[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The electric vehicle controller 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 3 As shown, the electric vehicle controller 100 according to an embodiment of the present invention includes a housing 1, an electronic control component 2, and a plastic-coated housing 3.

[0041] Specifically, such as Figure 1 and Figure 3 As shown, the shell 1 is non-annular and includes a first sidewall 11 and a second sidewall 12. One end of the first sidewall 11 in the width direction and one end of the second sidewall 12 in the width direction are connected. The first sidewall 11 and the second sidewall 12 form an angle with each other and together define an included angle space. The angle between the first sidewall 11 and the second sidewall 12 can be an obtuse angle, a right angle, or an acute angle. The space within the included angle formed by the first sidewall 11 and the second sidewall 12 is the included angle space. For example, in... Figure 1 and Figure 3 In the example shown, the angle between the first sidewall 11 and the second sidewall 12 is a right angle, and the included space formed between the first sidewall 11 and the second sidewall 12 is a right angle space.

[0042] like Figure 1 and Figure 3 As shown, the electronic control component 2 is located within the included space. The electronic control component 2 can be used to control the starting, running, forward and reverse movement, speed, and stopping of the electric vehicle 1000 motor, as well as other electronic components of the electric vehicle 1000. The housing 1 can position and protect the electronic control component 2.

[0043] like Figure 1 and Figure 3 As shown, the plastic-coated shell 3 fills the space within the included angle, excluding the electronic control component 2, and is used to cover the exposed portion of the electronic control component 2. That is, the exposed portion of the electronic control component 2 is wrapped with plastic to form an integral structure. The plastic-coated shell 3 and the housing 1 together protect the electronic control component 2, ensuring the reliability of its operation, thereby ensuring the reliability of the electric vehicle controller 100. Furthermore, the plastic-coated shell 3 filling the space within the included angle, excluding the electronic control component 2, allows for connection between the plastic-coated shell 3 and the electronic control component 2 and the housing 1 without the need for screws or other fasteners, achieving the technical effects of optimizing the process, improving production efficiency, and reducing costs.

[0044] In related technologies, electric vehicles typically employ an aluminum shell with end caps. The aluminum shell is annular, with an end cap at each axial end to seal the open openings. The end caps and the aluminum shell are connected by fasteners, and a sealant is used between them for sealing. This process is cumbersome, inefficient, and costly. In this application, the shell 1 is non-annular and includes a first sidewall 11 and a second sidewall 12 at an angle to each other (it can be understood that the shell 1 in this application can be a portion of the aluminum shell structure in related technologies). The end caps and fastening structures such as screws at both ends of the shell 1 are eliminated. A plastic-coated shell 3 is filled within the space between the first sidewall 11 and the second sidewall 12. This achieves the technical effects of optimizing the process, improving production efficiency, and reducing costs while simultaneously securing and protecting the electronic control components 2.

[0045] According to an embodiment of the present invention, the electric vehicle controller 100, by setting the housing 1 to be non-circular and including a first sidewall 11 and a second sidewall 12 that are connected to each other and at an angle, and the electronic control component 2 is disposed in the included angle space formed between the first sidewall 11 and the second sidewall 12, and the plastic shell 3 fills the included angle space except for the part of the electronic control component 2, not only is the positioning and protection of the electronic control component 2 achieved, but also the end caps and screws and other fastening components can be eliminated, thereby achieving the technical effects of optimizing the process, improving production efficiency and reducing costs.

[0046] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, at least one of the first sidewall 11 and the second sidewall 12 has a groove 15 on the side facing the included space, and the plastic-coated shell 3 has a protrusion 31 that mates with the groove 15. This improves the reliability of the connection between the first sidewall 11 or the second sidewall 12 and the plastic-coated shell 3, ensuring the effectiveness of fixing and protecting the electronic control component 2.

[0047] Of course, in other embodiments of the present invention, at least one of the first sidewall 11 and the second sidewall 12 has a protrusion 31 on the side facing the included angle space, and the plastic-coated shell 3 has a groove 15 that mates with the protrusion 31. This can improve the reliability of the connection between the first sidewall 11 or the second sidewall 12 and the plastic-coated shell 3, and ensure the effect of fixing and protecting the electronic control component 2.

