Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a multi-angle adjustable motion sensor. Background Technology

[0002] In the field of motion state monitoring and posture perception, motion sensors collect physical quantities such as acceleration, angular velocity, and magnetic field strength to achieve quantitative analysis of the trajectory and posture changes of objects. They are core sensing components in scenarios such as robot control, smart wearables, and industrial automation.

[0003] However, in practical applications, the installation location of existing motion sensors is easily limited by space (such as inside small devices). The narrow space may force the sensor to be installed at an angle, and the fixed structure of the sensor makes it difficult to adjust the installation angle, which is not conducive to the stable installation of the sensor in a narrow space. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a multi-angle adjustable motion sensor to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a multi-angle adjustable motion sensor, including a sensor housing for support and protection. The sensor housing contains a detection terminal for motion information detection. One end of the detection terminal is equipped with a sensitive element for signal conversion. The sensitive element is connected to a signal processing unit via a signal processing circuit. A sensor chip is located inside the signal processing unit. The housing, sensor chip, sensitive element, internal signal processing circuit, and detection terminal constitute a complete motion sensor. The surface of the sensor housing has an adjustable frame for fitting onto it. The adjustable frame contains a connecting slot for mounting and fixing. One end of the adjustable frame has a fastening connecting strip for opening and closing control. A locking block for positioning is fixedly installed inside the fastening connecting strip. A clamping block for fastening the sensor housing is threadedly connected to the middle of the adjustable frame. One end of the clamping block has an adjusting rubber strip for limiting its movement.

[0006] Preferably, one end of the sensor housing is provided with an output interface for transmitting detection signals, and the inside of the sensor housing is provided with a mounting groove for fixing the detection terminal, which is located inside the adjustment frame.

[0007] The above technical solution is adopted: the sensor housing (ABS material) has an internal mounting slot to fix the detection terminal (integrated acceleration and angular velocity sensor) to ensure stable operation of the detection element. One end output interface transmits the detection signal, which is used in conjunction with the internal signal processing circuit to quantify motion information. The detection terminal is located inside the adjustment frame, and the frame limit avoids direct impact from external forces.

[0008] Preferably, the interior of the adjusting frame is provided with a rotating groove for connecting the fastening connecting strip, and one end of the rotating groove is provided with a positioning hole for locking the locking block. The connecting groove holes are distributed on each side of the adjusting frame.

[0009] The above technical solution is adopted: the rotating groove of the adjustable frame (aluminum alloy material) is connected to the fastening strip, the positioning hole and the locking block cooperate to realize the opening and closing positioning of the frame, the connecting groove is distributed on each side of the frame to adapt to different installation positions (such as wall, equipment side), and the installation is ensured to be stable by bolt fixing. A gap is reserved on the inner side of the frame to provide space for the sensor housing to rotate.

[0010] Preferably, in any of the above embodiments, the fastening connecting strip includes a closing strip for closing the adjusting frame and a locking boss for locking. The closing strip is rotatably connected to one end of the adjusting frame, and one end of the closing strip is fixedly connected to the locking boss that engages with the adjusting frame. The locking boss has an internal groove for accommodating a locking block.

[0011] The above technical solution is adopted: the closing bar (stainless steel sheet) rotates around the rotating groove, which drives the engaging boss (nylon material) to engage with the adjusting frame. The movable groove accommodates the locking block. The mechanical engagement between the boss and the frame restricts the axial movement of the sensor housing, which is suitable for manual adjustment in narrow spaces.

[0012] Preferably, in any of the above embodiments, the locking block includes a high-strength spring for support and a locking block for locking the fastening connecting strip. The high-strength spring is fixedly installed inside the boss, and one end of the high-strength spring is fixedly installed with a locking block that moves inside the boss.

[0013] The above technical solution is adopted: a high-strength spring pushes the locking block (POM material) to be embedded in the positioning hole of the adjustment frame, generating a locking force to ensure that the closing strip does not loosen in a vibration environment. Pressing the locking block to compress the spring can unlock it, which facilitates quick adjustment of the sensor orientation.

[0014] Preferably, in any of the above embodiments, the clamping block includes a fastening screw for driving adjustment and a fastening block for fastening the sensor housing. The fastening screw is threadedly connected to the inside of the adjustment frame, and one end of the fastening screw is rotatably connected to the fastening block that fits against the surface of the sensor housing. One end of the fastening block is provided with anti-slip texture.

[0015] The above technical solution is adopted: when the fastening screw rotates, it drives the fastening block (rubber-coated metal sheet) to move radially along the adjustment frame. It fits against the sensor housing surface through anti-slip texture, so as to achieve locking at any angle and ensure the accurate positioning angle of the sensor.

