Description

Technical Field

[0001] The invention belongs to the technical field of children's vehicles, and in particular relates to a children's drift vehicle. Background Art

[0002] With the development of society and the improvement of people's living standards, the variety of children's toys is becoming increasingly diverse, and the requirements for functionality, safety, and fun are also becoming higher and higher. Traditional children's toy vehicles, such as tricycles and four-wheeled bicycles, are relatively simple in structure and function, mainly focusing on simple mobility functions, and cannot meet children's needs for entertainment and challenges.

[0003] In recent years, drift cars have become a favorite among children and teenagers due to their unique drifting capabilities. However, existing children's drift cars have numerous structural design deficiencies. For example, some drift cars utilize four-wheel drive, resulting in poor steering flexibility and difficulty achieving fast and smooth drifting maneuvers. Other drift cars have an unreasonable wheel layout, resulting in poor driving stability and prone to rollover, posing a safety hazard. Furthermore, some drift cars lack structural strength, making them ineffective in protecting children in the event of a collision.

[0004] In view of the above problems, it is necessary to improve them. Summary of the Invention

[0005] The purpose of the present invention is to provide a children's drift car, which solves the problems of existing children's drift cars such as inflexible steering, poor stability, and low safety through a unique wheel assembly layout, an optimized direction control mechanism, a reinforced body structure, and a complete anti-collision design, and provides children with a drift toy car that is both safe and fun.

[0006] In order to achieve the above objectives, the technical solution adopted by the patent of the present invention is: a children's drift car, including a car body, a wheel assembly arranged at the bottom of the car body, a seat arranged at the middle and rear part of the car body, a driving mechanism arranged at the bottom of the seat and a direction control mechanism arranged at the front part of the car body for controlling the steering of the drift car; the wheel assembly includes a front drive single wheel installed at the bottom end of the front part of the car body and a left rear wheel and a right rear wheel installed at the rear end of the car body; the direction control mechanism is connected to the front drive single wheel; the driving mechanism is used to drive the front drive single wheel to rotate; the wheel assembly also includes a left front wheel and a right front wheel installed at the bottom end of the front part of the car body; the left front wheel, the right front wheel, the left rear wheel and the right rear wheel are all universal wheels.

[0007] The front drive wheel is mounted at the bottom front end of the vehicle body and is driven by a drive mechanism located under the seat, providing forward propulsion. The front drive wheel is also connected to a steering mechanism, which controls the vehicle's direction of travel.

[0008] The seats in this solution are arranged in the middle and rear part of the vehicle body to provide a seating position for children.

[0009] The left front wheel and the right front wheel in this solution are also installed at the bottom end of the front of the vehicle body, and together with the front drive single wheel constitute the wheel structure of the front of the vehicle; the left front wheel and the right front wheel are universal wheels. The design of this universal wheel allows the front wheels to flexibly change direction during the drifting process, assisting the front drive single wheel to achieve fast and smooth steering movements; and, in the initial state of the children's drift car, the left front wheel and the right front wheel do not contact the ground. This design helps to rely solely on the front drive single wheel to drive the vehicle forward when the vehicle starts. When the vehicle performs actions such as drifting, the left front wheel and the right front wheel will contact the ground to provide steering assistance.

[0010] The left and right rear wheels in this solution are mounted at the rear end of the vehicle body and are also universal wheels. The distance between the left and right rear wheels is greater than the distance between the left and right front wheels. This unique wheel spacing design lowers the vehicle's center of gravity, significantly improving driving stability and effectively reducing the risk of rollover during drifting. Furthermore, the left and right rear wheels are mounted at the bottom of a transverse reinforcement bar installed in a positioning slot at the bottom of the vehicle body, further enhancing the structural strength of the wheel mounting area.

[0011] As a preferred solution of the present invention, the front drive single wheel is located between the left front wheel and the right front wheel along the width direction of the vehicle body; this layout makes the force distribution more uniform when the vehicle turns, which helps to improve the vehicle's handling performance.

[0012] As a preferred solution of the present invention, the distance between the left rear wheel and the right rear wheel is greater than the distance between the left front wheel and the right front wheel.

[0013] As a preferred solution of the present invention, in the initial state of the children's drift car, the left front wheel and the right front wheel are not in contact with the ground; the front drive single wheel and the left rear wheel and the right rear wheel are on the same horizontal plane.

