110 is securely fixed within the mounting cavity 1532a, and the fastener 153 effectively supports and secures the entire bottle cage assembly 150 or controller 140 assembly.

[0119] The fastener 153, through the cooperation of the fitting part 1531 and the clamping part 1532, firmly clamps the frame 110 within the mounting cavity 1532a. This secure connection of the frame 110 ensures the stability of the mounted components, preventing loosening or detachment due to vibration, external force, or improper operation. The fastener 153 keeps the bottle cage assembly 150 or the controller 140 assembly stable during riding, ensuring the reliability and safety of the system.

[0120] When disassembly or maintenance is required, the user only needs to remove the fastener 153 and remove the clamping part 1532 from the frame 110. This makes the repair or replacement process very simple, without the need to disassemble other complex parts such as wheels and drive components 120, saving time and effort.

[0121] It should be noted that the fastener 153 is roughly a ring-shaped clamp structure.

[0122] In at least one embodiment of this application, the clamping part 1532 is provided with a through hole 1532b.

[0123] The kettle rack assembly 150 also includes:

[0124] The locking assembly 154 includes a first locking member and a locking nut. The first locking member passes through the two clamping portions 1532 and abuts against one of the clamping portions 1532. The locking nut abuts against the other clamping portion 1532 and is threadedly connected to the first locking member.

[0125] The range extender battery 155 is installed in the accommodating cavity 1532a and is electrically connected to the controller 140.

[0126] Please refer to Figures 1-5 In this embodiment, the clamping part 1532 is provided with a through hole 1532b, and the presence of the through hole 1532b allows the locking component 154 to pass through the clamping part 1532.

[0127] When the locking assembly 154 is installed, the first locking member passes through the through hole 1532b through the two clamping parts 1532, and the locking nut securely fixes it, ensuring that the connection between the water bottle cage assembly 150 and the frame 110 is firm and without loosening.

[0128] The locking nut provides additional securing force. During riding, the locking assembly 154 prevents any loosening caused by vibration or external force through the tightening of the threads, thereby ensuring the stability and safety of the water bottle cage.

[0129] If it is necessary to disassemble the bottle cage assembly 150, the locking nut can be easily loosened and the first locking element removed, allowing the bottle cage assembly 150 to be separated from the frame 110. Due to the design of the locking assembly 154, the disassembly process is simple and convenient, requiring no complicated tools.

[0130] During maintenance, simply reconnect the locking components and tighten the locking nuts to re-secure the kettle rack assembly 150, ensuring its stability.

[0131] The threaded connection between the locking nut and the first locking element provides strong securing force, ensuring the bottle cage assembly 150 is very stable after installation and preventing loosening or detachment due to vibration or external forces during riding. The overall structural integrity is ensured by the locking element passing through and securing both clamping parts 1532.

[0132] The locking assembly 154 simplifies the installation and removal process of the bottle cage assembly 150. By tightening and loosening the locking nut, users can easily install and remove the bottle cage without complicated tools or disassembly steps. This significantly improves assembly efficiency and saves time.

[0133] Because the locking nut can be tightened or loosened with a simple rotation, the maintenance process becomes highly efficient. When replacing, cleaning, or repairing the kettle cage assembly 150, the user only needs to loosen the locking nut and disassemble the assembly to perform the operation, avoiding the hassle of disassembling numerous other parts.

[0134] During prolonged use, the locking assembly 154 effectively prevents any loosening caused by vibration or external force due to the threaded structure of the locking nut. Especially during harsh road conditions or high-speed riding, the threaded connection ensures a secure connection, thereby reducing potential safety hazards caused by loose parts.

[0135] The range extender battery 155 is installed in the accommodating cavity 1532a by snapping or placing, and is electrically connected to the controller 140 via an electrical connection cable. When assistance is needed, the range extender battery 155 can provide power to the drive component 120. At the same time, the range extender battery 155 is installed in the accommodating cavity 1532a by snapping or placing, which makes disassembly and installation more convenient and facilitates the installation and replacement of the range extender battery 155.

[0136] It should be noted that the locking assembly 154 consists of a bolt and a nut.

[0137] In at least one embodiment of this application, the frame 110 includes a steering rod, a seat rod, and a crossbar, and the controller 140 is mounted on the steering rod, the crossbar, or the seat rod, wherein the steering rod is fixedly connected to the seat rod and the crossbar.

[0138] Please refer to Figures 1-5 In this embodiment, the steering lever is a component used by the rider to control the direction of the bicycle. It is usually located in the handlebar area and is responsible for the rotation of the wheels and direction adjustment.

[0139] The seatpost, which connects the seat to the frame 110, bears the rider's weight and is a key component for maintaining riding stability.

