Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an auxiliary transmission structure of an angle sensor. Background Art

[0002] Angle sensors are widely used in the fields of automobiles, machinery, aviation, aerospace, navigation, industrial automation, etc. It is mainly divided into contact and non-contact types. As the contact angle sensor grows in use, it will have disadvantages such as mechanical wear, reduced accuracy, frequent maintenance and even replacement of new equipment. This not only increases the production cost but also makes it easy for the quality of the measured equipment to be unguaranteed. The non-contact angle sensor overcomes these shortcomings. Commonly used non-contact angle sensors are photoelectric and magnetoelectric. Although the photoelectric type has higher accuracy than the magnetoelectric type, it has harsh environmental requirements and poor seismic resistance, so it is not suitable for industrial sites with more complex environments. It is precisely based on these problems that magnetic angle sensors are widely used in various occasions.

[0003] As described in the published patent CN219122385U, the magnetic field sensor is also called a magnetic angle sensor. The magnet used to generate the magnetic field is installed on a rotating shaft, which is connected to the shaft of the object to be detected for rotation angle. After the rotating shaft is driven to rotate by the object to be detected for rotation angle, the magnetic field direction of the magnet changes accordingly. The magnetic resistance sensing element on the PCBA can sense the change in the angle of rotation of the magnet and obtain the rotation angle of the shaft after conversion by the PCBA control board. Magnetic field sensors include Hall effect type, AMR anisotropic magnetoresistance type, GMR giant magnetoresistance type and TMR tunneling magnetoresistance type.

[0004] The above-mentioned magnetic angle sensor drives the magnet to rotate through the rotating shaft, thereby providing better sensing support for the accurate determination of the angular position of the detected object. However, in actual application, due to the limitations of the installation environment, the rotating shaft of the magnetic angle sensor cannot be directly fixedly connected to the object to be detected. Therefore, it is necessary to use a conversion structure to enable the object to be detected and the above-mentioned angle sensor to achieve mutual transmission connection. This application aims to design an auxiliary transmission structure to solve the problem of inconvenient transmission connection between the angle sensor and the object to be detected due to the limitations of the installation environment.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-7 , an auxiliary transmission structure of an angle sensor, comprising a first mounting column 100 and a first transmission rod 200, wherein the first mounting column 100 is fixedly mounted on a housing of the angle sensor 001, one end of the first transmission rod 200 is fixedly connected to a rotating shaft of the angle sensor, the other end of the first transmission rod 200 is connected to a cable member 300, a second mounting column 210 is fixedly mounted on the first transmission rod 200, and an elastic connecting member 400 is installed between the first mounting column 100 and the second mounting column 210;

[0030] As described in the patent of a magnetic angle sensor previously disclosed by the applicant (publication number CN219122385U), the magnetoresistive sensor is a tunnel magnetoresistive sensor (TMR). When the shaft drives the magnet to rotate, it uses the tunnel magnetoresistive effect of the magnetic multilayer film material to sense the magnetic field. It has a larger resistance change rate than anisotropic magnetoresistive (AMR) and giant magnetoresistive (GMR) sensing elements, providing better sensing support for the accurate determination of the angular position of the detected object.

[0031] In summary, in the prior art, the working principle of the magnetic angle sensor 001 is mainly to calculate the angle by driving the magnet to rotate through the rotating shaft. In general, during use, the detected object needs to be directly fixedly connected to the rotating shaft. During the rotation of the detected object, the rotating shaft is directly driven to rotate, so that the angle of the detected object can be quickly calculated. However, in actual use, due to the actual installation environment, the rotating shaft cannot be directly connected to the detected object. Therefore, in this case, it is necessary to use an auxiliary transmission structure to connect the magnetic angle sensor 001 and the detected object.

