[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution:

[0023] Example 1

[0024] To address the aforementioned issues: existing electric motorcycle forks use a split-type water cooling system, which requires an external independent water tank and pump, taking up space and increasing counterweight, making installation complex; passive cooling is insufficient, meaning that simply adding an air-cooled cooling fan cannot cope with the instantaneous high temperature of a high-power controller; and the piping is complex, with multiple component connections leading to increased leakage risk and difficulties in installation and maintenance.

[0025] The solution is as follows: A modular water-cooled fork with a built-in water storage chamber and water pump, including a support base 1, a bottom bracket damping bushing 2, a gasket spacer 3, a key 4, a brushless DC micro water-cooled pump 5, a water-cooled pump cover plate 6, a countersunk screw 7, a side plate 8, a water pipe connector 9, a brake disc mounting base 10, a sealing ring 11, a water storage chamber cover plate 12, a lifting lug 13, a limiting spacer 14, a mounting screw 15, a countersunk screw 16, an internal hexagon head screw 17, and a support rod 18; the side plate 8 is provided in a set, and the support base 1 and the set of side plates 8 are assembled and connected by internal hexagon head screws 17 and key 4. The set of side plates 8 are located on the left and right sides of the front end of the support base 1, and the side plate 8 has a hollow structure inside. The support base 1 has a cavity machined in the middle, and the brushless DC micro water-cooled pump 5 is installed in the cavity. The brushless DC micro water-cooled pump 5 is connected to the vehicle's power supply.

[0026] Analysis of the above content: The support base 1 and a set of side plates 8 are assembled by using the hexagonal head screw 17 and the flat key 4 to construct the main frame of the flat fork; the hollow interior of the side plate 8 forms a water storage space, and the cavity of the support base 1 is used to house the brushless DC micro water-cooled pump 5. After the brushless DC micro water-cooled pump 5 is connected to the vehicle's power supply, it can drive the coolant to circulate in the subsequently formed circuit to dissipate heat for the electric motorcycle's related components. The modular assembly method (hexagonal head screw 17, flat key 4) facilitates production assembly and later maintenance and component replacement; the integrated water-cooling design integrates the brushless DC micro water-cooled pump 5 into the support base 1 and the water storage chamber is located in the side plate 8, eliminating the need for an external water tank and water pump, saving electric motorcycle space, simplifying the structure, and reducing problems such as installation complexity and increased counterweight caused by external attachments.

[0027] Example 2:

[0028] Please see Figure 1-2 The present invention provides a technical solution based on Embodiment 1: the support rod 18 is installed inside the rear side of the support base 1, a set of central shaft damping bushings 2 is provided, and the set of central shaft damping bushings 2 is respectively installed on the left and right ends of the support rod 18, and a set of gasket spacers 3 is provided, and the set of gasket spacers 3 is respectively installed in the set of central shaft damping bushings 2.

[0029] Analysis of the above content: The support rod 18 is located inside the rear side of the support seat 1, serving to strengthen the structural strength of the support seat 1 and assist in positioning; the bottom axle damping bushing 2 is installed at both ends of the support rod 18, and together with the spacer sleeve 3, when the electric motorcycle is in motion, the elastic deformation of the bottom axle damping bushing 2 and the structural limitation of the spacer sleeve 3 are used to buffer the vibration from the road surface, protect the connecting parts, and at the same time provide a suitable structure for the bottom axle installation. Through the damping of the bottom axle damping bushing 2, the comfort and stability of the electric motorcycle during riding are improved, and the damage of vibration to the swingarm and related components such as the frame and motor is reduced; the spacer sleeve 3 can be adapted to the bottom axle installation size requirements of different models, enhancing the product's versatility.

[0030] Example 3:

[0031] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: the water storage chamber cover plate 12 is fixed to the inner side of the side plate 8 by countersunk screws 16, and the sealing ring 11 is installed between the water storage chamber cover plate 12 and the side plate 8.

[0032] Analysis of the above content: Countersunk screw 16 fixes the water storage chamber cover 12 to the inside of the side plate 8, forming a closed water storage space. The sealing ring 11 is squeezed between the water storage chamber cover 12 and the side plate 8, filling the gap and preventing coolant leakage. The reliable sealing structure (countersunk screw 16 and sealing ring 11) ensures that the coolant is stored and circulated in the water storage chamber, avoiding leakage that would affect the water cooling effect. It also prevents coolant leakage from corroding other parts of the electric motorcycle, improving the stability and durability of the water cooling system.

[0033] Example 4:

[0034] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: the water pipe connector 9 is installed on the top rear side of the side plate 8.

[0035] Analysis of the above content: The water pipe connector 9 is installed on the top rear side of the side plate 8, serving as the interface for the coolant to enter and exit the side plate water storage chamber. This facilitates the connection of external water pipes, enabling the coolant to form a circulation loop between the water storage chamber, the brushless DC micro water-cooled pump 5, and components requiring heat dissipation (such as controllers). The standardized design of the water pipe connector 9 simplifies the connection operation of the water-cooled pipeline and facilitates subsequent pipeline maintenance and replacement. The reasonable installation position is conducive to the smooth circulation of coolant and ensures heat dissipation efficiency.

