Description

Technical Field

[0001] The utility model relates to the technical field of shielding covers, and specifically relates to a wear-resistant shielding cover prototype model. Background Technique

[0002] With the rapid development of technology, for electronic devices such as vehicle-mounted navigation, dash cams, and in-vehicle TVs, there is often signal interference between internal electronic components. Using a shielding cover can shield the electronic components on the printed circuit board to prevent electromagnetic interference. Generally speaking, a prototype model is one or several made according to the product appearance drawing or structure drawing without opening a mold, used to check the rationality of the appearance or structure. The prototype model is also called the first prototype in different places;

[0003] After retrieval, the patent number is CN205454371U, which discloses a shielding cover. There are no heat dissipation through holes above the radio frequency device, and heat dissipation through holes are opened at other positions, which not only ensures the signal shielding of the radio frequency device but also ensures the heat dissipation of the chip. At the same time, elastic pieces are arranged around the radio frequency device, which can further improve the shielding effect; however, when this device is in use, it will be extruded externally, and there are no measures set for the current shielding cover, resulting in the shielding cover being easily worn, reducing the service life, and easily damaging the internal components. For this reason, we propose a wear-resistant shielding cover prototype model. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wear-resistant shielding cover prototype model.

[0005] To solve the problems raised in the above background technique, the utility model provides the following technical solution: a wear-resistant shielding cover prototype model, including a device main body. At a position close to the upper side of the inner side wall of the device main body, an elastic piece is arranged. At a position close to the center of the inner wall of the device main body, a stop block is installed. On the side wall of the stop block, a second fixing plate is arranged. On both side walls of the second fixing plate, first fixing plates are arranged. On both sides of the lower end of the first fixing plate, buffer cylinders are arranged. At a position close to the lower side of the inner side wall of the buffer cylinder, a connecting column is installed. At the lower end of the connecting column, a buffer block is arranged. At the upper end of the second fixing plate, a heat-conducting copper sheet is arranged.

[0006] Preferably, at a position close to the center of the side wall of the buffer cylinder, a slider is fixedly connected, and a chute is opened at the position where the slider contacts the device main body.

[0007] Preferably, at the central position of the upper end of the connecting column, a spring is elastically connected, and the upper end of the spring is elastically connected to the buffer cylinder, and the spring is located inside the buffer cylinder.

[0008] Preferably, bolts are penetrated through the four corners at the upper end of the device main body, and the outer side wall of the bolts is threadedly connected with the device main body.

[0009] Preferably, a water tank is arranged at the position near the lower left corner at the upper end of the heat-conducting copper sheet. A heat-dissipating copper pipe is installed at the position near the lower side of the left side wall of the water tank. A connecting block is installed at the position near the center at the upper end of the heat-conducting copper sheet. A protection plate is installed at the upper end of the connecting block. A plurality of heat-dissipating plates are arranged at the position near the center at the upper end of the protection plate.

[0010] Preferably, a blocking plate is movably connected to the position near the upper side of the inner wall of the water tank, and a pulling block is fixedly connected to the center position at the upper end of the blocking plate.

[0011] Preferably, a plurality of heat-dissipating plates are arranged at the position near the center at the upper end of the protection plate, and filter plates are fixedly connected to the inner side walls of the plurality of heat-dissipating plates.

[0012] With the above technical solution, when the upper part of the device main body is externally squeezed, the device main body squeezes the internal heat-conducting copper sheet. At this time, the second fixing plate and the first fixing plate will be squeezed by the heat-conducting copper sheet, so that the buffer cylinder, under the cooperation of the spring and the connecting column, enables the buffer block to squeeze downward. At the same time, through the action of the first fixing plate, the buffer cylinder impacts upward through the cooperation of the slider to offset the squeezing force, thereby protecting the safety of the internal components. At the same time, through the action of the blocking block, the squeezing force from the side can also be offset, so that when the shielding cover is used in daily life and is subjected to some external squeezing, it can be buffered, and the internal components will not be damaged, improving the wear resistance of the shielding cover and increasing the service life of the shielding cover;

[0013] With the above technical solution, the blocking plate is pulled up through the pulling block to cancel the sealing of the water tank by the blocking plate, and then water is injected into the water tank. After the water injection is completed, the blocking plate seals the water tank again. Then when the shielding cover shields the components, the components will generate heat. At this time, the heat-conducting copper sheet will absorb the heat, and then through the cooperation of the water in the water tank and the heat-dissipating copper pipe, the heat inside the heat-conducting copper sheet will be cooled. At the same time, through the cooperation of the protection plate and the heat-dissipating plates, a certain amount of air cooling can also cool the heat-conducting copper sheet, and the heat-conducting copper sheet seals the upper part of the components, so that the shielding effect will not be affected, enabling the shielding cover to have the function of dissipating heat for the internal components and improving the functionality of the shielding cover.

