Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycle parts, in particular to a waterproof insulation box structure of an electric motorcycle. Background Art

[0002] At present, with the increasing popularity of new energy vehicles, fuel motorcycles are gradually being replaced by electric motorcycles in the motorcycle field. The most common method is to use oil-to-electricity conversion, removing the engine, cylinder, etc. of the fuel motorcycle and using lithium batteries and motors to drive the electric motorcycle. In the driving mode of the electric motorcycle, some electronic components need to be added to achieve this, such as controllers, high-voltage lines, air switches, etc. These electronic components are generally directly installed on the frame. In the existing technology, these controllers have their own controller shells to achieve a certain degree of protection, and the air switches are also matched with air switch shells for protection. However, in actual use, the use of traditional shell structures to install these electronic components has some problems that need to be solved, as follows: (1) In the existing technology, electronic components such as controllers and air switches are directly installed on the frame bracket of the electric motorcycle. When the electric motorcycle is used in rainy days, rainwater will directly enter these electronic components (the outer shell of the electronic controller itself is not sealed enough). After the electric motorcycle was tested with water, it was found that the electronic components also had water ingress. Such a protection method can easily cause a short circuit in the circuit system of the electric motorcycle. (2) The outer shells of the electric control components in the prior art are generally square. Once water enters (without touching the corresponding circuit), the water will remain and accumulate in the shell and cannot be discharged in time, which will greatly increase the risk of short circuits in the subsequent circuit system. (3) In response to the defects of the outer shells of the electric control components in the prior art, some people have also designed and developed some protective shells to seal and install these electric control components to achieve the corresponding waterproof function. Although these protective shells achieve a certain waterproof effect, the overly sealed structure cannot timely discharge the heat generated by the operation of the electric control components, resulting in an increase in the temperature of the electric control components, affecting the heat dissipation effect of the electric control components, causing the performance of the electric control components to decline and shortening their service life, seriously affecting the driving performance and safety of the electric motorcycle.

[0003] Therefore, it is necessary to make certain improvements to the protective structure of the electric motorcycle installed with these electrical controls in the prior art to improve the problems of the prior art, and to develop a waterproof insulation box structure for protecting the installed electrical controls and improving the waterproof insulation performance without affecting the heat dissipation effect. Summary of the Invention

[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a waterproof insulation box structure for an electric motorcycle. The waterproof insulation box structure of the electric motorcycle adopts a waterproof insulation box with sealed top and side parts, a controller and an air switch installed from the bottom, and a waterproof insulation box cover installed in cooperation with the bottom of the waterproof insulation box to form a certain drainage structure. After the controller and the air switch are installed in the waterproof insulation box, they are at a certain height from the bottom of the waterproof insulation box to prevent water from being easily contaminated due to poor sealing in extreme cases. At the same time, a heat dissipation port is also provided on the waterproof insulation box cover to ensure the heat dissipation effect. Such a structure effectively blocks the contact between water and important electrical components without affecting the heat dissipation of the electrical components, more effectively protects the circuit system, makes the electric motorcycle safer and prolongs the driving life.

[0033] Example 1

[0034] The waterproof insulation box structure of an electric motorcycle described in this embodiment 1 is as follows: Figure 1 and Figure 2As shown, it includes a waterproof insulation box 2 installed in a vehicle frame 1, a controller 3 and an air switch 4 installed in the waterproof insulation box from the bottom of the waterproof insulation box, and a waterproof insulation box cover 5 fixedly mounted to and covering the bottom of the waterproof insulation box. The waterproof insulation box structure consists of two major components: the waterproof insulation box and the waterproof insulation box cover. The top and outer sides of the waterproof insulation box are both integrated seamless sealing structures. The controller and air switch are installed from the waterproof insulation box bottom box. The waterproof insulation box cover covers the bottom of the waterproof insulation box to form a good sealing and waterproof structure. It prevents rainwater from pouring onto the waterproof insulation box structure from the bottom to the top, and still maintains an excellent waterproof effect. The entire waterproof insulation box structure is installed in a relatively deep position in the vehicle frame, providing a certain degree of protection and water isolation.

[0035] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the waterproof insulation box is provided with a controller mounting slot (not shown) for mounting a controller and an air switch mounting slot (not shown) for mounting an air switch. The controller mounting slot 6 and the air switch mounting slot 7 of the controller mounting slot are both facing downward. The top and outer sides of the waterproof insulation box are sealed. During installation, the controller is installed from the controller mounting slot upwards into the controller mounting slot and into place, and the air switch is installed from the air switch mounting slot upwards into the air switch mounting slot and into place. The controller mounting slot and the air switch mounting slot are both facing downwards to prevent water from entering and accumulating in the corresponding mounting slots. Even if water enters the mounting slots, it can be promptly drained downwards without soaking the corresponding electrical components.

[0036] like Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 As shown, the waterproof insulation box cover is provided with a U-shaped opening 8 for heat dissipation, which corresponds to the controller mounting notch. This U-shaped opening is used to dissipate heat from the controller, improving heat dissipation. The U-shaped opening is located at a certain distance from the controller and is not directly opposite it, ensuring heat dissipation while minimizing water resistance and keeping it away from water sources. Furthermore, when the entire waterproof insulation box structure is installed within the vehicle frame, the U-shaped opening is located relatively deep within the frame, providing a certain waterproof barrier to the U-shaped opening, increasing waterproof protection and enhancing water-blocking capabilities.

