Description

Technical Field

[0001] The present invention relates to the technical field of satellite terminal equipment, in particular to an anti-resonance vehicle-mounted Beidou satellite positioning terminal. Background Art

[0002] The vehicle-mounted Beidou satellite positioning terminal is a very important auxiliary equipment for people in the process of driving a car. It plays a very important role in the driver's driving and travel, and provides a very convenient service for people to drive and travel. The existing vehicle-mounted Beidou satellite positioning terminal has certain disadvantages when in use. First, the vibration of the car's operation will be directly transmitted to the terminal, which has certain inconveniences. Secondly, there is no good defense mechanism against the influence of external vibration, which is not conducive to people's use.

[0003] When a car encounters a bumpy road during driving, the body of the car will vibrate. The vibration will affect the satellite positioning device, causing damage to the device during the vibration, thereby affecting the normal positioning of the satellite positioning terminal. In order to improve the shock resistance, the outer shell of the positioning terminal is usually relatively closed, which will affect the heat dissipation effect. After the terminal is used for a long time, the heat generated by the internal electronic components may not be dissipated in time, resulting in temperature rise. High temperature may affect the performance of the chip, reduce the accuracy and stability of positioning, and may even damage the electronic components. Summary of the invention

The T-shaped driving plate is slidably connected to the L-shaped transmission air pipe. The end of the T-shaped driving plate extends outside the L-shaped transmission air pipe.

[0015] The present invention has the following beneficial effects:

[0016] (1) For the anti-resonance vehicle-mounted Beidou satellite positioning terminal of the present invention, when the vehicle is driving on the highway, since the road surface is relatively flat, the flat road surface will reduce the vibration of the vehicle. At this time, since the vehicle speed on the highway is relatively fast, the air flow will enter the outer shell from the air inlet hole. After the air flow enters the outer shell, it will pass through several transmission fan blades. The transmission fan blades will rotate under the action of the air flow. The transmission fan blades will drive the reciprocating screw to rotate. The reciprocating screw will drive the cleaning plate to rotate. The cleaning plate will clean the dust and impurities remaining on the inner surface of the air inlet hole, avoiding the influence of dust and impurities on the air intake effect of the air inlet hole. The rotation of the reciprocating screw will drive the internally threaded push block to rotate. The internally threaded push block will move in a direction away from the cleaning plate. The internally threaded push block will contact the movable plate and push the movable plate to move. The movable plate will move closer to the positioning device. At this time, the heat dissipation hole will undergo compressive deformation. During this process, the air in the hollow cylinder will be compressed. The gas will pass through the heat dissipation holes on the positioning device, and then the gas will pass through the exhaust round hole and push the U-shaped circular plate to move in a direction away from the hollow cylinder. At this time, the exhaust groove will undergo tensile deformation. After the exhaust groove on the U-shaped circular plate exposes the hollow U-shaped cylinder, the gas in the hollow cylinder will be discharged. During the process of gas discharge, the heat generated by the positioning device will be taken away, thereby cooling the positioning device;

[0017] (2) In the anti-resonance vehicle-mounted Beidou satellite positioning terminal of the present invention, under the reciprocating action of the reciprocating screw, the internal thread push block will return. Correspondingly, during the process of the internal thread push block leaving the positioning device, the movable spring and the exhaust groove will drive the positioning device and the C-shaped circular plate to reset under the action of elastic force. Since the inside of the hollow cylinder is in a negative pressure state, under the action of atmospheric pressure, air will enter the annular groove through the air inlet hole. The air will push the annular sealing plate to move towards the positioning device. At this time, the sealing spring undergoes a tensile deformation. When the annular sealing plate leaves the annular groove, the outside air will enter the hollow cylinder through the gap between the annular sealing plate and the annular groove for air filling, providing conditions for the heat dissipation of the positioning device next time. When the vehicle stops running, the C-shaped circular plate and the movable plate will seal the hollow cylinder to prevent moisture and dust in the air from entering the hollow cylinder and damaging the electronic components in the positioning device;

[0018] (3) In the anti-resonance vehicle-mounted Beidou satellite positioning terminal of the present invention, when the vehicle is driving on a bumpy road section, the body will be severely shaken. At this time, the outer shell will vibrate, and the outer shell will drive the hollow cylinder to vibrate. During the up and down vibration of the hollow cylinder, it will drive the two T-shaped plates to vibrate. The upward vibration force of the T-shaped plate will be absorbed by the shock-absorbing spring. When the T-shaped plate vibrates downward, it will contact and drive the transmission rectangular plate to descend. The air at the bottom of the transmission rectangular plate and the transmission spring will absorb the vibration force to play a buffering role. During the braking and accelerating processes of the vehicle, the hollow cylinder will sway back and forth. The force generated by the swaying will drive the hollow cylinder to rotate left and right under the action of the two C-shaped round rods. When the hollow cylinder rotates, it will drive the semi-circular block to rotate. The rotating force of the semi-circular block will be absorbed by the limit spring, realizing the multi-directional vibration buffering of the hollow cylinder and reducing the vibration damage of the positioning device during vehicle movement;

