Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor technology, specifically to a wireless tilt sensor. Background Technology
[0002] In existing tilt detection devices, most use a combination of a fixed electrolyte module and a single tilt sensor for angle measurement. However, in practical applications, due to complex installation environments, external vibrations, and limited space, the reference angles of the electrolyte module and the tilt sensor are often difficult to be perfectly aligned, leading to a decrease in measurement accuracy. In addition, traditional devices often rely on rotary adjustment structures during angle adjustment, which involve many components and complex assembly, making them prone to uneven mechanical clearances, wear, and low repeatability accuracy. Furthermore, in order to ensure the reasonable layout of external interfaces such as power ports and communication antennas, existing designs often result in lengthy internal wiring, increasing signal attenuation and interference risks, and affecting overall protection performance.
[0003] To overcome the above problems, the tilt sensor proposed in this application divides the internal space of the device into an electrical control area and a mechanical adjustment area. The PCB circuit board and lithium battery are centrally arranged in the electrical control area, and the mechanical adjustment area is equipped with a mounting frame and a fixed angle adjustment frame. A lead screw passes through the front end of the adjustment frame, and symmetrically arranged knurled nuts are fitted on the lead screw. The linear movement of the nuts drives the electrolyte receiving shaft to generate micro-displacement, thereby realizing the fine adjustment of the electrolyte module's angle. This structure eliminates the need for the adjustment frame itself to rotate, simplifies the motion chain, and improves the fine adjustment accuracy and repeatability. Utility Model Content

Detailed Implementation
[0018] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] In the description of this utility model, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0020] This application proposes a wireless tilt sensor, which has the following features:
[0021] For reference Figure 1-3 This application mainly consists of a housing 1, a mounting frame 3, an angle adjustment bracket 6, a lead screw 7, a knurled nut 8, and an electrolyte receiving shaft 9 that move relative to each other. By adjusting the angle bracket, the electrolyte detection direction is made consistent with the gravity direction or flow direction, and at the same time, the reference angle of the tilt sensing module is set to the current attitude, so as to realize the coordinate alignment of the two sensing systems.
[0022] For reference Figure 1-3 The surface of this device is mainly composed of an outer shell 1 and shell covers 2 installed on both sides of it. The shell covers 2 are firmly connected to the outer shell 1 by screws to form a closed protective structure. Sealing grooves 4 are provided on both outer surfaces of the outer shell 1, and sealing gaskets 5 that are adapted to them are embedded in the sealing grooves 4.
[0023] Through this structural design, a reliable sealing interface is formed at the junction of the housing cover 2 and the outer shell 1, which can effectively block the intrusion of external moisture, dust and impurities, and ensure that the internal unit is in a stable sealed environment.
[0024] For reference Figure 1-3 The inner cavity of the outer casing 1 is divided into two independent functional areas, left and right. One side is used to install electrical control components, and the other side is used to install the angle adjustment mechanism.
[0025] The electrical control components include a PCB circuit board 12 and a lithium battery 13, used for power supply and signal processing. The other side features a mechanical adjustment unit with a mounting frame 3 fixed inside. A support shaft 31 is mounted on the inner wall of one end of the mounting frame 3, and the support shaft 31 is connected to an angle adjustment bracket 6 via screws. A lead screw 7 passes through the front end of the angle adjustment bracket 6, and two knurled nuts 8 are fitted onto the outer surface of the lead screw 7 for angle locking and fine-tuning control. An electrolyte receiving shaft 9 is also located inside the mounting frame 3, away from the support shaft 31. This receiving shaft is positioned opposite the other end of the angle adjustment bracket 6, and its end facing the lead screw 7 has a triangular connecting surface structure. When the knurled nuts 8 are rotated, the two knurled nuts 8 move linearly in opposite directions on the lead screw 7, thereby driving the electrolyte receiving shaft 9 located between the two nuts to produce a small displacement along the lead screw direction.
