Abstract
Description
Technical Field
[0001] This utility model relates to the field of shielding technology, and in particular to a shielding cover for automotive electronic components that can be quickly installed. Background Technology
[0002] The shielding cover consists of legs and a cover body, with the legs and cover body being movably connected. The cover body is spherical in shape. This component is mainly used in automobiles, mobile phones, GPS and other fields. It is used to prevent electromagnetic interference and to shield components on the PCB board. The shielding cover is generally made of 0.2mm thick stainless steel and nickel silver. Nickel silver is a metal shielding material that is easy to tin.
[0003] Most existing electronic component shielding covers are directly soldered onto the circuit board to achieve the effect of shielding electromagnetic waves. However, these shielding covers are mostly disposable, and it is very troublesome to remove them when electronic components malfunction. Utility Model Content
[0004] To address the technical problem that most existing electronic component shielding covers are directly soldered onto circuit boards to achieve electromagnetic wave shielding, but disassembling the shielding cover is very troublesome when the electronic component malfunctions, this utility model provides a quick-installable automotive electronic component shielding cover device.
[0005] This utility model is achieved using the following technical solution: a quick-installable automotive electronic component shielding cover, comprising a base plate, wherein a PCB board is mounted on the top center of the base plate, characterized in that the top of the base plate has symmetrically arranged grooves, and two vertically parallel inner sidewalls of the grooves are fixedly connected to stop blocks, a cover body is provided on the outer side of the PCB board, and a conical block that engages with the stop blocks is provided at the bottom end of the cover body, the conical block being made of a highly resilient material, and a height adjustment component being provided between the conical block and the bottom end of the cover body.
[0006] Through the above technical solution, a pair of stops are symmetrically fixed on the two inner sides of the groove at the top of the base plate, and a conical block that engages with the stops is provided at the bottom of the cover. The material of the conical block has high resilience, so that after the conical block is inserted between the pair of stops, it immediately rebounds to the initial state, thereby realizing the quick installation of the cover.
[0007] When it is necessary to remove the cover, push the cover upwards towards the base plate. At this time, the cone block will slide out from between a pair of stops into the groove, thus releasing the cone block from limiting the cover.
[0008] As a further improvement to the above solution, the adjustment component includes a fixed cylinder fixed to the top of the conical block and a movable column fixed to the bottom of the cover. The movable column slides inside the fixed cylinder. The outer side of the fixed cylinder is symmetrically provided with a linear array of limiting holes. The limiting holes are slidably connected to the limiting columns. The outer side of the movable column is symmetrically fixed with a fixed block. The fixed block is fixed with a return spring. The top end of the return spring is fixedly connected to the bottom end of the limiting column.
[0009] Using the above technical solution, the pressing limit post moves from inside the limit hole into the fixed cylinder and compresses the return spring inside the fixed block until the limit post disengages from the current limit hole, releasing the restriction of the cover and allowing the cover to adjust its height according to PCB boards of different thicknesses. Then the limit post will slide back into the new limit hole.
[0010] As a further improvement to the above solution, the end of the conical block is provided to be arc-shaped, and the conical block slides between a pair of stops.
[0011] Through the above technical solution, the arc-shaped conical block can support and limit the cover when it is installed on the base plate by the arc-shaped opening angle.
[0012] As a further improvement to the above solution, the length of the pair of stops is half the length of the groove, and the length of the conical block is the same as that of the stops.
[0013] With the above technical solution, the conical block and the stop block have the same length, and the stop block is half the length of the groove, so that the conical block can slide between the stop blocks to make the cover detach from the bottom plate.
[0014] As a further improvement to the above solution, heat dissipation holes are provided on the four outer sides and the top of the cover.
[0015] The above technical solution can effectively dissipate heat from the PCB board inside the enclosure, thereby improving the performance of the PCB board.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention features a pair of symmetrically fixed blocks vertically parallel to the inner sides of a groove at the top of the base plate, and a conical block at the bottom of the cover that engages with the blocks. The conical block is made of a material with high resilience, allowing it to be inserted between the blocks and immediately spring back to its initial state, thus enabling quick installation of the cover. When the cover needs to be removed, it is pushed upwards from the base plate, at which point the conical block slides out from between the blocks into the groove, releasing its restriction on the cover and enabling quick installation and removal of the shielding cover.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Please combine Figures 1-4 This embodiment provides a quick-installable automotive electronic component shielding cover, comprising a base plate 1, with a PCB board 2 mounted on the top center of the base plate 1. The base plate 1 has symmetrically arranged grooves 3 at its top, with stops 4 fixed to the two vertically parallel inner sidewalls of the grooves 3. A cover 5 is provided on the outer side of the PCB board 2, and a conical block 6, which engages with the stops 4, is provided at the bottom of the cover 5. The conical block 6 is made of a highly resilient material, and a height adjustment assembly is provided between the conical block 6 and the bottom of the cover 5.
