Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brackets, in particular to an inertial measurement bracket. Background Art
[0002] An inertial measurement unit is a component that measures the speed and acceleration of an object in three-dimensional space and calculates the object's motion posture. It is usually composed of multiple sensors such as velocity sensors, acceleration sensors, and gyroscopes. The inertial measurement unit on a drone can monitor the flight status of the drone in real time. Existing inertial measurement units are generally placed in a cavity on a drone, but since the motor of a drone will vibrate during flight, the inertial measurement unit inside the drone will vibrate, and the inertial measurement unit is very sensitive to vibration, which affects the accuracy of the inertial measurement unit.
[0003] To this end, the utility model provides an inertial measurement bracket. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an inertial measurement bracket, including a support, a mounting base is installed on the support, a first damping block and a plurality of telescopic rods are installed between the support and the mounting base, a second damping block is installed in the mounting base, a placement groove is opened in the second damping block, an inertial measurement device is installed in the placement groove, a top cover is installed on the upper side of the mounting base, a third damping block is fixed on the side of the top cover close to the inertial measurement device, and a cooling plate is fixed in the top cover.

[0011] Beneficial effects of the utility model: The utility model provides an inertial measurement bracket, comprising a support, a mounting seat, a first damping block, a telescopic rod, a second damping block, a top cover, a third damping block, an inertial measurement device, and a cooling plate.

DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] See also Figures 1 to 3 The utility model provides a technical solution: an inertial measurement bracket, including a support 1, a mounting base 6 is installed on the support 1, a first damping block 3 and a plurality of telescopic rods 2 are installed between the support 1 and the mounting base 6, a second damping block 4 is installed in the mounting base 6, a placement groove 13 is opened in the second damping block 4, an inertial measurement device 14 is installed in the placement groove 13, a top cover 8 is installed on the upper side of the mounting base 6, a third damping block 5 is fixed on the side of the top cover 8 close to the inertial measurement device 14, and a cooling plate 9 is fixed in the top cover 8.
[0019] In this embodiment, the upper and lower sides of the first damping block 3 are fixedly connected to the support 1 and the mounting seat 6 respectively, and the two ends of the telescopic rod 2 are fixedly connected to the support 1 and the mounting seat 6 respectively. A plurality of mounting holes 15 are opened on the support 1, and fixing bolts are installed in the mounting holes 15.
[0020] Specifically, when the device needs to be installed, the support 1 is fixed in the cavity of the drone by fixing bolts, and the fixing bolts pass through the mounting holes 15 and are threadedly installed with the drone to fix the support 1. At this time, the first damping block 3 can play a certain shock-absorbing role.
[0021] A mounting groove 7 is provided in the mounting seat 6, and the second damping block 4 is fixed in the mounting groove 7. A plurality of grooves 16 are provided on the peripheral side of the second damping block 4. A clamping block 11 is fixed on the lower side of the top cover 8. A clamping groove 12 is provided on the mounting seat 6, and the clamping groove 12 corresponds to the clamping block 11. The clamping block 11 is made of rubber material.
[0022] Specifically, after the support 1 is installed, the second damping block 4 is placed in the installation groove 7, and then the inertial measurement unit 14 is placed in the placement groove 13, and the block 11 of the top cover 8 is inserted into the slot 12. At this time, the third damping block 5 squeezes the inertial measurement unit 14 from the upper side downward, and the third damping block 5 cooperates with the second damping block 4 to completely wrap the inertial measurement unit 14, thereby further reducing the shock of the inertial measurement unit 14 and ensuring the accuracy of the inertial measurement unit 14. At the same time, compared with directly fixing the inertial measurement unit 14 with bolts or damping glue, the clamping fixation facilitates the disassembly and installation of the inertial measurement unit 14.
[0023] The cooling plate 9 includes a cooling surface and a heat dissipation surface. The cooling surface contacts the third damping block 5 . A plurality of through slots 10 are provided in the third damping block 5 . Both the third damping block 5 and the second damping block 4 contact the inertial measurement device 14 .
[0024] Specifically, when the inertial measurement unit 14 is working, it will generate heat. The cooling plate 9 is powered on to cool the cooling plate 9. The cooling surface can cool the inertial measurement unit 14, thereby preventing the inertial measurement unit 14 from having its service life reduced due to excessive temperature.
[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