[0014] As a preferred solution of the present invention, a positioning groove is formed at the bottom of the vehicle body, and a reinforcement component is assembled in the positioning groove; the reinforcement component includes a transverse reinforcement rod and a longitudinal reinforcement rod; the transverse reinforcement rod and the longitudinal reinforcement rod are fixedly connected, wherein the left rear wheel and the right rear wheel are installed at the bottom of the transverse reinforcement rod.

[0015] In this solution, the transverse reinforcement rod and the longitudinal reinforcement rod are fixedly connected to each other to form a cross-shaped reinforcement structure; this reinforcement structure can effectively enhance the strength and rigidity of the bottom of the vehicle body, and improve the overall load-bearing capacity and anti-deformation ability of the vehicle; the left rear wheel and the right rear wheel are installed at the bottom of the transverse reinforcement rod, and through the support of the reinforcement component, the wheels are more stable during driving, reducing the impact of factors such as bumps on the vehicle body structure.

[0016] As a preferred solution of the present invention, an anti-collision bar is arranged on the vehicle body, and the anti-collision bar is connected to the vehicle body through a connecting rod.

[0017] In this solution, a crash bar is installed on the body of the vehicle and connected to the body via a connecting rod. In the event of a collision, the crash bar will first contact the obstacle, dispersing the impact force to the connecting rod and the body of the vehicle, effectively reducing damage to the internal structure of the body and children on board.

[0018] As a preferred embodiment of the present invention, the front end of the vehicle body is formed with an inclined guide plate, on which a crash buffer is fixed. The bottom of the crash buffer is curved. The crash buffer is made of PP material and has excellent elasticity and cushioning properties. In the event of a vehicle collision, it can absorb and cushion the impact force, reducing the impact on the vehicle and children. The curved structure design enables the crash buffer to better guide the vehicle's sliding direction during a collision, preventing the vehicle from violently rebounding or rotating due to the collision, further improving vehicle safety.

[0019] As a preferred solution of the present invention, the driving mechanism includes a battery driver, and the battery driver is electrically connected to the front drive wheel.

[0020] Among them, the drive mechanism is set at the bottom of the seat to drive the front drive wheel to rotate; the drive mechanism provides power for the front drive wheel; the battery drive adopts a safe and stable battery power supply system, which can provide continuous and stable power output for the vehicle, and is convenient for battery replacement and charging, making it convenient for children to use.

[0021] As a preferred solution of the present invention, the direction control mechanism includes a steering rod, and a steering wheel is installed on the top of the steering rod; a front fork with a U-shaped structure is fixed to the bottom of the steering rod, and the front drive single wheel is installed on the front fork; when the steering rod rotates, the front fork rotates accordingly, thereby driving the front drive single wheel to change direction, realizing the steering function of the vehicle; this mechanical transmission steering method has a simple structure and is easy to operate, allowing children to intuitively feel the relationship between the steering operation and the change in the vehicle's driving direction, thereby enhancing children's driving experience.

[0022] As a preferred solution of the present invention, a positioning cylinder is formed on the vehicle body, a through hole is formed in the positioning cylinder for the steering rod to pass through, a limiting partition is fixedly provided at the position of the steering rod near the front fork, the limiting partition is sleeved on the steering rod, one end of the limiting partition is connected to the limiting extension plate, a limiting block is vertically fixed on the limiting extension plate, correspondingly, a limiting groove is provided on the outside of the through hole in the vehicle body, and limiting blocks are provided at both ends of the limiting groove.

[0023] As a preferred embodiment of the present invention, a reinforcing tube is coaxially sleeved on the outer side of the positioning tube; multiple reinforcing ribs are installed between the positioning tube and the reinforcing tube; wherein, multiple reinforcing plates are fixedly installed on the outer side of the reinforcing tube and connected to the vehicle body; through the cooperation of the limiting partition, limiting extension plate, limiting block, limiting groove and limiting baffle, the rotation angle of the steering rod can be effectively limited to prevent the steering rod from excessively rotating and causing the vehicle to lose control or damage the steering control mechanism. At the same time, a reinforcing tube is coaxially sleeved on the outer side of the positioning tube, multiple reinforcing ribs are installed between the positioning tube and the reinforcing tube, and multiple reinforcing plates are fixedly installed on the outer side of the reinforcing tube and connected to the vehicle body; this reinforcement structure can significantly improve the structural strength and stability of the steering control mechanism, ensuring the accuracy and reliability of the steering operation.

