[0030] The embodiments of the present application are described in detail below with reference to the drawings.

Wherein, the preset direction is the length direction of the base 210, and the stator 200 is suitable for linear motor.

[0032] Please see Figure 2 And Figure 3 The utility model embodiment provides a magnetic pole detection module 100 for detecting the magnetic poles of the plurality of permanent magnets 220 of the stator 200, and the magnetic pole detection module 100 includes a mounting piece 110 and a plurality of magnetic pole sensing units 120. The mounting piece 110 is arranged along the extension direction, and the plurality of magnetic pole sensing units 120 are sequentially arranged along the extension direction of the mounting piece 110. Each magnetic pole sensing unit 120 includes a support piece 121, a magnetic pole sensing piece 122 and a prompt piece 123. The support piece 121 is slidably connected with the mounting piece 110 along the extension direction of the mounting piece 110. The magnetic pole sensing piece 122 is arranged on the support piece 121 and is used for sensing the magnetic pole of the permanent magnet 220. The prompt piece 123 is arranged on the support piece 121 and is electrically connected with the magnetic pole sensing piece 122, and is used for sending prompt information based on the magnetic pole sensed by the magnetic pole sensing piece 122. Wherein, the magnetic pole sensing piece 122 can be a hall element.

[0033] Exemplarily, the mounting piece 110 is substantially cuboid, and the number of the magnetic pole sensing units 120 is the same as the number of the permanent magnets 220. It can be understood that in other embodiments, the number of the magnetic pole sensing units 120 is greater than the number of the permanent magnets 220.

[0034] Please see Figure 3 And Figure 4In some embodiments, the support 121 comprises a support plate 1211 and a sliding body 1212. The magnetic pole sensing member 122 and the prompting member 123 are both arranged on the support plate 1211, and the sliding body 1212 is connected to the support plate 1211. The mounting member 110 is provided with a guide body 110a on the side facing the support 121, and the sliding body 1212 and the guide body 110a are slidingly and clampingly fitted along the extension direction of the mounting member 110.

[0035] Therefore, through the above arrangement, the sliding adjustment difficulty of the support 121 and the mounting member 110 can be reduced, and the adjustment efficiency of the position of the support 121 relative to the mounting member 110 can be improved.

[0036] In some embodiments, one of the sliding body 1212 and the guide body 110a is a protrusion, and the other is a groove. Therefore, through the above arrangement, the manufacturing cost of the sliding body 1212 and the guide body 110a can be reduced.

[0037] For example, the sliding body 1212 is a protrusion, and the guide body 110a is a groove, or the sliding body 1212 is a groove, and the guide body 110a is a protrusion.

[0038] Please refer to Figure 4 In another embodiment, the guide body 110a is a groove and is arranged in extension along the extension direction of the mounting member 110, and the sliding body 1212 comprises a sliding part 1212a and a pressing part 1212b. One end of the sliding part 1212a is arranged through the support plate 1211 in the direction of the support plate 1211 facing the mounting member 110 and clamped to the guide body 110a, and the pressing part 1212b is connected to the other end of the sliding part 1212a and located on the side of the support plate 1211 away from the mounting member 110 to press the support plate 1211.

[0039] For example, the sliding body 1212 is a bolt. The sliding part 1212a is the shank of the bolt, and the pressing part 1212b is the head of the bolt.

[0040] Therefore, the above sliding body 1212 can form a pressing force on the support plate 1211 in the direction of the support plate 1211 facing the mounting member 110 on the basis of being clamped to the guide body 110a, and the stability of the position of the support plate 1211 relative to the mounting member 110 is improved.

[0041] In some embodiments, the guide body 110a and the sliding body 1212 are both two, the two guide bodies 110a are arranged in parallel and spaced apart, and the two sliding bodies 1212 correspond to the two guide bodies 110a one by one.

[0042] In this embodiment, the support plate 1211 is substantially a cuboid, the two sliding bodies 1212 are respectively located at the two ends of the support plate 1211 in the length direction, and the magnetic pole sensing member 122 is arranged between the two sliding bodies 1212.

[0043] Therefore, the two sliding bodies 1212 and the two guide bodies 110a cooperate to form two positioning points on the support plate 1211, so as to fix the support plate 1211 to the mounting member 110 at both ends in the length direction of the support plate 1211, and the stability of the position of the support plate 1211 relative to the mounting member 110 can be further improved.