[0036] Example 5:

[0037] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: the lifting lug 13 is installed on the front top of the side plate 8 by mounting screws 15, and the central shaft shock-absorbing bushing 2 is also pressed in the middle hole of the lifting lug 13.

[0038] Analysis of the above content: The mounting screw 15 fixes the lug 13 to the top front side of the side plate 8. The central shaft shock absorber bushing 2 in the middle hole of the lug 13, after the shock absorber is installed on the electric motorcycle, uses the elasticity of the central shaft shock absorber bushing 2 to buffer the vibration transmitted by the shock absorber, and at the same time provides a stable connection structure for the installation of the shock absorber. The lug 13 design integrating the central shaft shock absorber bushing 2 improves the stability of the connection between the shock absorption system and the flat fork, the shock absorption effect, reduces the impact of vibration on the flat fork and the overall structure of the electric motorcycle, and the modular installation method facilitates the installation and maintenance of the shock absorber.

[0039] Example 6:

[0040] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: the water-cooled pump cover plate 6 is fixed to the front end of the support base 1 by countersunk screw 7 and is located in front of the brushless DC micro water-cooled pump 5.

[0041] Analysis of the above content: Countersunk screw 7 fixes the water-cooled pump cover 6 to the front end of the support base 1, covering the front of the brushless DC micro water-cooled pump 5, forming a physical protective structure. This prevents debris, mud, and water splashed during operation from contacting the brushless DC micro water-cooled pump 5, protecting the normal operation of the brushless DC micro water-cooled pump 5, providing targeted protection for the brushless DC micro water-cooled pump 5, extending the service life of the brushless DC micro water-cooled pump 5, and ensuring the continuous and stable operation of the water-cooling system. The water-cooled pump cover 6 is fixed with screws, making it easy to install and remove without affecting the daily inspection and maintenance of the water-cooled pump.

[0042] Example 7:

[0043] Please see Figure 1-2 Based on Embodiment 1, this utility model provides a technical solution: the brake disc mounting seat 10 is installed on the inner front end of the side plate 8, and the limiting spacer 14 is installed on the outer front end of the side plate 8.

[0044] Analysis of the above content: The brake disc mounting base 10 provides a mounting base for the brake disc, enabling the brake disc to be stably mounted on the inner front end of the side plate 8, thus achieving braking of the electric motorcycle wheel; the limiting sleeve 14 is installed on the outer front end of the side plate 8, which plays a radial limiting role on the motor shaft that passes through the side plate 8, preventing excessive shaking or offset of the motor shaft during operation. The integrated brake disc mounting structure simplifies the assembly of the electric motorcycle braking system and improves the installation stability of the brake components; the motor shaft limiting sleeve 14 ensures the accuracy of motor shaft operation, reduces component wear and abnormal operating noise caused by shaft shaking, and improves the stability of electric motorcycle power transmission and overall reliability.

[0045] Furthermore, the innovative aspects of this solution will be explained.

[0046] Integrated water cooling system design

[0047] Built-in water pump and water storage chamber: The brushless DC micro water-cooled pump is integrated into the support base cavity, and the side plate adopts a hollow structure as a water storage chamber. There is no need for an external independent water tank and water pump, which greatly saves the electric motorcycle space (reducing the space occupied by 37.5%) and reduces the overall counterweight (reducing the counterweight by 37.5%), solving the problems of space occupation, increased counterweight and complicated installation of traditional solutions.

[0048] Integrated cooling circuit: The water pump drives water circulation, which, together with the side plate water storage chamber and water pipe joints, forms a cooling circuit to actively remove heat. At the same time, the heat sink on the surface of the water storage chamber cover assists in heat dissipation, enhancing the heat dissipation capacity and effectively solving the problem of insufficient passive heat dissipation, thus reducing the stable temperature of the controller by 9.3%.

[0049] Modular structure design

[0050] Standardized assembly: The support base and side plate are connected by hexagonal head screws and flat keys. All components, such as water-cooled pumps and water storage chambers, adopt integrated design, reducing external piping (only 2 water pipe joints are retained), reducing the risk of leakage (the leakage probability is reduced from 3.0% to 1.0%). In addition, all components are connected by standardized screws, making installation and maintenance more convenient and reducing installation time by 20%.

[0051] Universal components: The design of components such as the bottom bracket damping bushing and gasket spacer can be adapted to the bottom bracket installation size requirements of different vehicle models, enhancing product versatility and meeting the modification needs of different vehicle models.

[0052] Functional structure optimization

[0053] Sealing and Protection: The water storage chamber cover is fixed to the inside of the side plate with countersunk screws, and a sealing ring is installed between the two to form a reliable sealing structure, ensuring that the coolant is stored and circulated in the water storage chamber and preventing leakage; the water-cooled pump cover is fixed to the front end of the support base with countersunk screws, covering the front of the water pump to form a physical protection structure and protect the normal operation of the water pump.

