Description

Technical Field

[0001] This utility model relates to a water pump assembly structure, and more particularly to a water pump assembly structure suitable for a water-cooled motor. Background Technology

[0002] In recent years, with the stringent environmental regulations and energy crisis in various countries around the world, electric vehicles are gradually replacing internal combustion engine vehicles to reduce exhaust pollution.

[0003] However, because electric motorcycles are significantly more expensive than internal combustion engine motorcycles, they typically employ more affordable design features, prioritizing air-cooled motors for power. Please see [link / reference]. Figure 1 This is a perspective view of an existing electric motorcycle with an air-cooled motor. As shown, the existing electric motorcycle 90 uses an air-cooled motor 91 to drive the rear wheel 912, and the battery 93 of the electric motorcycle 90 adopts a swappable, high-capacity design to reduce the purchase price of the electric motorcycle 90. The air-cooled motor 91 uses a cooling fan 92 to help dissipate heat to the outside; however, due to its limited heat dissipation capacity, the air-cooled motor 91 cannot effectively provide continuous long-distance travel.

[0004] Driven by this, and in the spirit of active invention, the inventor sought a water pump assembly structure that could solve the above problems. After several research and experiments, he finally completed this utility model. Utility Model Content

[0005] The main purpose of this utility model is to provide a water pump assembly structure that adopts a side-mounted cooler water-cooled motor design, which is different from the previous front-mounted cooler air-cooled motor design. The water-cooled motor can solve the problem of poor heat dissipation efficiency of the past air-cooled motor, achieving a high-efficiency motor. By placing the cooler on the side of the water-cooled motor, the water pump assembly structure is made more compact, effectively providing a larger storage space for large-capacity batteries.

[0006] To achieve the above objectives, this utility model provides a water pump assembly structure mounted on the frame of an electric motorcycle. It includes a water-cooled motor, a coolant tank, an electronic water pump, a cooler, a first coolant pipe, a second coolant pipe, and a third coolant pipe. The water-cooled motor, mounted on the frame, includes a motor inlet, a motor outlet, and a water-cooled motor body, used to drive the rear wheel. The coolant tank includes a tank inlet, a tank outlet, and a tank body, used to store cooled coolant. The electronic water pump includes a pump inlet, a pump outlet, and a pump body. The pump body is mounted on the coolant tank body, and the pump inlet is fitted over the tank outlet, used to pump coolant. The cooler includes a cooler inlet, a cooler outlet, and a cooler body, disposed on the side of the water-cooled motor, used to cool the coolant. The two ends of the first cooling water pipe are connected to the cooler outlet and the liquid tank inlet, respectively. The two ends of the second cooling water pipe are connected to the water pump outlet and the motor inlet, respectively. The two ends of the third cooling water pipe are connected to the motor outlet and the cooler inlet, respectively.

[0007] Through the above design, this utility model effectively shortens the cooling water path and mechanical space by placing the cooler on the side of the water-cooled motor. Compared with the existing front-cooled configuration, it is less likely for foreign objects to get stuck in front, and the cooling effect and maintainability are better. In addition, electric motorcycles with water-cooled motors can effectively provide continuous long-distance driving due to their better heat dissipation capacity.

[0008] The frame may include a head tube, a main tube, a bottom tube and a tail tube connected in sequence.

[0009] From a side view of the electric motorcycle, the water-cooled motor, coolant tank, and electric water pump can be configured in the area surrounded by the bottom tube extension line and the tail tube.

[0010] Viewed from the side by the electric motorcycle, the cooler can be positioned below the extension line of the bottom tube.

[0011] The aforementioned electronic water pump may include a temperature sensor and a pulse width modulator.

