Description

Technical Field

[0001] This invention relates to the field of satellite navigation technology, and in particular to a shock-resistant BeiDou navigation receiver. Background Technology

[0002] The BeiDou Navigation Satellite System (BDS) is a satellite navigation system independently constructed and operated by China to meet national security and economic and social development needs. It is a crucial national space infrastructure providing all-weather, all-time, high-precision positioning, navigation, and timing services to users worldwide. Unlike GPS, the BeiDou system is an active, two-way ranging, two-dimensional navigation system. The BeiDou system consists of two geostationary satellites, a central control system, a calibration system, and various user terminals. First, the central control system simultaneously sends an inquiry signal to both satellites, which is then broadcast to users within the service area via satellite transponders. Users respond to the inquiry signal from one satellite and simultaneously send response signals to both satellites, which are relayed back to the central control system. The central control system receives and demodulates the signals sent by the users and then performs corresponding data processing based on the requested service content.

[0003] In the field of existing satellite navigation technology, when transmitting and receiving information, the BeiDou system uses receivers. However, these receivers have no protective measures, making them highly susceptible to impacts from external objects or drops during use. In such cases, the receiver may impact with external objects or the ground, causing damage and affecting its normal operation. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of receivers being easily damaged in the prior art, and to propose an impact-resistant Beidou navigation receiver.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An impact-resistant Beidou navigation receiver includes a main body, with two sets of bearings welded to both sides of the main body. The two sets of bearings are equipped with buffer mechanisms for protecting the main body. Two sets of mounting brackets are welded to both sides of the main body, and the two sets of mounting brackets are equipped with shielding mechanisms for protecting the main body's operation panel.

[0007] Preferably, the two sets of bearings and mounting brackets are symmetrically distributed on both sides of the main body, and the top of the mounting bracket is higher than the main body.

[0008] Preferably, the buffer mechanism includes a connecting rod pinned to a bearing seat, a first slider pinned to the free end of the connecting rod, a buffer plate mounted on the first slider, connecting plates pinned to both ends of the buffer plate, and a drop protection frame pinned to the free end of the connecting plate.

[0009] The bottom of the main body is provided with two sets of guide grooves, and a column is slidably installed in each set of guide grooves. A transmission rod is pinned to each set of columns. A second slider is pinned to the free end of each set of transmission rods and is slidably connected to the bottom of the main body. A strong spring and a telescopic rod fixedly connected to the main body are fixedly installed on the second slider. A transmission frame fixedly connected to the buffer plate is fixedly installed on the column.

[0010] Preferably, the fall protection frame has an arc-shaped structure, and the outer side of the fall protection frame is fitted with a rubber pad for impact protection.

[0011] Preferably, the outer plate of the buffer plate is made of rubber, the bottom plate of the buffer plate is made of rigid material, and the interior of the buffer plate has a continuous honeycomb structure.

[0012] Preferably, the strong spring is located on the outside of the telescopic rod, and the two sets of transmission rods and the transmission frame form a triangular structure, with one end of the transmission frame being a triangular structure used to enhance the stability of the device.

[0013] Preferably, the shielding mechanism includes a coil spring mounted on a mounting bracket on one side, and a mounting roller fixedly connected to the free end of the coil spring is rotatably mounted between the two sets of mounting brackets. A shielding cloth is placed on the mounting roller, and a ring buckle is mounted on the shielding cloth.

[0014] On the other side, a slotted plate with through holes is welded between the mounting brackets. A wedge is welded to the bottom end of the slotted plate, and a locking slot for ring fastening is provided on the wedge.

[0015] Preferably, the through hole of the mounting roller and the slot plate are on the same horizontal plane, and the width of the through hole is greater than the thickness of the ring buckle.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention sets buffer plates and anti-fall frames around the main body, and the two are connected to each other. When the main body is impacted, the buffer plates and anti-fall frames will produce a chain reaction, thereby achieving the purpose of evenly distributing the force, reducing the pressure on each part, maximizing the buffering effect, and extending the service life of the components.

[0018] 2. When the main body is stationary, the present invention passes the shielding cloth through the slot plate and puts the ring buckle on the buckle, forming a protective screen above the main body operation panel, which can block external impacts and block a large amount of dust in the air.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figures 1-6 An impact-resistant Beidou navigation receiver includes a main body 1, with two sets of bearing seats 2 welded on both sides of the main body 1, and buffer mechanisms for protecting the main body 1 are provided on the two sets of bearing seats 2.

[0028] The buffer mechanism includes a connecting rod 4 with a pin mounted on a bearing 2. A first slider 5 is mounted on the free end of the connecting rod 4 with a pin. A buffer plate 6 is mounted 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 the characteristics of good processing performance, strong corrosion resistance, high compressive strength, and durability, and can cope with various environments. The interior of the buffer plate 6 is a continuous honeycomb structure. The honeycomb structure is the basic structure of a honeycomb. It is a structure composed of regular hexagonal single cells, with all openings facing down or facing one side, and arranged symmetrically 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 a high resistance to compressive force and can absorb the impact force from the outside, improving the impact resistance of the device.