[0026] A pair of stop blocks 4 are symmetrically fixed to the two inner sides of the groove 3 at the top of the base plate 1 vertically parallel to each other, and a conical block 6 that engages with the stop blocks 4 is provided at the bottom of the cover 5. The material of the conical block 6 has high resilience, so that after the conical block 6 is inserted between the pair of stop blocks 4, it immediately rebounds to the initial state, thus realizing the quick installation of the cover 5.
[0027] When it is necessary to remove the cover 5, push the cover 5 to move horizontally upwards towards the base plate 1. At this time, the conical block 6 will slide out from between a pair of stops 4 into the groove 3, so that the conical block 6 releases its restriction on the cover 5.
[0028] Combination Figures 2-4The adjustment assembly includes a fixed cylinder 7 fixed to the top of the conical block 6 and a movable column 8 fixed to the bottom of the cover 5. The movable column 8 slides inside the fixed cylinder 7. The outer side of the fixed cylinder 7 is symmetrically provided with a linear array of limiting holes 9. Limiting columns 10 are slidably connected inside the limiting holes 9. A fixed block 13 is symmetrically fixed to the outer side of the movable column 8. A return spring 11 is fixed inside the fixed block 13. The top end of the return spring 11 is fixedly connected to the bottom end of the limiting column 10.
[0029] By pressing the limiting post 10 inside the limiting hole 9 and moving it into the fixed cylinder 7, and compressing the return spring 11 inside the fixed block 13, until the limiting post 10 disengages from the current limiting hole 9, the restriction of the cover 5 is released, so that the cover 5 can adjust its height according to the PCB board 2 of different thicknesses, and then the limiting post 10 will slide back into the new limiting hole 9.
[0030] Combination Figure 2 The end of the cone block 6 is arc-shaped, and the cone block 6 slides between a pair of stops 4.
[0031] By setting the end of the conical block 6 in an arc shape, the cover 5 can be supported and limited by the arc opening angle when it is installed on the base plate 1.
[0032] Combination Figure 2 The length of a pair of stop blocks 4 is half the length of the groove 3, and the length of the conical block 6 is the same as that of the stop blocks 4.
[0033] By having the cone block 6 and the stop block 4 have the same length, and the stop block 4 is half the length of the groove 3, the cone block 6 can slide between the stop blocks 4, allowing the cover 5 to detach from the base plate 1.
[0034] Combination Figure 1 The outer sides and top of the cover 5 are provided with heat dissipation holes 12.
[0035] By opening heat dissipation holes 12 on the four sides and top of the cover 5, the PCB board 2 inside the cover 5 can be effectively cooled, thereby improving the performance of the PCB board 2.
[0036] The implementation principle of the quick-installable automotive electronic component shielding cover in this application embodiment is as follows:
[0037] Before installation, align the conical block 6 at the bottom of the cover 5 with the pair of stops 4 inside the groove 3, and then move the cover 5 down. Due to the high resilience of the material of the conical block 6, the arc-shaped surface at the end of the conical block 6 will collide and deform with the gap between the pair of stops 4 until the end of the conical block 6 is completely inside the groove 3. At this time, the arc-shaped side of the rebounded conical block 6 will collide with the inner side of the pair of stops 4 to limit and fix the cover 5.
[0038] When it is necessary to remove the cover 5, push the cover 5 to move horizontally upwards towards the base plate 1. At this time, the conical block 6 will slide out from between a pair of stops 4 into the empty part of the groove 3, so that the conical block 6 releases its restriction on the cover 5.
[0039] When the height of the cover 5 needs to be adjusted, press the pair of limiting posts 10 on the fixing cylinder 7 simultaneously to move them inside the limiting hole 9 towards the inside of the fixing cylinder 7. As the limiting posts 10 move, the reset spring 11 inside the fixing block 13 will be compressed simultaneously until the limiting posts 10 disengage from the current limiting hole 9. At this point, the limiting of the cover 5 is released, and the cover 5 can be pushed up to the appropriate height of the PCB board 2. Then the limiting posts 10 will slide back into the new limiting hole 9.
[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