[0012] The above overview and the following detailed description are illustrative in nature and are intended to further illustrate the scope of the present invention. Other objects and advantages of the present invention will be described in the subsequent detailed embodiments and accompanying drawings. Attached Figure Description

[0050] Please see Figure 2 and Figure 3 These figures are a side view and a perspective view of a water pump assembly structure of an electric motorcycle with a water-cooled motor, respectively, according to a preferred embodiment of the present invention. The figures show a water pump assembly structure 1 mounted on a frame 11 of an electric motorcycle 10. In this embodiment, the frame 11 includes a head pipe 111, a main pipe 112, a bottom pipe 113, and a tail pipe 114 connected in sequence. The water pump assembly structure 1 includes a water-cooled motor 2, a coolant tank 3, an electric water pump 4, a cooler 5, a first cooling water pipe 6, a second cooling water pipe 7, and a third cooling water pipe 8. The water-cooled motor 2, mounted on the frame 11, includes a motor inlet 21, a motor outlet 22, and a water-cooled motor body 23, used to drive a rear wheel 12 to rotate. The coolant tank 3 includes a tank inlet 31, a tank outlet 32, and a tank body 33, used to store cooled coolant. The electric water pump 4 includes a water pump inlet 41, a water pump outlet 42, a water pump body 43, a temperature sensor (not shown), and a pulse width modulator (PWM) (not shown). The water pump body 43 is mounted on the coolant tank body 33, and the water pump inlet 41 is fitted onto the coolant tank outlet 32 ​​for pumping coolant. The temperature sensor senses changes in the operating temperature of the water-cooled motor 2, and the PWM automatically adjusts the speed and timing of the water pump body 43. From a side view of the electric motorcycle 10, the water-cooled motor 2, coolant tank 3, and electric water pump 4 are located within the area enclosed by a bottom pipe extension line L of the bottom pipe 113 and the tail pipe 114. The cooler 5 includes a cooler inlet 51, a cooler outlet 52, and a cooler body 53. The cooler 5 is located on the side of the water-cooled motor 2 and below the bottom pipe extension line L. The two ends of the first cooling water pipe 6 are connected to the cooler outlet 52 and the liquid tank inlet 31, respectively. The two ends of the second cooling water pipe 7 are connected to the water pump outlet 42 and the motor inlet 21, respectively. The two ends of the third cooling water pipe 8 are connected to the motor outlet 22 and the cooler inlet 51, respectively.

[0051] The operation of the water pump assembly structure 1 is as follows: When the electric motorcycle 10 is in a cold state, the coolant flows from the coolant tank 3 to the electronic water pump 4. However, since the water-cooled motor 2 has not yet reached its operating temperature, the water pump body 43 will not rotate, allowing the temperature of the water-cooled motor 2 to be quickly increased, achieving energy saving. Conversely, when the electric motorcycle 10 is in a hot state, the coolant flows from the coolant tank 3 to the electronic water pump 4. Since the water-cooled motor 2 has reached its operating temperature, the water pump body 43 will rotate and pump the coolant into the water-cooled motor 2 through the second cooling water pipe 7. Then, the coolant flows to the cooler 5 through the third cooling water pipe 8 for cooling, and then flows back to the coolant tank 3 through the first cooling water pipe 6 for storage. This continuous water circulation effectively controls the temperature of the water-cooled motor 2 within a specific range, ensuring an extended lifespan for the water-cooled motor 2. The water pump assembly structure 1 automatically controls the speed of the electronic water pump 4 based on the temperature sensor on the water-cooled motor 2, thereby controlling the flow rate of the coolant, and then the temperature is reduced by the cooler 5.

[0052] Through the above design, the water pump assembly structure of this utility model adopts a side-mounted cooler water-cooled motor design, which is different from the previous front-mounted cooler air-cooled motor design. The water-cooled motor can solve the problem of poor heat dissipation efficiency of the past air-cooled motor, and achieve a high-efficiency motor. By placing the cooler on the side of the water-cooled motor, the space of the water pump assembly structure is made more compact, effectively providing a larger storage space for large-capacity batteries.

[0053] The above embodiments are merely illustrative examples for ease of explanation. The scope of the rights claimed by this utility model should be determined by the scope of protection claimed in the patent application documents, and not limited to the above embodiments.
