Description

Technical Field

[0001] This utility model belongs to the field of position sensor technology, and specifically relates to a magnet assembly for a position sensor. Background Technology

[0002] A position sensor is a sensor that detects the position of a measured object and converts it into a usable output signal. Unlike displacement sensors, position sensors come in two types: contact and proximity.

[0003] In existing technologies, position sensors are widely used in industrial automation, automotive, and consumer electronics. These sensors typically rely on magnetic components to provide a stable magnetic field or alter the characteristics of the magnetic field to detect the position of an object.

[0004] In most existing magnet assemblies, the magnets are installed inside the position sensor through a package. After a long period of time, the magnets inside the assembly need to be replaced or inspected. Since most existing magnet packages are fixed with bolts, the cover is not easy to remove quickly, making the removal of the package time-consuming and laborious. Utility Model Content

[0005] The purpose of this invention is to provide a magnet assembly for a position sensor, which, through the design of a top cover, facilitates the quick and easy disassembly of the encapsulation box, thereby improving the convenience of subsequent maintenance and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a magnet assembly for a position sensor, comprising a base, a top cover sealed on the base, an installation groove on the base, and an adjustment assembly and a permanent magnet installed in the installation groove;

[0007] A sealing plate is installed at the bottom of the top cover. Slots are provided on both sides of the top cover. Adjustment grooves are provided in both sets of slots. A first spring is installed on the inner wall of both sets of adjustment grooves. A movable plate is installed at one end of each set of first springs. The two sets of movable plates are slidably connected in the two sets of adjustment grooves. A positioning block is installed on the side of each set of movable plates away from the first spring. The bottom of each set of positioning blocks is set as an inclined surface.

[0008] Furthermore, a sealing groove is provided on the mounting groove, the sealing groove is engaged with the sealing plate, and a sealing gasket is provided inside the sealing groove.

[0009] Furthermore, both ends of the top of the base are equipped with locking blocks, and the two sets of locking blocks are respectively engaged in two sets of locking slots.

[0010] Furthermore, both sets of the card blocks are provided with positioning holes, which are used in conjunction with the two sets of positioning blocks respectively.

[0011] Furthermore, mounting plates are installed on both outer walls of the base, and mounting holes are provided on the mounting plates. At least two sets of mounting plates are provided on one side of the base.

[0012] Furthermore, the adjustment assembly includes two sets of second springs, which are respectively installed on the inner walls at both ends of the mounting groove.

[0013] Furthermore, the adjustment assembly also includes two sets of clamping plates, which are respectively installed at opposite ends of the two sets of second springs, and both sets of clamping plates are slidably connected in the mounting groove.

[0014] The beneficial effects of this utility model are:

[0015] This utility model, through the setting of a locking block and a locking slot, allows for the replacement or testing of permanent magnets by pressing the positioning block. This causes the positioning block to compress the first spring via a moving plate, which in turn moves the moving plate within the adjustment slot, separating the positioning block from the positioning hole. This releases the limiting effect on the locking block, allowing the top cover to be disassembled quickly. This makes the disassembly of the packaging box convenient and fast, improving the ease of subsequent maintenance.

[0016] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a magnet assembly for a position sensor. It includes a base 110, a top cover 120 sealed and mounted on the base 110, and a mounting groove 111 formed on the base 110. An adjustment assembly and a permanent magnet 210 are installed in the mounting groove 111.

[0025] A sealing plate 121 is installed at the bottom of the top cover 120. Slots 122 are provided on both side walls of the top cover 120. Adjustment slots 123 are provided in both sets of slots 122. A first spring 124 is installed on the inner wall of both sets of adjustment slots 123. A movable plate 125 is installed at one end of each set of first springs 124. The two sets of movable plates 125 are slidably connected in the two sets of adjustment slots 123. A positioning block 126 is installed on the side of each set of movable plates 125 away from the first spring 124. The bottom of each set of positioning blocks 126 is set as an inclined surface.

[0026] When the permanent magnet 210 needs to be replaced or inspected, the positioning block 126 is pressed, causing the positioning block 126 to squeeze the first spring 124 through the moving plate 125. This causes the moving plate 125 to move within the adjusting groove 123, separating the positioning block 126 from the positioning hole 131. This releases the restriction on the locking block 130, allowing the top cover 120 to be disassembled quickly. This makes the disassembly of the packaging box convenient and quick, improving the ease of later maintenance.

[0027] A sealing groove 112 is provided on the mounting groove 111. The sealing groove 112 is engaged with the sealing plate 121. A sealing gasket is provided inside the sealing groove 112.

[0028] By setting the sealing groove 112 and the sealing gasket, external dust and moisture are prevented from entering the mounting groove 111, thus preventing the permanent magnet 210 from degrading in performance or being damaged due to moisture. At the same time, it prevents impurities such as dust and iron powder from entering the magnet assembly, thus avoiding affecting the uniformity of the magnetic field of the permanent magnet 210 and ensuring the accuracy and reliability of the sensor.

[0029] Both ends of the top of the base 110 are equipped with locking blocks 130, and the two sets of locking blocks 130 are respectively locked into the two sets of locking slots 122.

[0030] A slot 122 is provided for mounting the top cover 120 onto the base 110, thereby sealing the base 110 and mounting the permanent magnet 210.

[0031] Both sets of the card blocks 130 are provided with positioning holes 131, and the two sets of positioning holes 131 are used in conjunction with the two sets of positioning blocks 126 respectively.

[0032] The positioning block 126 and positioning hole 131 are provided to limit the position of the locking block 130, so that the top cover 120 and the base 110 are not easy to fall off when the magnet assembly is in use, thus improving the stability of the permanent magnet 210 during use.

[0033] Mounting plates 140 are installed on both outer walls of the base 110. Mounting plates 140 have mounting holes 141, and at least two sets of mounting plates 140 are provided on one side of the base 110.

[0034] The mounting plate 140 and mounting holes 141 are provided to facilitate the installation of the magnet assembly inside the position sensor, thereby making it easy to install and fix the magnet assembly to ensure proper fit and stable operation of the magnet assembly and the position sensor.

[0035] The adjustment assembly includes two sets of second springs 310 and clamping plates 320. The two sets of second springs 310 are respectively installed on the inner walls of both ends of the mounting groove 111, and the two sets of clamping plates 320 are respectively installed on the opposite ends of the two sets of second springs 310, and both sets of clamping plates 320 are slidably connected in the mounting groove 111.

[0036] The second spring 310 and the clamping plate 320 are provided so that the mounting groove 111 can fix permanent magnets 210 of different sizes, thereby improving the application range of permanent magnets 210.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
