Description

Technical Field

[0001] The utility model relates to the technical field of Hall sensors, in particular to a Hall angular velocity sensor with multiple installation modes. Background Art

[0002] Hall effect-based magnetoelectric sensors feature high sensitivity to magnetic fields, stable output signals, high frequency response, strong immunity to electromagnetic interference, simple structure, and ease of use. They are currently widely used in traction and braking systems for high-speed rail locomotives, urban rail vehicles, electric vehicles, and new energy vehicles. Hall effect speed sensors are also commonly used as encoders for low-voltage AC motors.

[0003] For example, the authorization announcement number "CN205562583U" is called a Hall speed sensor. Although the positioning sleeve does not require perforations for the leads of the Hall IC, its structure is simpler and it is more convenient to assemble the Hall IC. It has the characteristics of better performance, more convenient assembly and lower cost. However, the existing Hall speed sensor still exists. Since the Hall sensor needs to be installed and fixed at the specified position where it needs to be used to work, the Hall sensor requires different fixing methods when facing different detection sources. Therefore, when bolts are conventionally used to directly fix the Hall sensor on the object to be detected, the end of the bolt needs to pass through the surface of the fixed object, which leaves holes for the mounting bolts on the installation point, causing excessive damage, thereby affecting the high installation cost of the Hall speed sensor.

[0004] At the same time, in order to adapt to more usage environments and installation locations, the existing Hall speed sensor has a single installation and fixing method, which makes the installation of the Hall speed sensor more troublesome. For example, the installation space is relatively small and it is not suitable for the operator to fix it with both hands, which will affect the installation efficiency. Similarly, when there is only one crossbar at the location to be fixed, it is difficult to fix the Hall sensor by bolt connection. Therefore, the single installation method will make the application range of the Hall speed sensor relatively narrow. Utility Model Content

[0005] The purpose of the utility model is to solve the problems of high installation cost and small application range of Hall velocity sensors, and to propose a Hall angular velocity sensor with multiple installation methods.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a Hall angular velocity sensor with multiple installation methods, comprising an upper shell, a lower shell and a mounting plate, the inner side of the upper shell being movably connected to the lower shell, and a clamping and mounting fixing structure is provided inside both sides of the upper shell and the lower shell, the clamping and mounting fixing structure comprises a support block, an extension plate and a cushion layer, the two support blocks are respectively fixedly connected to the inner ends of the upper shell and the lower shell, the two extension plates are fixedly installed on the outer sides of the support blocks, the internal threads of the two extension plates are connected to threaded rods, the two ends of the threaded rods are threadedly connected to nuts, the inner sides of the two nuts are movably connected to the extension plates, and the two cushion layers are respectively fixedly connected to the inner walls of the upper shell and the lower shell.

[0007] Preferably, the mounting plate is movably connected to the inner sides of the upper shell and the lower shell, and the outer wall of the mounting plate is movably connected to the inner side of the cushion layer.

[0008] Preferably, a threaded connection fixing structure is provided at the lower end of the lower shell;

[0009] The threaded connection fixing structure includes a movable groove, a threaded tube and a positioning groove;

[0010] The movable groove is fixedly opened at the bottom end of the lower shell, and the interior of the movable groove is slidably connected to a support plate, and two sliders are fixedly connected at both ends of the support plate. Two positioning grooves are opened on both sides of the movable groove, and the interiors of the two sliders are slidably connected to the positioning grooves. The inner sides of the two sliders are movably connected to the movable groove through an insertion rod, and a threaded tube is fixedly installed at the lower end of the support plate, and a threaded hole is fixedly opened on the inner wall of the threaded tube.

[0011] Preferably, a single-rod clamping and lifting structure is provided at the top of the upper shell;

[0012] The single-rod clamping and lifting structure includes an electric push rod, a transverse plate and an arc block;

[0013] The two electric push rods are fixedly installed on both sides of the top of the upper shell, and two transverse plates are fixedly installed on the front ends of the two electric push rods. Arc blocks are fixedly installed on the tops of the two transverse plates. The inner sides of the two arc blocks are relatively movable, and the bottom ends of the two transverse plates are slidably connected to the top of the upper shell.

[0014] Preferably, multiple fixing seats are fixedly connected to both sides of the upper shell and the lower shell, multiple bolts are threadedly connected to the inner sides of the multiple fixing seats, the ends of the multiple bolts are tightly pressed against both sides of the mounting plate, and the multiple fixing seats are arranged parallel to each other.

[0015] Preferably, both sides of the bottom end of the lower shell are fixedly connected with external leads, and two control terminals are fixedly installed on the front ends of the outer walls of the lower shell and the upper shell.