[0016] Preferably, one end of the adjusting rubber strip is fixedly installed to the adjusting frame, and the other end of the adjusting rubber strip is fixedly installed to the fastening block.

[0017] The above technical solution is adopted: the adjusting strip (silicone material) connects the adjusting frame and the fastening block. As the block moves, it generates elastic deformation, which not only limits the block from being squeezed too much (protecting the shell from damage), but also compensates for the vibration gap through elasticity, ensuring long-term stability.

[0018] Loosen the locking block, flip the fastening connecting strip to open the adjustment frame, rotate the sensor housing until the detection terminal is aligned with the target direction (angle data is fed back in real time through the output interface), rotate the fastening screw of the clamping block to make the fastening pressure block clamp the housing (stop after confirming that there is no looseness), close the fastening connecting strip, and the locking block is inserted into the positioning hole under the action of the spring to complete the locking. Fix the adjustment frame to the mounting surface through the connecting slot hole to complete the sensor deployment.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. An adjustable frame is added to the motion sensor to form a fixed installation structure for the motion sensor in conjunction with the sensor housing. A fastening connecting strip that can be opened and closed is set at one end of the adjustable frame. The corresponding fastening connecting strip can be opened and closed according to the installation direction requirements of the motion sensor, and the detection terminal of the motion sensor for motion detection can be adjusted to the required direction. The detection direction of the sensor can be adjusted at multiple angles without affecting the overall size of the sensor, avoiding tilted installation of the sensor and effectively improving the convenience of installing the motion sensor in confined spaces.

[0020] 2. An adjustable clamping block is set inside the adjustment frame to clamp and fix the sensor housing. The position adjustment of the clamping block facilitates the omnidirectional rotation adjustment of the sensor housing, improves the degree of freedom of sensor adjustment, and facilitates multi-angle adjustment of the sensor.

[0026] The above technical solution is adopted: the sensor housing 1 (ABS material) has an internal mounting slot to fix the detection terminal 2 (integrated acceleration and angular velocity sensor) to ensure stable operation of the detection element. One end output interface 9 transmits the detection signal and works with the internal signal processing circuit to quantify motion information. The detection terminal 2 is located inside the adjustment frame 3, and the frame limit avoids direct impact from external forces.

[0027] Preferably, the interior of the adjusting frame 3 is provided with a rotating groove for connecting the fastening connecting strip 5, and one end of the rotating groove is provided with a positioning hole for locking the locking block 6. The connecting slot holes 4 are distributed on each side of the adjusting frame 3.

[0028] The above technical solution is adopted: the rotating groove of the adjustable frame 3 (aluminum alloy material) is connected to the fastening connecting strip 5, the positioning hole and the locking block 6 cooperate to realize the opening and closing positioning of the frame, the connecting slot hole 4 is distributed on each side of the frame to adapt to different installation positions (such as wall, equipment side), and the installation is ensured to be stable by bolt fixing. A gap is reserved on the inner side of the frame to provide space for the sensor housing 1 to rotate.

[0029] Preferably, in any of the above solutions, the fastening connecting strip 5 includes a closing strip 51 that closes the adjusting frame 3 and a locking boss 52 that engages with it. The closing strip 51 is rotatably connected to one end of the adjusting frame 3, and one end of the closing strip 51 is fixedly connected to the locking boss 52 that engages with the adjusting frame 3. The locking boss 52 has an internal groove for accommodating the locking block 6.

[0030] The above technical solution is adopted: the closing bar 51 (stainless steel sheet) rotates around the rotating groove, which drives the engaging boss 52 (nylon material) to engage with the adjusting frame 3. The movable groove accommodates the locking block 6. The mechanical engagement between the boss and the frame restricts the axial movement of the sensor housing 1, which is suitable for manual adjustment in narrow spaces.

[0032] Using the above technical solution: the high-strength spring 61 pushes the locking block 62 (POM material) into the positioning hole of the adjustment frame 3 to generate locking force, ensuring that the closing strip 51 does not loosen in the vibration environment. Pressing the locking block to compress the spring can unlock it, which facilitates quick adjustment of the sensor orientation.

[0036] The above technical solution is adopted: the adjusting strip 8 (silicone material) connects the adjusting frame 3 and the fastening block 72. It generates elastic deformation as the block moves, which not only limits the excessive compression of the block (protecting the shell from damage), but also compensates for the vibration gap through elasticity, ensuring long-term stability.

[0037] The working principle of this multi-angle adjustable motion sensor is as follows: The sensor housing 1 has a detection terminal 2 inside that detects motion information and an output interface 9 that transmits signals.