[0048] For example, in Figure 1In the example shown, the end of the first sidewall 11 facing away from the second sidewall 12 and towards the included angle space is provided with a groove 15, and the end of the second sidewall 12 facing away from the first sidewall 11 and towards the included angle space is also provided with a groove 15. The plastic-coated shell 3 is provided with multiple protrusions 31 that mate with the multiple grooves 15. This increases the reliability of the connection between the first sidewall 11 and the second sidewall 12 and the plastic-coated shell 3. Furthermore, the width of the groove 15 gradually decreases from the bottom wall of the groove 15 to the opening of the groove 15, thereby preventing the protrusions 31 on the plastic-coated shell 3 from detaching from the groove 15, further ensuring the reliability of the connection between the plastic-coated shell 3 and the first sidewall 11, as well as between the plastic-coated shell 3 and the second sidewall 12.

[0049] Furthermore, one of the opposite side walls of the groove 15 is inclined toward the other side wall in the direction from the bottom wall of the groove 15 to the opening. Of course, the invention is not limited to this, and both opposite side walls of the groove 15 may be inclined toward each other in the direction from the bottom wall of the groove 15 to the opening.

[0050] For example, in Figure 3 In the example shown, a groove 15 is provided on the side of the first sidewall 11 facing away from the second sidewall 12 and toward the included space, and a protrusion 31 that mates with the groove 15 is provided on the plastic-coated shell 3. This increases the reliability of the connection between the first sidewall 11 and the plastic-coated shell 3. Specifically, the width of the groove 15 gradually decreases in the direction from the bottom wall to the opening of the groove 15. One of the opposite sidewalls of the groove 15 is inclined toward the other sidewall in the direction from the bottom wall to the opening of the groove 15. Of course, the invention is not limited to this; both opposite sidewalls of the groove 15 can be inclined toward each other in the direction from the bottom wall to the opening of the groove 15. This prevents the protrusion 31 on the plastic-coated shell 3 from detaching from the groove 15, further ensuring the reliability of the connection between the plastic-coated shell 3 and the first sidewall 11, as well as between the plastic-coated shell 3 and the second sidewall 12.

[0051] In addition, the second sidewall 12 is also provided with a groove 15 on the side of the angled space near the first sidewall 11. The inner contour of the groove 15 is U-shaped, which makes it easy for the plastic shell 3 to be filled into the groove 15.

[0052] In some embodiments of the present invention, the electric vehicle controller 100 is a single unit. This eliminates the need for the interconnection process between the housing 1, the electronic control component 2, and the plastic-coated housing 3, thereby improving production efficiency and reducing production costs.

[0053] Optionally, the electric vehicle controller 100 is formed as a single unit using injection molding or compression molding. Both injection molding and compression molding utilize a mold, where the housing 1 and the electronic control components 2 are pre-placed within the mold, and finally, the plastic-coated shell 3 is formed through injection molding or compression molding. This simplifies the manufacturing process of the electric vehicle controller 100, ensures the reliability of the connection between the housing 1, the electronic control components 2, and the plastic-coated shell 3, further optimizes the process, improves production efficiency, and reduces costs.

[0054] When the plastic-coated shell 3 is molded using injection molding, a low-pressure injection method is employed to prevent damage to the components inside or on the electronic control assembly 2 from being blown away when the raw material for the plastic-coated shell 3 is poured into the mold. This also prevents the electronic control assembly 2 from shifting within the included space, ensuring the reliability and integrity of the electronic control assembly 2. Alternatively, when the plastic-coated shell 3 is manufactured using compression molding, it can be formed using molded rubber. Both injection molding and compression molding methods can produce various shapes as needed.

[0055] Alternatively, the positioning structure of the positioning electronic control component 2 may not be provided on the shell 1. Instead, the positioning structure of the positioning electronic control component 2 may be provided inside the mold. The electronic control component 2 is positioned by the mold, and then the plastic shell 3 is formed.

[0056] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the second sidewall 12 has a mounting plane 121 on the side facing the included angle space. The mounting plane 121 can be parallel to the width direction of the second sidewall 12. The electronic control assembly 2 includes an electronic control board 21 and a MOSFET (Metal Oxide Semiconductor Field Effect Transistor). One surface of the electronic control board 21 in the thickness direction is disposed opposite to the first sidewall 11. The electronic control board 21 can be disposed parallel to the width direction of the first sidewall 11. The MOSFET 22 is located on the side of the electronic control board 21 facing away from or away from the first sidewall 11 and is connected to the electronic control board 21. The MOSFET 22 is attached to the mounting plane 121. During the operation of the electronic control assembly 2, heat is generated, and the MOSFET 22 also generates heat. Attaching the MOSFET 22 to the mounting plane 121 better achieves the fit between the MOSFET 22 and the mounting plane 121, thereby allowing the MOSFET 22 to dissipate heat better through the housing 1.

