[0002] The automotive power supply is the core of the vehicle's electrical system, responsible for supplying power to various devices and stabilizing the voltage; the filter, as a key component, can effectively suppress electromagnetic interference and noise in the power supply; the two work together to ensure the safe and stable operation of on-board electronic equipment.

[0003] A power supply filter is a filtering circuit composed of capacitors, inductors, and resistors. Also known as a "power EMI filter" or "EMI power filter," it is a passive bidirectional network with one end connected to the power supply and the other to the load. Power supply filters can effectively filter out specific frequencies or frequencies outside of the power supply line.

[0004] When a power filter is in use, dust can fall into the power socket when it comes into contact with the external environment, and prolonged dust accumulation can cause damage.

[0005] Therefore, an automotive power filter is proposed to address the above problems. Utility Model Content

At the same time, the baffles are designed for easy removal after installing the protective shells, reducing the need for operation of the protective shells and accelerating the auxiliary operation of the car power filter body.

[0008] Preferably, a pair of spring telescopic rods are fixedly connected inside the clamping plate; a compression plate is fixedly connected to the end of each spring telescopic rod; the bottom of the compression plate is sloped; by adding the spring telescopic rods and the compression plate, the spring telescopic rods can be compressed by the thrust generated by the compression when the clamping plate contacts the automotive power filter body. Then, the compression force generated by the spring telescopic rods is used to push the compression plate out and make it fit tightly against the automotive power filter body. This increases stability when installing the protective shell. At the same time, the sloped bottom of the compression plate can reduce the downward pressure resistance when inserted into the automotive power filter body, allowing it to move down quickly.

[0009] Preferably, a plug is fixedly connected to the bottom of the baffle; the bottom of the plug is arc-shaped; the plug and the outlet and inlet are correspondingly arranged and slidably engaged; by adding the plug, the outlet and inlet can be closed when the wire is pulled out of the outlet and inlet, thereby sealing the outlet and inlet inside after the protective shell is closed during use, and the arc shape at the bottom of the plug allows it to move down more smoothly when in contact with the outlet and inlet.

[0010] Preferably, a handle is fixedly connected to the top of the placement slot; the handle and the placement slot are correspondingly arranged; by adding a handle, the baffle can be quickly lifted and pressed down when operating the baffle, thereby increasing the gripping area during operation and speeding up the operation of the baffle.

[0011] Preferably, a friction pad is fixed to the inner wall of the extrusion plate; multiple friction pads are provided on the extrusion plate; by increasing the number of friction pads, the contact area can be increased through compression deformation to generate excess frictional resistance, thereby increasing the stability after installation.

[0013] The advantages of this utility model are:

[0014] 1. The automotive power filter of this utility model, by adding a protective shell and a baffle, can block dust from the surrounding environment when protecting the power outlet and power inlet, thereby reducing the contact area between dust and the power outlet and power inlet during operation.

[0015] 2. The automotive power filter described in this utility model, by adding a spring telescopic rod and a compression plate, can compress the spring telescopic rod by the thrust generated by the compression when the clamping plate and the automotive power filter body come into contact.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the figure, an automotive power filter according to an embodiment of the present invention includes an automotive power filter body 1, with an outlet 11 and an inlet 12 sequentially arranged at the end of the automotive power filter body 1; a pair of protective shells 13 are provided on the surface of the automotive power filter body 1; the protective shells 13 and the outlet 11 and inlet 12 are correspondingly arranged; a pair of clamping plates 16 are fixedly connected to the bottom of the protective shells 13; the clamping plates 16 and the automotive power filter body 1 are in sliding fit; a placement groove 1 is opened in the middle of the protective shells 13. 4; A baffle 15 is slidably fitted inside the placement slot 14; A pair of locking blocks 17 are fixedly connected to the inner wall of one side of the protective shell 13; The ends of the locking blocks 17 are trapezoidal; A pair of locking slots 18 are opened inside the other side of the protective shell 13; The locking blocks 17 and the locking slots 18 are correspondingly arranged and slidably fitted; During operation, the wires are connected through the power outlet 11 and the power inlet 12, and then after being powered on, the pins, capacitors, etc. on it are used to perform signal cancellation. This is a mature existing technology and will not be described in detail here. In use, the baffles 15 on the pair of protective shells 13 can be removed to leave a space in the middle. Then, the clamp 16 is inserted into the car power filter body 1 and engaged. After engagement, the pair of protective shells 13 are pushed towards the middle to connect the locking block 17 and the locking slot 18, thereby increasing the contact in the middle and increasing the stability during fixation. After the work is finished, the wires are pulled out and the baffles 15 can be placed inside the placement slot 14. At this time, the power outlet 11 and the power inlet 12 will be closed, forming a closed space. The baffle 15 is designed to block dust from the surrounding environment, thereby reducing the impact on wiring during operation when the baffle 15 is removed. By adding the protective shell 13 and the baffle 15, the dust in the surrounding environment can be blocked while protecting the power outlet 11 and the power inlet 12, thus reducing the contact area between dust and the power outlet 11 and the power inlet 12 during operation. At the same time, the baffle 15 is designed to be easy to remove after the protective shell 13 is installed, thus reducing the operation of the protective shell 13 and speeding up the auxiliary operation of the automotive power filter body 1.