[0024] The beneficial effects of the present invention are:

[0025] The present invention has a simple structure, flexibility and fun: the unique wheel layout, the front drive single wheel combined with the universal wheel design enables the drift car to achieve flexible steering and drifting functions, greatly increasing the fun of children playing and helping to cultivate children's motor coordination and control abilities.

[0026] The present invention has stability: the distance between the left rear wheel and the right rear wheel is greater than the distance between the left front wheel and the right front wheel, which reduces the risk of the vehicle rolling over; the setting of the reinforcement component enhances the structural strength of the bottom of the vehicle body, further improving the stability of the vehicle during driving.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] Example:

[0041] like Figure 1 — Figure 8As shown, the children's drift car includes a car body 1, a wheel assembly 2 arranged at the bottom of the car body 1, a seat 3 arranged at the middle and rear part of the car body 1, a driving mechanism 4 arranged at the bottom of the seat 3 and a direction control mechanism 5 arranged at the front part of the car body 1 for controlling the steering of the drift car; the wheel assembly 2 includes a front drive single wheel 6 installed at the bottom end of the front part of the car body 1 and a left rear wheel 31 and a right rear wheel 32 installed at the rear end of the car body 1; the direction control mechanism 5 is connected to the front drive single wheel 6; the driving mechanism 4 is used to drive the front drive single wheel 6 to rotate; the wheel assembly 2 also includes a left front wheel 21 and a right front wheel 22 installed at the bottom end of the front part of the car body 1; the left front wheel 21, the right front wheel 22, the left rear wheel 31 and the right rear wheel 32 are all universal wheels.

[0042] Along the width direction of the vehicle body 1 , the front drive single wheel 6 is located between the left front wheel 21 and the right front wheel 22 ; the distance between the left rear wheel 31 and the right rear wheel 32 is greater than the distance between the left front wheel 21 and the right front wheel 22 .

[0043] In the initial state of the children's drift car, the left front wheel 21 and the right front wheel 22 are not in contact with the ground; the front drive single wheel 6 and the left rear wheel 31 and the right rear wheel 32 are on the same horizontal plane.

[0044] The front drive wheel is mounted at the bottom front end of the vehicle body and is driven by a drive mechanism located under the seat, providing forward propulsion. The front drive wheel is also connected to a steering mechanism, which controls the vehicle's direction of travel.

[0045] The left front wheel and the right front wheel in this solution are also installed at the bottom end of the front of the vehicle body, and together with the front drive single wheel constitute the wheel structure of the front of the vehicle; the left front wheel and the right front wheel are universal wheels. The design of this universal wheel allows the front wheels to flexibly change direction during the drifting process, assisting the front drive single wheel to achieve fast and smooth steering movements; and, in the initial state of the children's drift car, the left front wheel and the right front wheel do not contact the ground. This design helps to rely solely on the front drive single wheel to drive the vehicle forward when the vehicle starts. When the vehicle performs actions such as drifting, the left front wheel and the right front wheel will contact the ground to provide steering assistance.

[0046] The left and right rear wheels in this solution are mounted at the rear end of the vehicle body and are also universal wheels. The distance between the left and right rear wheels is greater than the distance between the left and right front wheels. This unique wheel spacing design lowers the vehicle's center of gravity, significantly improving driving stability and effectively reducing the risk of rollover during drifting. Furthermore, the left and right rear wheels are mounted at the bottom of a transverse reinforcement bar installed in a positioning slot at the bottom of the vehicle body, further enhancing the structural strength of the wheel mounting area.

[0047] In this embodiment, the children's drift car is mainly composed of a car body 1, a wheel assembly 2, a seat 3, a driving mechanism 4 and a direction control mechanism 5.