[0057] In addition, the plastic-coated shell 3 fills the included space and completely covers the electronic control board 21 and MOSFET 22. The heat generated by the electronic control board 21 and MOSFET 22 can also be dissipated through the plastic-coated shell 3, which improves the heat dissipation effect of the electric vehicle controller 100 and helps to reduce costs.

[0058] In related technologies, electric vehicle controllers employ an aluminum housing with end caps, forming a closed mounting cavity. The electronic control components are housed within this cavity, which is filled with thermal adhesive. Heat from the electronic control components is transferred to the thermal adhesive and then to the housing and end caps for dissipation, or directly to the aluminum housing and end caps. Existing technologies involve pouring large amounts of thermal adhesive, resulting in high costs and complex processes. This application, however, eliminates the need for thermal adhesive pouring compared to existing technologies, optimizing the process, improving production efficiency, and reducing costs.

[0059] Furthermore, such as Figure 1 and Figure 3 As shown, a heat dissipation pad 4 is provided between the MOSFET 22 and the mounting plane 121. This allows for seamless contact between the MOSFET 22, the heat dissipation pad 4, and the housing 1, effectively dissipating heat. It should be noted that the areas of the mounting plane 121 and the heat dissipation pad 4 can be designed according to the heat dissipation requirements of the MOSFET 22.

[0060] Optionally, the heat dissipation pad 4 is a thermally conductive silicone component. The thermally conductive silicone is easily deformable and can be effectively adsorbed onto uneven curved surfaces, better fitting with the housing 1 and the MOSFET 22, thereby achieving a better heat dissipation effect for the MOSFET 22.

[0061] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the electric vehicle controller 100 also includes a spring 5, which is disposed in the included angle space and is used to press the MOSFET 22 onto the mounting plane 121. This allows the MOSFET 22 and the mounting plane 121 to fit better, ensuring a seamless fit between the MOSFET 22 and the mounting plane 121 on the housing 1, thus guaranteeing the heat dissipation effect of the MOSFET 22.

[0062] Furthermore, such as Figure 1 and Figure 3 As shown, a slot 122 is provided on the second sidewall 12. The slot 122 is located on the side of the mounting plane 121 opposite to the control board 21, which facilitates the placement of the slot 122. Additionally, a spring clip 5 is attached to the housing 1 and includes a first piece 51 and a second piece 52. One end of the first piece 51 and one end of the second piece 52 are connected and form an angle with each other. The connection between the first piece 51 and the second piece 52 is smoothly transitioned. The end of the first piece 51 opposite to the second piece 52 is inserted into the slot 122, and the end of the second piece 52 opposite to the first piece 51 abuts against the side of the MOSFET 22 opposite to the mounting plane 121. Thus, the elastic force between the first piece 51 and the second piece 52 can hold the MOSFET 22 against the mounting plane 121, ensuring effective heat dissipation for the MOSFET 22.

[0063] The space in the slot 122 excluding the first piece 51 can be filled with the plastic-coated shell 3, thereby improving the reliability of the connection between the plastic-coated shell 3 and the second sidewall 12.

[0064] Optionally, such as Figure 1 and Figure 3 As shown, the slot 122 is recessed along the width direction of the first sidewall 11. The sidewall of the slot 122 near the control board 21 has a first guide slope 1221, which is located at the open end of the slot 122. In the direction from the bottom wall of the slot 122 to the open opening, the first guide slope 1221 is inclined towards the control board 21 to guide the insertion of the first piece 51 into the slot 122. The sidewall of the slot 122 away from the control board 21 has a second guide slope 1222, which is located at one end of the slot 122 near the bottom wall. In the direction from the open opening of the slot 122 to the bottom wall, the second guide slope 1222 is inclined towards the control board 21 to guide the insertion of the first piece 51 and also enhance the structural strength of the first sidewall 11.

