Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to an anti-electromagnetic interference shielding shell structure based on a new energy vehicle motor controller. Background Technology

[0002] The motor controller of a new energy vehicle is the core component of the drive system, equivalent to the "power brain" of the vehicle. Its function is to convert the DC power from the battery into the AC power required by the motor, and to precisely control the motor's speed, torque and operating status.

[0003] Existing motor controllers lack internal electromagnetic shielding structures when used in processing areas, making them susceptible to external electromagnetic interference during operation. Furthermore, the controllers require bolts for assembly, reducing assembly efficiency and ease of maintenance. Therefore, this invention proposes an anti-electromagnetic interference shielding shell structure for new energy vehicle motor controllers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an anti-electromagnetic interference shielding housing structure based on a new energy vehicle motor controller. By setting a metal shield inside the controller housing, it can shield external electromagnetic interference, thereby enabling the motor controller to work stably. The housing is designed as a cover, which can be quickly installed and fixed by a snap-fit ​​structure. At the same time, a positioning and reinforcement component is added to improve the protection strength of the entire controller housing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an anti-electromagnetic interference shielding shell structure based on a new energy vehicle motor controller, including a mounting base, a protective shell being snapped onto the top of the mounting base, a metal shielding layer being snapped onto the inner wall of the protective shell, an exhaust fan being bolted to the top of the mounting base near one side, a snap-fit ​​structure being symmetrically fixed to the top of the mounting base near the side wall, and a reinforcement component being installed at the top of the mounting base near one corner.

[0006] The present invention is further configured such that: connecting blocks are fixedly connected to the corners of the outer wall of the mounting base; multiple through grooves A are symmetrically opened on the top of the mounting base near the end face; and through grooves B are symmetrically opened on the side wall of the mounting base near the middle.

[0007] The above technical solution allows the connecting block to fix the entire mounting base in place, and through slots A and B to quickly dissipate the high temperature generated inside.

[0008] The present invention is further configured such that: the protective shell is made of multi-layer composite shielding material, the outer layer of which is a conductive metal layer and the inner layer is an insulating heat dissipation layer.

[0009] The above technical solution facilitates the use of a protective shell to further increase the protection against external electromagnetic interference and improve the protection strength.

[0010] The present invention is further configured such that: a fixing groove is symmetrically provided at the bottom of the protective shell near the end face; a fixing block is symmetrically fixedly connected to the outer wall of the metal shielding layer near the end face; and multiple fixing blocks are respectively embedded in multiple corresponding fixing grooves.

[0011] The above technical solution facilitates the use of a metal shielding layer to resist external electromagnetic interference, and uses fixing blocks to fix it inside the protective shell.

[0012] The present invention is further configured such that: the buckle structure includes a buckle seat installed on the top of the mounting base, a U-shaped component is provided on the top of the buckle seat, a buckle block is fixedly connected to the middle of the side wall of the U-shaped component, and the buckle block is engaged with a buckle groove opened near the bottom of the end face of the protective shell, and a bending pressing part is provided at the bottom of the U-shaped component.

[0013] The above technical solution utilizes an elastic U-shaped component, which allows the side wall's locking block to be stably embedded in the slot after being squeezed, thereby achieving the locking and fixing of the protective shell. Furthermore, the pressing part can be used to press the U-shaped component, facilitating the disassembly of the protective shell.

[0014] The present invention is further configured such that: the reinforcing component includes a pin for sliding connection mounting base, the outer wall of the pin is wrapped with a spring, a stop block is fixedly connected to the outer wall of the pin near the end face, the end face of the pin is inserted into a positioning block fixedly set at the bottom of the protective shell near the corner, and a pull block is fixedly connected to the end face of the pin.

[0015] The above technical solution utilizes a pull block to slide the pin, thereby causing the stop block to compress the spring. Then, when the positioning block is inserted into the predetermined position, the pull block is released, and the elasticity of the compressed spring causes the stop block to drive the pin to insert into the positioning block, thus fixing the protective shell.

[0016] The present invention is further configured such that the two ends of the spring abut against the mounting base and the stop block, respectively.

