Description

Technical Field

[0001] This invention relates to the field of positioning auxiliary device technology, specifically a high-precision positioning auxiliary device for inertial navigation calibration equipment. Background Technology

[0002] Inertial navigation system (INS) calibration equipment refers to an autonomous navigation device that does not rely on external information or radiate energy externally. The positioning assistance device for INS calibration equipment is essentially a device that prevents the phone from shaking when using a mobile phone containing INS calibration components for positioning. The less the phone shakes, the higher the accuracy of the INS calibration equipment. Car phone holders are a common positioning assistance device used with INS calibration equipment.

[0003] When using existing car phone holders:

[0004] Because speed bumps are frequently installed at bends in urban roads or on highways to slow down vehicles, most existing car phone holders have clamps on both sides and the bottom of the phone holder to assist in positioning the phone used for inertial navigation calibration in a moving vehicle. When a vehicle drives over a speed bump, the phone will shake vertically due to the speed bump. Although existing car phone holders have clamps on the horizontal and bottom sides, the phone may still shake vertically due to gravity when the vehicle goes over a speed bump or on a rough road. This can cause the phone to deviate from the phone holder, potentially leading to a decrease in the accuracy of the inertial navigation calibration equipment or the risk of the phone falling, thus affecting the effectiveness of the existing car phone holder. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a high-precision positioning auxiliary device for inertial navigation calibration equipment. Through a clamping assembly, utilizing transverse clamping plates on both sides of the placement plate in the horizontal direction, a support plate at the bottom of the placement plate, and a stop block slidable from the top of the placement plate by a trigger assembly, the existing three-way clamping achieved by clamping members on both sides and the bottom is transformed into four-way clamping on both sides, the bottom, and the top.

The gear assembly includes a pinion and a large gear, which are coaxially and fixedly connected. The pinion and the large gear are rotatably connected to the mounting frame via a connecting shaft. The rack assembly includes a fixed rack and a movable rack. The fixed rack is fixedly connected inside the second limiting groove, and the movable rack is slidably connected outside the fixed rack. The fixed rack meshes with the pinion, and the movable rack meshes with the large gear. A trigger block is fixedly connected to the top of the movable rack, and the trigger block is in contact with a stop block.

[0014] Preferably, the top of the trigger block has a trapezoidal surface, and the bottom of the stop block has a trigger surface. The trapezoidal surface and the trigger surface come into contact with each other when the movable rack moves upward to the top.

[0015] Preferably, a third limiting groove is provided at the top of the first sliding groove, a locking block is fixedly connected to the top of the stop block, the locking block is slidably connected to the third limiting groove, and a spring is connected between the third limiting groove and the locking block.

[0016] Preferably, a spring is fixedly connected to the top of the first limiting groove, and the end of the spring away from the stop is fixedly connected to the bearing plate. The side of the bearing plate is connected to the transverse clamping plate on the opposite side by another spring.

[0017] Preferably, a rocker arm is rotatably connected to the top of the base, and the end of the rocker arm away from the base is fixedly connected to the bottom of the bracket.

[0021] (III) Beneficial Effects

[0022] The positioning auxiliary device for inertial navigation calibration equipment provided by the present invention has the following beneficial effects:

[0023] 1. By setting up a clamping assembly, the horizontal clamping plates that slide on both sides of the placement plate in the horizontal direction, the support plate set at the bottom of the placement plate, and the stop block set at the top of the placement plate can clamp the mobile phone used for vehicle navigation on both sides of the horizontal direction of the mobile phone placement plate, as well as at the top and bottom of the placement plate. Compared with the existing more common three-way clamping, the four-way clamping method can further clamp the mobile phone and improve the stability of the mobile phone on the vehicle mobile phone holder during vehicle movement, thereby further improving the measurement accuracy of the inertial navigation calibration equipment.

[0024] 2. By setting up an adsorption component and auxiliary components, the suction cup in the adsorption component can adsorb the base fixedly connected to the suction cup onto the vehicle's center console platform. At the same time, the auxiliary components can use the screws to drive the piston plate to slide inside the channel. The negative pressure can be used to expel excess air inside the suction cup from the ventilation openings on the outside of the channel, further ensuring a closer fit between the bottom surface of the suction cup and the surface of the vehicle's center console platform, further clamping and fixing the mobile phone, and ensuring the stability of the mobile phone.