[0016] The present invention proposes a Hall angular velocity sensor with multiple installation methods, which has the beneficial effect of: by respectively placing the inner sides of the upper shell and the lower shell on both sides of the mounting plate to be fixed, the operator then passes the threaded rod through the inside of the two fitted extension plates and tightens it using the nuts at both ends, without the need for bolt holes to achieve installation and fixation, and the installation position can also be protected by the cushion layer, thereby reducing the installation and fixation costs of the Hall angular velocity sensor with multiple installation methods.

[0017] When the installation position is narrow, the slider will drive the support plate to move downward until the support plate drives the lower end threaded tube to protrude a certain distance. In this way, one only needs to align the inner threaded hole of the threaded tube protruding from the bottom end of the lower shell with the threaded head part of the installation position to achieve one-handed installation. When there is only one cross bar at the installation position, the electric push rods on both sides will push the transverse plate to squeeze and translate inward. By utilizing the one-handed installation structure in a narrow space and the lifting structure with only a cross bar at the installation position, the installation and fixation adaptability of the Hall angular velocity sensor with multiple installation methods is expanded.

The clamping and mounting fixing structure 5 includes a support block 51, an extension plate 52 and a cushion layer 55. The two support blocks 51 are respectively fixedly connected to the inner ends of the upper shell 1 and the lower shell 2, and the two extension plates 52 are fixedly installed on the outer side of the support block 51. The inner threads of the two extension plates 52 are connected to threaded rods 53, and the two ends of the threaded rods 53 are threadedly connected to nuts 54. The inner sides of the two nuts 54 It is movably connected to the extension plate 52, and the two pads 55 are respectively fixedly connected to the inner walls of the upper shell 1 and the lower shell 2. The pads 55 are made of a relatively soft silicone material with good protective effect. When fixing the Hall sensor, the inner sides of the upper shell 1 and the lower shell 2 are respectively put on both sides of the mounting plate 3 to be fixed. The support block 51 will drive the extension plates 52 on both sides to close together. At this time, the operator passes the threaded rod 53 through the inside of the two fitted extension plates 52 and tightens it with the nuts 54 at both ends. In this way, the nuts 54 will squeeze and fix the extension plates 52. The silicone pads 55 on the inner sides of the upper shell 1 and the lower shell 2 will protect the outer wall of the mounting plate 3 from being squeezed and damaged. The mounting plate 3 is movably connected to the inner sides of the upper shell 1 and the lower shell 2, and the outer wall of the mounting plate 3 is movably connected to the inner side of the pad 55.

[0027] The two pads 55 are fixedly connected to the inner walls of the upper shell 1 and the lower shell 2 respectively. The pads 55 are made of a relatively soft silicone material with good protective effect. When fixing the Hall sensor, the inner sides of the upper shell 1 and the lower shell 2 are respectively put on both sides of the mounting plate 3 to be fixed. The support block 51 will drive the extension plates 52 on both sides to close together. At this time, the operator passes the threaded rod 53 through the inside of the two fitted extension plates 52 and tightens it with the nuts 54 at both ends. In this way, the nuts 54 will squeeze and fix the extension plates 52. The silicone pads 55 on the inner sides of the upper shell 1 and the lower shell 2 will protect the outer wall of the mounting plate 3 from being squeezed and damaged. The method of squeezing and fixing with the outer nuts not only does not require bolt holes to achieve installation and fixation, but also can protect the installation position through the pads, reducing the installation and fixation costs of the Hall angular velocity sensor with multiple installation methods.

[0028] See also Figure 1-6The lower end of the lower shell 2 is provided with a threaded connection fixing structure 6, which includes a movable groove 61, a threaded tube 63 and a positioning groove 65. The movable groove 61 is fixedly opened at the bottom end of the lower shell 2, and the interior of the movable groove 61 is slidably connected to a support plate 62. Two sliders 66 are fixedly connected at both ends of the support plate 62. The two positioning grooves 65 are opened on both sides of the movable groove 61, and the interior of the two sliders 66 is slidably connected to the positioning groove 65. The inner sides of the two sliders 66 are movably connected to the movable groove 61 through an insertion rod. The lower end of the support plate 62 is fixedly installed with a threaded tube 63. When the installation position is narrow, the insertion rod is pulled out from the positioning groove 65, and then the slider 66 can slide up and down along the inside of the positioning groove 65, and then the slider 66 will drive the support plate 62 to move downward until the support plate 62 drives the lower end threaded tube 63 to explore a certain distance, and then the insertion rod is inserted back into the original position to fix the support plate 62. In this way, you only need to move the bottom end of the lower shell 2 The top of the two transverse plates 72 is fixedly installed with arc blocks 73, and the inner sides of the two arc blocks 73 are relatively movable, and the bottom ends of the two transverse plates 72 are slidably connected to the top of the upper shell 1;