[0017] The above technical solution facilitates the rapid return of the spring after it is subjected to pressure, allowing the pin to be inserted into the positioning block.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figures 1-5As shown, the electromagnetic interference shielding housing structure based on the motor controller of a new energy vehicle includes a mounting base 1. Connecting blocks 11 are fixedly connected to the corners of the outer wall of the mounting base 1. Multiple through slots A12 are symmetrically opened on the top of the mounting base 1 near its end face, and through slots B13 are symmetrically opened on the side wall of the mounting base 1 near its center. The connecting blocks 11 can fix the entire mounting base 1 in position, and the through slots A12 and B13 can quickly dissipate the high temperature generated inside. A protective shell 2 is snapped onto the top of the mounting base 1. The protective shell 2 is made of multi-layer composite shielding material, with its outer layer being conductive metal. The inner layer is an insulating and heat dissipation layer, which facilitates the use of the protective shell 2 to further increase the resistance to external electromagnetic interference and improve the protection strength. The inner wall of the protective shell 2 is fitted with a metal shielding layer 3. The bottom of the protective shell 2 is symmetrically provided with fixing grooves 21 near the end face. The outer wall of the metal shielding layer 3 is symmetrically fixedly connected with fixing blocks 31 near the end face. Multiple fixing blocks 31 are embedded in multiple corresponding fixing grooves 21, which facilitates the use of the metal shielding layer 3 to resist external electromagnetic interference and to fix it inside the protective shell 2 using fixing blocks 31. The top of the mounting base 1 is bolted to one side with an exhaust fan 4.

[0030] like Figure 4 and Figure 6 As shown, a snap-fit ​​structure 5 is symmetrically fixedly connected to the top of the mounting base 1 near the side wall. The snap-fit ​​structure 5 includes a snap-fit ​​seat 51 installed on the top of the mounting base 1. A U-shaped part 52 is provided on the top of the snap-fit ​​seat 51. A snap-fit ​​block 53 is fixedly connected to the middle of the side wall of the U-shaped part 52. The snap-fit ​​block 53 is engaged with a slot 22 opened near the bottom of the end face of the protective shell 2. A bending pressing part 54 is provided at the bottom of the U-shaped part 52. Using the elastic U-shaped part 52, the snap-fit ​​block 53 on the side wall can be stably embedded in the slot 22 after being squeezed, thereby achieving the snap-fit ​​fixation of the protective shell 2. The pressing part 54 can be used to press the U-shaped part 52 to facilitate the disassembly of the protective shell 2. A reinforcing component 6 is installed on the top of the mounting base 1 near one corner. The reinforcing component 6 includes a sliding connection installation. The pin 61 of the base 1 has a spring 62 wrapped around its outer wall. The two ends of the spring 62 abut against the mounting base 1 and the stop block 63 respectively, so that the spring 62 can quickly return to its original position after being pressed, allowing the pin 61 to be inserted into the positioning block 23. The stop block 63 is fixedly connected to the outer wall of the pin 61 near its end face. The end face of the pin 61 is inserted into the positioning block 23 fixedly set near the corner of the bottom of the protective shell 2. The end face of the pin 61 is fixedly connected to the pull block 64. The pull block 64 is used to pull the pin 61 to slide, thereby causing the stop block 63 to compress the spring 62. Then, when the positioning block 23 is inserted into the predetermined position, the pull block 64 is released. The elasticity of the compressed spring 62 causes the stop block 63 to drive the pin 61 to be inserted into the positioning block 23, thereby fixing the protective shell 2.

[0031] In use, the metal shielding layer 3 is first fixed inside the protective shell 2 using the fixing block 31. Then, the pin 61 is slid by pulling the pull block 64, which causes the stop block 63 to compress the spring 62 and keeps the pull block 64 fixed to the side wall of the mounting base 1. Next, the protective shell 2 is pressed into the inside of the two buckle structures 5. Using the elastic U-shaped part 52, the buckle 53 on the side wall can be stably embedded in the buckle groove 22 after being compressed, thereby realizing the snap-fit ​​fixation of the protective shell 2. Finally, the pull block 64 is moved to use the elasticity of the spring 62 after compression, so that the stop block 63 drives the pin 61 to insert into the positioning block 23, thereby fixing the protective shell 2.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