Specific embodiments

[0019] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a wear-resistant shielding cover hand model, including a device main body 1, an elastic sheet 3 is arranged at a position close to the upper side of the inner side wall of the device main body 1, a stop block 11 is installed at a position close to the center of the inner wall of the device main body 1, a second fixing plate 10 is arranged on the side wall of the stop block 11, first fixing plates 9 are arranged on both side walls of the second fixing plate 10, buffer cylinders 5 are arranged on both sides of the lower end of the first fixing plate 9, a connecting column 7 is installed at a position close to the lower side of the inner side wall of the buffer cylinder 5, a buffer block 8 is arranged at the lower end of the connecting column 7, and a heat-conducting copper sheet 12 is arranged at the upper end of the second fixing plate 10.

[0021] Sliders 4 are fixedly connected to the positions close to the center of the side walls of the buffer cylinders 5, and chutes are provided at the positions where the sliders 4 are in contact with the device main body 1.

[0022] The center position of the upper end of the connecting column 7 is elastically connected with a spring 6, and the upper end of the spring 6 is elastically connected with the buffer cylinder 5, wherein the spring 6 is located inside the buffer cylinder 5.

[0023] During use, when the upper end of the device body is externally squeezed, the device body 1 will squeeze the heat-conducting copper sheet 12. At this time, the heat-conducting copper sheet 12 will squeeze the first fixing plate 9 and the second fixing plate 10. Then, the first fixing plate 9 will squeeze the buffer cylinder 5, causing the buffer cylinder 5 to move downward along the chute inside the device body 1 through the slider 4. At this time, the buffer cylinder 5 will contact the lower part through the buffer block 8, so that the connecting column 7 will squeeze the spring 6. Then, due to the elasticity of the spring 6, the buffer cylinder 5 will move upward through the slider 4 in the chute, thereby offsetting the squeezing force. At the same time, the squeezing forces from both sides will be offset by the second fixing plate 10 and the stop block 11, enabling the shielding cover to be buffered when subjected to some external squeezing during daily use, preventing the internal components from being damaged, improving the wear resistance of the shielding cover, and increasing the service life of the shielding cover.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a wear-resistant shielding cover prototype. A water tank 13 is arranged at the upper end of the heat-conducting copper sheet 12 near the lower left corner. A heat-dissipating copper pipe 15 is installed at a position near the lower side of the left side wall of the water tank 13. A connecting block 16 is installed at a position near the center of the upper end of the heat-conducting copper sheet 12. A protective plate 17 is installed at the upper end of the connecting block 16. Multiple heat-dissipating plates 18 are arranged at a position near the center of the upper end of the protective plate 17.

[0025] A blocking plate 14 is movably connected to a position near the upper side of the inner wall of the water tank 13, and a pull block 20 is fixedly connected to the center position of the upper end of the blocking plate 14.

[0026] Multiple heat-dissipating plates 18 are arranged at a position near the center of the upper end of the protective plate 17, and filter plates 19 are fixedly connected to the inner side walls of the multiple heat-dissipating plates 18.

[0027] Specifically, pull up the blocking plate 14 through the pull block 20 to cancel the sealing of the water tank 13 by the blocking plate 14. Then, inject water into the water tank 13. After the water injection is completed, make the blocking plate 14 seal the water tank 13 again. Then, when the shielding cover shields the components, the components will generate heat. At this time, the heat-conducting copper sheet 12 will absorb the heat, and then the water inside the water tank 13 will flow into the heat-dissipating copper pipe 15, enabling the water inside to cool most of the positions of the heat-conducting copper sheet 12. At the same time, the heat-dissipating plates 18 can suck the external wind into the protective plate 17, and then a certain amount of air cooling can also cool the heat-conducting copper sheet 12. Then, the filter plates 19 filter some sundries to prevent them from entering the shielding cover. Moreover, the heat-conducting copper sheet 12 seals the upper part of the components, so that the shielding effect will not be affected, enabling the shielding cover to have the function of dissipating heat for the internal components and improving the functionality of the shielding cover.

[0028] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
