Main component modular water-cooled electric scooter

Abstract

This utility model discloses a modular water-cooled electric scooter with a main component, including a footplate shell, a water pump, a circulating pipe that can circulate and seal the water pump, and a semiconductor cooling chip for cooling the circulating pipe. Coolant flows inside the circulating pipe. A mounting part is provided at the front end of the footplate shell, and a fan that drives the rotation is installed at the mounting part. The air outlet of the fan is connected to an airflow pipe. The diameter of the airflow pipe gradually increases, with the smaller diameter end connected to the fan outlet, and the larger diameter end facing the circulating pipe and spaced apart. Compared with the prior art, the advantages of this utility model are that the airflow pipe can concentrate and evenly diffuse airflow. While using the airflow pipe for heat dissipation, the even airflow from the larger diameter end of the airflow pipe results in lower air temperature, and the blown air can effectively cover the surface of components requiring heat dissipation, thus facilitating heat dissipation.

Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, and specifically to a modular water-cooled electric scooter with a main component. Background Technology

[0002] An electric scooter is a modern mode of transportation that is powered by electricity, using components such as motors and batteries to provide power, enabling the scooter to travel on roads.

[0003] For example, the patent with authorization announcement number CN116443151B provides a water-cooled electric scooter, which includes a water pump, an external circulation pipe, a semiconductor cooling chip, a heat dissipation pipe, and a cooling fan. The external circulation pipe is connected to the water pump and the semiconductor cooling chip, and the external circulation pipe is connected to the heat dissipation pipe, which is connected to the cooling fan. The cooling fan can cool the heat dissipation pipe.

[0004] The cooling fan works in conjunction with the water cooling system to cool components such as the battery and controller. However, the cooling fan blows air directly out of the heat dissipation pipes, which makes the airflow from the cooling fan relatively dispersed. Furthermore, the direct airflow from the cooling fan can easily create local high pressure in the air outlet area, hindering the smooth flow of air and thus limiting the cooling effect of the cooling fan on the heat dissipation pipes. Utility Model Content

[0005] This invention addresses the problem that the direct airflow from the cooling fan in existing electric scooters results in limited cooling effect on the cooling pipes. The technical problem this invention aims to solve is to provide a modular water-cooled electric scooter with a main component that can improve the cooling effect of the fan.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a modular water-cooled electric scooter with a main component, including a pedal shell with a battery or controller installed inside, a water pump fixedly connected to the pedal shell, a circulation pipe distributed around the battery or controller and capable of circulating and sealing the water pump, and a semiconductor cooling chip in the circulation pipe for cooling effect, with coolant flowing in the circulation pipe. The front end of the pedal housing is provided with a mounting part, and a fan that drives the rotation is installed at the mounting part. The air outlet of the fan is connected to an air circulation pipe. The diameter of the air circulation pipe is set from small to large. The small diameter end of the air circulation pipe is connected to the air outlet of the fan, while the large diameter end of the air circulation pipe faces the circulation pipe and is spaced apart.

[0007] A further preferred embodiment of this utility model is that the mounting portion on the pedal shell is tilted backward, and the air circulation pipe is obliquely arranged in the direction of airflow from the circulation pipe.

[0008] A further preferred embodiment of this utility model is: the fan includes a first fixing member and a second fixing member clamped and fixed on the mounting part, a fan blade is rotatably mounted between the first fixing member and the second fixing member, and the second fixing member is located inside the pedal shell.

[0009] A further preferred embodiment of this utility model is: the fan blade is provided with a rotation auxiliary part, and a rolling element for assisting the rotation of the fan blade is provided between the rotation auxiliary part and the fixing part one or the fixing part two.

[0010] A further preferred embodiment of this utility model is: a limiting groove is provided on the first or second fixing member, and the rolling member is disposed between the limiting groove and the rotation auxiliary part, with the limiting groove guiding the rotation direction of the rolling member.

