Description

Technical Field

[0001] The utility model relates to the technical field of GPS, in particular to a protective box for a GPS positioning module. Background Art

[0002] GPS is a system that uses GPS positioning satellites to perform real-time positioning and navigation around the world. Since the GPS positioning chip is a high-precision electronic device, a shell is set on the outside to protect it when it is used. In the Chinese utility model patent with announcement number CN214704005U, a GPS locator installation structure on a container is disclosed, including a GPS locator body and a connecting component. The GPS locator is set under the cover plate, and the connecting component under the GPS locator has a buffer structure added, which can effectively protect the GPS locator from damage to the internal parts of the GPS locator due to bumps and other reasons during container transportation. In the above structure, in order to reduce the impact of bumps on the GPS locator, a spring is set in the base. The spring will be compressed or stretched when it is vibrated, and an opposite force will also be generated, which will cause the GPS locator to be subjected to double vibration, the overall shaking effect will be aggravated, and the degree of bumps will increase. To this end, we designed a protective box for the GPS positioning module. Utility Model Content

[0003] In order to solve the technical problem of shaking of the GPS positioning module caused by bumps, the utility model provides a protective box for the GPS positioning module.

[0005] As a further improvement of the above scheme, the protective shell includes a top plate, the left and right ends of the top plate are bent downward to form a connecting plate 1, and the front and rear sides of the top plate are bent downward to form side panels, and the outward sides of the two side panels are respectively provided with fixing plates, and the left and right sides of the fixing plate are bent to form connecting plate 2, and the connecting plate 1 is welded to the connecting plate 2.

[0006] As a further improvement of the above scheme, a limiting frame is arranged above the mounting plate, and the thermally conductive silicone sheet is pasted in the limiting frame. The thermally conductive silicone sheet is soft and can be used with high compressibility, and has a shock-absorbing effect. It can be used as a vibration absorber, and can provide a certain degree of shock absorption for the GPS positioning module installed above it, and the inward side of the two side panels is in contact with the front and rear ends of the limiting frame to improve the sealing performance.

[0007] As a further improvement of the above solution, the bending curvatures of the connecting plates 1 and 2 are consistent, and the bending curvatures of the connecting plates 1 and 2 are consistent with those of the fixed strips. The connecting plates 1 and 2 can be completely fitted on top of the fixed strips, thereby ensuring sealing.

[0008] As a further improvement of the above solution, a heightened notch is formed between the bottom of the mounting plate and the fixed strips on the left and right sides thereof, and a plurality of linearly distributed heat dissipation fins are arranged in the heightened notch, and the bottom ends of the heat dissipation fins do not contact the upper surface of the rubber pad. The design of the heat dissipation fins increases the heat dissipation area below the mounting plate, thereby improving the heat dissipation effect;

[0009] The plurality of heat dissipation fins are longitudinally arranged in the heightened notch in the front and rear direction. The heightened notch is designed to penetrate the front and rear direction. The heat dissipation fins are designed along the direction of the opening to facilitate the circulation of airflow.

[0012] 1. The utility model arranges a rubber pad under the mounting plate, and makes the mounting plate contact the rubber pad through two fixed strips, so that the force transmitted after absorbing the vibration is further reduced. The thermal conductive silicone sheet is arranged to further reduce the vibration, so that the overall vibration reduction effect is good and will not cause too much shaking to the GPS positioning module;

The fixing plate 32 is used to be connected to the front and rear sides of the mounting plate 2, and the connecting plates 1 311 and 2 321 are used to be connected to the two fixing strips 21, and sealing gaskets are pressed at their connections, which can improve the overall sealing performance, prevent external water stains from entering, and ensure safety.

[0025] A limit frame 5 is set above the mounting plate 2, and a thermally conductive silicone sheet 6 is pasted in the limit frame 5. The thermally conductive silicone sheet 6 is soft and can be used with high compressibility. It has a shock-absorbing effect and can be used as a vibration absorber. It can provide a certain degree of shock absorption for the GPS positioning module installed above it, and the inward sides of the two side panels 312 are in contact with the front and rear ends of the limit frame 5 to improve the sealing performance.

[0026] The curvatures of the connecting plate 1 311 and the connecting plate 2 321 are consistent, and the curvatures of the connecting plate 1 311 and the fixed strip 21 are consistent.

[0027] A heightened notch 22 is formed between the bottom of the mounting plate 2 and the fixed strips 21 on the left and right sides thereof. A plurality of linearly distributed heat dissipating fins 4 are arranged in the heightened notch 22, and the bottom ends of the heat dissipating fins 4 do not contact the upper surface of the rubber pad 1. The design of the heat dissipating fins 4 increases the heat dissipation area below the mounting plate 2, thereby improving the heat dissipation effect.