[0019] (4) In the anti-resonance vehicle-mounted Beidou satellite positioning terminal of the present invention, since the vehicle travels slowly on a bumpy road section and the generated wind force is not enough to rotate the reciprocating screw, when the transmission rectangular plate descends, it will squeeze the gas in the transmission air box. The gas will pass through the L-shaped transmission air pipe and the L-shaped transmission air box to push the T-shaped driving plate to move towards the movable plate. At this time, the driving spring undergoes a tensile deformation. When the T-shaped driving plate moves, it will contact and push the movable plate to slide into the hollow cylinder. As described above, when the movable plate moves, the same heat dissipation effect will be generated. At this time, the more bumpy the road section, the greater the moving amplitude of the T-shaped driving plate, and correspondingly, the better the heat dissipation effect on the positioning device.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is an anti-resonance vehicle-mounted Beidou satellite positioning terminal, including an outer shell 1. A plurality of air inlet holes 2 are opened on the front surface of the outer shell 1, and a plurality of air outlet holes 3 are opened on the back surface of the outer shell 1. It further includes:

[0034] A heat dissipation mechanism 4, the heat dissipation mechanism 4 includes a reciprocating screw 401 rotatably installed on the outer shell 1. The end of the reciprocating screw 401 extends into the outer shell 1. Two cleaning plates 402 are fixedly installed on the outer wall of the reciprocating screw 401. Both cleaning plates 402 are in contact with the outer shell 1. A plurality of driving fan blades 403 are fixedly installed on the outer wall of the reciprocating screw 401. An internal thread push block 404 is threadedly sleeved on the reciprocating screw 401. Two limit sliding rods 406 are fixedly installed on the outer wall of the internal thread push block 404. Limit strip grooves 405 are respectively opened on the left inner wall and the right inner wall of the outer shell 1. The mutually remote ends of the two limit sliding rods 406 respectively extend into the two limit strip grooves 405 and are respectively slidably connected to the two limit strip grooves 405.

[0035] As Figure 3 and Figure 5 As shown in the figure, an active mechanism 5 is arranged inside the housing 1. The active mechanism 5 includes a hollow cylinder 501 arranged inside the housing 1. A positioning device 502 is fixedly installed inside the hollow cylinder 501. A number of heat dissipation holes 503 are provided on the positioning device 502. A movable spring 504 is fixedly installed on the front surface of the positioning device 502. The front end of the movable spring 504 is fixedly installed with a movable plate 505. The movable plate 505 is slidably connected to the hollow cylinder 501. The end of the hollow cylinder 501 is fixedly installed with a hollow U-shaped cylinder 506. The hollow U-shaped cylinder 506 communicates with the hollow cylinder 501.

[0036] The internal thread push block 404 will contact the movable plate 505 and push the movable plate 505 to move. The movable plate 505 moves closer to the positioning device 502. At this time, the heat dissipation holes 503 undergo compressive deformation. During this process, the air inside the hollow cylinder 501 will be compressed, and the gas will pass through the heat dissipation holes 503 on the positioning device 502.

[0037] As Figure 6 shown in the figure, a sealing mechanism 6 is arranged on the movable plate 505. The sealing mechanism 6 includes an annular groove 601 opened on the back surface of the movable plate 505. A number of air injection holes 602 are opened on the front inner wall of the annular groove 601. A number of sealing springs 603 are fixedly installed on the front inner wall of the annular groove 601. The ends of the number of sealing springs 603 are fixedly installed with an annular sealing plate 604. The annular sealing plate 604 is slidably connected to the annular groove 601.

[0038] Since the inside of the hollow cylinder 501 is in a negative pressure state, under the action of the atmospheric pressure, air will enter the annular groove 601 through the air injection holes 602. The air will push the annular sealing plate 604 to move closer to the positioning device 502. At this time, the sealing springs 603 undergo tensile deformation. When the annular sealing plate 604 leaves the annular groove 601, the outside air will enter the hollow cylinder 501 through the gap between the annular sealing plate 604 and the annular groove 601 to fill the air, providing conditions for the heat dissipation of the positioning device 502 next time.

[0039] As Figure 5 shown in the figure, a number of exhaust round holes 605 are opened on the hollow U-shaped cylinder 506. An exhaust spring 606 is fixedly installed on the back inner wall of the hollow U-shaped cylinder 506. The end of the exhaust spring 606 is fixedly installed with a U-shaped circular plate 607. The U-shaped circular plate 607 is slidably connected to the hollow U-shaped cylinder 506. A number of exhaust grooves 608 are opened on the U-shaped circular plate 607.