[0048] Specifically, the body shell 1 serves as the main frame of the drift car, and a positioning groove 40 is formed at the bottom thereof for assembling a reinforcement component 7 to enhance the structural strength of the body shell; an anti-collision bar 13 is arranged on the body shell 1 and connected to the body shell 1 through a connecting rod 14 to play a collision buffering role; an inclined guide plate 10 is formed at the front end of the body shell 1, and an anti-collision buffer 11 is fixed on the guide plate 10, and the bottom of the anti-collision buffer 11 is an arc-shaped structure 12, and the anti-collision buffer 11 is a rubber buffer block or a rubber wheel, which further improves the anti-collision performance of the vehicle.

[0049] The body shell 1 is made of high-strength engineering plastics, such as PP, and is formed through an injection molding process. Before injection molding, the mold must be cleaned and preheated at a controlled temperature of 40-60°C to ensure that the plastic melt evenly fills the mold cavity. The molded body shell undergoes surface grinding and polishing to remove burrs and molding marks. Furthermore, secondary strengthening treatment is performed at key locations, such as the positioning grooves 40, the mounting holes for the anti-collision bar 13, and the connection points of the guide plate 10. This localized thickening enhances structural strength.

[0050] The wheel assembly 2 comprises a front drive single wheel 6, a left front wheel 21 and a right front wheel 22 installed at the front bottom end of the vehicle body 1, and a left rear wheel 31 and a right rear wheel 32 installed at the rear end of the vehicle body 1, wherein the left front wheel 21, the right front wheel 22, the left rear wheel 31 and the right rear wheel 32 are all universal wheels; along the width direction of the vehicle body 1, the front drive single wheel 6 is located between the left front wheel 21 and the right front wheel (22); the distance between the left rear wheel 31 and the right rear wheel 32 is greater than the distance between the left front wheel 21 and the right front wheel 22; in the initial state of the children's drift car, the left front wheel 21 and the right front wheel 22 do not contact the ground, and the front drive single wheel 6 and the left rear wheel 31 and the right rear wheel 32 are on the same horizontal plane.

[0051] The left front wheel 21, right front wheel 22, left rear wheel 31, and right rear wheel 32 are all made of wear-resistant PA and equipped with high-precision ball bearings, ensuring flexible steering and low noise. The axle of the universal wheel requires rust-proofing treatment, which can be galvanized or nickel-plated. The axle and wheel are connected by an interference fit, pressed into the center hole of the wheel using dedicated press-fitting equipment. The press-fitting pressure is controlled at 5-8kN to ensure a secure connection.

[0052] In addition to possessing the structural characteristics of a universal wheel, the front-drive single wheel 6 also requires an integrated drive motor and transmission. A small DC reduction motor is used as the motor. Gears made of high-strength nylon are used between the motor and the wheel axle. A brushless motor, preferably 200W, ensures stable power transmission.

[0053] Seat 3: arranged at the middle and rear part of the vehicle body 1, providing a seating position for children.

[0054] The driving mechanism 4 is arranged at the bottom of the seat 3 and includes a battery driver 41. The battery driver 41 is electrically connected to the front driving single wheel 6 to drive the front driving single wheel 6 to rotate and provide forward power for the drift car.

[0055] The battery driver 41 utilizes a modular design, integrating a lithium-ion battery pack, a power management chip, and a motor drive circuit. The battery pack utilizes 18650 rechargeable lithium-ion cells with a capacity of 2000-3000mAh, connected in series or parallel to meet the vehicle's voltage and power requirements. The power management chip provides overcharge, over-discharge, and overcurrent protection to ensure safe battery operation. The motor drive circuit utilizes pulse-width modulation (PWM) technology to precisely control the rotational speed of the front drive wheel at six speeds. Prior to assembly, the battery driver undergoes functional testing, including voltage output testing, charge-discharge cycle testing, and motor drive performance testing, to ensure that all indicators meet design requirements.