[0029] When the mounting position is narrow, the rod is pulled out of the positioning groove 65, and then the slider 66 can slide up and down along the inside of the positioning groove 65, and then the slider 66 will drive the support plate 62 to move downward until the support plate 62 drives the lower end threaded tube 63 to protrude a certain distance, and the rod is inserted back into the original position to fix the support plate 62. In this way, it is only necessary to align the inner threaded hole 64 of the threaded tube 63 protruding from the bottom end of the lower shell 2 with the threaded head part of the required mounting position and twist it to achieve one-handed installation. When there is only one cross bar at the mounting position, the power can be connected to start the electric push rods 71 ​​on both sides. The electric push rods 71 ​​on both sides will push the transverse plate 72 to squeeze and translate inward. At this time, the transverse plate 72 will push the arc groove inside the end arc block 73 to clamp the mounting position cross bar to complete the lifting and fixing. The one-handed installation structure in a narrow space and the lifting structure with only a cross bar at the mounting position make the installation and fixing adaptability of the Hall angular velocity sensor with multiple mounting methods wider.

[0030] See also Figure 1-6, multiple fixing seats 81 are fixedly connected to both sides of the upper shell 1 and the lower shell 2, and multiple bolts 82 are threadedly connected to the inner sides of the multiple fixing seats 81, and the ends of the multiple bolts 82 are tightly pressed against both sides of the mounting plate 3. The fixing seats 81 on both sides of the upper shell 1 and the lower shell 2 can be screwed into the bolts 82, and the ends of the bolts 82 are tightly pressed against both sides of the mounting plate 3 to reinforce and limit the installation position to prevent the upper shell 1 and the lower shell 2 from sliding after being fixed. The multiple fixing seats 81 are arranged parallel to each other, and external leads 9 are fixedly connected to both sides of the bottom end of the lower shell 2. The external leads 9 are used to connect the Hall sensor inside the shell to the outer wall of the instrument and equipment that needs to detect angular velocity, etc. Two control terminals 4 are fixedly installed on the front end of the outer wall of the lower shell 2 and the upper shell 1.

[0031] Working principle:

[0032] First, the two pads 55 are fixedly connected to the inner walls of the upper shell 1 and the lower shell 2 respectively. The pads 55 are made of a relatively soft silicone material with good protective effect. When fixing the Hall sensor, the inner sides of the upper shell 1 and the lower shell 2 are respectively put on the two sides of the mounting plate 3 to be fixed. The support block 51 will drive the extension plates 52 on both sides to close together. At this time, the operator passes the threaded rod 53 through the inside of the two fitting extension plates 52 and tightens them with the nuts 54 at both ends. In this way, the nuts 54 will squeeze and fix the extension plates 52. The silicone pads 55 on the inner sides of the upper shell 1 and the lower shell 2 will protect the outer walls of the mounting plate 3 from being squeezed and damaged. The method of squeezing and fixing with the outer nuts not only does not require bolt holes to achieve installation and fixation, but also can protect the installation position through the pads.

[0033] Then, when the installation position is narrow, the rod is pulled out of the positioning groove 65, and then the slider 66 can slide up and down along the inside of the positioning groove 65, and then the slider 66 will drive the support plate 62 to move downward until the support plate 62 drives the lower end threaded tube 63 to protrude a certain distance, and then the rod is inserted back into the original position to fix the support plate 62. In this way, it is only necessary to align the inner threaded hole 64 of the threaded tube 63 protruding from the bottom end of the lower shell 2 with the threaded head part of the required installation position and twist it to achieve one-handed installation. When there is only one cross bar at the installation position, the power can be connected to start the electric push rods 71 ​​on both sides. The electric push rods 71 ​​on both sides will push the transverse plate 72 to squeeze and translate inward. At this time, the transverse plate 72 will push the arc groove inside the end arc block 73 to clamp the installation position cross bar to complete the lifting and fixing;

[0034] Finally, the bolts 82 can be screwed into the fixing seats 81 on both sides of the upper shell 1 and the lower shell 2, and the ends of the bolts 82 are pressed against both sides of the mounting plate 3 to reinforce and limit the installation position to prevent the upper shell 1 and the lower shell 2 from sliding after being fixed. The external lead 9 is used to connect the Hall sensor inside the shell to the outer wall of the instrument and equipment that needs to detect angular velocity.
