Description

Technical Field

[0001] The invention relates to the technical field of Hall device installation, and in particular to an adjustable fixing bracket for a Hall device. Background Art

[0002] A Hall device is a sensor element that uses the Hall effect to detect magnetic fields. When current passes through a semiconductor wafer perpendicular to the external magnetic field, charge accumulates on one side of the wafer, forming a potential difference, namely the Hall voltage. This voltage is proportional to the product of the magnetic induction intensity and the excitation current, and inversely proportional to the thickness of the wafer. The magnitude of the magnetic induction intensity can be determined by measuring the Hall voltage. During use, the Hall device needs to be fixed with a fixed bracket to ensure the stability of the Hall device itself during the measurement process.

[0003] In actual use, due to the various sizes of Hall devices, when using the same fixing bracket to clamp and fix Hall devices of different sizes, special attention should be paid to adjusting the moving distance of the clamping rod. If the operator is inexperienced and the size of the Hall device changes, if the distance the clamping rod moves toward the Hall device is not adjusted accurately, it is easy to cause the clamping rod to over-clamp the Hall device, which may damage the external structure of the Hall device and affect its normal use. Summary of the invention

[0024] Combine the following Figure 1-Figure 10 The invention describes an adjustable fixing bracket for a Hall device.

[0025] like Figure 1-Figure 6 As shown, in one embodiment, it includes a base 1, a disc 43, a rotating shaft 3, a protrusion 2, a moving groove 102, a positioning component 4 and a buffer component 5.

[0026] The base 1 is provided with a slot 101 and a mounting hole; a disc 43 is movably mounted in the slot 101; a rotating shaft 3, one end of which is fixedly mounted on the bottom of the disc 43 and the other end of which movably passes through the bottom of the base 1; a protrusion 2, which is fixedly mounted on the middle of the top of the base 1 and is used for preliminary positioning of the Hall device; a movable groove 102, a circular array is opened on the surface of the base 1, and the number is set to be multiple; a positioning component 4, which is slidably connected to the movable groove 102 and adapted to the disc 43, and is used for further positioning the Hall device; a buffer component 5, which is arranged in the positioning component 4, is used to prevent the positioning component 4 from excessively squeezing and positioning Hall components of different sizes.

[0027] Specifically, the base 1 is installed on the device by screwing screws through the mounting holes. A notch is provided at the bottom of the Hall device that can be adapted to the protrusion 2, so that the Hall device can be preliminarily positioned on the surface of the base 1. In the present application, the number of movable grooves 102 is designed to be three, and the number of positioning components 4 is also set to three. The Hall device with a circular appearance is limited and fixed, and the rotating shaft 3 is rotated. The rotation of the rotating shaft 3 drives the disk 43 set in the notch 101 to rotate, so that the three groups of positioning components 4 are moved toward the Hall device along the movable groove 102 to position it. The buffer component 5 abuts against the Hall device before the positioning component 4, so as to avoid excessive squeezing and positioning of the positioning component 4 and the edge of the Hall device, thereby causing damage to the Hall device.

[0028] See also Figure 2-Figure 5 As shown, in this embodiment, the positioning assembly 4 includes a movable block 41, which is slidably connected to the movable groove 102, a positioning rod 42 is fixedly arranged at the bottom of the movable block 41, and a plurality of curved grooves 44 are opened in a circular array on the disk 43, and the end of the positioning rod 42 away from the movable block 41 is slidably fitted with the curved groove 44.

[0029] Specifically, the rotating shaft 3 is rotated, and the rotation of the rotating shaft 3 drives the disk 43 to rotate. The rotation of the disk 43 drives the curved groove 44 to rotate, thereby driving the positioning rod 42 to move. The movement of the positioning rod 42 will drive the movable block 41 to move along the movable groove 102 toward the direction close to the Hall device, so that the Hall device can be positioned. The rotation angle of the disk 43 determines the moving distance of the movable block 41. According to the Hall devices of different diameters, the moving distance of the movable block 41 can be controlled by adjusting the rotation angle of the disk 43, so that Hall devices of different sizes can be positioned.

[0030] See also Figure 6-Figure 7 As shown, in this embodiment, the buffer assembly 5 includes a movable plate 51, a transverse groove 52 is opened in the movable block 41, the movable plate 51 is slidably connected to the transverse groove 52, one end of the movable plate 51 away from the transverse groove 52 is movably abutted against the Hall device, and the movable plate 51 is connected to the inner wall of the transverse groove 52 by a positioning spring 53.

[0031] Specifically, when the movable block 41 moves toward the Hall device, it will drive the movable plate 51 to move synchronously. In the initial state, a part of the movable plate 51 will be located outside the transverse groove 52, and the movable plate 51 will abut against the Hall device before the movable block 41. After the movable plate 51 contacts the Hall device, the movable block 41 continues to move. Under the pressure of the Hall device, the movable plate 51 will move toward the inside of the transverse groove 52, thereby compressing the positioning spring 53, which can play a certain buffering role and avoid excessive extrusion.