[0026] Through the above structural design, angle adjustment can be completed solely through the linear engagement of the knurled nut 8 and the lead screw 7, eliminating the need for the angle adjustment frame to rotate. This avoids the structural complexity and assembly errors associated with rotating components, while also ensuring the stability and repeatability of the adjustment process. This mechanism enables precise attitude control of the electrolyte module within a limited space, ensuring that the electrolyte detection surface remains aligned with the tilt sensing reference surface, thereby improving the accuracy of measurement data and the reliability of the device.
[0027] For reference Figure 1-3 A charging port 10 is provided on one side of the outer casing 1 to provide power to the internal lithium battery. A glue rod antenna 11 is provided on the same side of the outer casing 1 as the charging port 10, and the glue rod antenna 11 is electrically connected to the external communication module. By arranging the charging port 10 and the glue rod antenna 11 on the same side of the outer casing, the power interface and signal interface are centrally distributed, which facilitates installation and maintenance. At the same time, the connection distance between the PCB circuit board 12 and various functional components can be shortened during internal wiring, reducing signal loss and electromagnetic interference.
[0028] Furthermore, the angle adjustment bracket 6 is composed of two parts: a mounting shaft 61 and a U-shaped shaft 62, which are integrally formed. The lead screw 7 operates at the opening of the U-shaped shaft 62.
[0029] Furthermore, one side of the U-shaped shaft 62 extends outward to form the mounting shaft 61. The mounting shaft 61 and the U-shaped shaft 62 maintain a smooth transition, making the mounting surface of the overall structure flatter and avoiding the abrupt appearance and assembly interference problems caused by traditional protruding support structures. Threaded holes are provided at corresponding positions on the mounting shaft 61 and the support shaft 31, and the connection is secured with screws to ensure reliable positioning and uniform force distribution of the angle adjustment bracket 6 within the mounting frame 3.
[0030] For reference Figure 1-3 The mounting frame 3 has an inner groove 32 at the connection position on both sides of the U-shaped shaft 62. This inner groove 32 causes a gap to be formed between the mounting frame 3 and the U-shaped shaft 62. This gap can buffer local stress and disperse concentrated stress caused by installation, angle fine adjustment or vibration during assembly and use, thereby reducing structural wear and improving mechanical stability and durability.
[0031] In this invention, the working steps of the device are as follows:
[0032] 1. First, fix the angle adjustment bracket 6 together with the U-shaped shaft 62 to the support shaft 31 inside the mounting frame 3 via the mounting shaft 61, and tighten it with screws; ensure that the U-shaped shaft 62 is embedded in the inner groove 32 of the mounting frame 3 to form a small gap to provide buffer and stress distribution space; at the same time, install the electrical control components (PCB circuit board 12, lithium battery 13) in the independent functional area of the housing 1, and connect the power supply and signal lines;
[0033] 2. Next, install the electrolyte receiving shaft 9 on the angle adjustment bracket 6, and ensure that the triangular connecting surface is aligned with the corresponding position of the lead screw 7; keep the angle adjustment bracket 6 in a fixed state to ensure that it does not rotate during the adjustment process, so as to provide stable support for the electrolyte module;
[0034] 3. Then, by rotating the knurled nut 8 on the lead screw 7, the two knurled nuts move linearly along the lead screw, thereby pushing the electrolyte receiving shaft 9 located between the two nuts to produce a small displacement; this small displacement acts on the electrolyte module to achieve angle fine adjustment, so that the electrolyte detection surface is consistent with the direction of gravity or flow; subsequently, the reference angle of the tilt sensing module is set as the current electrolyte module attitude, realizing the coordinate alignment of the two sensing systems and ensuring the consistency and accuracy of the measurement data;
[0035] 4. Finally, the internal lithium battery 13 is powered by the charging port 10 on the same side of the outer casing 1. The glue rod antenna 11 is connected to the external communication module to realize wireless data transmission. After that, in daily use, if it is necessary to make fine adjustments to the tilt angle or electrolyte module, the position of the electrolyte receiving shaft 9 can be adjusted by rotating the knurled nut 8 again. There is no need to disassemble the outer casing or rotate the angle adjustment bracket 6. The gap between the inner groove 32 and the U-shaped shaft 62 can buffer the stress generated by fine adjustment and ensure the long-term stability and durability of the structure.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