[0025] 3. By using the spring fixedly connected between the support plate and the first limiting groove, it is easier to place the mobile phone on the placement plate by gravity. At the same time, another spring fixedly connected between the support plate and the horizontal clamping plate can use gravity and the spring to drive the horizontal clamping plates on both sides to slide towards the center line during the downward movement of the support plate, thereby clamping the mobile phone in the horizontal direction, making it more convenient to use.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] refer to Figures 1 to 10 This invention provides a high-precision positioning auxiliary device for inertial navigation calibration equipment, comprising a base 1, a rotating seat 2, a bracket 3, and a clamping assembly 4. The clamping assembly 4 includes a horizontal clamping plate 42, a bearing plate 43, and a stop block 44, which can clamp the mobile phone on both horizontal sides and vertical ends, making the phone more stable on the vehicle's mobile phone holder during vehicle movement. An improvement of this invention is the ability to utilize an adsorption assembly 6 and an auxiliary assembly 7. The adsorption assembly 6 uses a suction cup 61, and the auxiliary assembly 7 uses a piston plate 71 to better extract air from the inside of the suction cup 61 to the outside of the channel 11, creating a pressure difference between the inside and outside of the suction cup 61, thus better adsorbing the suction cup 61 onto the vehicle's central control platform.

[0039] The following describes improvements that enable the use of clamping component 4 to clamp a mobile phone performing inertial navigation calibration on a mobile phone holder.

[0040] Specifically, the clamping assembly 4 includes a placement plate 41, which is used to place the mobile phone on the bracket 3 for easier viewing by the driver. Second sliding grooves 412 are provided on both sides of the placement plate 41 in the horizontal direction. A transverse clamping plate 42 is slidably connected in each of the second sliding grooves 412. The transverse clamping plates 42 slidably connected to both sides of the placement plate 41 can clamp the sides of the mobile phone. Simultaneously, a support plate 43 slidably connected to the bottom of the placement plate 41 via a first limiting groove 414 can fix and clamp the bottom of the mobile phone containing inertial navigation calibration components. The spring 9, which is fixedly connected between the first limiting groove 414 and the support plate 43, and another spring 9, which has the same function but different specifications, and is fixedly connected between the support plate 43 and the horizontal clamping plate 42, can cause the horizontal clamping plates 42 on both sides to slide towards the mobile phone when the mobile phone is slid against the surface of the placement plate 41 towards the bottom of the placement plate 41, by utilizing the spring 9 fixedly connected between the support plates 43 on both sides and the horizontal clamping plate 42 on both sides, as well as the action of gravity. This will achieve the purpose of clamping the two sides of the mobile phone, making the clamping of the mobile phone more stable.

[0041] Meanwhile, the mounting bracket 431 fixedly connected between the two bearing plates 43 and the trigger component 8 rotatably connected to the mounting bracket 431 can trigger the trigger block 84 and the stop block 44 to come into contact with each other, so that the stop block 44 can slide out of the first slide groove 411. The sliding stop block 44 can clamp the top of the mobile phone, so that the clamping method of the mobile phone changes from the existing three-way clamping to four-way clamping, which can make the mobile phone installed on the bracket 3 more stable.

[0042] The trigger assembly 8 includes a gear assembly 81 disposed outside the mounting bracket 431. A second limiting groove 4131 is provided on the inner side wall of the mounting groove 413. A rack assembly 82 is disposed in the second limiting groove 4131. The gear assembly 81 includes a pinion 811 and a gear 812. The pinion 811 and the gear 812 are coaxially fixedly connected and rotatably connected to the mounting bracket 431 via a connecting shaft. The rack assembly 82 includes a fixed rack 821 and a movable rack 822. The fixed rack 821 is fixedly connected inside the second limiting groove 4131, and the movable rack 822 is slidably connected outside the fixed rack 821. The fixed rack 821 is meshed with the pinion 811, and the movable rack 822 is meshed with the gear 812. A trigger block 84 is fixedly connected to the top of the movable rack 822, and the trigger block 84 is in contact with the stop block 44.

