Description

Technical Field

[0001] This utility model relates to the field of acceleration sensor installation technology, and in particular to an acceleration sensor mounting bracket. Background Technology

[0002] An accelerometer is a device used to measure the acceleration of an object. It converts physical motion into a measurable electrical signal. The motion state of an object can be inferred by measuring its acceleration. An accelerometer mounting bracket is a device used to fix and support the accelerometer.

[0003] Traditional accelerometer mounting brackets typically rely on manual adjustment and clamping to fix the sensor, which is cumbersome and prone to introducing adjustment errors, making it difficult to ensure installation consistency and accuracy. At the same time, existing clamping structures are simple and fixed, with poor adaptability to sensors of different shapes or connection interfaces, insufficient contact area, or unstable installation, making the measurement signal susceptible to interference. In addition, the shock absorption structure of traditional brackets is relatively simple, often using a single spring or a single damper, which has limited ability to absorb multidimensional vibration impacts. Especially under high-frequency or complex operating conditions, it is prone to transmitting noise, affecting the sensor signal quality. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides an accelerometer mounting bracket, which has the advantages of stable structure, convenient installation and easy fixation and adjustment of accelerometer.

[0005] The technical solution adopted by this utility model is as follows: it includes a base and a base plate, the base plate is placed inside the base, a mounting seat is fixed on the top of the base plate, a slot is provided on the top of the mounting seat, a protective shell is inserted into the slot, a limit frame is fixedly installed on the rear side of the protective shell, an adjustable clamping component is fixedly installed inside the limit frame, and a wire hole for pulling out the connecting wire is opened on the front side of the protective shell.

[0006] Preferably, in order to better protect the accelerometer and facilitate the staff to observe the working status of the accelerometer, a tempered glass is fixedly installed on the front side of the protective shell and the tempered glass is located above the wire hole.

[0007] Preferably, to reduce the impact of external vibrations on the acceleration sensor, multiple sets of springs and damping rods are fixedly installed between one side of the base and one side of the base plate, with the damping rods located inside the springs.

[0008] Preferably, to prevent accidental loosening between the mounting base and the protective shell caused by high-frequency vibration, bolts are installed between the mounting base and the protective shell.

[0009] Preferably, in order to flexibly adjust the position of the first clamping plate so as to clamp and fix accelerometers of different sizes, the adjustable clamping assembly includes a motor and a bidirectional screw with reversed threads at both ends. The motor is fixedly installed on one side of the limiting frame, the bidirectional screw is installed on the output end of the motor, and the other end of the bidirectional screw is rotatably installed on one side inside the limiting frame. A slider is slidably arranged on the outside of the bidirectional screw, and a first clamping plate is fixed on one side of the slider. The first clamping plate is located inside the protective shell.

[0010] Preferably, in order to smoothly drive the slider to slide inside the limiting frame, the slider is threadedly connected to the bidirectional screw and the slider is located inside the limiting frame.

[0011] Preferably, in order to quickly install the second clamping plate and to adjust the position of the second clamping plate according to the size of the accelerometer, the top of the first clamping plate is provided with three sets of first insertion ports.

[0012] Preferably, to facilitate quick assembly and disassembly of the second clamping plate, the second clamping plate is inserted into the first socket, and the bottom and one side of the second clamping plate are respectively provided with three sets of second sockets and slots.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5 As shown, this embodiment provides an accelerometer mounting bracket, including a base 1 and a base plate 2. The base plate 2 is placed inside the base 1, and a mounting seat 3 is fixed on the top of the base plate 2. A slot 9 is provided on the top of the mounting seat 3, and a protective shell 4 is inserted into the slot 9. A limiting frame 6 is fixedly installed on the rear side of the protective shell 4. The limiting frame 6 has a limiting effect on the adjustable clamping component 8. The adjustable clamping component 8 is fixedly installed inside the limiting frame 6. A wire hole 7 for pulling out the connecting wire is opened on the front side of the protective shell 4, so that the connecting wire of the accelerometer can be pulled out from the wire hole 7.

