Description

Technical Field

[0001] The present invention relates to the technical field of satellite navigation technology, and in particular to a shock-resistant Beidou navigation receiver. Background Art

[0002] The BeiDou Navigation Satellite System (BDS) is a satellite navigation system independently built and operated by China, driven by national security and economic and social development needs. It is a critical national space infrastructure providing all-weather, all-day, high-precision positioning, navigation, and timing services to users worldwide. Unlike GPS, the BeiDou Navigation Satellite System utilizes active, two-dimensional, two-way ranging. The BeiDou system consists of two geostationary satellites, a central control system, a calibration system, and various user terminals. The central control system simultaneously transmits an interrogation signal to both satellites, which is then broadcast via satellite transponders to users within the service area. Users respond to the interrogation signal from one of the satellites and simultaneously send a response signal to both satellites, which is then forwarded back to the central control system. The central control system receives and demodulates the user's signal and then processes the data based on the service requested.

[0003] In the existing field of satellite navigation technology, when sending and receiving information, the Beidou system uses a receiver to transmit and receive information. However, the receiver has no protection measures. Therefore, when in use, it is extremely susceptible to being hit by external objects or falling. At this time, the receiver will collide with the external object or the ground. Under the action of the impact force, the receiver will be damaged, thereby affecting its normal use.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figures 1-6 A shock-resistant Beidou navigation receiver includes a main body 1, two sets of shaft seats 2 are welded on both sides of the main body 1, and the two sets of shaft seats 2 are equipped with buffer mechanisms for protecting the main body 1.

[0019] The buffer mechanism includes a connecting rod 4 with a pin installed on the shaft seat 2, and a first slider 5 is installed on the pin of the free end of the connecting rod 4. A buffer plate 6 is installed on the first slider 5. The outer plate of the buffer plate 6 is made of rubber, and the bottom plate of the buffer plate 6 is made of hard material. The bottom plate is made of aluminum alloy, which has good processing performance, strong corrosion resistance, high compressive strength, and durability. It can cope with a variety of environments. The interior of the buffer plate 6 is a continuous honeycomb structure. The honeycomb structure is the basic structure of the honeycomb. It is a structure composed of a series of regular hexagonal single rooms, with the room openings all facing downward or to one side, and symmetrically arranged back to back. In this structure, each node has multiple adjacent nodes, so it has the characteristics of multi-path transmission. In addition, the honeycomb structure also has high resistance to extrusion pressure, can absorb impact from the outside, and improve the impact resistance of the device.

[0020] Both ends of the buffer plate 6 are pin-mounted with connecting plates 7, and the free end of the connecting plate 7 is pin-mounted with an anti-fall frame 8 connected by a pin. The anti-fall frame 8 has an arc-shaped structure, and the buffer plate 6 and the anti-fall frame 8 deform with each other, similar to the thin shell structure in a building, and the force received is evenly distributed on the buffer plate 6 and the anti-fall frame 8 to reduce the pressure on each part, and the outer side of the anti-fall frame 8 is equipped with a rubber pad for impact prevention. The rubber pad refers to a highly elastic polymer material with reversible deformation. It is elastic and can be deformed under the action of external force. It can return to its original shape after the external force is removed. It has the same function as the buffer plate 6, both of which play a buffering role, absorbing the impact force from the outside to maximize the anti-impact effect of the device.

[0021] Two groups of guide grooves 9 are provided at the bottom end of the main body 1, and columns 10 are slidably installed in the two groups of guide grooves 9. The guide grooves 9 are provided on the outer wall of the bottom end of the main body 1, which can reduce the mass of the various components that the main body 1 needs to bear. Transmission rods 11 are pin-mounted on the two groups of columns 10, and the free end pins of the two groups of transmission rods 11 are pin-mounted with a second slider 12 that is slidably connected to the bottom end of the main body 1. A strong spring 13 and a telescopic rod 22 that are fixedly connected to the main body 1 are fixedly installed on the second slider 12. The strong spring 13 is located on the outside of the telescopic rod 22. The strong spring 13 is a mechanical part that works by elasticity. It is made of elastic material and is deformed under the action of external force. It returns to its original shape after the external force is removed. The telescopic rod 22 guides the strong spring 13 to prevent the strong spring 13 from bending during the deformation process, which affects the performance of the strong spring 13.

