Technical Field

[0001] This utility model relates to the technical field of vehicle GPS antenna mounting brackets, and in particular to a differential GPS mobile terminal antenna mounting bracket. Background Technology

[0002] To improve portability and achieve high-precision differential positioning and high-precision heading positioning, the mushroom-shaped antenna, radio, controller, Bluetooth module, and battery are typically mounted together on a bracket, which is then fixed to the vehicle body. This bracket is usually rigidly connected to the vehicle body, lacking shock absorption, which can easily damage the electronic equipment and requires improvement. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a differential GPS mobile antenna mounting bracket.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A differential GPS mobile antenna mounting bracket includes a main support, which includes a crossbeam for mounting electronic equipment and a longitudinal beam fixed to the middle of the crossbeam. A sleeve is fitted over the longitudinal beam, and a plurality of circular shock-absorbing rubber blocks are fitted along the upper edge of the longitudinal beam inside the sleeve. Anti-detachment sleeves are fitted on the upper and lower sides of each shock-absorbing rubber block on the longitudinal beam. The anti-detachment sleeves are fixed to the longitudinal beam by bolts and nuts. The shock-absorbing rubber block is sandwiched between two opposite anti-detachment sleeves. An annular groove coaxial with itself is provided on the outer circumference of the shock-absorbing rubber block. A retaining ring is fixed to the inner wall of the sleeve corresponding to each of the retaining grooves, and a plurality of retaining rings are respectively engaged in the plurality of retaining grooves.

[0006] Furthermore, the sleeve is formed by joining two arc-shaped plates with a semi-circular cross-section. The inner wall of the arc-shaped plate is provided with a fan-shaped flange corresponding to the slot. The two opposing flanges form the retaining ring. A mounting plate is fixed to the bottom end of the arc-shaped plate, and a mounting hole is provided on the mounting plate.

[0007] Furthermore, connecting plates are fixed to both long straight edges of the arc-shaped plate. When two arc-shaped plates are joined together, the connecting plates on the two arc-shaped plates are in contact with each other, and the two in contact connecting plates are fixed together by a number of bolts and nuts.

[0008] Furthermore, a rubber block clamp is fixed to the side of the anti-detachment sleeve near the shock-absorbing rubber block. The size of the rubber block clamp corresponds to the size of the shock-absorbing rubber block, and the upper and lower end faces of the shock-absorbing rubber block are respectively tightly fitted with one of the rubber block clamps.

[0009] Furthermore, a reinforcing rod is fixedly connected between the crossbeam and the longitudinal beam.

[0010] The beneficial effects of this utility model are as follows: the sleeve is used to rigidly connect the vehicle body, and the longitudinal beam is clamped in the sleeve by a number of shock-absorbing rubber blocks, which avoids the rigid connection between the main support and the vehicle body. The shock-absorbing rubber blocks have the effect of lateral and longitudinal shock absorption, which can effectively reduce the vibration of the vehicle body to the main support and effectively prevent damage to electronic equipment installed on the main support.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] like Figures 1-5As shown, a differential GPS mobile antenna mounting bracket includes a main bracket, which comprises a crossbeam 1 and a longitudinal beam 2. The top of the longitudinal beam 2 is fixed to the middle of the crossbeam 1, making the main bracket T-shaped. A mushroom-shaped antenna 3 is mounted at each end of the crossbeam 1 along its length. A controller 4 is mounted in the middle of the crossbeam 1, and the controller 4 integrates an IMU inertial navigation module and a Bluetooth module. A radio 5 is also mounted on the crossbeam 1. A mounting platform 21 is fixed to the middle of the longitudinal beam 2, and a battery 6 is mounted on the mounting platform 21. The mushroom-shaped antennas 3 and the controller 4 are also included. All radios 5 are electrically connected to batteries 6. The lower section of the longitudinal beam 2 is fitted with a sleeve. Three circular shock-absorbing rubber blocks 7 are fitted on the upper edge of the longitudinal beam 2 inside the sleeve. Anti-detachment sleeves 8 are fitted on the upper and lower sides of each shock-absorbing rubber block 7 on the longitudinal beam 2. The anti-detachment sleeves 8 are fixed to the longitudinal beam 2 by bolts and nuts. The shock-absorbing rubber block 7 is sandwiched between two opposite anti-detachment sleeves 8. The outer circumference of the shock-absorbing rubber block 7 is provided with a coaxial annular groove 71. The inner wall of the sleeve is fixed with a retaining ring corresponding to each groove 71. The three retaining rings are respectively locked in the three grooves 71.

[0019] In actual use, the sleeve is rigidly connected to the vehicle body. With the action of the damping rubber block 7, the rigid connection between the main support and the vehicle body can be effectively avoided. The damping rubber block 7 has both lateral and longitudinal damping effects, which can effectively reduce the vibration of the vehicle body to the main support and prevent damage to the electronic equipment installed on the main support.

[0020] The two mushroom-shaped antennas on the crossbeam 1 measure their respective latitude and longitude information and correct their position using the latitude and longitude information received from the base station. The controller 4, integrating an IMU inertial navigation module, is installed at the midpoint between mushroom-shaped antennas 3A and 3B. The average latitude and longitude of mushroom-shaped antennas A and B is the latitude and longitude of the midpoint. Connecting points A and B in a line allows for the measurement of their heading. The controller 4 transmits the current latitude, longitude, and heading information to external devices such as laptops or mobile phones via Bluetooth. Furthermore, the controller 4 is equipped with an IMU module, which can be used to quickly measure pitch and roll attitude information and transmit it to external devices via Bluetooth. Battery 6 powers all modules of the system.

[0021] In this embodiment, the sleeve is formed by joining two semi-circular arc plates 9 together. A connecting plate 91 is fixed to each of the two long straight edges of the arc plate 9. The connecting plates 91 on the two arc plates 9 fit together and are fixed together by several bolts and nuts. This arrangement facilitates the installation of the longitudinal beam 2 inside the sleeve. The inner wall of the arc plate 9 is provided with a fan-shaped flange 92 corresponding to the slot 71. Two opposing flanges 92 form the retaining ring. A mounting plate 93 is fixed to the bottom end of the arc plate 9. The mounting plate 93 has a mounting hole 931, which allows the sleeve to be quickly fixed to the vehicle body.

[0022] In this embodiment, a rubber block clamping plate 81 is fixedly connected to the side of the anti-detachment sleeve 8 near the shock-absorbing rubber block 7. The size of the rubber block clamping plate 81 corresponds to the size of the shock-absorbing rubber block 7. The upper and lower end faces of the shock-absorbing rubber block 7 are respectively tightly fitted with a rubber block clamping plate 81. The rubber block clamping plate 81 can effectively fix the shock-absorbing rubber block 7.

[0023] In this embodiment, a reinforcing rod 10 is fixedly connected between the crossbeam 1 and the longitudinal beam 2, which improves the strength of the entire main support.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