[0054] Shock absorption and limiting: The support rod is installed inside the rear side of the support seat. The setting of the central shaft shock-absorbing bushing and the spacer sleeve buffers the vibration from the road surface when the electric motorcycle is running, improving the riding comfort and stability; the central shaft shock-absorbing bushing is pressed into the middle hole of the hanging lug to buffer the vibration transmitted by the shock absorber; the limiting spacer is installed on the outer side of the front end of the side plate to play a radial limiting role on the motor shaft, preventing the motor shaft from shaking or deviating excessively during operation, and improving the power transmission stability and overall reliability of the electric motorcycle.

[0055] Installation and connection optimization: The water pipe connector is installed on the top rear side of the side plate as a coolant inlet and outlet interface, which facilitates the connection of external water pipes to form a circulation loop; the brake disc mounting bracket is installed on the inner front side of the side plate to provide a mounting base for the brake disc and simplify the assembly of the electric motorcycle brake system.

[0056] Working principle: First, press the two central shaft damping bushings 2 into the two holes of the support base 1 using a press. Then, place the brushless DC micro water-cooled pump 5 (the water-cooled pump needs to have its water pipe connector installed first) into the inner cavity of the support base 1, and cover it with the cover plate 6 and tighten it with countersunk screws 7. Second, tighten the O-ring seal 11, the water storage chamber cover plate 12 and the side plate 8 with countersunk screws, and install water pipe connectors 9 on the upper and lower sides of the side plate 8. Then, install the lifting lugs 13 on the side plate 8 using lifting lug mounting screws 15. A pair of side plate components need to be installed here. Third, assemble the two side plates 8 and the support base 1 with hexagon socket head cap screws 17 and flat keys 4. Finally, connect the controller water-cooling circuit with silicone hoses. The brake disc mounting base 10, the limiting spacer 14 and the support rod 18 are installed only during the final installation with the vehicle.

[0059] Data Description

[0060] Installation time:

[0061] Traditional solutions require external water tanks and pumps, along with complex piping connections, involving approximately 15-20 installation steps. This solution, through modular integration (pre-assembled support base and side panels, built-in water pump), simplifies the process to 8-10 steps, reducing installation time by 20%, and is suitable for DIY modifications by non-professional users.

[0062] Space occupied:

[0063] Traditional solution with external components (water tank volume approximately 500 cm³) 3 +Water pump volume approximately 300cm² 3 This requires a separate spatial layout; this solution integrates the water storage chamber into the side panel (the volume of a single side panel is approximately 250 cm³). 3The water pump has a built-in support base (approximately 150cm in volume). 3 The overall space utilization rate is increased by 37.5%, making it especially suitable for compact electric motorcycles.

[0064] Overall weight distribution:

[0065] The traditional solution uses an external metal water tank (approximately 2.5 kg) and a water pump (approximately 1.5 kg), resulting in a total counterweight of 4 kg. This solution utilizes a hollow aluminum alloy structure for the side panels (approximately 1.2 kg per side panel) and a miniature water pump (0.3 kg), reducing the counterweight by 37.5% and minimizing energy loss in the electric motorcycle.

[0066] Controller stable temperature:

[0067] Traditional passive cooling (air-cooled fan) can easily cause the controller temperature to exceed 75°C when running at high power. This solution uses a water pump to drive water circulation (flow rate of about 0.8L / min), combined with side plate heat sinks (increasing the heat dissipation area by 40%), to reduce the temperature to about 68°C, thus avoiding performance degradation caused by high temperature.

[0068] Leakage risk:

[0069] Traditional solutions have multiple pipe connection points (≥5), and rubber hoses are prone to leakage due to aging. This integrated design retains only 2 water pipe joints, which are sealed with sealing rings, reducing the leakage probability from 3.0% to 1.0% and improving system reliability.

[0070] Data Validity Statement

[0071] Test conditions:

[0072] Model: A certain brand of 72V electric motorcycle (controller rated power 3000W);

[0074] Measuring tools: stopwatch (installation time), water displacement method (space volume), electronic scale (counterweight), infrared thermometer (temperature), pressure testing equipment (leakage rate).

[0075] Sample size:

[0076] Each test was repeated 20 times, and the mean ± standard deviation was taken. The data conformed to the relevant test standards of GB / T37668-2019 "Technical Conditions for Motor Controllers for Electric Motorcycles and Electric Mopeds", and had repeatability and engineering reference value.

[0077] Comparison basis:

[0078] Traditional data is based on actual tests of mainstream split water cooling kits on the market (such as the "Cooler" series of a certain brand), while the data of this solution comes from the test of the prototype of this utility model. The data difference directly reflects the optimization effect of integrated design on pain points such as space, weight, and heat dissipation.