[0044] Referring to Figure 4 In some embodiments, the mounting member 110 is provided with a plurality of identification units 130, the plurality of identification units 130 are sequentially arranged along the extension direction of the mounting member 110 and correspond to the plurality of magnetic pole sensing units 120 one by one, and each identification unit 130 includes a plurality of scale lines 131 sequentially arranged along the extension direction of the mounting member 110, and the plurality of scale lines 131 are used to display the position of the corresponding magnetic pole sensing unit 120 relative to the mounting member 110.

[0045] In this embodiment, the identification unit 130 is arranged on the side of one of the guide bodies 110a away from the other guide body 110a, and is used to display the position of the corresponding support plate 1211 relative to the mounting member 110. It can be understood that in other embodiments, the side of each guide body 110a away from the other guide body 110a is also provided with an identification unit 130.

[0046] Therefore, the interval between any two adjacent support plates 1211 can be determined by the plurality of identification units 130, so as to determine the interval between any two adjacent magnetic pole sensing units 120, and the adjustment efficiency of the distance between the plurality of magnetic pole sensing units 120 is improved.

[0047] Referring to Figure 2 and Figure 3 In some embodiments, the magnetic pole detection module 100 further includes a cover member 140. The cover member 140 is provided with a containing groove 140a and is arranged on the mounting member 110, and the cover member 140 is a light-transmitting structure. The plurality of magnetic pole sensing units 120 are contained in the containing groove 140a.

[0048] Therefore, the containing groove 140a can protect the plurality of magnetic pole sensing units 120 from being collided by external components, so as to improve the service life of the plurality of magnetic pole sensing units 120. In addition, the cover member 140 can also improve the overall aesthetics of the magnetic pole detection module 100.

[0049] In some embodiments, the cover member 140 includes a top plate 141 and a plurality of side plates 142. The plurality of side plates 142 are sequentially connected end to end and are arranged on the mounting member 110, the top plate 141 is detachably connected with the plurality of side plates 142, and the top plate 141 and the plurality of side plates 142 form the containing groove 140a. The top plate 141 and the plurality of side plates 142 are light-transmitting structures.

[0050] Therefore, through the above setting, the cover piece 140 is set in parts, which can reduce the manufacturing cost of the cover piece 140 and facilitate the disassembly of the cover piece 140.

[0051] Please refer to Figure 2 and Figure 3 In some embodiments, the magnetic pole detection module 100 further comprises a plurality of positioning pieces 150. The plurality of positioning pieces 150 are connected to the side of the mounting piece 110 away from the plurality of magnetic pole sensing units 120, for guiding the magnetic pole detection module 100 to the base 210 of the stator 200.

[0052] In this embodiment, the positioning pieces 150 are two, and the two positioning pieces 150 are arranged in the width direction of the mounting piece 110. It can be understood that in other embodiments, the positioning pieces 150 can also be three or more.

[0053] In use, the plurality of positioning pieces 150 can be abutted to the side edges of the base 210, thereby positioning the mounting piece 110, which is beneficial to improve the detection accuracy of the magnetic pole detection module 100.

[0054] In some embodiments, the prompt piece 123 is a display lamp. When the magnetic poles of the plurality of permanent magnets 220 are sequentially and alternately arranged in a predetermined direction, the colors displayed by the corresponding two prompt pieces 123 are the same when the magnetic poles detected by any two adjacent magnetic pole sensing units 122 are opposite. For example, the colors displayed by the prompt pieces 123 can be green and red.

[0055] Therefore, through the above setting, if the magnetic poles of the plurality of permanent magnets 220 are sequentially and alternately arranged, the plurality of prompt pieces 123 display a unified color, for example, green. If the magnetic poles of some of the permanent magnets 220 are assembled incorrectly, the corresponding prompt pieces 123 will display a color different from the colors displayed by the other prompt pieces 123, for example, red, which is beneficial to improve the detection efficiency of the magnetic pole detection module 100.

[0056] In the above magnetic pole detection module 100, by adjusting the position of the support piece 121 relative to the mounting piece 110, the spacing between any two adjacent magnetic pole sensing units 120 can be adjusted to detect a plurality of different stators 200, thereby improving the application range of the magnetic pole detection module 100. In addition, the plurality of magnetic pole sensing units 120 are sequentially arranged in the extension direction of the mounting piece 110. After adjusting the plurality of magnetic pole sensing units 120 based on the mutual spacing of the plurality of permanent magnets 220 in the stator 200, the magnetic pole detection module 100 can complete the detection of the magnetic poles of the plurality of permanent magnets 220 in the stator 200 at a time, thereby improving the detection efficiency.

Consequently, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