[0043] By using the fixed connection between the fixed rack 821 and the second limiting groove 4131, the sliding connection between the movable rack 821 and the fixed rack 822 can further limit the movement direction of the movable rack 822, so that the movable rack 822 can always move in the vertical direction of the placement plate 41. By utilizing the mutual meshing between the fixed rack 821 and the pinion 811, when the mounting bracket 431 moves from the high point of the placement plate 41 to the low point of the placement plate 41, the pinion 811 is in the fixed rack 821. Under the action of the large gear 812, the small gear 811 rotates synchronously, and the small gear 811 and the large gear 812 rotate at the same angular velocity. The linear velocity of the large gear 812 is greater than that of the small gear 811. At this time, the rotating large gear 812 will mesh with the movable rack 822, driving the movable rack 822 to move towards the top of the placement plate 41. A trigger block 84 is fixedly connected to the top of the movable rack 822. By utilizing the trapezoidal surface 841 of the trigger block 84 on the top of the movable rack 822... The trigger block 84 contacts the trigger surface 441 on the stop block 44. When the trigger block 84 is engaged with the rack assembly 82 through the gear assembly 81, the movable rack 822 moves upward to contact the stop block 44. The trapezoidal surface 841 on the trigger block 84 continues to move upward. The trapezoidal surface 841 will drive the trigger surface 441 on the stop block 44 to slide from the inside of the first slide groove 411 on the top of the placement plate 41 to the outside of the first slide groove 411. When the mobile phone is fully inserted into the placement plate 41, the stop block 44 inside the first slide groove 411 slides out of the first slide groove 411. The stop block 44 sliding out of the first slide groove 411 can limit the vertical upward sway of the mobile phone on the placement plate 41 when the vehicle passes over speed bumps or poor road conditions. It can effectively prevent the mobile phone mounted on the bracket 3 from swaying vertically due to vehicle bumps when the vehicle passes over speed bumps or poor road conditions, and further improve the stability of the mobile phone installation.

[0044] By utilizing the sliding connection between the third limiting groove 4111 opened at the top of the first slide groove 411 and the locking block 442 fixedly connected to the top of the stop block 44, the sliding direction of the stop block 44 can be further limited, which can effectively prevent the stop block 44 from deviating or getting stuck when sliding in the third limiting groove 4111.

[0045] By using a rocker arm 14 rotatably connected to the top of the base 1, and by fixing the end of the rocker arm 14 away from the base 1 to the bottom of the bracket 3, it is easier to rotate the bracket 3 when the rocker arm 14 is rotated. The ratchet 10 hinged to the rocker arm 14 and the pawl 12 meshing with it allow the ratchet 10 and pawl 12 to mesh simultaneously when the bracket 3 is rotated, enabling the bracket 3 to rotate unidirectionally counterclockwise. The ratchet 10 and pawl 12 mesh with each other instead of using the ball joint for rotation. The unidirectional rotation between the ratchet 10 and pawl 12 allows for one-handed rotation of the bracket 3, and the unidirectional rotation also makes the phone's installation position more stable. The limiting plate 13, which is hinged to the outside of the pawl 12 by the rocker arm 14, limits the rotation angle of the pawl 12, making it more stable to rotate in one direction, so as to achieve the purpose of adjusting the angle of the phone on the bracket 3 with one hand. It is more stable and convenient to use.

[0046] By utilizing the suction cup 61 in the adsorption assembly 6, the base 1 can be adsorbed onto the vehicle's central control platform. Simultaneously, by utilizing the air chamber 62 inside the suction cup 61 and the channel 11 inside the base 1, air at the bottom of the suction cup 61 can be drawn into the channel 11. Utilizing the one-way opening of the channel 11 and the piston plate 71 slidably connected inside the channel 11 in the auxiliary assembly 7, when the piston plate 71 slides from the inside to the outside of the channel 11, the air inside the suction cup 61 will move into the inside of the channel 11 under the action of air pressure through the air chamber 62. A rotating rod 73 is rotatably connected to the piston plate 71 via a rotating shaft 72. A bolt 74 is fixedly connected to the end of the rotating rod 73 away from the piston plate 71. By using the method of turning the bolt 74, it is easier to move the piston plate 71 from the inside to the outside of the channel 11 with one hand, making it more convenient and quick to use.