[0037] In this first embodiment, the bottom of the waterproof insulation box is provided with an outward-turned insulation box skirt 9. The center of the insulation box skirt is a horizontally disposed horizontal skirt, and the left and right sides of the insulation box skirt are upwardly inclined inclined skirts. The center of the waterproof insulation box cover is a horizontally disposed flat plate corresponding to the horizontal skirt, and the left and right sides of the waterproof insulation box cover are upwardly inclined plates corresponding to the inclined skirt. The irregular shape of the insulation box skirt and the inclined skirts on both sides facilitate downward drainage, preventing accumulated water from entering the waterproof insulation box. The shape of the waterproof insulation box cover, when installed in conjunction with the insulation box skirt, provides a good seal and guides water for drainage.

[0038] In this first embodiment, the outer surface of the waterproof insulation box is provided with a locking opening 10 located above the skirt of the insulation box; the outer edge of the waterproof insulation box cover is provided with a locking head 11 that protrudes upward and snaps into the locking opening to form a locking fit. When the waterproof insulation box and the waterproof insulation box cover are assembled, the locking opening and the locking head form a quick and easy locking installation, which ensures a secure and convenient installation. During the locking installation, the waterproof insulation box cover and the three sides of the waterproof insulation box are locked together.

[0039] In this first embodiment, the outer surface of the waterproof insulation box is further provided with an insulation box mounting hole 12 located above the insulation box skirt. The outer side of the waterproof insulation box cover is further provided with an upwardly protruding insulation box cover mounting bracket 13 that is mounted correspondingly to the insulation box mounting hole. The insulation box cover mounting bracket is provided with an insulation box cover mounting hole 14 that is mounted correspondingly to the insulation box mounting hole. The insulation box mounting hole and the insulation box cover mounting hole are fixed together by screws. The other side of the waterproof insulation box and the waterproof insulation box cover are fixed together by screws through the insulation box mounting hole and the insulation box cover mounting hole. During installation, the insulation box cover mounting bracket is inserted into the inner wall of the waterproof insulation box. Once in place, the insulation box mounting hole and the insulation box cover mounting hole are aligned. The two holes can then be screwed together to secure the waterproof insulation box and the waterproof insulation box cover on this side.

[0040] In this embodiment 1, the controller mounting slot and the air switch mounting slot are both gradually narrowed from bottom to top, and the controller and the air switch are respectively installed in the controller mounting slot and the air switch mounting slot to form a clamped and fixed installation. By designing the groove cavity of the controller mounting slot and the air switch mounting slot to be gradually narrowed, when the controller and the air switch are installed in place, the interference fit of the groove cavity can be used to form a clamped and fixed installation for the relevant components. Moreover, after the controller and the air switch are installed in place, there is a certain height distance between them and the waterproof insulation box cover, that is, the bottom of the controller and the air switch will not be very close to the waterproof insulation box cover. In this way, if the waterproof insulation box cover leaks, the controller will not get wet. In addition, the design of the insulation box skirt and the shape design of the waterproof insulation box cover can also drain water in time, ensuring that the controller and the air switch are kept away from water sources as much as possible.

[0041] In this embodiment 1, the waterproof insulation box is provided with insulation box fixing holes 15 on both outer sides thereof, which are matched with the vehicle frame. These insulation box fixing holes secure the entire waterproof insulation box structure to the vehicle frame. After installation, these insulation box fixing holes are sealed with a waterproof material or with a plugging cover to ensure that these holes also meet a certain waterproof level.

[0042] In this embodiment 1, the waterproof insulation box further includes an air switch mounting slot threading hole 16 that communicates with the air switch mounting slot. This threading hole allows for connection of the air switch and the connection between the air switch and the controller. After connection is complete, the threading hole is also waterproofed and sealed in the same manner as the aforementioned fixed mounting hole of the insulation box.

[0043] In this first embodiment, the top of the waterproof insulation box is further provided with a controller mounting slot see-through cover 17 and an air switch mounting slot see-through cover 18, which respectively provide visibility into the controller mounting slot and the air switch mounting slot. These two covers form an integrally connected waterproof seal with the top of the waterproof insulation box. These covers are integrally formed with the top of the waterproof insulation box, providing a virtually seamless and excellent sealing performance. These covers provide a visual indication of the functional status and performance of the controller and air switch, and can also indicate whether the corresponding components require repair or replacement without removing the waterproof insulation box structure from the vehicle frame.

[0044] In this embodiment 1, the waterproof insulation box structure of the electric motorcycle adopts a waterproof insulation box with sealed top and sides, a controller and air switch installed from the bottom, and a waterproof insulation box cover installed in conjunction with the bottom of the waterproof insulation box to form a certain drainage structure. After the controller and the air switch are installed in the waterproof insulation box, they are at a certain height from the bottom of the waterproof insulation box to prevent water from being easily contaminated due to poor sealing in extreme cases; at the same time, heat dissipation vents are also provided on the waterproof insulation box cover to ensure heat dissipation effect; such a structure effectively blocks the contact between water and important electrical components without affecting the heat dissipation of the electrical components, more effectively protecting the circuit system, making the electric motorcycle safer and extending the driving life.

[0045] The above description is only a preferred embodiment of the present invention and does not constitute any formal limitation on the structure of the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
