During vehicle operation, the automotive circuit boards are responsible for processing and transmitting various electronic signals, enabling precise control of critical systems such as the engine, brakes, and steering.

[0003] Existing automotive circuit boards lack adequate overall protection. As vehicles experience various complex road conditions during operation, the resulting vibrations and impacts pose a potential threat to the circuit boards. Therefore, a circuit board protection device is needed to help solve this problem. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a circuit board protection device to solve the technical problem that the overall protection of existing automotive circuit boards is inadequate. As automobiles experience various complex road conditions during driving, the resulting vibrations and impacts pose a potential threat to the circuit boards.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circuit board protection device, comprising a substrate, protruding plates symmetrically protruding from the top of the substrate, a mounting plate slidably disposed between the two protruding plates, a mounting cavity for mounting the circuit board body being provided on the mounting plate, protruding plates being equidistantly disposed within the mounting cavity, mounting holes being provided at the edge of the circuit board body, and a fixing component for fixing the circuit board body being mounted on the mounting plate.

[0006] A sliding cavity is provided on one side of each of the two protruding plates, and a buffer assembly for auxiliary mounting plate buffering is installed in the sliding cavity.

[0007] The present invention is further configured such that the buffer assembly includes a slide rod vertically fixed in the sliding cavity, and sliders are provided protruding from both ends of the mounting plate. The sliders are sleeved on the slide rod, and a buffer spring for assisting the slider to press and buffer is sleeved on the slide rod.

[0008] The present invention is further configured such that the slider has a through hole through which the slider rod passes, and a friction pad is embedded in the through hole.

[0009] The present invention is further configured such that a plurality of mounting holes are provided on the circuit board body, and the plurality of mounting holes are arranged in an array on the circuit board body.

[0010] The present invention is further configured such that the fixing component includes a fixing column vertically fixed in the mounting cavity, a receiving plate is sleeved on the fixing column, a threaded rod is threaded on the fixing column, and a fixing bolt is protruding from the top of the threaded rod.

[0011] The present invention is further configured such that a compression spring is sleeved and installed on the fixing column corresponding to the lower part of the receiving plate, and a compression spring is sleeved and installed on the bottom of the fixing bolt corresponding to the top of the circuit board body.

[0012] The present invention is further provided that fixing holes are drilled at all four corners of the substrate, and the fixing holes penetrate the protruding plate.

[0013] In summary, the present invention has the following beneficial effects: The present invention uses a buffer assembly vertically fixed to the protruding plate. When encountering vertical bumps or impacts, the mounting plate moves up and down, causing the slider to move as a whole. As the slider moves up and down, the buffer spring is compressed, thus achieving overall buffering of the vibration force. Simultaneously, when the slider slides along the slide bar, the sliding friction pad generates friction during the up-and-down sliding motion, effectively consuming the vibration force. Therefore, when encountering impacts, the circuit board body can be effectively buffered through auxiliary buffering, and subsequent vibrations or impacts can effectively prevent damage to the entire circuit board body.

[0014] The threaded rod at the bottom of the fixing bolt is threaded onto the fixing post through the fixed assembly. The fixing post and the threaded rod are threaded together. During the descent of the fixing bolt, two compression springs can stably clamp and position the circuit board body. This ensures clamping while also cushioning the falling force when encountering vertical vibrations, thus providing effective initial protection for the circuit board body. During installation, the preload of the springs can prevent the circuit board body from being over-fixed and damaged. At the same time, it can provide elastic protection for the circuit board body during vehicle movement, improving the overall service life of the circuit board body. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] A circuit board protection device, such as Figure 1-4 As shown, the substrate includes a base plate 1. Fixing holes 3 are drilled at all four corners of the base plate 1. The fixing holes 3 pass through the protruding plates 2. The top of the base plate 1 is symmetrically provided with protruding plates 2. The mounting plate 4 is slidably arranged between the two protruding plates 2. The mounting plate 4 has a mounting cavity for mounting the circuit board body 15. A sliding cavity is provided on one side adjacent to the two protruding plates 2. A buffer assembly 6 for buffering the mounting plate 4 is installed in the sliding cavity. The buffer assembly 6 includes a slide rod 8 vertically fixed in the sliding cavity. Slider 7 is provided at both ends of the mounting plate 4. The slider 7 is sleeved on the slide rod 8. A buffer spring 9 for pressing and buffering the slider 7 is sleeved on the slide rod 8. The slider 7 has a through hole through which the slide rod 8 passes. A friction pad 71 is embedded in the through hole.

[0022] By using the buffer assembly 6, which is vertically fixed to the protruding plate 2, the mounting plate 4 moves up and down when encountering vertical bumps and impacts. When the mounting plate 4 moves up and down, it drives the slider 7 to move as a whole. When the slider 7 moves up and down, it causes the buffer spring 9 to be compressed, thereby achieving overall buffering of the vibration force. At the same time, when the slider 7 slides along the slide rod 8, the friction pad 71 can generate friction force when sliding up and down, thereby effectively consuming the vibration force. Thus, when encountering impacts, the circuit board body 15 can be effectively buffered through auxiliary buffering, and the circuit board body 15 can be effectively prevented from being damaged as a whole when encountering vibrations or impacts in subsequent work.

[0023] The aforementioned mounting cavity is provided with protruding plates 5 at equal intervals. The edge of the circuit board body 15 is provided with mounting holes. Several mounting holes are provided on the circuit board body 15 and arranged in an array. The mounting plate 4 is provided with a fixing component 10 to assist in fixing the circuit board body 15. The fixing component 10 includes a fixing post 11 that is vertically fixed in the mounting cavity. A receiving plate 12 is sleeved on the fixing post 11. A threaded rod 141 is threaded on the fixing post 11. A fixing bolt 14 is protruding from the top of the threaded rod 141. A compression spring 13 is sleeved on the fixing post 11 below the receiving plate 12. A compression spring 13 is sleeved on the bottom of the fixing bolt 14 at the top of the circuit board body 15.

[0024] The threaded rod 141 at the bottom of the fixing bolt 14 is threaded and installed on the fixing post 11 through the fixing component 10. The fixing post 11 and the threaded rod 141 are threadedly engaged. At the same time, during the descent of the fixing bolt 14, the two compression springs 13 can stably clamp and position the circuit board body 15. In order to ensure clamping, the compressed springs can further buffer the falling force when encountering vertical vibration, thus providing effective initial protection for the circuit board body 15. During installation, the preload of the springs can prevent the circuit board body 15 from being over-fixed and damaged. At the same time, it can provide elastic protection for the circuit board body 15 during vehicle movement, thereby improving the overall service life of the circuit board body 15.

[0025] The working principle of this utility model:

[0026] When the circuit board body 15 needs to be installed, align the mounting holes on the circuit board body 15 with the fixing posts 11, and insert the threaded rod 141 at the bottom of the fixing bolt 14 onto the fixing post 11. The fixing post 11 and the threaded rod 141 are threadedly engaged. Simultaneously, during the descent of the fixing bolt 14, the two compression springs 13 provide stable clamping and positioning for the circuit board body 15. This ensures clamping while also cushioning the falling force during vertical vibrations, thus providing effective initial protection for the circuit board body 15.

[0027] When the vibration force of up-and-down bumping is large, the mounting plate 4 moves up and down. When the mounting plate 4 moves up and down, it drives the slider 7 to move as a whole. When the slider 7 moves up and down, it causes the buffer spring 9 to be compressed, thereby achieving overall buffering of the vibration force. At the same time, when the slider 7 slides along the slide rod 8, the friction pad 71 can generate friction force when sliding up and down, thereby effectively consuming the vibration force.