[0011] A further preferred embodiment of this utility model is that the rolling element includes needle rollers or balls.

[0012] A further preferred embodiment of this utility model is: the second fixing member is provided with a first connecting section, and the air circulation pipe is provided with a second connecting section that is threadedly connected to the first connecting section.

[0013] A further preferred embodiment of this utility model is: the front end of the pedal shell is provided with a connecting part, the connecting part is located between two mounting parts, and the mounting part and the connecting part form an angle greater than 90° and less than 180°.

[0014] A further preferred embodiment of this utility model is: a cover is movably installed on the connecting part or the mounting part, and the cover can shield or avoid the air inlet of the fan.

[0015] Compared with the prior art, the advantages of this utility model are that by setting the fan away from the battery, controller and circulation pipe, an air circulation pipe with an ever-increasing diameter can be installed on the fan and directed towards the battery, controller and circulation pipe. The setting of the air circulation pipe can guide and integrate the air blown out by the fan, making the airflow more concentrated. Under the diffusion and guidance effect of the ever-increasing diameter of the air circulation pipe, the airflow is evenly diffused to a larger area of ​​the air circulation pipe. While using the air circulation pipe for heat dissipation, the uniform airflow from the large diameter of the air circulation pipe results in lower air temperature, and the blown air can effectively cover the surface of the components that need heat dissipation, thus making it more conducive to heat dissipation of the battery, controller and circulation pipe.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] This embodiment mainly describes the modular water-cooled electric scooter with a main component that improves fan cooling performance, as detailed below: like Figure 1-8 As shown, the main component modular water-cooled electric scooter includes a footboard shell 1, a water pump 2 fixedly installed inside the footboard shell 1, a closed circulation pipe 3 connected to the water pump 2, coolant flowing inside the circulation pipe 3, and the water pump 2 driving the coolant to flow inside the circulation pipe 3. A semiconductor cooling chip 4 is connected to the circulation pipe 3, and the semiconductor cooling chip 4 can cool the coolant through the circulation pipe 3. A fan 5 is installed at the front end of the footboard shell 1, and an air circulation pipe 6 is connected to the air outlet of the fan 5. The air circulation pipe 6 faces the location of the circulation pipe 3. Preferably, a battery or controller is installed in the footboard shell 1 (the battery and controller are not shown in the attached drawings of the specification), and the circulation pipe 3 is distributed around the battery or controller.

[0022] In this embodiment, the air circulation pipe 6 is provided with an expansion section 61 whose diameter gradually increases. The large-diameter end of the expansion section 61 is close to the circulation pipe 3 and spaced apart, so that the air blown out by the fan 5 is guided and integrated, making the airflow more concentrated. Under the diffusion guidance effect of the small-to-large diameter of the air circulation pipe 6, the airflow is evenly diffused to a larger area of ​​the air circulation pipe 6. While using the air circulation pipe 6 for heat dissipation, the large-diameter part of the air circulation pipe 6 is used to evenly blow out air, making the temperature of the blown air lower. The blown air can effectively cover the surface of the components that need heat dissipation, thus making it more conducive to heat dissipation of the battery, controller and circulation pipe 3.

[0023] like Figure 2-5 As shown, the front end of the pedal housing 1 is provided with a connecting part 11 and mounting parts 12 located on both sides of the connecting part 11. The mounting parts 12 are arranged obliquely to the rear, and the angle between the mounting parts 12 and the connecting part 11 facing rearward is greater than 90° and less than 180°. The fan 5 is fixed on the mounting part 12.

[0024] By fixing the fan 5 on the mounting part 12, when the air blown out by the fan 5 flows through the air guide pipe, the air flowing out of the air guide pipe contacts the circulation pipe 3 at an angle, which increases the contact area between the air and the circulation pipe 3 and improves the heat dissipation efficiency.

[0025] In this embodiment, the fan 5 is driven to rotate by the wind force when riding the electric scooter. The fan 5 is fixed on the mounting part 12 to facilitate the side rotation of the fan 5 by the wind.