[0032] See also Figure 8As shown, in this embodiment, a gear 6 is fixedly sleeved on the outer side of the rotating shaft 3 located below the base 1, a rotating disk 7 is movably embedded on the outer side of the rotating shaft 3, a slot 71 is opened on one side of the rotating disk 7, a block 8 is movably arranged in the slot 71, and the other end of the block 8 is movably meshed with the gear 6 for transmission.

[0033] Specifically, when the Hall device needs to be positioned, the rotating disk 7 is rotated. In the initial state, the block 8 is engaged with the slot 71 and meshed with the gear 6. The rotation of the rotating disk 7 will drive the block 8 to rotate, thereby driving the gear 6 to rotate. The rotation of the gear 6 will drive the rotating shaft 3 to rotate, thereby realizing the rotation of the disk 43 and then making the movable block 41 move toward the Hall device for positioning. The movable plate 51 first abuts against the Hall device and then moves toward the inside of the transverse groove 52. When the movable plate 51 is completely moved to the inside of the movable block 41, the movable block 41 just abuts against the Hall device. At this time, the block 8 is moved upward along the slot 71, and the block 8 will be disengaged from the gear 6. At this time, rotating the rotating disk 7 will not drive the gear 6 to rotate, so the rotating shaft 3 will not rotate, and the movable block 41 will not continue to squeeze the Hall device to prevent excessive squeezing and damage to the Hall device.

[0034] See also Figure 3 and Figure 8 As shown, in this embodiment, the rotating shaft 3 is provided with a vertical groove 31 above the gear 6 , a circular ring 9 is movably arranged in the vertical groove 31 , and a connecting rod 10 is fixedly arranged between the bottom of the circular ring 9 and the clamping block 8 .

[0035] Specifically, when positioning the Hall device, the rotation of the rotating disk 7 will drive the block 8, the gear 6, the connecting rod 10, the ring 9 and the rotating shaft 3 to rotate synchronously, and the movable block 41 will move toward the Hall device. When the movable block 41 abuts against the Hall device, the ring 9 moves upward. The upward movement of the ring 9 along the vertical groove 31 will drive the connecting rod 10 and the block 8 to move upward, and the block 8 will no longer engage with the gear 6. At this time, the rotation of the rotating disk 7 will only drive the block 8, the connecting rod 10 and the ring 9 to rotate together, the gear 6 and the rotating shaft 3 will not rotate, and the movable block 41 will no longer continue to move toward the Hall device, thereby avoiding excessive squeezing of the Hall device.

[0036] See also Figure 3 As shown, in this embodiment, a circular groove 91 is opened on the outer side of the circular ring 9, and a movable frame 11 is movably arranged in the circular groove 91. The movable frame 11 movably penetrates the base 1 at one end away from the circular ring 9 and the end is located above the base 1.

[0037] Specifically, during positioning, when the movable block 41 abuts against the Hall device, the movable frame 11 moves upward. The upward movement of the movable frame 11 will drive the ring 9 to move upward through the action of the circular groove 91. The upward movement of the ring 9 will drive the connecting rod 10 and the block 8 to move upward so that the block 8 is no longer engaged with the gear 6. Subsequently, the rotation of the rotating disk 7 will not drive the rotating shaft 3 to rotate.

[0038] See also Figure 6 As shown, in this embodiment, a lifting rod 12 is movably arranged in the transverse groove 52, a return spring 13 is fixedly arranged between the top of the lifting rod 12 and the inner wall of the transverse groove 52, and the end of the lifting rod 12 away from the transverse groove 52 is slidably fitted with the bottom of the movable frame 11.

[0039] Specifically, when positioning the Hall device, the movable block 41 moves laterally along the movable groove 102, and the lifting rod 12 slides along the bottom of the movable frame 11. When the movable block 41 abuts against the Hall device, the lifting rod 12 moves upward. This process will compress the reset spring 13. The upward movement of the lifting rod 12 will drive the movable frame 11 to move upward, thereby disengaging the blocking block 8 from the gear 6. Subsequently, the rotation of the rotating disk 7 will not drive the rotating shaft 3 to rotate synchronously, and the movable block 41 will not excessively squeeze the Hall device.

[0040] See also Figure 5-Figure 6 As shown, in this embodiment, a moving block 14 is fixedly provided on the top of the movable plate 51 , and the moving block 14 has an inclined slot 141 . A limiting rod 15 is fixedly provided on the bottom of the lifting rod 12 , and the limiting rod 15 is movably abutted against the inclined slot 141 .

[0041] Specifically, when positioning the Hall device, the movable plate 51 first contacts the Hall device and then moves toward the inside of the transverse groove 52. The movement of the movable plate 51 will drive the moving block 14 to move. During the movement of the moving block 14, the inclined groove 141 will be driven to move. The limiting rod 15 will move upward along the bottom of the inclined groove 141, and the limiting rod 15 will move upward to drive the lifting rod 12 to move upward, so that the movable frame 11 and the block 8 both move upward. When the limiting rod 15 moves to the highest point of the inclined groove 141, the movable plate 51 just moves to the inside of the transverse groove 52, the movable block 41 abuts against the Hall device, and the block 8 is disengaged from the gear 6. At this time, the rotation of the rotating disk 7 will not drive the rotating shaft 3 to move synchronously, and the movable block 41 will not excessively squeeze the Hall device. When it is necessary to release the positioning of the Hall device, the rotating shaft 3 can be rotated in the opposite direction.