[0040] The gas will pass through the exhaust round hole 605 and push the C-shaped round plate 607 to move away from the hollow cylinder 501. At this time, the exhaust groove 608 undergoes tensile deformation. After the exhaust groove 608 on the C-shaped round plate 607 exposes the hollow C-shaped cylinder 506, the gas in the hollow cylinder 501 will be discharged. During the process of gas discharge, the heat generated by the positioning device 502 will be taken away, thereby cooling the positioning device 502.

[0041] As Figure 7 shown, a shock-absorbing mechanism 7 is provided inside the housing 1. The shock-absorbing mechanism 7 includes two rectangular rods 701 fixedly installed inside the housing 1. T-shaped plates 702 are respectively sleeved on the two rectangular rods 701 in a sliding manner. Shock-absorbing springs 703 are respectively sleeved on the two rectangular rods 701. The top ends of the two shock-absorbing springs 703 are fixedly connected to the housing 1, and the bottom ends of the two shock-absorbing springs 703 are respectively fixedly connected to the two T-shaped plates 702. Two arc-shaped hollow plates 704 are fixedly installed on the outer wall of the hollow cylinder 501. C-shaped round rods 705 are respectively fixedly installed on one side of the two T-shaped plates 702 close to each other. The two C-shaped round rods 705 respectively penetrate through the two arc-shaped hollow plates 704, and the two C-shaped round rods 705 are respectively slidably connected to the two arc-shaped hollow plates 704.

[0042] During the up-and-down vibration of the hollow cylinder 501, the two T-shaped plates 702 will be driven to vibrate, and the upward vibration force of the T-shaped plate 702 will be absorbed by the shock-absorbing spring 703.

[0043] As Figure 7 shown, a semi-circular block 706 is provided on the hollow cylinder 501. An arc-shaped rod 707 is fixedly installed on one side of the two T-shaped plates 702 close to each other. The arc-shaped rod 707 penetrates through the semi-circular block 706 and is slidably connected to the semi-circular block 706. Two limiting springs 708 are sleeved on the arc-shaped rod 707. The ends of the two limiting springs 708 away from each other are respectively fixedly connected to the two T-shaped plates 702, and the ends of the two limiting springs 708 close to each other are both fixedly connected to the semi-circular block 706.

[0044] The force generated by the晃动 will drive the hollow cylinder 501 to rotate left and right under the action of the two C-shaped round rods 705. When the hollow cylinder 501 rotates, it will drive the semi-circular block 706 to rotate, and the force for the semi-circular block 706 to rotate will be absorbed by the limiting spring 708, realizing the multi-directional vibration buffering of the hollow cylinder 501 and reducing the vibration damage suffered by the positioning device 502 during vehicle movement.

[0045] As Figure 8 It should be noted that there is an unclear word "晃动" in the original text. I translated it as "晃动" directly. You may need to check and correct it according to the actual situation.As shown, a transmission mechanism 8 is arranged in the outer shell 1, and the transmission mechanism 8 includes two transmission air boxes 801 fixedly mounted on the inner wall at the bottom of the outer shell 1, and T-shaped air cavities 802 are respectively opened in the two transmission air boxes 801, and transmission springs 803 are respectively fixedly mounted on the inner walls at the bottom of the two T-shaped air cavities 802, and transmission rectangular plates 804 are respectively fixedly mounted on the tops of the two transmission springs 803, and the two transmission rectangular plates 804 are respectively slidably connected to the two T-shaped air cavities 802.

[0046] When the T-shaped plate 702 vibrates downward, it will contact and drive the transmission rectangular plate 804 downward, and the air at the bottom of the transmission rectangular plate 804 and the transmission spring 803 will absorb the force of its vibration and play a buffering role.

[0047] like Figure 3 As shown, an L-shaped transmission air pipe 805 is fixedly installed on the side where the two transmission air boxes 801 are close to each other, and an L-shaped transmission air box 806 is fixedly installed on the bottom inner wall of the outer shell 1. The close ends of the two L-shaped transmission air pipes 805 are communicated with the L-shaped transmission air box 806. A driving spring 807 is fixedly installed on the front inner wall of the L-shaped transmission air box 806, and a T-shaped driving plate 808 is fixedly installed on the end of the driving spring 807. The T-shaped driving plate 808 is slidably connected to the L-shaped transmission air pipe 805, and the end of the T-shaped driving plate 808 extends to the outside of the L-shaped transmission air pipe 805.

