Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle accessories, and particularly relates to an anti-interference electric vehicle controller. Background Art

[0002] The electric vehicle controller is one of the core control components of an electric vehicle. It is responsible for controlling actions such as starting, accelerating, decelerating, braking, and steering of the electric vehicle. The electric vehicle controller usually consists of a microprocessor, sensors, actuators, a power management module, a drive circuit, etc. Through these components, the controller can receive operation signals from the driver, such as the accelerator pedal, brake pedal, steering wheel, etc., and convert them into control signals for the motor to drive the motor of the electric vehicle to work, thereby realizing the movement of the vehicle.

[0003] The electronic components inside the electric vehicle controller are very sensitive to electromagnetic interference. Electromagnetic interference may cause the performance of the components to decline or even be damaged. Therefore, anti-interference settings are often required to protect these components from the influence of interference and extend their service life. The traditional anti-interference setting method is often to directly set an electromagnetic shielding cover outside the controller. The traditional electromagnetic shielding cover and the controller are often connected by threads. This connection method is very inconvenient when the controller fails and needs to be taken out. In addition, once the threads are rusted, it is very difficult to take out the controller without damaging the electromagnetic shielding cover.

[0004] In view of this, an anti-interference electric vehicle controller is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the connection method between the electromagnetic shielding cover and the controller of the traditional anti-interference electric vehicle controller needs to be improved, and to provide an anti-interference electric vehicle controller.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme: an anti-interference electric vehicle controller, including a controller main body and two first sliders with an inverted T-shaped cross-section fixedly connected to the bottom of the controller main body. A shielding cover is sleeved on the controller main body. Two first chutes adapted to the first sliders are opened on the shielding cover. The bottom of the shielding cover is elastically connected with a mounting seat through a plurality of first springs. A plurality of mounting blocks are slidably arranged on the mounting seat. A cover plate for limiting the controller main body is detachably mounted on the shielding cover. Two insertion rods are fixedly connected to the cover plate. Insertion holes adapted to the two insertion rods are opened on the shielding cover. A locking groove is opened in the insertion hole. A locking block adapted to the locking groove for locking the insertion rod is arranged on the insertion rod.

[0007] Further, a plurality of second springs are fixedly connected to the inner wall surface of the cavity of the shielding cover. One ends of the plurality of second springs are fixedly connected to the shielding cover, and the other ends of the plurality of second springs are commonly fixedly connected to a buffer plate.

[0008] Further, second sliders with a T-shaped cross-section are fixedly connected to both sides of the mounting block. Second chutes adapted to the size of the second sliders are formed in the mounting seat, and mounting holes are formed in the mounting block.

[0009] Further, the end of the locking block away from the cover plate is inclined, and the locking block and the insertion rod are elastically connected by a plurality of third springs.

[0010] Further, two symmetrically arranged unlocking rods are provided on the shielding cover. The unlocking rods are elastically connected to the shielding cover through fourth springs. Unlocking holes for inserting the unlocking rods are formed in the shielding cover, and the unlocking holes are located in the locking grooves.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. In the anti-interference electric vehicle controller provided by the present utility model, through the settings of the locking block and the unlocking rod, the connection between the controller and the shielding cover is made more tight and more convenient to disassemble;

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-8 .

[0027] The anti-interference electric vehicle controller of the present utility model includes a controller main body 1 and two first sliders 2 with an inverted T-shaped cross-section fixedly connected to the bottom of the controller main body 1. A shielding cover 3 is sleeved on the controller main body 1. Two first chutes 4 adapted to the first sliders 2 are provided on the shielding cover 3. The bottom of the shielding cover 3 is elastically connected with a mounting seat 5 through a plurality of first springs 6. A plurality of mounting blocks 9 are slidably arranged on the mounting seat 5. A cover plate 14 for limiting the controller main body 1 is detachably mounted on the shielding cover 3. Two plug rods 15 are fixedly connected to the cover plate 14. A jack 13 adapted to the two plug rods 15 is provided on the shielding cover 3. A locking groove 17 is provided in the jack 13. A locking block 16 adapted to the locking groove 17 for locking the plug rod 15 is provided on the plug rod 15.

[0028] In addition, a plurality of second springs 8 are fixedly connected to the inner wall surface of the cavity of the shielding cover 3. One end of the plurality of second springs 8 is fixedly connected to the shielding cover 3, and the other ends of the plurality of second springs 8 are commonly fixedly connected to a buffer plate 7. When specifically arranged, after the controller main body 1 is inserted into the shielding cover 3, it should exactly squeeze the second spring 8 connected to the buffer plate 7. Subsequently, when the cover plate 14 is locked, the second spring 8 should be in a decompressed state.

[0029] Wherein, both sides of the mounting block 9 are fixedly connected with second sliders 11 having a T-shaped cross-section. Second chutes 12 adapted to the size of the second sliders 11 are formed on the mounting seat 5. Mounting holes 10 are formed on the mounting block 9. During installation, since the mounting block 9 can slide, the device can meet more installation requirements, that is, the installation position of the mounting block 9 can be adjusted, so the application range of the device is wider.

[0030] In addition, one end of the locking block 16 away from the cover plate 14 is provided with an inclined surface, and the locking block 16 and the insertion rod 15 are elastically connected through a plurality of third springs 18. That is to say, when the insertion rod 15 is inserted into the insertion hole 13, the insertion hole 13 will squeeze the locking block 16 and compress the third spring 18. Until the insertion rod 15 is inserted to the limit position, that is, when the locking block 16 moves to the locking groove 17, the insertion hole 13 no longer squeezes the locking block 16 and the third spring 18. At this time, the locking block 16 pops out under the action of the third spring 18 and just locks with the locking groove 17, completing the connection between the cover plate 14 and the shielding cover 3. At the same time, the cover plate 14 also tightly covers the first slider 2 at the bottom of the controller body to prevent it from separating from the shielding cover 3.

[0031] Secondly, two symmetrically arranged unlocking rods 20 are provided on the shielding cover 3. The unlocking rods 20 are elastically connected to the shielding cover 3 through fourth springs 21. Unlocking holes 19 for inserting the unlocking rods 20 are formed on the shielding cover 3. The unlocking holes 19 are located in the locking grooves 17, as Figure 4 shown. Since the unlocking holes 19 are located in the locking grooves 17 and the unlocking rods 20 are located in the unlocking holes 19, when the unlocking rods 20 are pressed, the unlocking rods 20 squeeze the locking block 16 and the third spring 18 in the locking grooves 17 through the unlocking holes 19. At this time, since the locking block 16 is no longer limited by the locking groove 17, the cover plate 14 can be directly removed.

[0032] It should be noted that the arrangement of multiple first springs 6 can buffer the impact on the controller body 1 and the shielding cover 3 in the vertical direction, and the arrangement of multiple second springs 8 can buffer the impact on the controller body 1 in the horizontal direction. Therefore, the impacts on the controller body 1 from multiple directions during use can all be buffered, which can improve the stability of the working environment of the controller body 1 to a certain extent and prevent problems such as the disconnection of interfaces. In addition, the arrangement of the cover plate 14 makes the switching between the locked state and the unlocked state of the connection between the controller body and the shielding cover 3 more convenient, greatly improving the convenience of disassembly and assembly of the device.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes that fall within the meaning and scope of the equivalent elements of the claims in the present utility model.
