Description

Technical Field

[0001] The utility model relates to the technical field of GNSS receivers, in particular to a GNSS receiver with strong impact resistance. Background Art

[0002] A GNSS receiver is a receiver that can simultaneously receive signals from two or more GNSS systems. A so-called GNSS-compatible receiver is a receiver that can simultaneously receive signals from two or more GNSS systems.

[0003] Chinese patent document CN217879653U discloses a GNSS receiver with strong impact resistance, including a GNSS receiver body, a fixing plate provided on the upper surface of the GNSS receiver body, and four symmetrically arranged first connecting plates fixed to the upper surface of the GNSS receiver body. A fixing rod is fixedly connected to the first connecting plate, and a second connecting plate is sleeved on the surface of the fixing rod and fixedly connected to the fixing plate. By providing the fixing plate, when the top of the GNSS receiver body is hit during outdoor use, the fixing plate is squeezed and moved downward. When the fixing plate moves downward, it drives the second connecting plate to slide on the surface of the fixing rod. Subsequently, the first spring is squeezed and contracts. At this time, the first spring can cushion the impact force generated by the collision, achieving an impact resistance effect, preventing the GNSS receiver body from being damaged by impact caused by bad weather when used outdoors, which would affect its performance and lifespan.

[0004] The existing technology has the following problems:

[0005] 1. Existing GNSS receivers with strong impact resistance can only protect the top of the receiver when protecting the device from impact, which will increase the impact on the side of the receiver and is not conducive to the long-term use of the receiver.

[0006] 2. Existing GNSS receivers with strong impact resistance work in outdoor deserts, which causes the air to carry a lot of dust. Dust falling on the connector of the receiver will cause the connector to fail and affect the normal operation of the device. Utility Model Content

[0008] A GNSS receiver with strong impact resistance includes a receiver, wherein the lower end of the receiver is fixedly connected to a base plate, the upper end of the receiver is provided with two impact resistance devices, and the front end of the receiver is detachably connected to a dustproof device, and the dustproof device is located above the base plate.

[0009] Preferably, a display screen is fixedly connected to the front end of the receiver, an adjustment button is provided below the display screen, and a rear end of the adjustment button is fixedly connected to the front end of the receiver.

[0010] Preferably, the four corners of the front end of the receiver are fixedly connected with fixing buckles.

[0011] Preferably, the anti-impact device includes four brackets one, the lower end of the bracket one is fixedly connected to the upper end of the receiver, the interior of the bracket one is movably connected to a rotating rod, the front and rear ends of the rotating rod are movably connected to an anti-impact plate, and the surface of the anti-impact plate is provided with multiple signal holes.

[0013] Preferably, the dustproof device includes a dustproof cover, and two fixing holes are provided at the upper and lower ends of the dustproof cover.

[0014] Preferably, a plurality of air outlets are provided at the left end of the dust cover.

[0015] Preferably, an air inlet is provided at the right end of the dust cover, an air filter plate is fixedly connected to the inside of the air inlet, a bracket 2 is fixedly connected to the inside of the air inlet, a rotating motor is fixedly connected to the left end of the bracket 2, a fan is fixedly connected to the output end of the rotating motor, and the fan is located on the left side of the air filter plate.

[0016] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0017] 1. The utility model provides a GNSS receiver with strong impact resistance. Through the joint action of the bracket, the rotating rod, the anti-impact plate, the signal hole, the telescopic column, the telescopic spring, and the sliding column, the receiver can be protected from impact in multiple directions, making the receiver safer during operation and improving the service life of the device. When the impact acts on the upper side, the upper anti-impact plate will press down the sliding column, releasing the potential energy generated by the impact to the telescopic spring inside the telescopic column, and the anti-impact plate will rotate along the rotating rod on the bracket, so that the anti-impact plate on the side of the device will extend outward, which is convenient for resisting the impact from the side and improving the safety of the device.

[0018] 2. The utility model provides a GNSS receiver with strong impact resistance. Through the joint action of the dust cover, fixing holes, air outlet, air inlet, air filter plate, bracket 2, rotating motor and fan, the operating end of the receiver can be protected, so that the operating interface is kept in a clean and tidy environment, and dust and sand are effectively prevented from entering the interface to affect the instrument. By manually pressing the dust cover, the fixing buckle on the receiver is stuck in the fixing hole on the dust cover to fix the dust cover, and then the rotating motor on the bracket 2 is started to rotate, driving the fan to rotate, so that the outside air enters the inside of the dust cover through the air inlet, the air filter plate filters the incoming air, and the filtered air passes through the display screen and the adjustment button to clean the interface. The cleaned air carries the dust through the air outlet to the outside. BRIEF DESCRIPTION OF THE DRAWINGS