[0056] Steering control mechanism 5: It is arranged at the front of the vehicle body 1 and connected to the front driving single wheel 6, and is used to control the steering of the drift vehicle. The direction control mechanism 5 includes a steering rod 50, a steering wheel 51 is installed on the top of the steering rod 50, and a front fork 52 with a U-shaped structure is fixed to the bottom of the steering rod 50, and the front drive single wheel 6 is mounted on the front fork 52; a positioning cylinder 18 is formed on the vehicle body 1, and a through hole 15 is formed in the positioning cylinder 18 for the steering rod 50 to pass through. A limiting partition 53 is fixed to the steering rod 50 near the front fork 52, and the limiting partition 53 is sleeved on the steering rod 50. One end of the limiting partition 53 is connected to the limiting extension plate 54, and a limiting block 54 is vertically fixed on the limiting extension plate 54. Correspondingly, a limiting groove 16 is provided on the outer side of the through hole 15 in the vehicle body 1, and limiting blocks 17 are provided at both ends of the limiting groove 16; a reinforcing cylinder 19 is coaxially sleeved on the outer side of the positioning cylinder 18, and a plurality of reinforcing ribs 20 are assembled between the positioning cylinder 18 and the reinforcing cylinder 19, wherein a plurality of reinforcing plates 21 are fixed on the outer side of the reinforcing cylinder 19 and connected to the vehicle body 1.

[0057] The steering rod 50 is made of high-strength aluminum alloy, processed and formed by a CNC lathe, and the surface is anodized to enhance wear resistance and aesthetics; the steering wheel 51 is injection-molded by engineering plastic, and the front fork 52 is stamped by steel plate. After molding, heat treatment is required to improve the strength and toughness of the material. The heat treatment process is quenching + tempering, with the quenching temperature controlled at 850-900℃ and the tempering temperature controlled at 550-600℃.

[0058] A positioning groove 40 is formed at the bottom of the vehicle body 1, and a reinforcement assembly 7 is assembled in the positioning groove 40; the reinforcement assembly 7 includes a transverse reinforcement rod 70 and a longitudinal reinforcement rod 71; the transverse reinforcement rod 70 and the longitudinal reinforcement rod 71 are fixedly connected, wherein the left rear wheel 31 and the right rear wheel 32 are installed at the bottom of the transverse reinforcement rod 70; thereby improving the load-bearing capacity and structural strength of the bottom of the vehicle body 1.

[0059] A positioning cylinder 18 is formed on the vehicle body 1, and a through hole 15 is formed in the positioning cylinder 18 for the steering rod 50 to pass through. A limiting partition 53 is fixedly provided at the position of the steering rod 50 near the front fork 52, and the limiting partition 53 is sleeved on the steering rod 50. One end of the limiting partition 53 is connected to the limiting extension plate 54, and a limiting block 55 is vertically fixed on the limiting extension plate 54. Correspondingly, a limiting groove 16 is provided on the outside of the through hole 15 in the vehicle body 1, and limiting baffles 17 are provided at both ends of the limiting groove 16; a reinforcing cylinder 19 is coaxially sleeved on the outside of the positioning cylinder 18; a plurality of reinforcing ribs 20 are assembled between the positioning cylinder 18 and the reinforcing cylinder 19; wherein, a plurality of reinforcing plates 23 are fixedly provided on the outside of the reinforcing cylinder 19 and connected to the vehicle body 1.

[0060] The limiting baffle 53, limiting extension plate 54, and limiting stopper 55 are made of iron and welded to the steering rod 50 to ensure a reliable limiting structure. The positioning tube 18 and reinforcement tube 19 are also made of iron and manufactured through processes such as cutting, drilling, and tapping. The reinforcing ribs 20 and reinforcement plates 21 are stamped from iron sheets. The reinforcing ribs 20 are welded to the positioning tube 18 and reinforcement tube 19 using argon arc welding. The weld seam must be uniform and full, without pores or cracks. The reinforcement plates 21 are bolted to the vehicle body 1. The left and right rear wheels 31 and 32 are secured with M8×20 screws. Each reinforcement plate 21 is secured with four bolts, and the tightening torque is controlled within 2-3 N·m.

[0061] The working principle of the children's drift car is as follows:

[0062] When a child sits on the seat 3, the battery driver 41 of the drive mechanism 4 is started. The battery driver 41 converts the stored electrical energy into an electrical energy signal. The pulse width modulation (PWM) technology is used through the motor drive circuit to accurately control the current size and frequency, driving the front drive wheel 6 to rotate, thereby providing forward power for the drift car.