[0032] like Figure 3As shown, in the actual use of the present invention, one end of the first transmission rod 200 is fixedly connected to the rotating shaft of the magnetic angle sensor, and the other end of the first transmission rod 200 is connected to a cable member 300, wherein one end of the cable member 300 is connected to the first transmission rod 200, and the other end of the cable member 300 is fixed on the detected object. When the detected object rotates, the cable member 300 is pulled to make the first transmission rod 200 swing. During the swinging of the first transmission rod 200, the rotating shaft of the magnetic angle sensor is driven to rotate, so that the rotation of the detected object and the rotation of the rotating shaft of the magnetic angle sensor are fed back in real time. The connection between the cable member 300 and the detected object is simple and fast, making the installation and connection of the magnetic angle sensor 001 more convenient, and the length of the cable member 300 can be increased / decreased according to actual needs. The connection between the magnetic angle sensor 001 and the detected object is more flexible and changeable, and can adapt to the installation and use in a variety of complex environments, and has a wider range of applications. By installing an elastic connector 400 between the first mounting column 100 and the second mounting column 210, when the detected object is reset and rotated, under the action of the elastic connector 400, the first transmission rod 200 will also be reset and rotated, so that the reset rotation angle can be measured, and the measurement and use range is wider. By changing the fixed position of the cable member 300 on the first transmission rod 200, the force application position of the cable member 300 on the first transmission rod 200 can be changed, and the starting torque of the cable member 300 on the magnetic angle sensor 001 can be changed, so that the utility model can be adjusted in real time according to actual use requirements, and is more in line with the needs of the actual working environment;

[0033] During use of the utility model, the first transmission rod 200 is driven to swing by the cable member 300, so that the angle change of the detected object can be quickly transmitted to the magnetic angle sensor 001, and the first transmission rod 200 adopts a swinging working mode, so the connection angle between the cable member 300 and the first transmission rod 200 can be wider. Within a larger angle range, the cable member 300 can drive the first transmission rod 200 to swing. The transmission structure of the utility model has the advantages of simple structure, easy operation and high measurement accuracy, which effectively solves the difficulties when the installation space is limited or the installation angle needs to be accurately set. It has the advantages of being able to arbitrarily design the required control length, arbitrarily design the effective angle and starting torque according to the needs, and having a simple design and convenient installation. The transmission is very stable, and the structure is simple and the operation is reliable.

[0034] In the embodiment of the utility model, it also includes a mounting base plate 500 fixedly mounted on the housing of the angle sensor 001, a first positioning block 510 is mounted on the mounting base plate 500, a first mounting column 100 is fixedly mounted on the first positioning block 510, a plurality of positioning block mounting holes 520 are opened on the mounting base plate 500 at equal intervals, the first positioning block 510 is fixedly mounted on the positioning block mounting holes 520, the direction in which the plurality of positioning block mounting holes 520 are arranged is set as a first reference line 003, and in a non-working state, the first transmission rod 200 is close to the first reference line 003 and the elastic connecting member (400) is in a natural length state;

[0035] like Figure 3 As shown, in the non-working state, the first transmission rod 200 is close to the first reference line 003 and the elastic connector 400 is not subjected to force, and the cable member 300 drives the rotating shaft on the magnetic angle sensor 001 to rotate by pulling the first transmission rod 200 to one side, thereby realizing the transmission between the detected object and the magnetic angle sensor 001. In the process of the cable member 300 pulling the first transmission rod, when the cable member 300 pulls the first transmission rod 200 from different angles, in order to cooperate with the force direction of the cable member 300, the force direction of the elastic connector 400 needs to be adjusted so that the elastic connector 400 can be better subjected to force and elastically deformed. Therefore, a plurality of equally spaced positioning block mounting holes 520 are provided on the mounting base plate 500, the first positioning block 510 is fixedly mounted on the positioning block mounting hole 520, and the first mounting column 100 is fixedly mounted on the first positioning block 510. By adjusting the installation of the first positioning block 510 on different positioning block mounting holes 520, the relative position of the first mounting column 100 and the second mounting column 210 can be adjusted, so that the mounting angle of the elastic connecting member 400 can be conveniently adjusted, and the force direction of the elastic connecting member 400 can be adjusted according to the different force directions of the cable member 300, so that the utility model is more in line with actual work needs and has a wider range of applications.

[0036] In the embodiment of the utility model, an extension rod 220 is installed at the front end of the first transmission rod 200, and a plurality of cable installation holes 221 arranged at equal distances are opened on the extension rod 220 along the length direction;

[0037] By installing the cable member 300 on different cable mounting holes 221, the fixed position of the cable member 300 on the first transmission rod 200 can be changed, the force application position of the cable member 300 on the first transmission rod 200 can be changed, and the starting torque of the cable member 300 on the magnetic angle sensor 001 can be changed, so that the utility model can be adjusted in real time according to actual use requirements and better meet the needs of the actual working environment.