[0042] See also Figure 1-Figure 3 , Figure 5 and Fig. 9As shown, in this embodiment, a fixed plate 16 is fixedly provided on the base 1 at one side of the movable block 41, and a plurality of limiting holes 161 are provided in a transverse linear array on the fixed plate 16. A circular hole 17 is provided on the side of the movable block 41 close to the fixed plate 16, and a limiting ball 18 is provided at one end of the movable plate 51 close to the circular hole 17, and the limiting ball 18 is movably engaged with the circular hole 17 and the limiting hole 161.

[0043] Specifically, the movable block 41 moves toward the Hall device with the movable plate 51. After the movable plate 51 contacts the Hall device, it moves toward the inside of the transverse groove 52. The limiting ball 18 is made of elastic material. Before the limiting ball 18 reaches the circular hole 17, it abuts against the inner wall of the movable block 41 and is in a compressed state. When the limiting ball 18 moves to the position of the circular hole 17, it stretches and engages with one of the limiting holes 161 opened in the circular hole 17 and the fixed plate 16, thereby ensuring that the movable block 41 no longer moves and ensuring the stability of positioning. The design of multiple limiting holes 161 can meet the positioning requirements of Hall devices of different diameters.

[0044] See also Fig.10 As shown, in this embodiment, a positioning ring 19 is fixedly provided in the limiting hole 161, a push rod 20 is movably provided through the center of the positioning ring 19, one end of the push rod 20 is movably abutted against the limiting ball 18, and a connecting spring 21 is fixedly provided between the push rod 20 and the positioning ring 19.

[0045] Specifically, when it is necessary to release the engagement between the limiting ball 18 and the limiting hole 161 and the circular hole 17, the limiting hole 161 moves the push rod 20 inward, and the inward movement of the push rod 20 will push the limiting ball 18 to release the engagement with the limiting hole 161 and the circular hole 17, and the movable plate 51 can move relative to the movable block 41. During this process, the connecting spring 21 will be compressed, and then the force applied to the push rod 20 will be removed. Under the action of the connecting spring 21, the push rod 20 will be driven to move back to the initial position, and the positioning ring 19 provides support for the connecting spring 21.

[0046] During implementation, the base 1 is installed on the device by screwing the screws through the mounting holes. A notch is provided at the bottom of the Hall device to fit with the protrusion 2, so that the Hall device can be initially positioned on the surface of the base 1. When the Hall device needs to be positioned, the rotating disk 7 is rotated. In the initial state, the block 8 is engaged with the slot 71 and meshes with the gear 6. The rotation of the rotating disk 7 drives the block 8 to rotate, thereby driving the gear 6 to rotate. The rotation of the gear 6 drives the rotating shaft 3 to rotate, thereby realizing the rotation of the disc 43. The rotation of the disc 43 drives the curved groove 44 to rotate, thereby driving the positioning rod 42 to move, and the positioning rod 4 2 will drive the movable block 41 to move along the movable groove 102 toward the direction close to the Hall device, so that the Hall device can be positioned. The rotation angle of the disk 43 determines the moving distance of the movable block 41. According to the Hall devices of different diameters, the moving distance of the movable block 41 can be controlled by adjusting the rotation angle of the disk 43, so that the Hall devices of different sizes can be positioned. The movable plate 51 first abuts against the Hall device and then moves toward the inside of the transverse groove 52. When the movable plate 51 is completely moved into the movable block 41, the movable block 41 just abuts against the Hall device. The movement of the movable plate 51 will drive the movable block 41 to move along the movable groove 102 toward the direction close to the Hall device, so that the Hall device can be positioned. The movable block 14 moves, and the movement of the movable block 14 will drive the inclined slot 141 to move. The limiting rod 15 will move upward along the bottom of the inclined slot 141, and the limiting rod 15 will move upward to drive the lifting rod 12 to move upward, so that the movable frame 11 and the block 8 move upward. When the limiting rod 15 moves to the highest point of the inclined slot 141, the movable plate 51 just moves to the inside of the transverse slot 52, the movable block 41 abuts against the Hall device, and the block 8 is disengaged from the gear 6. At this time, the rotation of the rotating disk 7 will not drive the rotating shaft 3 to move synchronously, and the movable block 41 will not excessively squeeze the Hall device. The movable block 41 moves toward the Hall device together with the movable plate 51. After the movable plate 51 contacts the Hall device, it moves toward the inside of the transverse groove 52. The limiting ball 18 is made of elastic material. Before the limiting ball 18 reaches the circular hole 17, it abuts against the inner wall of the movable block 41 and is in a compressed state. When the limiting ball 18 moves to the position of the circular hole 17, it stretches and engages with one of the limiting holes 161 opened in the circular hole 17 and the fixed plate 16, ensuring that the movable block 41 no longer moves and ensuring the stability of positioning. The design of multiple limiting holes 161 can meet the positioning requirements of Hall devices with different diameters.