[0022] A transmission frame 14 fixedly connected to the buffer plate 6 is fixedly mounted on the column 10. The two sets of transmission rods 11 and the transmission frame 14 form a triangular structure. One end of the transmission frame 14 is a triangular structure for enhancing the stability of the device. The triangular structure makes the force evenly distributed between the three points. This distribution method can reduce the phenomenon of stress concentration, thereby improving the tensile strength and compressive strength of the material, and has stability, firmness, firmness, and pressure resistance. It ensures that the transmission frame 14 will not be deformed, thereby avoiding affecting the impact resistance of the device.

[0023] Two sets of mounting frames 3 are welded on both sides of the main body 1. The two sets of shaft seats 2 and mounting frames 3 are symmetrically distributed on both sides of the main body 1, and the top of the mounting frame 3 is higher than the main body 1. The two sets of mounting frames 3 are equipped with a shielding mechanism for protecting the operating panel of the main body 1.

[0024] The shielding mechanism includes a coil spring 18 mounted on a mounting frame 3 on one side. The coil spring 18 is a spring whose spiral line is in one plane. The spring is a spring whose material is wound into a flat spiral shape. One end of the spring is fixed, and after the torque is applied to the other end, the material is subjected to a bending moment, resulting in bending elastic deformation. Therefore, the spring is torsionally deformed in its own plane. The size of its deformation angle is proportional to the torque. It has high torsional force and multi-angle torsional moment, so it is used in mechanisms that work for a long time. It has the characteristics of not easy fatigue and self-recovery. A mounting roller 15 fixedly connected to the free end of the coil spring 18 is rotatably mounted between the two sets of mounting frames 3. A shielding cloth 16 is placed on the mounting roller 15. The shielding cloth 16 is made of a mesh made of an anti-inflammatory net. It has the characteristics of high strength and easy cleaning, and is light in weight. It will not bring weight burden to the entire device, and can also resist external impact to form effective protection for the main body 1. A buckle 17 is mounted on the shielding cloth 16.

[0025] A slot plate 19 with a through hole is welded between the mounting frame 3 on the other side. The through hole of the mounting roller 15 and the slot plate 19 are on the same horizontal plane, and the width of the through hole is greater than the thickness of the buckle 17. A wedge 20 is welded to the bottom end of the slot plate 19, and a bayonet 21 for matching connection with the buckle 17 is provided on the wedge 20. Since the coil spring 18 has the ability of self-recovery, it will always control the shielding cloth 16 to be wrapped around the mounting roller 15, and then there is a force to control the reset of the buckle 17. The bayonet 21 limits the reset path of the buckle 17, so that the buckle 17 can be controlled to conflict with the wedge 20, so that the shielding cloth 16 is in a taut state, maximizing its impact resistance.

[0026] It should be noted that the specific models and specifications of the coil spring 18 and the telescopic rod 22 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0027] The present invention can be explained through the following operation mode: When the left and right sides of the main body 1 are impacted, the buffer plate 6 will be the first to be impacted. At this time, the internal structure of the buffer plate 6 will first absorb the impact force. When the absorbed force reaches a saturated state, the two sets of first sliders 5 slide back to back, and the buffer plate 6 is pulled inward by the connecting rod 4. At this time, the angle between the two sets of anti-fall frames 8 will be reduced, thereby evenly distributing the remaining impact force to the buffer plate 6 and the anti-fall frame 8. The transmission frame 14 will slide inward through the column 10, and the angle between the two sets of transmission rods 11 will become smaller, thereby driving the second slider 12 to slide upward. At this time, the strong spring 13 and the telescopic rod 22 will be compressed to absorb the remaining impact force, thereby achieving an impact resistance effect; When the upper and lower ends of the main body 1 are impacted, the angle between the two sets of anti-fall frames 8 will increase, thereby pulling and driving the buffer plate 6 to move outward. At this time, the two sets of first sliders 5 slide towards each other, and the transmission frame 14 will move outward. As a result, the angle between the two sets of transmission rods 11 will increase, thereby driving the strong spring 13 and the telescopic rod 22 to extend to absorb the generated impact force; When the main body 1 is stationary, pull the buckle 17 and drive the shielding cloth 16 through the slot plate 19. At this time, the installation roller 15 will rotate clockwise, and the coil spring 18 will be wound around the installation roller 15. Then, put the buckle 17 on the wedge block 20, and control the buckle 17 to cooperate with the bayonet 21. The coil spring 18 will always make the installation roller 15 have a counterclockwise rotation force, so the shielding cloth 16 will remain taut to block external dust or objects.