[0038] In the embodiment of the utility model, the two ends of the elastic connecting member 400 are respectively provided with a first fixing ring 410 and a second fixing ring 420, and the first fixing ring 410 and the second fixing ring 420 are respectively sleeved on the first mounting column 100 and the second mounting column 210;

[0039] like Figure 3 As shown, during the swinging process of the first transmission rod 200, the angle of the elastic connecting member 400 is constantly changing. In order to adapt to the angle change of the elastic connecting member 400, the first fixing ring 410 and the second fixing ring 420 are respectively mounted on the first mounting column 100 and the second mounting column 210. During the swinging process of the first transmission rod 200, the first fixing ring 410 and the second fixing ring 420 can be rotated and matched on the first mounting column 100 and the second mounting column 210 respectively to adapt to the swing adjustment of the first transmission rod 200.

[0040] In the embodiment of the utility model, a limiting column 530 is fixedly disposed on the mounting base plate 500, and the limiting column 530 is fixedly disposed on the swing path of the first transmission rod 200;

[0041] like Figure 3 As shown, by setting a limiting column 530 on the swing path of the first transmission rod 200, the swing angle of the first transmission rod 200 can be limited to prevent the first transmission rod 200 from swinging too much, causing the elastic connector 400 to deform too much and lose its elasticity.

[0042] In the embodiment of the utility model, the rear end of the first transmission rod 200 is provided with a first fixing hole 230 and a second fixing hole 240 arranged in parallel, and the first transmission rod 200 is fixed on the rotating shaft of the angle sensor through the first fixing hole 230 and the second fixing hole 240;

[0043] like Figure 3 As shown, the first transmission rod 200 is fixed on the rotating shaft of the magnetic angle sensor through the first fixing hole 230 and the second fixing hole 240. The mounting structure is stable, so that the first transmission rod 200 can better drive the rotating shaft of the magnetic angle sensor to swing.

[0044] In the embodiment of the utility model, a mounting through hole 550 is provided on the mounting base plate 500, and the rotating shaft of the angle sensor extends out from the mounting through hole 550;

[0045] The connection between the rotating shaft of the magnetic angle sensor and the first transmission rod 200 is more convenient, the structure is simpler, and the production cost is saved.

[0046] In the embodiment of the utility model, a protective housing 560 is fixedly disposed on the mounting base plate 500, and the first transmission rod 200, the first mounting column 100 and the elastic connecting member 400 are covered in the protective housing 560;

[0047] It plays the role of shielding foreign matter, dust and rainwater, and prolongs the reliability and service life of the utility model.

[0048] In the embodiment of the utility model, an operation window 561 is opened on the side of the protective shell 560, and the line connecting the side wall of the operation window 561 close to the limit column 530 and the limit column 530 passes through the rotation axis of the angle sensor;

[0049] During the swinging process of the first transmission rod 200, it always swings in an arc shape with the rotating shaft of the magnetic angle sensor as the center. When the first transmission rod 200 swings to the position of the limit column 530, the side wall of the operating window 561 close to the limit column 530 and the line connecting the limit column 530 pass through the rotating shaft of the angle sensor, ensuring that the first transmission rod 200 will abut against the side wall of the operating window 561 when abutting against the limit column 530, further ensuring the stability of the limiting effect, and at the same time increasing the force points of the first transmission rod 200 when limiting, reducing the deformation problem of the first transmission rod 200, and extending the service life of the utility model.

[0050] In the embodiment of the utility model, Figure 7 As shown, one end of the cable member 300 is fixedly connected to the first transmission rod 200, and the other end of the cable member 300 is fixedly connected to a strong magnet member 800. During installation, the strong magnet member 800 is adsorbed on the installation position (for example, on the rotating body of the knife switch porcelain bottle). In this way, the strong magnet can be sent up with an insulating rod and adsorbed on the knife switch porcelain bottle 900. The installation is convenient and can be installed without power outage, and no additional locking tools are required.

[0051] In one embodiment of the present invention, semi-fluid 3M glue is applied on the strong magnet and the part to be installed as a method of strengthening and stabilizing the magnet.

[0052] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