[0026] like Figure 4As shown, a pair of spring telescopic rods 2 are fixedly connected inside the clamping plate 16; a pressing plate 21 is fixedly connected to the end of the spring telescopic rod 2; the bottom of the pressing plate 21 is set with an incline; during operation, when the clamping plate 16 and the car power filter body 1 are brought into contact, the pressing plate 21 will first contact the car power filter body 1, and the car power filter body 1 will then contact the pressing plate 21. The spring telescopic rod 21 will move on the surface of the extrusion plate 21. Then, the extrusion plate 21 will be pushed by the force generated when it is pressed down, so that it applies pressure to the spring telescopic rod 2 and compresses it. When the clamping plate 16 is installed, the thrust generated by the compression of the spring telescopic rod 2 will push the extrusion plate 21 out and make it fit tightly against the car power filter body 1, thereby increasing the clamping effect when installing the protective shell 13. By adding the spring telescopic rod 2 and the extrusion plate 21, the spring telescopic rod 2 can be compressed by the thrust generated by the extrusion when the clamping plate 16 and the car power filter body 1 come into contact. Then, the extrusion plate 21 is pushed out and made to fit tightly against the car power filter body 1 by the force generated by the compression of the spring telescopic rod 2, thereby increasing the stability when installing the protective shell 13. At the same time, the slope at the bottom of the extrusion plate 21 can reduce the downward pressure resistance when it is inserted into the car power filter body 1, so that it moves down quickly.

[0027] like Figures 2 to 5 As shown, a plug rod 3 is fixedly connected to the bottom of the baffle 15; the bottom of the plug rod 3 is arc-shaped; the plug rod 3 and the outlet 11 and inlet 12 are correspondingly arranged and slidably engaged; during operation, when the baffle 15 is installed after the automotive power filter body 1 has finished working, the plug rod 3 can be inserted into the outlet 11 and inlet 12 to seal the outlet 11 and inlet 12. At the same time, when inserted into the outlet 11, it can also guide the downward movement of the baffle 15 during installation; by adding the plug rod 3, when the wire is pulled out from the outlet 11 and inlet 12, the outlet 11 and inlet 12 can be closed by the plug rod 3. Thus, during use, the outlet 11 and inlet 12 are sealed inside after the protective shell 13 is closed. At the same time, the arc shape at the bottom of the plug rod 3 can make the downward movement smoother when it comes into contact with the outlet 11 and inlet 12.

[0028] like Figures 1 to 4 As shown, a handle 4 is fixedly connected to the top of the placement slot 14; the handle 4 and the placement slot 14 are correspondingly arranged; during operation, the handle 4 can contact the baffle 15 when it is disassembled or installed, and the baffle 15 can be operated by the handle 4 after contact, thereby speeding up the operation of the baffle 15; by adding the handle 4, the baffle 15 can be quickly lifted and pressed down when operating the baffle 15, thereby increasing the gripping area during operation and speeding up the operation of the baffle 15.

[0029] like Figure 4As shown, a friction pad 5 is fixed to the inner wall of the extrusion plate 21; multiple friction pads 5 are arranged on the extrusion plate 21; during operation, when the extrusion plate 21 contacts the automotive power filter body 1, the friction pad 5 will deform under the thrust, and after deformation, the contact area with the automotive power filter body 1 will increase, thereby increasing the frictional resistance during movement; by increasing the friction pad 5, the contact area can be increased through pressure deformation to generate excess frictional resistance, thereby increasing the stability after installation.

[0030] like Figures 1 to 3 As shown, a hook 6 is fixedly connected to the side wall of the protective shell 13; the hook 6 and the protective shell 13 are correspondingly arranged; during operation, after the baffle 15 is removed, the handle 4 can be placed on the hook 6, so that the handle 4 can be hung up through the hook 6. When the handle 4 is hung up, the baffle 15 can be placed and stored; by adding the hook 6, the baffle 15 can be quickly stored by the handle 4 after it is removed and stays on the protective shell 13. When closing, the baffle 15 can be quickly removed and closed, thereby increasing convenience.

[0031] Working principle: When the wires are connected through the power outlet 11 and the power inlet 12, the device operates by utilizing its own pins, capacitors, etc., to perform signal cancellation. This is a mature existing technology and will not be elaborated here. During use, the baffles 15 on the pair of protective shells 13 can be removed to leave a central space. Then, the clamp 16 is inserted into the automotive power filter body 1 for engagement. After engagement, the pair of protective shells 13 are pushed towards the center to connect the locking block 17 and the locking slot 18, thereby increasing the central contact and enhancing stability during fixation. After the operation is completed, the wires are pulled out, and the baffle 15 can be placed inside the placement slot 14. This closes the power outlet 11 and the power inlet 12, forming a closed space to block surrounding dust. Thus, removing the baffle 15 during operation reduces the impact on wiring. When the clamp 16 contacts the automotive power filter body 1, the pressing plate 21 will first contact the automotive power filter body 1. Upon contact, the automotive power filter body 1... The clamping plate 21 will move on the surface of the extrusion plate 21. The extrusion plate 21 will then be pushed by the force generated during downward pressure, compressing the spring telescopic rod 2. When the clamping plate 16 is installed, the thrust generated by the compression of the spring telescopic rod 2 will push the extrusion plate 21 out and tightly adhere it to the automotive power filter body 1, thus increasing the clamping effect when installing the protective shell 13. When installing the baffle 15 after the automotive power filter body 1 has finished working, the insert rod 3 can be inserted into the outlet port 11 and inlet port 12 to seal them. Simultaneously, when inserted into the outlet port 11, it can also seal the baffle 15. The downward movement during installation increases guidance; when the baffle 15 is disassembled and installed, it can contact the handle 4. After contact, the baffle 15 can be operated by moving the handle 4, thereby speeding up the operation of the baffle 15; when the extrusion plate 21 contacts the automotive power filter body 1, the friction pad 5 will deform under the thrust, and after deformation, it will increase the contact area with the automotive power filter body 1, thereby increasing the frictional resistance during movement; after the baffle 15 is removed, the handle 4 can be placed on the hook 6, so that the handle 4 can be hung up by the hook 6. After the handle 4 is hung up, the baffle 15 can be placed as a whole for storage.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