[0047] By utilizing the vent 611 inside the suction cup 61, air inside the suction cup 61 can be better channeled into the air chamber 62, making it easier to expel air from the suction cup 61. This increases the adhesion between the suction cup 61 and the vehicle's central control platform, making the connection tighter and more secure. Furthermore, by setting the cross-section of the vent 611 in a trapezoidal shape with the larger diameter end facing the bottom of the suction cup 61, airflow inside the suction cup 61 can be guided from the side, further facilitating the expulsion of air. The 3M adhesive 5 fixedly attached to the outer periphery of the suction cup 61 further enhances the stability of the bracket 3, ensuring a more stable installation of the phone on the placement plate 41 when the vehicle passes over speed bumps or on rough roads, thereby improving the measurement accuracy of the inertial navigation calibration equipment.

[0048] The following is the complete working process and working principle of the above embodiments:

[0049] When using a mobile phone with inertial navigation calibration components for positioning during vehicle operation, first fix the base 1 to the top of the suction cup 61, then fix the rotating seat 2 to the top of the base 1, then install the ratchet 10 and pawl 12 on the top of the base 1, then fix the bracket 3 to the top of the rocker arm 14, and finally fix the placement plate 41 to the top of the bracket 3 by rotating it through the universal ball joint.

[0050] In use, wet the bottom of suction cup 61 with water once, then attach suction cup 61 to the center console of the vehicle and press it down firmly. Then, turn bolt 74 counterclockwise by hand. The end of bolt 74 away from channel 11 extends to the outside of channel 11. The rotation of bolt 74 drives piston plate 71 to move from the inside of channel 11 to the outside of channel 11. When piston plate 71 moves from the inside of channel 11 to the outside of channel 11, the pressure can force the air inside suction cup 61 into air chamber 62 through exhaust hole 611, and then discharge it to the outside of base 1 through the through hole opened on the outside of channel 11. This makes the bottom of suction cup 61 adhere more tightly to the center console of the vehicle. Then, apply 3M adhesive 5 to the center console of the car to make it more secure.

[0051] Slide the phone downwards along the surface of the placement plate 41. When the bottom of the phone contacts the support plate 43, due to gravity and the spring 9 fixedly connected between the support plate 43 and the horizontal clamping plate 42, the horizontal clamping plates 42 on both sides move closer to the phone as the support plate 43 moves downwards. This clamps the phone. When the support plate 43 moves to the bottom of the placement plate 41, the engagement between the fixed rack 821 and the pinion 811 causes the mounting bracket 431 to move from the high point to the low point of the placement plate 41. The pinion 811 rotates under the action of the fixed rack 821, synchronously driving the large gear 812 to rotate. The pinion 811 and the large gear 812 have the same angular velocity, but the linear velocity of the large gear 812 is greater than that of the pinion 812. The rotational linear velocity of wheel 811 causes the rotating large gear 812 to mesh with the movable rack 822, driving the movable rack 822 to move towards the top of the placement plate 41. Since a trigger block 84 is fixedly connected to the top of the movable rack 822, the trigger block 84 and the stop block 44 are in contact with each other. The trapezoidal surface 841 of the trigger block 84 on the top of the movable rack 822 is in contact with the trigger surface 441 on the stop block 44. The trapezoidal surface 841 will drive the trigger surface 441 on the stop block 44 to slide from the inside of the first slide groove 411 on the top of the placement plate 41 to the outside of the first slide groove 411. When the mobile phone is completely inserted into the placement plate 41, the stop block 44 inside the first slide groove 411 slides out of the first slide groove 411. The stop block 44 is used to achieve four-way clamping of the mobile phone, further preventing the mobile phone from shaking during vehicle operation, thereby increasing the measurement accuracy of the inertial navigation calibration equipment.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