[0029] Both ends of the buffer plate 6 are pinned to a connecting plate 7. The free end of the connecting plate 7 is pinned to a fall arrestor 8, which is connected by a pin. The fall arrestor 8 has an arc-shaped structure. The buffer plate 6 and the fall arrestor 8 deform with each other, similar to a thin-shell structure in a building, so that the force is evenly distributed on the buffer plate 6 and the fall arrestor 8, reducing the pressure on each part. The outside of the fall arrestor 8 is fitted with a rubber pad for impact protection. The rubber pad is a highly elastic polymer material with reversible deformation. It is elastic and can deform under the action of external force. After the external force is removed, it can return to its original shape. It has the same function as the buffer plate 6, which is to buffer and absorb the impact force from the outside, so as to maximize the anti-impact effect of the device.

[0030] Two sets of guide grooves 9 are provided at the bottom of the main body 1. A column 10 is slidably installed in each set of guide grooves 9. The guide grooves 9 are located on the outer wall of the bottom of the main body 1, which can reduce the weight of the various components that the main body 1 needs to bear. A transmission rod 11 is pinned to each set of columns 10. A second slider 12 is slidably connected to the bottom of the main body 1 at the free end of the two sets of transmission rods 11. A strong spring 13 and a telescopic rod 22 are fixedly installed on the second slider 12 and are fixedly connected to the main body 1. The strong spring 13 is located outside the telescopic rod 22. The strong spring 13 is a mechanical part that works by utilizing elasticity. It is made of elastic material and deforms under the action of external force. After the external force is removed, it returns to its original shape. The telescopic rod 22 guides the strong spring 13 to prevent the strong spring 13 from bending during the deformation process, which would affect the performance of the strong spring 13.

[0031] A transmission frame 14, which is fixedly connected to the buffer plate 6, is fixedly installed 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 used to enhance the stability of the device. The triangular structure makes the force evenly distributed among the three points. This distribution method can reduce the phenomenon of stress concentration, thereby improving the tensile strength and compressive strength of the material. It has stability, and is solid, firm and pressure resistant. It ensures that the transmission frame 14 will not deform and avoids affecting the impact resistance of the device.

[0032] Two sets of mounting brackets 3 are welded on both sides of the main body 1. The two sets of bearing seats 2 and mounting brackets 3 are symmetrically distributed on both sides of the main body 1, and the top of the mounting brackets 3 is higher than the main body 1. The two sets of mounting brackets 3 are equipped with shielding mechanisms to protect the operation panel of the main body 1.

[0033] The shielding mechanism includes a coil spring 18 mounted on one side of the mounting bracket 3. The coil spring 18 is a spring with a spiral in one plane. A spring is a type of spring in which material is wound into a planar spiral shape. When one end of the spring is fixed and a torque is applied to the other end, the material is subjected to bending moment and produces bending elastic deformation. As a result, the spring is torn in its own plane. The magnitude of its deformation angle is proportional to the torque. It has high torque and multi-angle torsional moment, so it is used in mechanisms that work for a long time. It has the characteristics of not being easily fatigued and self-recovering. A mounting roller 15 is rotatably mounted between the two sets of mounting brackets 3 and fixedly connected to the free end of the coil spring 18. A shielding cloth 16 is placed on the mounting roller 15. The shielding cloth 16 is made of a fireproof mesh, which has the characteristics of high strength, easy cleaning, and light weight. It will not put a weight burden on the entire device and can also resist external impacts to effectively protect the main body 1. A buckle 17 is installed on the shielding cloth 16.

[0034] On the other side, a slotted plate 19 with through holes is welded between the mounting brackets 3. The mounting roller 15 and the through holes of the slotted plate 19 are on the same horizontal plane, and the width of the through holes is greater than the thickness of the ring buckle 17. A wedge block 20 is welded to the bottom end of the slotted plate 19, and a locking slot 21 for matching connection of the ring buckle 17 is opened on the wedge block 20. Since the coil spring 18 has the ability to self-recover, it will always control the shielding cloth 16 to wrap around the mounting roller 15, thereby creating a force to control the ring buckle 17 to reset. The locking slot 21 restricts the reset path of the ring buckle 17, thereby controlling the ring buckle 17 to abut against the wedge block 20, keeping the shielding cloth 16 in a taut state and maximizing its impact resistance.

[0035] It should be noted that the specific model 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. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0036] The functional principle of this invention can be explained through the following operational methods:

[0037] When the main body 1 is impacted on the left and right sides, the buffer plate 6 will be the first to be impacted. At this time, the internal structure of the buffer plate 6 will absorb the impact force first. When the absorbed force reaches saturation, the two sets of first sliders 5 slide in opposite directions, 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. Thus, the remaining impact force will be evenly distributed to the buffer plate 6 and the anti-fall frame 8.

[0038] 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 and achieve the effect of impact resistance.

[0039] 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 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. 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 in order to absorb the impact force.

[0040] When the main body 1 is stationary, pull the ring buckle 17 and drive the shielding cloth 16 through the slot plate 19. At this time, the mounting roller 15 will rotate clockwise, and the coil spring 18 will wrap around the mounting roller 15. Then, the ring buckle 17 is fitted onto the wedge block 20, and the ring buckle 17 is controlled to cooperate with the slot 21. The coil spring 18 will always make the mounting roller 15 have a counterclockwise rotation force, so that the shielding cloth 16 will remain taut to block external dust or objects.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