[0026] like Figure 3-7As shown, the fan 5 includes a first fixing member 5a, a second fixing member 5b, a fan blade 5c, and a rolling member 5d. In this embodiment, the second fixing member 5b is disposed inside the pedal housing 1. The mounting portion 12 of the pedal housing 1 has a mounting hole 13, and the second fixing member 5b has an insertion section 5b1 that inserts into the mounting hole 13. The insertion section 5b1 has a tubular structure, and one end of the insertion section 5b1 has an outer limiting portion 5b2 that fits against the inner wall of the pedal housing 1. The first fixing member 5a fits against the outer wall of the pedal housing 1 and is fixedly connected to the insertion section 5b1 of the second fixing member 5b by multiple screws. The inner wall of the insertion section 5b1 has a protruding part. The inner limiting part 5b3 and the fixing part 5a are in the form of a ring structure. The inner diameter of the fixing part 5a is smaller than the inner diameter of the mounting hole 13 and the insertion section 5b1. A receiving groove 51 is formed between the inner limiting parts 5b3 of the fixing part 5a and the fixing part 5b. The fan blade 5c is rotatably installed in the inner ring of the fixing part 5a and the fixing part 5b. Each blade of the fan blade 5c is provided with a rotating auxiliary part 5c1 that is inserted into the receiving groove 51. The rolling part 5d is located in the receiving groove 51 and is rotatably installed between the receiving groove 51 and the rotating auxiliary part 5c1. The rotating auxiliary part 5c1 and the rolling part 5d are in contact with each other on their arc surfaces.

[0027] Preferably, the outer dimensions of the first fixing member 5a and the outer limiting part 5b2 are larger than the inner diameter of the mounting hole 13, and the first fixing member 5a and the second fixing member 5b are clamped together to fix the mounting part 12.

[0028] In this embodiment, the rolling element 5d is a ball bearing or a ball bearing. The position of the rolling element 5d changes as the fan blade 5c rotates. In order to prevent the rolling element 5d from moving out of the rotation auxiliary part 5c1 in the receiving groove 51, a limiting groove 5b4 is provided in the inner ring of the insertion section 5b1 of the fixing part 2 5b, that is, the bottom of the receiving groove 51. The limiting groove 5b4 guides the rotation direction of the rolling element 5d.

[0029] In other embodiments, the outer ring of the blade of the fan blade 5c may also be provided with an annular closed outer ring, and the rolling element 5d is disposed between the outer ring and the insertion section 5b1.

[0030] To prevent the fan 5 from rotating in the mounting hole 13, the outer wall of the insertion section 5b1 of the second fixing member 5b can be in planar contact or concave-convex fit with the inner wall of the mounting hole 13; or the screw that fixes the first fixing member 5a and the second fixing member 5b passes through the mounting part 12, and the screw connects the outer limiting part 5b2 of the first fixing member 5a and the second fixing member 5b.

[0031] The outer limiting part 5b2 is provided with a protruding connecting section 5b5, and the air circulation pipe 6 is provided with a connecting section 62. The connecting section 5b5 and the connecting section 62 are threadedly connected. The connecting section 62 can abut against the outer limiting part 5b2 to restrict rotation. The connecting section 62 on the air circulation pipe 6 is connected to the small diameter end of the expansion section 61.

[0032] like Figure 1 , Figure 6 and 8 As shown, a cover 7 is magnetically connected to the fixing part 5a. The cover 7 can shield or avoid the air intake end of the fan 5, restricting the fan blades 5c of the fan 5 from rotating in the wind when riding the electric scooter. This ensures that the fan 5 does not affect the use of the battery when riding the electric scooter in low temperatures. The cover 7 can also be detached from the fixing part 5a and attached to the connecting part 11 of the pedal shell 1 for later use.

[0033] In other embodiments, the cover 7 may also be rotatably or slidably installed.