[0065] In some embodiments of the present invention, the angle between the first plate 51 and the second plate 52 is less than or equal to 90 degrees, thereby enhancing the elastic force between the first plate 51 and the second plate 52. When the first plate 51 is inserted into the slot 122, the pressure applied by the second plate 52 to the MOS transistor 22 is enhanced, thereby ensuring the clamping effect on the MOS transistor 22, ensuring the fit between the MOS transistor 22 and the housing 1, and thus ensuring the heat dissipation effect of the MOS transistor 22.

[0066] exist Figure 1 In the example shown, the housing 1 includes only a first sidewall 11 and a second sidewall 12. The housing 1 is L-shaped. The MOSFET 22 is located on the side of the control board 21 facing the first sidewall 11. A latching protrusion 16 is provided on the sidewall of the first sidewall 11 facing the included angle space. The connection between the first piece 51 and the second piece 52 is engaged with the latching protrusion 16 on the side facing the second sidewall 12. The latching protrusion 16 restricts the movement of the spring piece 5 away from the second sidewall 12. The engagement of the slot 122 and the first piece 51 further restricts the movement of the spring piece 5 away from the first sidewall 11, thereby improving the fixing effect of the spring piece 5. This allows the second piece 52 to abut against the side of the MOSFET 22 away from the mounting plane 121, ensuring the pressing effect on the MOSFET 22, ensuring the fit between the MOSFET 22 and the housing 1, and thus ensuring the heat dissipation effect of the MOSFET 22.

[0067] Among them, the surface of the protrusion 16 facing the second side wall 12 is inclined in the direction away from the second side wall 12 in the direction facing the electronic control board 21 and is an arc-shaped surface that is concave in the direction away from the second side wall 12.

[0068] exist Figure 3 In the example shown, the housing 1 also includes a third sidewall 13. One end of the third sidewall 13 in the width direction is connected to the end of the second sidewall 12 away from the first sidewall 11 and forms an angle with the second sidewall 12. The third sidewall 13 and the first sidewall 11 are located on the same side of the second sidewall 12, and the included angle space is located between the first sidewall 11 and the third sidewall 13. The housing 1 is formed in a semi-I-shape. The MOS transistor 22 is disposed on the side of the control board 21 away from the first sidewall 11. A latching protrusion 16 is provided on the sidewall of the third sidewall 13 facing the included angle space. The connection between the first plate 51 and the second plate 52 is latched onto the side of the latching protrusion 16 facing the second sidewall 12. The protrusion 16 restricts the movement of the spring piece 5 away from the second sidewall 12. The cooperation between the slot 122 and the first plate 51 restricts the movement of the spring piece 5 away from the first sidewall 11, thereby improving the fixing effect of the spring piece 5. This allows the second plate 52 to abut against the side of the MOS transistor 22 away from the mounting plane 121, thus ensuring the pressing effect on the MOS transistor 22, ensuring the fit between the MOS transistor 22 and the housing 1, and thus ensuring the heat dissipation effect of the MOS transistor 22.

[0069] Among them, the surface of the protrusion 16 facing the second side wall 12 is inclined in the direction away from the second side wall 12 in the direction facing the electronic control board 21 and is an arc-shaped surface that is concave in the direction away from the second side wall 12.

[0070] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the width of the third sidewall 13 is smaller than the width of the first sidewall 11. This allows the width of the third sidewall 13 to be minimized while facilitating the setting of the protrusion 16. The extended position of the third sidewall 13 can be filled with the plastic-coated shell 3, which facilitates the filling of the plastic-coated shell 3.

[0071] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the width direction of the first sidewall 11 is perpendicular to the width direction of the second sidewall 12, the width direction of the third sidewall 13 is perpendicular to the width direction of the second sidewall 12, and the width direction of the third sidewall 13 is the same as the width direction of the first sidewall 11. This allows the housing 1 to be formed as part of a rectangular housing 1, which simplifies the processing technology and production cost of the housing 1.

[0072] In some embodiments of the present invention, such as Figure 1 and Figure 3As shown, a limiting groove 123 is provided on the side of the second sidewall 12 facing the included angle space, and one end of the electronic control board 21 in the width direction is located in the limiting groove 123. This can improve the reliability of positioning the electronic control board 21, ensure the reliability of the operation of the electronic control component 2, and ensure the reliability of fixing the MOSFET 22, further ensuring the heat dissipation effect of the MOSFET 22. In addition, it can also ensure that the electronic control board 21 does not shift during the processing of the plastic shell 3.

[0073] exist Figure 1 In the example shown, the housing 1 includes only a first sidewall 11 and a second sidewall 12.