[0140] The crossbar, which connects the steering column and seat post, ensures the overall rigidity of the frame 110 and provides stable support for the rider.

[0141] The controller 140 is mounted on the steering column, seat post, or crossbar. The controller 140 can be located anywhere on the frame 110, depending on the design and riding requirements.

[0142] The controller 140 is mounted on the steering bar, seat bar, or crossbar on the frame 110, which not only facilitates electrical connection but also ensures that the controller 140 is not subjected to excessive vibration or external forces during riding, thus ensuring the stability of the system.

[0143] Mounting the controller 140 on the steering rod, seat post, or crossbar of the frame 110 ensures that it maintains appropriate connection distance and electrical communication with other components of the electric power assist system, such as the battery and motor. This not only avoids mounting the controller 140 near wheels that are susceptible to vibration or impact, but also allows the controller 140 to better protect itself from external environmental influences, improving the overall system reliability.

[0144] The controller 140 requires a tight electrical connection with the battery and motor, and the locations on the frame 110 (steering pole, seat post, or crossbar) provide convenient wiring paths. This simplifies the electrical connections, reducing exposed wires and lowering the risk of electrical faults due to improper wiring.

[0145] Since the controller 140 is mounted on the frame 110, riders can easily adjust or replace it, especially when upgrading or replacing the controller 140, without having to disassemble the complex wheel or drive system, saving time.

[0146] In at least one embodiment of this application, the driving component 120 includes:

[0147] The drive gear 121 is rotatably mounted on the frame 110.

[0148] Driven gear 122 is rotatably mounted on the frame 110.

[0149] Chain 123 is sleeved on the drive gear 121 and the driven gear 122, and is connected to the drive gear 121 and the driven gear 122 respectively.

[0150] Please refer to Figures 1-5 In this embodiment, the rider provides mechanical energy by pedaling, driving the sprocket 121 to rotate. The driven sprocket 122 corresponds to the driven sprocket 121 and is also mounted on the frame 110, but it is not directly driven by the rider. It is connected to the driven sprocket 121 via a chain 123, and the driven sprocket 122 rotates as the driven sprocket 121 rotates.

[0151] The chain 123 connects the drive sprocket 121 and the driven sprocket 122. It is fitted between the drive sprocket 121 and the driven sprocket 122, and transmits power to make the driven sprocket 122 rotate, thereby driving the rear wheel of the bicycle.

[0152] When the rider pedals, the movement of the pedal connected to the crank rotates the drive sprocket 121.

[0153] When the drive gear 121 rotates, the chain 123 moves together with the rotation of the drive gear 121, and the drive gear 121 transmits the rotational power to the driven gear 122 through the chain 123.

[0154] The movement of the chain 123 causes the driven sprocket 122 to start rotating. The driven sprocket 122 is usually connected to the rear wheel of the wheel through the wheel axle. Therefore, the rotation of the driven sprocket 122 drives the rear wheel to rotate, ultimately enabling the rider to move.

[0155] The controller 140 monitors the rider's pedaling force, cadence, and other information, and sends commands to the motor when needed to increase electric assist. The motor provides additional power support to the rider through a transmission connection with the drive sprocket 121.

[0156] It should be noted that both the drive gear 121 and the driven gear 122 are existing gear 121s, and will not be described in detail here. The chain 123 is an existing structure, and will not be described in detail here.

[0157] In at least one embodiment of this application, the assist component 130 includes:

[0158] A drive motor is mounted on the frame 110 and rotatably connected to the driven gear 122. The drive motor is electrically connected to the controller 140.

[0159] The power supply is electrically connected to the drive motor.

[0160] Please refer to Figures 1-5In this embodiment, when the cyclist is riding, the controller 140 adjusts the power output of the drive motor in real time according to the cyclist's pedaling movements, thereby achieving electric assist. The motor provides additional power according to the instructions of the controller 140, reducing the cyclist's fatigue, especially when climbing hills or accelerating, the motor can effectively improve riding efficiency.

[0161] With the support of the power supply, the drive motor can continuously provide power, making it easier for riders to complete long-distance rides.

[0162] With the assistance of the drive motor, cyclists can easily handle inclines and long rides without expending excessive physical energy. The controller 140 automatically adjusts the motor output according to the cyclist's needs, allowing the cyclist to focus solely on pedaling while the system provides the appropriate amount of electric support as needed.

[0163] The intelligent adjustment function of the controller 140 can adjust the output power of the electric motor according to the rider's needs. When more assistance is needed (such as climbing or accelerating), the controller 140 will automatically increase the motor output; while when the rider reduces the cadence, the controller 140 will reduce the power output of the electric motor, thereby maximizing system efficiency and avoiding unnecessary energy waste.

[0164] The drive motor is an electric motor, and the power source is a battery.

[0165] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