[0048] The gas will pass through the L-shaped transmission air pipe 805 and the L-shaped transmission air box 806 to push the T-shaped driving plate 808 to move towards the direction close to the movable plate 505. At this time, the driving spring 807 will be stretched and deformed. When the T-shaped driving plate 808 moves, it will contact and push the movable plate 505 to slide into the hollow cylinder 501. At the same time, the same heat dissipation effect will be produced when the movable plate 505 moves. At this time, the bumpier the road section, the greater the movement amplitude of the T-shaped driving plate 808 will be, and the corresponding heat dissipation effect on the positioning device 502 will be better.

[0049] When in use, when the vehicle is driving on the highway, due to the relatively flat road surface, the flat road surface will reduce the vibration of the vehicle. At this time, since the vehicle is driving at a relatively high speed on the highway, the airflow will enter the housing 1 through the air inlet 2. After the airflow enters the housing 1, it will pass through several drive fan blades 403. The drive fan blades 403 will rotate under the action of the airflow. The drive fan blades 403 will drive the reciprocating screw 401 to rotate. The reciprocating screw 401 will drive the cleaning plate 402 to rotate. The cleaning plate 402 will clean the dust and impurities remaining near the air inlet 2 to prevent the dust and impurities from affecting the air intake effect of the air inlet 2. The rotation of the reciprocating screw 401 will drive the internally threaded push block 404 to rotate. The internally threaded push block 404 will move in a direction away from the cleaning plate 402. The internally threaded push block 404 will contact the movable plate 505 and push the movable plate 505 to move. The movable plate 505 will move closer to the positioning device 502. At this time, the heat dissipation holes 503 will undergo compressive deformation. During this process, the air in the hollow cylinder 501 will be compressed. The gas will pass through the heat dissipation holes 503 on the positioning device 502, and then the gas will pass through the exhaust round hole 605 and push the U-shaped circular plate 607 to move in a direction away from the hollow cylinder 501. At this time, the exhaust groove 608 will undergo tensile deformation. After the exhaust groove 608 on the U-shaped circular plate 607 exposes the hollow U-shaped cylinder 506, the air in the hollow cylinder 501 will be discharged. During the discharge of the gas, the heat generated by the positioning device 502 will be taken away; under the reciprocating action of the reciprocating screw 401, the internally threaded push block 404 will return. Correspondingly, during the process of the internally threaded push block 404 leaving the positioning device 502, the movable spring 504 and the exhaust groove 608 will drive the positioning device 502 and the U-shaped circular plate 607 to reset under the action of the elastic force. Since the inside of the hollow cylinder 501 is in a negative pressure state, under the action of the atmospheric pressure, the air will enter the annular groove 601 through the air delivery hole 602. The air will push the annular sealing plate 604 to move in a direction closer to the positioning device 502. At this time, the sealing spring 603 will undergo tensile deformation. When the annular sealing plate 604 leaves the annular groove 601, the outside air will enter the hollow cylinder 501 through the gap between the annular sealing plate 604 and the annular groove 601 for air filling to provide conditions for the heat dissipation of the positioning device 502 next time. When the vehicle stops running, the U-shaped circular plate 607 and the movable plate 505 will make the hollow cylinder 501 sealed;

[0050] When the vehicle is driving on a bumpy road section, the body will be severely shaken. At this time, the outer shell 1 will vibrate, and the outer shell 1 will drive the hollow cylinder 501 to vibrate. During the up and down vibration of the hollow cylinder 501, it will drive the two T-shaped plates 702 to vibrate. The upward vibration force of the T-shaped plate 702 will be absorbed by the shock-absorbing spring 703. When the T-shaped plate 702 vibrates downward, it will contact and drive the transmission rectangular plate 804 to descend. The air at the bottom of the transmission rectangular plate 804 and the transmission spring 803 will absorb the vibration force to play a buffering role. During the braking and accelerating processes of the vehicle, the hollow cylinder 501 will shake back and forth. The force generated by the shaking will drive the hollow cylinder 501 to rotate left and right under the action of the two C-shaped round rods 705. When the hollow cylinder 501 rotates, it will drive the semi-circular block 706 to rotate. The force generated by the rotation of the semi-circular block 706 will be absorbed by the limit spring 708, realizing the multi-directional vibration buffering of the hollow cylinder 501; because the vehicle travels slowly on the bumpy road section, the generated wind force is not enough to make the reciprocating screw 401 rotate. During the descent of the transmission rectangular plate 804, it will squeeze the gas in the transmission air box 801. The gas will pass through the L-shaped transmission air pipe 805 and the L-shaped transmission air box 806 to push the T-shaped driving plate 808 to move in the direction close to the movable plate 505. At this time, the driving spring 807 undergoes a tensile deformation. When the T-shaped driving plate 808 moves, it will contact and push the movable plate 505 to slide into the hollow cylinder 501. At the same time, when the movable plate 505 moves, the same heat dissipation effect will be generated. At this time, the more bumpy the road section is, the greater the moving amplitude of the T-shaped driving plate 808 will be.