[0022] Tempered glass 5 is fixedly installed on the front side of the protective shell 4 and is located above the wire hole 7. The tempered glass 5 has high transparency and is impact resistant, which not only protects the accelerometer but also facilitates debugging and maintenance. Multiple sets of springs 10 and damping rods 11 are fixedly installed between one side of the base 1 and one side of the base plate 2. The damping rods 11 are located inside the springs 10 and can limit the movement of the springs 10. At the same time, the springs 10 and the damping rods 11 work together to effectively reduce the impact of external vibrations on the accelerometer. Bolts are installed between the mounting base 3 and the protective shell 4.

[0023] In practical use, the operator can place the accelerometer sensor inside the mounting base 3 and insert the bottom of the protective shell 4 into the slot 9. The adjustable clamping assembly 8 can clamp and fix accelerometer sensors of different sizes, improving the stability of the accelerometer sensor. Bolts can be used to fix the base 1 and the protective shell 4, preventing accidental loosening between the mounting base 3 and the protective shell 4 due to high-frequency vibration. Furthermore, when the accelerometer sensor needs repair or replacement, the operator can loosen the bolts to pull the protective shell 4 out of the slot 9, facilitating access to the accelerometer sensor inside the protective shell 4. The system is designed for disassembly and assembly. Simultaneously, operators can observe the status of the accelerometer through the tempered glass 5, facilitating the adjustment of the accelerometer and making it more convenient to use. Afterward, the base 1 is fixed again with bolts. Multiple sets of springs 10 and built-in damping rods 11 set between the base 1 and the base plate 2 form a composite buffer structure. The springs 10 and damping rods 11 work together to effectively absorb multidimensional vibration and impact, reduce signal noise, improve the accuracy of the accelerometer measurement results, and fully consider various complex situations in actual use, greatly improving the overall performance of the accelerometer mounting bracket.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the adjustable clamping assembly 8 includes a motor 801 and a bidirectional screw 802 with reversed threads at both ends. The motor 801 is fixedly mounted on one side of the limiting frame 6, and the bidirectional screw 802 is mounted on the output end of the motor 801. The other end of the bidirectional screw 802 is rotatably mounted inside the limiting frame 6. A slider 803 is slidably mounted on the outside of the bidirectional screw 802. The top and bottom of the slider 803 are in contact with the top inner wall and bottom inner wall of the limiting frame 6, respectively. The limiting frame 6 has a limiting effect on the slider 803, allowing the slider 803 to move on the bidirectional screw 802 instead of rotating. A first clamping plate 804 is fixed to one side of the slider 803. The first clamping plate 804 is located inside the protective shell 4. The slider 803 is threadedly connected to the bidirectional screw 802 and is located inside the limiting frame 6. The top of the first clamping plate 804 has three sets of first insertion ports 805. The second clamping plate 806 is inserted into the first insertion port 805. The bottom and one side of the second clamping plate 806 have three sets of second insertion ports 807 and slots 808 respectively. The two first clamping plates 804 and one second clamping plate 806 work together to clamp and fix accelerometers of different sizes, improving the stability of the accelerometer. The slots 808 facilitate the user to quickly install and remove the second clamping plate 806.

[0025] In use, the operator can start the motor 801 to drive the bidirectional screw 802 to rotate precisely. Since the threads at both ends of the bidirectional screw 802 are in opposite directions, and the slider 803 is connected to the bidirectional screw 802 by threads, the two sliders 803 will move inward or outward respectively according to the direction of the threads and the direction of rotation during the rotation of the bidirectional screw 802. This makes the movement of the sliders 803 very smooth and controllable. As the sliders 803 move, the first clamping plate 804 fixed on one side of the slider 803 will also move accordingly, thereby achieving precise clamping and fixing of the accelerometer. In addition, the top of the first clamping plate 804 is designed with three sets of first sockets 805. The first sockets 805 can not only nest the second clamping plate 806 with the second socket 807 and the slot 808, but also flexibly adjust the position of the second clamping plate 806 according to actual needs. The modular expansion structure greatly improves the flexibility and adaptability of the clamping components, enabling the mounting bracket to easily cope with accelerometers of different sizes and shapes.