[0063] By turning the steering wheel 51, the child causes the steering rod 50 to rotate about the through hole 15 in the positioning cylinder 18. The U-shaped front fork 52 fixed to the bottom of the steering rod 50 rotates accordingly, and the front drive wheel 6 is mounted on the front fork 52, thereby achieving steering control of the front drive wheel 6. During the steering process, due to centrifugal force, the left front wheel 21 and the right front wheel 22, which were originally not in contact with the ground, will deflect downward and touch the ground. The left front wheel 21, the right front wheel 22, the left rear wheel 31, and the right rear wheel 32 are all universal wheels, capable of rotating freely in multiple directions. When they touch the ground, combined with the steering of the front drive wheel 6, they can cause the vehicle to slide laterally while moving forward, thus achieving a drifting effect.

[0064] At the same time, the limiting spacer 53, limiting extension plate 54, and limiting block 54 on the steering rod 50 cooperate with the limiting groove 16 provided outside the through hole 15 in the vehicle body 1 and the limiting blocks 17 at both ends. When the steering rod 50 is rotated to a certain angle, the limiting block 54 contacts the limiting block 17, thereby limiting further rotation of the steering rod 50, preventing damage to vehicle components due to oversteering and ensuring the safety and stability of the steering operation.

[0065] In actual production and manufacturing, the vehicle body 1 can be made of high-strength plastic material and formed through injection molding to ensure that it has sufficient strength and toughness; the universal wheel in the wheel assembly 2 can be made of wear-resistant and silent rubber material to ensure stability and comfort during driving; the battery driver 41 of the drive mechanism 4 can be made of a safe and environmentally friendly rechargeable lithium battery, or a lead-acid battery, which is convenient for children to use multiple times.

[0066] Before using the vehicle, check that all components are securely connected and that the battery is fully charged. Children should be supervised by an adult and should play on a flat, safe surface. Avoid areas with obstacles or crowded places to ensure safe use.

[0067] Specifically, the assembly process of the children's drift car is as follows:

[0068] 1. Install reinforcement assembly 7: Place the transverse reinforcement rod 70 and the longitudinal reinforcement rod 71 into the positioning groove 40 at the bottom of the vehicle body 1 and connect and secure them with M5 bolts. Use two bolts at each connection point and control the tightening torque to 8-10N·m. After the bolts are connected, check the verticality and horizontality of the reinforcement rods, and control the error within ±1mm.

[0069] 2. Wheel Installation: First, install the left and right rear wheels 31 and 32 on the bottom of the transverse reinforcement bar 70. Secure with M8 bolts, using four bolts per wheel. Tighten to a torque of 5-7 N·m. During installation, ensure that the wheel mounting plane is perpendicular to the transverse reinforcement bar 70, with an error within ±0.5°.

[0070] Assemble the front drive wheel 6 onto the front fork 52 and secure it with a Φ12 pin and a nut. The pin should be a standard Φ12 nut that fits directly onto the wheel. After installation, check the front drive wheel 6 for rotational flexibility to ensure it is not stuck.

[0071] Finally, install the left front wheel 21 and the right front wheel 22 in the same way as the rear wheels. Use M4 self-tapping screws to secure them, and control the tightening torque to 5-7 N·m.

[0072] 3. Installing the Drive Mechanism 4: Secure the battery drive 40 to the mounting bracket at the bottom of the seat 3 using M4 bolts, two bolts per mounting point, and tightening torque within 2-3 N·m. Connect the power cable from the battery drive 40 to the front drive wheel 6. Use a high-temperature, wear-resistant rubber-sheathed cable with a wire diameter of 1.5 mm², depending on the current. Use crimp terminals. Perform a tension test after crimping to ensure a secure connection. Ensure the power cables are neatly arranged within the vehicle body to avoid friction or interference with other components.

[0073] 4. Installing the Steering Control Mechanism 5: Insert the steering rod 50 through the through-hole 15 of the positioning cylinder 18. Ensure that the limiting spacer 53, limiting extension plate 54, and limiting block 55 are properly installed on the steering rod 50 and that they fit well with the limiting groove 16 and limiting block 17 in the vehicle body 1. Apply grease to the contact area between the steering rod 50 and the positioning cylinder 18. Use a high-temperature, wear-resistant lithium-based grease to reduce friction. Install the steering wheel 51 to the top of the steering rod 50 and secure it with an M5 nut. Finally, install the front fork 52 to the bottom of the steering rod 50, ensuring a secure connection and flexible rotation.
